A vertical rod 8 is fixedly installed on the top of the blocking block 7, and the top of the vertical rod 8 passes through the liquid storage tank 5 and extends to the outside of the liquid storage tank 5 and is fixedly sleeved with a horizontal plate 9, and the bottom end of the horizontal plate 9 is movably connected to the top of the liquid storage tank 5, and a dual-axis motor 10 is fixedly installed on the top of the front end of the liquid storage tank 5, and the other end of the output shaft of the dual-axis motor 10 is fixedly sleeved with a rotating shaft 11, and a long rod 12 is fixedly sleeved on the outer surface of the rotating shaft 11, and a short rod 13 is movably sleeved at the rear end of the long rod 12, and the outer surface of the short rod 13 is fixedly connected to the outer surface of the horizontal plate 9.
[0028] When the dual-axis motor 10 is started, the rotating shaft 11 will drive the long rod 12 to rotate. Since the long rod 12 and the short rod 13 are movably connected, the inner surface of the long rod 12 will generate a thrust on the outer surface of the short rod 13, pushing the short rod 13 to move upward with the cross plate 9, the vertical rod 8 and the block 7, thereby separating the block 7 and the conduit 6. At this time, the lubricating fluid inside the liquid storage tank 5 will flow through the conduit 6 to the outer surface of the circular shaft 3, thereby lubricating and maintaining the circular shaft 3 to prevent rust and jamming between the circular shaft 3 and the bracket 2, which will affect the rotation of the guide wheel 4.

A tightener 21 is movably installed at the bottom inside the lifting ring 20, and the inner surface of the tightener 21 is movably sleeved on the outer surface of the cable 18.
[0034] As a technical optimization solution of the utility model, the inner surface of the fixed shaft 19 and the outer surface of the hanging ring 20 are both smooth, ensuring that the hanging ring 20 will not get stuck when rotating along the inside of the fixed shaft 19.
[0035] refer to Figure 4 , Figure 5 , Fig. 9 and Fig.10 A fixed block 22 is fixedly installed on the right side of the bottom end of the beam 1, and a movable block 23 is movably sleeved inside the fixed block 22. The bottom end of the movable block 23 is fixedly connected to the right side of the top end of the lifting ring 20.
[0036] As a technical optimization solution of the utility model, when the lifting ring 20 is pushed, the lifting ring 20 will rotate along the inner surface of the fixed block 22 with the movable block 23 and the fixed shaft 19 as the axis.
[0037] refer to Figure 4 , Figure 5 , Fig. 9 and Fig.10The left end of the fixed block 22 is movably sleeved with a round rod 24, the right end of the round rod 24 passes through the movable block 23 and the fixed block 22 and extends to the outside of the fixed block 22, the right end of the inside of the round rod 24 is movably sleeved with a limit block 25, and the outer surface of the limit block 25 is fixedly sleeved with the inner surface of the right end of the fixed block 22.

[0040] As a technical optimization solution of the present invention, due to the restoring effect of the spring 27, the handle 26 will drive the round rod 24 to move and then return to its original position.
[0041] The working principle and use process of this utility model:
[0042] During the use of the lifting mechanism, if the operator finds that the rotation of the guide wheel 4 is obviously stuck, he starts the dual-axis motor 10, so that the rotating shaft 11 drives the long rod 12 to rotate, so that the inner wall of the long rod 12 generates a thrust on the outer surface of the short rod 13, pushing the short rod 13 to move upward along the outer surface of the liquid inlet pipe 14 with the cross plate 9 until the cross plate 9 contacts the baffle 15. At this time, the vertical rod 8 fixedly connected to the cross plate 9 will move with the block 7, so that the block 7 and the conduit 6 are separated, and then the lubricating fluid inside the liquid storage tank 5 flows through the conduit 6 to the outer surface of the round shaft 3, thereby lubricating and maintaining the round shaft 3 to prevent rust and jamming between the round shaft 3 and the bracket 2 from affecting the rotation of the guide wheel 4.
[0043] When the operator uses the lifting mechanism to lift objects, the tensioner 21, the locker 17 and related components can be used to realize the free extension and retraction of the cable 18, and the load-bearing capacity of the cable 18 can be increased when the locker 17 is working. When the tensioner 21 is inspected and maintained, the operator pulls the handle 26 to move the round rod 24 along the inner surface of the fixed block 22 and the movable block 23 and stretch the spring 27 until the round rod 24 and the movable block 23 are separated. Then the operator pushes the lifting ring 20 to make the lifting device 18 move freely. The ring 20 rotates with the movable block 23 around the fixed shaft 19, thereby opening the lifting ring 20, and then the operator can remove the tensioner 21. After the tensioner 21 is overhauled and reset, the operator releases the handle 26. At this time, under the restoring action of the spring 27, the round rod 24 will re-engage with the movable block 23, thereby locking the position of the movable block 23 and the lifting ring 20, so that the tensioner 21 can be quickly disassembled and installed, thereby improving the convenience of using the lifting mechanism.
