Description

Technical Field

[0001] This invention relates to the field of pipe processing, and more specifically, to a pipe anti-corrosion coating equipment. Background Technology

[0002] Pipelines are widely used in many fields such as petroleum, chemical, and municipal engineering. Due to their long-term exposure to humid, corrosive media or atmospheric environments, they are prone to corrosion, leading to shortened pipeline lifespan, increased leakage risk, and even safety accidents. Therefore, applying anti-corrosion coatings to pipelines is a crucial protective measure. Currently, the application of anti-corrosion coatings to pipelines mainly relies on manual brushing, roller coating, or on-site spraying. Manual operation suffers from high labor intensity, low efficiency, difficulty in ensuring coating uniformity, and reliance on personnel skills for quality, easily resulting in defects such as uneven coating thickness, missed areas, or runs. Furthermore, for coating long pipeline sections, traditional methods often require multiple moves of the pipeline or construction equipment, making the process cumbersome and difficult to automate continuously and stably. Summary of the Invention

[0003] The purpose of this invention is to provide a pipeline anti-corrosion coating equipment, which solves the problems of high labor intensity, low efficiency, difficulty in ensuring coating uniformity, and quality dependence on personnel skills in pipeline anti-corrosion coating.

[0004] To achieve the above objectives, the present invention provides a pipeline anti-corrosion coating equipment, which includes a platform inclinedly mounted on a support. A first clamp assembly and a second clamp assembly for placing a pipeline are respectively fixed on the platform, allowing the pipeline to rotate on the first clamp assembly and the second clamp assembly. A spray pipe is fixed on the support, and multiple nozzles are spaced apart on the spray pipe. Multiple drainage channels are provided inside the platform, and a recovery channel communicating with the drainage channels is provided on the lower side of the platform. One end of the recovery channel is connected to a discharge pipe.

[0005] Preferably, the first clamping assembly includes a first support fixed on the platform, a drive motor fixed on the first support, and a first positioning post connected to the output shaft of the drive motor, so that the pipe can be inserted into the first positioning post.

[0006] Preferably, a first limiting ring is provided in the middle of the first positioning post.

[0007] Preferably, a protective shell is provided on the first support, and the drive motor is located inside the protective shell.

[0014] This invention provides a pipeline anti-corrosion coating equipment. The equipment includes a platform tilted on a support, with a first clamp assembly and a second clamp assembly fixed to the platform, allowing the pipeline to rotate on these assemblies. A spray pipe is fixed to the support, with multiple nozzles spaced apart on the spray pipe. Multiple drainage channels are provided within the platform, and a recovery tank communicating with the drainage channels is located on the lower side of the platform. One end of the recovery tank is connected to a discharge pipe.

The first clamping assembly directly drives the first positioning post to rotate via the drive motor, providing stable and controllable rotational power for the pipe. This direct drive method ensures uniform circumferential rotation of the pipe during the coating process and adjustable speed, thereby guaranteeing the uniformity and consistency of the sprayed coating and greatly improving the coating quality and automation level.

[0021] In a preferred embodiment of the present invention, a first limiting ring 74 is provided at the center of the first positioning post 73. The first limiting ring, located at the center of the first positioning post, provides reliable axial positioning of the pipe end fitted onto it. This effectively prevents axial movement of the pipe during high-speed rotation, ensuring the stability of the pipe position during spraying, thus improving spraying accuracy and enhancing equipment operational safety.

[0022] In a preferred embodiment of the present invention, a protective shell 72 is provided on the first support 71, and the drive motor is located inside the protective shell 72.

The second clamping assembly uses a slidable push rod to support the second positioning post, enabling the equipment to quickly adapt to pipes of different lengths. The distance between the two clamping assemblies can be adjusted by simply pushing or pulling back, achieving rapid and flexible adaptation to different pipe lengths, significantly improving the versatility of the equipment and the efficiency of pipe replacement operations.

[0024] In a preferred embodiment of the present invention, a slide rail is formed on the second support 81, and the push rod 82 is slidably disposed within the slide rail. A locking screw 83 is screwed onto the second support 81, such that the locking screw 83 can contact the push rod 82. The cooperative design of the slide rail and the locking screw allows the position of the push rod to be continuously adjusted and to be securely locked at any desired position.

[0025] In a preferred embodiment of the present invention, in order to facilitate the collection of excess liquid, the pipe anti-corrosion coating device further includes a housing 13, and the discharge pipe 10 is at least partially located inside the housing 13.

[0026] In a preferred embodiment of the present invention, in order to facilitate the recycling of the anti-corrosion spray liquid inside the box, a pump body 11 is provided on the box body 13, the inlet pipe 12 of the pump body 11 is located inside the box body 13, and the outlet pipe 9 of the pump body 11 is connected to the spray pipe 5.
