Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, and particularly relates to a spraying device for road and bridge maintenance. Background Technique

[0002] Road and bridge refer to roads and bridges. In our daily life, roads and bridges can be seen everywhere. They are layered structures paved with various road construction materials or mixtures for vehicles to drive on. Their function is to ensure that vehicles can run all-weather, stably, at high speed, comfortably, safely and economically on the road. Roads and bridges are prone to dust accumulation. In order to clean this dust, it is necessary for workers to regularly carry out maintenance spraying work, and at this time, a spraying device is needed.

[0003] Most of the existing spraying devices use spray guns to spray water on the surfaces of roads and bridges for dust removal. For example, the utility model patent with the publication number of CN215714492U discloses a spraying device for road and bridge maintenance, which includes a pushing plate. There are multiple rollers on the pushing plate. Two push handles are fixedly connected to the pushing plate. A water supply component is fixedly connected to the pushing plate. Two lifting mechanisms are connected to the pushing plate. The same limiting mechanism is connected to the two lifting mechanisms. An input mechanism connected to the water supply component is connected to the limiting mechanism. A rotating mechanism is connected to the input mechanism. A blocking mechanism is connected to the input mechanism.

[0004] In the above-mentioned prior art, during use, the angle and height of the water spray head can be adjusted to maintain the roads with different widths of cement surfaces, eliminating the need for workers to pull water pipes for spraying maintenance, thus facilitating the spraying maintenance work of workers. However, during the spraying maintenance process, the angle of the water spray head is fixed, and during the movement of the pushing plate, it is easy to affect the water spraying uniformity of the water spray head on the roads and bridges due to the change in the movement speed of the pushing plate, resulting in water accumulation.
