Description

Technical Field

[0001] This utility model relates to the technical field of road repair equipment, and in particular to an asphalt road repair device. Background Technology

[0002] Asphalt is an organic binder material. When exposed to sunlight, air, moisture, and temperature changes over a long period, it undergoes oxidative aging, becoming hard and brittle, with reduced flexibility and adhesion, and significantly weakened crack resistance. Aging pavements are more prone to developing fine, network-like cracks under temperature stress or minor loads. Furthermore, rainwater entering in winter and freezing can exacerbate crack development, further deepening pavement damage and severely impacting service life. Therefore, timely repair of asphalt pavement cracks is crucial to extend its service life. Patent CN222796162U discloses an asphalt pavement repair device that uses a leveling component to position and level extruded material. However, the repaired asphalt still needs to be compacted to prevent loose asphalt from affecting the repair effect.

[0003] Therefore, in order to address the above problems, an asphalt pavement repair device is proposed to solve them. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing an asphalt pavement repair device. This device can fill and repair asphalt cracks in the pavement while simultaneously compacting the repaired asphalt.

[0005] The technical solution of this utility model to solve the technical problem is as follows: an asphalt pavement repair device, including a mobile trolley, a mixing bucket and a discharge pipe are installed on the mobile trolley, a scraper and a pressure roller are installed below the mobile trolley, the pressure roller is located behind the scraper, and the pressure roller is connected to the mobile trolley through an adjustment structure.

[0006] The mixing drum contains fluid asphalt, which is used to fill cracks in the road surface through the discharge pipe. The asphalt is then smoothed by a scraper and pressed by a pressure roller to improve the repair effect.

[0007] Preferably, the adjustment structure includes a mounting frame located below the moving trolley, a limiting sleeve on the mounting frame, a sliding moving rod inside the limiting sleeve, a mounting frame at the lower part of the moving rod, and a pressure roller inside the mounting frame.

[0008] Preferably, the limiting sleeve is provided with limiting grooves on both sides, the limiting grooves are vertically set, the limiting bolts are slidably connected in the limiting grooves, the limiting bolts are set on the moving rod, and a compression spring is set on the outside of the moving rod. The upper end of the compression spring is connected to the mounting bracket, and the lower end of the compression spring is connected to the mounting frame.

[0009] The moving rod slides within the limiting sleeve, causing the mounting frame and pressure roller to move. The compression spring pushes the mounting frame downwards, causing the pressure roller on the mounting frame to compact the repaired asphalt.

[0010] Preferably, a connecting rod is installed below the mobile trolley, and a scraper is installed at the lower part of the connecting rod. The scraper is U-shaped, with a discharge pipe installed inside the scraper, and a baffle is installed on the scraper.

[0011] The scraper can contain the asphalt, preventing it from spreading on the road surface before fully entering the cracks, thus saving materials. At the same time, the asphalt contained by the scraper flows along the crack to the bottom, and the connecting rod drives the scraper forward to smooth the asphalt on the road surface and further scrape the asphalt into the road cracks.

[0012] Preferably, a support column is provided below the mobile trolley, and a mounting platform is provided at the bottom of the support column. A mounting groove is provided inside the mounting platform, and a grooving blade is provided inside the mounting groove. The grooving blade is connected to a motor, and the motor is located on the outside of the mounting platform.

[0013] Grooving blades are used to cut grooves in the cracks of the road surface and remove sand and debris from the cracks to facilitate subsequent asphalt repairs.

[0014] Preferably, a connecting block is horizontally installed on the mounting platform, and a limiting plate is horizontally installed on the connecting block. The limiting plate is triangular, and guide plates are vertically installed on both sides of the limiting plate. An installation column is installed below the limiting plate. The installation column is inserted into the groove opened by the grooving blade in the road surface crack, and the lower part of the installation column is wrapped with cleaning cotton.

[0015] The installation column extends deep into the crack. As the installation column moves with the moving trolley, the cleaning cotton removes the remaining sand and soil from the crack. At the same time, the sand and debris cut out by the grooving blade are moved to both sides by the guide plate to prevent them from re-entering the crack.

[0016] Preferably, a vacuum cleaner is installed on the mobile cart, with the vacuum cleaner's suction pipe connected to the suction nozzle, which is located between the slotted blade and the scraper. The suction nozzle is mounted on a positioning frame, which is located below the mobile cart.

[0017] The vacuum cleaner removes the sand and debris that have been excavated, preventing contamination of the filled asphalt and ensuring a better repair result.

[0018] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0019] The mixing drum contains fluid asphalt, which is used to fill cracks in the road surface through the discharge pipe. The asphalt is then smoothed by a scraper and rolled by a pressure roller to improve the repair effect.

[0020] The moving rod slides within the limiting sleeve, causing the mounting frame and pressure roller to move. The compression spring pushes the mounting frame downwards, causing the pressure roller on the mounting frame to compact the repaired asphalt.

[0021] The scraper can contain the asphalt, preventing it from spreading on the road surface before fully entering the cracks, thus saving materials.

[0029] like Figures 1 to 4 As shown, an asphalt pavement repair device includes a mobile trolley 1, a mixing tank 2 and a discharge pipe 3 mounted on the mobile trolley 1, a scraper 4 and a pressure roller 5 mounted below the mobile trolley 1, with the pressure roller 5 located behind the scraper 4 and connected to the mobile trolley 1 via an adjusting structure. The mixing tank 2 contains fluid asphalt, which fills cracks in the pavement through the discharge pipe 3. The scraper 4 smooths the asphalt, and the pressure roller 5 compacts it, improving the repair effect.

[0030] The adjustment structure includes a mounting frame 6, which is located below the moving trolley 1. A limiting sleeve 7 is provided on the mounting frame 6, and a moving rod 8 is slidably connected inside the limiting sleeve 7. A mounting frame 9 is provided at the lower part of the moving rod 8, and a pressure roller 5 is provided inside the mounting frame 9.

[0031] Limiting grooves 10 are provided on both sides of the limiting sleeve 7. The limiting grooves 10 are vertically arranged, and limiting bolts 11 are slidably connected in the limiting grooves 10. The limiting bolts 11 are set on the moving rod 8. A compression spring 12 is set on the outside of the moving rod 8. The upper end of the compression spring 12 is connected to the mounting frame 6, and the lower end of the compression spring 12 is connected to the mounting frame 9. The moving rod 8 slides in the limiting sleeve 7, driving the mounting frame 9 and the pressure roller 5 to move. The compression spring 12 pushes the mounting frame 9 downward to move, so that the pressure roller 5 on the mounting frame 9 rolls and compacts the repaired asphalt.

[0032] A connecting rod 13 is installed below the mobile trolley 1, and a scraper 4 is installed at the lower part of the connecting rod 13. The scraper 4 is U-shaped, and a discharge pipe 3 is installed inside the scraper 4. A baffle 14 is installed on the scraper 4. The scraper 4 can contain the asphalt, preventing it from spreading on the road surface without completely entering the cracks, thus saving materials. At the same time, the asphalt contained by the scraper 4 flows into the bottom of the cracks. The connecting rod 13 drives the scraper 4 to move forward, smoothing the asphalt on the road surface and further scraping the asphalt into the road cracks.

[0033] A support column 15 is installed below the mobile trolley 1, and a mounting platform 16 is installed below the support column 15. A mounting groove 17 is provided inside the mounting platform 16, and a grooving blade 18 is installed inside the mounting groove 17. The grooving blade 18 is connected to a motor 19, which is located on the outside of the mounting platform 16. The grooving blade 18 is used to groove the cracks in the road surface and remove sand and debris from the cracks, facilitating subsequent asphalt repair.

[0034] A connecting block 24 is horizontally mounted on the mounting platform 16, and a limiting plate 25 is horizontally mounted on the connecting block 24. The limiting plate 25 is triangular, and guide plates 26 are vertically mounted on both sides of the limiting plate 25. A mounting post 27 is mounted below the limiting plate 25. The mounting post 27 extends into the groove cut by the grooving blade 18 in the road surface crack, and the lower part of the mounting post 27 is wrapped with cleaning cotton 28. As the mounting post 27 extends into the crack, it carries away the residual sand and soil from the crack through the cleaning cotton 28 while moving with the moving trolley 1. At the same time, the sand and debris cut out by the grooving blade 18 are moved to both sides by the guide plates 26 to prevent them from re-entering the crack.

[0035] A vacuum cleaner 20 is installed on the mobile trolley 1. The suction pipe 21 of the vacuum cleaner 20 is connected to a suction nozzle 22, which is located between the grooving blade 18 and the scraper 4. The suction nozzle 22 is mounted on a positioning frame 23, which is located below the mobile trolley 1. The vacuum cleaner 20 removes the excavated sand and debris to prevent contamination of the filled asphalt and to avoid affecting the repair effect.

[0036] Working principle: The moving trolley 1 moves forward along the crack direction. The grooving blade 18 cuts and widens the original crack to form a regular groove. At the same time, it removes loose and aged asphalt, sand, debris and other materials from the crack. The suction nozzle 22 is aligned with the newly opened groove, and the vacuum cleaner 20 starts to generate negative pressure, instantly sucking in and collecting the sand, debris and other materials removed during the grooving process. The discharge pipe 3 located inside the scraper 4 is aligned with the cleaned crack groove and injects the repair asphalt. At the same time, the asphalt is scraped flat. Under the action of the compression spring 12, the mounting frame 9 drives the pressure roller 5 to continuously apply downward pressure. The pressure roller 5 rolls and crushes the repair area to enhance the adhesion between the asphalt and the crack groove wall.

[0037] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
