Abstract
Description
Technical Field
[0001] This utility model relates to an asphalt concrete pavement crack repair device, belonging to the technical field of pavement crack repair devices. Background Technology
[0002] Road surface cracks are a common problem in road maintenance. They are mainly divided into load-related cracks and non-load-related cracks. Load-related cracks are caused by the tensile stress under traffic loads exceeding the tensile strength of the base material. Common forms include transverse cracks and longitudinal cracks. Non-load-related cracks are mainly caused by temperature changes, such as low-temperature shrinkage cracks and temperature fatigue cracks.
[0003] When cracks appear on the road surface, they need to be repaired to ensure the normal use and service life of the road. In actual operation, workers place asphalt inside the housing of the road crack repair device and then push the device to make the asphalt fall into the crack for repair. However, existing road crack repair devices cannot clean the dirt in the crack, so workers need to clean it with tools beforehand. Moreover, if asphalt remains inside the housing after one crack is repaired, it is inconvenient to move the asphalt to another crack, which may result in material waste. Utility Model Content
[0004] The purpose of this invention is to provide a device for repairing cracks in asphalt concrete pavement. This invention can facilitate the cleaning of debris in cracks, reduce the labor intensity of workers, and avoid material waste, thereby effectively improving the practicality of the device and solving the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please refer to Example 1 Figures 1-4 This utility model provides a technical solution:
[0023] A device for repairing cracks in asphalt concrete pavement includes a repair shell 1. A support rod 2 is fixedly mounted on one side of the repair shell 1. A battery box 3 is connected to the top of the support rod 2. A second support rod 4 is connected to the top of the battery box 3. Fixing seats 5 are fixedly mounted on both the front and rear sides of the repair shell 1. A cylinder 6 is fixedly embedded in each fixing seat 5. The output end of each cylinder 6 extends outside the fixing seat 5 and is fixedly connected to a fixing plate 7. A scraper 8 matching the repair shell 1 is fixedly mounted on the lower part of the fixing plate 7 near the repair shell 1. A second fixing seat 9 is fixedly mounted on the side of the repair shell 1 away from the support rod 2. A blower 10 is fixedly embedded in the second fixing seat 9. The output end of the blower 10 extends below the second fixing seat 9 and is fixedly connected to a pipe body 11. A plurality of nozzles 12 are fixedly arrayed at the bottom end of the pipe body 11.
[0024] Specifically, such as Figures 1-4As shown, a storage battery 13 is fixedly installed inside the battery box 3, and a PLC controller 14 is fixedly installed on the upper part of the support rod 2. The cylinder 6, the blower 10, and the PLC controller 14 are all electrically connected to the output terminal of the storage battery 13, and the cylinder 6 and the blower 10 are all electrically connected to the output terminal of the PLC controller 14. The start and stop of the cylinder 6 and the blower 10 can be controlled by the PLC controller 14.
[0025] Specifically, such as Figures 1-4 As shown, studs 15 are fixedly provided on the upper and lower parts of the battery box 3. The top end of the support rod 2 and the bottom end of the support rod 4 are provided with threaded grooves that match the studs 15. By providing studs 15, it is convenient to disassemble and assemble the battery box 3.
[0026] Specifically, such as Figures 1-4 As shown, each of the fixed bases 5 has a sliding rod 17 symmetrically slidably inserted on the side near the fixed plate 7. One end of each sliding rod 17 is fixedly connected to the fixed plate 7. When the fixed plate 7 moves, the fixed plate 7 will drive the sliding rod 17 to move within the fixed base 5. The sliding rod 17 can support the fixed plate 7.
[0027] Specifically, such as Figures 1-4 As shown, the fixed base 2 9 has several ventilation holes arranged in an array. The tube body 11 is symmetrically fitted with brackets, and the top of each bracket is fixedly connected to the bottom of the fixed base 2 9.

[0029] The working principle of this utility model is as follows: When in use, the device is placed in a suitable position, and asphalt is placed in the repair shell 1. Then, the device is pushed to move. At this time, the blower 10 works, which can deliver compressed air to the pipe 11 and spray it through the nozzle 12, thereby blowing out the dirt in the crack. Then, the asphalt in the repair shell 1 will fall into the crack. When one crack is repaired, the cylinder 6 drives the fixed plate 7 to move, so that the fixed plate 7 drives the scraper 8 to insert into the repair shell 1, thereby scraping up the remaining asphalt. At this time, the device can be moved to another crack, thus avoiding material waste. When the fixed plate 7 moves, the fixed plate 7 will drive the slide rod 17 to move in the fixed seat 5. The slide rod 17 can support the fixed plate 7.
