Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for pipeline welding, specifically an anti-silt sealing device for auxiliary welding of river pipelines. Background Technology

[0002] In pipeline trenching construction in river channels and coastal areas, problems such as silt accumulation and tidal changes are frequently encountered. When conducting pipeline welding work in river environments, the large amount of silt carried by the water flow can severely interfere with the welding process. Once silt enters the welding area, it leaves impurities at the weld joint, reducing the strength and sealing of the weld, thereby shortening the service life of the pipeline and resulting in low efficiency and poor sealing of traditional pipeline connections. Water accumulation in the welding pit requires repeated pumping, affecting construction efficiency. Therefore, those skilled in the art have provided an anti-silt sealing device for auxiliary river pipeline welding to solve the problems mentioned in the background art. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the present invention, an anti-siltation sealing device for auxiliary welding of river pipelines includes a first anti-siltation component 1 and a second anti-siltation component 4. The first anti-siltation component 1 and the second anti-siltation component 4 are arranged opposite to each other and have the same structure.

[0021] The first anti-sludge component 1 has a back plate 2 on its rear side, and a rear channel 3 is opened below the back plate 2 to provide space for the pipe 20 to be welded to pass through. A side plate 9 is provided on one side of the first anti-sludge component 1, and a transverse butt plate 10 extends from the middle of the side plate 9. A slide rail 11 is installed at the end of the transverse butt plate 10 for cooperating with the sealing pressure plate 8. A bottom plate 6 is provided at the bottom of the first anti-sludge component 1, and a front semi-circular arc groove 7 is provided in the middle of the bottom plate 6. Its size matches the butt semi-circular arc groove 15 at the bottom of the sealing pressure plate 8. The second anti-sludge component 4 has the same structure as the first anti-sludge component 1. After the two are set opposite each other, they can be connected and fixed by the first fixing seat 17, the second fixing seat 19 and the pin 18.

[0022] The upper end of the sealing pressure plate 8 is provided with a lifting lug 12 for easy hoisting operation; sliders 13 are provided on both side walls, and the sliders 13 engage with the slide rails 11 at the ends of the transverse docking plates 10 to realize the sliding adjustment of the sealing pressure plate 8 between the two transverse docking plates 10; the bottom docking semi-circular arc groove 15 corresponds to the front semi-circular arc groove 7 of the bottom plate 6, and together they can wrap around the pipe 20 to be welded; a shock-absorbing block 14 is also provided on one side of the docking semi-circular arc groove 15 to reduce the vibration generated during the sealing process.

[0023] Sealing rings 16 are installed on the inner walls of the rear channel 3, the front semi-circular groove 7, and the connecting semi-circular groove 15. When the sealing plate 8 slides into place and the connecting semi-circular groove 15 and the front semi-circular groove 7 are joined to form a circular structure that wraps around the pipe 20, the sealing rings 16 will tightly fit the surface of the pipe 20, forming a multi-layer sealing barrier, effectively preventing sludge from seeping into the welding area from the contact gap between the device and the pipe. At the same time, the gap reserved between the two transverse connecting plates 10 is the same as the width of the sealing plate 8, ensuring that the sealing plate 8 can slide smoothly and connect precisely, further ensuring the sealing effect.

[0024] The working principle of this utility model is as follows: In use, the first anti-sludge component 1 and the second anti-sludge component 4 are first placed on both sides of the pipe 20 to be welded, so that the pipe 20 passes through the rear channel 3 below the back plate 2. Then, the first fixing seat 17 and the second fixing seat 19 are connected by the pin 18 to complete the fixing of the first anti-sludge component 1 and the second anti-sludge component 4.

[0025] Next, the sealing plate 8 is lifted using the lifting lug 12 of the docking plate, and slides on the slide rail 11 via the slider 13, so that the docking semi-circular groove 15 at the bottom of the sealing plate 8 aligns with the front semi-circular groove 7 on the base plate 6, thus enclosing the pipe 20 within the sealed space formed by the front semi-circular groove 7, the docking semi-circular groove 15, and the rear channel 3. At this time, the sealing protective ring 16 on the inner wall tightly adheres to the pipe 20, forming a sealed environment to prevent silt from entering. At this point, workers can weld the pipe 20 within the space between the back plate 2 and the transverse docking plate 10.

[0026] After welding is completed, reverse the above steps: first slide away the sealing pressure plate 8, then pull out the pin 18 to disassemble the device, which is convenient and quick.
