Description

Technical Field

[0001] This utility model relates to the field of steel pipe anti-corrosion treatment technology, specifically to a spraying equipment for anti-corrosion steel pipes. Background Technology

[0002] Anti-corrosion steel pipes, as a type of steel pipe with excellent corrosion resistance, are essentially processed using professional anti-corrosion technology to form an effective protective layer on the pipe surface. This significantly inhibits or delays chemical or electrochemical corrosion caused by contact with air, moisture, and chemical media during long-term transportation, installation, and actual use. Consequently, they greatly extend the service life of the pipes and reduce maintenance costs. They are widely used in many fields with strict requirements for pipeline corrosion resistance, such as petroleum, natural gas, water supply and drainage, and chemical industries. In the production and processing of anti-corrosion steel pipes, spraying is one of the key processes for achieving anti-corrosion protection. Currently, the industry mostly uses spray guns as the main spraying tool. Although this method can achieve rapid coating coverage, in actual operation, because the freshly sprayed coating has not been fully cured, it has a certain degree of fluidity. Under the combined influence of gravity and factors such as the flatness of the pipe surface and the uniformity of the coating thickness, the coating is prone to flowing down and accumulating on the pipe surface, resulting in a "sagging" problem. This sagging phenomenon not only leads to uneven thickness of the anti-corrosion coating on the pipe surface, but also causes bubbles and cracks in some areas due to coating accumulation, and some areas may lose their protective function due to coating loss, directly affecting the anti-corrosion effect and the appearance quality of the pipe. It also causes coating waste and increases the manpower and time costs of subsequent repair processes. Therefore, the existing spray gun-based anti-corrosion steel pipe spraying process still has obvious defects, and there is an urgent need for technical optimization and improvement to address the sagging problem.

A clamping frame 501 is provided on the mounting plate 5. The mounting frame 3 is installed inside the spraying device housing 1. A second drive motor 301 is installed inside the mounting frame 3. A lead screw 302 is installed on the output shaft of the second drive motor 301. The spraying equipment housing 1 is provided with an adjustment frame 4, on which a spray gun 6 and a frame 7 are provided. A roller 701 is installed inside the frame 7. A first bracket 603 and a second bracket 703 are welded on the adjustment frame 4. A connecting frame 201 is installed on the first drive motor 2. The end of the connecting frame 201 facing away from the first drive motor 2 is installed on the outer shell 1 of the spraying equipment. The first drive motor 2 is securely installed on the outer shell 1 of the spraying equipment through the connecting frame 201. A third hydraulic rod 502 is installed on the mounting plate 5. The output shaft of the third hydraulic rod 502 is connected to the clamping frame 501. By utilizing the telescopic characteristics of the third hydraulic rod 502, the position of the clamping frame 501 can be adjusted so that it can adapt to steel pipes of different diameters, realize reliable clamping of steel pipes, and prevent steel pipes from falling off or shifting due to rotation or movement during the spraying process, thereby improving the versatility and safety of the equipment. A guide block 401 is welded onto the adjusting frame 4. The guide block 401 is slidably sleeved inside the mounting frame 3. The guide block 401 is threadedly mounted on the lead screw 302. The guide block 401 provides a stable guiding function for the movement of the adjusting frame 4, ensuring that the adjusting frame 4 can only move smoothly along the direction of the mounting frame 3. At the same time, the guide block 401 is threadedly connected to the lead screw 302, so that when the second drive motor 301 drives the lead screw 302 to rotate, it can be converted into the left and right movement of the adjusting frame 4, realizing the adjustment of the position of the spray gun 6 and the frame 7. A first hydraulic rod 601 is installed on the first bracket 603. The output shaft of the first hydraulic rod 601 is connected to the spray gun 6. An external pipe 602 is installed on the spray gun 6. The first hydraulic rod 601 can flexibly adjust the position of the spray gun 6, so that the spray gun 6 can be adjusted to the optimal spraying distance and angle according to the diameter of the steel pipe and the spraying requirements, thereby improving the spraying quality. The external pipe 602 can be easily connected to an external anti-corrosion coating supply device to ensure a continuous supply of coating and ensure the continuous operation of the spraying operation. The anti-corrosion coating supply device can also supply anti-corrosion coating by drawing it from the pump body. The bottom end face of the second support 703 is equipped with a second hydraulic rod 702. The output shaft of the second hydraulic rod 702 is connected to the frame 7. The height of the frame 7 and the roller 701 can be adjusted by the extension and retraction of the second hydraulic rod 702, so that the roller 701 can be adjusted to a suitable position according to the diameter of the steel pipe and contact the steel pipe. During the rotation and spraying process of the steel pipe, the roller 701 can perform roller coating on the surface of the steel pipe, effectively avoiding the occurrence of paint dripping and improving the flatness and quality of the sprayed surface. Furthermore, the first drive motor 2, the second drive motor 301, the spray gun 6, the first hydraulic rod 601, and the second hydraulic rod 702 of the spraying equipment can all be controlled by external control switches connected via wires. The power supply control principle and circuit connection method of the external control panel are common functional module designs, and are common knowledge in the fields of electrical automation control and mechanical equipment. The relevant technologies are widely used and their principles are clear, therefore, no further elaboration is necessary.

[0025] Working principle: Steel pipe placement stage: The operator places the anti-corrosion steel pipe to be sprayed inside the outer shell 1 of the spraying equipment, so that one end of the steel pipe contacts the end face of the mounting plate 5, which lays the foundation for subsequent fixing and spraying. Steel pipe clamping and fixing stage: Start the third hydraulic rod 502 on the installation plate 5. The output shaft of the third hydraulic rod 502 pushes the clamping frame 501 to move towards the steel pipe until the clamping frame 501 firmly clamps the outer wall of the steel pipe, so as to realize the adaptation and fixing of steel pipes of different diameters and prevent the steel pipe from falling off or shifting during the spraying process. Spraying preparation stage: The spray gun 6 is connected to the external anti-corrosion coating supply equipment through the external pipe 602 on the spray gun 6 to ensure that the coating can be stably delivered to the spray gun 6; at the same time, the first hydraulic rod 601 on the first bracket 603 can be activated to adjust the position and angle of the spray gun 6 by extending and retracting the first hydraulic rod 601, so that the spray gun 6 is aligned with the area to be sprayed on the steel pipe to achieve the best initial state for spraying. Full coating stage: Start the first drive motor 2. The output shaft of the first drive motor 2 drives the mounting plate 5 to rotate, which in turn drives the clamped steel pipe to rotate synchronously, providing conditions for the full circumference of the steel pipe to be sprayed. Start the second drive motor 301 inside the mounting bracket 3. The second drive motor 301 drives the lead screw 302 to rotate. Since the guide block 401 on the adjusting bracket 4 is both slidably sleeved in the mounting bracket 3 and connected to the lead screw 302 through threads, the rotation of the lead screw 302 will be converted into the smooth left and right movement of the adjusting bracket 4, which in turn drives the spray gun 6 to move along the length of the steel pipe. Combined with the rotation of the steel pipe, a comprehensive and uniform spraying of the steel pipe surface is achieved. Assisted anti-sagging stage: During the spraying process, the rotating steel pipe helps reduce sagging, allowing the paint to adhere evenly to the steel pipe. Personnel can activate the second hydraulic rod 702 at the bottom of the second support 703. The output shaft of the second hydraulic rod 702 pushes the frame 7 upward, causing the roller 701 inside the frame 7 to contact the outer wall of the steel pipe. As the steel pipe rotates and the adjusting frame 4 moves, the roller 701 rolls synchronously, rolling and flattening the paint just sprayed on the surface of the steel pipe, effectively preventing the paint from sagging due to gravity and improving the smoothness of the sprayed surface.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
