Self-advancing tail device of underground coal mine belt conveyor

The invention relates to a self-advancing tail device of an underground coal mine belt conveyor. For the condition that the belt conveyor is hard to move in a narrow underground roadway of a coal mine, the design that a mechanical structure and electrical control are combined is adopted, and a stepping tailstock is provided with a front end, a rear end, a chassis assembly, a deviation regulating mechanism, a hydraulic mechanism, a pushing oil cylinder, a lifting oil cylinder and a supporting oil cylinder, so that the belt conveyor moves through the self-advancing tail device, and the moving speed and safety of the belt conveyor are improved. The self-advancing tail device of the underground coal mine belt conveyor is advanced in design, compact in structure, capable of being remotely operated, safe, stable, reliable and quite advanced.
