[0001] This utility model relates to the field of highway construction equipment technology, and in particular to a highway construction marking device. Background Technology
[0002] As vital arteries of transportation, highways, with their road markings, not only clearly guide traffic flow and provide drivers with accurate driving instructions, but also play an irreplaceable role in ensuring road traffic safety and improving road efficiency. Clear and accurate highway markings can effectively reduce traffic accidents, enhance the safety and smoothness of transportation, and have a positive impact on the stable development of the social economy.
[0003] During highway construction, different road scenarios, such as highways, main roads and branch roads in cities, as well as special road sections such as intersections and curves, have diverse requirements for the width of road markings. The existing highway construction marking devices can only achieve the construction of markings of a single width. Once a scenario requiring markings of different widths is encountered, they cannot be flexibly adjusted. They can only cope with the situation by changing equipment or nozzles, which not only consumes a lot of time and manpower but also greatly reduces construction efficiency. Utility Model Content
[0004] For road marking construction that can only achieve a single width, it is impossible to flexibly adjust when encountering scenarios requiring different widths of markings. The only solution is to replace equipment or nozzles, which is not only time-consuming and labor-intensive but also greatly reduces construction efficiency. This utility model provides a road construction marking device with the advantage of adjustable marking width, solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a highway construction marking device, including a trolley, a storage box and a pressure pump are installed at the upper end of the trolley, the pressure pump is connected to the bottom of the storage box through a pipe, a spray pipe is installed at the output end of the pressure pump, the other end of the spray pipe passes through the upper end of the trolley and is connected to a nozzle, two pipe clamps are installed at the bottom of the trolley, the side of the spray pipe near the nozzle is located inside the pipe clamp, four fixing plates are fixedly installed at the bottom of the trolley, the four fixing plates are respectively located on both sides of the nozzle, two baffles are provided on the inner side of the fixing plates, a connecting shaft is fixedly installed at the upper end of the two baffles, the two sides of the connecting shaft are rotatably connected to the inner side of the fixing plates, one side of the two connecting shafts passes through the fixing plates and is equipped with a transmission gear, the two transmission gears mesh with each other, a motor base is fixedly installed at the bottom of the trolley, a drive motor is installed on the side of the motor base, the output end of the drive motor passes through the motor base and is connected to one of the transmission gears.
[0006] Preferably, a stirring motor is installed at the upper end of the storage box, and the output end of the stirring motor passes through the storage box and is connected to a stirring rod.
[0007] Preferably, the trolley is fixedly mounted on both ends of the side away from the storage box, a brush roller is rotatably connected to the inner side of the mounting frame, a rotary motor is mounted on the side of the mounting frame, and the output end of the rotary motor passes through the mounting frame and is connected to one side of the brush roller.
[0008] By setting up the brush roller, it can directly contact the road surface to remove dust and small particles of debris, thus providing a clean road surface base for road marking construction.
[0009] Preferably, a collection box is installed on the upper part of the side of the trolley near the mounting frame, and a negative pressure fan is installed on the upper part of the collection box. The negative pressure fan is supported and installed inside the collection box.
[0010] By setting up a negative pressure fan, negative pressure is created inside the collection box, which, together with the suction pipe, removes dust and debris from the road surface, maintaining a clean construction environment.
[0011] Preferably, the bottom of the negative pressure fan is connected to the upper end of the collection box via a pipe, and a dust suction pipe is installed at the output end of the negative pressure fan. The other end of the dust suction pipe passes through the trolley and is connected to a dust inlet hopper.
[0012] By setting up the dust inlet hopper, road dust and debris can be effectively collected and guided into the suction pipe, making it easier for the negative pressure fan to suck them into the collection box.

[0014] By setting the discharge pipe valve, it is possible to easily control the discharge of debris from the collection box, clean the collection box in a timely manner, and ensure the continuous normal operation of the device.
[0015] This utility model has the following advantages:
[0016] 1. With two baffles at the bottom of the trolley working together, when the marking width needs to be adjusted, the drive motor is started. The output of the drive motor drives the transmission gear connected to it to rotate. Since the two transmission gears mesh with each other, the two connecting shafts rotate synchronously, causing the baffles to rotate around the connecting shafts. By changing the angle of the baffles, the range of paint sprayed from the nozzle can be effectively blocked and guided, thereby flexibly adjusting the marking width. This avoids the cumbersome operation of changing equipment or nozzles when encountering different marking width requirements with traditional devices, greatly saving time and labor costs and significantly improving construction efficiency.
[0017] 2. The road cleaning structure is formed by the mounting frame, brush roller, and rotary motor installed at the front of the trolley. After the rotary motor is started, the output end drives the brush roller to rotate inside the mounting frame. The rotating brush roller can sweep the construction road surface and remove dust, debris, etc. At the same time, the collection box, negative pressure fan, suction pipe, and dust inlet installed at the top of the trolley form a dust collection system. The negative pressure fan generates suction force, which sucks the dust and debris collected in the dust inlet into the collection box through the suction pipe. This device combines cleaning and dust collection to effectively clean the road surface before construction, improve the adhesion between the markings and the road surface, ensure the firmness and durability of the markings, and extend the service life of the markings.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0025] Please see Figures 1-5A road marking construction device includes a trolley 1. A storage tank 2 and a pressure pump 5 are installed on the upper end of the trolley 1. The pressure pump 5 is connected to the bottom of the storage tank 2 through a pipe. A spray pipe 6 is installed at the output end of the pressure pump 5. The other end of the spray pipe 6 passes through the upper end of the trolley 1 and is connected to a nozzle 8. After the pressure pump 5 is started, the paint at the bottom of the storage tank 2 is extracted and pressurized, and then transported to the nozzle 8 through the spray pipe 6 to achieve stable and continuous paint spraying. Two pipe clamps 7 are installed at the bottom of the trolley 1. The side of the spray pipe 6 near the nozzle 8 is located inside the pipe clamp 7. The pipe clamp 7 is used to fix the part of the spray pipe 6 near the nozzle 8 to prevent the spray pipe 6 from shaking during the spraying process, ensure stable spraying by the nozzle 8, improve the accuracy and uniformity of the marking spraying, and ensure the quality of road marking construction.
[0026] Four fixing plates 9 are fixedly installed at the bottom of the trolley 1, and the four fixing plates 9 are respectively located on both sides of the nozzle 8. Two baffle plates 10 are provided on the inner side of the fixing plates 9. A connecting shaft 11 is fixedly installed on the upper end of the two baffle plates 10. When the connecting shaft 11 rotates, it drives the baffle plates 10 to rotate around the connecting shaft 11. By changing the angle of the baffle plates 10, the range of paint sprayed by the nozzle 8 can be effectively blocked and guided, thereby flexibly adjusting the marking width. This avoids the cumbersome operation of changing equipment or nozzle 8 when encountering different marking width requirements in traditional devices, greatly saving time and labor costs, and significantly improving construction efficiency. The two sides of the connecting shaft 11 rotate respectively. The trolley 1 is movably connected to the inner side of the fixed plate 9. One side of the two connecting shafts 11 passes through the fixed plate 9 and is equipped with a transmission gear 12. The two transmission gears 12 mesh with each other. The bottom of the trolley 1 is fixedly installed with a motor base 13. The side of the motor base 13 is equipped with a drive motor 14. The output end of the drive motor 14 passes through the motor base 13 and is connected to one of the transmission gears 12. With the cooperation of two baffles 10 set at the bottom of the trolley 1, when the width of the marking line needs to be adjusted, the drive motor 14 is started. The output end of the drive motor 14 drives the transmission gear 12 connected to it to rotate. Since the two transmission gears 12 mesh with each other, the two connecting shafts 11 rotate synchronously.
[0027] Please see Figures 1-3 A stirring motor 3 is installed at the upper end of the storage box 2. The output end of the stirring motor 3 passes through the storage box 2 and is connected to the stirring rod 4. The two ends of the trolley 1 away from the storage box 2 are fixedly installed with mounting frames 15. The inner side of the mounting frame 15 is rotatably connected to the brush roller 16. The side of the mounting frame 15 is equipped with a rotary motor 17. The output end of the rotary motor 17 passes through the mounting frame 15 and is connected to one side of the brush roller 16. The mounting frame 15, the brush roller 16 and the rotary motor 17 installed at the front end of the trolley 1 together form a road cleaning structure. After the rotary motor 17 is started, the output end drives the brush roller 16 to rotate inside the mounting frame 15. The rotating brush roller 16 can sweep the construction road surface and remove dust, debris and other objects from the road surface.
[0028] A collection box 18 is installed on the upper part of the side of the trolley 1 near the mounting frame 15. A negative pressure fan 19 is installed on the upper part of the collection box 18. The negative pressure fan 19 is supported on the upper part of the collection box 18. The bottom of the negative pressure fan 19 is connected to the inside of the collection box 18 through a pipe. A suction pipe 20 is installed at the output end of the negative pressure fan 19. The other end of the suction pipe 20 passes through the trolley 1 and is connected to a dust inlet 21. The dust inlet 21 is located at the bottom of the trolley 1. The collection box 18, negative pressure fan 19, suction pipe 20 and dust inlet 21 installed on the upper part of the trolley 1 constitute a dust collection system. When the negative pressure fan 19 is started, it generates suction. The dust and debris collected in the dust hopper 21 are sucked into the collection box 18 through the suction pipe 20. This device combines cleaning and dust collection, effectively cleaning the road surface before construction, improving the adhesion between the markings and the road surface, ensuring the firmness and durability of the markings, and extending the service life of the markings. The bottom of the collection box 18 is fixedly installed with a discharge pipe 22. The inside of the discharge pipe 22 is equipped with a valve. When a lot of debris accumulates in the collection box 18, the valve is opened, and the debris is discharged through the discharge pipe 22 under the action of gravity, which greatly improves the convenience of cleaning debris and effectively reduces the workload of construction personnel.
[0029] Working principle: In actual use, first turn on the stirring motor 3 to drive the stirring rod 4 to rotate in the storage tank 2 to continuously stir the paint in the tank. Then, start the pressure pump 5 to extract the paint at the bottom of the storage tank 2 through the pipeline and pressurize and deliver it to the spray pipe 6, and then spray it out from the nozzle 8. At this time, if it is necessary to adjust the width of the marking line, turn on the drive motor 14. The output shaft of the drive motor 14 drives the transmission gear 12 connected to it to rotate. Since the two transmission gears 12 mesh with each other, they drive the other transmission gear 12 to rotate synchronously, thereby causing the two connecting shafts 11 to rotate synchronously. The connecting shaft 11 drives the baffle plate 10 to rotate around it. By controlling the rotation angle of the baffle plate 10, the range of paint sprayed by the nozzle 8 can be blocked and guided, so as to achieve flexible adjustment of the width of the marking line.
[0030] During the movement of the trolley 1, the rotary motor 17 is turned on to drive the brush roller 16 to rotate at high speed inside the mounting frame 15. The brush roller 16 continuously sweeps the road surface, cleaning up dust, debris, and other contaminants. At the same time, the negative pressure fan 19 is started, generating suction. The suction pipe 20 draws the dust and debris collected in the dust inlet 21 at the bottom of the trolley 1 into the collection box 18, allowing the markings to adhere better to the road surface and improving the firmness and durability of the markings. When a certain amount of debris accumulates in the collection box 18, the valve on the discharge pipe 22 at the bottom of the collection box 18 can be opened to discharge the debris from the collection box 18, so that debris generated during subsequent road cleaning can be collected.
