Coating spraying device and method for road maintenance

Abstract

The invention discloses a coating spraying device for road maintenance, and belongs to the technical field of road maintenance equipment. The device comprises a vehicle body and a material barrel, thematerial barrel is fixedly mounted on the outer wall of the top of the vehicle body, two groups of openings are formed in the outer wall of the bottom of the vehicle body, and two groups of guide devices are arranged on the outer wall of the bottom of the vehicle body; the guide device comprises guide rods slidably inserted into the inner cavities of the openings, guide wheels are fixedly mountedat the bottom ends of the guide rods, a spraying head is arranged between the two guide rods, and the end, away from the spraying head, of the hose extends to the outer wall of the top of the vehiclebody and communicates with the outer wall of the right side of the material barrel. The guide whees and the spraying head in the device are located on the same horizontal line, the guide wheels drivethe guide rods to move up and down in the inner cavity of the openings, the spraying head can change along with the height change of the road surface, and therefore the distance between the sprayinghead and the marking area is kept unchanged, and uneven marking spraying caused by factors of the road surface is avoided.

Description

technical field [0001] The invention relates to the technical field of road maintenance equipment, in particular to a paint spraying device and a spraying method for road maintenance. Background technique [0002] In the process of highway maintenance, it is necessary to re-mark the damaged or blurred marking area. When using the paint spraying device to mark the line, first remove the old marking, and then push the car body through the spraying head of the device. Spray the paint to the construction area and mark the construction area. In order to ensure the quality of the line, it is necessary to adjust the distance between the spray head and the road surface before construction so that the width and thickness of the marking line meet the standard. However, adjust The final spraying head will not change during the process of device moving and marking, because the road surface is not level, and the pulleys of the vehicle body and the spraying head are not on the same horizo...

[0002] In the process of highway maintenance, it is necessary to re-mark the damaged or blurred marking area. When using the paint spraying device to mark the line, first remove the old marking, and then push the car body through the spraying head of the device. Spray the paint to the construction area and mark the construction area. In order to ensure the quality of the line, it is necessary to adjust the distance between the spray head and the road surface before construction so that the width and thickness of the marking line meet the standard. However, adjust The final spraying head will not change during the process of device moving and marking, because the road surface is not level, and the pulleys of the vehicle body and the spraying head are not on the same horizontal line, when the vehicle body pulley and the spraying head correspond When the height of the road surface is different, the distance between the spraying head and the construction area will change, resulting in changes in the width and thickness of the sprayed markings, which will affect the quality of the markings. Therefore, we propose a paint spraying device for road maintenance and spraying method
