Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically a welding device for pipeline installation. Background Technology

[0002] Welding in pipeline installation refers to a method of connecting pipelines using welding technology. Welded connections are one of the most commonly used connection methods in pipeline installation. Their main characteristics are strong and durable joints, high sealing performance, and no need for frequent maintenance. They are widely used in various industrial fields, such as oil, chemical, and natural gas transportation, and can ensure the sealing and pressure resistance of pipelines.

[0003] The "Welding Device for Pipe Installation" disclosed in application number "202323333268.0" includes a base and a support plate. The support plate is located on top of the base.

The guide posts 1806 and guide sleeves 20 can guide the bracket 1803 and prevent the bracket 1803 from tilting.

[0031] In this embodiment, preferably, support bars 14 are fixedly provided on both sides of the bottom end of the slide block 8, and two guide rails 13 are fixedly provided on the other side of the top end of the base plate 1. The support bars 14 are slidably connected to the guide rails 13. A support plate 15 is fixedly provided on the other side of the top end of the base plate 1. A horizontal hydraulic cylinder 12 is fixedly installed on one side of the support plate 15. The telescopic rod of the horizontal hydraulic cylinder 12 is fixedly connected to a support plate 16. The top end of the support plate 16 is fixedly connected to one side of the bottom end of the slide block 8. Vertical plates 21 are fixedly provided on both sides of the top end of the base plate 1. The two sides of the bottom end of the top plate 17 are respectively fixedly connected to the top ends of the two vertical plates 21. A mounting groove 22 is provided on one side of 21. The slide 8 can be guided by the support bar 14 and the guide rail 13 to maintain the linear movement of the slide 8. The slide 8 can be supported by the horizontal cylinder 12 to maintain its stability. By controlling the extension and retraction of the extension rod of the horizontal cylinder 12, the slide 8 can be pushed to move horizontally, which facilitates the adjustment of the distance between the welding assembly 9 and the pipe, and can meet the needs of pipes of different diameters. The vertical plate 21 can provide support between the top plate 17 and the bottom plate 1. The mounting groove 22 of the vertical plate 21 can increase the mounting space of the pipe, which is convenient for loading and unloading.

[0032] In use, the pipe is first placed on the roller 3, and the weld of the pipe is located at the operating port 5. The operating port 5 increases the operating space and facilitates pipe alignment. The mounting groove 22 of the vertical plate 21 increases the mounting space of the pipe and facilitates the loading of the pipe. Then, the vertical cylinder 1801 of the limiting component 18 drives the support 1803 to descend, so that the pressure roller 1804 is in contact with the pipe, which can limit the pipe and improve the stability of the pipe. The guide post 1806 and the guide sleeve 20 can guide the support 1803 and prevent the support 1803 from tilting, and maintain the positional accuracy between the pressure roller 1804 and the pipe.

[0033] After the pipeline is fixed, the staff adjusts the height of the lifting platform 901 using the vertical hydraulic cylinder 11 so that the height of the welding torch 903 corresponds to the height of the pipeline. During the adjustment process, the guide sleeve 10 and the guide column 904 guide the lifting platform 901 to prevent it from tilting and prevent the vertical hydraulic cylinder 11 from bearing radial force. After the welding torch 903 is adjusted, the horizontal hydraulic cylinder 12 pushes the slide block 8 to adjust the distance between the welding torch 903 and the pipeline, so that the welding torch 903 fits the weld seam of the pipeline and can weld the pipeline.

[0034] During the pipe welding process, the pipe is located between two idler rollers 3 in a central position. The operator drives one of the idler rollers 3 to rotate via motor 7. One of the idler rollers 3 can drive the synchronous pulley 401 of the transmission component 4 to rotate. The synchronous pulley 401 can drive the synchronous pulley 402 to rotate via synchronous belt 403, which in turn can drive the other idler roller 3 to rotate, ensuring the synchronicity of the two idler rollers 3. The idler roller 3 can drive the pipe to rotate, which is convenient for rotating the weld joint and performing circumferential welding on the pipe. The rubber pad 6 can increase the friction between the pipe and the idler roller 3, making it less likely for the pipe to slip.

[0035] After the pipe is welded, the horizontal hydraulic cylinder 12 retracts the slide block 8, and then the vertical hydraulic cylinder 1801 lifts the support bracket 1803, so that the pipe can be removed from the idler roller 3.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
