[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-7 As shown in the figure, this embodiment provides an embodiment of a road marking device for highway engineering.

[0027] A road marking device for highway engineering includes a support plate 1 and casters 2. A marking structure 3 is mounted on the support plate 1. The marking structure 3 includes a paint placement box 4 fixedly installed on the top of the support plate 1. A pneumatic diaphragm pump 5 is fixedly installed at one end of the paint placement box 4. A buffer tank 6 is fixedly installed on the support plate 1. The pneumatic diaphragm pump 5 and the buffer tank 6 are connected by a connecting pipe 7. A fixing frame 8 connected to the support plate 1 is fixedly installed on one side of the paint placement box 4. A first drive motor 9 is fixedly installed on the top of the fixing frame 8. A first lead screw 10 is fixedly installed at the output end of the first drive motor 9. A transmission block 11 is mounted on the first lead screw 10. A connecting frame 12 is fixedly installed at the bottom of the transmission block 11. A marking assembly 13 is fixedly installed on the connecting frame 12. A telescopic pipe 14 is installed between the buffer tank 6 and the marking assembly 13.

[0028] The bottom of the marking assembly 13 is provided with a paint outflow groove 15. A second lead screw 16 is provided on the connecting frame 12, and a connecting block 17 is installed on the second lead screw 16. Stabilizing frames 18 are fixedly installed at both ends of the second lead screw 16. A spacing plate 19 is fixedly installed at one end of the stabilizing frame 18. A first gear 20 is fixedly installed on the second lead screw 16. A second drive motor 21 is fixedly installed on the top of the connecting frame 12. A second gear 22 that meshes with the first gear 20 is fixedly installed at the output end of the second drive motor 21. A fan 23 is fixedly installed at one end of the support plate 1. A dust blowing head 24 is provided at the bottom of the fan 23.

[0029] By setting up the marking structure 3, the traditional manual marking method, such as using a handheld marking bucket with adjustable thickness and width baffles, brushes, rollers, or small manual spray guns, is changed. First, the paint needed for marking is added into the paint storage box 4. Then, the pneumatic diaphragm pump 5 is started. Compressed air drives the diaphragm inside the pneumatic diaphragm pump 5 to reciprocate. The paint is sucked from the paint storage box 4 by negative pressure and pushed to the connecting pipe 7 by positive pressure. The paint then enters the buffer tank 6 through the connecting pipe 7 for buffering. Its function is to reduce the pulse generated when the pneumatic diaphragm pump 5 is working, stabilize the paint delivery pressure, and avoid the impact of excessive pressure fluctuations on subsequent equipment or spraying processes. At the same time, it can also store paint to a certain extent to ensure the continuity of paint supply. Then, the paint inside the buffer tank 6 enters the marking assembly 13 through the telescopic pipe 14.

[0030] At this time, the first drive motor 9 is started, driving the first lead screw 10 to rotate. When the first lead screw 10 rotates, the transmission block 11 drives the connecting frame 12 to move. When the connecting frame 12 drives the marking assembly 13 to descend, so that the position of the paint outlet 15 is close to the ground, the paint can flow into the ground through the paint outlet 15 to mark the lines. Personnel only need to push the support plate 1 to move it under the action of multiple casters 2 to mark a large area. When the width of the line to be marked needs to be changed, the second drive motor 21 is started, driving the second gear 22 to rotate. Due to the connection relationship between the second gear 22 and the first gear 20, the first gear 20 can drive the second lead screw 16 to rotate synchronously when the second gear 22 rotates. At this time, the connecting blocks 17 can move closer or further apart. The stabilizer 18 can move the spacing plates 19 closer together or further apart. When the spacing of the spacing plates 19 changes, the width of the paint flowing from the paint outlet 15 for marking can also be adjusted accordingly, thus adapting to different marking widths. Before marking begins, the blower 23 can be started to blow air from the dust head 24 onto the ground, thus initially cleaning dust and impurities and preventing uneven marking due to dust or impurities. The advantages of this structure are that it can meet the time requirements of large-scale highway projects, and only one person is needed to complete the marking work. Furthermore, the adjustable spacing of the spacing plates 19 allows the equipment to be used for warning lines of different widths, saving both marking time and labor costs.

[0031] like Figures 1-7 As shown, a rotating rod 25 is movably mounted on the paint placement box 4, and multiple stirring rods 26 are fixedly mounted on the rotating rod 25. A third gear 27 is fixedly mounted on the top of the rotating rod 25, and a third drive motor 28 is fixedly mounted on the top of the paint placement box 4. A fourth gear 29 that meshes with the third gear 27 is fixedly mounted on the output end of the third drive motor 28.

[0032] With the arrangement of the rotating rod 25, stirring rod 26, third gear 27, third drive motor 28, and fourth gear 29, after the paint is poured into the paint placement box 4, the third drive motor 28 is started to drive the fourth gear 29 to start rotating. Due to the connection between the fourth gear 29 and the third gear 27, the third gear 27 also rotates synchronously when the fourth gear 29 rotates. When the third gear 27 rotates, the rotating rod 25 drives multiple stirring rods 26 to start stirring the paint. On the one hand, the paint can be fully stirred and mixed according to the specified ratio, so that the paint reaches a uniform state. On the other hand, the continuous stirring of the paint can prevent the mixed paint from solidifying and clumping.

[0033] like Figures 1-7As shown, a protective shell 30 is fixedly installed on the outer side of the third drive motor 28. The protective shell 30 has multiple heat dissipation holes 31. A maintenance cover 32 is provided at one end of the protective shell 30. A first magnetic ring 33 is fixedly installed on the inner side of the maintenance cover 32. A second magnetic ring 34, which is magnetically connected to the first magnetic ring 33, is fixedly installed on the protective shell 30.

[0034] The protective shell 30, heat dissipation holes 31, and inspection cover 32 effectively protect the third drive motor 28 from impact damage. The multiple heat dissipation holes 31 on the protective shell 30 dissipate the heat generated by the third drive motor 28, preventing overheating and potential malfunction. The inspection cover 32 allows for easy maintenance of the third drive motor 28 without disassembling the protective shell 30, saving time. The first magnetic ring 33 and the second magnetic ring 34 attract each other, securing the inspection cover 32 to one end of the protective shell 30 and preventing it from falling off. Due to the characteristics of the first and second magnetic rings, the inspection cover 32 can be opened simply by pulling it without tools, further saving time.

[0035] like Figures 1-7 As shown, limit plates 35 are fixedly installed at both ends of the paint placement box 4. A sealing plate 36 connected to the paint placement box 4 is movably installed between the limit plates 35. The paint placement box 4 has multiple mounting holes 37. A first spring 38 connected to the sealing plate 36 is fixedly installed inside the mounting holes 37. A sliding groove 39 is provided on the limit plate 35. A sliding rod 40 connected to the sealing plate 36 is movably installed inside the sliding groove 39. A fixing frame 41 is fixedly installed at one end of the limit plate 35. An insert rod 42 connected to the sliding rod 40 is movably installed on the fixing frame 41. A second spring 43 connected to the fixing frame 41 is wound around the insert rod 42.

[0036] With the arrangement of the limiting plate 35, sealing plate 36, mounting hole 37, first spring 38, slide groove 39, and slide rod 40, when paint needs to be added to the paint placement box 4, pulling the sealing plate 36 will extend the first spring 38, thus opening the sealing plate 36. After the paint is added, releasing the sealing plate 36 allows it to return to its original position under the elastic tension of the multiple first springs 38, thereby closing the sealing plate 36 again. This saves time for personnel to close the sealing plate 36. Furthermore, the sealing plate 36 is positioned within the slide groove 39 and slide rod 40. The combination of these components reduces the friction between the sealing plate 36 and the limiting plate 35, making it easier for personnel to pull the sealing plate 36. With the setting of the fixing frame 41, the insert rod 42, and the second spring 43, when the sealing plate 36 is in the closed state, the insert rod 42 can be engaged with the slide rod 40 under the elastic action of the second spring 43, thereby limiting and fixing the slide rod 40, thus improving the stability of the slide rod 40 in the slide groove 39. After pulling the insert rod 42 to disengage it from the inside of the slide rod 40, personnel can push and pull the sealing plate 36 normally.

[0037] In this embodiment, as Figures 1-7 As shown in the figure, the working process of a road marking device for highway engineering provided in this embodiment is as follows:

[0038] First, the paint needed for marking is added to the paint storage tank 4. Then, the pneumatic diaphragm pump 5 is started. Compressed air drives the diaphragm inside the pump to reciprocate, drawing the paint from the tank 4 under negative pressure and pushing it to the connecting pipe 7 under positive pressure. The paint then enters the buffer tank 6 through the connecting pipe 7 for buffering. The buffer tank 6 serves to reduce the pulses generated by the pneumatic diaphragm pump 5, stabilize the paint delivery pressure, and prevent excessive pressure fluctuations from affecting subsequent equipment or the spraying process. It also stores the paint to a certain extent, ensuring... The paint supply is continuous, and then the paint inside the buffer tank 6 enters the interior of the marking assembly 13 through the telescopic tube 14. At this time, the first drive motor 9 is started to drive the first lead screw 10 to start rotating. When the first lead screw 10 rotates, it can cause the transmission block 11 to drive the connecting frame 12 to start moving. When the connecting frame 12 drives the marking assembly 13 to descend so that the position of the paint outflow trough 15 is close to the ground, the paint can flow into the ground through the paint outflow trough 15 to mark the lines. Personnel only need to push the support plate 1 to move under the action of multiple universal wheels 2 to perform large-area marking.

[0039] When the width of the line to be drawn needs to be changed, starting the second drive motor 21 can drive the second gear 22 to start rotating. Due to the connection relationship between the second gear 22 and the first gear 20, the first gear 20 can drive the second lead screw 16 to rotate synchronously while the second gear 22 is rotating. At this time, the connecting blocks 17 can move closer or further away from each other. Therefore, the stabilizer 18 can drive the spacing plates 19 to move closer or further away from each other. When the spacing of the spacing plates 19 changes, the width of the paint flowing out of the paint outlet 15 for drawing can also be adjusted accordingly, so as to be suitable for different line widths. Before starting to draw the line, starting the fan 23 can blow air from the dust head 24 to the ground, thereby cleaning the dust and impurities on the ground in advance, thus avoiding unevenness in the line drawing due to dust or impurities.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
