Technical Field

[0001] This utility model relates to the field of road repair equipment technology, specifically to an energy-saving asphalt concrete road surface repair device. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. Asphalt pavement is a widely used structure in highway engineering in my country. With the increasing number of vehicles, the surface of asphalt pavement will be damaged after long-term use. At this time, it is necessary to renovate and repair the asphalt pavement. In order to improve the repair efficiency and the strength after repair, a repair layer is laid directly on the original pavement.

[0003] Among them, announcement number CN222575215U discloses an asphalt pavement repair device, which uses a parallel double pressure roller mechanism with intervals. Specifically, a groove is opened at the bottom of the other side of the tractor body, and a fixed frame is fixedly connected to the front and rear ends of the top wall of the groove. Two pressure rollers are installed in parallel and rotating between the two fixed frames with intervals. After the two pressure rollers squeeze the cracked asphalt surface of the asphalt mixture twice, it can achieve a good compaction effect of the asphalt mixture in the crack of the damaged asphalt pavement.

[0004] However, in actual use, after a long period of use, the surface of the road will develop pits. The device sprays asphalt concrete evenly onto the road surface through the spray head. When it encounters a pit, the amount of spray is insufficient to fill the pit completely, which can easily lead to subsequent road surface depressions, resulting in water accumulation and a reduced service life of the repaired road surface.

[0005] Therefore, it is necessary to invent an energy-saving asphalt concrete road surface repair device to solve the above problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1 to 5An energy-saving asphalt concrete road surface repair device is shown, comprising a mobile vehicle body 1. An asphalt tank 11 is fixedly installed on the rear side of the upper surface of the mobile vehicle body 1. An asphalt pump 12 is fixedly installed on the side of the asphalt tank 11. The discharge end of the asphalt tank 11 is fixedly connected to the inlet end of the asphalt pump 12. A conveying pipe 13 is fixedly connected to the discharge end of the asphalt pump 12. Multiple sets of pressure rollers 16 are rotatably connected to the lower side of the mobile vehicle body 1. A spraying assembly is provided at the front end of the mobile vehicle body 1. The spraying assembly includes a controller 14, control buttons 15, a diverter pipe 2, a first connector 21, a second connector 22, an electric valve 23, a first connecting pipe 24, a second connecting pipe 25, a first discharge head 26, a third connecting pipe 27, and a second discharge head 28. The controller 14 is fixedly installed at the front side of the upper surface of the mobile vehicle body 1. Multiple sets of control buttons 15 are installed on the upper surface of the controller 14. The controller 14 is electrically connected to multiple sets of electric valves 23 and the asphalt pump 12.

[0028] The asphalt material inside the asphalt tank 11 is a recycled asphalt mixture, which effectively improves resource utilization and achieves energy saving. The mobile vehicle 1 drives the pressure roller 16 to rotate through the drive mechanism, thereby moving the entire equipment. The drive structure is existing technology and will not be described in detail here. During use, the asphalt material is stored inside the asphalt tank 11 and continuously heated by the heating plate on the lower side to prevent it from solidifying. When the equipment moves, the asphalt pump 12 draws the asphalt material inside the asphalt tank 11 to the first discharge head 26. The first discharge head 26 spreads the asphalt material evenly on the surface of the road base. Then, multiple sets of pressure rollers 16 work together to compact it. When a pothole is encountered during paving, the electric valve 23 on the upper side of the second discharge head 28 corresponding to the pothole is activated by the control button 15. At this time, the asphalt material is filled into the pothole from the second discharge head 28, increasing the discharge volume at the pothole, maintaining the flatness of the compacted road surface, improving construction quality and road safety.

[0029] See Figures 3 to 5 The diversion pipe 2 is fixedly connected to the front end of the mobile vehicle body 1. The front end of the conveying pipe 13 is fixedly connected to the middle position of the lower side of the diversion pipe 2. The front and rear ends of the diversion pipe 2 are fixedly connected to the first connector 21. Multiple sets of second connectors 22 are fixedly connected to the upper side of the diversion pipe 2. Electric valves 23 are installed on the surfaces of the first connectors 21 and the second connectors 22. The outer ends of the two sets of first connectors 21 are fixedly connected to the first connecting pipes 24. The two ends of the second connecting pipes 25 are fixedly connected to the front ends of the two sets of first connecting pipes 24 respectively. Multiple sets of first discharge heads 26 are fixedly connected to the lower surface of the second connecting pipes 25. The front ends of the multiple sets of second connectors 22 are fixedly connected to the third connecting pipes 27. The front ends of the multiple sets of third connecting pipes 27 are fixedly connected to the second discharge heads 28.

[0030] Specifically, during the discharge process, the asphalt pump 12 draws the asphalt material from the asphalt tank 11 and then transports it through the conveying pipe 13 to the inside of the diversion pipe 2. At this time, the asphalt material inside the diversion pipe 2 is transported to the inside of the second connecting pipe 25 through the first connector 21 and the first connecting pipe 24 at both ends. The second connecting pipe 25 discharges the asphalt material evenly through multiple sets of first discharge heads 26 to maintain the smoothness of the road surface. At the same time, when a pothole appears on the road surface, the corresponding electric valve 23 is activated according to the location of the pothole, and the corresponding second connector 22 is opened. At this time, the asphalt material inside the diversion pipe 2 is transported to the inside of the second discharge head 28 through the second connector 22 and the third connecting pipe 27. Then, the asphalt material is discharged into the pothole through the second discharge head 28, increasing the discharge amount of asphalt material at the pothole to fill it, thereby effectively maintaining the smoothness of the compacted road surface.

[0031] See Figure 1 , Figure 3 and Figure 6 A support frame 3 is fixedly connected to the front end of the mobile vehicle body 1 near the lower side. Two sets of mounting rods 31 are fixedly connected to the upper surface of the support frame 3. Multiple sets of fixing frames 32 are slidably connected to the surface of the mounting rods 31. A locking screw 33 is threaded to the front end of the fixing frame 32. A snap ring 34 is fixedly connected to the rear end of the fixing frame 32. The first discharge head 26 and the second discharge head 28 are both snapped inside the snap ring 34.

[0032] In addition, the snap ring 34 consists of two sets of arc-shaped spring plates. During installation, the first row of material heads 26 and the second row of material heads 28 can be directly snapped into the inside of the snap ring 34 to fix the first row of material heads 26 and the second row of material heads 28. This makes it easy to replace the first row of material heads 26 and the second row of material heads 28 when they are damaged.

[0033] The working principle of this utility model is as follows: Asphalt material is discharged outward through multiple sets of first discharge heads 26, and the asphalt material is evenly distributed on the surface of the road base. When a pothole is encountered, the electric valve 23 on the upper side of the second discharge head 28 opposite to the pothole is opened by the control button 15, so that the asphalt material is sprayed outward through the second discharge head 28, increasing the amount of material sprayed at the pothole, making it easier to fill the pothole, so that the road surface remains flat after compaction, thereby effectively preventing the road surface from sinking and effectively improving the service life of the road.
