[0002] Hoisting generally refers to the installation and positioning of equipment by a crane or a hoisting mechanism. Hoisting is a specific term for equipment positioning. Hoisting generally requires the cooperation of a lifting tool (or lifting rope). Traction generally means lifting an object and adjusting its height. When processing electromechanical equipment, especially large electromechanical equipment, it is usually necessary to use hoisting and traction equipment to hoist large parts and assemble the parts.

The hoisting component includes a U-shaped plate, a bidirectional threaded rod, a sliding block, a driving motor, a placement plate and a limiting rod. The bidirectional threaded rod is rotatably installed on the inner walls of the front and rear sides of the U-shaped plate. The sliding block is threadedly installed on the outer wall of the bidirectional threaded rod. By controlling the driving motor to start, the driving motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the sliding block to move relatively. The hoisting component can be used for hoisting electromechanical equipment. In this utility model, the triangle formed between the rope and the placement plate has a certain stability. The stable hoisting keeps the electromechanical equipment balanced during hoisting and can reduce accidental risks.

[0004] At present, there are still some deficiencies in a hoisting structure for electromechanical equipment processing. For example: Generally, large electromechanical equipment has a high cost. When the boom drives the electromechanical equipment to move, the electromechanical equipment sways, and there may be a situation where the electromechanical equipment falls, resulting in damage to the electromechanical equipment.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] By setting the air cushion, after the staff hangs the electromechanical equipment on the hook, the driving motor is started to drive the screw rod to rotate, lifting the electromechanical equipment. At the same time, when the screw rod rotates, the reciprocating screw rod is driven to rotate through the pulley and the belt. During the rotation of the reciprocating screw rod, the air pumping rod outside the reciprocating screw rod moves up and down reciprocally, driving the piston block to pump air into the air cushion through the air pump. Thus, when the electromechanical equipment is lifted, the air cushion is filled. When the electromechanical equipment drops during the movement, the air cushion at the bottom protects the lifted electromechanical equipment.

[0021] By setting the pressure valve, after the air pump continuously inflates the air cushion, when the air pressure in the air cushion reaches the maximum, through the pressure valve, the gas in the air cushion is released, reducing the pressure inside the air cushion and preventing the air cushion from being damaged due to excessive air pressure.
