Abstract

The invention discloses a driving device for an escalator or a moving sidewalk. The driving device comprises a motor, a brake, a reduction box, a step chain driving wheel, a hand strap driving wheel and an additional braking wheel which are pre-integrated and are in sequential transmission; the step chain driving wheel, the hand strap driving wheel and the output end of the reduction box of the driving device are directly connected for transmission, and thus coaxial direct driving of a step or a pedal and a hand strap is achieved; and the driving device is mounted in the operation trajectory of the step or the pedal, one side of the driving device is mounted on a truss driving rod through bearing seats at the two ends, and the other side of the driving device is connected with a truss mainmachine base. The driving device for the escalator or the moving sidewalk does not adopt traditional chain transmission, the factors such as unsafety and difficult maintenance of a traditional driving device are overcome, integration of hand strap and step or pedal driving is achieved, the transmission efficiency is improved, the civil engineering space is saved, the structure is safer and more reliable, multi-stage driving is adopted, and thus the product application range is expanded.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to a driving device for an escalator or a moving walk. Background technique [0002] The drive of escalators or moving walks mainly includes the main drive for driving the steps and the handrail drive for driving the handrail belt. Traditional escalators or moving walks widely used drive structure, such as figure 1 As shown, the drive device includes: a drive host 3, a main drive chain 5, a main drive 2, a handrail drive chain 6, and a handrail drive 1. The drive main engine 3 installed in the head machine room on the truss 4 passes through its output small sprocket, and the main drive chain 5 is connected with the large sprocket 18 on the main drive to drive the main drive shaft to run, and the step chain on the main drive shaft drives The wheel 8 drives the step or pedal chain to realize the operation of the steps or pedals of the escalator or moving walk; then the handrail d...
