[0002] In coal mining operations, coal mine transport vehicle as the key equipment of coal transportation, its performance directly affects the efficiency and safety of coal mining. The traditional coal mine transport vehicle in the connection mode of coal storage frame and vehicle body, more using bolt fastening or welding and other fixed mode. Bolt fastening needs to spend a lot of time for installation and disassembly, and in the bumpy environment of underground, bolt is easy to loosen or even fall off, there is a security risk; although the welding method is firm connection, but the coal storage frame is difficult to replace after damage, resulting in a substantial increase in equipment maintenance cost.

[0003] In addition, the traditional coal mine transport vehicle lacks effective dustproof measures in the transportation process, and the flying coal dust in the underground is easy to enter the internal transmission components of the vehicle body, which accelerates the wear of the components and reduces the service life of the equipment. Frequent fault maintenance also seriously affects the efficiency of coal transportation. At the same time, the existing coal mine transport vehicle has poor control flexibility, and it is difficult to realize rapid steering and precise movement in narrow and winding coal mine roadway, which limits the development of transportation operation.

[0004] In order to solve the above problems, it is urgent to develop a coal mine transport vehicle which is convenient to install, stable in transportation and flexible in control, so as to improve the efficiency and safety of coal mining and transportation operation, reduce the equipment maintenance cost and meet the needs of modern coal mine production.
