A truss-type concrete road construction and road marking spraying machine

Abstract

The invention discloses a truss type concrete road construction and road marking spraying integrated machine. The truss type concrete road construction and road marking spraying integrated 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 and a rolling roller, wherein the material conveying mixing cages are connected under the mixing cage lifting control devices; the rolling roller is connected to the truss; 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 so that the just laid concrete and the sprayed markings form the same plane, therefore, the duration is long. The feeding pipe and a branch pipe are driven to rotate in the concrete hopper by the rotating bearing so that the concrete is uniformly mixed.

Description

technical field [0001] The invention relates to a truss-type concrete road construction and road marking integrated spraying 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.

[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. Concrete piled up for a long time is not easy to vibrate and compact, which affects the construction quality of the entire road surface

The existing concrete paving and vibrating equipment can only pave and vibrate in one direction, that is, one-way operation, the construction speed is slow, and there are easy dead angles at the edge of paving and vibrating, and manual paving is required in the follow-up Paving, vibrating, and leveling are labor-intensive and affect the construction quality; the road surfaces of urban roads, airports, and expressways generally need to be sprayed with road middle lines and lane dividers, which are used to control, guide traffic, and disperse traffic flow. The width, dotted line and distance of the marking line, the length of the dotted line, etc. should meet the requirements of the "Road Traffic Marking Lines" (GB5768-2009). The current paving construction process of the road marking line is to carry out the ground marking separately after the road construction is completed. Line spraying, before spraying, it is necessary to establish the baseline first, and then delineate the shape of the marking line. The sprayed marking line protrudes from the road surface, causing a bumpy feeling on the road, and it is easy to fade away. For marking lines of different colors, double lines or single lines The spraying is extremely inconvenient and needs to be sprayed separately. This kind of construction period is relatively long and the cost is high
