Abstract

The invention discloses a handrail belt driving device of a spiral escalator. The handrail belt driving device comprises a driving main engine, a step driving main shaft, a driving chain connected with the step driving main shaft and the driving main engine, handrail shafts used for driving the handrail belts to move, and a transition chain which drives the handrail shafts and the step driving main shaft to rotate synchronously, wherein the handrail shafts at least comprises an outer side handrail shaft close to the outer side handrail belt, an inner side handrail shaft close to the inner sidehandrail belt, and a connecting shaft which connects the outer side handrail shaft with the inner side handrail shaft, the joint between the outer side handrail shaft and the connecting shaft is of auniversal structure, the joint between the inner side handrail shaft and the connecting shaft is of a universal structure, one side, close to the outer side handrail belt, of the outer side handrailshaft is provided with an outer side handrail belt driving mechanism, and one side, close to the inner side handrail belt, of the inner side handrail shaft is provided with an inner side handrail beltdriving mechanism. The handrail belt driving device can meet the special requirements that the handrail belts can be laterally bent with same angular velocity and different linear speed at two sides.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to a handrail drive device of a spiral escalator. Background technique [0002] With the development and progress of society, escalators have been widely used and become an indispensable equipment for people's convenient life. But the current escalators are basically linear escalators. [0003] The working mode and functional components of the spiral escalator are similar to those of the linear escalator. The spiral escalator can provide passengers with ascending or descending services. There are handrails on the left and right sides of the steps for passengers to grasp. Both the handrails and the steps are It runs on a spiral trajectory. [0004] As far as the current ordinary linear escalator is concerned, the handrail belt drive generally adopts the method of driving the handrail shaft by the sprocket on the main shaft of the ladder drive through the chain, thereby driving t...
