AI Technical Summary
Because the track dimensions of existing escalator turntables are fixed, there are gaps in the movement when the steps turn, and the step wheels hitting the turntable generate a lot of noise, which affects the environment.
Design an escalator turntable that uses a through groove and slider on the inner track. The slider cooperates with the pressure guard plate and eliminates movement gaps by adapting to the supporting force of the components and springs, thereby reducing noise.
It effectively reduces noise during step reversal, reduces wear on step wheels, and extends the service life of escalators and turntables.

[0002] Escalators, also known as moving walkways, are a type of transportation that uses a conveyor belt to move people. Escalators are generally inclined; pedestrians stand on the automatically moving steps at one end and are automatically carried to the other end, with the steps remaining horizontal throughout the journey. Compared to elevators, escalators occupy more space and their vertical movement is relatively slow. However, because escalators move continuously, unlike elevators where passengers have to wait for the car to arrive, their total passenger capacity is much higher. Therefore, they are commonly seen in high-traffic areas such as shopping malls and subways.
[0003] In existing escalator turntables, the dimensions of the track on the turntable are fixed. When the steps rotate, due to the movement gap, the step wheels at the bottom of the steps will hit the turntable, resulting in a lot of noise during the step rotation process, which has a negative impact on the environment. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the Invention
[0004] The purpose of this utility model is to provide a turntable for escalators to solve the problem mentioned in the background art, where the size of the track on the turntable of the existing escalator is fixed, and when the steps rotate, due to the movement gap, the step wheels at the bottom of the steps will hit the turntable, resulting in a lot of noise during the step rotation process and having a negative impact on the environment.
