[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-6 As shown, a welding device suitable for large-diameter water transmission steel pipes includes two sets of guide rails 1 installed on both sides of the large-diameter water transmission steel pipe. The two sets of guide rails 1 abut together and are connected by an installation assembly to form a ring structure. The guide rails 1 are slidably connected to a support base 14.

[0030] Preferably, the support base 14 has an adjustment groove 26 at its top, and an adjustment seat 15 is slidably connected to the inner wall of the adjustment groove 26. The top of the adjustment seat 15 is fixedly connected to the welding tool 18. For large-diameter water supply steel pipes of different sizes, the welding tool 18 is moved, and the welding tool 18, along with the adjustment seat 15, slides along the inner wall of the adjustment groove 26. The welding tool 18 can drive the welding wire 20 to move to the outer wall of the large-diameter water supply steel pipe.

[0031] Preferably, the inner wall of the adjusting groove 26 is engaged with the adjusting seat 15, and the inner wall of the adjusting groove 26 provides stable support for the welding tool 18 by abutting against the adjusting seat 15. When the welding tool 18 moves with the adjusting seat 15, the inner wall of the adjusting groove 26 provides stable support for the welding tool 18 by abutting against the adjusting seat 15.

[0032] Preferably, the adjusting seat 15 has an adjusting screw hole 17 along its axis, and an adjusting rod 16 is threadedly connected to the inner wall of the adjusting screw hole 17. The side end of the adjusting rod 16 is rotatably connected to the support seat 14. When the welding fixture 18 moves, the adjusting rod 16 is controlled to rotate, and the adjusting rod 16 drives the adjusting seat 15 to move through the threaded connection with the inner wall of the adjusting screw hole 17.

[0033] Preferably, a rotating wheel 25 is fixedly connected to the side end of the adjusting rod 16, and a rubber sleeve is fitted onto the outer wall of the rotating wheel 25. The rubber sleeve increases friction, making it easier to control the rotation of the rotating wheel 25, which in turn drives the adjusting rod 16 to rotate.

[0034] Preferably, the mounting assembly includes a mounting plate 21, a side plate 22, a mounting post 23, and a nut 24; the mounting plate 21 and the side plate 22 are respectively fixedly connected to two sets of guide rails 1, the side end of the mounting post 23 is fixedly connected to the mounting plate 21, and the nut 24 is threadedly connected to the outer wall of the mounting post 23 and abuts against the side plate 22.

[0035] Preferably, the side end of the guide rail 1 is fixedly connected to the connecting seat 4, the connecting seat 4 has a rotating groove 12 inside, the inner wall of the rotating groove 12 is rotatably connected to a rotating plate 11, the top end of the rotating plate 11 is fixedly connected to a threaded rod 6, and the threaded rod 6 is threadedly connected to a positioning component.

[0036] Preferably, the positioning assembly includes a limiting post 7, a positioning plate 8, and positioning holes 9; the positioning plate 8 has two sets of positioning holes 9 on its side, and a threaded hole 10 is provided at the end of the positioning plate 8 away from the positioning holes 9. The inner wall of the threaded hole 10 is threadedly connected to the threaded rod 6. The bottom end of the limiting post 7 is fixedly connected to the connecting seat 4. Rectangular cross-section limiting grooves are provided on both sides of the threaded hole 10. The inner wall of the limiting groove is slidably engaged with the limiting post 7. An operating handle 61 is provided at the top of the threaded rod 6.

[0037] In the above technical solution, before the two sets of guide rails 1 are installed on the large-diameter water supply steel pipe, the positioning component is installed on the ground. Specifically, the positioning plate 8 is first placed on the ground, and then the wedge is inserted into the ground through the positioning hole 9 to fix the positioning plate 8. Then, by rotating the operating handle 61, the threaded rod 6 is controlled to rotate, which in turn drives the rotating plate 11 to rotate along the inner wall of the rotating groove 12. At the same time, the threaded rod 6 moves upward or downward along the threaded hole 10. Therefore, the threaded rod 6 moves vertically and drives the connecting seat 4 to move vertically through the rotating plate 11. Finally, the connecting seat 4 aligns the guide rail 1 and installs it on one side of the large-diameter water supply steel pipe.

[0038] The working steps of this utility model are as follows:

[0039] First, align the two sets of large-diameter water supply steel pipes and then fix them with clamps. Guide rails 1 are set on both sides of the large-diameter water supply steel pipes. Before welding the large-diameter water supply steel pipes, clean the outer surface of the large-diameter water supply steel pipes. A bearing shell 3 is fixedly connected to the side of the guide rail 1. The bearing shell 3 is used to hold the tools for cleaning the surface of the large-diameter water supply steel pipes. Before welding the large-diameter water supply steel pipes, the cleaning tools remove dust from the surface of the large-diameter water supply steel pipes.

[0040] The second step involves installing the two sets of guide rails 1 on both sides of the large-diameter water supply steel pipe. The two sets of guide rails 1 abut together to form a ring. The upper and lower ends of the guide rails 1 are fixed with installation components, which are used to fix the two sets of guide rails 1 together. Before the two sets of guide rails 1 abut together, one set of guide rails 1 is fixed by the positioning component. Specifically, before the two sets of guide rails 1 are installed on the large-diameter water supply steel pipe, the positioning component is installed on the ground. Specifically, the positioning plate 8 is placed on the ground first, and then the wedge is inserted into the ground through the positioning hole 9 to fix the positioning plate 8. Then, by rotating the operating handle 61, the threaded rod 6 is controlled to rotate, which in turn drives the rotating plate 11 to rotate along the inner wall of the rotating groove 12. At the same time, the threaded rod 6 moves up or down along the threaded hole 10. Therefore, the threaded rod 6 moves vertically and drives the connecting seat 4 to move vertically through the rotating plate 11. Finally, the connecting seat 4 aligns and installs the guide rail 1 on one side of the large-diameter water supply steel pipe.

[0041] When one set of guide rails 1 is installed on one side of the large-diameter water transmission steel pipe, another set of guide rails 1 is installed on the other side of the large-diameter water transmission steel pipe, and the two sets of guide rails 1 are supported against each other. When the two sets of guide rails 1 are installed on the large-diameter water transmission steel pipe, the side plate 22 has a round hole, the mounting column 23 passes through the round hole, and the nut 24 is threaded onto the side plate 22, connecting the mounting plate 21 and the side plate 22 together, and further connecting the two sets of guide rails 1 together.

[0042] Thirdly, for large-diameter water supply steel pipes of different sizes, the welding tool 18 is moved. The welding tool 18, along with the adjusting seat 15, slides along the inner wall of the adjusting groove 26. The welding tool 18 moves the welding wire 20 to the outer wall of the large-diameter water supply steel pipe. The inner wall of the adjusting groove 26 is engaged with the adjusting seat 15. When the welding tool 18 moves with the adjusting seat 15, the inner wall of the adjusting groove 26 provides stable support for the welding tool 18 by resisting the adjusting seat 15. When the welding tool 18 moves, the adjusting rod 16 is rotated. The adjusting rod 16 moves the adjusting seat 15 through a threaded connection with the inner wall of the adjusting screw hole 17. A rotating wheel 25 is fixedly connected to the side end of the adjusting rod 16. The wall sleeve is connected with a rubber sleeve, and the rotating wheel 25 is controlled to rotate. The rotating wheel 25 drives the adjusting rod 16 to rotate. The welding wire 20 abuts against the outer wall of the large-diameter water supply steel pipe. The control support 14 rotates along the axis of the large-diameter water supply steel pipe. The support 14 carries the welding tool 18 to rotate. The welding tool 18 drives the welding wire 20 to rotate against the outer wall of the large-diameter water supply steel pipe. The welding wire 20 welds the outer wall of the large-diameter water supply steel pipe. The top of the welding tool 18 is fixedly connected to a sensor 19. The sensor 19 can detect the welding quality of the large-diameter water supply steel pipe. The side end of the guide rail 1 is fixedly connected to a display 5. The sensor 19 transmits the detected data to the display 5 for display.

[0043] Fourth step: When the support seat 14 drives the slide plate 13 to slide along the inner wall of the groove 2, the guide rail 1 can provide guidance for the movement of the support seat 14. When the welding tool 18 moves to the bottom of the large-diameter water supply steel pipe with the welding wire 20, the welding tool 18 can control the welding wire 20 to accurately weld the bottom of the large-diameter water supply steel pipe through the support of the guide rail 1, avoiding the need for workers to lie down to operate, and at the same time, avoiding the occurrence of inaccurate welding by workers.

[0044] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
