Thermal-insulation storage type bituminous pavement comprehensive maintenance vehicle

Abstract

The invention discloses a thermal-insulation storage type bituminous pavement comprehensive maintenance vehicle which is characterized in that the vehicle comprises an automotive chassis, a vehicle frame, a thermal-insulation bunker, a heating system, a generator set, a heating wall system, an emulsified asphalt system, an auxiliary tool, an upper enclosure and a lower vehicle fence. As for electrical heating, the generator set can output electric energy or mains supply as two modes of heating. The thermal-insulation bunker is provided with an anti-caking device capable of realizing positive and negative rotating and stirring and preventing a bituminous mixture from being cooled, arched and separated, and a spiral feeder assists to discharge materials. Discharge of materials is continuous, fast and free of blocking materials. The vehicle of the invention has two disease repairing technologies. Different repairing technologies can be selected according to the disease degree of the pavement. The vehicle of the invention has strong adaptability, high repairing efficiency and good repairing quality. The vehicle of the invention adopts a double-heat-source series circulatory heating mode and has three selection modes, namely diesel oil heating, electrical heating by the generator set and mains supply heating. The vehicle is energy-saving and efficient and has strong adaptability. By the use of the vehicle, the problem that a single heat source used for heating causes abnormity and construction failure is solved.

Description

technical field [0001] The invention relates to an asphalt pavement comprehensive maintenance vehicle, in particular to a thermal insulation storage type asphalt pavement comprehensive maintenance vehicle. Background technique [0002] Various diseases such as potholes, cracks, wrapping, pockmarks, etc. often occur in the use of asphalt pavement. The asphalt pavement comprehensive maintenance vehicle is a kind of maintenance equipment specially used to deal with the above diseases. Among them, the thermal insulation storage type asphalt pavement comprehensive maintenance Cars are one of them. The existing thermal insulation storage type asphalt pavement comprehensive maintenance vehicles have the following disadvantages: 1. The function is not complete, and the repair process is single, and it is impossible to select a differentiated repair process according to the degree of disease on the asphalt pavement; 2. There are many thermal insulation silos Using liquefied petroleu...

AI Technical Summary

Problems solved by technology

The whole machine is multi-functional and integrated, and has two disease repair processes: cold cutting and hot repairing and in-situ hot regeneration. The cold cutting and hot repairing process is: road surface cutting - road surface crushing - pit cleaning - pit heating - asphalt spraying ——Filling thermal material——Pavement compaction——Waste recycling, in-situ thermal regeneration process is: road surface heating——Road surface raking—(Cleaning surface waste)——Asphalt spraying——Filling thermal material——Pavement compaction— —Waste recycling, suitable repairing process can be selected according to the degree of road surface disease, with stronger adaptability, high repairing efficiency and good repairing quality; adopts diesel burner heating heat conduction oil fire tube and electric heating heat conduction oil tank dual heat source series circulation heating method Among them, electric heating can choose two heating methods: generator output electric energy or mains electricity, and has three options of diesel heating, generator electric heating and mains heating, energy saving and high efficiency, strong adaptability, and solves the problem that single heat source heating is abnormal and cannot be constructed Difficulties: S-shaped arrangement of elliptical heat-conducting oil coils is adopted, the pipe wall is in surface contact with the silo wall, the heat exchange area is large, and the sealing is good, which solves the low heating efficiency of the circular heat-conducting oil pipe and the silo wall. The silo wall is lined with heat-conducting oil tanks and the heat-conducting oil is easy to leak; the anti-caking device is used for real-time forward and reverse stirring, which can effectively prevent the asphalt mixture from arching and segregation when it is cooled, and assist in stirring and discharging, and the discharge is continuous and fast without material jams ;Adopt variable-pitch helical balanced continuous material conveying in different areas, and the discharge guide groove at the tail can realize 180° rotation, control the direction and position of asphalt material conveying, high construction efficiency, save time and effort, and effectively reduce the labor intensity of workers
