Multifunctional highway maintenance vehicle capable of automatically conveying material

Abstract

The invention relates to a multifunctional highway maintenance vehicle capable of automatically conveying a material. The multifunctional highway maintenance vehicle comprises a chassis, which is provided with a waste conveying groove, a mixed material conveying groove, a balance rotation table and a control system, wherein the balance rotation table is connected to a tool centralization platformthrough a joint mechanical arm, a pressing mechanism is arranged below the balance rotation table, a waste feeding mechanism is arranged in a waste feeding groove, the waste feeding groove is communicated to a heating stirring cylinder through a waste crushing cylinder, the inner cavity of the waste crushing cylinder is provided with a waste crushing mechanism, the waste crushing cylinder is provided with a material discharge control mechanism, the heating stirring cylinder is provided with a mixed material discharge control hydraulic cylinder, and the inner cavity of the heating stirring cylinder is provided with a heating assembly and a stirring mechanism. According to the present invention, the multifunctional highway maintenance vehicle can be used for the maintenance of the common problems such as small cracks and small-area diseases pot holes on highway, is suitable for the early-stage road surface disease maintenance, and has advantages of precise positioning, flexible repair, light structure, high work efficiency, high intelligence, less manual work, manpower saving and high maintenance targeting property.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement maintenance equipment research, and in particular relates to a multifunctional road maintenance vehicle with a joint mechanical arm and an automatic feeding device. Background technique [0002] With the construction of a large number of urban, rural and mountainous roads in my country, the mileage of roads in my country has leapt to the second in the world, and the climax of road construction is coming to an end. With the increase in the number of years of roads that have been built, a large number of roads will soon enter maintenance stage. However, my country's emphasis on road maintenance and the development of road maintenance equipment lag behind foreign countries. At present, the existing road maintenance vehicles in China mainly have the following problems: [0003] (1) During the maintenance process of the road maintenance vehicle, it is necessary to use special lifting equipment...

AI Technical Summary

Problems solved by technology

[0003] (1) During the maintenance process of the road maintenance vehicle, it is necessary to use special lifting equipment to hoist compaction equipment, road milling equipment, cutting equipment, joint filling equipment, etc. to the vehicle to fix and under the vehicle for construction. The quality of the equipment is often large (for example, the mass of many compaction equipment exceeds 300kg), so a generator set with a higher power must be selected to provide power for lifting. Larger car chassis, the comprehensive consequences of these factors not only increase the cost of road maintenance vehicles, but also have safety hazards in the lifting process of maintenance equipment, and increase the physical exertion of maintenance construction workers

[0004] (2) Low degree of automation

At present, the maintenance equipment of road maintenance vehicles requires workers to directly operate during the maintenance process. These equipments are of high quality, have large vibrations during construction, and there is a lot of dust during cutting and crushing, which will cause great damage to the workers. The degree of automatic control of maintenance equipment is low, and there is no Realize automatic control of maintenance equipment

[0005] (3) The degree of rational optimization of power between maintenance equipment is low

At present, many road maintenance vehicles are equipped with cutting machines, milling machines and other maintenance equipment on the general-purpose automobile chassis, and each equipment is powered by an independent diesel engine. Although it is convenient to use, the overall power is not optimized, so resources are seriously wasted.

[0006] (4) At present, the maintenance of road maintenance vehicles is poorly targeted, and many road maintenance vehicles are "full-function but not specialized", so the efficiency of maintenance for specific road damage is poor

[0007] (5) The efficiency of the mixture heating device is low, and the heating preparation time is long
