Description

TECHNICAL FIELD

[0001] The present application relates to road traffic construction device technical field, especially a tar road marking water line stable marking device. BACKGROUND

[0002] With the rapid development of highway construction in China, the road marking line construction is more and more, and the tar road marking line construction first needs standard line setting out, that is, water line marking construction, and the water line marking requires accuracy, otherwise it will affect the marking line construction quality.

[0003] At present, the traditional manual marking has been eliminated, and the water line construction is usually marked by water line vehicle, when the water line vehicle marks, since the support arm supporting the paint nozzle has a certain length, due to the flatness of the tar road, the paint nozzle will inevitably vibrate and shake, the distance between the paint nozzle and the ground cannot be completely stable, and when the distance between the paint nozzle and the ground is too large, the wind power will also cause a large error in the water line setting out. SUMMARY

[0004] In order to overcome the technical problems in the background art, the present application provides a tar road marking water line stable marking device.

[0006] Further, the cutting edge of the ground cutter is arc-shaped, the arc-shaped cutting edge can smoothly cut into the tar road surface, the friction is small, and the jumping is not easy, and the moving track stability is good.

[0007] Further, the water line paint nozzle in the paint nozzle fixing sleeve is connected with the adjusting screw rod, the water line paint nozzle for water line marking follows the track of the ground cutter, and is stable and controllable.

[0008] Further, the water line paint nozzle and the ground cutter perpendicular to the ground are installed in parallel. The water line paint nozzle for water line marking always keeps parallel and equidistant with the ground cutter and perpendicular to the ground during marking, the track of the water line drawn by the water line paint nozzle and the ground cutter on the tar road surface is parallel, the water line marking construction has high accuracy and good stability.

[0009] Further, the installation height of the water line paint spray pipe can be adjusted up and down in the paint spray nozzle fixing sleeve according to the wind conditions at the construction site, so that the height of the bottom nozzle of the water line paint spray pipe relative to the asphalt ground can be adjusted to avoid the deviation of the line caused by the wind and improve the accuracy and stability of the water line drawing.

[0010] Further, the floor cutter is made of hard alloy steel, which has high hardness, high wear resistance and high heat resistance. The high-hardness cutter blade can cut into the asphalt ground, and the high wear resistance and high heat resistance can keep the cutter blade from deforming during long-time friction with the asphalt ground, thereby keeping the running track stable.

[0011] The implementation process is as follows: first, the fixed seat is connected and installed with the line drawing vehicle, one end of the connecting rod is connected with the fixed seat through a bearing, and the other end is connected with the floor cutter which depends on its own gravity and hangs on the asphalt ground.

The water line paint spray pipe is parallel to the floor cutter and also perpendicular to the asphalt ground. The installation height of the bottom nozzle of the water line paint spray pipe relative to the asphalt ground can be adjusted to 2-10 mm according to the wind conditions at the construction site, so that the distance between the nozzle of the water line paint spray pipe and the asphalt ground is kept fixed to avoid the disturbance of the wind to make the paint flow deviate in the air, thereby causing the line to deviate and improving the accuracy and stability of the water line drawing.

[0012] The line drawing vehicle runs along the set route and drags the floor cutter. Since the hardness of the floor cutter is much higher than that of the asphalt road, the bottom blade of the floor cutter can cut into the surface of the asphalt road by gravity. The floor cutter slides on the asphalt road, forming a sliding effect similar to that of an ice cutter cutting into the ice surface and keeping a stable track on the ice surface. The floor cutter keeps a stable running track on the asphalt road without horizontal shaking and vertical jumping. The water line drawn by the water line paint spray pipe beside the floor cutter is also very accurate and stable, thereby realizing high-quality water line construction.

[0013] The connecting rod is connected with the fixed seat through a bearing, and the floor cutter depends on gravity and cuts into the surface of the asphalt road with the bottom blade. The shaking and shaking of the line drawing vehicle and the connecting rod can be filtered and transmitted. The cutter blade of the floor cutter cuts into the asphalt ground in a shallow layer and slides away from the asphalt road, forming a stable sliding effect similar to that of an ice cutter on the ice surface. The running track is stable without horizontal shaking and vertical jumping. The water line drawn by the water line paint spray pipe beside the floor cutter is also accurate and stable, thereby greatly improving the accuracy and stability of the water line drawing construction. At the same time, the cutter blade of the floor cutter only cuts into the surface layer of the asphalt road by gravity, without damaging the asphalt road.

[0014] The installation height of the waterline paint spray pipe from the asphalt pavement can be adjusted according to the wind condition on site, the distance between the waterline paint spray pipe and the ground can be kept fixed, the paint is prevented from being deflected in the air due to wind disturbance, the waterline marking accuracy and stability are improved.
