[0002] Electromechanical maintenance refers to the repair of failed parts of electromechanical equipment and the inspection of electromechanical equipment, etc., also known as electromechanical equipment repair. The basic contents of electromechanical maintenance include: equipment maintenance, equipment inspection and equipment repair. When repairing electromechanical equipment, many electromechanical equipment need to be lifted to an appropriate height so that maintenance personnel can use tools for inspection and repair.

[0003] In the prior art, the patent number CN220131794U discloses a lifting device applied to the maintenance of electromechanical equipment, including a bottom plate and a top plate. The top plate is arranged at the upper end of the bottom plate. Four corners of the lower side of the bottom plate are fixedly connected with universal wheels.

The lifting mechanism includes a clamping unit and a lifting unit. The clamping unit is arranged at the upper end of the top plate, and the lifting unit is arranged at the upper end of the bottom plate. When using this lifting device applied to the maintenance of electromechanical equipment, first place the electromechanical equipment to be repaired on the upper end of the top plate, and then rotate the handle to drive the threaded rod to rotate, drive the threaded rod to move relative to the fixed plate, and thus drive the moving plate to move together until the moving plate moves to both ends of the electromechanical equipment, and then stably fix the electromechanical equipment on the upper end of the top plate.
