[0002] In the comprehensive mechanized supporting equipment of the coal mine excavation working face, belt conveyors are usually used to transport coal. Due to the large size and weight of the DSJ120 belt rack, the belt rack is often installed centrally and the belt is laid centrally. With the changes and development of the coal mine recovery tunnel excavation process, the DSJ120 belt rack is also used in the excavation working face. As the excavation working face continues to move forward, the belt rack needs to be extended forward regularly. Since the spacing between the upper and lower belts of the DSJ120 belt rack is small, when installing the upper bracket and the upper supporting wheel of the belt, the construction space is small, the construction is difficult and there are safety risks. In order to solve the problem of small construction space for extending the DSJ120 belt rack, the prior art uses a lever to pry up and lift the belt at the end of the middle frame of the belt conveyor. However, in the above-mentioned prior art, the effect of using a lever to pry up the upper belt is poor, and the lever is easy to scratch the belt, and there is a problem that the lever is easy to slip, which takes up a lot of manpower and takes a long time.

[0003] Therefore, how to provide an efficient and safe lifting belt device is a technical problem that technicians in this field currently need to solve. Utility Model Content
