A plurality of pipe support assemblies 5 are provided, and each pipe support assembly 5 is movably arranged on the support plate 4 to adjust the support points according to the length of the pipe and the welding position to ensure the stability of the pipe.
[0028] As Figure 2 and Figure 3As shown in the figure, the pipe support assembly 5 includes a bottom plate 51, a Y-shaped side plate 52, and a roller assembly 53. There are two Y-shaped side plates 52, which are arranged at intervals on the bottom plate 51. The upper part of the Y-shaped side plate 52 has two inclined plates 521 arranged obliquely downward, and the roller assembly 53 is located between the two inclined plates 521 arranged at intervals. Between the two groups of roller assemblies 53 is used to support and guide the pipe to be welded, so that the pipe remains stable during the welding process and at the same time facilitates the adjustment of the position of the pipe.
[0029] The roller assembly 53 includes a roller 531 and a mounting plate 532. There are two mounting plates 532 arranged at intervals, and there are two rollers 531. The two rollers 531 are rotatably arranged between the two mounting plates 532, so that the pipe can roll on the rollers 531, facilitating the adjustment of the position. The two mounting plates 532 are fixed between the two inclined plates 521 to ensure the stability of the roller assembly 53.
[0030] As Figure 4 shown, there are two groups of guide rails 41 arranged at intervals along the length direction on the support plate 4, and sliders 42 are arranged on the guide rails 41. There are multiple sliders 42, and each bottom plate 51 is connected to the corresponding slider 42, so that the pipe support assembly 5 can move on the support plate 4 to adjust the pipe support position according to actual needs.
[0031] As Figure 5 shown, the side plate of the slider 42 protrudes from the guide rail 41, and the side plate of the slider 42 extends downward to have a positioning plate 43. A threaded hole is arranged on the positioning plate 43, and a positioning bolt 44 is threadedly connected in the threaded hole. The positioning bolt 44 is used to abut against the side wall of the guide rail 41 to position the slider 42, ensuring that the pipe support assembly 5 does not move during the welding process.
[0032] As Figure 4 shown, the lifting assembly 3 includes a base 31, a first hinge plate 32, a second hinge plate 33, a third hinge plate 34, a fourth hinge plate 35, and a top seat 36. The lower end of the first hinge plate 32 is hinged to one end of the base 31, and the other end is hinged to the lower end of the third hinge plate 34. The lower end of the second hinge plate 33 is slidably arranged in the base 31, and the upper end is hinged to the lower end of the fourth hinge plate 35. The middle positions of the first hinge plate 32 and the second hinge plate 33 are hinged, and the middle positions of the third hinge plate 34 and the fourth hinge plate 35 are also hinged.

An adjusting shaft 39 is threadedly connected to the first adjusting plate 37 and the second adjusting plate 38. The rotation of the adjusting shaft 39 is used to drive the third hinge plate 34 and the fourth hinge plate 35 to approach and move away from each other, so as to drive the top seat 36 to lift and lower. The support plate 4 is connected to the top seat 36, thereby realizing the lifting and lowering of the support plate 4.
[0034] A hand wheel 391 is provided at the end of the adjusting shaft 39, which is convenient for the operator to rotate the adjusting shaft 39, thereby adjusting the height of the support plate 4.
[0035] Usage method:
[0036] When in use, first place the two pipes of the T-shaped pipe on the first pipe support and positioning mechanism 1 and the second pipe support and positioning mechanism 2. Then, according to the length and welding position of the pipes, adjust the positions of the respective pipe support assemblies 5 on the support plate 4 and fix them with positioning bolts 44. Next, by rotating the hand wheel 391, adjust the height of the support plate 4 so that the two pipes are in a suitable welding position. During the adjustment process, the design of the roller assembly 53 enables the pipes to roll on it easily, facilitating precise alignment.
[0037] When the two pipes are aligned, the operator can start welding. Since the pipes are stably supported on multiple pipe support assemblies 5 and the lifting assembly 3 ensures the stability of the support plate 4 and the pipes, the pipes will not shake during the welding process, ensuring the precision and quality of the welding.
