[0002] Belt conveyor is a friction-driven mechanical equipment, mainly used for continuous transportation of materials. Belt conveyor can transport materials from the feeding point to the unloading point on a certain conveying line, forming a continuous material transportation process. It can transport both bulk materials and pieced items. In addition, belt conveyor can also cooperate with the process in the production process of industrial enterprises to form a rhythmic assembly line transportation line.

[0003] When existing thermal power plants use belt conveyors to transport coal, the belt conveyors are often damaged by iron objects in the incoming coal, and conveyor belt tearing occurs from time to time. Longitudinal tearing of the conveyor belt is an accident with the highest probability of the conveyor belt being damaged by iron objects. In mild cases, the surface of the conveyor belt is damaged. In severe cases, the entire conveyor belt is cracked longitudinally, resulting in serious damage. Therefore, the present application proposes an anti-tear mechanism for the coal conveying belt of a thermal power plant to solve the above technical problems. Utility Model Content

After pulling the limit rod and pulling the limit rod out of the limit groove, the connecting sleeve can be moved to adjust the position of the infrared transmitter, so that the monitoring effect of the conveyor belt is better, which can reduce the damage degree of the conveyor belt and thus reduce the loss cost.
