However, it is inconvenient to lift the pipe segments with curved surfaces, so a special hanger for socket-type pipe segments is provided. Utility Model Content

[0004] The utility model aims to provide a special hanger for a socket-and-spigot type pipe segment, which solves the problem.

[0006] By adopting the above technical scheme, the L-shaped block can be rotated on the three-shaped block, and the pins are inserted into the grouting holes on the pipe segment, and then the hoisting machine is connected to the lifting hole. Therefore, when the three-shaped block is lifted, since the three-shaped block and the L-shaped block are rotatably installed, the three-shaped block and the L-shaped block exert force in opposite directions, and the protrusion in the middle of the three-shaped block can abut the upper end of the pipe segment, thereby tightening the pipe segment with the cooperation of the protection mechanism, and further stabilizing the pipe segment with the cooperation of the auxiliary locking mechanism. The hoist is convenient for installation on the pipe segment and speeds up the work hoisting efficiency.

[0007] Optionally, the protection mechanism includes a first mounting plate, the first mounting plate is fixedly connected to the inner side below the three-type block, and a first stop block is fixedly installed on the inner side of the first mounting plate.

[0008] By adopting the above technical solution, the three-type block can fix the first mounting plate, and the first mounting plate can fix the first abutment block, thereby abutting the pipe segment.

[0009] Optionally, a second mounting plate is fixedly connected to the inner side of the middle portion of the L-shaped block, and a second stop block is fixedly mounted on the inner side of the second mounting plate.

[0010] By adopting the above technical solution, the L-shaped block can fix the second mounting plate, and the second mounting plate can fix the second abutment block, thereby abutting the pipe segment.

[0011] Optionally, a third mounting plate is fixedly connected to the lower end of the protrusion in the middle of the three-type block, and a third stop block is fixedly mounted on the lower end of the third mounting plate.

[0013] Optionally, the auxiliary locking mechanism includes a connecting block, which is fixedly connected to the outer wall raised in the middle of the three-type block, and a clamping block is rotatably installed on the outer wall of the connecting block away from the three-type block, and the bottom of the clamping block is set in an inverted L shape.

[0014] By adopting the above technical solution, the three-type block can fix the connecting block, and the connecting block can provide rotational support for the clamping block. The clamping block can be placed on the upper end of the pipe segment, and the L-shaped setting below the clamping block can clamp the groove of the pipe segment.

[0015] Optionally, a handle is fixedly connected to the outer wall below the L-shaped block.

[0016] By adopting the above technical solution, the L-shaped block can fix the handle, and the handle can facilitate the staff to pull the L-shaped block.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] The technical solution of the present application allows the L-shaped block to rotate on the three-shaped block, and the pins are inserted into the grouting holes on the pipe segments, and then the hoisting machine is connected to the lifting holes. Therefore, when the three-shaped block is lifted, since the three-shaped block and the L-shaped block are rotatably installed, the three-shaped block and the L-shaped block exert force in opposite directions, and the protrusion in the middle of the three-shaped block can abut against the upper end of the pipe segment, thereby tightening the pipe segment with the cooperation of the protection mechanism, and further stabilizing the pipe segment with the cooperation of the auxiliary locking mechanism. The hoist is convenient for installation on the pipe segment and speeds up the work hoisting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
