[0026] The clamping assembly comprises a pushing block 7 , the inner wall of the bearing plate 6 is slidably connected with the pushing block 7 , and one end of the pushing block 7 is fixedly connected with a clamping ring 8 .

[0027] Among them, Figure 3 As shown, the push block 7 is provided with a thread groove that matches the first threaded shaft 3. The first threaded shaft 3 forms a spiral structure with the push block 7 through the turntable 2, which is conducive to the rotation of the first threaded shaft 3, so that the push block 7 can move spirally on the outer wall of the first threaded shaft 3 to provide clamping power.

[0028] Among them, Figure 3 As shown, the bearing plate 6 is provided with a sliding groove that matches the push block 7. The push block 7 forms a sliding structure with the bearing plate 6 through the first threaded shaft 3, which is beneficial to ensure the stability of the push block 7 when moving and clamping and prevent deviation.

[0029] Among them, Figure 2 As shown, the bearing plate 6 is provided with a sliding groove that matches the clamping ring 8. The clamping ring 8 forms a sliding structure with the bearing plate 6 through the pushing block 7, which is beneficial to ensure the synchronous stability when the clamping ring 8 clamps the pipeline and prevent uneven force on one side.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, a motor 9 is provided on the top of the wheel 1, one end of the motor 9 is fixedly connected to a bottom plate 10, one end of the motor 9 is fixedly connected to a second threaded shaft 11, an outer wall of the second threaded shaft 11 is spirally connected to a sliding block 12, an outer wall of the sliding block 12 is rotatably connected to a connecting rod 13, one end of the connecting rod 13 is rotatably connected to a connecting block 14, the top of the connecting block 14 is fixedly connected to a top plate 15, and the bottom of the top plate 15 is fixedly connected to a telescopic column 16.

The second threaded shaft 11 forms a spiral structure with the sliding block 12 through the motor 9, which is conducive to the sliding block 12 moving on the outer wall of the second threaded shaft 11 to adjust the position of the connecting rod 13 to achieve the purpose of lifting.

[0033] Among them, Figure 1 As shown, two groups of connecting rods 13 are provided, and the position relationship of the two groups of connecting rods 13 is symmetrically distributed about the midpoint of the bottom plate 10, which is beneficial to ensure the stability of the lifting and lowering of the top plate 15 and prevent one side from tilting.

[0034] When in use: first, put the pipe into the clamping ring 8, manually rotate the turntable 2, so that the turntable 2 drives the first threaded shaft 3 to rotate, and the rotation of the first threaded shaft 3 causes the spirally connected push block 7 to move, so that the push block 7 slides in the sliding groove provided in the bearing plate 6, driving the clamping ring 8 to clamp the pipe, so that the pipe is stabilized in a position, which is convenient for welding;

[0035] Finally, by operating the motor 9 fixed on the outer wall of the bottom plate 10, the motor 9 drives the second threaded shaft 11 to rotate, causing the spirally connected sliding block 12 to move on its outer wall, and at the same time causing the position of the connecting rod 13 to change, thereby adjusting the height of the top plate 15 and contracting the telescopic column 16, thereby raising the position of the pipeline and facilitating the docking between the pipelines.
