Problems solved by technology
Among them, the traditional handrail transmission in the electric escalator is to move forward by continuously pulling the ring-shaped handrail belt. During the process of pulling the handrail belt, the handrail belt will produce a downward force on the handrail belt due to its own gravity and when the pedestrians hold it. Pressure, so that there is a greater pressure between the handrail and the lower fixed track, so that there is a greater frictional resistance between the handrail and the track, so that the handrail needs a greater driving force when it is driven, and at the same time a larger The frictional resistance makes the handrail easy to be worn and has a short service life

Embodiment Construction
[0016] Below in conjunction with accompanying drawing and embodiment the present invention is further described:
[0017] Such as figure 1 , figure 2 and image 3 As shown in the embodiment, the electric escalator handrail transmission structure includes a fixed rail 1, a handrail belt 2, and a transmission wheel 3, and the handrail belt 2 is wound and passed through the fixed rail 1 and the transmission wheel 3; the fixed rail 1 The upper part is designed with edges 12 protruding vertically to both sides. The handrail 2 is wrapped outside the edge 12 on the upper part of the fixed track 1. The edge of the fixed track 1 is made of a magnetic material. The upper part of the edge 12 of the track magnetic block 11 is arranged in a straight line. The direction of the magnetic force line of the track magnetic block 11 is perpendicular to the upper surface of the upper edge of the fixed track 1. The magnetic poles of the track magnetic block 11 are facing the same direction. The ...

The invention provides a handrail transmission structure of an escalator. The handrail transmission structure of the escalator comprises a fixed track, a handrail belt and a transmission wheel, and the handrail belt is wound on the fixed track and the transmission wheel to pass. Edges vertically stretching out of the two sides are designed on the upper portion of the fixed track, the handrail belt is wrapped outside the edges on the upper portion of the fixed track, track magnetic blocks are distributed on the fixed track, belt magnetic blocks are fixed to the positions, corresponding to the track magnetic blocks, of the lower portion of the handrail belt, and same-magnetism magnetic poles of the belt magnetic blocks and the track magnetic blocks are opposite. In the using process of the handrail transmission structure of the escalator, the handrail belt can be hung in the air relative to the upper portion of the fixed track, friction resistance is very small, driving power in use is very small, abrasion of the handrail belt is small due to the small friction force of the handrail belt, and service life is longer.
Description
Technical field [0001] The invention belongs to the technical field of elevator equipment, and in particular relates to a transmission structure of an electric escalator handrail. Background technique [0002] Escalator, also known as escalator, or automatic pedestrian elevator, escalator, etc., is a means of transportation that transports pedestrians in the form of a conveyor belt. Escalators are generally inclined. Pedestrians stand on the self-propelled steps at one end of the escalator, and they will be automatically taken to the other end of the escalator, and the steps will be kept level all the way. The escalator has handrails on both sides that move synchronously with the steps for users to hold on to. [0003] The electric escalator mainly has two moving parts when in use, one is the inclined upward movement of the steps, and the other is the belt type friction transmission of the handrail. Among them, the traditional handrail transmission in the electric escalat...
