Description

Technical Field

[0001] This utility model relates to the field of pipeline rust prevention, and more specifically, to a rust-preventive spraying device for metal pipeline surfaces. Background Technology

[0002] Pipeline rust prevention not only extends pipeline lifespan, improves safety and efficiency, but also reduces maintenance costs, maintains pipeline performance, beautifies the environment, and brings significant economic benefits. Therefore, pipeline rust prevention treatment is very important and necessary. Currently, anti-corrosion coatings, such as epoxy coatings, are commonly applied to the pipeline surface, effectively preventing rust. Both the inner and outer walls can be coated; commonly used coatings include amine-cured epoxy resins and polyamide epoxy resins.

[0003] Currently, many methods still involve manually applying anti-rust paint to the surface of pipes. To ensure even coating, the pipe needs to be rotated while applying the paint. This method is not only inefficient but also results in inconsistent coating quality. Therefore, we have made improvements and proposed an anti-rust spraying device for metal pipe surfaces. Utility Model Content

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0005] A rust-proof spraying device for metal pipe surfaces is used to improve the above-mentioned problems.

[0006] The present invention is as follows:

[0007] The system includes a base, on which a storage bin is mounted. A spraying mechanism is mounted on top of the storage bin. A first hydraulic cylinder is fixedly mounted on the base. An installation seat is fixedly mounted on the output end of the first hydraulic cylinder. A driving mechanism is provided on the side wall of the installation seat. A rotating column is rotatably connected inside the installation seat. A round rod is fixedly mounted on the rotating column. An installation column is fixedly mounted on the other end of the round rod. A sliding rod is slidably connected inside the installation column. A second hydraulic cylinder is also fixedly mounted on the rotating column. The output end of the second hydraulic cylinder is fixedly connected to the sliding rod. An installation plate is fixedly mounted on the other end of the sliding rod. An active connecting rod is hinged to the installation plate. An outer support plate is hinged to the other end of the active connecting rod. An anti-slip pad is provided on the outer surface of the outer support plate. An auxiliary mechanism is provided on the base.

[0008] As a preferred technical solution of this utility model, the spraying mechanism includes a material pump, a connecting hose, and a spray head. The material pump is fixedly installed on the top of the storage tank. The input end of the material pump is connected to the storage tank through a material pumping pipe. One end of the connecting hose is connected to the output end of the material pump, and the other end of the connecting hose is connected to the spray head.

[0009] As a preferred technical solution of this utility model, the driving mechanism includes a motor fixedly installed on the side wall of the mounting base, and the output end of the motor is fixedly connected to the rotating column.

[0010] As a preferred technical solution of this utility model, the auxiliary mechanism includes a column and a guide wheel, the guide wheel is rotatably connected to the top of the column, and the column is fixedly installed on the top of the base.

[0011] As a preferred technical solution of this utility model, a support rod is also fixedly installed on the top of the base, and a bracket is fixedly installed on the top of the support rod.

[0012] As a preferred technical solution of this utility model, a driven connecting rod is hinged on the mounting column, and the other end of the driven connecting rod is hinged to the outer support plate.

[0013] As a preferred technical solution of this utility model, a switch group is provided on the front of the mounting base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] 1. The output end of the second hydraulic cylinder drives the sliding rod to move, which in turn moves the mounting plate. Simultaneously, the mounting plate moves the active connecting rod, which in turn pushes the outer support plate outwards, causing the anti-slip pad on the outer surface of the outer support plate to adhere to the inner wall of the pipe, thus fixing it from the inside. Then, the motor is started, and its output end drives the rotating column to rotate. The rotating column drives the second hydraulic cylinder to rotate, which in turn drives the sliding rod to rotate. The sliding rod drives the mounting plate to rotate, which in turn drives the active connecting rod to rotate. This causes the outer support plate to rotate, thus rotating the pipe. At this point, the worker can hold the spray nozzle and spray the pipe. This achieves fixation from the inside of the pipe while simultaneously rotating it, ensuring a uniform coating of anti-rust paint on the pipe surface, improving corrosion resistance and aesthetics. This solves the problem in existing technologies where workers need to rotate the pipe while brushing to ensure uniform coating, which is inefficient and results in inconsistent coating quality.

The output end of the second hydraulic cylinder 9 is fixedly connected to the slide rod 8. The output end of the second hydraulic cylinder 9 drives the slide rod 8 to move. The other end of the slide rod 8 is fixedly installed with the mounting plate 10. The slide rod 8 drives the mounting plate 10 to move. The mounting plate 10 is hinged with an active connecting rod 11. The moving mounting plate 10 drives the active connecting rod 11. The other end of the active connecting rod 11 is hinged with an outer support plate 12. The active connecting rod 11 then drives the outer support plate 12 to push outward. The outer surface of the outer support plate 12 is provided with an anti-slip pad 13, so that the anti-slip pad 13 on the outer surface of the outer support plate 12 fits against the inner wall of the pipe, thus fixing it from the inside of the pipe without affecting the painting work. An auxiliary mechanism is provided on the base 1.

[0030] The spraying mechanism includes a material pump 14, a connecting hose 15, and a nozzle 16. The material pump 14 is fixedly installed on the top of the storage tank 2. The input end of the material pump 14 is connected to the storage tank 2 through a material extraction pipe. When the material pump 14 is started, it extracts the anti-rust paint from the storage tank 2. One end of the connecting hose 15 is connected to the output end of the material pump 14, and the other end of the connecting hose 15 is connected to the nozzle 16. The paint is delivered to the nozzle 16 through the connecting hose 15 and finally sprayed out from the nozzle 16. The worker holds the nozzle 16 and sprays the paint through the pipe.

[0031] The drive mechanism includes a motor 21 fixedly installed on the side wall of the mounting base 4. The output end of the motor 21 is fixedly connected to the rotating column 5, and the output end of the motor 21 drives the rotating column 5 to rotate.

[0032] The auxiliary mechanism includes a column 17 and a guide wheel 18. The guide wheel 18 is rotatably connected to the top of the column 17. The column 17 is fixedly installed on the top of the base 1. First, the pipe is placed on the guide wheel 18, and then the pipe is pushed.

[0033] A support rod 19 is also fixedly installed on the top of the base 1, and a bracket 20 is fixedly installed on the top of the support rod 19. The bracket 20 is used to place the nozzle 16.

[0034] A driven connecting rod 23 is hinged to the mounting column 7, and the other end of the driven connecting rod 23 is hinged to the outer support plate 12.

[0035] A switch assembly 22 is provided on the front of the mounting base 4. The switch assembly 22 is used to control the motor and the hydraulic cylinder.

[0036] Specifically, when using this metal pipe surface anti-rust spraying device: first, place the pipe on the guide wheel 18, then push the pipe so that the other end of the pipe wraps around the outer support plate 12. Next, start the second hydraulic cylinder 9. The output end of the second hydraulic cylinder 9 drives the slide rod 8 to move, and the slide rod 8 drives the mounting plate 10 to move. At the same time, the mounting plate 10 moves and drives the active connecting rod 11. The active connecting rod 11 then drives the outer support plate 12 to push outward, so that the anti-slip pad 13 on the outer surface of the outer support plate 12 fits against the inner wall of the pipe, thus fixing it from the inside of the pipe without affecting the painting work. Then, start the motor 21. The output end of the motor 21 drives the rotating column 5 to rotate, and the rotating column 5 carries... The second hydraulic cylinder 9 rotates, which in turn drives the slide rod 8 to rotate. The slide rod 8 then drives the mounting plate 10 to rotate, which in turn drives the active connecting rod 11 to rotate. The active connecting rod 11 then drives the outer support plate 12 to rotate, causing the outer support plate 12 to rotate the pipeline. At this time, the worker holds the spray nozzle 16 and starts the material pump 14. The material pump 14 extracts the anti-rust paint from the storage tank 2 and sends it to the spray nozzle 16 through the connecting hose 15, finally spraying it out from the spray nozzle 16. This device can be fixed from the inside of the pipeline, and at the same time, it can drive the pipeline to rotate, which can ensure that the surface of the pipeline can be evenly coated with anti-rust paint, improving the anti-corrosion effect and aesthetics.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
