[0002] Oil and gas pipeline surface grinding devices are highly efficient equipment specifically designed for oil and gas pipeline maintenance. Through automated or semi-automated operation, equipped with grinding tools of different specifications, they can quickly remove impurities such as rust, welding slag, and old coatings from the pipeline surface. Precise control of grinding force and depth ensures that the pipeline surface achieves ideal roughness and cleanliness standards, effectively improving the adhesion of subsequent anti-corrosion coatings and guaranteeing the long-term stable operation of oil and gas pipelines. They are widely used in pipeline construction, inspection, and maintenance.

[0003] Oil and gas pipeline surface grinding equipment is a specialized piece of equipment developed to meet the surface treatment needs of oil and gas transmission pipelines. It is mainly used to remove impurities such as oxide scale, welding slag, rust layer and old coating from the pipeline surface, laying the foundation for subsequent anti-corrosion and inspection processes. In oil and gas pipeline engineering, the quality of surface treatment directly affects the protective effect of the anti-corrosion layer, and grinding equipment, as a key piece of equipment, is developing towards intelligence, lightweight and multi-functional integration.

[0004] The above-mentioned device has the following drawbacks: sandblasting and grinding generate a large amount of dust, and if the dust collection system is inefficient, the dust concentration in the working environment can easily exceed the standard (e.g., exceeding 8 mg / m³). 3 This poses a risk of splashing when mechanically grinding high-speed rotating parts, which endangers the health of operators. Therefore, a surface grinding device for oil and gas pipelines is proposed to solve the above problems. Utility Model Content

If the dust removal system is inefficient, it can easily cause the dust concentration in the working environment to exceed the standard (e.g., exceeding 8 mg / m³). 3 This poses a health risk to operators.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a surface grinding device for oil and gas pipelines, comprising a pipeline body and a sliding sleeve plate, wherein the sliding sleeve plate is slidably connected to the outer side wall of the pipeline body, an auxiliary mechanism is provided on the sliding sleeve plate, and an adjustment mechanism is provided on the auxiliary mechanism, wherein the auxiliary mechanism includes an upper cover frame, the upper cover frame is fixedly connected to the outer side wall of the sliding sleeve plate, a slide opening is provided on the top inner wall of the upper cover frame, a support frame is fixedly connected to the top outer wall of the upper cover frame, a grinding machine body is slidably connected to the left inner wall of the support frame, a grinding disc is fixedly connected to the output of the grinding machine body through a coupling, a lower cover frame is in contact with the bottom outer wall of the upper cover frame, a positioning frame is fixedly connected to the top inner wall of the lower cover frame, an adjustment plate is slidably connected to the top inner wall of the positioning frame, a clamping plate is fixedly connected to the front outer wall of the adjustment plate, and a compression spring is fixedly connected to the rear outer wall of the adjustment plate.

[0007] As a further description of the above technical solution: the adjustment mechanism includes transparent glass, which is fixedly connected to the top inner wall of the upper cover frame. The bottom inner wall of the lower cover frame has an installation port. The inner ring of the installation port is threaded with a threaded cylinder. The bottom inner wall of the threaded cylinder is rotatably connected to a flexible hose through a bearing. The right end of the flexible hose is fixedly connected to the vacuum cleaner body.

[0008] As a further description of the above technical solution: the grinding disc contacts the outer side wall of the pipe body, and the grinding machine body penetrates the inner wall of the slide opening.

[0009] As a further description of the above technical solution: the positioning frame penetrates the bottom inner wall of the upper cover frame, and frosted pads are fixedly connected to the left and right outer walls of the adjustment plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of an oil and gas pipeline surface grinding device, comprising a pipeline body 1 and a sliding sleeve 2. The sliding sleeve 2 is slidably connected to the outer side wall of the pipeline body 1. An auxiliary mechanism 3 is provided on the sliding sleeve 2, and an adjustment mechanism 4 is provided on the auxiliary mechanism 3. The auxiliary mechanism 3 includes an upper cover 31, which is fixedly connected to the outer side wall of the sliding sleeve 2. The sliding connection between the sliding sleeve 2 and the outer side wall of the pipeline body 1 allows the grinding device to move along the axial direction of the pipeline body 1, thereby achieving grinding treatment on different positions of the surface of the pipeline body 1, effectively expanding the grinding range, and improving the flexibility and applicability of the grinding. A slide opening 32 is provided on the top inner wall of the upper cover 31, and a support is fixedly connected to the top outer wall of the upper cover 31. The frame 34 has a grinding machine body 35 slidably connected to its left inner wall. The output of the grinding machine body 35 is fixedly connected to the grinding disc 36 via a coupling. The bottom outer wall of the upper cover 31 contacts the lower cover 37. The sliding sleeve 2 is slidably connected to the outer side wall of the pipe body 1, allowing the grinding device to move along the axial direction of the pipe body 1, thereby achieving grinding treatment on different positions of the surface of the pipe body 1, effectively expanding the grinding range and improving the flexibility and applicability of grinding. The top inner wall of the lower cover 37 is fixedly connected to a positioning frame 38. The top inner wall of the positioning frame 38 is slidably connected to an adjusting plate 39. The front outer wall of the adjusting plate 39 is fixedly connected to a clamping plate 310, and the rear outer wall of the adjusting plate 39 is fixedly connected to a compression spring 311.

[0024] Reference Figures 2-4 The grinding disc 36 contacts the outer side wall of the pipe body 1. The grinding machine body 35 penetrates the inner wall of the slide 32. The grinding disc 36 contacts the outer side wall of the pipe body 1. The surface of the pipe body 1 is ground by the rotation of the grinding disc 36 to remove rust, impurities, etc., so that the surface of the pipe reaches the required smoothness and precision to meet the needs of subsequent use. The positioning frame 38 penetrates the bottom inner wall of the upper cover frame 31. The left and right outer walls of the adjusting plate 39 are fixedly connected with abrasive pads. The abrasive pads increase the friction between the adjusting plate 39 and the inner wall of the positioning frame 38, preventing the adjusting plate 39 from sliding freely in the positioning frame 38, and ensuring that the adjusting plate 39 can be adjusted to the appropriate position. To maintain stability, the engagement between the clamping plate 310 and the upper cover frame 31 is made more secure. There are two adjusting plates 39, which are symmetrically opposite each other. The two ends of the compression spring 311 are fixedly connected to the outer side walls of the two adjusting plates 39. The clamping plate 310 contacts the outer side walls on both sides of the upper cover frame 31. The positioning frame 38 passes through the outer side walls on both sides of the upper cover frame 31. Wear-resistant pads are fixedly connected to the outer side walls of the clamping plate 310. The wear-resistant pads improve the wear resistance of the clamping plate 310, extend its service life, and ensure the reliability of the engagement between the clamping plate 310 and the upper cover frame 31. Even after multiple installation and disassembly operations, the good engagement effect can still be maintained.

[0025] Reference Figures 3-4 The adjustment mechanism 4 includes a transparent glass 41, which is fixedly connected to the top inner wall of the upper cover 31. This allows the operator to observe the internal grinding process of the device from the outside, such as the working status of the grinding disc 36 and the grinding progress of the surface of the pipe body 1. This facilitates timely detection and adjustment of problems, improving the accuracy and efficiency of the grinding work. The bottom inner wall of the lower cover 37 has an installation port 42. A threaded cylinder 43 is threadedly connected to the inner wall of the inner ring of the installation port 42. A flexible hose 44 is rotatably connected to the bottom inner wall of the threaded cylinder 43 via a bearing. The right end of the flexible hose 44 is fixedly connected to the vacuum cleaner body 45. The flexible hose 44 is connected to the lower cover 37. A directional mark is provided on the bottom outer wall of the threaded cylinder 43. The directional mark helps the operator accurately determine the installation direction when installing the threaded cylinder 43, ensuring the correct connection between the threaded cylinder 43 and the lower cover 37, and avoiding the impact on the vacuuming effect or the device malfunctioning due to incorrect installation direction.

[0026] Working principle: The upper cover 31 and lower cover 37 are attached to the outer wall of the pipe body 1 by sliding the sliding sleeve plate 2. At the same time, the positioning frame 38 passes through the left and right outer walls of the upper cover 31, and the clamping plate 310 is engaged with the left and right outer walls of the upper cover 31, so that the upper cover 31 and lower cover 37 are in contact with each other. Then, the grinding machine body 35 is turned on to rotate the grinding disc 36. At the same time, the transparent glass 41 allows observation of the inside. Then, the grinding disc 36 rotates to grind the outer wall of the pipe body 1. At the same time, when the grinding machine body 35 is adjusted, the upper cover 31 and lower cover 37 are driven to move. 7. Rotate or move the adjustment together to wrap the powder generated during grinding and reduce splashing. At the same time, turn on the main body of the vacuum cleaner 45 to suck in the dust inside the lower cover 37 and the upper cover 31. Meanwhile, the slide port 32 introduces air from the outside to prevent a vacuum from forming inside when the main body of the vacuum cleaner 45 sucks up the powder. After grinding the outer wall, pull the adjustment plate 39 to move the clamping plate 310. The clamping plate 310 moves and separates from the left and right outer walls of the upper cover 31. Then pull the lower cover 37 to separate the positioning frame 38 from the upper cover 31, which is convenient for personnel to quickly disassemble and assemble on other pipes.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
