[0025] Please see Figure 1-4 ,

[0026] Example 1: A zinc-coated steel grounding exothermic welding fixing fixture includes a support frame 1. The support frame 1 has first limiting grooves 2 symmetrically opened on both sides and a second limiting groove 3 opened on the side of the support frame 1. Two welding straightening components 4 are symmetrically arranged on the support frame 1. A welding limiting component 5 is arranged on the other side of the support frame 1. Several support screws 6 are evenly arranged at the bottom end of the support frame 1. A support base 7 is arranged at the bottom of the support screws 6. The support screws 6 are threaded into the top of the support base 7. A first connecting steel pipe 8 is inserted at the second limiting groove 3. A second connecting steel pipe 9 is inserted at the first limiting groove 2. An exothermic welding mold 10 is arranged on the upper side of the end of the first connecting steel pipe 8.

[0027] The welding straightening assembly 4 includes an L-shaped connecting plate 401 disposed inside the support frame 1. A limiting slide 402 is provided on the side of the L-shaped connecting plate 401. A first abutment plate 403 is provided on the side of the limiting slide 402. A connecting bolt 404 is vertically fixed on the side of the first abutment plate 403. The end of the connecting bolt 404 passes through the limiting slide 402. A first fastening nut 405 and a second fastening nut 406 are respectively fitted on the connecting bolt 404. A first fastening bolt 407 is threaded into the other side of the support frame 1. A second abutment plate 408 is rotatably connected to the end of the first fastening bolt 407. An outer connecting plate 409 is fixed to the bottom of the side of the first limiting groove 2. An adjusting bolt 410 is threaded into the middle of the outer connecting plate 409. A positioning support plate 411 is rotatably connected to the top of the adjusting bolt 410.

[0028] The welding limiting assembly 5 includes a steel pipe abutment plate 501 disposed on the side of the first connecting steel pipe 8. The side of the steel pipe abutment plate 501 is connected to the support frame 1 through a fixed connecting plate 502. A side connecting plate 503 is fixed on the support frame 1. A second fastening bolt 504 is threaded into the middle of the side connecting plate 503. The end of the second fastening bolt 504 is rotatably connected to a limiting push plate 505.

[0029] Example 2: The difference between this example and Example 1 is that the end of the first connecting steel pipe 8 and the middle part of the second connecting steel pipe 9 are perpendicular to each other.

[0030] This makes it easier to weld the first connecting steel pipe 8 and the second connecting steel pipe 9 together using the set exothermic welding mold 10.

[0031] Example 3: The difference between this example and Example 1 is that the sides of the first contact plate 403 and the second contact plate 408 are both arc-shaped, and the first contact plate 403 and the second contact plate 408 are both attached to the two sides of the second connecting steel pipe 9.

[0032] This makes the second connecting steel pipe 9 more stable as it passes through the first limiting groove 2.

[0033] Example 4: The difference between this example and Example 1 is that the sides of the fixed connecting plate 502 and the limiting push plate 505 are both arc-shaped, and the fixed connecting plate 502 and the limiting push plate 505 are both attached to the two sides of the first connecting steel pipe 8.

[0034] This ensures that both sides of the first connecting steel pipe 8 are limited and fixed by contact.

[0035] In this embodiment, in the existing exothermic welding process, how to accurately and efficiently fix the zinc-coated steel workpiece to be welded has become an important link affecting the welding quality and construction efficiency. Traditional operation methods mostly rely on manual support and positioning, which is not only labor-intensive, but also makes it difficult to ensure the absolute stability of the workpiece position during welding. Slight deviations may cause defects such as incomplete welding or misalignment at the welding point, making it difficult to guarantee the welding quality at the joint.

[0036] In summary, in specific implementation, when the user needs to weld the end of the first connecting steel pipe 8 to the vertical connection point of the second connecting steel pipe 9, the user first needs to pass the second connecting steel pipe 9 through the middle of the first limiting groove 2. By rotating the first fastening bolt 407, the end of the first fastening bolt 407 pushes the second abutment plate 408, and the second abutment plate 408 abuts against the side of the second connecting steel pipe 9. The other side of the second connecting steel pipe 9 is abutted and limited by the first abutment plate 403. Since the connecting bolt 404 on the side of the first abutment plate 403 passes through the limiting sliding joint 402, the position of the first abutment plate 403 on one side of the second connecting steel pipe 9 can be effectively adjusted, so that the side of the second connecting steel pipe 9 can be abutted by the first abutment plate 403. By rotating the first fastening nut 405 and the second fastening nut 406, the first abutment plate 403 is fixed to the side of the L-shaped connecting plate 401.

[0037] An outer connecting plate 409 is provided on the outer side of the first limiting groove 2. An adjusting bolt 410 is threaded into the middle of the outer connecting plate 409. When the adjusting bolt 410 is rotated, it can push the positioning support plate 411 upward, thereby effectively supporting the bottom of both ends of the second connecting steel pipe 9 and ensuring that the ends of the second connecting steel pipe 9 and the first connecting steel pipe 8 are on the same horizontal plane. This is more conducive to the welding and fixing of the ends of the first connecting steel pipe 8 and the second connecting steel pipe 9 by the exothermic welding mold 10.

[0038] The welding limiting component 5, located on the side of the first connecting steel pipe 8, has a steel pipe contact plate 501 and a limiting push plate 505 that cooperate to limit and abut the two sides of the first connecting steel pipe 8 that passes through the second limiting groove 3, so that it is in a stable state during welding and is perpendicular to the second connecting steel pipe 9. The support screw 6 is threaded into the support base 7, so that the support height between the bottom of the support frame 1 and the ground can be adjusted, and the support frame 1 can be adjusted horizontally as a whole, which can adapt to various uneven ground and make it easier to weld the first connecting steel pipe 8 and the second connecting steel pipe 9.
