Description

Technical Field

[0001] The present invention relates to the technical field of underground coal mine auxiliary equipment, and in particular to a lifting device for underground coal mines. Background Art

[0002] At present, the main form of transportation underground in coal mines is still rail transportation. In the process of material transfer, material loading and unloading, equipment installation and removal, the backward method of manual handling and hand-pulling and shoulder-carrying is still commonly used. For heavier materials, they are lifted by drilling root hanging points and using wire rope buckles, hand winches, etc. Not only is the material loading and unloading efficiency low and the construction period long, but the labor intensity of workers is also high and the safety risks are high.

[0003] In underground coal mines, materials are generally stored in the transfer yard in the main tunnel and the temporary yard in the mining area. Since the transfer yard in the main tunnel is in a fixed position, a pneumatic hoist or a crane can be installed to assist in loading and unloading. However, the location and position of the temporary yard in the mining area will change frequently due to the limitations of the tunnel conditions in the mining area and the installation and removal of the mining face. The installation and removal of the pneumatic hoist will be labor-intensive and time-consuming, which will greatly reduce work efficiency and increase the workload of personnel.
