Description

Technical Field

[0001] This utility model relates to the technical field of welding roller frames for petrochemical pipelines, and in particular to a welding roller frame for petrochemical pipelines. Background Technology

[0002] In the crucial petrochemical industry, pipelines continuously transport flammable, explosive, and highly corrosive media such as oil, natural gas, and various chemical raw materials every day. Any minor oversight can lead to catastrophic consequences. Therefore, precise and safe welding operations to achieve reliable connections, or careful removal of damaged sections, are essential procedures to ensure the smooth operation of the entire petrochemical production process, whether during pipeline installation and construction, regular maintenance and repair, or in specific situations such as sudden damage or process upgrades.

[0003] The existing device places the pipe on the roller during welding, but there is no limit on the front and rear sides, which may cause the two pipes to move away from each other during rotation, resulting in welding failure.

[0004] Therefore, we propose a welding roller frame for petrochemical pipelines to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide a welding roller frame for petrochemical pipelines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A welding roller frame for petrochemical pipelines includes: a base plate and two pipeline bodies. A workbench is fixedly connected to the top of the base plate. Two longitudinal plates are slidably connected to the top of the workbench. A semi-circular plate is fixedly connected to the top of each of the two longitudinal plates. Rollers are rotatably connected to the sides of the two semi-circular plates that are close to each other on the same side. The two pipeline bodies are movably abutted against the outside of the two rollers. A side plate is fixedly connected to the top of the base plate. Two crossbars are slidably connected to the left side of the side plate. A disc is rotatably connected to the sides of the two crossbars that are close to each other. The sides of the two discs that are close to each other are movably abutted against the sides of the corresponding pipeline bodies that are far apart from each other.

[0008] Preferably, the left side of the side plate is provided with a through groove, the inside of the side plate is provided with an internal groove, a bidirectional lead screw is rotatably connected inside the internal groove, trapezoidal plates are fixedly connected to the right sides of the two crossbars, the two trapezoidal plates are threaded onto the outside of the same bidirectional lead screw, a third motor is fixedly connected to the front side of the side plate, the output end of the third motor is fixedly connected to the front end of the bidirectional lead screw, and the left sides of the two trapezoidal plates are slidably connected inside the same through groove.

[0009] Preferably, the worktable is internally rotatably connected to a bidirectional threaded rod, and the bottom of each of the two longitudinal plates is fixedly connected to a convex plate. The two convex plates are threaded onto the outside of the same bidirectional threaded rod, and the top of the worktable is provided with a transverse groove. The two convex plates are slidably connected inside the same transverse groove.

[0014] In this utility model, a welding roller frame for petrochemical pipelines is described. By placing two pipeline bodies to be welded on top of two rollers, a second motor is activated to drive a bidirectional threaded rod to rotate, causing the two convex plates on both sides to move closer to each other, which in turn causes the two rollers on both sides to move closer to each other and clamp the two pipeline bodies. A third motor is activated to drive a bidirectional lead screw to rotate, causing the two trapezoidal plates on both sides to move closer to each other, which in turn causes the two crossbars and discs on both sides to move closer to each other and clamp the two sides of the two pipeline bodies.

[0015] In this utility model, a petrochemical pipeline welding roller frame is described. By starting the first motor, the right-side roller is driven to rotate. Furthermore, by driving the two pipeline bodies, the left-side roller is driven to rotate in the opposite direction. Then, the welding gun is started to weld the two pipeline bodies.

[0016] This utility model has a reasonable structural design. The combination of a crossbar, a disc, a third motor, and a trapezoidal plate enables the clamping function of the two pipe bodies at the front and rear, improving the stability of welding. The combination of a convex plate, a bidirectional threaded rod, a longitudinal plate, and rollers enables the clamping of pipe bodies of different diameters, improving the applicability and working efficiency of the device.
