[0002] Steel pipes, as an important structural material and fluid transport carrier, are widely used in construction, bridges, petrochemicals, municipal engineering, and machinery manufacturing due to their high strength, good toughness, and ease of processing. In these applications, the connection of steel pipes is crucial, and welding is one of the most common and reliable connection methods. High-quality welded joints not only require defect-free welds but also precise positioning and secure fixing of the steel pipes before welding. This is a prerequisite for ensuring weld quality, structural strength, and operational safety.

[0003] Traditional welding methods rely on manual support and simple clamps. This method not only requires multiple people to work together, consuming a lot of manpower and time, but is also prone to displacement and shaking of the steel pipe during the welding process due to human factors or external interference, resulting in welding misalignment and uneven welds, thus affecting the welding quality of the steel pipe. At the same time, it requires multiple people to work together, resulting in insufficient welding efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 4 The present invention provides a technical solution: a steel pipe welding auxiliary fixing tool, including a base plate 1, an adjusting plate 2 whose position is adjustable along the length direction of the base plate 1 on one side, the adjusting plate 2 is restricted to move by a positioning mechanism, a positioning plate 3 is fixedly connected to the upper surface of the base plate 1 to position the steel pipe, and a first fixing plate 4 and an extension plate 5 are fixedly connected to the upper surface of the adjusting plate 2.

[0024] Both the positioning plate 3 and the first fixing plate 4 have a clamping mechanism fixedly connected to one side to fix the steel pipe.

[0025] One side of the extension plate 5 is provided with a vertical fixing mechanism to fix the steel pipe in the vertical direction.

[0026] During the sliding process, the adjusting plate 2 can align the first fixed plate 4 or the extension plate 5 above with the positioning plate 3. When the first fixed plate 4 is aligned with the positioning plate 3, welding can be performed on the coaxial steel pipes. When the extension plate 5 is aligned with the positioning plate 3, welding can be performed on the mutually perpendicular steel pipes. The welding direction can be adjusted by sliding the adjusting plate 2, and the movement of the adjusting plate 2 can be restricted by the positioning mechanism. The positioning mechanism limits the position of the adjusting plate 2 to prevent the positioning plate 3 from shaking during the welding process. The clamping mechanism presses on the upper surface of the steel pipe. The clamping mechanism can fix the two sections of steel pipe on the positioning plate 3 and the first fixed plate 4 respectively, making the welding more stable and reducing the shaking that occurs during the welding process.

[0027] In this embodiment, as a preferred solution, the positioning mechanism includes a positioning pin 6 and a positioning hole 7. The positioning hole 7 is opened on the upper surface of the base plate 1. The positioning pin 6 passes through the adjusting plate 2 and is inserted into the positioning hole 7. A guide rail 8 arranged along the length direction is fixedly connected to the upper surface of the base plate 1. The adjusting plate 2 is slidably guided to the guide rail 8.

[0028] When the adjusting plate 2 slides to the extreme positions on both sides, the holes on the adjusting plate 2 will align with the positioning holes 7 on the base plate 1. At this time, the positioning pin 6 can be inserted into the positioning hole 7 to fix the relative position of the adjusting plate 2 and the base plate 1, preventing the adjusting plate 2 from moving during the welding process. The guide rail 8 limits the movement direction of the adjusting plate 2, making the sliding of the adjusting plate 2 more stable.

[0029] In this embodiment, as a preferred option, the clamping mechanism includes a support rod 9, an adjusting rod 10, and a pressure plate 11. The support rod 9 is fixedly connected to the upper surface of the base plate 1 and located on one side of the positioning plate 3. The adjusting rod 10 is threadedly connected to the top of the support rod 9. The pressure plate 11 is rotatably connected to the bottom of the adjusting rod 10 via a rotating shaft. The pressure plate 11, the positioning plate 3, and the first fixing plate 4 all have V-shaped cross sections. One side of the positioning plate 3 is provided with a notch for welding.

[0030] When the adjusting rod 10 is rotated, it pushes the bottom pressure plate 11 to move, causing the pressure plate 11 to move towards or away from the positioning plate 3, thereby fixing or loosening the steel pipe on the positioning plate 3. When the pressure plate 11 and the positioning plate 3 move towards each other, their cross-sections are both V-shaped, thus clamping the steel pipe in the middle. While fixing, the axis of the steel pipe is determined. The first fixing plate 4 has the same V-shape, which allows the axis of the steel pipe to be positioned directly during welding, further improving welding efficiency. The notch avoids the welding position of the steel pipe, making welding more convenient. The top of the support rod 9 at the positioning plate 3 can be rotated. After the vertical steel pipe is welded, the top of the support rod 9 can be rotated to easily remove the steel pipe.

[0031] In this embodiment, as a preferred option, the vertical fixing mechanism includes a threaded rod 12, a push plate 13, and a second fixing plate 14. The threaded rod 12 is threadedly connected to the middle of the extension plate 5. The push plate 13 is rotatably disposed at one end of the threaded rod 12. The second fixing plate 14 is fixedly connected to one side of the push plate 13 to fix the vertical steel pipe. A connecting rod 15 is fixedly connected to one side of the extension plate 5. The connecting rod 15 is L-shaped, and an auxiliary clamping plate 16 is fixedly connected to the end of the connecting rod 15 away from the extension plate 5.

[0032] Rotating the threaded rod 12 will push the push plate 13 to one side. When the push plate 13 moves, it will drive the second fixing plate 14 to move. The second fixing plate 14 and the auxiliary clamping plate 16 can fix the vertical steel pipe. With the positioning plate 3, the horizontal steel pipe can be fixed, and the mutually perpendicular steel pipes can be welded.

[0033] In this embodiment, as a preferred option, angle irons 17 are fixedly connected to the outer surfaces of both the positioning plate 3 and the first fixing plate 4, and the angle irons 17 are fixedly connected to the upper surfaces of the base plate 1 and the adjusting plate 2, respectively.

[0034] Angle iron 17 is supported on the outside of positioning plate 3 and first fixing plate 4 to increase the strength of first fixing plate 4 and reduce deformation during the fixing of steel pipe.

[0035] In this invention, the working steps of the device are as follows:

[0036] 1. When welding coaxial steel pipes, place the two steel pipe sections above the positioning plate 3 and the first fixing plate 4 respectively, so that the joint of the two steel pipe sections is in the notch on the positioning plate 3. Rotate the adjusting rod 10 to move the pressure plate 11 down, so that the pressure plate 11 presses on the steel pipe. After fixing the steel pipe, weld it. After the upper welding is completed, loosen the pressure plate 11, rotate the steel pipe at a certain angle, and weld the bottom of the steel pipe. After the joint is fully welded, loosen the pressure plate 11 and take out the steel pipe.

[0037] 2. When welding mutually perpendicular steel pipes, first pull out the positioning pin 6, slide the position of the adjusting plate 2 to align the second fixing plate 14 with the positioning plate 3. After alignment, insert the positioning pin 6 into the positioning hole 7 to fix the position of the adjusting plate 2. After fixing, place the vertical steel pipe between the auxiliary clamping plate 16 and the second fixing plate 14, rotate the threaded rod 12 to move the second fixing plate 14 and the auxiliary clamping plate 16 towards each other to fix the vertical steel pipe. After fixing, fix the horizontal steel pipe on the positioning plate 3. After fixing the two sections of steel pipe, weld the joint. After the surface welding is completed, remove the steel pipe and then weld the bottom of the steel pipe that is not visible.
