[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 5As shown, this utility model provides a rapid repair device for potholes on highway surfaces, including a frame 11. A lifting assembly and a compaction assembly are located on the top of the frame 11. The lifting assembly, consisting of a lifter 12 and a guide rod 13, enables the lifting and lowering of the compaction assembly to accommodate potholes of varying depths. The compaction assembly is connected to the frame 11 via the lifting assembly and includes a compaction plate 14. The compaction plate 14 directly acts on the potholes to compact the repair material. The compaction plate 14 has a three-layer structure: from the inside out, a heating layer 15, a feedback layer 16, and a protective layer 17. The heating layer 15 is a graphene heating film; the feedback layer 16 consists of an epoxy matrix and an embedded piezoelectric ceramic 36; the protective layer 17 is a steel plate that encloses the heating layer 15 and the feedback layer 16; and a controller 33 is electrically connected to the piezoelectric ceramic 36. The heating layer 15 preheats the surface of the tamping plate 14 before operation, softening the repair material and improving the interfacial bonding strength. Information such as tamping pressure is fed back to the controller 33 via the piezoelectric ceramic 36, allowing for adjustment of tamping parameters. The steel plate of the protective layer 17 isolates the material from external impacts and corrosive media, extending the lifespan of the heating layer 15 and the feedback layer 16. The piezoelectric ceramic 36 can be a PZT-5H model. A feeding assembly is provided on the frame 11, including a raw material bin 22. The raw material bin 22 is equipped with a stirring device, and a discharge hopper 26 is located at one end of the frame 11. The discharge hopper 26 is connected to the raw material bin 22 via a conveying pipe 25. The feeding assembly, consisting of the raw material bin 22, stirring rod 23, stirring motor 24, conveying pipe 25, discharge hopper 26, spiral guide rod 27, and drive motor 28, can store, stir, and transport repair material to the pits and depressions. At the other end of the frame 11 is a leveling assembly; this assembly, consisting of a scraper plate (29), a support frame (31), and an expansion joint (32), can level the repair material filled in potholes, ensuring a smooth road surface. The frame 11 also has a controller (33). The controller (33) allows for centralized control of all components, enabling automated operation. The controller (33) can be an ATSAME70 model controller.

[0026] The compaction assembly also includes a mounting frame 18 and a vibratory motor 19. The compaction plate 14 is connected to the mounting frame 18, and multiple sets of buffers 21 are provided at the connection point. The buffers 21 reduce the impact of vibrations generated during compaction on the mounting frame 18 and other components, protecting the equipment and extending its service life. The mounting frame 18 is mounted on the frame 11 via a lifting assembly. The vibratory motor 19 is mounted on the compaction plate 14, and the controller 33 is electrically connected to the vibratory motor 19. Through the connection between the vibratory motor 19 and the controller 33, the controller 33 can control the operation of the vibratory motor 19, adjust the compaction intensity, and adapt to the compaction needs of different pits and depressions.

[0027] like Figure 2As shown, the lifting assembly includes two sets of lifting devices 12 and four sets of guide rods 13. All three sets are mounted on the frame 11. The movable rods of the two sets of lifting devices 12 are connected to the mounting frame 18. One end of each guide rod 13 passes through the four corners of the mounting frame 18. The lifting devices 12 and guide rods 13 provide power and guidance for the lifting of the mounting frame 18, ensuring smooth lifting. The controller 33 is electrically connected to the lifting devices 12. This electrical connection allows the controller 33 to control the lifting action of the lifting devices 12, meeting the needs of different working conditions.

[0028] A spiral guide rod 27 is installed inside the conveying pipe 25, and a drive motor 28 is installed on the frame 11. The output shaft of the drive motor 28 is connected to the spiral guide rod 27, and the controller 33 is electrically connected to the drive motor 28. Through the arrangement of the spiral guide rod 27, the drive motor 28, and their connection with the controller 33, the controller 33 can control the drive motor 28 to drive the spiral guide rod 27, thereby controlling the amount of repair material conveyed in the conveying pipe 25.

[0029] The mixing device includes a mixing rod 23 and a mixing motor 24. The mixing motor 24 is mounted on top of the raw material tank 22, and the mixing rod 23 is located inside the raw material tank 22. The mixing rod 23 is connected to the output shaft of the mixing motor 24, and the controller 33 is electrically connected to the mixing motor 24. Through the arrangement of the mixing rod 23, the mixing motor 24, and their connection with the controller 33, the controller 33 can control the mixing motor 24 to drive the mixing rod 23, thereby thoroughly and evenly mixing the repair material in the raw material tank 22.

[0030] like Figure 2 , 3 As shown, the leveling assembly includes a scraper plate 29 and a support frame 31. One end of the support frame 31 is rotatably connected to the frame 11, and the scraper plate 29 is installed at the other end of the support frame 31. Through the arrangement of the scraper plate 29 and the support frame 31, the repaired road surface can be leveled to ensure its smoothness. The frame 11 is equipped with an expansion joint 32. The movable rod of the expansion joint 32 is connected to the support frame 31, and the controller 33 is electrically connected to the expansion joint 32. Through the expansion joint 32 and its connection to the controller 33, the controller 33 can control the expansion joint 32 to adjust the angle and position of the scraper plate 29.

[0031] The frame 11 is equipped with a push rod 34; two sets of wheels 35 are provided on both sides of the frame 11. The push rod 34 and wheels 35 make it easy for the operator to move the device and make it work in different pit and uneven locations.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In use, the operator holds the push rod 34 and pushes the device to the pothole on the road surface using the wheels 35 on both sides of the frame 11. Then, the mixing motor 24 is started, driving the mixing rod 23 to thoroughly mix the repair material in the material box 22, ensuring uniform mixing. Next, the controller 33 operates the drive motor 28, driving the spiral guide rod 27 in the conveying pipe 25 to transport the material from the material box 22 to the pothole via the discharge hopper 26. At this time, the controller 33 controls the lifting device 12, which, through its movable rod, smoothly lowers the mounting frame 18 and the compaction plate 14 to a suitable height under the guidance of the guide rod 13. The vibration motor 19 is started, causing the compaction plate 14 to vibrate and compact the repair material. Simultaneously, the graphene heating film 15 inside the compaction plate 14 heats the material to enhance adhesion. The piezoelectric ceramic 36 in the feedback layer 16 feeds pressure information back to the controller 33 to adjust the parameters of the vibration motor 19 and control the compaction force. The buffer 21 reduces vibration impact and protects the equipment. After compaction, the controller 33 operates the expansion joint 32 to adjust the angle and position of the scraper plate 29 on the support frame 31 through its movable rod, so as to scrape the repair material flat.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
