As a vertical transportation tool, elevators are becoming more and more common and closely related to people's lives. However, the working principle of elevators has not changed for more than a hundred years. The two ends of the traction rope are still connected to the car and the counterweight device respectively. The traction rope is wound on the traction wheel and the guide wheel. The traction motor drives the traction wheel to rotate after the speed is changed by the reducer. The friction between the traction rope and the traction wheel generates traction to realize the lifting and lowering movement of the car and the counterweight to achieve the purpose of transportation.

[0003] The intelligent dynamic balancing device for elevators described in the patent application with reference publication number CN109019275A comprises a counterweight support and a car, wherein the counterweight support and the car are connected by a traction rope, and the traction rope is wound around a guide wheel and a traction wheel, wherein the guide wheel is located above the counterweight support, and the traction wheel is located above the car, and the traction wheel is provided with a traction rope embedding groove, and resistance reduction areas are arranged at equal distances on the traction rope embedding groove, and a circular hole groove is arranged inside the traction rope embedding groove located in the resistance reduction area, and the traction wheel is provided with a sliding ball for movement in the resistance reduction area, and the sliding ball protrudes from the circular hole groove.

Over time, gaps are likely to occur in the internal components of the car, and even angle friction may occur at a certain position of the traction mechanism of the car, thereby increasing safety hazards.
