Pavement comprehensive maintenance vehicle

Abstract

The invention discloses a pavement comprehensive maintenance vehicle. The pavement comprehensive maintenance vehicle comprises a vehicle chassis, a material mixing bin and an asphalt box, wherein thematerial mixing bin and the asphalt box are arranged on the vehicle chassis, and an asphalt conveying pipeline are arranged between the material mixing bin and the asphalt box; the material mixing bincomprises a front cabin body and a rear cabin body, wherein the front cabin body and the rear cabin body are arranged on the vehicle chassis, one side of each bin cover is provided with a corresponding material receiving groove, and discharging ports of the front cabin body and the rear cabin body both communicate with an upper port of a hopper; the asphalt box is internally provided with a metering box, wherein the lower part of the metering box is connected with an asphalt conveying pipeline, the asphalt conveying pipeline is introduced towards the rear cabin body through a port of a three-way joint and towards the front cabin body through the other port of the three-way joint; and an asphalt output pump is connected with an asphalt gun motor fixedly arranged on the outer side of the asphalt box through an output shaft. The pavement comprehensive maintenance vehicle has complete asphalt pavement disease treatment function, namely, pit slots, cracks, ruts and other diseases can be treated through the asphalt output pump and the asphalt gun, on-site production of new asphalt mixture, asphalt pavement on-site heat regeneration, asphalt distributing, crack filling and sealing and other functions can be achieved.

Description

technical field [0001] The invention belongs to the technical field of road maintenance equipment, and in particular relates to a comprehensive road surface maintenance vehicle. Background technique [0002] With the rapid development of highway transportation, the workload of road repairs has also increased rapidly. Most of the existing road maintenance equipment is refitted with automobile chassis. Fill and repair road damage such as potholes, cracks, and depressions. If the repaired pits are small, use a large mixing bin to stir and heat the asphalt mixture, and the fuel utilization rate is relatively low; if the repaired potholes are large , the asphalt material in a mixing silo may not be enough, and new aggregate or hot asphalt needs to be continuously added, and the work efficiency is low; in addition, the waste asphalt material from the excavation of the pit needs to be crushed, and the processing process is cumbersome, eliminating old asphalt Materials will also po...
