Description

Technical Field

[0001] The utility model relates to the technical field of highway maintenance, in particular to a cleaning device for highway maintenance. Background Art

[0002] Highway maintenance includes maintenance during highway construction and maintenance and upkeep after highway construction. Maintenance during highway construction refers to the maintenance of roads paved with concrete or asphalt. Maintenance after highway construction focuses on the maintenance of the entire process of the highway from the time it is completed and opened to traffic, and upkeep focuses on repairing damaged parts. At present, most highway pavements are paved with concrete or asphalt. After the pavement is just paved, it is necessary to provide it with certain humidity and temperature conditions so that it can harden and increase its strength normally or at an accelerated rate. In the process of maintaining concrete or asphalt pavements, it is often necessary to sprinkle water on the pavement to maintain a certain humidity.

The beneficial effects of the patent are: the crank is driven to rotate under the rotation of the forward and reverse motor, and the two fixed blocks are driven to rotate under the cooperation of the spring and the rotating rod, so that the two water spray guns rotate and spray water; the second belt is driven under the action of the belt The first pulley rotates, the second pulley drives the rotating shaft to rotate, and the rotating shaft drives the two traveling wheels to rotate, thereby driving the box; by arranging a nozzle at one end of the two water spray guns, the water output of the two water spray guns is made more uniform, but in the structure of this patent, it is inconvenient to operate when adjusting the height of the nozzle and the ground, and it is also necessary to stop the operation, which cannot meet the use requirements. At the same time, it cannot be adaptively adjusted according to the width of the road surface. When a cleaning vehicle is used to maintain the highway during construction, part of the road surface is often not sprayed with water or is repeatedly sprayed, which makes the humidity on the road surface uneven, which is easy to have an adverse effect on the road surface maintenance. Therefore, a cleaning device for highway maintenance is proposed to address the above shortcomings. Utility Model Content
