[0002] Mining electromechanical equipment refers to the electrical and mechanical equipment and systems involved in the mining process, including the mechanical, electrical, and automated equipment used in all stages of mining, such as extraction, transportation, ventilation, drainage, hoisting, crushing, and screening. The stability and reliability of this equipment are crucial for mine production safety. It involves a wide variety of equipment, encompassing various electrical control systems and mechanical operating systems. Mining electromechanical equipment is large, heavy, and complex to install, and is typically located deep within mines or in harsh working environments. Lifting can efficiently and safely transport and install this heavy equipment.

[0003] For example, a hoisting device suitable for mining electromechanical equipment, disclosed in CN223239607U, includes a gantry frame. The gantry frame includes two support columns, with movable columns fixedly mounted on the top of each support column. A crossbeam is fixedly connected between the tops of the two movable columns. Two suspension assemblies are mounted on the outer side of the crossbeam, and each suspension assembly includes an electric hoist that is rotatably connected to the crossbeam. By moving the two electric hoists to positions above both ends of the equipment, and then simultaneously hoisting the equipment from both ends using wire ropes one and two, the stability of the hoisting is improved. The two electric hoists can respectively wind up and pull the wire rope one on their respective winding wheels, thereby gradually tilting the equipment to a specified installation angle. Thus, the hoisting device can not only stabilize the hoisting of the equipment but also assist in adjusting the installation tilt angle of the equipment.

[0004] The aforementioned patent proposes that by moving two electric hoists to positions above the two ends of the equipment respectively, and then simultaneously hoisting the equipment from both ends using wire rope one and wire rope two, the stability of the equipment hoisting can be improved. However, in actual use, the load distribution of the equipment is uneven during the hoisting process, and the tension of the two wire ropes is different, which causes the hoisting to tilt, increases the risk of equipment damage, and may even cause the equipment to go out of control or a hoisting accident. Utility Model Content
