Description

Road sweeper

Technical Field

The invention relates to the technical field of road sweeping, in particular to a road sweeper.

Background

At present, when a road or a bridge is constructed, road expansion joints are reserved on the road surface of the road, and road expansion joints are also reserved on the bridge deck of the bridge. When the road and the bridge are used, garbage is easier to accumulate at the expansion joint than a horizontal road surface. At present, various road sweeper vehicles on the market mostly adopt vertically placed disc type sweeping brushes or long rolling brushes arranged at the rear end of the sweeper vehicle, and can not go deep into a depression to sweep garbage. Because the road sweeper needs to travel on the road surface, the height of the rolling brush is usually set at a position slightly attached to the ground, the bottom surface of the road expansion joint is lower than the road surface, and the rolling brush cannot well sweep out the garbage in the road expansion joint when rotating. Although the existing rolling brush is usually connected to the bottom of the vehicle body through the lifting rod and can also lift up and down, the structure is only used for adjusting the size of a gap between the rolling brush and the ground, people cannot accurately adjust the rolling brush when the vehicle moves to the expansion joint, and the rolling brush is embedded into the expansion joint and cleans up garbage in the expansion joint. The road expansion joint on the bridge is difficult to clean, and the efficiency of manual cleaning is lower.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a road sweeper which can prompt people in the sweeper to stop in time when a vehicle passes through an expansion joint and then clean the expansion joint; compared with the prior cleaning mode, the cleaning method is more convenient and simpler, and the efficiency is higher.

The above object of the present invention is achieved by the following technical solutions:

a road sweeper comprises a sweeper body and a mounting frame mounted on the bottom surface of the sweeper body, wherein a garbage adsorption device and a garbage sweeping device are fixedly mounted on the mounting frame, the garbage sweeping device comprises a cleaning brush for sweeping out garbage in an expansion joint and a lifting oil cylinder for controlling the cleaning brush to move up and down, an adjusting rod is hinged to the mounting frame, the rotating axis of the adjusting rod is parallel to the horizontal plane and perpendicular to the axis of the sweeper body, a rotating wheel is rotatably mounted at the lower end of the adjusting rod, the rotating axis of the rotating wheel is parallel to the rotating axis of the adjusting rod, a reset spring is connected to the adjusting rod, the other end of the reset spring is connected with the mounting frame, the reset spring is located on one side, close to a vehicle head, of the sweeper body, and the length of the adjusting rod is greater than the distance between one end, hinged to the mounting frame, of the adjusting rod and the ground; adjust the pole and install in the position department adjacent with the cleaning brush, and adjust the pole and be located one side that is close to locomotive in the cleaning brush in the automobile body, fixed mounting has proximity switch on the mounting bracket, installs the response piece that is used for triggering proximity switch on adjusting the pole, is provided with the pilot lamp in the driver's cabin in the automobile body, when adjusting the pole and rotating to vertical position, the response piece is adjacent with the proximity switch position, and makes the pilot lamp luminous.

Through adopting above-mentioned technical scheme, articulate the regulation pole on the mounting bracket because length is greater than the distance that the regulation pole articulates between the one end of mounting bracket and ground, when normally traveling subaerial, the one end that the regulation pole is connected with the rotation wheel is located the one side that the locomotive was kept away from to the one end that the regulation pole is connected with the mounting bracket. At the moment, the return spring is stretched, and the response block on the adjusting rod is dislocated with the proximity switch on the mounting frame, so that the indicator lamp in the cab does not emit light.
