[0032] Further, such as Figure 3 、 4As shown, the fixed fixture 1 and the movable fixture 4 have the same structure, including a fixture base 5 mounted on a cylindrical guide rail 3 and an upper cover 9 hinged to the fixture base 5. The fixture base 5 has mounting holes 24 on both sides corresponding to the cylindrical guide rail 3. The fixture base 5 and the upper cover 9 are rotatably connected at one end by a rotating shaft 23, and are locked and fixed to each other at the other end by fixture fixing bolts 8. Insert rings 6 are installed in the inner holes of the fixed fixture 1 and the movable fixture 4, as shown in FIG. Figure 5 As shown, two annular protrusions 26 are provided on the outer wall of the insert ring 6. The annular protrusions 26 form a slot-type fit with the inner hole to achieve a detachable connection. Using insert rings 6 of different sizes can adapt to pipes of different sizes, increasing versatility. The insert ring 6 is suitable for pipes with diameters of 60mm-300mm.

[0033] Reference Attachment Figure 1 、 2 , 6, the base 10 is arranged below the clamping base 2. The lifting assembly 12 is arranged between the clamping base 2 and the base 10, and can drive the clamping base 2 to move up and down relative to the base 10. Two lifting link guide rails 11 are arranged in parallel on the base 10, and a guide rail slide 16 is provided on the lifting link guide rail 11. The two ends 21 of the transmission rod 15 pass through the corresponding guide rail slide 16, and one of the ends 21 is connected to the lifting link top block 18 for transmission.

[0035] The working process of this utility model:

[0036] When two water pipes are connected, one of the pipes is placed in the fixed fixture 1 and the other pipe is placed in the movable fixture 4. The corresponding size of the embedded ring 6 is used to adapt to the pipe size. The embedded ring 6 cooperates with the fixture through two annular protrusions 26 and is fixed as shown in FIG. Figure 3 、 4As shown, the upper cover 9 of the clamp seat 5 is then closed and the clamp fixing bolts 8 are tightened. Since the fixed clamp 1 and the movable clamp 4 are coaxially arranged, the pipe alignment is automatically completed. At this time, the clamping hydraulic cylinder 17 can be controlled to push the movable clamp 4 to complete the pipe docking.

[0037] When the installation height needs to be adjusted, the lifting assembly 12 is moved, and the lifting connecting rod top block 18 is pushed by controlling the lifting hydraulic cylinder 7, so that the lifting connecting rod top block 18 moves linearly along the top block slide groove 19 on the base 10, driving the transmission rod 15 to slide along the lifting connecting rod guide rail 11 (guide rail slide groove 16), adjusting the "X"-shaped structural angle between the first connecting rod 13 and the second connecting rod 14, to realize the jacking or lowering of the clamping base 2 (support plate 25), thereby easily adjusting the pipe docking height to achieve the purpose of improving work efficiency.

[0038] The present invention is not limited to the details of the above exemplary embodiments. If a pipe with a larger diameter and a heavier weight is encountered, it can be more easily implemented by selecting a larger mechanism size and strengthening the structure according to the design style of the present invention, which are all within the scope of the present invention.

[0039] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
