Description

Technical Field

[0001] The present invention belongs to the technical field of highway inspection, and in particular to an intelligent inspection and maintenance system for an asphalt highway pavement. Background Art

[0002] Asphalt pavement is a modern road structure constructed from an asphalt mixture. Its core material is asphalt concrete, a mixture of petroleum-derived asphalt and mineral aggregates of varying particle sizes (such as gravel, sand, and mineral powder) mixed at high temperatures. During construction, the mixture is first heated to 150-180°C to maintain fluidity. It is then evenly poured onto a compacted roadbed using a specialized paver. The pavement then undergoes three stages of compaction: initial, secondary, and final compaction, achieving the desired density and smoothness.

[0003] Currently, asphalt roads are generally prone to road surface defects such as cracks and potholes during long-term use, which require manual inspections to detect and maintain them in a timely manner.

[0004] However, traditional manual inspections have numerous limitations. First, they require maintenance personnel to frequently conduct road inspections, resulting in low efficiency and potential safety hazards. Second, in challenging climates (such as dusty deserts, high-altitude mountainous areas, or areas with strong winds), manual inspections become significantly more difficult and risky. These areas often experience low visibility and poor traffic conditions, which not only increases the workload for inspectors but also significantly impacts the timely detection and treatment of road surface defects.

The driving wheel 5 can rotate universally to control the entire device to inspect the asphalt road surface. During the inspection process, when the monitor 3 captures potholes and cracks on the road surface, the asphalt bin 1 can be moved above the potholes and cracks, and then the connecting plate 8 is moved downward with the help of the moving mechanism. At this time, the connecting plate 8 will cover the potholes and cracks, and then the control valve 9 is opened to allow the asphalt in the asphalt bin 1 to be discharged from the discharge pipe 6 and then injected into the potholes and cracks through the regulating pipe 7. Due to the coverage of the potholes and cracks by the connecting plate 8, the asphalt can be evenly filled into the potholes and cracks to maintain the asphalt road surface. The above-mentioned mechanism can be used to intelligently inspect the asphalt road surface, and automatically perform maintenance when potholes and cracks are found. It can be adapted to use in a variety of special environmental areas. Asphalt is stored in the asphalt bin 1, and a heating rod and stirring blades can be set in the asphalt bin 1 to stir the asphalt to prevent solidification.

[0023] The movable mechanism includes a fixed plate 10 fixedly connected to the bottom surface of the asphalt bin 1, and the fixed plate 10 is rotatably connected to a connecting shaft 12 on one side near the discharge pipe 6, and a take-up wheel 13 is fixedly connected to the surface of the take-up wheel 13, and a connecting line 14 is fixedly connected to the bottom end of the connecting line 14 is fixedly connected to the connecting plate 8.

[0024] A rectangular plate 16 is slidably connected to one side of the asphalt bin 1, and a group of bristles 17 are fixedly connected to the bottom surface of the rectangular plate 16; in the present application, when repairing potholes and cracks, the connecting plate 8 can be moved downward first, but the connecting plate 8 does not contact the ground. At this time, the bristles 17 will contact the ground, and then the entire device is moved so that the bristles 17 pass through the potholes and cracks, thereby cleaning out impurities such as gravel in the potholes and cracks, preventing these impurities from affecting the asphalt repair effect on potholes and cracks.

[0025] The connecting plate 8 is provided with a first cavity 18 and a second cavity 19. The bottom surface of the connecting plate 8 is provided with a plurality of air suction holes 20 connected to the first cavity 18.

When the bristles 17 of the present application are cleaning potholes and cracks, the gas in the first cavity 18 can be sucked out by the air source component. At this time, the elastic sheet 25 will be deformed by the suction force, so that the shrinkage hole opens. At this time, the suction hole 20 can suck away the dust in the potholes and cracks to further improve the repair effect of asphalt on potholes and cracks. When the suction stops, the shrinkage hole of the elastic sheet 25 will close. At this time, the dust will be stored in the first cavity 18. The air source component can also inject air into the second cavity 19, so that the gas is blown into the potholes and cracks from the air outlet 21, thereby drying the moisture in the potholes and cracks to prevent water in the potholes and cracks from affecting the use of asphalt.

During the rotation process, the connecting line 14 will not pull the connecting plate 8 up. When the connecting shaft 12 rotates, the driving rod will push the driving block 28, so that the driving block 28 drives the connecting ring 27 to squeeze the elastic ring 26. At this time, the gas in the elastic ring 26 can enter the second cavity 19 from the air outlet pipe 23, and then be blown out from the air outlet 21 to dry the moisture in the potholes and cracks. After the driving rod passes over the driving block 28, the elastic ring 26 will recover due to its own elasticity. At this time, the gas in the first cavity 18 will be sucked in, so that the suction hole 20 generates suction, thereby sucking away the dust in the potholes and cracks, so as to improve the asphalt repair effect on potholes and cracks.
