Its main function is to transport various fluid media, such as oil, natural gas, chemical raw materials, etc., while preventing pipeline damage due to corrosion, extending the service life of the pipeline, and ensuring the safety and stability of the transportation process.

[0003] In order to make the anti-corrosion pipeline more durable, a reinforcement ring for reinforcing the anti-corrosion pipeline is usually welded on the outside of the anti-corrosion pipeline, but most of the existing reinforcement rings are welded manually, and the processing efficiency is low. Summary of the invention

[0004] In order to improve the welding efficiency of the reinforcement ring, the present application provides a welding structure for the outer surface reinforcement ring of an anti-corrosion pipe.

[0005] The above technical objectives of this application are achieved through the following technical solutions: A welding structure for a reinforcement ring on the outer surface of an anti-corrosion pipe comprises a frame, two semicircular supports for supporting the anti-corrosion pipe are arranged above the frame, the axes of the two semicircular supports are the same, and a fixing structure for fixing the reinforcement ring is arranged between the two semicircular supports, welding guns for welding the reinforcement ring are arranged on both sides of the fixing structure, semicircular arc slide rails are arranged on both sides of the reinforcement ring, and an arc slide rod is slidably connected in the arc slide rail, and the welding gun is connected to one end of the arc slide rod.

[0006] By adopting the above scheme, when it is necessary to weld the reinforcement ring, the anti-corrosion pipe and the fixed ring are placed on the frame, the anti-corrosion pipe is placed on the semicircular support, and the reinforcement ring is fixed by a fixed structure. The welding gun is started, and the arc-shaped slide rod slides in the arc-shaped slide groove at the same time, thereby driving the welding gun to move along the anti-corrosion pipe, so as to weld the connection between the reinforcement ring and the anti-corrosion pipe, thereby improving the efficiency of the welding of the anti-corrosion pipe reinforcement ring.

[0007] Optionally, the fixed structure includes a bidirectional screw, a groove is formed on the upper surface of the frame, the bidirectional screw is rotatably connected in the groove, and a first motor is connected to one end of the bidirectional screw, the output shaft of the first motor is fixedly connected to the bidirectional screw, two sliders are threadedly connected to the bidirectional screw, the two sliders are slidably connected in the groove, and the two sliders are respectively located at opposite ends of the bidirectional screw, when the bidirectional screw rotates, the two sliders approach or move away from each other, and a clamp is fixedly connected above the slider, and the two clamps clamp the reinforcement ring.

[0008] By adopting the above scheme, the rotation of the first motor drives the bidirectional screw to rotate, thereby driving the two sliders closer to each other, and then driving the two clamps closer to each other, so that the two clamps clamp the reinforcement ring, thereby fixing the reinforcement ring and making the welding of the reinforcement ring smoother.

[0009] Optionally, the clamping plates are semicircular in shape, and a U-shaped groove is provided on the surface of one of the clamping plates, and a support block with the same shape as the U-shaped groove is provided on the surface of the other clamping plate opposite the U-shaped groove. The support block is used to support the reinforcement ring, and when the two clamping plates clamp the reinforcement ring, the support block is inserted into the U-shaped groove.

[0010] By adopting the above scheme, when welding the reinforcement ring, the anti-corrosion pipe and the reinforcement ring are placed on the frame, and the reinforcement ring is placed on the support block, so that the support block supports the reinforcement ring, and the axis of the support ring and the anti-corrosion pipe coincide, thereby making the reinforcement ring smoother during welding.

[0016] By adopting the above scheme, the rotation of the second motor drives the rectangular rod to rotate, thereby driving the driving gear to rotate, and the driving gear drives the arc-shaped sliding rod and the arc-shaped rack to slide, thereby driving the welding gun to rotate around the pipeline, and the rectangular tube passes through two driving gears with the same axis, so that the rotation speed of the two driving gears is the same, and then the welding gun speeds on both sides of the reinforcement ring are the same, so that the welding effect of the reinforcement ring and the anti-corrosion pipeline is better.

[0019] Optionally, the fixing plate is an arc-shaped fixing plate.

[0020] By adopting the above solution, the contact area between the arc-shaped fixing plate and the anti-corrosion pipeline is larger, and the force on the pipeline is made more uniform, thereby making the pipeline more firmly fixed.
