[0036] The working principle of the above embodiment is as follows:

[0037] Electric drive:

[0038] When the electric drive mode is selected, the drive motor 3 is started, and through the connection of the shaft coupling 4 with the positioning shaft 20, the winding shaft 2 is driven to rotate, the groove roller 19 on the winding shaft 2 rotates accordingly, and the steel cable 5 is wound or released on the groove roller 19, thereby driving the elevator cabin 6 to rise or fall. The other end of the steel cable 5 is connected to the counterweight plate 8 for balancing the weight of the elevator cabin 6, ensuring the stability of the lifting operation.

[0039] Manual operation:

[0040] When manual operation is needed, first, the shaft coupling 4 is separated from the positioning shaft 20 by pressing it, disconnecting the electric drive, then the operator shakes the manual emergency crank 12, through the transmission system of the traction rope 10 and the pulley 11, drives the sliding steel rod 9 to slide up and down on the back side of the counterweight plate 8, and the up and down movement of the sliding steel rod 9 drives the steel cable 5 to be pulled or released, realizing the lifting or lowering of the elevator cabin 6. The design of the limiting clamping groove 18 and the fixed clamping block 17 ensures the stability and safety of the sliding steel rod 9 during movement.

[0041] Among them, the safety and protection mechanism:

[0042] In the electric drive mode, if a power failure or emergency occurs, it can be quickly switched to manual operation mode by separating the shaft coupling 4, ensuring that the lifting operation can continue. The manual emergency crank 12 serves as a backup operation means, providing emergency lifting capacity when the electric drive fails. The design of the load shaft shell 7 and the pulley 11 enhances the durability and safety of the device, reducing the likelihood of failure.

[0043] The beneficial effects of the above embodiment are as follows:

[0044] By integrating the electric drive and manual operation modes, not only is the operation switching process simplified, but also the flexibility and emergency response capability of the lifting operation are significantly improved. With the winding shaft 2, groove roller 19, and load shaft shell 7, the stability and safety of the lifting process are ensured. In addition, with the manual emergency crank 12, it can quickly switch to manual operation in the event of a power failure, ensuring the continuity of the operation and the safety of personnel and equipment, improving the lifting efficiency and reducing the maintenance cost.
