Description

Technical Field

[0001] The utility model relates to the technical field of road markings, in particular to a road marking removing device. Background Art

[0002] For the driving safety of vehicles and pedestrians, various road markings are usually used as guide marks. Road markings are usually coated with hot-melt raw materials, such as petroleum resin. However, as vehicles and pedestrians wear the road markings, the road markings break, affecting pedestrians' recognition of the markings. Therefore, when the road markings are severely worn, they often need to be redrawn. In order to avoid the impact of the original markings on vehicles and pedestrians, the original markings need to be removed.

[0003] Most of the existing road marking removal devices achieve the purpose of destroying the marking traces and removing the road markings by grinding the markings. However, the current cleaning devices are often accompanied by the generation of dust particles in the process of cleaning the road markings, which pollutes the air. Although the dust particles generated in the cleaning process can be collected by using a road dust reduction device, the road still needs to be cleaned after the dust is collected, which results in many subsequent cleaning steps for the road marking removal and a long overall cleaning time for the road markings. For this reason, we propose a road marking removal device that can save cleaning time. Utility Model Content

[0023] The top of the mobile support structure is detachably connected to a water tank 15 through a connecting groove 3, and a water volume window is connected to the surface of the water tank 15. The top of the water tank 15 is connected to a steering component through a lifting structure, and the lifting structure can lift the water in the water tank 15 in a vertical direction. The lifting structure includes a lifting pump 14 connected to the water tank 15, and a bellows 13 is connected to the side of the lifting pump 14. A bearing 131 is installed at the connection between the lower end of the bellows 13 and the steering component. The bellows 13 can be extended or shortened to adjust its own length according to the height of the positioning plate 5. The steering component includes a driving motor 8, and the output end of the driving motor 8 is connected to a driving bevel gear 81. The surface of the driving bevel gear 81 is meshed with a driven bevel gear 9. The interior of the driven bevel gear 9 is provided with a water flow channel connected to a high-pressure water outlet channel 11. A connecting pipe that movably penetrates the positioning plate 5 is connected between the water jet sanding disc 10 and the driven bevel gear 9. A rolling bearing is movably connected to the connection between the connecting pipe and the positioning plate 5, so that the water jet sanding disc 10 can perform circular motion.

[0024] The lower end of the steering component is connected to a water jet sanding disc 10. After the steering component is started, the water jet sanding disc 10 can be pulled to rotate in the horizontal direction. The bottom of the water jet sanding disc 10 is connected through a plurality of high-pressure water outlet channels 11 arranged in a circular array. The high-pressure water outlet channel 11 ejects high-pressure water flow, and the cutting force generated by the high-pressure water flow can cut and destroy the road markings, so that the markings are separated from the road surface. A sanding ring 12 is coaxially welded to the bottom of the water jet sanding disc 10. The bottom surface of the sanding ring 12 is a frosted surface, which can grind and crush the markings. The grinding effect of the sanding ring 12 on the markings is combined with the cutting effect of the high-pressure water outlet channel 11, thereby accelerating the clearing speed of the road markings and improving the clearing efficiency of the markings. The top of the mobile support structure is connected to the positioning plate 5 through a lifting component. The lifting component includes a stepping motor 6 fixed on the top of the support plate 1 and a limiting edge 4 welded to the inner wall of the connecting groove 3.

[0025] A recovery component is installed at one end of the mobile support structure. The recovery component can recover the water and impurities generated after the road markings are cleaned with high-pressure water flow, reduce pollution to the road, and facilitate the re-marking of the road markings. The recovery component includes a recovery water storage chamber 16, the bottom of the recovery water storage chamber 16 is connected to a sediment pump 17, and the bottom of the sediment pump 17 is connected to a sediment pipe 18.

[0026] Preferably, Figure 2 and Figure 3 As shown, the output end of the stepper motor 6 is connected to the driving shaft 7, and the driving shaft 7 is threadedly connected to the inner wall of the positioning plate 5. When the stepper motor 6 is started, the output end of the stepper motor 6 cooperates with the limiting edge 4 to pull the positioning plate 5 to move in the vertical direction to adjust the height through the driving shaft 7.

The absorption hole 20 can absorb and intercept the marking cleaning water flow to avoid polluting the road.

[0028] Preferably, Figure 5 As shown, the absorption holes 20 are arranged linearly with equal spacing, which can increase the sewage absorption speed.

[0029] Working principle: When in use, the input end of the road marking removal device is electrically connected to an external power supply, and the lifting pump 14 is started. The lifting pump 14 pressurizes the water in the water tank 15 and sprays it to the water jet sanding disc 10. Through the high-pressure water outlet channel 11 at the bottom of the water jet sanding disc 10, multiple high-pressure water jets are sprayed onto the road markings to cut and break the road markings. At the same time, the water flow can wash away the cut road marking fragments, clean the road after the road markings are removed, and reduce the dust raised in the process of removing the road markings, which is beneficial to the cleaning and dust reduction of the road. When the water jet from the high-pressure water outlet channel 11 cannot completely remove the road markings, the road markings will be cleaned. Full cleaning, by starting the stepper motor 6, the height of the positioning plate 5 can be adjusted by the driving shaft 7 at the output end of the stepper motor 6, and the distance between the frosting circle 12 and the road marking can be adjusted, so that the frosting circle 12 can grind the road marking, and the cleaning intensity of the marking can be enhanced with the high-pressure water column, saving the marking cleaning time. The water for cleaning the marking is intercepted by setting a U-shaped intercepting rod 19. The water after cleaning the marking can absorb water and impurities through the absorption hole 20. The water for cleaning the marking is recovered by the silt pump 17 and the silt pipe 18, and the recovered water can be lifted to the recovery water storage chamber 16 for storage.
