Abstract
Description
Technical Field
[0001] This utility model relates to the field of line marking devices, and more specifically, to a line marking device for highway design. Background Technology
[0002] After highway construction is completed, it is necessary to use marking devices to design lines, arrows, text, vertical markings, raised pavement markers and delineators on the highway to convey traffic information such as guidance, restrictions and warnings to traffic participants. Before the marking work is carried out, it should be noted that the sand and debris on the road surface have been cleaned up.
[0003] When marking lines, the road edge lines are usually close to the curb. When drawing arcs or straight lines around them, workers need to manually maintain the distance between the road edge lines and the curb. This results in narrow space and obstructed vision due to the presence of the curb on the side, making it difficult for workers to observe. Consequently, the marking speed is slow and the work efficiency is insufficient. In view of this, we propose a marking device for highway design. Utility Model Content

A fixing sleeve 6 is fixedly connected to the upper surface of the base 1. A first adjusting plate 7 is slidably fitted inside the fixing sleeve 6. Both sides of the first adjusting plate 7 extend to the outside of the fixing sleeve 6.

The first adjustment plate 7 is provided with a spacing adjustment component. The position of the contact wheel 8 can be adjusted by the first adjustment plate 7, so that when marking the edge line of the curb, the contact wheel 8 can contact the curb for auxiliary marking without deliberately controlling or observing the spacing between the marking nozzle 4 and the curb, which can effectively increase the speed of marking the edge line of the road.
[0030] Example 2
[0031] The road marking device for highway design provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the spacing adjustment assembly includes a first scale 12 for auxiliary adjustment, which is set on the front surface of the first adjustment plate 7. A second scale 13 is set on the upper surface of the first adjustment plate 7. A first locking bolt 14 for fixing is set on the upper surface of the fixing sleeve 6. The lower end of the first locking bolt 14 is threaded through the interior of the fixing sleeve 6 and contacts the upper surface of the first adjustment plate 7. A second locking bolt 15 for fixing is set on the rear surface of the second adjustment plate 10. The end of the second locking bolt 15 is threaded through the second adjustment plate 10 and contacts the first adjustment plate 7. A drive shaft 16 for power transmission is fixedly connected between the two front moving wheels 2.
[0032] A first synchronous wheel 17 is fixedly sleeved on the outer surface of the drive shaft 16. A rotating shaft 18 is rotatably connected to the lower surface of the base 1. A sweeping disc 19 is fixedly connected to the lower end of the rotating shaft 18. A brush 20 for pushing away garbage is provided on the lower surface of the sweeping disc 19. A protective box 21 for protecting the internal structure is fixedly connected to the upper surface of the base 1. The upper end of the rotating shaft 18 rotatably penetrates into the interior of the protective box 21. A bevel gear 22 is fixedly connected to the upper end of the rotating shaft 18. An installation plate 23 for installation is fixedly connected to the upper surface of the base 1. A connecting shaft 24 is rotatably connected to the front surface of the installation plate 23.
[0033] The front end of the connecting shaft 24 rotates through the interior of the protective box 21. The front end of the connecting shaft 24 is also fixedly connected to a bevel gear 22 for power transmission. The two bevel gears 22 mesh with each other. A through groove 25 extending to the lower surface of the base 1 is provided on the upper surface. A second synchronous wheel 26 is fixedly sleeved on the outer surface of the connecting shaft 24. A synchronous belt 27 is provided between the second synchronous wheel 26 and the first synchronous wheel 17. During the movement of the marking device, the rotation of the moving wheel 2 can indirectly drive the sweeping disc 19 to rotate, thereby sweeping away fallen leaves or dust in the marking area and improving the quality of the marking.
[0034] The usage process of the highway design marking device provided by this utility model is as follows:
[0035] When marking lines on a normal road surface, only the adjusting wheel 11 needs to be moved to the outside of the marking area. Then, when the worker pushes the marking device, they can observe the position of the adjusting wheel 11 relative to the auxiliary line during marking, thus preventing deviation from the intended route. Simultaneously, as the moving wheel 2 moves, it synchronously drives the drive shaft 16 to rotate. The rotation of the drive shaft 16 then synchronously drives the first synchronous pulley 17 to rotate. This, in turn, through the cooperation of the first synchronous pulley 17, the second synchronous pulley 26, and the synchronous belt 27, drives the connecting shaft 24 to rotate. The rotation of the connecting shaft 24, in turn, through the cooperation of two bevel gears 22, drives the rotating shaft 18 to rotate. After the device is activated, it can simultaneously drive the sweeping disc 19 and the brush 20 to rotate, thereby using the brush 20 to sweep away the remaining fallen leaves on the marked area. When marking the edge line of the curb, the marking nozzle 4 can be aligned with the marking area first. Then, by loosening the first locking bolt 14 and adjusting the position of the first adjusting plate 7, the contact wheel 8 will contact the curb after the first adjusting plate 7 is adjusted. At this time, the first locking bolt 14 is tightened again to lock the position of the first adjusting plate 7. Then, the marking device can be directly pushed to move along the curb. During the movement, it is only necessary to keep the contact wheel 8 in close contact with the curb.
