[0002] The lifting mechanism is the core component of the crane, also known as the "lifting mechanism". It is an essential component of the crane for lifting and lowering objects. The lifting mechanism is driven by a lifting motor through a coupling and a hollow shaft of a reducer to rotate the drum, so that the wire rope / cable wrapped around the drum drives the hook device to rise or fall. The power of the lifting mechanism is mainly provided by the lifting motor, and the lifting motor, like a conventional motor, is mainly composed of a motor housing, a rotor, a stator and a motor shaft. The existing motor shaft is cut from bar stock and then turned. The turned part includes the end face and the outer diameter.

A vertical rotary cylinder 462 is fixedly connected to the support plate 461. The top of the piston rod of the rotary cylinder 462 is fixedly connected with a connecting block 4621. A horizontal pressure rod 463 is fixedly connected to the connecting block 4621. The pressure rod 463 is located above the lead screw 45.

[0025] On the front side of the bottom plate 41, a support beam frame 1 extends out and is fixedly connected with a mounting plate 5. A longitudinal conveying motor 6 is fixedly connected to the mounting plate 5. A gear is fixedly connected to the rotating shaft of the conveying motor 6.

[0026] The upper side of the side of the adjusting base 42 close to the center of the bottom plate 41 is higher than the upper side of the side of the adjusting base 42 far from the center of the bottom plate 41.

[0034] A pallet 43 is provided on the conveying slide 4, and a motor shaft can be loaded in the V-shaped notch of the pallet 43. In order to prevent the motor shaft from moving upward and disengaging from the V-shaped notch of the pallet 43, when loading the motor shaft, its rotary cylinder 462 moves the pressing rod 463 to one side of the pallet 43, away from above the V-shaped notch, so as not to affect the placement of the motor shaft. During the moving and conveying process, the rotary cylinder 462 drives the pressing rod 463 to move to the upper side of the motor shaft to restrict the motor shaft from disengaging from the V-shaped notch of the pallet 43.
