Description

technical field [0001] The invention relates to the technical field of escalator equipment, in particular to a pedal transmission mechanism of an escalator gear mechanism control device. It belongs to B66B1 / 24, B66B11 / 00, B66B5 / 00 in the IPC classification system. Background technique [0002] At present, electric escalators, also known as escalators, or automatic pedestrian elevators, escalators, and escalators, are a type of escalator with a circular running ladder, which is suitable for fixed electric drive equipment that transports passengers upward or downward. The escalator is generally placed obliquely. Pedestrians stand at one end of the escalator and walk on the self-propelled steps, and they will be automatically taken to the other end of the escalator. The user holds the escalator, and the escalator can always walk in one direction, but most escalators can be controlled by the manager according to the needs of time, flow of people, etc., another pedestrian transp...
