[0004] The device of this patent can smoothly lift the torsional damper assembly by setting the lifting piece on the torsional damper assembly and hanging the hook on the frame assembly, making it convenient for operators to disassemble and assemble the torsional damper; however, since the inner contour formed by the upper and lower arc plates of this patent is adapted to the outer contour of the torsional damper of fixed specifications, the upper and lower arc plates of this patent can only lift torsional dampers of fixed specifications. When the device needs to lift torsional dampers of other specifications, the entire device needs to be replaced, and its operation steps are relatively cumbersome, which is inconvenient for staff to use. Utility Model Content

[0008] The inner cavity of the lifting bracket is provided with a driving mechanism for making the upper arc-shaped lifting plate slide up and down.

[0009] The further technical improvement of the present utility model is that the driving mechanism includes two rotating rods symmetrically connected to the inner cavity of the lifting bracket, the outer wall of the rotating rod is engraved with an external thread, the threaded sleeve on the external thread of the rotating rod is provided with a screw sleeve fixedly connected to the upper arc-shaped lifting plate, the screw sleeve is slidably connected to the inner cavity of the lifting bracket, and the rotating rod is rotated to make the screw sleeve on the external thread of the rotating rod slide up and down.

[0010] A further technical improvement of the present invention is that a turbine is fixedly mounted on the bottom end of the outer wall of the rotating rod, and a worm engaged with the turbine is rotatably connected to the inner cavity of the lifting bracket, and the rotating worm causes the turbine to move synchronously.

By adjusting it, the long hook can always be hung on the frame assembly, thereby facilitating better lifting of the torsional shock absorber in the future; when adjusting, the sliding rod is pulled to cause the spring sleeved on the outer wall of the sliding rod to undergo elastic deformation, and the movement of the sliding rod drives the two transmission plates fixed to it to move synchronously, and the two transmission plates drive the limit block to disengage from the limit groove inside the plug block. At this time, the limit of the plug block can be released. After the limit of the plug block is released, the long hook is moved up or down to change its installation height. After the height is adjusted, the sliding rod is released again, and the limit block can automatically enter the limit groove corresponding to the plug block through the elastic force of the spring. After the installation height of the long hook is adjusted, it is convenient to meet the different usage needs of the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-6 As shown, this embodiment provides a technical solution, an auxiliary installation tool for a torsional shock absorber, including a lifting bracket 1, the bottom end of the inner wall of the lifting bracket 1 is fixedly connected to a lower arc-shaped lifting plate 3 for supporting the torsional shock absorber, the top end of the inner wall of the lifting bracket 1 is elastically and slidingly connected to an upper arc-shaped lifting plate 31 that cooperates with the lower arc-shaped lifting plate 3, and an anti-slip pad 32 is fixedly installed on the side where the upper arc-shaped lifting plate 31 and the lower arc-shaped lifting plate 3 are close to each other.

[0030] A fixing frame 2 is provided on the lifting bracket 1 , and the fixing frame 2 is symmetrically rotated and connected to two long hooks 21 on a side away from the lifting bracket 1 .

[0031] The inner cavity of the lifting bracket 1 is provided with a receiving groove 33, and a worm 36 is rotatably connected between the two inner side walls of the receiving groove 33 through a bearing. One end of the worm 36 passes through the receiving groove 33 and the lifting bracket 1 in sequence and extends to the outside of the lifting bracket 1. Two rotating rods 34 are symmetrically rotatably connected between the top and bottom ends of the inner wall of the receiving groove 33. A worm gear 35 engaged with the worm 36 is fixedly sleeved on the outer wall of the rotating rod 34. An external thread 37 is provided on the outer wall of the rotating rod 34 and on the side away from the worm gear 35. A threaded sleeve 38 slidingly connected to the receiving groove 33 is threaded on the outer wall of the external thread 37. The threaded sleeve 38 is fixedly connected to the upper arc-shaped lifting plate 31. Rotating the worm 36 causes the two worm gears 35 to rotate synchronously, and the rotation of the worm gear 35 drives the rotating rod 34 to move synchronously.

[0032] The fixing frame 2 is symmetrically fixedly connected to one side of the lifting bracket 1, and the inner cavity of the lifting bracket 1 is provided with a slot 23 that cooperates with the insert block 22. The inner cavity of the lifting bracket 1 is provided with an inner groove 24 below the slot 23. A sliding rod 25 is slidably connected to the outer wall of the lifting bracket 1. One end of the sliding rod 25 passes through the lifting bracket 1 and the inner groove 24 in turn and extends to the inner cavity of the inner groove 24. The sliding rod 25 extends to the inner cavity of the inner groove 24 and is symmetrically fixedly connected to two transmission plates 26. An outer sleeve 27 is fixedly connected to the outer wall of the transmission plate 26. The inner cavity of the outer sleeve 27 is elastically slidably connected with an inner sleeve 271. The inner sleeve 271 is fixedly connected to a limiting block 28 on the side away from the outer sleeve 27. The inner cavity of the insert block 22 is provided with a plurality of limiting grooves that cooperate with the limiting block 28.

[0033] When the present invention is in use, the installation height of the long hook 21 can be adjusted according to the frame structure of the actual adapted vehicle model. By adjusting it, the long hook 21 can always be hung on the frame assembly, thereby facilitating better lifting of the torsional shock absorber in the future. When adjusting, the sliding rod 25 is pulled to cause the spring sleeved on the outer wall of the sliding rod 25 to undergo elastic deformation. The movement of the sliding rod 25 drives the two transmission plates 26 fixed thereto to move synchronously, and the two transmission plates 26 drive the limit block 28 to disengage from the limit groove inside the insert block 22. At this time, the limit of the insert block 22 can be released. After the limit of the insert block 22 is released, the long hook 21 is moved up or down to change its installation height. After the height is adjusted, the sliding rod 25 is released again, and the elastic force of the spring causes the limit block 28 to automatically enter the limit groove corresponding to the insert block 22.

[0034] After the installation height of the long hook 21 is adjusted, the long hook 21 connected to the fixing frame 2 is used to conveniently hang the entire device on the frame assembly. After hanging, the torsion damper to be lifted is placed on the lower arc-shaped lifting plate 3 in the lifting bracket 1. The lower arc-shaped lifting plate 3 is used to facilitate its initial lifting, and then the height of the upper arc-shaped lifting plate 31 sliding down is controlled according to the size of the torsion damper. When adjusting, the worm 36 is rotated to make the two worm wheels 35 engaged therewith rotate synchronously. When the worm wheel 35 rotates, the two rotating rods 34 are driven to rotate synchronously, and the outer wall thereof is driven by the rotation of the two rotating rods 34. The external thread 37 on the upper part rotates synchronously. At this time, the screw sleeve 38 on the external thread 37 will drive the upper arc-shaped lifting plate 31 fixedly connected thereto to move toward the lower arc-shaped lifting plate 3. The movement of the upper arc-shaped lifting plate 31 facilitates the fixation of the torsional vibration damper, thereby facilitating further lifting thereof. Since the side close to the upper arc-shaped lifting plate 31 and the lower arc-shaped lifting plate 3 is fixedly installed with an anti-slip pad 32, the movement of the upper arc-shaped lifting plate 31 not only facilitates the lifting of torsional vibration dampers of different sizes, but also ensures that the lifting force is moderate, thereby facilitating subsequent use by the staff;

[0035] After the lifting work is completed, the worm 36 can be rotated in the opposite direction to move the upper arc-shaped lifting plate 31 upward, thereby facilitating the release of the limit of the torsional vibration damper and facilitating its removal.
