Description

Road surface cleaning device

Technical Field

The utility model belongs to the sanitation field, concretely relates to road surface cleaning device.

Background

In the sanitation industry, sanitation vehicles or devices such as cleaning and sweeping vehicles, pavement maintenance vehicles, or washing vehicles are generally used to clean the road surface. The use of the special vehicles greatly reduces the labor intensity of sanitation workers and improves the working efficiency. On one hand, with the continuous increase of the quantity of automobiles in China and the shortage of parking space resources, a large number of automobiles are often parked beside a road, and the phenomenon of parking beside a town road is more serious; on the other hand, the demands for environmental hygiene are constantly increasing throughout society. Therefore, the problem of cleaning the underbody pavement of the roadside parked vehicles increasingly draws attention of citizens, government departments and environmental sanitation enterprises, and urgent needs for mechanization and automation of the underbody pavement cleaning operation of the roadside parking are brought forward.

At present, nozzles or nozzles of sanitation vehicles or devices for cleaning road surfaces are basically fixedly installed, the spraying angle of the nozzles or nozzles is fixed during operation, or even if the angle can be adjusted, the nozzles are simply adjusted manually before formal operation, and the nozzles are fixed after the adjustment. Therefore, the current sanitation vehicles or devices are mainly applied to open space type road surfaces on which no vehicles or obstacles are parked, and cannot clean the underbody such as roadside parking or have poor cleaning effect.

At present, temporary solutions for cleaning the road surface of the vehicle bottom of the roadside parking mainly depend on sanitation workers to carry out manual cleaning or cleaning, so that the temporary solution is high in labor intensity, high in repeatability, boring in work and low in efficiency, and is inconsistent with the development direction of mechanization and automation in the sanitation industry. Sanitation workers need to repeatedly bend down to stretch cleaning tools such as brooms or handheld spray guns into the bottoms of roadside parking vehicles for operation, and long-time work can cause that the body parts of the workers such as knees, lumbar vertebrae or shoulders are easily changed into occupational diseases due to strain, so that the sanitation workers are not good for physical and mental health, and the medical and national medical insurance expenditure burden is increased. The nozzle that adopts sanitation vehicle to carry on fixed angle carries out vehicle bottom road surface washing operation also, but because the road all has certain radian and each vehicle that the roadside berthhed is also different apart from the distance of roadside when the road is laying, lead to only having the washing effect in the limited length within range after the water jet that spouts from the fixed angle nozzle strikes the road surface, then owing to keep away from the direct hitting point of water jet to the road surface at the farther end of nozzle, and lead to the impact force to weaken and play the washing effect to the road surface, the operation requirement that can not cover whole vehicle bottom road surface and possess high hitting power has been satisfied.

Meanwhile, with the continuous reciprocating swing of the nozzle, the hitting point of the water jet on the underbody pavement also continuously reciprocates along the width direction of the vehicle body of the vehicle parked on the road; along with the traveling of the moving platform along the road direction, the hitting point of the water jet on the underbody also moves along the length direction of the vehicle body of the vehicle parked on the road, namely the road direction. After the motions in the two directions are synthesized, the water jet can comprehensively wash or clean the whole vehicle bottom road surface area parked at the roadside by the water jet which has water flow with certain width and impact force and is formed by striking points and impact scattering of the vehicle bottom road surface.
