Description

Technical Field

[0001] The utility model relates to the technical field of pipeline spraying, in particular to a spraying device for wear-resistant and anti-corrosion coating on the outer wall of a pipeline. Background Art

[0002] Pipeline anti-corrosion coatings refer to coatings that are evenly and densely applied on the surface of rust-removed metal pipelines to isolate them from various corrosive media, which is one of the most basic methods for pipeline anti-corrosion. There are many varieties of anti-corrosion coatings, and their properties and uses are different. Among them, the coating technology is to form a continuous covering layer of insulating material on the metal surface to insulate between the metal and the electrolyte in direct contact with it (preventing the electrolyte from directly contacting the metal), that is, to set a high resistance so that the electrochemical reaction cannot occur normally. And the coating will also increase the wear-resistant performance of the outer wall of the pipeline. After retrieval, the Chinese patent with the publication number CN209918160U discloses a spraying device for wear-resistant and anti-corrosion coating on the outer wall of a pipeline, including a pipeline rotation unit, a moving spraying unit and a spraying machine. When in use, the pipeline rotation unit can clamp pipelines with different diameters and lengths and can control the rotation speed of the pipeline to meet the requirements of spraying rotation speed. By moving the moving spraying unit along the axial direction of the pipeline and cooperating with the rotation of the pipeline, the spraying of the outer wall of the pipeline is realized. The spraying is uniform and bubble-free, and a uniform wear-resistant and anti-corrosion thin film layer can be formed on the outer wall of the pipeline, improving the spraying quality and anti-corrosion effect and extending the anti-corrosion period of the pipeline. However, its pipeline rotation unit is set separately, which is not convenient to drive the pipeline to rotate synchronously when passing through the bottom of the spraying device. The pipeline rotation unit and the moving trolley need to cooperate to complete the uniform spraying of the outer wall of the pipeline. If the cooperation is not good, it is easy to cause the situation of uneven spraying thickness. Therefore, a spraying device for wear-resistant and anti-corrosion coating on the outer wall of a pipeline is designed, which is convenient to drive the pipeline to rotate while passing through the lower part of the spraying structure, so that the pipeline obtains a uniform wear-resistant and anti-corrosion thin film layer and further ensures the spraying uniformity.

A spraying structure is provided at the top of the gantry 1. Multiple groups of pipeline clamping structures are horizontally and spaced apart on the pipeline moving bracket 2. The pipeline clamping structure includes two groups of symmetrically arranged tapered pipeline clamping blocks 4 that are respectively rotatably connected to both sides of the pipeline moving bracket 2. And rotating gears 5 are fixedly installed on multiple tapered pipeline clamping blocks 4 on one side, and multiple tapered pipeline clamping blocks 4 on the other side are all connected to the pipeline moving bracket 2 through a horizontal feeding mechanism. And a rotating tooth belt 6 that can mesh with the rotating gear 5 is horizontally and fixedly connected to the bottom of the gantry 1.

[0025] Specifically, a moving driving structure for driving the horizontal movement of the pipeline moving bracket 2 through the gantry 1 is further provided at the bottom of the gantry 1. The moving driving structure is provided in two groups and is respectively arranged on both sides of the bottom of the gantry 1. The moving driving structure includes a moving gear 8 rotatably connected to the gantry 1. Moving tooth belts 9 that can mesh with the moving gear 8 are horizontally and fixedly installed on both sides of the bottom of the pipeline moving bracket 2. Moving motors 10 for driving the rotation of the moving gear 8 on the same side are fixedly installed on both sides of the bottom of the gantry 1. Through the moving driving structure, it is convenient to drive the pipeline moving bracket 2 to penetrate under the gantry 1 at a certain speed, ensuring the uniformity of spraying and pipeline rotation. Start the moving motor 10 to make the output shaft of the moving motor 10 rotate, thereby driving the rotation of the moving gear 8. Through the meshing of the moving gear 8 and the moving tooth belt 9, the pipeline moving bracket 2 can be driven to penetrate under the gantry 1 at a certain speed. Further, the moving motor 10 can be set as a speed-regulating motor, and the speed of the pipeline moving bracket 2 can be adjusted accordingly according to the different diameters of the pipelines, so as to control the spraying thickness.

[0026] Specifically, the spraying structure includes a wear-resistant and corrosion-resistant spraying liquid tank 11 fixedly installed on the top of the gantry 1. A pressure pump 12 is fixedly installed on the wear-resistant and corrosion-resistant spraying liquid tank 11. The input end of the pressure pump 12 extends into the inner bottom of the wear-resistant and corrosion-resistant spraying liquid tank 11 through a connecting pipe. The output end of the pressure pump 12 is fixedly connected with a plurality of spraying branch pipes 13 through a spraying main pipe. A plurality of spraying branch pipes 13 all fixedly penetrate through the gantry 1 and are fixedly connected with a plurality of spraying caps 14 located below the top of the gantry 1 and facing downward. Starting the pressure pump 12 facilitates introducing the wear-resistant and corrosion-resistant spraying liquid in the wear-resistant and corrosion-resistant spraying liquid tank 11 into the plurality of spraying branch pipes 13 through the spraying main pipe and spraying it out through the plurality of spraying caps 14, so as to spray the pipeline passing below the spraying structure.

[0027] Specifically, a plurality of valves 15 are installed on one side of the spraying main pipe far away from the rotating toothed belt 6, and the plurality of valves 15 are cross-set at the position between two adjacent spraying branch pipes 13. Through the valves 15, it is convenient to open and close the influence when the pipeline length changes, so as to ensure that the whole pipeline can be sprayed without wasting the wear-resistant and corrosion-resistant spraying liquid.

[0028] Specifically, the horizontal feeding mechanism includes an adjusting screw 7 threadedly connected to the pipeline moving bracket 2. The adjusting screw 7 is rotatably connected to the conical pipeline clamping block 4 on the same side. One end of the adjusting screw 7 far away from the conical pipeline clamping block 4 is fixedly installed with an adjusting knob. By rotating the adjusting knob, the adjusting screw 7 can be driven to rotate, so as to be threadedly connected with the pipeline moving bracket 2, and then the conical pipeline clamping block 4 can be driven to move horizontally. Furthermore, according to the length of the pipeline, the pipeline can be clamped between two opposite conical pipeline clamping blocks 4, and at the same time, it is convenient to disassemble the pipeline after spraying. Further, an outward protruding groove 16 through which the adjusting screw 7 can penetrate is provided on one side of the gantry 1, and the gantry 1 and the pipeline moving bracket 2 are horizontally guided and slidably matched, which is convenient for the pipeline moving bracket 2 to stably penetrate through the gantry 1 horizontally.

[0029] Specifically, a plurality of rollers 3 are fixedly installed at the bottom of the pipeline moving bracket 2. Through the plurality of rollers 3, it is convenient for the pipeline moving bracket 2 to move.

[0030] During use, first clamp a plurality of pipelines in multiple groups of pipeline clamping structures in sequence. Both ends of each pipeline are clamped by the conical pipeline clamping blocks 4 inserted into the pipeline interior. Then, push the pipeline moving bracket 2 into the gantry 1 from one side. After being pushed in, due to the meshing of the rotating gear 5 and the rotating toothed belt 6, the conical pipeline clamping block 4 is driven to rotate, thereby driving the pipeline to rotate, and the spraying structure sprays the rotating pipeline. Then, after passing through the other side of the gantry 1, replace the pipeline moving bracket 2 that clamps a plurality of pipelines with another group of pipeline moving brackets 2, and then the above operations can be repeated.
