Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to an asphalt highway crack filling and repairing device. Background Art

[0002] The crack problem of asphalt pavement is a complex and common phenomenon. There are many reasons for its occurrence, such as poor asphalt quality or insufficient asphalt dosage. In the case of extremely low temperature or rapid temperature drop, the temperature stress of the asphalt surface layer cannot be relieved in time, resulting in shrinkage cracks. All of these may cause cracks in the pavement when the temperature changes. In addition, the construction method and process are also important reasons for the cracks. Insufficient strength of the roadbed or base structure, uneven rolling, unreasonable mechanical combination, etc. may all lead to cracks in the pavement;

[0003] As the cracks grow larger, rainwater or snow water will gradually invade, causing the water content of the pavement structure or soil base on both sides of the cracks to increase, or even reach saturation, which will significantly reduce the bearing capacity of the structural layer. Under the action of a large amount of traffic load, scouring and pumping will occur, thereby accelerating the damage to the pavement. Therefore, it is necessary to repair the cracks in the pavement in a timely manner. For example, the Chinese utility model patent disclosed in the publication number CN217324922U: A asphalt pavement repair device for municipal engineering, the application can integrate repair and paving, reduce the number of tools to be carried, increase the scope of use, and the device can It can protect the users, has strong stability, good protective effect, and is easy for staff to operate. However, on the one hand, the application needs to cooperate with the continuous pouring of asphalt to repair the cracks in the road surface. The operation process is not convenient. At the same time, it is impossible to adjust the width of the repair asphalt paving according to the width of the road surface cracks. In addition, when the asphalt flows to the road surface, it will also flow to both sides for an unfixed distance, and after the roller pressure, the width of the asphalt for repair is different, and the asphalt for repair is easy to adhere to the roller, which makes it impossible to effectively pour asphalt into some cracks, resulting in unsatisfactory road surface crack repair effect.

[0022] like Figure 2-Figure 5 As shown, two second connection blocks 15 are fixedly installed on one side of the two limiting plates 8, and the first rotation groove 16 is respectively opened on the opposite side of the two second connection blocks 15. The two second connection blocks 15 are respectively opened on the opposite side to each other. The second rotation groove 18 is opened in the limiting groove 17. The two limiting plates 8 are respectively opened on the opposite side. A slot 14 is opened, and a push piece 26 is movably connected between the two slots 14. Insertion blocks 27 are fixedly installed on both sides of the push piece 26. The transverse section of the insertion block 27 is T-shaped, and the insertion block 27 is inserted and installed in the corresponding slot 14, and is arranged by using a deformable push piece 26. After the angles of the two limiting plates 8 change, the asphalt in the two limiting plates 8 can be evenly spread in the cracks of the road surface. The connecting shaft 10 and the sleeve 11 are both arc-shaped structures. A fixing ring 28 is fixedly installed on the outside of the connecting shaft 10. The connecting shaft 10 on one side of the fixing ring 28 is inserted and installed in the through hole of the corresponding limiting plate 8 and fixed by a nut. The two sides of the sleeve 11 are respectively inserted and installed on one side of the corresponding connecting shaft 10. The arrangement of two connecting shafts 10 and one sleeve 11 can ensure the stability of the connection between the two limiting plates 8 and can support the bottom of the guide groove plate 6.

[0023] Embodiment 2, as Figure 3-Figure 4As shown, a second fixed shaft 20 is fixedly installed on the top of the first connecting block 9, and two first fixed shafts 19 are also fixedly installed on the top and bottom of the first connecting block 9, and the limiting plate 8 is rotatably installed on one side of the first connecting block 9 through the first rotating grooves 16 in the two second connecting blocks 15, and the two limiting gears 13 are respectively fixedly installed on the tops of the fixed blocks 22, and a stud 23 is fixedly installed at the top center position of the fixed block 22, and the limiting gear 13 is inserted and installed in the limiting groove 17, and a connecting piece 24 is inserted and connected between the second fixed shaft 20 and the two studs 23, and a pressure rod 25 is fixedly installed at the top center position of the connecting piece 24, and the second fixed shaft 20 and the stud 23 located above the connecting piece 24 are respectively threadedly connected with nuts, and the second fixed shaft 20 located between the connecting piece 24 and the first connecting block 9 is sleeved with a compression spring, and with the help of the pressure rod 25, the connecting piece 24, the limiting gear 13, the limiting groove 17 and the second rotating groove 18, the angles of the two limiting plates 8 can be quickly adjusted and fixed.

[0024] It should be noted that the utility model is an asphalt highway crack filling and repairing device. When repairing cracks in the road surface, the width of the asphalt paving can be adjusted according to the width of the cracks currently being repaired, that is, the pressure rod 25 can be pressed down with one hand, so that the pressure rod 25 synchronously drives the two fixed blocks 22 to move downward through the connecting piece 24, and makes one side of the connecting piece 24 also move up and down on the second fixed shaft 20 and compress the compression spring on the second fixed shaft 20 toward the first connecting block 9. Therefore, the two fixed blocks 22 respectively drive the limiting gear 13 at the lower end to move from the limiting groove 17 to the corresponding second rotating groove 18, so that the two limiting plates 8 can respectively rotate on the first connecting block 9 with the two second connecting blocks 15 on one side as the axis. At the same time, the two limiting plates 8 also respectively drive the connecting shaft 10 on one side to move synchronously, and make one side of the connecting shaft 10 move in the sleeve 11, thereby ensuring that the sleeve 11 can continue to support the bottom of the guide groove plate 6. In addition, with the two limiting plates 8 The change in angle will also change the curvature of the push piece 26. When the angle adjustment of the two limiting plates 8 is completed, the connecting piece 24 can be loosened, and then the connecting piece 24 can be reset with the help of the force of the compression spring on the outer side of the second fixed shaft 20, so that the connecting piece 24 drives the two fixed blocks 22 to move up synchronously. Then, the fixed block 22 drives the limiting gear 13 to flush and move into the corresponding limiting groove 17, and the second connecting block 15 can be rotationally limited. Therefore, after the angle adjustment of the two limiting plates 8 is completed, the asphalt paving width can be adjusted. Subsequently, the valve on one side of the asphalt heating box 4 is opened through the operating lever on the side of the handrail 3, so that the asphalt in the asphalt heating box 4 can flow through the guide groove plate 6 to the road surface between the two limiting plates 8, and the asphalt heating box 4 is pushed to move through the handrail 3 and the frame 1, so that the pull rod 21 cooperates with the first connecting block 9 to synchronously drive the two limiting plates 8 to move, and then the asphalt is spread and scraped into the cracks in the road surface with the help of the push piece 26.
