The bottom plate 28 is fixedly connected to the support frame 1, and two symmetrically distributed track bodies 24 are fixedly connected to the bottom plate 28. Each track body 24 contacts a track wheel 22, and a track wheel axle 23 is rotatably connected in the track wheel 22. The two track wheel axles 23 A slide plate 25 is fixedly connected between them, and a support wheel side plate 26 is installed on the slide plate 25 through a bolt 213. The outer rotation of the bolt 213 is connected to the support wheel body 27, and the support wheel body 27 is in contact with the ring plate 7. A limit plate 214 is fixedly connected to the bottom plate 28, and a baffle 21 is fixedly connected to the limit plate 214. The baffle 21 can prevent the track wheel 22 from derailing. The submerged arc automatic welding machine 3 is installed on the slide plate 25, and an auxiliary rod 216 is fixedly connected to the slide plate 25. A pull rod 215 is fixedly connected to the auxiliary rod 216, and a spring 217 is arranged on the pull rod 215.

[0021] like Figure 1 , Figure 2 As shown, there are multiple support rollers 5 , and all of the multiple support rollers 5 are in contact with the catheter 6 . The design of the support rollers 5 supports and assists the rotation of the catheter legs 6 .

[0022] like Figure 5 As shown, a support wheel shaft ring 29 is fixedly connected to the support wheel body 27, the support wheel shaft ring 29 is in contact with the support wheel side plate 26, the support wheel shaft ring 29 is rotatably connected to the bolt 213, a limit plate 214 is fixedly connected to the bottom plate 28, and a baffle 21 is fixedly connected to the limit plate 214, the baffle 21 can prevent the track wheel 22 from derailing, and the design of the support wheel shaft ring 29 has a guiding effect on the rotation of the support wheel body 27.

[0023] like Figure 5 As shown, the slide plate 25 is in contact with a pad 210 , and the pad 210 is in contact with the support wheel side plate 26 . The pad 210 has a supporting effect on the support wheel side plate 26 through its design.

[0024] like Figure 3As shown, one end of the spring 217 is fixedly connected to the pull rod 215, and the other end of the spring 217 is fixedly connected to the limit plate 214. Through the design of the spring 217, the welding gun of the submerged arc automatic welding machine 3 can always be in contact with the ring plate 7.

At this time, the welding gun of the submerged arc automatic welding machine 3 is aimed at the junction of the conduit 6 and the ring plate 7 to perform the welding operation, and then rotate the conduit 6 and the ring plate 7. Since the end face of the conduit 6 is inclined, the movement trajectory of the ring plate 7 is not just one. At this time, the ring plate 7 drives the supporting wheel body 27 to slide, and the supporting wheel body 27 drives the slide plate 25 to slide left and right along the track body 24. The plate 25 drives the auxiliary rod 216 to move, the auxiliary rod 216 drives the pull rod 215 to move, the pull rod 215 stretches the spring 217, and the welding gun of the submerged arc automatic welding machine 3 is also driven by the ring plate 7. Due to the characteristics of the spring 217, the welding gun of the submerged arc automatic welding machine 3 always keeps in contact with the ring plate 7, so that the welding gun of the submerged arc automatic welding machine 3 can always keep consistent with the movement trajectory of the joint between the ring plate 7 and the conduit 6, ensuring the uniformity of the weld, and the welding tool 2 can weld the ring plate 7 and the conduit 6 together at one time, shortening the welding time, improving the welding quality, and improving the welding efficiency.
