[0027] Furthermore, such as Figure 2 As shown, the end of the support plate 31 away from the pipeline is welded to the rotating shaft, and the end of the rotating shaft away from the support plate 31 is welded to the lifting rod 32. The end of the lifting rod 32 away from the rotating shaft is inserted into the sleeve 33. A rotating handwheel 34 is connected to the outer wall of the end of the lifting rod 32 extending out of the sleeve 33. Rotating the rotating handwheel 34 allows the lifting rod 32 to slide up and down inside the sleeve 33. The sleeve 33 is vertically welded to the lower base plate 37. An upper base plate 36 is welded to the outer wall of the end of the sleeve 33 away from the lower base plate 37. Multiple fixed brackets 35 are connected between the upper base plate 36 and the lower base plate 37.
[0028] In this embodiment, preferably, the support plate 31 is V-shaped so that the 4-inch to 8-inch pipeline can be stably abutted against the support plate 31.

[0030] Furthermore, such as Figure 1 As shown, one end of each of the multiple fixed brackets 35 is welded to the side of the lower base plate 37 away from the sleeve 33, and the other end of each of the multiple fixed brackets 35 away from the lower base plate 37 is welded to the upper base plate 36. The multiple fixed brackets 35 are welded at intervals between the upper base plate 36 and the lower base plate 37. The lower base plate 37 is welded with multiple sliding feet 38 at the end away from the sleeve 33. The multiple sliding feet 38 are slidably arranged on the sliding rails 4. Two sliding rails 7 are laid at intervals on the base 1. The two sliding rails 4 are arranged in parallel and are on the same straight line as the clamp 2.
[0031] In this embodiment, preferably, both the upper base plate 36 and the lower base plate 37 are rectangular. Fixed brackets 35 are welded to the four corners of the lower base plate 37, and the ends of the fixed brackets 35 away from the lower base plate 37 are welded to the four corners of the upper base plate 36. The base 1 is provided with two sliding rails 4, and the lower base plate 37 is provided with two sets of sliding feet 38. The two sets of sliding feet 38 slide on the two sliding rails 4 respectively to change the contact position of the support plate 31.

[0034] The working principle of the underwater pipeline assembly device in this utility model is as follows:
[0035] Two clamps 2 are spaced apart on the base 1, and are located on the same straight line. A sliding rail 4 is provided between the two clamps 2.

A baffle 5 is provided at the end of the sliding rail 4 to prevent the lifting support assembly 3 from disengaging from the rail.
[0036] Use clamp 2 to fix one end of the pipeline. Place the end of the pipeline away from clamp 2 on the support plate 31 of the lifting support assembly 3. The distance between the two lifting support assemblies 3 can be adjusted according to the length of the pipeline. Then, rotate the rotating handwheel 34 of the lifting support assembly 3 to adjust the position of the pipeline so as to carry out the pipeline assembly and welding work.
[0037] Based on an underwater pipeline assembly device, this invention uses a clamp 2 to hold one end of the pipeline, with the end of the pipeline away from the clamp 2 abutting against a support plate 31. A lifting rod 32, slidably mounted within a sleeve 33, adjusts the vertical position of the support plate 31, thereby adjusting the pipeline's position.

The pipeline is stably positioned between the clamp 2 and support plate 31, enabling pipeline assembly and welding. This invention allows for adjusting the support position of the support plate 31 according to the pipeline length and adjusting the horizontal position of the pipeline via the lifting rod 32, facilitating pipeline assembly and welding. It is safe and reliable during construction, easy to manufacture, reduces pipeline assembly and welding time, and lowers labor costs.
