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.
