The invention relates to the field of hydraulic hoisting machines, in particular to a hydraulic hoisting machine for an underground coal mine. The hydraulic hoisting machine for the underground coal mine comprises a hoisting beam, wherein one end of the hoisting beam is connected with a hoisting hook. The hydraulic hoisting machine for the underground coal mine further comprises a three-leg support, a base disc, a single hydraulic column, a lower supporting disc and a lower rotating disc. The three-leg support is arranged on a roadway base plate in a supported mode. The base disc is fixed to the bottom end of the interior of the three-leg support, and an opening of the base disc is upward. The bottom end of a cylinder body of the single hydraulic column is installed in the base disc in a sleeving mode, and the upper portion of the single hydraulic column penetrates through the top of the three-leg support. The lower supporting disc is connected to the cylinder body of the single hydraulic column through bolts, clamped on the cylinder body of the single hydraulic column and fixed to the top of the three-leg support, and comprises two semicircular rings. The lower rotating disc is arranged on the upper side of the lower supporting disc and movably installed on the outer side of the cylinder body of the single hydraulic column in a sleeving mode. The hydraulic hoisting machine for the underground coal mine is reasonable in structure and good in using effect, and easy and convenient to assemble, can effectively solve the problem that manpower is consumed when a machine is disassembled and assembled in a narrow space, and improves the disassembly and assembly progress.
