Description

Technical Field

[0001] This utility model relates to the field of spray coating technology, specifically a pipeline spray coating robot. Background Technology

[0002] Steel pipelines are vital channels in the production and operation of petroleum and chemical industries, oil gathering and transportation, and water and gas supply systems, with a wide range of applications and extremely large consumption. To improve the corrosion resistance of steel pipelines and extend their service life, it is usually necessary to treat the inner and outer surfaces of the pipelines and apply an anti-corrosion coating. Currently, various anti-corrosion coating methods are used on-site for steel pipes. Among them, epoxy powder coated steel pipes are increasingly used and in growing demand due to their excellent mechanical properties, acid and alkali resistance, corrosion resistance, and other advantages.

[0003] Existing epoxy powder coating equipment for steel pipes has some drawbacks. For example, most existing epoxy powder coating equipment for steel pipes requires manual operation, which often results in uneven and incomplete coating. It is also inconvenient to adjust the coating according to the diameter of the steel pipe, which hinders the installation and use of the coating equipment.

[0004] Therefore, it is necessary to design a pipeline spraying robot to address the above problems. Utility Model Content

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.

[0030] Please see Figures 1-4 One embodiment provided by this utility model:

[0031] A pipe spraying robot, comprising:

[0032] A first frame 1 is provided, and a second frame 2 is provided on the outside of the first frame 1. A first sealing plate 3 and a second sealing plate 4 are respectively installed on the first frame 1 and the second frame 2. An output pipe 5 is installed on the first sealing plate 3. A connecting pipe 6 is rotatably connected to the end of the output pipe 5 away from the first sealing plate 3. A first gear 7 is fixed on the surface of the connecting pipe 6. A second gear 8 is meshed with the edge of the first gear 7. A first servo motor 9 is installed on the second gear 8. A spray head 10 is installed at the end of the connecting pipe 6 away from the output pipe 5. A feeding pipe 16 is installed on both the first sealing plate 3 and the second sealing plate 4. Spray nozzles 11 are evenly installed on the surface of the spray head 10. The spray head 10 is interconnected with the feeding pipe 16 through the connecting pipe 6 and the output pipe 5, which facilitates the transportation of the spray paint between the feeding pipe 16, the output pipe 5, the connecting pipe 6 and the spray head 10, and is conducive to the uniform spraying of the spray paint through the spray nozzles 11.

[0033] The first adjusting rod 12 is installed on the first frame 1. The end of the first adjusting rod 12 located outside the first frame 1 is equipped with a frame 14, and a walking wheel 15 is installed on the frame 14.

[0034] The second adjusting rod 18 is mounted on the second frame 2. The second servo motor 19 is provided on the outside of the second frame 2. The second servo motor 19 is mounted on the surface of the second sealing plate 4. The output end of the second servo motor 19 is equipped with a third adjusting rod 20.

[0035] In one embodiment, the first adjusting rods 12 are distributed at equal angles on the first frame 1, and the first adjusting rods 12 are connected to the first frame 1 by a through thread. When the first adjusting rods 12 are turned to rotate, the first adjusting rods 12 can be displaced and adjusted on the first frame 1 through the thread.

[0036] In one preferred embodiment, the first adjusting rod 12 is rotatably connected to the frame 14, and the frame 14 is symmetrically fixedly mounted with limiting rods 13. The limiting rods 13 are slidably connected to the first frame 1. When the first adjusting rod 12 is displaced, the first adjusting rod 12 can push the frame 14 to move synchronously, and the frame 14 can move stably through the cooperation between the limiting rods 13 and the first frame 1.

[0037] In one embodiment, the feeding tube 16 has a hollow structure and is fixedly connected to the first sealing plate 3. The feeding tube 16 and the second sealing plate 4 are connected by a through sliding connection, so that the feeding tube 16 can slide on the second sealing plate 4, and the sliding feeding tube 16 can push the first sealing plate 3 to move synchronously.

[0038] In one preferred embodiment, the second adjusting rod 18 is distributed at equal angles on the second frame 2, and the second adjusting rod 18 and the second frame 2 are connected by a through thread. When the second adjusting rod 18 is turned to rotate, the second adjusting rod 18 can be displaced on the second frame 2 through the thread, which is conducive to the second adjusting rod 18 pressing against the inner wall of the pipe.

[0039] In one preferred embodiment, a guide plate 17 is installed at the end of the feeding pipe 16 away from the first sealing plate 3. The third adjusting rod 20 and the guide plate 17 are connected by a through thread. When the third adjusting rod 20 rotates, the third adjusting rod 20 can push the guide plate 17 to move through the thread, and at this time the guide plate 17 can push the feeding pipe 16 to move synchronously.

[0040] The working principle of this utility model is as follows: the first frame 1 and the second frame 2 are respectively placed at the openings at both ends of the pipe. Then, the first adjusting rod 12 and the second adjusting rod 18 are screwed on respectively. The first adjusting rod 12 is displaced on the first frame 1 through the thread. The first adjusting rod 12 pushes the frame 14 to drive the traveling wheel 15 to press against the inner wall of the pipe. The second adjusting rod 18 is also displaced on the second frame 2 through the thread until the end of the second adjusting rod 18 is also pressed against the inside of the pipe. This is conducive to the stable installation of the first frame 1 and the second frame 2 in the pipe, which facilitates the subsequent spraying work.

[0041] The external paint delivery pipe is connected to the feed pipe 16. The paint is injected into the spray head 10 through the feed pipe 16, the output pipe 5, and the connecting pipe 6, and sprayed out through the spray nozzle 11. At this time, the second servo motor 19 is started to drive the third adjusting rod 20 to rotate. The third adjusting rod 20 pushes the guide plate 17 through the thread to move the feed pipe 16. The feed pipe 16 moves on the second sealing plate 4, and the feed pipe 16 will drive the first sealing plate 3 to move synchronously. The first sealing plate 3 will drive the output pipe 5, the connecting pipe 6, and the spray head 10 to move synchronously, which is conducive to the spray head 10 spraying along the pipe. The first servo motor 9 drives the connecting pipe 6 and the spray head 10 to rotate and spray through the second gear 8 and the first gear 7, which is conducive to uniform spraying of the inner wall of the pipe.

[0042] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
