[0002] With the progress of the times and the development of the social economy, the level of mechanization of coal mine equipment has been continuously improved, the advance speed of fully mechanized mining faces in mines is getting faster and faster, and material handling operations at the working face are becoming more and more frequent. At present, traditional underground material handling methods still rely on winch traction or manual assistance. The traction force is small, the cycle operation is time-consuming, and the handling process is easily restricted by the roadway conditions, resulting in low efficiency, high labor intensity for workers, and low safety factor. Secondly, underground roadways are narrow and the ground is uneven. Traditional handling equipment has a single function and cumbersome procedures, which greatly increases the auxiliary time in the operation process. Moreover, it has poor adaptability to more complex roadways, which greatly restricts its application scope. Summary of the Invention

[0003] The purpose of this invention is to propose an intelligent explosion-proof diesel engine tracked transport vehicle to address the problems existing in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An intelligent explosion-proof diesel engine tracked transport vehicle consists of a frame assembly, a cab, a loading section, an intelligent system, an explosion-proof power system, a hydraulic system, and an electrical system. The frame assembly is mounted on a mounting plate on the inner side of the front end of the loading section. The cab is fixed to the left side of the frame assembly. The intelligent system is installed on the upper part of the connecting frame on the left side of the frame assembly.
