[0039] The working principle and usage process of the present invention: During the use of a safety type electric hoist that is convenient for cooling, first, the outside air enters the rotating motor 3 through the air inlet channel 401 and is blown out from the air outlet 402, thereby taking away the temperature inside the rotating motor 3, achieving the cooling effect, preventing the temperature of the rotating motor 3 from rising and affecting the use, and ensuring the operation of the electric nursing hoist. In addition, the heat generated by the rotating motor 3 is conducted through the heat dissipation plate 404. At the same time, the coolant inside the liquid tank 408 is led out through the cooling pipe 406 to exchange heat with the heat dissipation plate 404, thereby improving the heat dissipation efficiency. In addition, the coolant inside the liquid tank 408 is blown and cooled by the blowing motor 409, so that the temperature of the coolant can be quickly cooled down to ensure the heat exchange efficiency;

[0040] Next, by rotating the nut 707, the nut 707 drives the screw rod 708 to rotate, so that the screw rod 708 drives the two connecting plates 704 to move, the connecting plates 704 drive the load-bearing rollers 705 to move, reducing the distance between the two load-bearing rollers 705 on both sides, and then clamping on the I-shaped guide rail, improving the installation efficiency of the electric hoist. The drive motor 706 drives the load-bearing rollers 705 to rotate, and at the same time through belt drive, the load-bearing rollers 705 can rotate together to ensure that the electric hoist does not deviate during movement. In addition, by rotating the nut 707 in the reverse direction, the screw rod 708 drives the movable plate 703, thereby increasing the distance between the two load-bearing rollers 705 on both sides and releasing the clamping of the load-bearing rollers 705, facilitating the removal of the electric hoist from the I-shaped guide rail;

[0041] Finally, when the rotating motor rotates, the rope 8 is wound and unwound, and at the same time, the wire guide plate 12 limits and guides the rope 8, thus preventing the rope 8 from being entangled and ensuring the winding effect of the rope 8. At the same time, the roller 13 drives the wire guide plate 12 to slide along the rectangular groove 11, enabling the wire guide plate 12 to adjust the limiting position along with the winding and unwinding of the rope 8, thereby ensuring the limiting effect of the wire guide plate 12.

[0042] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
