[0005] The solid tire is provided as two and connected through a rotating shaft, the support rod is fixedly arranged at the middle part of the rotating shaft, the fixed steel pipe is fixedly arranged at the top of the support rod, the movable steel pipe is inserted into the fixed steel pipe, the first fastening screw is threadedly connected at both ends of the fixed steel pipe to fasten the movable steel pipe, the hoisting sleeve is sleeved at one end of the movable steel pipe and fastened through the second fastening screw, and the lifting hook is arranged on the hoisting sleeve.

[0006] Optionally, a first reinforcing connecting rod is arranged between the rotating shaft and the support rod.

[0007] Optionally, a second reinforcing connecting rod is arranged between the fixed steel pipe and the support rod.

[0008] Optionally, a T-shaped groove is arranged at the top of the movable steel pipe, and one end of the second fastening screw is abutted in the T-shaped groove.

[0009] Optionally, the support rod is provided as two parts, i.e., a fixed part fixedly connected with the rotating shaft and a rotating part fixedly connected with the fixed steel pipe, the rotating part is inserted into the fixed part and rotatable on the fixed part.

[0010] Optionally, a tapered roller bearing is arranged between the rotating part and the fixed part.

[0011] The technical scheme provided by the present application can have the following beneficial effects:

[0012] The application sets the force applying arm of main force as a movable steel pipe and inserts it into a fixed steel pipe, which facilitates dismounting and mounting when entering the construction site, reduces the length and size of the equipment as a whole, and facilitates entering the construction site. Meanwhile, the main lifting hook for hoisting is also mounted in a detachable manner by using a hoisting sleeve, so that the hoisting hook can be replaced according to the needs, and only the equipment and the hoisting sleeve need to be connected. When the auxiliary components need to be hoisted by the hook or other auxiliary clamps, the hoisting sleeve is connected again, so that even if the auxiliary clamps are complex or large, they can also be conveniently dismounted and moved into the construction site.
