Description

Technical Field

[0001] This utility model belongs to the field of high-speed rail vehicle technology, specifically, it relates to an environmentally friendly water-based paint circulating spraying and exhaust gas purification device for high-speed rail vehicle maintenance. Background Technology

[0002] Against the backdrop of rapid development in the transportation industry, high-speed rail has become an important mode of passenger transport in my country due to its efficiency and convenience. After long-term operation, the coating on the surface of high-speed rail vehicles will experience wear and aging, requiring regular inspection and repainting.

[0003] Existing spraying equipment for high-speed rail vehicle maintenance often uses a scrubbing tower to extract harmful gases generated after the water-based paint comes into contact with the air, and then purifies the gases in the scrubbing tower. At the same time, existing water-based paints often have problems during the spraying process.

[0004] However, during the spraying process of existing water-based paints, when the water-based paint is sprayed onto the surface of high-speed train vehicles, some of the water-based paint often drips off, resulting in waste as the paint drips onto the ground.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0030] like Figures 1 to 9As shown, an environmentally friendly water-based paint circulating spraying device for high-speed rail vehicle maintenance includes a base plate 1, four support legs 7 on the base plate 1, a top plate 14 above the four support legs 7, sliding brackets 8 between each pair of the four support legs 7, sliding blocks 10 on each of the two sliding brackets 8, and robotic arms 11 on each of the two sliding brackets 8. The two robotic arms 11 are symmetrical to each other and each of the two robotic arms 11 is equipped with a spray head 12. A collection box 16 is provided below each of the two spray heads 12. A screening plate 20 is placed inside each of the two collection boxes 16. A C-shaped fixing plate 21 is provided on the opposite side wall of each of the two collection boxes 16. A flipping scraper 22 is provided below each of the two C-shaped fixing plates 21. A connection port 18 is provided at the bottom of each of the two collection boxes 16, and a liquid inlet pipe 5 is provided on the connection port 18. By moving the collection box 16 and the spray head 12 together, the spray head 12 can always be positioned below the spray head 12. This allows the dripping water-based paint to be collected when the spray head 12 sprays onto the surface of the high-speed train vehicle. The screening plate 20 installed inside the collection box 16 can filter impurities in the water-based paint, ensuring that the filtered water-based paint is relatively clean when it is delivered to the collection box 16. When the screening plate 20 is pulled out, the impurities on the screening plate 20 can be cleaned by the flip scraper 22, thus facilitating the cleaning of impurities on the screening plate 20.

[0031] In a specific embodiment, two mounting bases 2 are provided on the substrate 1, and a water-based paint storage tank 3 is provided above each of the two mounting bases 2. Each water-based paint storage tank 3 is connected to an inlet pipe 5, and each water-based paint storage tank 3 is also provided with an outlet pipe 13. The other end of each outlet pipe 13 is connected to a spray head 12, and a hydraulic pump is provided on each of the two outlet pipes 13. In this configuration, the installation position of the water-based paint storage tank 3 is determined.

[0032] Furthermore, each of the two sliding support plates 9 has an electric push rod 29 on one opposite side wall. The two electric push rods 29 are symmetrical to each other, and their opposite sides are respectively connected to the storage box 16. Each storage box 16 is provided with an L-shaped mounting plate 15, and the other end of the L-shaped mounting plate 15 is respectively set on the sliding block 10. In this configuration, it is ensured that the storage box 16 can always be located below the spray head 12.

[0033] Furthermore, each of the two storage boxes 16 has two symmetrical positioning plates 17 at its bottom, with each positioning plate 17 mounted on the base plate 1. In this configuration, the installation positions of the positioning plates 17 and the storage boxes 16 are determined.

[0034] Furthermore, rectangular slots 24 are provided on one side wall of the inner cavity of the two storage boxes 16. Two symmetrical placement plates 25 are also provided inside the inner cavity of the two storage boxes 16. A conical feeding plate 23 is provided below each pair of placement plates 25. A feeding pipe 19 is provided at the bottom of each of the two conical feeding plates 23, and the other end of the feeding pipe 19 is located at the connection port 18. This configuration defines the installation positions and components within the storage boxes 16.

[0035] Furthermore, bearings 26 are provided on the opposite side walls of the inner cavities of the two C-shaped fixing plates 21. Each bearing 26 is symmetrical to the other two, and a rotating rod 27 is provided between each pair of bearings 26. The opposite side walls of each rotating rod 27 are respectively provided on the flipping scraper 22. A torsion spring 28 is provided between each pair of bearings 26 and on the opposite side wall of the flipping scraper 22. In this configuration, after spraying is completed, the worker can pull the screening plate 20 outward. When the screening plate 20 moves to a certain position, it can squeeze the flipping scraper 22 on the C-shaped fixing plate 21 to flip under the assistance of the bearing 26 and the rotating rod 27 until the screening plate 20 leaves the flipping scraper 22. At this time, the flipping scraper 22 can be reset with the assistance of the torsion spring 28. The reset flipping scraper 22 is located on the screening plate 20. Therefore, when the screening plate 20 is pulled outward, the impurities on the screening plate 20 can be blocked by the flipping scraper 22 until the screening plate 20 is completely removed. At this time, the impurities on the screening plate 20 can be scraped off as much as possible, which facilitates the cleaning of the impurities on the screening plate 20.

[0036] This invention also discloses a waste gas purification device for high-speed rail vehicle maintenance, including a scrubbing tower 4. The scrubbing tower 4 is mounted on a base plate 1. An air inlet pipe 6 is provided on one side wall of the scrubbing tower 4, and the other end of the air inlet pipe 6 is provided on a top plate 14. An air pump is provided on the air inlet pipe 6. The air inlet pipe 6 is used to extract odors generated by the mixing of water-based paint and air during spraying. In this device, by activating the air pump, the gas generated by the mixing of water-based paint and air during the spraying process can be drawn into the air inlet pipe 6 and then enter the scrubbing tower 4 for washing and purification.

[0037] The implementation principle of the environmentally friendly water-based paint circulation spraying and exhaust gas purification device for high-speed rail vehicle maintenance in this embodiment is as follows:

[0038] First, the high-speed train that needs to be repaired is parked between the four support legs 7 (that is, between the two spray heads 12). When the train is parked, the staff controls the operation of the robotic arm 11, which drives the spray head 12 to move, so that the spray head 12 can spray the high-speed train that needs to be repaired (the hydraulic pump applies pressure to the paint in the storage tank, forcing the paint into the spray head and spraying it out).

[0039] When spraying paint on high-speed trains that need maintenance, there may be instances where the water-based paint sprayed on the trains slips off. In such cases, the slipped trains can fall into the storage box 16 (because when the spray head 12 moves back and forth, the storage box 16 can be moved by the L-shaped mounting plate 15 with the assistance of the electric push rod 29 and the sliding support plate 9, thus ensuring that the storage box 16 is always below the side wall of the spray head 12 and the high-speed train that needs maintenance).

[0040] When water-based paint drips into the collection box 16, the screening plate 20 placed inside the collection box 16 can filter out the impurities contained in the water-based paint dripping into the screening plate 20, thus ensuring that the impurities entering the collection box 16 are relatively clean. (When the spraying is finished, the worker can pull the screening plate 20 outward. When the screening plate 20 moves to a certain position, it can squeeze the flipping scraper 22 set on the C-shaped fixing plate 21 to flip under the assistance of the bearing 26 and the rotating rod 27 until the screening plate 20 leaves the flipping scraper 22. At this time, the flipping scraper 22 can be reset with the assistance of the torsion spring 28. At this time, the reset flipping scraper 22 is exactly on the screening plate 20. Therefore, when the screening plate 20 is pulled outward, the impurities on the screening plate 20 can be blocked by the flipping scraper 22 until the screening plate 20 is completely removed. At this time, the impurities on the screening plate 20 can be scraped off as much as possible, thus facilitating the cleaning of the impurities on the screening plate 20.)

[0041] The filtered water-based paint droplets will be able to enter the liquid inlet pipe 5 through the conical feed plate 23 and the feed pipe 19. The liquid is then transported from the liquid inlet pipe 5 to the water-based paint storage tank 3 by starting the liquid pump, thereby ensuring that the dripping water-based paint can be collected for future use.

[0042] At the same time, by starting the air pump, the gas generated after the water-based paint and air mix during the spraying process can be drawn into the air inlet pipe 6 and then enter the washing tower 4 for washing and purification (the exhaust gas enters through the bottom of the tower and comes into full contact with the liquid sprayed from the top of the tower. During the gas-liquid contact process, the pollutants in the exhaust gas dissolve or are adsorbed into the liquid. The purified gas after washing is discharged from the top of the tower, achieving the purification effect).
