Description

Technical Field

[0001] This utility model relates to the field of traffic marking vehicle technology, and in particular to a traffic marking vehicle nozzle anti-clogging and diversion device with self-cleaning function. Background Technology

[0002] Traffic marking vehicles are specialized engineering vehicles used for the application and maintenance of road markings. They are typically equipped with core components such as a hot melt autoclave, a spraying system, and a guide device. Their main function is to efficiently draw road markings such as lane lines, zebra crossings, and turn arrows through automated operation. They also have the ability to remove old lines and spray reflective glass beads. These vehicles are widely used in urban roads, highways, parking lots, and other scenarios. Their operational accuracy can reach the millimeter level, improving efficiency by 5-10 times compared to manual marking. They can also ensure uniform marking thickness and meet nighttime reflectivity standards. Modern high-end models also integrate GPS positioning and intelligent control systems, which can automatically generate standardized marking patterns based on digital maps, significantly improving road traffic safety and the modernization of municipal construction.

[0003] Traditional traffic marking vehicle nozzles are prone to clogging and lack self-cleaning capabilities, requiring frequent shutdowns for manual cleaning. This interrupts the work process and delays the marking progress, potentially exacerbating traffic congestion, especially on roads with high traffic volume. Clogging can also lead to uneven application of the marking paint, broken lines, or abnormal distribution of reflective glass beads, affecting the clarity of the markings and their nighttime reflectivity, thus increasing the risk of traffic accidents. Repeatedly disassembling and cleaning the nozzles accelerates component wear and shortens the equipment's lifespan. At the same time, the accumulated costs of specialized cleaning fluids and manual maintenance drive up operating costs.

[0004] Therefore, in response to the problems of traditional traffic marking vehicle nozzles being prone to clogging and lacking self-cleaning functions, which lead to reduced construction efficiency, increased safety hazards, and shortened equipment lifespan, a traffic marking vehicle nozzle anti-clogging and diversion device with self-cleaning function can be designed to solve these problems.

One transmission component is connected to a cleaning component, and the other transmission component is connected to a scribing component. When a blockage is detected and cleaning is required, the first motor 2 outputs torque to the drive shaft 3, causing the drive shaft 3 to drive the drive gear 4 to rotate. The drive gear 4 drives the driven gear 5 meshing on one side to rotate. The driven gear 5 drives the cam connecting plate 7 to rotate on the fixed shaft 6, causing the connecting rod 8 on the arc-shaped slide groove 701 to slide. The two connecting rods 8 move in opposite directions, one rising and the other falling, causing the moving plate 9 to slide. This allows for non-stop replacement. The transmission components are used to exchange the working devices on the two moving plates 9. The cleaning component is used for cleaning, and the scribing component is used to continue scribing.

[0024] Please see Figures 1-4In this embodiment, a fixed sliding plate 10 is fixedly connected to the mounting plate 1. Two T-shaped sliding blocks 901 are provided behind the movable plate 9. The T-shaped sliding blocks 901 are slidably connected to the fixed sliding plate 10. When the movable plate 9 moves, the T-shaped sliding blocks 901 slide on the fixed sliding plate 10 to limit the movement. A nozzle body 11 is fixedly connected to the front of the movable plate 9. A quick connector 12 is fixedly connected to the top of the nozzle body 11. A flow sensor 13 is fixedly connected to the bottom of the nozzle body 11. The flow sensor 13 is electrically connected to the first motor 2. The nozzle body 11 is used to realize the traffic marking function. The quick connector 12 is used for quick function switching. The flow sensor 13 is used to detect the flow of the nozzle body 11 to determine whether there is a blockage. In case of blockage, and upon detecting an abnormality, a control signal is triggered to notify the first motor 2 to start. The flow sensor 13 in this device is a DN40 sensor. The transmission assembly includes a second motor 1401, a slide rail 1402, and a threaded rod 1403. The second motor 1401 is fixedly connected to the mounting plate 1. The output end of the second motor 1401 is fixedly connected to the threaded rod 1403. The second motor 1401 is used to drive the threaded rod 1403 to rotate. The threaded rod 1403 is rotatably connected to the slide rail 1402, which is fixedly connected to the mounting plate 1. The second motor 1401 outputs torque to the threaded rod 1403, causing the threaded rod 1403 to rotate on the slide rail 1402, thereby realizing the conveying of different components.

[0025] Please see Figures 4-5In this embodiment, the cleaning assembly includes a slider 1501, a first telescopic rod 1502, a micro motor 1503, and a high-pressure cleaning head 1504. The slider 1501 is threadedly connected to the threaded rod 1403. The lower end of the slider 1501 is fixedly connected to the first telescopic rod 1502. The other end of the first telescopic rod 1502 is fixedly connected to the micro motor 1503. The output end of the micro motor 1503 is fixedly connected to the high-pressure cleaning head 1504. The micro motor 1503 drives the high-pressure cleaning head 1504 to rotate. When the threaded rod 1403 rotates, it drives the slider 1501 to move linearly to the nozzle body. Above 11, the first telescopic rod 1502 extends, driving the micro motor 1503 and the high-pressure cleaning head 1504 to move towards the nozzle body 11. Simultaneously, the micro motor 1503 outputs torque to the high-pressure cleaning head 1504, causing it to rotate and clean the nozzle body 11. A water tank 16 is fixedly connected to the mounting plate 1, and a first booster pump 17 is fixedly connected to the water tank 16. A water supply pipe 18 is fixedly connected to the output end of the first booster pump 17. The first booster pump 17 pressurizes water and delivers it to the water supply pipe 18. The other end of the water supply pipe 18 is fixedly connected to the slider 1501. 17 generates negative pressure, which transports water from water tank 16 to slider 1501 through water pipe 18, and finally sprays it out through high-pressure cleaning head 1504. The marking assembly includes a second telescopic rod 1901, a connecting block 1902, a third telescopic rod 1903, a second booster pump 1904, a sealing joint 1905, and a feeding pipe 1906. The second telescopic rod 1901 is threaded onto the threaded rod 1403. The other end of the second telescopic rod 1901 is fixedly connected to the connecting block 1902. The lower part of the connecting block 1902 is fixedly connected to the third telescopic rod 1903. The other end of the third telescopic rod 1903 is fixed to the second booster pump 1904. The output end of the second booster pump 1904 and the sealing joint 1905 are fixedly connected. The feed pipe 1906 is fixedly connected above the connecting block 1902. The threaded rod 1403 rotates, driving the second telescopic rod 1901 to move linearly towards the nozzle body 11. Both the second telescopic rod 1901 and the third telescopic rod 1903 extend until the sealing joint 1905 and the feed pipe 1906 are tightly connected to the nozzle body 11. Then, the marking material is transported to the second booster pump 1904 through the feed pipe 1906. The second booster pump 1904 generates negative pressure, causing the marking material to be sprayed out from the nozzle body 11, completing the marking work.

[0026] During operation, the second motor 1401 outputs torque to the threaded rod 1403, causing the threaded rod 1403 to rotate on the slide rail 1402. This drives the second telescopic rod 1901 to move linearly towards the nozzle body 11. Then, both the second telescopic rod 1901 and the third telescopic rod 1903 extend until the sealing joint 1905 and the feeding pipe 1906 are tightly connected to the nozzle body 11. The marking material is then transported to the second booster pump 1904 through the feeding pipe 1906. The second booster pump 1904 generates negative pressure, causing the marking material to be sprayed out of the nozzle body 11, completing the marking work. Simultaneously, the flow sensor 13 detects the flow rate of the nozzle body 11 to determine if there is any blockage. If an abnormality is detected, a control signal is triggered to notify the first motor 2 to start. The first motor 2 outputs torque to the drive shaft 3, causing the drive shaft 3 to drive the drive gear 4 to rotate. The drive gear 4 drives the gear meshing on one side. The driven gear 5 rotates, driving the cam connecting plate 7 to rotate on the fixed rotating shaft 6, causing the connecting rod 8 on the arc-shaped slide groove 701 to slide. The two connecting rods 8 move in opposite directions, one rising and the other falling, driving the nozzle body 11 on the moving plate 9 to slide, allowing for non-stop replacement. Then, the threaded rod 1403 rotates, driving the slider 1501 to move linearly, moving it above the nozzle body 11 that needs cleaning. Then, the first telescopic rod 1502 extends, driving the micro motor 1503 and the high-pressure cleaning head 1504 to move towards the nozzle body 11. At the same time, the first booster pump 17 generates negative pressure, transporting water from the water tank 16 to the slider 1501 through the water pipe 18. Then, the micro motor 1503 outputs torque to the high-pressure cleaning head 1504, causing the high-pressure cleaning head 1504 to rotate, allowing water to flow out through the high-pressure cleaning head 1504 to clean the nozzle body 11.

[0027] Through the above steps, the combination of the quick-switching structure and self-cleaning components of the two nozzle bodies 11 significantly reduces downtime for replacement, improves construction efficiency, and automatically cleans residual paint from the nozzles, preventing clogging, extending equipment lifespan, preventing paint drying or mixing contamination, ensuring that the color and thickness of each line marking meets standards, improving the durability of the markings, guaranteeing construction quality, ensuring the accuracy of the markings, and reducing the risk of traffic accidents. This solves the problems of traditional traffic marking vehicle nozzles being prone to clogging and lacking self-cleaning functions, leading to reduced construction efficiency, increased safety hazards, and shortened equipment lifespan.
