Automatic deviation-rectifying concrete road spreading and road marking machine

Abstract

The invention discloses an automatic deviation-rectifying concrete road spreading and road marking machine. The automatic deviation-rectifying concrete road spreading and road marking machine comprises a truss, a concrete hopper, a feeding pipe, a material dropping opening, mixing cage lifting control devices, vibration lifting control devices, material conveying mixing cages, vibrating devices, walking wheels, walking motors, a control box, spraying material hoppers, spraying devices, a rolling roller, a longitudinal cutting blade and a transverse cutting blade, wherein the material conveying mixing cages are connected under the mixing cage lifting control devices; and the longitudinal cutting blade and the transverse cutting blade are arranged on the circumference of the rolling roller; a rotating bearing is arranged on the feeding pipe; and the spraying devices comprise paint chambers, partition plates, adjusting plates and spraying nozzles. As the nozzles of the spraying devices are arranged on the rear side of the material dropping opening, the spraying devices spray the construction ground to draw road markings while a paver is performing road surface laying construction, and the road markings are compacted and flattened by the rolling roller and contraction joints are cut; therefore, the just laid concrete and the sprayed markings form the same plane so that the duration is long.

Description

technical field [0001] The invention relates to an automatic deviation correcting concrete road paving and road marking machine. Background technique [0002] At present, concrete road construction has the characteristics of long construction line, tight construction period, heavy tasks, and large amount of concrete pouring. During the construction process, a large number of road construction personnel are required to invest in the construction process. The construction speed is relatively slow, and the vibration and leveling are not once. It cannot be formed continuously for a long distance, and the construction quality cannot be guaranteed sometimes, especially during the road construction of long-span and wide road pavement, the concrete is directly dumped on the road surface, and then paved by road construction workers, which is not only easy to cause Concrete is unevenly spread on the road surface, and the workload is heavy. The concrete piled up for a long time is not ...

AI Technical Summary

Problems solved by technology

The joints of cement concrete pavement can be divided into two categories: longitudinal joints and transverse joints. Now the concrete pavement is mostly paved and then cut by a cutting machine, which not only affects the construction progress, is time-consuming and laborious, but also causes a lot of dust; urban roads The road surface of roads, airports and expressways generally needs to be sprayed with road middle lines and lane dividers, which are used to control, guide traffic and disperse traffic flow facilities. According to the requirements of "Marking Lines" (GB5768-2009), the current pavement construction process of road markings is to spray-paint the ground markings separately after the completion of road construction. The shape, the sprayed marking lines protrude from the road surface, causing unevenness in driving, and it is easy to fade away. It is extremely inconvenient to spray marking lines of different colors, double lines or single lines, and needs to be sprayed separately. This kind of construction period is relatively long and the cost is high.
