Description

Technical Field

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

[0002] Traffic markings, as a key component of road traffic safety facilities, bear the important responsibility of regulating and guiding traffic. With the continuous advancement of infrastructure construction in my country, the demand for traffic markings is increasing daily, and the marking work faces numerous challenges, including a massive workload, complex procedures, and lengthy processing times. Against this backdrop, the performance of marking devices directly affects the quality and efficiency of marking construction.

[0003] Currently available road marking devices primarily work by spraying paint onto the road surface through nozzles to create various traffic markings. However, these devices exhibit significant shortcomings when dealing with sloping surfaces. When the device moves across a slope to apply road markings, the lack of an effective mechanism to adjust the distance between the nozzle and the ground causes the distance to change as the slope fluctuates, especially when the slope lies between the front and rear wheels (e.g., where there are depressions or bumps in the ground between the wheels). This variation results in inconsistent marking widths, with some areas having markings that are too wide or too narrow. This can affect the visual standardization and recognizability of the markings, hindering the clear and accurate transmission of traffic guidance information, reducing their intended traffic instruction function, and ultimately posing a potential threat to road safety.

[0004] Therefore, it is necessary to provide a road marking device to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a road marking device that solves the problem that the distance between the nozzle and the ground changes when the ground slope fluctuates and the slope is between the front and rear moving wheels (such as when there is a depression or bump in the ground between the two wheels).

[0006] To solve the above-mentioned technical problems, the present invention provides a marking device comprising: a material tank, a base plate, and a heating tank. The material tank is disposed on the top of the base plate and is used to store the marking paint. The heating tank is disposed on the side of the base plate near the output end of the material tank. An undulating rod is fixedly connected to the side of the base plate near the output end of the material tank. A fixing sleeve is provided on the outer surface of the undulating rod, and the fixing sleeve is fixedly connected to the base plate. An undulating groove is provided inside the fixing sleeve, and the undulating rod is slidably connected inside the undulating groove. A connecting block is fixedly connected to the side of the undulating rod near the heating tank, and the connecting block is connected to the heating tank. When the undulating rod moves up and down inside the fixing sleeve, it can drive the heating tank to move up and down together.

[0007] Preferably, a spring sheet is provided between the top of the inner surface of the undulating groove and the top of the undulating rod, and an undulating wheel is installed at the bottom of the undulating rod. When the undulating wheel rolls on the undulating terrain, the spring sheet will compress or extend, and the undulating rod will move up and down within the fixed sleeve.

[0008] Preferably, the top of the material tank is provided with a tank cover, and a cover handle is fixedly connected to the top of the tank cover. A motor is fixedly connected to the top of the bottom plate, and the motor is located directly below the material tank. A rotating rod is fixedly connected to the drive end of the motor.

A connecting pipe is fixedly connected to the bottom of the material tank, and the connecting pipe is connected to the output end of the material tank.

[0009] Preferably, a pusher is fixedly connected to one side of the top of the base plate, and the pusher is located at the end of the top of the base plate away from the material tank. A push handle is fixedly connected to the top of the pusher for pushing the device. A control plate is fixedly connected at the connection between the pusher and the push handle. Four wheel columns are provided at the bottom of the base plate.

[0010] Preferably, a delivery pump is installed on the top of the base plate. The delivery pump is located between the material tank and the heating tank, and one end of the delivery pump is connected to a pipe, while the other end is fixedly connected to a hose. The delivery pump can be used to extract the paint from inside the material tank to the heating tank.

[0011] Preferably, the top of the heating tank is provided with a dust cover, and the top of the dust cover has a material inlet connected to a hose. The hose introduces the paint. The bottom of the heating tank is provided with a marking mold head. Two guide plates are fixedly connected to the side of the heating tank near the bottom plate.

[0013] Preferably, a toolbox is provided on the top of the base plate for storing the tools needed for marking, and a power source is also provided on the top of the base plate.

[0014] Compared with related technologies, the marking device provided by this utility model has the following beneficial effects:

[0015] When the device operates on undulating ground, the undulating wheel at the bottom of the undulating rod rolls on the ground. As the ground undulates, the undulating rod moves up and down within the undulating groove of the fixed sleeve, driving the heating tank to move up and down along with it via the connecting block. When encountering a raised area between the two wheels, the undulating rod moves upward, causing the heating tank to move upward; when encountering a recessed area between the two wheels, the undulating rod moves downward, causing the heating tank to move downward. This ensures that the spray nozzle of the heating tank maintains a relatively stable height relative to the ground, preventing inconsistent width of the sprayed markings due to changes in ground slope. This guarantees the consistency of the marking width, improves the visual standardization and recognition effect of the markings, and enables the markings to convey traffic guidance information more clearly and accurately, fully playing their role in traffic indication and ensuring road traffic safety.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 4A road marking device includes: a material tank 10, a base plate 20, a delivery pump 30, a heating tank 40, an undulating rod 50, a cleaning air box 60, a toolbox 70, and a power source 80. The material tank 10 is located on top of the base plate 20 and is used to store the paint for road marking. The delivery pump 30 is installed on top of the base plate 20, and its input end is connected to the output end of the material tank, for delivering the paint inside the material tank 10 to the heating tank 40. The heating tank 40 is located on the side of the base plate 20 near the output end of the material tank 10. The device is used to heat and spray the paint output from the material tank 10. The undulating rod 50 is located between the base plate 20 and the heating tank 40. When the device is applied to undulating ground, it can drive the heating tank 40 to move up and down, so that the spray nozzle of the heating tank 40 is always at the same height as the ground. The cleaning air box 60 is set on the side of the base plate 20 near the output end of the material tank 10. The tool box 70 is set on the top of the base plate 20 for storing tools. The power source 80 is set on the top of the base plate 20 for providing power output to the device.

[0023] A fixing sleeve 51 is provided on the outer surface of the undulating rod 50. The fixing sleeve 51 is fixedly connected to the base plate 20. An undulating groove 511 is opened inside the fixing sleeve 51. The undulating rod 50 is slidably connected to the inside of the undulating groove 511.

An undulating wheel 502 is installed at the bottom of the undulating rod 50. When the undulating rod 50 moves up and down in the fixing sleeve 51 due to the undulation of the ground, it can drive the heating tank. The heating tank 40 moves up and down together. When the device moves, the ground may be uneven. The heating tank 40 is located on the undulating rod 50. The undulating wheel 502 at the bottom of the undulating rod 50 will roll on the uneven ground. When it encounters a high ground, the spring piece 52 at the top of the undulating rod 50 will be compressed, and the undulating rod 50 will move upward, driving the heating tank 40 to move upward, ensuring that the height of the spray nozzle of the heating tank 40 remains relatively constant with respect to the ground. When it encounters a low ground, the spring piece 52 will extend, and the undulating rod 50 will move downward. The heating tank 40 will move downward synchronously. A damping pad is provided between the fixing groove and the undulating rod 50 to prevent the heating tank 40 from suddenly falling back.

[0024] The top of the material tank 10 is provided with a lid 11, and a lid handle 111 is fixedly connected to the top of the lid 11 for easy removal of the lid 11 and addition of paint to the material tank 10.

The marking head 41 is used to draw the marking lines. The inner wall of the heating tank 40 is equipped with a heating wire to heat the paint in the tank, which facilitates the subsequent marking of the lines.

[0028] Two guide plates 42 are fixedly connected to the side of the heating tank 40 near the bottom plate 20. Guide rods 421 are fixedly connected to the bottom of the two guide plates 42, and the guide rods 421 pass through the bottom plate 20. When the heating tank 40 moves up and down, the guide rods 421 force the heating tank 40 to make linear motion.

[0029] The cleaning air box 60 is installed on the side of the base plate 20 near the heating tank 40, and the cleaning air box 60 is located in front of the heating tank 40. A connecting rod 61 is fixedly connected to the side of the cleaning air box 60 near the base plate 20. The cleaning air box 60 is fixedly connected to the base plate 20 through the connecting rod 61. An air blowing port 62 is opened on the side of the cleaning air box 60 away from the heating tank 40. The cleaning air box 60 can blow out gas to clean the area to be marked. The cleaning air box 60 is equipped with an air blowing fan to generate cleaning airflow.

[0030] The toolbox 70 is located on the top of the base plate 20 and can hold the tools needed for marking, such as spare hoses 31. The power source 80 is also located on the top of the base plate 20 and is used to provide power for the motor 12, delivery pump 30, heating tank 40, cleaning air box 60, etc. of the device.

[0031] The working principle of the road marking device provided by this utility model is as follows:

[0032] When the device moves and operates on uneven ground, the undulating wheel 502 at the bottom of the undulating rod 50 remains in contact with the ground and rolls forward along the terrain. When it encounters a raised area between the two wheels, the undulating wheel 502 presses upward against the undulating rod 50. At this time, the spring piece 52 located between the top of the inner surface of the undulating groove 511 and the top of the undulating rod 50 is compressed under pressure, and the undulating rod 50 moves upward under the force of compression. The upward movement of the undulating rod 50 causes the heating tank 40 to move upward synchronously. Conversely, when encountering a lower terrain area, the previously compressed spring piece 52 expands and recovers due to reduced pressure. Under the action of the expansion force, the undulating rod 50 moves downward, thereby causing the heating tank 40 to move downward as well. Meanwhile, the guide rod 421, acting like a track, restricts and guides the heating tank 40 to move only in a straight line, up and down. In this way, regardless of the terrain's undulations, the height of the heating tank 40 can be precisely adjusted through the coordinated action of the undulation rod 50, the spring piece 52, and the guide rod 421, ensuring that the spray nozzle of the heating tank 40 always maintains a relatively stable and suitable height relative to the ground. This effectively avoids inconsistencies in the width of the sprayed markings due to changes in ground slope during the entire marking process, thus ensuring the uniformity of the marking width and greatly improving the quality of the marking application.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
