[0020] Example

[0021] The present utility model provides a lithium - battery hand chain hoist, as Figure 1-2 shown, which includes a hook 1, a driver body 4 and a lifting chain 5. The hook 1 includes an upper hook 101 and a lower hook 102. The lower hook 102 is connected to one end of the lifting chain 5. The fixed end of the lifting chain 5 is wound around the driver body 4. The driver body 4 can control the rolling up or loosening of the lifting chain 5, thereby controlling the extending length of the lifting chain 5. The upper end of the driver body 4 is connected to the upper hook 101. A driving shaft 7 is horizontally arranged in the driver body 4. The fixed end of the lifting chain 5 is connected to the driving shaft 7. As the driving shaft 7 rotates, the lifting chain 5 is coiled around the driving shaft 7 or released. One end of the driving shaft 7 extends out of the side end face of the driver body 4 as a driving end 3. The driving end 3 includes a driving gear 303, a first gear 302 and a second gear 301. The second gear 301 is connected to a driving worm 2. The driving worm 2 is connected to a lithium - battery hand drill 6. The second gear 301 meshes with the first gear 302, and the first gear 302 meshes with the driving gear 303.

[0022] The handle of the lithium - battery hand drill 6 is an insulating handle 602, which is suitable for the operation requirements of overhead line construction. A power switch 601 is arranged on the insulating handle 602, and the power switch 601 is used to control the rotation of the driving worm 2. A chute 603 is arranged at the lower part of the lithium - battery hand drill 6, and the chute 603 is used to install a high - power battery 604. The second gear 301 and the first gear 302 have opposite helix directions, and the driving gear 303 and the second gear 301 have the same helix direction. The fixed end of the lifting chain 5 is welded to the driving shaft 7. The shell material of the driver body 4 is aluminum alloy, which changes the defect of the heavy weight of the alloy steel material of the traditional hand chain hoist.

[0023] During the actual operation process, when the power switch 601 of the lithium - battery hand drill 6 is pressed, the lithium - battery hand drill 6 drives the rotation of the driving worm 2. The driving worm 2 drives the rotation of the second gear 301. Subsequently, the second gear 301, the first gear 302 and the driving gear 303 mesh and rotate with each other, driving the driving shaft 7 to rotate, and then controlling the lifting chain 5 to be coiled around the driving shaft 7 or released. This device transmits force to the gear through a thread, and increases the speed ratio through the transmission of force, so that the object to be lifted can be easily lifted, thereby reducing the manual handling operation, saving labor, reducing the labor intensity of workers, and changing the driving direction of the hand chain by 90° through the worm - gear mechanism, which is beneficial for the operator to operate in the limited operation space at high altitude.

[0024] Therefore, the present utility model adopts a lithium - battery hand chain hoist with the above - mentioned structure to solve the problems existing in the prior art, such as time - consuming and laborious operation, low efficiency, high fatigue degree of operators and certain potential safety hazards. Moreover, the present utility model has a simple structure, a small volume, a light weight and is easy to operate.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions of the present utility model or make equivalent replacements, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
