Cover plate structure of winding motor fan housing for hoisting and mounting and dismounting method of cover plate structure

The invention discloses a fan housing cover plate structure of a winding motor for hoisting and a mounting and dismounting method of the fan housing cover plate structure, and relates to the technical field of winding rotor motors for hoisting. The winding motor for hoisting solves the problems that when a carbon block of an existing winding motor for hoisting is replaced, a fan cover needs to be integrally detached, or bolts are prone to falling off and losing when a fan cover plate fixed through the bolts is detached, the maintenance efficiency of the motor is reduced, and meanwhile the maintenance cost of the motor is reduced. A fan housing cover plate is arranged on the upper portion of an operation through hole of the fan housing in a buckled mode, the two ends of the fan housing cover plate are in lap joint with the fan housing on the two sides of the operation through hole, the lower connecting sections of a plurality of connecting pieces sequentially penetrate through the narrow side of a convex hole
