Flattening device for road pavement concrete

Abstract

The invention discloses a flattening device for road pavement concrete. The flattening device comprises a flattening plate, a bottom plate, a baffle, a motor shell, a vibration pump, a handrail, a control panel, a transverse rod, a pedal, supporting rods, a base plate, a pushing tip, transmission rods and a rubber pad. The transmission rod is respectively arranged at two ends of the flattening plate; the bottom plate is supported on the transmission rods, the vibration pump mounted on bottom plate; the vibration pump is not in direct contact with the flattening plate, instead, vibration is transmitted to the flattening plate through the two transmission rods; therefore, the pressure of the flattening plate on the road surface is uniform when the concrete road surface is flattened, the flattening effect can be improved, two ends of the flattening plate can be prevented from tilting after being used for a long time to influence the flattening of concrete, the working efficiency is improved, and the supporting rods are arranged at two ends of the motor shell and can rotate to flatten a curve part through the supporting rods. The flattening device has the characteristics that the flattening effect is enhanced, and the curve road surface can be flattened conveniently.

Description

technical field [0001] The invention relates to a smoothing device, in particular to a smoothing device for road laying concrete. Background technique [0002] Road bridges are generally composed of several parts such as roadbed, road surface, bridge, tunnel engineering and traffic engineering facilities. When laying roads, it is necessary to lay concrete on the road surface first, and then use a vibrating ruler to smooth the newly laid concrete. In the subsequent work of laying cement, if the concrete is uneven, cracks will appear on the cement laid on the surface, and the bearing capacity will not be good. [0003] However, there are still certain defects in the existing concrete during grinding. Although the existing grinding device can grind the concrete, but because the vibration pump directly acts on the center of the pressing plate, the midpoint of the pressing plate is vibrated for a long time. , will cause the two ends of the pressing plate to lift, so that the gri...

Problems solved by technology

[0002] Road bridges are generally composed of subgrades, road surfaces, bridges, tunnel engineering and traffic engineering facilities. When laying roads, it is necessary to lay concrete on the road surface first, and then use a vibrating ruler to smooth the newly laid concrete. After laying cement work, if the concrete is uneven, the cement laid on the surface will crack and the bearing capacity will not be good

[0003] However, there are still certain defects in the existing concrete during grinding. Although the existing grinding device can grind the concrete, but because the vibration pump directly acts on the center of the pressing plate, the midpoint of the pressing plate is vibrated for a long time. , will cause the two ends of the pressing plate to be lifted, so that the grinding effect of the two ends will decrease, and the center vibration will make the pressure of the pressing plate on the concrete pavement uneven, and the grinding effect will not be very good. If there is a bend, the grinding device Bulky and inconvenient for smoothing concrete at bends
