[0025] It has the advantages of stably supporting and clamping the pipe during welding, and can also drive the welded pipe to rotate, so as to facilitate subsequent welding.

[0026] Among them, the inner side of the roller group 38 is rotatably connected to the first roller, one end of the first roller is keyed to the motor, the inner wall of the support seat 33 is rotatably connected to the second roller, and vertical rods 39 are fixedly installed at both ends of the top of the cross plate 34. The bracket 37 is slidably connected to the vertical rod 39, which can be driven by the motor to drive the pipeline to rotate when supporting and assisting in clamping, thereby facilitating rotary welding operations.

[0027] When welding:

[0028] Directly place the pipe on the support seat 33. The inner side wall of the support seat 33 is rotatably connected to the second roller and the second roller. Then, the first electric push rod 35 is operated. At this time, the first electric push rod 35 pulls the top plate 36 to drive the bracket 37 and the roller group 38 to move downward together, so that the first roller in the roller group 38 presses the pipe. The other end is operated in the same way as above. Then, the two groups of clamping mechanisms 3 and the two groups of pipes to be welded can be driven by the moving mechanism 2 to move together and make the two groups of pipes contact for welding. In the process of moving up and down, the bracket 37 will slide up and down on the outside of the vertical rod 39;

[0029] During the welding process, the motor is activated to drive the first roller to rotate, and the pressing force is used to drive the welded pipe to rotate slowly and evenly, so as to facilitate the rotation welding and improve the required welding efficiency and effect.

[0030] Preferably, the moving mechanism 2 includes a power assembly and a sliding assembly, the power assembly is arranged in the inner cavity of the bottom box 1, and the sliding assembly is arranged on the outside of the power assembly.

[0031] like Figure 3 As shown, the power assembly includes a partition 21, which is fixedly installed in the middle of the inner cavity of the partition 21, an electric slide 22 is fixedly installed between the partition 21 and the bottom box 1, and a mounting seat 23 is fixedly installed on the top of the moving end of the electric slide 22 to facilitate movement and position adjustment.

[0032] like Figure 3 As shown, the sliding assembly includes a connecting seat 24, which is fixedly installed on the outer side of the moving end of the electric slide 22. A cross bar 25 is fixedly installed on the inner wall of the partition 21. The connecting seat 24 is slidably connected to the cross bar 25, which plays a role of auxiliary support and transmission.

[0033] A slot 5 is formed at the top of the bottom box 1 , and the upper portion of the mounting seat 23 is slidably located inside the slot 5 , so as to limit the mounting seat 23 and enable the mounting seat 23 to move horizontally.

[0034] When the pipeline is butt-jointed;

[0035] When the electric slide 22 works, its moving end will drive the mounting seat 23 and the connecting seat 24 to move together. At this time, the connecting seat 24 will slide on the surface of the cross bar 25, and the mounting seat 23 will move inside the slot 5 while driving the connecting plate 31 and the components on its top and the welded pipes to move together until the two sets of pipes are in contact and ready for welding.

[0036] Furthermore, the shielding mechanism 4 includes an electric push rod 41, which is fixedly mounted on both sides of the bottom of the inner cavity of the bottom box 1. A shielding frame 42 is fixedly mounted on the output end of the electric push rod 41, and visible glass plates 43 are fixedly mounted on both ends of the shielding frame 42 to facilitate shielding and protecting the welding point.

[0037] When welding shielding:

[0038] The electric push rod 41 directly pushes the shielding frame 42 to move upward, and the shielding frame 42 and the visible glass plate 43 are located on the outside of the welding position, so that the welding position is shielded from front and back, thereby facilitating the observation of the welding process. The visible glass plate 43 uses special welding glass, which can be used to resist sparks, high temperature and strong light during welding.

[0039] At the same time, the waste slag and waste materials generated by welding will also fall into the shielding frame 42 and be collected, so as to play a role in auxiliary collection.
