In order to make those skilled in the art understand the technical solution, the following detailed description is made on a high-perception repairing device for repairing a damaged asphalt pavement according to the present invention with reference to the specific embodiments and the accompanying drawings.
As shown in figures 1-4, a high-perception repairing device for repairing damaged asphalt pavement comprises a rectangular frame 2 with a push handle 1, a guiding and cleaning device 3 which is arranged in front of the frame and used for cleaning chips around the damaged asphalt pavement, a moving device which is arranged at the bottom of the frame and used for moving the frame at the edge of the damaged asphalt pavement, a cutting device 4 which is arranged at the rear side of the frame and used for removing broken aggregates of the damaged asphalt pavement, a driving device which is arranged in the frame and used for providing power for the cutting device, and a heating device 5 which is arranged at the bottom of the frame and used for heating the damaged asphalt pavement, wherein the heating device is arranged at the front side of the cutting device, comprises an infrared heater 51 which is arranged at the outer side of the bottom of a shell and is divided according to a heat transfer mode, and the heating mode for the asphalt pavement comprises radiation, Convection can only exchange heat from a heat source to the asphalt surface, and heating of deep asphalt must be by conduction or radiation. Because asphalt concrete is a poor thermal conductor, the heat conduction speed is very low, and the requirement of rapid heating cannot be met by conduction, therefore, the on-site thermal regeneration of the asphalt pavement is necessarily mainly achieved by radiation, and other heating modes are assisted. The infrared ray has a wavelength range of 0.76 to 1000 μm, but a wavelength range of 2 to 5 μm is suitable for use according to the characteristics of the asphalt concrete, in which the infrared ray absorption rate of the asphalt concrete exceeds 90%. The penetration depth of infrared rays to asphalt concrete is 5-6cm, and beyond this depth, infrared heating is difficult. As the field thermal regeneration is generally used for repairing surface layer diseases, the requirement of heating by using infrared rays can be met.
