Abstract
The utility model discloses a control device facilitating step chain stretching and retracting and an escalator for teaching, belongs to the technical field of escalator detection, and is used for controlling a chain wheel disc and a step chain of the escalator for teaching to deviate so as to trigger a travel switch to achieve sudden stop. A limiting hole is formed in a mounting side plate, and a mounting bearing is slidably arranged in the limiting hole; the pushing plate is connected with an outer ring of the mounting bearing, the supporting plate is arranged on the mounting side plate and located beside the limiting hole, the first end of the adjusting part is used for penetrating through a screw hole preset in the supporting plate and then abutting against the supporting plate, and the adjusting part is used for being screwed to abut against and push the supporting plate through the first end of the adjusting part. And the mounting bearing, the wheel disc mounting shaft and the chain wheel disc are pushed to deviate, so that the travel switch is triggered. The installation bearing, the wheel disc installation shaft, the chain wheel disc and the step chain are pushed by the adjusting part to integrally perform offset motion, so that the travel switch is triggered, the step fracture fault is simulated, and the function of the teaching equipment is supplemented.
