Precautions for riding escalators

Pay special attention to the most vulnerable parts of the escalator:

1. The gap between the steps and the apron board

According to relevant regulations, the horizontal gap between the apron board and the steps and pedals should not be greater than 4mm, and the child’s fingers are 7~8mm thick, and the arms are thicker. The apron board is still in the gap and the steps are moving. It will generate momentum to bring the child's fingers or even arms into the gap. In addition, some children like to lean their feet on the apron board when riding the escalator, and if they accidentally roll the toe of their shoes, laces or trousers into the gap, they will also bring their feet in.

2. The gap between the pedal and the end comb plate

Children have small fingers and poor balance. Once they fall on the escalator, they can easily cause injuries.

3. The handrail groove under the escalator

More than a dozen black rubber bands are wrapped around the entrance of the handrail groove, and they are connected to the button under the escalator. When the child's hand reaches into the rubber band, the connected button is touched, so the escalator will stop immediately. The escalator has an automatic protection function, and it will automatically stop when it encounters an obstruction. However, there is a value for the resistance when encountering obstacles, and the protection function will only respond when this value is reached.

4. The angle between the handrail and the structure

The child is curious and can't predict the immediate danger. When he lifts his head out of the escalator to look down, accidents are likely to occur.

Conditions and technical requirements of observation elevators

Observation elevators can be installed inside or outside of new buildings, and can also be implemented as projects for renovation of existing buildings. It is worth noting that the observation elevators installed outside the building must meet special conditions to resist the adverse effects of the meteorological conditions at the installation site on the elevator equipment.

Ice and frost pose a great threat to the operation of general-purpose load outdoor sightseeing elevators. Industry insiders suggest that it is not suitable to install outdoor observation elevators in places where icing and frost occur frequently. In places where icing and frost do not occur frequently, once icing and frost occur, outdoor sightseeing elevators should be stopped. Windy weather may be the second reason why people have to reduce the speed of outdoor sightseeing elevators or stop elevators. Places with frequent strong winds are not suitable for installation of outdoor sightseeing elevators, unless the elevator shaft is located in a location that is completely sheltered from the outside of the building. Therefore, in this case, it is very important that an indoor elevator must be installed in the building, so that when the weather conditions are not conducive to the operation of the outdoor elevator, the indoor elevator can still ensure uninterrupted vertical transportation.

Moderate rainfall and hot weather are not harmful to a well-designed and well-installed outdoor ladder, but natural seasonal dust and sand blowing weather may cause excessive wear and tear of suitable equipment and increase maintenance costs, which is also determining the building One of the issues that must be considered before installing an outdoor elevator. All elevator parts exposed to the open air should be properly treated and protected.

Observation elevators can adopt traction drive or hydraulic drive, and the choice depends to a large extent on the lift height of the elevator and the hoistway conditions of the building. Because observation elevators have higher requirements for running quality, they usually adopt variable frequency speed regulation or hydraulic drive. Observation elevators generally do not require high operating speed, because passengers generally want to stay in the car for a while to enjoy the scenery outside the car. The speed of observation elevators should be lower than that of similar objects, as long as the speed is not too slow to affect the vertical traffic in the building.

The car area of ​​observation elevators consists of two parts, namely the passenger area and the viewing area. The passenger area is adjacent to the elevator car door, and the viewing area is usually located at the rear of the car. It is worth noting that the area ratio between the viewing area and the passenger area must be appropriate. The area ratio will increase the difficulty of car balancing. Due to the limitation of the car width in the passenger area, it will extend the time for passengers to enter the car.

The novelty of observation elevators lies in the use of transparent viewing curtain walls in the car viewing area. All personnel engaged in the design, manufacture and installation of observation elevators must be responsible for the glass assembly industry. Before designing observation elevators, designers should consult relevant building codes to understand the requirements for the use of glass materials in elevator cars and hoistways. During the design and installation process, the transparent viewing curtain wall shall not be used as a load-bearing component or structural component. The frame around the transparent viewing curtain wall should be sufficient to withstand all horizontal forces, including the forces that may be generated by elevator passengers, without deformation that affects safety performance.

The car top and car bottom covers must be strong and firm, but they must be light in weight and easy to replace. The design should ensure that the exterior decoration surface of the car is not damaged due to repair work, oil stains or excessive lubricant.

The exposed surface of the elevator hall door and its accessories and all visible parts outside the car should have a smooth, durable, corrosion-resistant and easy-to-clean surface. The surface of the material generally uses anti-corrosion steel or enamel material.

It is possible to provide a safe car top operation and driving place for maintenance personnel so that they can carry out daily equipment maintenance and inspection on the car top. Daily equipment maintenance includes the cleaning of all publicly visible parts and components in the hoistway, such as hall doors and door frame accessories. Observation elevators usually do not have emergency exits on the top of the car. The pit and the bottom layer are protected at the bottom of the elevator. The space under the hoistway should be isolated so that maintenance personnel can safely approach the parts outside the car bottom, perform routine maintenance and cleaning, and replace the external lighting, etc. . The most important thing is to set up a hoistway (pit) fence to prevent passengers or pedestrians from entering it by mistake. The usual practice is to provide the bottom of the hoistway with a transparent curtain wall that is consistent with the elevator equipment decoration, which is part of the elevator civil work.

As a professional elevator lift factory, Webstar Elevator Co., Ltd provides customers with safe and high-quality elevator products.

The hydraulic elevator uses a hydraulic power source to lift

Where will hydraulic elevators be used? The hydraulic elevator is a special kind of elevator, which is lifted and lowered by hydraulic power source. Therefore, its use height is limited, and its use range is also subject to some restrictions, but its safety level is indeed very good. of.

So, where can hydraulic elevators be used? Below, let the elevator manufacturer introduce you to the scope of application of hydraulic elevators.

1. Elevators in hotels, office buildings, libraries, hospitals, laboratories, and low- and medium-rise residential buildings require comfortable ride, low noise, and high reliability.

2. For garages and parking lots, because the car elevator car has large specifications and large output power, the symmetrically arranged double-cylinder hydraulic elevator can make the car in a fairly stable running condition.

3. Old house renovation projects that need to add elevators. Because the renovation of old houses is restricted by the original civil structure, it is the best choice to equip with hydraulic elevators.

4. The addition of an elevator to a classical building cannot destroy its appearance and inner style, so it is also a better plan to use a hydraulic elevator.

5. Shopping malls, restaurants, luxury buildings, the above-mentioned buildings generally use sightseeing elevators, and many sightseeing elevators are driven by hydraulic straight top.

6. On industrial installations such as diving platforms, oil rigs, ships, etc., because these installations generally cannot be equipped with a top-level machine room and have a large load capacity, the advantages of hydraulic elevators are also obvious.

Through the introduction of Webstar Elevator Co.,Ltd., I believe you already know what the scope of application of hydraulic elevators is. If you need to buy or wholesale, please feel free to contact us: China elevator supplier.

The difference between villa home elevators and public elevators

The big difference between villa elevators and public elevators is mainly reflected in load-bearing, speed and lifting height. Compared with public elevators, villas generally have fewer people visiting the elevators, and the height of the buildings is limited.

In the process of users using villas to visit elevators, new requirements are presented, reflecting the expectation that villas can visit elevators faster, reaching a speed of 1 meter per second, but simply considering the speed issue not only touches the comfort and convenience users, But more importantly, the villa visits the elevator for safety reasons, and we cannot blindly seek speed and value safety.

When installing a villa home elevator, users generally consider the overall role of the room. One is to save space as much as possible, and the other is to make it as convenient as possible in use. Therefore, mechanical elevator structures are generally used in homes. The elevator in the villa can be controlled by a computer. This is also a direction to consider the safety of visiting the elevator in the villa.

The villa elevator needs to be combined with the installation environment to confirm:

Regardless of the elevator installation and application, attention should be paid to confirming the scale in combination with the practical installation environment. The specification for confirming the villa elevator scale should be confirmed in conjunction with the villa area and the practical environment of the elevator installation. When confirming the villa plan, it can be combined with the overall decoration plan of the villa.

The villa elevator needs to be decided by the number of people:

The size of the villa elevator should be determined by the number of people using it, because the number of fixed life members in each family is different. When considering devices, provide more convenient conditions for people's lives. Of course, it is also necessary to consider whether there are often foreign personnel in the country. These are all issues that need to be considered when manufacturing elevator scales.

Villa elevators should comply with safe operation specifications:

The size of the villa home elevator should be confirmed in accordance with the safety operation regulations. When installing elevators in villas, it is necessary to pay attention to the electricity consumption required for elevator operations, and it is necessary to pay attention to safety devices. The size of the elevator is directly related to the power consumption of the elevator operation, so people need to pay attention to these problems when installing the elevator.

Structural characteristics of car elevators

The car elevator uses a permanent magnet synchronous traction machine that is energy-saving, environmentally friendly, stable in operation, low in noise, and small in space. Next, the elevator sales editor will introduce to you.

Structural characteristics of car elevators:

1. The structure is simple, no reduction box is needed, the process is simpler, and the volume and weight are reduced, and the utilization rate of the effective space is improved.

2. Low vibration and low noise, especially in the low-speed working area, the advantages are more obvious, the work is stable, and the speed regulation accuracy is high. Geared traction elevator noise is mainly caused by the mechanical vibration and noise of the gearbox and the high-speed rotating motor itself. Since gearless traction does not require a reduction box, the rated speed of the motor is very low, so the vibration and noise of the motor itself are very small, thereby greatly reducing the noise of the entire elevator system.

3. The car elevator realizes gearless speed regulation and does not require the secondary deceleration process, which saves gearbox losses and improves efficiency. After using permanent magnets for excitation, there is no need for excitation current, no excitation loss, and the efficiency of the system can also be improved.

4. The power factor is too high. The energy coefficient can reach more than 0.9.

5. It is safe, reliable and comfortable; it is driven by a permanent magnet synchronous motor, which can effectively prevent the elevator from slipping. At the same time, the motor can also provide sufficient torque at low frequency, low pressure, and low speed to avoid the jitter of the elevator during the start-up retarding process, and improve the comfort of the elevator's braking process.

6. Machine-room-less elevators with various traction modes can be arranged, even if the machine room and small machine room are arranged, they can show a high degree of freedom and flexibility.

Features of hydraulic elevator

A hydraulic elevator refers to an elevator that uses a hydraulic power source to press the oil into the cylinder to make the plunger move in a straight line, directly or indirectly through a wire rope to move the car. A hydraulic elevator is an integrated product of machinery, electricity, electronics, and hydraulics. It consists of the following relatively independent but interrelated systems: pumping station system, hydraulic system, guiding system, car, door system, electrical control system, safety protection system and so on.

Features of hydraulic elevator building structure:

1. There is no need to set up a machine room with high requirements and high cost above the hoistway, and the roof room can be flush with the roof.

2. Flexible machine room settings. The hydraulic transmission system relies on the tubing to transmit power, so the location of the machine room can be set within 20 m from the hoistway, and the machine room occupies an area of ​​only 4 to 5 m².

3. The shaft utilization rate is high. Normally, hydraulic elevators are not equipped with counterweight devices, so the utilization rate of the hoistway area can be improved.

4. The hoistway has low structural strength requirements. Since the vertical loads such as the weight and load of the hydraulic elevator car, all act on the foundation of the hoistway through the hydraulic cylinder, the requirements for the building performance of the walls and top of the hoistway are low.

Characteristics of hydraulic elevator technical performance:

1. Smooth operation and comfortable ride. The hydraulic system transmits the power evenly and smoothly and can realize step-less speed regulation. The elevator running speed curve changes smoothly, so the comfort is better than the speed control elevator.

2. Good safety, high reliability, and easy maintenance. Hydraulic elevators are not only equipped with safety devices that are commonly found in traction elevators.

How to reflect the reliability of hospital bed elevators?

The bed elevator adopts a series of advanced technologies to meet the special requirements of hospitals. While providing safer transportation conditions for patients, it greatly facilitates the work of medical staff and assists them in fulfilling the sacred mission of saving the dead and healing the wounded. The safety of elevators is a comprehensive problem, and many aspects of elevator design, management, maintenance and use will affect the safety of elevators.

However, a qualified elevator designer should choose a reasonable component configuration from the beginning of the elevator design to ensure the safe and reliable operation of the elevator and prevent potential safety hazards. The conventional means are as follows.

(1) The speed limiter and safety gear are used to protect the downward overspeed; the buffer is used to protect the top and bottom.

(2) The use of variable frequency variable voltage speed regulating door machine makes the elevator door switch more stable, lighter and safer, and provides more protection for patients and medical staff.

(3) The light curtain is used as door protection to avoid the impact of the elevator car door on passengers, luggage, carts, etc.

(4) According to regulations: the traction drive elevator shall be equipped with a car upward overspeed protection device. This can be achieved in the following ways:

① Two-way safety gear installed on the car;

②Safety gear installed on the counterweight frame;

③ Acting on the stopping or deceleration device of the wire rope system (suspension rope or compensation rope), such as rope clamp; ④ Acting on the traction sheave or the component closest to the traction sheave and coaxial with the traction sheave.

The use of the rope clamp does not need to change the original elevator structural system, and is a more direct and effective method. Therefore, rope clamps are often used in the development and design of hospital bed elevators, which are installed in the traction frame between the traction sheave and the guide wheel.

How to improve the safety and operating efficiency of hospital elevators?

Hospital elevators are special equipment, and their own characteristics must meet the basic requirements of safety, reliability, comfort, automation, and functionality. At the same time, hospital elevators are more specific. For example, the design and manufacture of hospital bed elevators must ensure the transportation of hospital beds, operating beds, etc., so its car size is much larger than that of ordinary passenger elevators with the same load capacity. The safety factor is, technology and use have special requirements, so its management requirements are higher.

In this regard, the hospital has formulated safe use and management systems, including operating standard procedures, operation and use systems, preventive measures for failures and accidents, emergency plans, sound management files, evaluation of the working status of elevators and escalators, and formulating annual Maintenance plan to ensure the normal use of the elevator.

Effective measures:

1. Separate passenger and cargo

Independently set up a cargo-priority elevator, which can be used by people when there is no cargo. This can prevent other elevators from taking the cargo and making them unavailable, and can also relieve the pressure of the passenger elevator when the cargo is idle.

3. Layered docking

Analyze the flow of people on different floors, and set up each elevator to stop in layers according to the demand, which not only increases the speed of the elevator, satisfies the floors with a large flow of people, but also prevents the waiting staff from stopping all the elevators while waiting, resulting in reduced efficiency.

4. Implement dedicated management

The hospital adds qualified elevator management, full-time operators, and maintenance personnel. The management personnel needs to have corresponding professional certificates and master relevant national laws, regulations, and standards. In view of the particularity of hospital elevators, safe use and management system are formulated and implemented.

5. Daily maintenance

Daily maintenance of the elevators in use. Good maintenance is good medicine to prevent malfunctions. It can not only ensure the stable operation of elevators and escalators in the future but also extend the service life of elevators.

Can't be casual just because it is a freight elevator

Nowadays, elevators are very common, and the utilization rate is very high. At present, almost every office building has several elevators, and there are also freight elevators. Many people have this in mind that freight elevators are mainly for the transportation of goods, so they are not very polite to the goods; here Webstar is here to tell you that no matter what kind of elevator is the same, you can’t be casual just because it is a freight elevator. Talk about the matters needing attention when using freight elevators.

1. Must be lightly opened and lightly closed. (Prevent the door rope from coming out of the slot or breaking the door safety switch)

2. When the elevator is not stuck or malfunctions, do not touch the emergency stop switch. When the emergency stop switch is triggered, the emergency stop light or occupancy light on the elevator panel will light up. Reset the emergency stop switch until the emergency stop light or occupancy light on the elevator panel goes out.

3. The elevator only has all the hall doors. Turn on the phone or use professional OFF correctly. When it is a hall door is not closed, the elevator has abnormal door panel lights.

4. When loading and unloading goods, please place it in the middle of the car (≥5㎝ from the side of the car) to prevent the car from getting stuck.

5. After removing the cargo floor, remove the hall and close it until the call panel or door light goes out to occupy the distance to ensure the normal use of other targets.

6. When the elevator does not stop on this floor, the hall door mechanical lock will be automatically locked. It is not allowed to open the hall door in any way except for maintenance. It is strictly prohibited to short-circuit the safety control switch of the hall door, and open the hall door to let the elevator system run. If it is found that the elevator is open with the hall door, you should immediately stop learning and use according to the operating conditions, turn off the main power of the elevator and all the hall doors to deal with repairs in time.

7. Do not overload, specify on the call panel of elevator operation, the weight of the goods should be less than the carrying capacity.

Work Flow of Hydraulic Freight Elevator

What is the working process of hydraulic freight elevator? Let me introduce you one by one.

(1) Determine the load: According to the required lifting force, transmission speed and installation position, initially select the appropriate elevator model and speed ratio, and initially select the matching drive motor to determine the installation size and spatial location of the entire system.

(2) Determine the working direction: Determine the rotation direction of the input shaft (worm) according to the required working direction of the output shaft. The rotation direction of the worm and the expansion and contraction direction of the lifting screw are similar to the relationship between a gear and a rack. If multiple lifts are used together, the direction of rotation of the commutator should also be paid attention to.

(3) Determine the stroke: After initially selecting the lift stroke according to the working stroke, check the critical bending force of the push rod according to the parameters provided by the lift manufacturer. If the pressure is too large, the screw size needs to be increased. The usual practice is to increase the lift The parameter specification (the screw increases accordingly), and the screw parameter specification can be increased only when the elevator load is sufficient.

(4) Determine the working speed: Check the maximum allowable speed according to the working cycle and load characteristics of the elevator and the elevator parameters provided by the manufacturer. If the speed is too high, you need to select an elevator with large specifications. When the elevator load is sufficient It is also possible to increase only the lead of the screw.

(5) Determine the driving torque.

(5) Determine the driving power.

WEBSTAR serial goods lift adopts the micro-computer control system. It executes the none contact control with the convenient operation and high reliability.

Features of escalators

Most of the appearance of Escalator Supplier and moving walks are made of stainless steel. In order to maintain the gorgeousness and cleanliness of stainless steel parts and prolong the service life of stainless steel parts, the surface of stainless steel must be cleaned and maintained correctly.

The stainless steel components of escalators and moving walks mainly include floor panels, skirts, inner/outer covers, handrail frames, steps, etc. At the same time, according to the special requirements of some customers, sometimes special surface treatment stainless steel may be used, such as Color-plated stainless steel, sandblasted stainless steel, stainless steel surface electrophoresis, etc. In this article, the author mainly introduces the maintenance of stainless steel parts of escalators and moving walks during installation, maintenance during daily use, and some special treatment countermeasures under improper use.

During the installation process of escalators and moving walks, avoid heavy objects hitting or pressing the stainless steel parts, and the protective film cannot be removed. As the stainless steel parts of escalators and moving walks are relatively thin, they must be protected from collisions, squeezing, scratches, etc. during transportation and installation, otherwise the stainless steel parts may be deformed and scratched, affecting their aesthetics.

Try not to remove the protective film on the stainless steel surface before escalators and moving walks are handed over to users. However, the protective film will experience aging, which will leave a paste trace on the surface of the stainless steel plate after aging. Generally speaking, the protective film in the packaged state is effective for a certain period of time at room temperature and a certain humidity. However, due to different specific conditions, such as wind and sun, heat, pressure, etc., the film’s service life cannot be guaranteed. , So it is necessary to determine the time to tear off the film according to the specific situation, so as not to leave mushy marks. After the protective film is removed, the stainless steel surface of China escalator company must be cleaned and maintained correctly.

The current escalator and the previous escalator

The steps of the early Escalator Supplier were made of wood. Since the spiral escalator was fired at the Underground Railway Station in London in 1987, most of the wooden steps still used have been changed to metal. The steps of modern escalators are made of metal, and below each step is a triangular bracket. There are two high and low shafts at the bottom of the bracket, and there are wheels on the shaft. The two wheels on each side walk on different tracks, and the steps are kept level by changing the distance between the tracks. The wheels above each step support are connected by hinges. A motor is installed under the comb plate at the top of the escalator to drive the hinge to move the steps. When the steps reach the end of the escalator, they will first turn into a horizontal row for passengers to leave, then pass through the comb board, then turn to the bottom, and walk in the other direction, forming an endless circle. The side panels of some new escalators are made of glass, so this mechanical structure can be clearly seen. As for the handrails on both sides, they are made of rubber and driven by wheels, and the speed must be consistent with the steps.

Most of the escalators are straight. In 1985, Japan's Mitsubishi Electric invented the curved, spiral-shaped escalator for the first time. In addition to saving space, the spiral escalator is also very artistic. In addition, some escalators can be turned back to level in the middle section. This can reduce passengers' fear of height when using very long escalators, and it can also be more flexible with the building.

When many people use escalators, in addition to letting the escalator drive, they also use their legs to walk on the steps to save time. Therefore, when using an escalator, the standing passengers should lean on the same side of the step and let out the other side of the step for people walking. However, different regions have different conventions about which side you should stand on. For example, the London Underground Railway, the Washington Underground Railway, the Kansai Railway in Japan, and the Taipei MRT require standing passengers to stand to the right; but Tokyo, Japan requires passengers to stand on the left. The Montreal subway has no rules, because they believe that passengers should not walk on escalators at all.

When using an escalator, you should also be careful to hold the handrails tightly, do not stand on the edge of the step, do not stick your head or hands out of the ladder, otherwise you may hit the ceiling or adjacent escalators, do not run and play, do not use the escalator to carry goods. Strollers, cargo carts, etc. should use elevators. Passengers who use wheels or crutches should use elevator supplier as much as possible. Escalators will have emergency stop buttons for use in accidents.
