[0002] With the acceleration of modern urbanization, gas has been widely used in daily life and industrial production as a clean and efficient energy source. The construction of gas pipelines in gas engineering is one of the important links to ensure the safe and stable supply of gas. Welding technology, as a key process for connecting gas pipelines, plays a vital role in the entire gas engineering construction. Traditional gas pipeline welding mainly relies on manual operation, which requires welders to have high professional skills and has strict requirements on environmental conditions.

[0003] Traditional manual welding methods are not only inefficient, but also easily affected by human factors, resulting in unstable welding quality. In the manual welding process, the welder's operating skills and experience directly affect the quality of the welded joint. Even experienced welders find it difficult to ensure that the quality of each weld is completely consistent. In addition, long working hours may cause welder fatigue, further increasing the risk of welding defects. At the same time, manual welding is relatively slow and cannot meet the requirements of rapid construction, especially in emergency repairs or large-scale pipeline laying, where the problem of inefficiency is more prominent. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of manual welding of gas pipelines, the purpose of the utility model is to provide a welding device for gas pipelines used in gas engineering.

The third fastening assembly and the fastening assembly on one of the sliders are both rotatably connected with an extension plate. A sleeve is slidably connected between the two extension plates, and the extension plates are threadedly connected with bolts.

[0006] As a further preferred embodiment, the fastening assembly includes a slide rail, a fixed block and a screw. The slide rails of the fastening assembly are two in number. The two slide rails are hingedly connected to each other. At least three fixed blocks are fixedly connected to the slide rails. The fixed blocks are threadedly connected to the screws. The slider and the slide rail are rotatably connected.

[0007] As a further preferred solution, the slide rails are all semicircular arc-shaped, and the two slide rails hinged to each other form a perfect circle.

[0008] As a further preferred solution, the fastening assembly also includes a clamping plate, and one end of the screw rod close to the center of the slide rail is connected to the clamping plate.

[0009] As a further preferred solution, it also includes a sliding seat, a slide plate and a mounting block. A sliding groove is opened on one side of the sliding rail. The sliding grooves on the two hinged sliding rails are connected to each other. The sliding seat is slidably connected in the sliding groove, the slide plate is slidably connected on the sliding seat, and at least two mounting blocks are rotatably connected on the slide plate.

[0010] As a further preferred solution, a handle is also included, and the handle is connected to a side of the slide away from the slide seat.

[0011] The beneficial effects are as follows: the utility model is provided with a fastening assembly, through which the pipeline is fixed, which can adapt to the welding of pipelines with different outer diameters, thereby improving the applicability of the utility model. A sliding seat, a slide plate and a mounting block are also provided, and the welding rod and the welding gun are respectively fixed on two mounting blocks.

[0017] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A welding device for gas pipelines used in gas engineering, such as Figure 1-Figure 4As shown, it includes a support plate 1, a slider 2, a fastening assembly, a sleeve 7, an extension plate 8 and a bolt 9. The number of fastening assemblies is three. Two sliders 2 are slidably connected to the top of the support plate 1. The support plate 1 can improve the bearing capacity and stability of the welding device to ensure that no shaking or deviation occurs during the welding process. The slider 2 can slide freely on the support plate 1 to adjust the welding position, improve the convenience of operation, and enhance the adaptability of the welding device. The top of the slider 2 is connected with a fastening assembly. The third fastening assembly and the fastening assembly on one of the sliders 2 are rotatably connected with an extension plate 8. The two extension plates 8 are slidably connected with a sleeve 7. The extension plates 8 are located inside the sleeve 7, and the extension plates 8 are threaded with bolts 9.

[0019] like Figure 1-Figure 3 As shown, the fastening assembly includes a slide rail 3, a fixed block 4, a screw 5 and a clamping plate 6. There are two slide rails 3 in the fastening assembly. The two slide rails 3 are hingedly connected to each other. The slide rails 3 are evenly spaced along the circumferential direction and are fixedly connected with at least three fixed blocks 4. The fixed blocks 4 are threadedly connected with screws 5. The slider 2 is rotatably connected to the slide rail 3. The slide rails 3 are semicircular in shape. The two hinged slide rails 3 form a perfect circle. The ends of the screws 5 close to the center of the slide rail 3 are fixedly connected with a clamping plate 6. The clamping plate 6 is made of flexible material, which can provide sufficient friction without scratching the outer wall of the pipe.

[0020] like Figure 1-Figure 4 As shown, it also includes a slide seat 10, a slide plate 11, a mounting block 12 and a handle 13. A slide groove 31 is opened on one side of the slide rail 3. The slide grooves 31 on the two slide rails 3 hinged to each other are connected to each other. The slide seat 10 is slidably connected in the slide groove 31. The slide seat 10 is slidably connected to the slide plate 11. At least two mounting blocks 12 are rotatably connected to the slide plate 11. After the angle of the mounting block 12 is adjusted, the mounting block 12 is fixed to the slide plate 11 by screws, and the handle 13 is fixedly connected to the side of the slide plate 11 away from the slide seat 10.

[0021] Initially, the welding rod and welding gun are fixed on the two mounting blocks 12 respectively, the mounting blocks 12 are rotated to adjust the welding gun to the best welding angle, and then the two mounting blocks 12 are fixed by screws. When it is necessary to weld a linear gas pipeline, the two pipelines to be welded are respectively passed through the two slide rails 3 on the slider 2, and the slide plate 11 is slid so that the welding gun and welding rod are close to the welding edge of the pipeline, thereby adjusting the distance between the welding gun and welding rod and the pipeline, so that the welding gun and welding rod can be accurately positioned according to the actual situation to ensure the welding quality, and then the screw 5 is rotated to make the clamping plate 6 close to the outer wall of the pipeline, thereby fixing the pipeline through the fastening assembly, which can adapt to different When welding pipes with the same outer diameter, slide the slider 2 to bring the two pipes closer to each other. When the two pipes are close to each other, the two pipes are welded under the action of the welding gun and the welding rod. Hold the handle 13 to slide the slide 10 along the slide groove 31, thereby realizing continuous welding of the gas pipeline. When the slide 10 slides one circle along the slide groove 31, the two pipes are welded to each other. The welding rod and the welding gun can be accurately positioned according to the actual situation to realize circumferential welding, ensure that each welding point can be evenly heated, and improve the welding quality. Then reverse the screw 5 to make it away from the center of the slide rail 3, and the clamping plate 6 no longer contacts the outer wall of the pipe. Then the pipe can be taken out of the fastening assembly.

[0022] When it is necessary to weld a curved gas pipeline, the two pipelines are respectively passed through the two fastening components connected to the extension plate 8, and then the pipelines are fixed by rotating the screw 5, the extension plate 8 is rotated, and then the extension plate 8 is slid away from each other to adjust the distance between the two extension plates 8, so that the third fastening component moves left and right close to the fastening component on the slider 2, so that the edges of the two pipelines are completely fitted, and then the third fastening component and the fastening component on the slider 2 are fixed to each other by screws, and then the curved gas pipeline is welded according to the above welding operation, thereby completing the welding process of the curved gas pipeline.
