Description

Highway pavement marking equipment with cleaning function Technical Field

[0001] This invention relates to the field of highway construction technology, specifically to highway pavement marking equipment with cleaning function. Background Technology

[0002] Road markings are a crucial visual guidance system applied to road surfaces. Their core functions include efficiently guiding traffic flow, significantly improving road capacity, enhancing driving safety, and effectively regulating the behavior of drivers and pedestrians. These markings are typically painted with highly visible and abrasion-resistant colored paint. Through carefully designed and diverse shapes, patterns, and color coding, they convey key information to road users, such as clear right-of-way divisions, driving direction guidance, warnings of dangerous areas, and behavioral norms. As the primary tool for applying road markings, road marking spraying equipment is the fundamental equipment for achieving these traffic management goals. Clear, durable, and standardized markings play an indispensable role in maintaining traffic order and preventing accidents.

[0003] Thoroughly cleaning the target road surface before applying road markings is the first step to ensure the quality and durability of the markings. If dust, mud, oil, water stains, or residue from old markings are not removed from the area to be painted, the adhesion between the new paint and the road surface will be severely weakened, leading to premature peeling, fading, or damage to the markings, significantly shortening their lifespan. Furthermore, hard debris such as pebbles scattered on the road surface not only affects the smoothness of the paint application but may also be caught in the equipment or impact the nozzle during the painting process, interfering with normal operations. Another key challenge lies in the dynamic process of painting: the speed of the construction vehicle is not constant during operation, while the paint output of traditional equipment is usually set to a fixed value. This mismatch between speed and flow rate leads to uneven thickness of the marking coating. When vehicle speed increases, the amount of paint received per unit area decreases, resulting in excessively thin markings. These markings lack reflectivity and clarity, making them difficult for drivers to identify, especially at night or in inclement weather, easily leading to misjudgments and even traffic accidents. Conversely, when vehicle speed decreases, paint accumulates, causing excessively thick markings. This not only wastes material but also creates significant localized bumps, affecting road surface smoothness, reducing driving comfort, and potentially accelerating wear under vehicle pressure, while also detracting from the road's aesthetics. Therefore, effectively addressing the cleaning issue and achieving coordinated control of spray flow and vehicle speed are crucial for ensuring the quality of road markings.

[0004] Therefore, we now offer road marking equipment with cleaning functions, which can eliminate the drawbacks of existing devices. Summary of the Invention

When the transmission rod 29 rotates, it drives the rotating rod 23 to rotate through the meshing of the second bevel gear and the first bevel gear. Under the action of centrifugal force, the sliding block 24 slides on the rotating rod 23. The sliding plate drives the first valve core 21 to slide through the fixed rod, thereby adjusting the discharge amount of the fixed material pipe 12. When the rotation speed of the roller 31 increases, the moving distance of the first valve core 21 increases. When the roller 31 stops, under the action of the fifth return spring, the sliding block 24 slides to the initial position, and the first valve core 21 closes the end of the first valve core 21.

A first synchronous gear is fixedly provided, and a second synchronous gear is fixedly provided on the transmission rod 29. The first and second synchronous gears are connected by a synchronous belt 49. In use, when the nozzle 11 is working, the transmission rod 29 drives the reducer 53 to rotate through the meshing of the second and fifth bevel gears. The output end of the reducer 53 rotates slowly, driving the push rod 52 to rotate. When one end of the push rod 52 is in close contact with the bottom end of the guide block 51, the push rod 52 pushes the first friction plate 44 to move through the guide block 51 and the rotating plate 50. When the bottom ends of the first friction plate 44 and the second friction plate 45 are in close contact, the transmission rod 29 drives the third gear 48 to rotate through the synchronous belt 49. The third gear 48 meshes with the second gear 47, driving the first friction plate 44 to rotate. The first friction plate 44 drives the first gear 43 to rotate via the second friction plate 45. The first gear 43 meshes with the first rack 42, causing the second valve core 41 to move. The second valve core 41 then drives the second rack 54 to move. Since the one-way wheel 55 rotates in one direction, the first fixed shaft does not rotate. At the same time, the second valve core 41 seals one end of the fixed material tube 12, and the nozzle 11 stops working. Subsequently, when the push rod 52 disengages from the guide block 51, the first friction plate 44 separates from the second friction plate 45. Under the action of the torsion spring, the second valve core 41 moves back to its initial position. Simultaneously, the one-way wheel 55 drives the first fixed shaft to rotate. The first fixed shaft drives the third rack 56 to slide via the fourth gear. The output end of the third rack 56 retracts. Under the action of the third rack 56...This can slow down the movement speed of the second valve core 41.

[0042] The above embodiments disclose a road surface marking device with a cleaning function. The user pulls the limiting frame 38, causing one end of the limiting frame 38 to disengage from the limiting groove. Then, the user rotates the mounting rod 36, causing the mounting rod 36 to drive the sliding plate 33 and the fixed plate 35 to rotate. The fixed plate 35 disengages from the bottom end of the extension plate. Subsequently, the fixed pipe 30 and the mounting plate 67 descend, the roller 31 is in close contact with the ground, and the nozzle 11 is in the working position. When the nozzle 11 is working, the pump body 14 draws raw material from the storage tank 15, and the pump body 14 transports the raw material to the fixed pipe 12 through the conveying pipe 13. Simultaneously, the air compressor 18 delivers... High-pressure gas is supplied to the fixed material pipe 12 through the first air pipe 19 at the outlet, so that the nozzle 11 sprays out the raw material for marking work. When the roller 31 passes over the rough road surface, the nozzle 11 moves with the roller 31. When the roller 31 rotates, the roller 31 drives the transmission rod 29 to rotate through the engagement of the fourth bevel gear and the third bevel gear. The transmission rod 29 drives the rotating rod 23 to rotate through the engagement of the second bevel gear and the first bevel gear. Under the action of centrifugal force, the sliding block 24 slides on the rotating rod 23. The sliding plate drives the first valve core 21 to slide through the fixed rod, so as to adjust the discharge amount of the fixed material pipe 12.

[0043] The transmission rod 29 drives the reducer 53 to rotate through the meshing of the second bevel gear and the fifth bevel gear. The output end of the reducer 53 rotates slowly, and the output end of the reducer 53 drives the push rod 52 to rotate. When one end of the push rod 52 is in close contact with the bottom end of the guide block 51, the push rod 52 pushes the first friction plate 44 to move through the guide block 51 and the rotating plate 50. When the bottom end of the first friction plate 44 is in close contact with the bottom end of the second friction plate 45, the transmission rod 29 drives the third gear 48 to rotate through the synchronous belt 49. The third gear 48 meshes with the second gear 47 to drive the first friction plate 44 to rotate. The first friction plate 44 drives the first gear 43 to rotate through the second friction plate 45. The first gear 43 meshes with the first rack 42 to drive the second valve core 41 to move. The second valve core 41 drives the second rack 54 to move. Since the one-way wheel 55 rotates in one direction, the first fixed shaft does not rotate. At the same time, the second valve core 41 seals one end of the fixed material tube 12, and the nozzle 11 no longer works.

[0044] When marking the road, the output of the motor 62 drives the cleaning brush roller 60 to rotate, and at the same time, the output of the air compressor 18 delivers high-pressure gas into the cleaning brush roller 60 through the second air pipe 65. After the exhaust hole on the cleaning brush roller 60 rotates to the exhaust gap, the gas is discharged, thereby cleaning the dust on the road surface. At the same time, the bristles on the cleaning brush roller 60 clean the stones.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
