For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication between them; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0035] Example 1

[0036] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Figure 1-Figure 5 The structure of the pavement arching disease repair device is described in general. Specifically, Figure 1-Figure 3 It is a schematic structural diagram of various angles of the pavement arch and expansion disease repair device according to an embodiment of the utility model.

[0038] like Figure 1-Figure 5As shown, the pavement arch disease repair device provided by the utility model includes a vehicle body 1, a milling unit, a gravel collection unit and a material mixing unit arranged on the vehicle body 1; the milling unit includes a milling wheel 17 arranged at the bottom of the vehicle body; the gravel collection unit includes a liftable gravel shovel 7 and a gravel collection frame 11, and the gravel shovel 7 is connected to the output end of the rotation drive device 9; along the moving direction of the vehicle body 1, the gravel shovel 7 is arranged at the rear side of the milling wheel 17, and the gravel collection frame 11 is arranged at the rear side of the gravel shovel 7; the material mixing unit includes a mixing barrel 201, a feed port 210 is arranged at the top of the mixing barrel 201, and a discharge port 208 is arranged at the bottom of the mixing barrel 201.

[0039] The pavement arching and swelling defect repairing device of the present invention moves the vehicle body 1 to the pavement arching and swelling defect location to be constructed, then starts the milling wheel 17 to excavate the pavement arching and swelling defect location, while lowering the liftable gravel shovel 7 to a height close to the ground. As the vehicle body 1 moves forward, the gravel shovel 7 collects the gravel formed by the milling wheel 17 excavating the pavement arching and swelling defect location. When the gravel carrying capacity of the gravel shovel 7 reaches its preset load, the gravel shovel 7 rises to the corresponding height of the gravel collection frame 11. The rotary drive device 9 is started, and the output end of the rotary drive device 9 drives the gravel shovel 7 to tilt toward the gravel collection frame 11, completing the action of dumping the gravel in the gravel shovel 7 into the gravel collection frame 11. After the gravel shovel 7 completes the dumping, it continues to descend to collect the gravel, and this cycle repeats. Simultaneously, repair material is added to mixing barrel 201 and, after being mixed evenly, discharged from the discharge port and dropped into the grooves excavated by milling wheel 17 at the affected area, completing the repair of the affected area. By placing the milling unit, gravel collection unit, and material mixing unit on a mobile vehicle, the vehicle automatically completes the process of excavating the affected area, collecting gravel, and filling the grooves with repair material as it moves. Compared to existing technologies, this eliminates the labor loss associated with manual gravel removal, significantly reduces workload, and improves repair efficiency.

[0040] In order to further improve the efficiency of repair construction, a scraper plate 13 and a smoothing roller 14 are sequentially arranged on the rear side of the discharge port 208 along the direction of travel of the vehicle body. In the specific implementation process, a truck bucket is arranged on the rear side of the vehicle body 1 along the direction of travel of the vehicle body 1, and the material mixing unit is arranged on the truck bucket. In other words, the mixing barrel is arranged above the truck bucket, and the scraper plate 13 and the smoothing roller 14 are arranged at the bottom of the vehicle. In other words, the scraper plate 13 and the smoothing roller 14 are at the same level as the milling wheel and the gravel shovel in the gravel collecting working position. It should be noted that in road repair, a scraper plate is usually used to spread asphalt or concrete repair materials. It can evenly distribute the material on the road surface, ensuring the consistency of the material laying and the uniformity of the thickness. After the material is laid, the smoothing roller is used to further compact and level the road surface. They compact the paved material by rolling, eliminating bubbles and unevenness on the surface, thereby ensuring the smoothness and durability of the road surface. The scraper plate and smoothing roller do not need to be installed on the pavement arch disease repair device of the present invention, and can be operated manually separately later. No specific limitation is made here, and the selection is made according to the specific application scenario. Through the above-mentioned arrangement, the milling wheel excavates first, followed by the gravel shovel to clean the gravel, and then the discharge port outputs the repair material. Finally, the scraper plate 13 flattens the repair material, and the smoothing roller performs the smoothing operation in an assembly line manner, which greatly improves the repair efficiency. Moreover, the above-mentioned devices are uniformly arranged on the vehicle body and driven by the vehicle body, without the need to set up a separate displacement drive system for each.

[0041] As an improvement to this embodiment, a gravel collection chamber is provided on the vehicle body 1, and a fixing frame 3 and an electric telescopic rod 4 are provided above the gravel collection chamber. The top end of the electric telescopic rod 4 is connected to the fixing frame 3, and the bottom end of the electric telescopic rod 4 is connected to a fixing frame 5; the gravel shovel 7 is provided in the fixing frame 5 via a rotating shaft 6; the rotating shaft 6 is connected to the output end of the rotating drive device 9. Figure 1 As shown, a continuous gravel collection chamber is provided on the vehicle body. Within the entire gravel collection chamber, the gravel shovel has a gravel collection position at the bottom and a gravel dumping position at the top, allowing the gravel shovel to move freely up and down as needed. To enable the gravel shovel to be raised and lowered, an elevated mounting bracket is provided on the vehicle body 1. In one specific embodiment, the mounting bracket 3 is an inverted U-shaped bracket, which suspends the gravel shovel in the gravel collection chamber via a liftable assembly. The liftable assembly can be either hydraulic or electric, enabling the gravel shovel to move between the gravel collection position and the gravel dumping position. In one specific embodiment, the liftable assembly is an electric telescopic rod.

[0042] Figure 4 This is a schematic diagram of the structure of the rotary drive transmission structure of the road surface arch and expansion disease repair device according to the embodiment of the utility model. Figure 4As shown, in order to realize the action of dumping gravel when the gravel shovel is in the gravel dumping working position, the rotation drive device 9 is a motor, a turbine 8 is provided on the rotating shaft 6, and a worm 10 is connected to the output end of the motor, and the turbine 8 is engaged with the worm 10. In general, in the present utility model, the gravel shovel 7 is first driven downward by the electric telescopic rod 6 until it contacts the groove excavated by the milling wheel 17. When the device moves, the gravel shovel 7 collects the excavated gravel, and then the gravel shovel 7 is driven upward by the electric telescopic rod 6 to a designated position. Then, the micro motor can drive the worm to rotate, and the worm gear will rotate accordingly, thereby driving the gravel shovel 7 to tilt. At this time, the gravel in the gravel shovel 7 will be poured into the gravel collection frame 11, and the staff does not need to hold a shovel to clean it, thereby reducing the staff's workload. However, it cannot meet the needs of users.

[0043] In general, a repair structure for highway pavement arching and swelling diseases includes a vehicle body 1, a U-shaped fixing frame 3 is fixedly connected to the top of the vehicle body 1, an electric telescopic rod 4 is fixedly connected to the inner top of the U-shaped fixing frame 3, one end of the electric telescopic rod 4 is fixedly connected to a fixing frame 5, the interior of the fixing frame 5 is rotatably connected to a rotating shaft 6, the outer side of the rotating shaft 6 is fixedly connected to a gravel shovel 7, the front side of the outer wall of the rotating shaft 6 is fixedly connected to a worm gear 8, a micro motor 9 is fixedly connected to the middle and upper front part of the shovel frame 7, the output end of the micro motor 9 is fixedly connected to a worm 10, and the worm 10 is meshed with the worm gear 8.

[0045] Figure 5 This is a schematic diagram of the structure of the stirring assembly of the pavement arching disease repair device according to the embodiment of the utility model.

That is to say, the stirring rod group is arranged in the length direction of the first rotating rod 204 and the second rotating rod 205 according to the set spacing. The specific spacing is specifically set according to the composition of the repair material. As an improvement of this embodiment, the stirring rod group includes 3-8 stirring rods 207; the stirring rods 207 are evenly arranged on the circumference of the first rotating rod 204 or the second rotating rod 205. In a specific implementation process, as Figure 5 As shown, a stirring rod set includes four stirring rods 207. The servo motor can drive the first rotating rod 204 to rotate clockwise, and the gear on the first rotating rod 204 will rotate accordingly. The gear meshing with the first rotating rod 204 will then rotate counterclockwise, thereby driving the second rotating rod 205 to rotate.

Specifically, the servo motor 203 can drive the first rotating rod 204 to rotate clockwise. The first rotating rod 204 rotates, and the gear 206 installed on its outside also rotates synchronously. This gear is tightly meshed with another gear. When the first gear rotates, the second gear 206 is subjected to a reverse torque, thereby realizing counterclockwise rotation. This counterclockwise rotation is further transmitted to the second rotating rod 205, causing it to also rotate counterclockwise. During this process, the stirring rods 207 on the first rotating rod 204 and the second rotating rod 205 rotate at the same time to continuously and evenly stir the repair material inside the mixing barrel 201. This sufficient stirring process can ensure that the repair material reaches the best mixing state before use, thereby ensuring the stability of its performance and quality.
