What is the reason for the deviation of escalator steps?
What is the reason for the deviation of escalator steps?
The escalator consists of steps traction chains, step guide rail system, drive device, tension device, and handrail device and metal structure. The structure includes: steps, kick plate, bracket and auxiliary wheel. Escalator is continuous work, therefore, in the stream of people concentrated in public places, shops, railway stations, airports, docks, the place such as buildings and underground railway station, to transport a large number of people in a shorter time, using the escalator has more advantageous than using intermittent working elevator.
The steps are integral and modular. The integral die casting is made of aluminum alloy with high precision, light weight and high processing speed. The modular echelon is composed of steps, kicking plate, supporting frame and other parts, with large weight and poor precision. It is a product of small die-casting capacity and is gradually replaced by integral echelon.
The steps move horizontally at the passenger entrance (for passengers to get on the stairs) and gradually form the steps. The steps fade away near the exit and the steps move horizontally again. These movements are realized by the steps of the main wheel and the auxiliary wheel respectively walking along different steps of the guide way.
Under the escalator room has two springs, is for adjusting the escalator cascade running deviation device, if can’t adjust well, that’s different cascade big chain long, need to change the big chains.
The escalator is generally inclined. A pedestrian standing on one end of an escalator will be automatically taken to the other end of the escalator and the steps will remain level all the way. Escalator step has with cascade synchronous moving in on both sides armrest, fu grip for users. Escalators can always walk in one direction, but most can be controlled by managers according to the needs of time, people and so on. Another type of pedestrian conveyance similar to escalators is the automatic walkway. The main difference between the two is that there are no steps on the automatic pedestrian path. Most only walk on the flat ground, or lean slightly.
The escalator consists of a stairway (variable plate conveyor) and an arm rest (deformed belt conveyor) on both sides. Its main components are cascade, traction chain and sprocket, guide rail system, the main drive system (including motor, speed reducer, brake, and the middle transmission links, etc.) drives main shaft, step and tension device, skeleton, comb plate, escalator handrail system and electrical system, etc. The staircase gradually forms a staircase after horizontal movement towards the passenger entrance (facilitating passengers to ascend the stairs). The steps close to the entrance gradually disappear and the steps move horizontally again. These movements are realized by the steps of the main wheel and the auxiliary wheel respectively walking along different steps of the guide way.

What is the escalator anti-climbing device (Anti-climb Barriers)?
When the escalator is more than 12.5 cm adjacent to the wall, it should be on the escalator or automatic.
A blocking device installed at the upper and lower end of a sidewalk.
Generally, the escalator anti-climbing device on the market is mostly made of acrylic material, and its characteristics are as follows:
- The heat deformation temperature of ordinary acrylic sheets is about 100 degrees, and the continuous use temperature should not be higher than 90 degrees.
- Acrylic sheets are easy to generate static electricity and absorb dust. When cleaning with soft cotton cloth dip 1% soap water can be wiped.
- The surface hardness of acrylic sheets is equivalent to aluminum materials. When used or processed, please be careful to avoid surface scratches. If you get scratched,
The original glossy surface can be restored by polishing.
Installation necessity
In public elevators, there are no shortages of children chasing after play. Although many beside the escalators are “forbidden climbing play”, “children must be under adult supervision on” logo, but the installation of the elevator armrests prevent climbing, will also reduce the risk of accidents.
So to go against the wall adjacent to more than 12.5cm, on escalators or sidewalks, bottom department shall install block device, to prevent people from entering the outer cover plate area, thus fall accident, etc.
Method of use
If there is a risk of a person falling, appropriate measures should be taken to prevent the person from climbing onto the outside of the handrail device. In order to ensure this, escalators and moving sidewalks outside cover plate should be installed on the fortification climb the device (see right-hand chart), climbing device located above ground plane h9 (1000 + 50 mm), lower fellowship with outer cover plate, parallel to the outer cover plate on the direction of extension of l5 should not be less than 1000 mm in length, and shall ensure that within the scope of this length without stepping on foot.
How to avoid elevator car door failure?
The failure of elevator door system accounts for a large proportion of the total failure of elevator, among which the door mechanism is the most frequently running system in the work of elevator, which is directly related to the safe and reliable operation of elevator. The failure rate of car door system also accounts for a considerable proportion in the failure rate of door system. The main reason is that the installation technology of door system is not up to the design requirement. The interpretation of the car door below is shared.
- The door opener, car door, safety security sensor, and the installation of the door knife have been completed by the installation team at the time of maintenance.
- The adjustment of car door is the premise of door system adjustment. Only after the door is adjusted, will the door be calibrated.
- First remove dust from the door with a pair of fan, and then grind the track of the door with more than 300# sandpaper to ensure the flexible operation of the door.
- The door must be adjusted to:
- The distance between the door plate and the floor sill is 4mm;
- The distance between the door and the front wall of the car is 4-6mm (not too small). Check method is to use just ruler on two pieces of door plank up and down side, whether it is balance.
- The front and side of the door must be vertical to ensure that the door is properly sewn when it closed, meanwhile when opened; it joined to the front of the car. After adjusting the car door, you can open and close the door manually. The whole switch process should be easy and smooth.
- Adjust the security sensor and light curtain. When the contact plate is extended, the contact plate’s protrusion is suitable for 30mm to 50mm, and the same amount of two contacts is used. The light curtain should be even, and no abnormal trigger should occur during the rapid opening and closing process, especially for the rear light curtain to keep clean.
- Adjust the opening knife: step 1: make sure the distance between the door knife and the floor sill of the hall door is 7mm, and ensure the vertical direction; Step 2: determine the distance between the blade of the door knife and the decoupling roller of the door lock of the hall door is about 7mm. Check running elevator to observe all the way, depends on the clearance of most hall door, can be in a small range on the left, right, right amount translation car door assembly (this method is not applicable to double synchronous door knife of double folding door such as TD3200 car elevator door machine); Step 3: the two surfaces of the door knife blade, namely the one of the rollers, must be vertical. Step 4: check that when driving the door, the blade should not make abnormal sound.
- The speed of opening and closing shall be adjusted when the door of the sedan chair drives the door of the hall. The speed shall be controlled at about.070m/s. The speed of opening and closing doors should be gentle according to the elevator’s different acceleration and deceleration.
What is the function of escalator apron board safety device?
The micro-switch of apron plate is a safety-protection micro-switch after the apron plate. When the escalator works normally, there is a certain gap between the apron board and the step. The single side is no more than 4mmand the sum of both sides is no more than 7mm. In order to guarantee the safety of the passengers, the apron board on the back of the pack of c-shaped steel, c-shaped steel distance setting switch, when foreign body into the apron board and the gaps between the cascade, apron plate deformation, c-shaped steel also move, after reaching a certain position, touch attack switch, then escalator stop running immediately.
The sensitivity of the device depends on the rigidity of the apron board. Too rigid apron plate is not easy to deform, cannot touch the micro switch, does not play a safe protection role; the rigidity is too small and the phenomenon of frequent parking will bring troubles to the normal operation of escalators. In addition, the micro switch is not generally set in the whole process, and it is only installed at the exit entrance of the escalator. Therefore, there are safety risks in the area other than the micro switch.
Filling device
A plastic and dry lubricant filled plate is arranged on both sides of the step and its shape matches the step. Fill plate by a spring or tie rod to keep its position and the entire range of the escalators and apron board contact, filled with escalators between apron board and cascade on both sides of the gap and its safety protective effect is obvious. The device, the filling plate contact with apron board is a kind of dry friction, easy to wear apron board Teflon coating and furnish the filler plate larger workload, so rarely used in our country.
Anti- clamping device
This is an economical and practical anti-clamping device, which compresses the rubber into a D section and fixes it to the apron board. Because the friction coefficient of rubber material is big, once the passenger meets the feeling that can be pulled again, can leave both ends of the step automatically, have safe protection effect.
For escalators with such clamping devices, rubber strips should not have sharp edges and should be checked frequently, as they can also bring danger to passengers if they leave apron boards.
Safety brush clamping device
Installed on the apron board safety brush, brush the clamp device is composed of base and brush, base without sharp edges, and can easily remove brush is soft and has a certain hardness, it does not hurt the clothing, meet the brush in the passengers’ shoes automatically after recovery.
The safety protection effect of safety brush anti-clamp device is obvious.

Why does the elevator have a overspeed governor?
Elevator Overspeed governor （Elevator OverSpeed limiter） is one of the safety control components of elevator safety protection system. When the elevator in running ,no matter what the speed governor in the car or the risk of falling or other situations of safety protection devices do not work, safety gear speed governor and linkage will start to work and make the elevator car stop running, to ensure the safety of the elevator.
- Installation location
The speed governor is generally located in the elevator machine room. According to the requirements of the installation plan, it is generally installed on the floor of the machine room. However the speed governor also can be directly installed on the bearing beam .The specific position of the speed governor is determined according to the construction drawing and the position of the car and guide rail after adjustment.
- Technical requirements
- We should pay attention to the speed governor wheel vertical degree of deviation should not be more than 0.5 mm, speed governor wire rope should be aligned with room reserved hole center, the error is not more than 0.5 mm, governor rope groove center and tension pulley rope groove center must be in the same vertical plane. The car will be two rope to the connecting hole, two connecting holes should be on the same vertical line after the connection completed.
- According to the requirements of the installation plan, the position deviation of the speed governor should not be greater than 3mm.
- The distance between the rope and the guide rail of the speed governor device should meet the requirements of the installation plan.
- The tension of the tension device on each branch of the rope shall not be less than 150N.
- Speed governor switch and tension wheel switch shall ensure that the control loop can be cut off quickly and reliably when the rope breaks off, falls off, the rope clamp is unhooked or the speed governor is in action.
- Notes
- The action direction of the speed governor should be consistent with the descending direction of the car to ensure the safety clamp works.
- The wire rope of speed governor shall not be rubbed or contacted with the clamping pliers during normal operation.
- The steel wire rope of speed governor shall not have any dead bend and a rope sleeve shall be installed at the connection with the cage pull rod and the rope head shall be firmly fastened with a rope clamp
- Restrictions
The speed governor must be starting to work before the car speed exceeds 115%.
1) For instantaneous safety gear, the speed governor of 0.80m/s (except roller type).
2) For roller type instantaneous safety gear, the speed governor of 1.0 m/s.
3) for safety gear with buffer effect and for progressive safety gear with rated speed governor not exceeding 1.0 m/s, 1.5 m/s.
4) for progressive security safety gear with rated speed governor over 1.0 m/s, the speed governor of 1.25 *v+ 0.25 /v.
The speed governor is a safety device, so the manufacturer should evaluate the product in accordance with appendix Fo4 of the en81-1/2 standard before it is released.
