Description

Technical Field

[0001] The utility model relates to the technical field of automatic escalators, in particular to a driving wheel of a synchronous handrail belt. Background Art

[0002] An escalator is a common mechanical transportation device used to transport people inside and outside buildings. It is particularly suitable for places that require frequent and large-scale movement of people, such as shopping malls, airports, subway stations, etc. The escalator is driven by electricity and moves continuously in an inclined direction, providing people with a convenient, safe and efficient way to go up and down floors. The handrail is an important component of the escalator system. The handrail can provide a stable support point for passengers on the escalator. Passengers can hold the handrail to maintain balance and stability, reduce the risk of falling, and the moving speed of the handrail is consistent with the steps. Passengers You can adjust your pace and posture according to the movement direction and speed of the handrail to ensure smooth going up and down the escalator. In order to improve the synchronization and stability of the handrail, a wedge-groove synchronous tooth handrail has appeared in the prior art. When this handrail is used in conjunction with a handrail driving wheel with a wedge-shaped groove, it can ensure the stable movement of the handrail and synchronized operation with the steps. However, the drive of the wedge-groove handrail itself requires a handrail driving wheel with a wedge-shaped groove. The process of machining synchronous tooth grooves on the surface of the driving wheel is very complicated, and also has high requirements for machining accuracy, which results in the wedge-groove handrail being unable to be widely used.

[0010] Through the above technical solution, the second handrail belt is a common universal handrail belt. By setting the wedge-shaped bar in the second handrail belt in the annular groove, the driving force is improved, ensuring that the common universal handrail belt can also be stably driven, so that the driving wheel of the synchronous handrail belt proposed in the utility model is not only suitable for the wedge-shaped groove synchronous tooth handrail belt, but also for the common universal handrail belt.

[0011] The beneficial effects of the utility model are as follows:

[0012] When the driving wheel of the synchronous handrail belt proposed by the utility model is used to drive the wedge groove synchronous tooth handrail belt, the synchronous teeth of the wedge groove synchronous tooth handrail belt can cooperate with the cylindrical pin, the synchronous teeth will be in the meshing groove, and the cylindrical pin will be in the wedge groove, so that the wheel body can drive the wedge groove synchronous tooth handrail belt when rotating, ensuring that the wedge groove synchronous tooth handrail belt can play its original role, so that the driving of the wedge groove synchronous tooth handrail belt does not need to use a handrail belt driving wheel with a wedge groove, which has very complex process and high processing accuracy requirements, so that the wedge groove synchronous tooth handrail belt can be more widely used, and the driving wheel of the synchronous handrail belt proposed by the utility model is not only suitable for wedge groove synchronous tooth handrail belts, but also can be applied to common general handrail belts, and has strong applicability.
