Description

Technical Field

[0001] The present invention relates to the technical field of road surface repair, and in particular to a paved road surface repair device and method thereof. Background Art

[0002] Pavement repair technology is a crucial maintenance tool for urban roads, airport runways, and parking lots. Existing technologies primarily include manual repair and semi-automated equipment. Manual repair involves filling cracks with asphalt or cold patch material using hand tools. This method is simple to use, inexpensive, and suitable for small-scale repairs. Semi-automated equipment uses storage devices and delivery pipelines to fill material. Some equipment is equipped with heating devices to maintain the fluidity of repair materials (such as asphalt) and improve construction efficiency. These devices typically utilize simple mechanical structures, capable of completing crack filling tasks within a certain range, and are widely used in municipal road maintenance. Some advanced equipment also incorporates basic scanning devices for preliminary crack shape identification to assist in repair operations, providing a convenient solution for road maintenance.

[0003] However, existing technologies have significant shortcomings. Manual repair is inefficient and has poor precision. The quality of repair is greatly affected by the operator's technical level, and it is difficult to deal with complex cracks. Although semi-automated equipment has improved efficiency, the crack scanning accuracy is limited and the path planning ability is insufficient, resulting in uneven material filling and poor repair effects. Existing heating systems usually only cover the storage part, and the material is prone to cooling during transportation, affecting fluidity. In addition, the equipment has a low degree of intelligence and is difficult to adapt to various crack types and construction environments. The road surface is not smooth and dense after repair, and manual secondary processing is often required, which increases maintenance costs and time. Summary of the Invention

[0010] Preferably, the CNC mechanism includes a box body, a CNC computer is fixed on the top of the box body, a power supply component is fixed inside the box body, and a charging port, a power indicator light and a power switch are provided on one side of the box body.

[0011] A method for repairing a paved road surface using a paved road surface repair device comprises the following steps: S1. Start the scanning mechanism, move the scanning head along the first linear slide, identify cracks and scan the contours of the paved road surface, and generate crack path data; S2.

[0016] 2. The device's discharge mechanism is combined with a temperature control mechanism to ensure constant temperature delivery of the repair material, significantly improving material flow and repair effectiveness. The heating plate on the inner wall of the storage box and the hot air circulation system of the temperature control mechanism simultaneously heat the storage box and screw conveyor, maintaining the appropriate temperature of materials such as asphalt and preventing cooling and solidification during transportation. The design of the flexible conduit and discharge pipe ensures that the material is delivered precisely to the crack location, reducing spillage and waste. Compared to existing equipment that only heats the storage material, this device maintains a constant temperature throughout the entire transportation process, ensuring the uniformity and adhesion of the repair material, thereby improving the durability and service life of the repaired pavement.

[0017] 3. The device uses manually operated rollers to perform post-repair compaction and leveling, effectively improving the flatness and density of the repaired road surface. Claim 10 clearly states that after the cracks are filled in the discharge pipe, the filler is compacted by manual rollers. Compared with fully automated leveling, manual operation is more flexible and can adjust the force and method according to the actual situation of the cracks to ensure that the filler is tightly combined with the road surface. This design combines the advantages of automated filling and manual finishing, retaining the high efficiency of the equipment while improving the repair quality through manual intervention. It is suitable for a variety of road conditions, reduces secondary rework, and enhances the long-term stability of the repaired road surface. BRIEF DESCRIPTION OF THE DRAWINGS

In step S4, the clamp 304 is controlled to move continuously along the crack path to complete accurate filling and efficient repair. This method significantly improves the repair accuracy and efficiency through automated scanning, path planning, and material filling, and is suitable for road maintenance scenarios with complex cracks.

[0035] In the present invention, in step S1 , the scanning head 202 is disposed between the two first linear slides 201 , and its scanning direction is perpendicular to the road surface, so as to improve the crack recognition accuracy.

[0036] In this embodiment, the scanning head 202 is positioned between the two first linear slides 201. The relative movement of the first linear slides 201 enables stable horizontal scanning. Its scanning unit is oriented vertically toward the road surface, ensuring direct alignment with the crack for contour scanning, thereby generating highly accurate crack path data.

[0038] In this embodiment, the discharge mechanism 4 utilizes heating plates on the inner wall of the storage box 401 and the hot air circulation system of the temperature control mechanism 5 to simultaneously heat the storage box 401 and the screw conveyor 402 at a constant temperature. This ensures that the repair material (such as asphalt) maintains a suitable temperature during storage and transportation, preventing it from cooling and solidifying. This design significantly improves the fluidity of the material. Compared to traditional equipment that only heats the stored material, it reduces material blockage and waste during transportation, ensures uniform filling, and improves repair quality. It is suitable for complex road repair scenarios requiring high-temperature materials.

[0039] In the present invention, after the discharging pipe 404 fills the crack with the repair material, the filling material is compacted and leveled by manually operating a pressure roller to improve the flatness and density of the repaired road surface.

[0040] In this embodiment, after the repair material is filled into the crack by discharge pipe 404, manually operated rollers are used to compact and level the filler, ensuring a tight bond between the material and the road surface. This manual intervention method flexibly adapts to different crack shapes and construction conditions. Compared to fully automated leveling, it can adjust the force according to actual conditions, improving the smoothness and density of the repaired road surface. Compared to traditional repair methods, this step effectively reduces the problem of loose or uneven filler, enhances the durability and service life of the repaired road surface, and is suitable for diverse road maintenance scenarios, such as urban roads.
