Description

Technical Field

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. The coal seams of most coal mines in my country are far away from the surface, so open-pit mining cannot be used. Therefore, most coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities.

Coal mine electromechanical equipment for underground mining mainly includes ventilation equipment, compressed air equipment, pressure equipment, drainage equipment, excavation equipment, transportation equipment, power supply and electrical equipment, safety monitoring and control, and gas extraction equipment. When coal mines are mined, it is often necessary to use coal mine electromechanical equipment devices in the coal mining process. When coal mine electromechanical equipment is transported underground for installation and use, a lifting device is required. The electromechanical equipment required in the coal mining process is transported underground or transported from underground to the ground by a lifting device, but the existing coal mine electromechanical equipment lifting device is not convenient to adjust the lifting width according to the size of the electromechanical equipment, resulting in poor stability of the electromechanical equipment during the lifting process and easy damage.
