Road roller capable of achieving step construction for road construction

Abstract

The invention discloses a road roller capable of achieving step construction for road construction. The road roller comprises a vehicle body, a traveling wheel is arranged at the rear end of the bottom of the vehicle body, a road rolling wheel is arranged at the front end of the bottom of the vehicle body, a supporting plate is arranged at the front end of the vehicle body, a lifting device is arranged at the left end of the upper side of the supporting plate, a lifting plate is arranged at the upper end of the lifting device, a first motor is arranged at the lower side of the lifting plate, arotating shaft is arranged at the output end of the first motor. the lower end of the rotating shaft penetrates through the supporting plate and is provided with a rotating disc, the lower side of the rotating disc is provided with a cleaning brush, the lower side of the supporting plate is provided with a protective cover located outside the rotating disc, the right part of the upper side of thesupporting plate is provided with a trash suction box, the upper part of the left side of the trash suction box is provided with a trash suction pipe, the lower end of the trash suction pipe communicates with the protective cover, the upper part of the right side of the trash suction box is provided with an exhaust port, the exhaust port is provided with a filter net, and the exhaust port is provided with a fan. The road roller is simple in structure, convenient to use, good in road rolling effect and wide in application range.

Description

technical field [0001] The invention relates to road construction, in particular to a road roller which can be used for road construction on steps. Background technique [0002] Road rollers are widely used in the construction of various roads, which use the gravity of the machine itself to make the rolled layer smooth. However, the effect of rolling the road surface only by rollers is not ideal, and local unevenness is prone to occur. In addition, when the traditional steel wheel roller is used for the initial pressing of the asphalt mixture, due to the linear contact between the steel wheel and the mixture, the contact pressure is high, and the temperature of the newly laid asphalt mixture is high and the state is loose, which often causes the mixture to push and bulge; In addition, excessive linear pressure can easily cause cracks in the asphalt mixture during the rolling process, and even break the exposed aggregate; ordinary road rollers are only suitable for flat grou...

However, the effect of rolling the road surface only by rollers is not very satisfactory, and local uneven parts are prone to appear

In addition, when the traditional steel wheel roller is used for the initial pressing of the asphalt mixture, due to the linear contact between the steel wheel and the mixture, the contact pressure is high, and the temperature of the newly laid asphalt mixture is high and the state is loose, which often causes the mixture to push and bulge; In addition, excessive linear pressure can easily cause cracks in the asphalt mixture during the rolling process, and even break the exposed aggregate; ordinary road rollers are only suitable for flat ground operations, and cannot be used for construction on steps with height differences
