[0022] The extrusion positioning device 4 includes a U-shaped frame 401 fixedly installed on the outer side of the lifting plate 3. The U-shaped frame 401 has a sliding positioning plate 402 inside. A movable crossbeam 403 is fixedly installed on the upper surface of the positioning plate 402. An extrusion spring column 404 is fixedly installed on the upper surface of the movable crossbeam 403. An extrusion plate 405 is fixedly installed on the upper surface of the extrusion spring column 404. An arc-shaped positioning plate 406 is fixedly installed on the upper surface of the extrusion plate 405. A rotatable linkage rod 407 is provided on the outer side of the movable crossbeam 403. A sliding bracket 408 that slides against the bottom of the U-shaped frame 401 is rotatably provided at the bottom of the linkage rod 407. A positioning bracket 409 is fixedly installed on the lower surface of the U-shaped frame 401. A positioning rod 410 inserted into the positioning plate 402 passes through the interior of the positioning bracket 409.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, a circular through hole is provided on the front side of the upper surface of the lifting plate 3, and the steel wire rope 14 passes through the inside of the circular through hole. The circular through hole on the front side of the upper surface of the lifting plate 3 facilitates the better lifting of the steel wire rope 14.

[0024] Specifically, such as Figure 3 As shown, the upper surface of the arc-shaped positioning plate 406 is provided with a positioning transverse groove, and the outer surface of the positioning cylinder 11 is fixedly installed with a positioning transverse bar. The positioning transverse groove and the positioning transverse bar are adapted to each other.

[0025] The working principle of this utility model is as follows:

[0026] S1. When lifting construction materials, start the drive motor 6. The output end of the drive motor 6 drives the drive gear 7 to rotate. The drive gear 7 meshes with the rotating gear 10 to drive the rotating column 9 to rotate. The rotating column 9 drives the winding wheel 12 to rotate. The winding wheel 12, together with the guide wheel 13, drives the wire rope 14 and the hook 15 to move upward to lift the construction materials.

[0027] S2. After raising to a suitable height, stop and control the positioning plate 402 and the moving crossbar 403 to drive the compression spring column 404 to move upward. Under the action of its own elasticity, the compression spring column 404 drives the compression plate 405 and the arc positioning plate 406 to lock the positioning cylinder 11 to position the winding wheel 12.

[0028] S3. Simultaneously, the positioning rod 410 is inserted through the positioning bracket 409 into the interior of the positioning plate 402 to position the arc-shaped positioning plate 406.

[0029] In summary, the portable lifting device for erecting the power tower, by setting up a positioning plate 402 and a movable crossbeam 403, under the action of the elastic force of the compression spring column 404, drives the compression plate 405 and the arc-shaped positioning plate 406 to lock the positioning cylinder 11 and perform positioning operation on the winding wheel 12. This results in a better positioning effect on the winding wheel 12, and can ensure the locking effect of the rope in special situations, which helps to make the use safer and avoid the occurrence of safety accidents.

[0030] The portable lifting device used for erecting the power tower uses a positioning rod 410 that passes through the positioning bracket 409 and is inserted into the positioning plate 402 to position the arc-shaped positioning plate 406. This results in a better locking effect between the arc-shaped positioning plate 406 and the positioning cylinder 11, ensuring better safety during use and contributing to safer and more stable operation.

[0031] The portable lifting device used for erecting the power tower uses a drive motor 6 to drive a drive gear 7 to mesh with a rotating gear 10, which in turn drives a rotating column 9 and a winding wheel 12 to work with a guide wheel 13 to tighten the steel wire rope 14. This helps to better lift construction materials and facilitates the erection of the power tower.
