Technical Field

[0001] This utility model relates to the field of pipe fitting auxiliary equipment technology, and more specifically, to an auxiliary device for steel pipe welding and thermal cutting flipping. Background Technology

[0002] In the field of steel pipe welding or thermal cutting, traditional welding methods and thermal cutting rely on manual operation of welding torches or cutting equipment moving back and forth around the circumference of the pipe. To ensure the welding or cutting quality of steel pipes during the welding or cutting process, operators usually need to have extremely rich operating experience, and the welding or cutting quality cannot be effectively guaranteed in the long term.

[0003] In existing technologies, during the welding or thermal cutting of pipe fittings, it is usually necessary to fix the steel pipe first before proceeding with the construction work. During construction, the steel pipe is first positioned and fixed; however, due to the varying sizes of the steel pipes, existing fixing devices are not very effective at securing them. Furthermore, after fixing the pipe fitting, flipping it over is difficult, resulting in discontinuous welding or thermal cutting, which affects the overall quality of the finished pipe fitting and has adverse effects on its later use.

[0023] Example

[0024] Please refer to Figures 1-4 As shown.

[0025] This utility model provides an auxiliary device for turning steel pipes during welding and hot cutting, such as... Figure 1 , Figure 2 As shown, the device includes a mounting base 1, which is welded from a steel frame. At least two sets of mounting seats 6 are mounted on the mounting base 1. Each mounting seat 6 has a ring-shaped mounting bracket 3. The mounting seats 6 and mounting brackets 3 are fixedly connected by bolts. Notches are provided on the side walls of the mounting brackets 3, thus giving the mounting brackets 3 a slightly curved shape, facilitating the entry of pipes of different sizes into the enclosed area formed by the mounting brackets 3, improving the adaptability of this structure to different pipes. An installation channel 15 is provided inside the mounting bracket 3. The installation channel 15 has a rectangular cross-section, thus eliminating the need for additional guide structures. The slide rail 9, which is slidably set in the installation channel 15, moves in a circular motion along the circle where the mounting frame 3 is located within the installation channel 15. The free end of the slide rail 9 is placed in the notch. The slide rail 9 is also arc-shaped. The slide rail 9 is equipped with a clamping component for clamping the pipe fitting, so that the pipe fitting placed in the mounting frame 3 will not move out of the mounting frame 3 during the flipping process. The mounting frame is equipped with a support component for supporting the pipe fitting, so that the pipe fitting can move smoothly in a circular motion within the mounting frame 3. This makes it convenient for the operator to rotate the pipe fitting to be welded or hot-cut later, so as to ensure the welding quality or hot-cutting quality of the pipe fitting.

[0026] Preferably, the mounting base 1 is equipped with a frame that can be fixed with bolts to stabilize the welding gun and the cutting end of the thermal cutter, thereby improving the stability of the pipe fittings to be welded or thermally cut when the operator operates the above-mentioned components.

[0027] Preferably, a plurality of locking holes are provided on the outer side wall of the mounting bracket 3, and a locking element 12 is provided in one of the locking holes to restrict the free movement of the slide rail 9 within the mounting channel 15.

[0028] In some technical solutions of this utility model, the clamping assembly includes an internal threaded hole opened on the free end of the slide rail 9, a limiting rod 5 threadedly connected to it in the internal threaded hole, and a limiting plate 10 rotatably connected to it on the limiting rod 5. The above structure facilitates the operator to manually operate the limiting plate 10 set on the limiting rod 5 to move it closer to the pipe placed in the mounting frame 3, and apply a top holding force to the pipe to restrict the pipe within the mounting frame 3.

[0029] In some technical solutions of this utility model, the support assembly includes two support frames 8 rotatably mounted at the bottom of the mounting frame 3, and each support frame 8 has a guide wheel 4 rotatably mounted on its free end. This ensures that the pipe fittings located inside the mounting frame 3 do not contact the inner wall of the mounting frame 3, allowing the pipe fittings to smoothly perform circular motion within the mounting frame 3 under the support of the two guide wheels 4; it also facilitates the operator to rotate the pipe fittings to be welded or thermally cut later, ensuring the welding quality or thermal cutting quality of the pipe fittings.

[0030] Preferably, the guide wheel 4 is equipped with a roller motor to ensure that the guide wheel can drive the pipe to rotate.

[0031] In some technical solutions of this utility model, two mounting openings are provided on the side wall of the mounting bracket 3. A rotating shaft is rotatably provided in each mounting opening. The two rotating shafts are respectively connected to two support brackets 8 by welding. A torsion spring connected to the inner wall of the mounting opening is sleeved on the rotating shaft. The support bracket 8 configured in this way can make a certain angle of deflection on the mounting bracket 3 through the rotating shaft and the torsion spring, so that the support bracket 8 does not make rigid contact with the pipe fitting. This allows the structure to support pipe fittings with larger diameters and improves the adaptability of the structure.

[0032] In some technical solutions of this utility model, a retaining seat is rotatably provided on the free end of the limiting rod 5 via a bushing. A wedge-shaped guide groove is provided on the side wall of the retaining seat. A guide strip 11 adapted to it is slidably provided in the guide groove. The guide strip 11 is connected to the limiting plate 10. The limiting plate 10 configured in this way can make a circular motion relative to the limiting rod 5 around the center of the circle where the mounting frame 3 is located, and fix the pipe in the mounting frame 3, so as to avoid the problem of poor fixing effect of this structure on the pipe.

[0033] In some technical solutions of this utility model, an arc-shaped surface is provided on the side wall of the limiting plate 10 that contacts the pipe, so that the contact area when the limiting plate 10 contacts the pipe is increased. Multiple blind holes are provided on the side wall of the arc-shaped surface, and a limiting spring 13 is provided in each blind hole. A limiting ball 14 that abuts against the limiting spring is rotatably provided in the blind hole. The above structure can avoid the problem of pipe wear caused by hard contact between the limiting plate 10 and the pipe.

[0034] In some technical solutions of this utility model, two guide rails 2 are provided on the side wall of the mounting base 1, and two limiting grooves 7 are respectively adapted to the guide rails 2 at the bottom of the mounting seat 6. This facilitates the operator to move any two adjacent mounting seats, allowing the structure to assemble pipe fittings of different lengths and improving the assembly effect of the structure.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
