A unloading rod 3 is fixedly arranged at the center position of the top end of the clamp assembly 2 to protect the galvanized round pipe from friction during the lifting process. A positioning cylinder 4 is fixedly arranged on the top end of the round pipe clamp 10. The movable bayonet 21 can be locked on the movable bayonet 21 to the positioning cylinder 4 after the galvanized round pipe is placed in place, so it is not easy to fall off, thereby ensuring safety.

[0027] Specifically, a limit rod 22 is rotatably provided on the outer side of the clamp assembly 2, and a pulley 23 is rotatably provided on the right side of the limit rod 22. The limit rod 22 can more easily pass through the positioning cylinder 4 structure through the pulley 23 to perform rapid limiting.

[0033] Working principle and process:

[0034] The lifting ring 1 is installed on the lifting tool, and the lifting ring 1 is moved to the outside of the galvanized copper pipe by the hydraulic lifting arm. The hydraulic lifting arm raises the lifting ring 1, and the lifting ring 1 can be controlled to lift the first rotating rod 5 and the second rotating rod 9. Through the action of gravity, the round pipe clamp 10 at the other end of the second rotating rod 9 is controlled to rotate and clamp on the outside of the galvanized round pipe for limiting. After clamping the galvanized round pipe, the movable bayonet 21 structure in the clamp assembly 2 on the outside of the first rotating rod 5 can be rotated to directly rotate and position the movable bayonet 21 to the outside of the positioning cylinder 4 at the top of the second rotating rod 9 to complete the positioning, limit the first rotating rod 5 and the second rotating rod 9 to stop rotating, and complete the clamping operation. After the hydraulic lifting arm is raised, the galvanized round pipe can be directly lifted by the second rotating rod 9. The clamping and positioning structure makes the lifting operation of the galvanized round pipe more convenient, and there is no need to use It is fixed with bolts, and after the pulley 23 at one end of the movable pin 21 passes through the positioning cylinder 4, the positioning frame 24 on the outside of the movable pin 21 is pushed to move and position to the outside of the limiting rod 22 to complete the limiting operation, thereby effectively maintaining the positioning of the limiting rod 22, enhancing the stability of the movable pin 21 positioned on the outside of the positioning cylinder 4, and avoiding the separation between the first rotating rod 5 and the second rotating rod 9 during the transportation of the lifting ring 1, which has better stability for clamping and lifting the galvanized round pipe. At the same time, after the movable pin 21 is rotated to the outside of the positioning cylinder 4, the second spring 7 can be used to push the pressure plate 6 to descend on the outside of the positioning cylinder 4, compressing the movable pin 21. After being transported to the lifting area, the positioning frame 24 is pushed to move and open, and the first spring 25 directly pushes the limiting rod 22 to rotate and open, completing the opening operation, and conveniently limiting the positioning cylinder 4.
