The end of the top of the base 10 is welded and fixed with a connecting block 13, and the lower end surface of the connecting block 13 is provided with a pulley 14. The outer wall of the L-shaped support rod 12 is fixedly sleeved with a horizontal plate 15, and the upper end surface of the horizontal plate 15 is fixedly installed with a driving motor 16. The driving motor 16 is the driving force of the winding roller 17, which is used to drive the winding roller 17 to rotate. The output end of the driving motor 16 is provided with a winding roller 17, and a lifting rope 18 is wound around the winding roller 17. The end of the lifting rope 18 passes through the pulley 14 and the end is connected to the sling assembly;

[0030] The side wall of the connecting block 13 is provided with a stabilizing component for assisting the up and down movement of the lifting rope 18;

[0032] In addition, the stabilizing component includes a guide plate 20, a guide rail 21, a groove 22, a ball bearing 23, an auxiliary guide block 24 and a slider 25. The guide plate 20 is fixedly connected to the outer wall of the connecting block 13, and a group of guide rails 21 are provided on the inner wall of the guide plate 20. The guide rails 21 are provided with an adaptive slider 25. An auxiliary guide block 24 is fixedly sleeved on the outer wall of the lifting rope 18. The auxiliary guide block 24 is fixedly connected to the outer wall of the slider 25. A plurality of grooves 22 are provided between the two guide rails 21, and adaptive balls 23 are provided inside the plurality of grooves 22.

[0033] During the specific implementation of this solution, the auxiliary guide block 24 is driven to move up and down during the extension and retraction of the lifting rope 18. The auxiliary guide block 24 slides up and down on the side wall of the guide plate 20 through the cooperation of the slider 25 and the guide rail 21, so as to avoid large shaking of the lifting equipment assembly during the lifting process and improve the stability of the lifting. The slider 25 is used in conjunction with the ball 23, so that the friction force on the slider 25 is reduced, further improving the smoothness of the contraction of the lifting rope 18.

[0034] The groove 22 is a hemispherical structure, and the ball 23 rolls freely in the groove 22 . The sliding surface of the slider 25 contacts the rolling surface of the ball 23 .

[0035] The two guide rails 21 are laterally symmetrically arranged on the guide plate 20 , and the two guide rails 21 are vertically arranged on the guide plate 20 .

[0036] In addition, the sling assembly includes a hanging plate 30, a mounting groove 31 and a hook 32. The top of the hanging plate 30 is connected to the bottom end of the hanging rope 18. A mounting groove 31 is provided on the hanging plate 30. The hook 32 is slidably connected in the mounting groove 31. Through holes 33 are provided on both sides of the top of the hook 32. The lower end surface of the hanging plate 30 is provided with an array of threaded holes 34, and a positioning pin 35 is vertically inserted into the threaded hole 34.

[0037] During the specific implementation of this solution, when hoisting the shock absorber, the spacing between the hooks 32 is adjusted by manually moving the hooks 32. After the position of each hook 32 is debugged, the positioning pin 35 is passed through the threaded hole 34 and the through hole 33 from bottom to top, and the top of the positioning pin 35 passes through the through hole 33 to limit and fix the hook 32, so as to prevent the positioning pin 35 from shifting during the hoisting process, and can prevent the hook 32 from shifting to a certain extent.

[0038] The top end of the positioning pin 35 passes through the through hole 33 to limit and fix the hook 32.

[0039] The cross section of the installation slot 31 is a T-shaped structure, the top of the hook 32 is a T-shaped structure, and the hook 32 slides vertically in the installation slot 31 .

[0040] In addition, the adjustment component includes a servo motor 40, a rotating shaft 41, a driving gear 42 and a driven gear 43. The driven gear 43 is fixedly sleeved on the bottom outer wall of the L-shaped support rod 12, and the servo motor 40 is fixedly installed on the upper end surface of the base 10. The output end of the servo motor 40 is provided with a rotating shaft 41, and the driving gear 42 is fixedly sleeved on the top outer wall of the rotating shaft 41. The driving gear 42 is meshed and connected with the driven gear 43.

[0041] During the specific implementation of this solution, by starting the servo motor 40, the servo motor 40 drives the driving gear 42 on the rotating shaft 41 to rotate, and the driving gear 42 is meshed and connected with the driven gear 43, so that the L-shaped support rod 12 moves synchronously with the rotating shaft 41, which can drive the sling assembly to adjust the direction, so that the shock absorber and the port of the main body can be quickly docked.

[0042] The bottom end of the L-shaped support rod 12 is rotatably connected to the base 10 via a bearing.

[0043] A push rod is provided on one side of the upper end surface of the base 10 .

[0044] Working principle: When in use, the device as a whole is moved by the universal wheel 11, and the driving motor 16 is used to drive the winding roller 17 to retract and release the lifting rope 18, so that the lifting rope 18 drives the lifting device assembly to move up and down, so that the shock absorber and the main machine are in the same horizontal state, which is convenient for the staff to install and handle it. In the process of extending and retracting the lifting rope 18, the auxiliary guide block 24 is driven to move up and down. The auxiliary guide block 24 slides up and down on the side wall of the guide plate 20 through the cooperation of the slider 25 and the guide rail 21, so as to avoid large shaking of the lifting device assembly during the lifting process and improve the stability of the lifting. The slider 25 is used in conjunction with the ball 23, so that the friction force on the slider 25 is reduced, further improving the lifting rope 1 8. Smoothness during contraction. By starting the servo motor 40, the servo motor 40 drives the driving gear 42 on the rotating shaft 41 to rotate, and the driving gear 42 is meshed with the driven gear 43. Therefore, the L-shaped support rod 12 moves synchronously with the rotating shaft 41, which can drive the sling assembly to adjust the direction, so that the shock absorber and the port of the main body can be quickly docked. When hoisting the shock absorber, the spacing between them is adjusted by manually moving the hook 32. After the position of each hook 32 is debugged, the locating pin 35 is passed through the threaded hole 34 and the through hole 33 from bottom to top. The top of the locating pin 35 passes through the through hole 33 to limit and fix the hook 32, so as to avoid the locating pin 35 from shifting during the hoisting process, which can avoid the hook 32 from shifting to a certain extent.
