[0033] The specific implementation process is as follows:

[0034] When the shaft forging needs to be lifted, the main hook 4 is first connected to the steel rope on the lifting equipment such as the gantry crane, and the connecting ring 24 is connected to the other two sets of steel ropes. Then, the steel rope is connected to the auxiliary hook 28 to lift the two ends of the shaft forging, and the middle of the shaft forging needs to be placed on the top of the bracket 61;

[0035] Then, the two ends of the shaft forging need to be leveled, and the user starts the driving motor 29 to start working. The driving motor 29 drives the reducer 210 to rotate the winding wheel 211 and drives the lifting rope 213 to lift. During the lifting, the lifting rope 213 acts on the lifting ring 261 inside the pressing mechanism 26, and the lifting ring 261 can pull the pulling arm 262. Then the pulling arm 262 acts on the connecting arm 263 and the linkage arm 264 at the lower end, so that the side plate 265 and the pressing plate 266 press and lift the auxiliary steel rope 25. During the lifting process, the side plate and the pressing plate 266 contact the stabilizing member 271 inside the top limiting assembly 27 to limit the position, so as to achieve stable lifting;

[0036] After leveling, the rotating rod 612 is rotated. The rotating rod 612 can rotate the active bevel gear 613 during the rotation process. When the active bevel gear 613 rotates, it also rotates the driven bevel gear 614. The rotating sleeve 615 in the middle of the driven bevel gear 614 rotates. The extending rods 616 at both ends of the inner side of the rotating sleeve 615 can extend to act on the limit blocks 63 at both ends. The limit blocks 63 are stably extended to both ends under the guidance of the guide rod 617 to be pressed and fixed in the position between the circular groove or the protrusion of the shaft forging.

[0037] Finally, the lifting and assembly work can be carried out through an external gantry crane or lifting equipment.

[0038] The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
