Description

Technical Field

[0001] This utility model relates to the field of road marking technology, and in particular to a road marking vehicle. Background Technology

[0002] Road marking vehicles (also called road marking trucks, hot-melt marking machines, etc.) use lines, arrows, text, vertical markings, raised pavement markers, and delineators on road surfaces to convey traffic information such as guidance, restrictions, and warnings to road users. Their function is to regulate and guide traffic. They can be used in conjunction with signs or independently. They are specialized vehicles or equipment used for marking roads, urban roads, parking lots, airport runways, and other surfaces.

[0003] Existing technologies, such as a road marking cart (authorization number CN222878485U), sweep the stones on the road surface to one side, making the road surface cleaner and smoother, which is beneficial for subsequent marking operations. This improves the road surface cleaning effect, facilitates subsequent road maintenance and marking work, and ensures the smoothness and safety of the road surface.

[0004] Currently, there is a lack of road marking vehicles that can easily sweep away gravel, leaves, and other debris from the marked areas and collect them.

[0005] Therefore, a road marking vehicle is proposed to address the aforementioned problems. Summary of the Invention

[0006] This utility model addresses the shortcomings of existing technologies by developing a road marking vehicle. This utility model uses a special marking nozzle set on the side of the vehicle to facilitate marking, while the sweeping brush cleans up gravel, leaves and other debris under the dust collection hood for easy collection by the vacuum cleaner.

[0007] The technical solution to the problem solved by this utility model is as follows: This utility model provides a road marking vehicle, including: a vehicle assembly and a marking assembly, wherein the marking assembly is mounted on the vehicle assembly; the vehicle assembly includes a vehicle, and a nozzle bracket is mounted on one side of the vehicle; the marking assembly includes a liquid storage tank, a liquid pump, and a dedicated marking nozzle, wherein the liquid storage tank and the liquid pump are mounted in the middle and rear part of the vehicle chassis, and the dedicated marking nozzle is fixedly connected to a liquid pipe connector, which is connected to the nozzle bracket; the liquid storage tank and the liquid pipe connector are respectively connected to the liquid pump through pipelines. The liquid pump in the marking assembly is driven by a power system, which delivers the marking liquid in the liquid storage tank to the dedicated marking nozzle through pipelines. The dedicated marking nozzle evenly sprays the marking liquid onto the road according to a preset pattern and line width, forming clear and durable road markings.

[0008] As an optimization, a cleaning assembly is also included. This assembly comprises an L-arm, with a support plate mounted on the front of the vehicle. The L-arm is rotatably connected to the support plate. This rotatable design allows the cleaning assembly to be retracted when not in use, facilitating the movement and storage of the road marking vehicle. The L-arm is connected to a vertical plate with a straight groove. A guide rod is connected to the vertical plate, passing through a T-bar. The vertical rod of the T-bar is housed within a vertical tube, which is connected to a power rod. This power rod is also housed within the straight groove, and the vertical tube is connected to a sweeping brush. The sweeping brush is used to clean the road before or after road marking, ensuring the marked area is clean and flat. The power rod moves along the straight groove; when it is in the lower groove, it sweeps away impurities; when it is in the upper groove, it moves away from the ground in the opposite direction to avoid moving impurities.

[0009] As an optimization, the bristle structure of the cleaning brush is a hybrid of nylon and steel wire.

[0010] As an optimization, the cleaning assembly also includes a vacuum cleaner and a dust cover. The vacuum cleaner is mounted on the front of the vehicle near the support plate. The dust cover is fixedly connected to a dust collection connector, which is connected to the L-arm. This allows the dust cover to flexibly follow the movement of the L-arm, ensuring that the dust cover always maintains a tight fit with the ground and effectively absorbs impurities. The vacuum cleaner and the dust collection connector are connected by a corrugated pipe. The flexibility of the corrugated pipe ensures that the connection between the vacuum cleaner and the dust collection connector is not affected by the movement of the L-arm, avoiding air leakage and insufficient suction during vacuuming.

[0011] As an optimization, the design of the dust hood takes into account the fit with the ground and the dust collection efficiency, ensuring that impurities can be collected to the maximum extent during the dust collection process, further improving the cleanliness of the road marking area.

[0012] As an optimization, the vertical plate is connected to a motor, the motor's output shaft passes through the vertical plate, and the motor's output shaft is connected to a sliding groove, within which the drive rod is positioned. This design, with the drive rod and sliding groove working together, allows the drive rod to slide smoothly within the groove and ensures that the sweeping brush moves along a predetermined trajectory during operation, resulting in more efficient cleaning. The motor's drive provides a stable power source for the drive rod, ensuring continuous operation of the sweeping brush.

[0013] As an optimization, the support plate is provided with two positioning holes, and the L-arm is connected by threaded bolts that match the positioning holes. This makes the connection between the L-arm and the support plate more secure. By screwing the bolts into the positioning holes, the position of the L-arm can be adjusted to achieve cleaning or retraction.

[0014] As an optimization, the liquid storage tank is threaded onto an end cap, facilitating the addition of liquid to the tank.

[0015] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0016] (1) By adopting a dust suction hood, this utility model ensures the maximum dust suction effect, reduces the residue of impurities in the marked area, and thus improves the cleaning efficiency of the road marking vehicle.

[0017] (2) The present invention uses the combination design of the power rod, the sliding groove and the straight groove to enable the sweeping brush to move along the predetermined trajectory, thereby improving the sweeping effect.

[0018] (3) The L-arm of this utility model is adjustable, which makes it convenient to sweep and retract. The position adjustment achieved by bolts improves the stability of the equipment. Attached Figure Description

[0030] like Figures 1 to 5As shown in Embodiment 1: A road marking vehicle includes a vehicle assembly 1 and a marking assembly 2, wherein the marking assembly 2 is mounted on the vehicle assembly 1. The vehicle assembly 1 includes a vehicle 11, and a nozzle bracket 13 is mounted on one side of the vehicle 11. The marking assembly 2 includes a liquid storage tank 21, a liquid pump 23, and a dedicated marking nozzle 24. The liquid storage tank 21 and the liquid pump 23 are mounted in the middle and rear part of the chassis of the vehicle 11. The dedicated marking nozzle 24 is fixedly connected to a liquid pipe connector 25, which is connected to the nozzle bracket 13. The liquid storage tank 21 and the liquid pipe connector 25 are respectively connected to the liquid pump 23 through pipelines. The liquid pump 23 in the marking assembly 2 is driven by a power system and delivers the marking liquid in the liquid storage tank 21 to the dedicated marking nozzle 24 through pipelines. The dedicated marking nozzle 24 sprays the marking liquid evenly on the road according to a preset pattern and line width, forming clear and durable road markings.

[0031] Vehicle component 1 is also equipped with a power system to power the entire road marking vehicle. The power system may include an engine, electric motor, or other suitable power source to ensure smooth and efficient vehicle operation. Furthermore, vehicle component 1 may also include a control system for controlling the vehicle's speed, direction, and the operating status of the marking component 2, thereby improving the accuracy and efficiency of the marking operation. This is prior art, and its structure and principles are well known to those skilled in the art, and will not be described in detail here.

[0032] The liquid storage tank 21 is threadedly connected to the end cap 22, facilitating the addition of liquid to the liquid storage tank 21.

[0033] The workflow of this embodiment is as follows:

[0034] Add an appropriate amount of the marked liquid to the storage tank 21.

[0035] Control the vehicle 11 to move at a constant speed, turn on the liquid pump 23, so that the marking liquid is sprayed from the marking nozzle 24 onto the road surface to achieve marking.

[0036] Example 2: This example further elaborates on Example 1 and includes a cleaning component 3. The cleaning component 3 includes an L-arm 36, and a support plate 12 is installed at the front end of the vehicle 11. The L-arm 36 is rotatably connected to the support plate 12. The rotatable connection design of the L-arm 36 allows the cleaning component 3 to be retracted when not in use, facilitating the movement and storage of the road marking vehicle. The L-arm 36 is connected to a vertical plate 32, which has a straight groove 34. The vertical plate 32 is connected to a guide rod 37, which passes through a T-bar 310. The vertical rod of the T-bar 310 is located inside a vertical tube 311, which is connected to a power rod 314. The power rod 314 is located inside the straight groove 34, and the vertical tube 311 is connected to a sweeping brush 312. The sweeping brush 312 is used to clean the road before or after road marking to ensure the marked area is clean and flat. The power rod 314 moves along the straight groove 34. When it is in the lower straight groove, it cleans up impurities. When it is in the upper straight groove, it moves away from the ground in the opposite direction to avoid moving impurities.

[0037] The bristle structure of the cleaning brush 312 is a hybrid of nylon and steel wire.

[0038] This hybrid design combines the flexibility of nylon with the durability of steel wire, allowing the 312 sweeper brush to effectively remove stains and impurities while maintaining bristle durability and resistance to deformation. The soft nylon bristles conform to the road surface, cleaning fine dirt, while the stiffer steel wire bristles tackle stubborn impurities and stains, ensuring thorough cleaning of marked areas. Furthermore, the hybrid design enhances the overall strength of the 312 sweeper brush, making it more durable, reducing replacement frequency, and lowering maintenance costs.

[0039] The vertical plate 32 is connected to the motor 38, and the output shaft of the motor 38 passes through the vertical plate 32. The output shaft of the motor 38 is connected to the slide groove 313, and the power rod 314 is disposed within the slide groove 313. The cooperative design of the power rod 314 and the slide groove 313 allows the power rod 314 to slide smoothly within the slide groove 313, and also ensures that the sweeping brush 312 can move along a predetermined trajectory during operation, thereby achieving a more efficient sweeping effect. The drive of the motor 38 provides a stable power source for the power rod 314, ensuring the continuous operation of the sweeping brush 312.

[0040] The support plate 12 is provided with two positioning holes 14, and the L-arm 36 is threadedly connected to bolts 39, with the bolts 39 matching the positioning holes 14. This makes the connection between the L-arm 36 and the support plate 12 more secure. By screwing the bolts 39 into the positioning holes 14, the position of the L-arm 36 can be adjusted to achieve cleaning or retraction.

[0041] Since a lot of dust may be generated at the work site, the bearing connections and rotating connections are sealed to prevent dust from entering.

[0042] The workflow of this embodiment is as follows:

[0043] During line marking, the L-arm 36 is aligned parallel to the length of the vehicle 11. Bolts 39 are screwed into the corresponding positioning holes 14. As the vehicle 11 moves, the motor 38 is activated. The motor 38 drives the slide rail 313 to swing, which in turn drives the power rod 314 to move along the straight groove 34. This movement of the power rod 314 along the slide rail 313 drives the vertical tube 311 to move, which in turn drives the T-rod 310 to move along the guide rod 37. When the power rod 314 moves along the two semi-circular grooves of the straight groove 34, the vertical tube 311 moves along the T-rod 310. The vertical tube 311 drives the cleaning brush 312 to move. When the power rod 314 moves along the lower straight groove, the cleaning brush 312 contacts the ground, clearing debris to the side closer to the vehicle 11 and creating the marked area.

[0044] Example 3: This example further elaborates on Example 2. The cleaning component 3 also includes a vacuum cleaner 35 and a vacuum hood 33. The vacuum cleaner 35 is installed on the front of the vehicle 11 near the support plate 12. The vacuum hood 33 is fixedly connected to a vacuum connector 31, which is connected to the L-arm 36. This allows the vacuum hood 33 to flexibly follow the movement of the L-arm 36, ensuring that the vacuum hood 33 always fits tightly against the ground and effectively absorbs impurities. The vacuum cleaner 35 and the vacuum connector 31 are connected by a corrugated pipe. The flexibility of the corrugated pipe ensures that the connection between the vacuum cleaner 35 and the vacuum connector 31 is not affected by the movement of the L-arm 36, avoiding air leakage and insufficient suction during vacuuming.

[0045] Preferredly, the vacuum cleaner 35 is mounted on the vehicle 11 by a rotating connection, and the position of the vacuum cleaner 35 can be locked by means of clips and bolts.

[0046] The design of the vacuum hood 33 takes into account the fit to the ground and the vacuuming efficiency, ensuring that impurities can be collected to the maximum extent during the vacuuming process, further improving the cleanliness of the road marking area.

[0047] The workflow of this embodiment is as follows:

[0048] When vehicle 11 moves, vacuum cleaner 35 is turned on, and cleaning brush 312 cleans the impurities to the area below vacuum hood 33 (the cleaning brush 312 deforms upon contact with vacuum hood 33), and vacuum cleaner 35 absorbs the impurities.

[0049] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
