Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to an integrated device for repairing and reinforcing road surface cracks. Background Technology

[0002] Road maintenance refers to a series of tasks involving the upkeep, maintenance, improvement, and repair of transportation infrastructure such as highways and urban roads. The aim is to improve road performance, service levels, and safety, ensuring unimpeded traffic flow and extending service life. This includes categories such as routine maintenance (e.g., sweeping, crack filling), minor repairs (partial repairs), medium repairs (major overhauls), and major repairs or reconstructions (large-scale upgrades). It involves comprehensive management of pavement, shoulders, drainage, bridges, culverts, and roadside facilities. Traditional pavement crack repair and reinforcement requires first using a road grooving machine to create grooves in the cracks, then using a blower to remove impurities from the groove, followed by heating and drying the groove with a hot air gun, and finally using a crack filling machine to melt asphalt and evenly pour it into the groove and smooth it out. Traditional pavement crack repair and reinforcement requires sequential steps of grooving, impurity removal, drying, and crack filling, resulting in low efficiency and long time intervals between each step. Furthermore, outdoor work means that after the groove is dried, impurities on the road surface can easily be blown back into the groove by the wind, affecting subsequent crack filling work. Therefore, we propose an integrated pavement crack repair and reinforcement device. Utility Model Content

[0027] The repair vehicle 1 has a support wheel 10 rotatably connected to the lower middle of its interior. Both the left and right ends of the rear side of the repair vehicle 1 are equipped with casters 11. The casters 11 are polyurethane casters with brakes, which are common in the prior art. A bevel gear 12 is fixedly sleeved on the middle of the outer surface of the support wheel 10. A bevel gear 2 13 is provided on the rear side of the turntable 51. The bevel gear 12 and the bevel gear 2 13 are meshed and connected to provide a transmission effect for the left and right swing of the blow nozzle 3.

[0028] The working principle of the integrated road crack repair and reinforcement device provided by this utility model is as follows: When repairing and reinforcing road cracks, an external grooving machine is first used to groove the cracks in the road surface. Then, the operator pours the repair material, such as asphalt, into the asphalt hot melt tank 2. The gasoline fuel in the fuel tank 15 is sent into the generator 14. The generator 14 generates electrical energy to drive the controller 16. The controller 16 controls the heating tube 9 to work. The heating tube 9 emits heat to heat the heat transfer oil inside the jacket. Through heat transfer from the inner wall of the asphalt hot melt tank 2, the repair material inside the asphalt hot melt tank 2 is heated and melted. The handwheel 7 can be turned to drive the mixing frame 6 to rotate, creating a stirring effect on the repair material inside the asphalt hot melt tank 2, so that the repair material is heated and melted more thoroughly. At the same time, the controller 16 controls the operation of cameras 57 and 58. Camera 57 captures images of the road conditions in front of the repair vehicle 1 to determine the approximate location of the road surface cracks, while camera 58 captures the specific location of the cracks for precise crack repair. After capturing images, cameras 57 and 58 generate image data through image sensors and send it to the controller 16, which then projects it onto the screen on the controller 16 surface, allowing operators to precisely move the repair vehicle 1. When the crack repair material is heated to a completely melted state, it can be determined whether the material has reached a completely melted state by opening the feeding cover 8 or rotating the mixing rack 6 to feel the resistance. The controller 16 controls the blower 553 to operate, which draws in and accelerates external air, passing it through a hose. The air is fed into the nozzle 3. Simultaneously, the controller 16 controls the heating wire 551 to operate. The heating wire 551 dissipates heat, and the air entering the nozzle 3 is heated by the heating wire 551. When passing through the baffle 552, the air is blocked by the baffle 552, creating a vortex inside the nozzle 3, allowing the heating wire 551 to heat the air more evenly. The heated air is then blown out at high speed from the flat nozzle 3, hitting the inside of the trough on the road surface. This blows out impurities from the trough while simultaneously heating and drying the inner wall of the trough. At this time, the operator pushes the repair vehicle 1 forward, causing the support wheel 10 and the caster wheel 11 to rotate. As the support wheel 10 rotates, the first bevel gear 12 also rotates, driving the second bevel gear 13 and the turntable 51 to rotate. The limit post... 52 also rotates, squeezing the inner wall of the limiting frame 53, causing the limiting frame 53 to move back and forth. At the same time, the front side of the limiting frame 53 moves the rear side of the connecting frame 54, causing the connecting frame 54 and the spray head 3 to swing left and right. This increases the spraying range of the spray head 3, facilitating the rapid and thorough removal of impurities inside the tank. The high-temperature hot air also dries the inner wall of the tank. After the tank is cleaned, turning the knob 563 drives the screw 562 to rotate, and the scraper 561 moves down accordingly. The thickness of the joint filler material can be adjusted by adjusting the distance between the lower end of the scraper 561 and the ground. The greater the distance between the lower end of the scraper 561 and the ground, the thicker the joint filler material, and vice versa. After adjusting the height of the scraper 561, the controller 16 controls the asphalt pump 564 to work.Asphalt pump 564 pumps the molten joint filler material evenly downwards. Combined with images captured by camera 58, the molten material is precisely poured into the tank. Then, scraper 561 smooths out any excess material while applying pressure to the joint, improving the stability of the filler material. The entire process integrates impurity removal, drying, and filling, reducing time intervals between steps and improving both the efficiency and quality of road joint repair.

[0029] It is worth noting that the controller 16 disclosed in the above embodiments can be an STM8S003F3P6 controller, the generator 14 can be a YT8000DCE-2 generator, the blower 553 can be an RB-71D-3 blower, the asphalt pump 564 can be an LCB-3A asphalt pump, and both camera 1 57 and camera 2 58 can be YLX-F0815 cameras. The controller 16 controls the operation of the generator 14, heating tube 9, heating wire 551, blower 553, asphalt pump 564, camera 1 57 and camera 2 58 using methods commonly used in the prior art.
