[0031] The support plate 17 is also connected to a connecting plate 18, which is connected to a hook. The hook can be used to connect to the vehicle, and the vehicle can drive the support plate 17 to move through the connecting plate 18. The support plate 17 is also connected to a counterweight block, which can provide sufficient downward pressure to facilitate the opening of a crack in the road surface.

[0032] The two ends of the support rod 11 are fixedly connected with a connecting seat 13, and the connecting seat 13 is rotatably connected to the support leg 16. The support plate 17 is also connected with a filling mechanism for filling the gaps in the asphalt pavement. The filling mechanism adopts a conventional filling mechanism. The filling mechanism can realize the falling of the asphalt material, and the pavement can be opened according to the required width of the pavement. The gaps opened are then filled by the filling mechanism, so as to achieve the purpose of fast and efficient, saving raw materials, and will not cause unnecessary damage to the pavement, thereby realizing the rapid repair of the pavement.

[0033] The support rod 11 is fixedly connected with a grinding cylinder 1, which is arranged at the middle part of the support rod 11. A plurality of grinding pins 2 are arranged on the surface of the grinding cylinder 1. Both ends of the grinding cylinder 1 are slidably connected with telescopic cylinders 8 that move horizontally.

[0034] The support rod 11 is provided with a scale 12 on its surface. Through the scale 12 , the width of the cracked road surface can be adjusted as required. Under the action of the scale 12 , the length of the telescopic cylinder 8 extending out of the grinding cylinder 1 can be easily adjusted.

[0035] The telescopic cylinder 8 is provided with a plurality of sliding holes, in which the telescopic nail 4 is slidably connected. The telescopic nail 4 is sleeved with a spring 5, one end of the spring 5 is connected to the telescopic nail 4, and the other end of the spring 5 is connected to the telescopic cylinder 8.

[0036] A cavity is defined in the telescopic cylinder 8 , the cavity is communicated with the sliding hole, and the spring 5 is located in the cavity.

[0037] An inner cylinder 6 is rotatably arranged in the cavity, and both ends of the inner cylinder 6 are rotatably connected to telescopic cylinders 8. A plurality of top blocks 7 are fixedly connected to the outer surface of the inner cylinder 6.

[0039] The top block 7 is arranged between the telescopic nail 4 and the inner cylinder 6. When the telescopic nail 4 contacts the horizontal plane, the telescopic nail 4 and the grinding nail 2 are flush with each other in height.

[0040] When the inner cylinder 6 rotates, the top blocks 7 at different positions drive different telescopic nails 4 to extend. The telescopic nails 4 located outside the telescopic cylinder 8 have slid onto the horizontal plane via the inclined surface 71, and this part of the telescopic nails 4 can slide on the horizontal plane.

[0041] The spring 5 is used for resetting the telescopic pin 4. When the telescopic cylinder 8 moves into the grinding cylinder 1, the top block 7 is no longer in contact with the telescopic pin 4. Under the action of the spring 5, the telescopic pin 4 can be moved into the telescopic cylinder 8, thereby not affecting the normal movement of the telescopic cylinder 8.

[0043] The telescopic cylinder 8 is rotatably connected to a traveling gear 10, and a threaded groove is provided on the inner ring of the traveling gear 10. The threaded groove is threadedly connected to the support rod 11. When the traveling wheel 10 rotates, since the telescopic cylinder 8 and the grinding cylinder 1 can only slide, the telescopic cylinder 8 can be driven to slide in or out relative to the grinding cylinder 1.

[0044] The telescopic cylinder 8 is rotatably connected to a rotating shaft 23, and pinions 15 and power wheels 14 are fixedly sleeved at both ends of the rotating shaft 23. One end of the rotating shaft 23 extending from the telescopic cylinder 8 is fixedly connected to a toggle block 141.

A hexagonal threaded hole is also provided in the toggle block 141, and the toggle block 141 can be driven to rotate through corresponding tools.

[0045] The inner cylinder 6 is fixedly connected with a large gear 9, a small gear 15 meshes with the large gear 9, and a power wheel 14 meshes with a traveling gear 10. The diameter of the large gear 9 is larger than the diameter of the power wheel 14. In actual operation, according to the height of the inclined surface 71 of the top block 7, a large gear 9 with a suitable gear ratio can be relatively arranged, so that when the telescopic nail 4 moves out of the grinding cylinder 1, the telescopic nail 4 will contact the top block 7, and at this time, the inner cylinder 6 rotates, and the telescopic nail 4 will be driven to extend through the top block 7.

[0047] The motor 19 can drive the output shaft to rotate, and the output shaft can drive the two belts 20 to rotate, thereby driving the grinding cylinder 1 and the cleaning wheel 21 to rotate.

[0048] The present invention also proposes a method for using the asphalt pavement quick repair device, which also includes the asphalt pavement quick repair device of the above item, including the following steps:

[0049] S1: The rotating shaft 23 is driven to rotate by the toggle block 141, the rotating shaft 23 drives the pinion 15 and the power wheel 14 to rotate, the power wheel 14 drives the travel gear 10 to rotate, and the pinion 15 drives the inner cylinder 6 to rotate through the large gear 9;

[0050] S2: The traveling gear 10 rotates around the supporting rod 11, thereby driving the telescopic cylinder 8 to move away from the grinding cylinder 1. At the same time, the inner cylinder 6 drives the top block 7 to rotate. Under the action of the top block 7, the telescopic nail 4 that has moved out of the telescopic cylinder 8 moves away from the inner cylinder 6. At this time, the spring 5 corresponding to the telescopic nail 4 located outside the telescopic cylinder 8 is compressed.

[0051] S3: As the rotating shaft 23 rotates, the telescopic cylinder 8 is moved out to a specified length according to the width of the road surface to be repaired. At this time, the telescopic nail 4 located outside the telescopic cylinder 8 contacts the horizontal plane, and the telescopic nail 4 located outside the telescopic cylinder 8 is flush with the grinding nail 2.

[0052] S4: Connect the connecting plate 18 to the vehicle, and the vehicle drives the supporting plate 17 to move. Under the action of the grinding nails 2 and the telescopic nails 4, the road surface is cracked, and the material produced by the cracking enters the collecting box 22. The filling mechanism fills the gap in the asphalt road surface to complete the repair of the asphalt road surface.

[0053] It should be noted that when the traveling gear 10 rotates, due to the threaded connection between the traveling gear 10 and the support rod 11, the telescopic cylinder 8 can be driven to move in the direction away from the grinding cylinder 1. According to the required width of the road surface repair, the telescopic cylinder 8 can be moved out to different lengths. At the same time, when the rotating shaft 24 rotates, it can drive the inner cylinder 6 to rotate, and the inner cylinder 6 can drive the top block 7 to rotate. The top blocks 7 at different positions can drive different telescopic nails 4 to extend, so that the telescopic nails 4 moved out of the telescopic cylinder 8 are pushed out under the action of the top block 7. At this time, this part of the telescopic nails 4 is flush with the grinding nails 2, and the seam opening work of roads of different widths can be carried out, which is convenient for the subsequent repair work, so as to achieve the purpose of fast and efficient, saving raw materials, and will not cause unnecessary damage to the road surface, thereby realizing the rapid repair of the road surface.
