Technical Field

[0001] The utility model relates to a line marking device, in particular to a bridge road surface line marking device, belonging to the technical field of bridge construction. Background Technique

[0002] Bridge construction is the process of building a bridge according to the design content, mainly referring to bridge construction technology, construction organization, construction management, construction quality, etc. After the main construction of the bridge is completed, line marking operations need to be carried out on the bridge deck. Lines, arrows, words, elevation markings, raised road markings, and contour markings are used to convey traffic information such as guidance, restriction, and warning to traffic participants. Its function is to control and guide traffic.

[0003] The existing road and bridge line marking devices usually include a placement box, universal wheels, a push rod, a liquid storage cavity, and a liquid spraying head. During use, the overall movement of the device is controlled by the push rod, and the pigment in the liquid storage cavity is sprayed by the liquid spraying head to mark the ground. However, when the existing technology is used for line marking operations on the road surface, the drawn lines cannot be dried, and they need to dry automatically, resulting in a long drying process. The drawn lines are easily scratched, affecting the line marking forming rate of the device. At the same time, there is a lack of cleaning of the road surface before line marking, so the dust on the bridge road surface will affect the line marking quality.

[0004] Therefore, a bridge road surface line marking device is proposed here. Content of the Utility Model
