A driving component is provided between the two support bases 1. The two pipes to be welded are fixed by the limiting components, and the welding position of the two pipes is placed in the middle of the main pipe 2. The welding groove 3 above the main pipe 2 facilitates welding of the pipe joint inside the main pipe 2. The driving component can simultaneously drive the rotating pipes 5 on both sides to rotate, thereby driving the internal pipe to rotate. By welding the rotating pipe, the weld seam of the pipe can be welded from all directions, and the synchronous rotation of the two pipes is achieved, increasing the success rate and efficiency of welding.

[0025] As a preferred technical solution of this embodiment, the two rotating tubes 5 are fixedly installed with plug rings 11 on their peripheral walls, and the inner walls of both ends of the main tube 2 are provided with annular grooves 12. The plug rings 11 are rotatably connected to the annular grooves 12. The rotating tubes 5 can achieve axial positioning between the rotating tubes 5 and the main tube 2 through the plug rings 11, thereby preventing the rotating tubes 5 from detaching from the main tube 2.

[0026] As a preferred embodiment, the driving assembly includes a motor 16 embedded and fixedly installed inside one of the support bases 1. The output end of the motor 16 is connected to a drive rod 17. An mounting plate 13 is fixedly installed between the two support bases 1. A rotating shaft 14 is rotatably installed on the mounting plate 13. First gears 15 are fixedly installed at both ends of the rotating shaft 14. Gear rings 6 are fixedly installed on both rotating tubes 5. The two gear rings 6 mesh with the two first gears 15 respectively. The rotation of the motor 16 can drive the drive rod 17 to rotate. The drive rod 17 can drive the rotating shaft 14 to rotate through two bevel gears. The rotating shaft 14 can drive the gear rings 6 to rotate simultaneously through the two gears at both ends, thereby driving the rotation of the two rotating tubes 5.

[0027] As a preferred technical solution of this embodiment, a second bevel gear 19 and a first bevel gear 18 are fixedly installed on the rotating shaft 14 and the drive rod 17, respectively, and the first bevel gear 18 and the second bevel gear 19 mesh with each other; the drive rod 17 drives the first bevel gear 18 to rotate, the first bevel gear 18 can drive the second bevel gear 19 to rotate, and the second bevel gear 19 can drive the rotating shaft 14 to rotate.

Furthermore, by adjusting the position of the clamping rings 9 clamping the pipe, the position of the pipe can be adjusted, thereby achieving precise docking of the two pipes.

[0029] As a preferred technical solution in this embodiment, the inner walls of the plurality of clamping rings 9 are provided with rubber pads 10; the rubber pads 10 can protect the surface of the welding ring and prevent the clamping rings 9 from causing wear to the pipeline.

[0030] As a preferred technical solution in this embodiment, a welding groove 3 is provided at the top of the main pipe 2; the welding groove 3 can open up the space above the main pipe 2, thereby facilitating the welding of the internal pipes.

[0031] As a preferred technical solution in this embodiment, the welding groove 3 is detachably connected to both sides of the support plate 4. The support plate 4 can increase the placement space on both sides of the main pipe 2, which is convenient for placing some welding materials and increases the convenience of the welding process. Since the support plate 4 is detachable, only one side of the support plate 4 can be installed, and the other side is convenient for the staff to stand and weld.
