[0019] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 6 As shown, an embodiment of the present invention provides an intelligent road surface repair and reinforcement equipment, including a frame 12, a drilling device, a grouting device, a road surface cutting device, and a negative pressure waste collection device. The drilling device, grouting device, road surface cutting device, and negative pressure waste collection device are integrated and assembled on the frame 12. The frame 12 is provided with a vehicle-mounted connection structure, which can be mounted on an engineering vehicle and transported to the work site with the vehicle. The drilling device and the grouting device share a hollow special steel pipe 1 to simultaneously realize roadbed drilling and deep grouting reinforcement. The road surface cutting device and the drilling device share a cooling and dust suppression water circuit to simultaneously realize operation cooling and dust suppression. The negative pressure waste collection device operates synchronously with the road surface cutting operation and is used to collect debris generated by road surface cutting. The drilling device is used to form grouting holes 9 in the roadbed, and the road surface cutting device is used to break up and clean the damaged road surface. The machine is mounted on a vehicle-mounted connection structure on frame 12 and transported to the road defect site by the vehicle. Upon arrival at the work area, the entire machine is positioned to carry out road defect treatment. The drilling device performs roadbed drilling, forming grouting holes 9 inside the roadbed; the grouting device reuses the same hollow special steel pipe 1, through which grouting reinforcement is carried out deep into the roadbed. The road cutting device performs damaged road surface removal and cleaning. During the operation, the cooling and dust suppression water system simultaneously supplies cooling water to both the drilling and cutting work stations, simultaneously cooling the cutting tools and suppressing dust. The negative pressure waste collection device follows the road cutting operation, collecting road debris generated in real time, completing the entire process of roadbed reinforcement and damaged road surface repair. The equipment achieves integrated operation of multiple working mechanisms, taking into account both transport mobility and the ability to carry out multiple processes simultaneously on site, improving the overall construction efficiency of road defect treatment.

[0021] The drilling device includes the special steel pipe 1, the cooling and dust suppression water pipe 4, and the first hydraulic engine 3; the bottom of the frame 12 is fixed with multiple sets of telescopic support legs 2, and the bottom of the telescopic support legs 2 is provided with an anti-slip support base for leveling and fixing the whole machine during operation; the first hydraulic engine 3 is used to drive the special steel pipe 1 to lift and rotate to complete the drilling and soil removal operations. Before operation, adjust the multiple sets of telescopic support legs 2 at the bottom of the frame 12, and rely on the anti-slip support base at the bottom to level the entire machine and eliminate operational deviations caused by uneven ground. The first hydraulic engine 3 outputs rotational and lifting driving force to drive the specially made steel pipe 1 downward feed, rotating and cutting the soil to complete the roadbed drilling. During drilling, roadbed soil samples can be taken to understand the actual working conditions inside the roadbed. The cooling and dust suppression water pipe 4 supplies water to the drilling point to cool the drill bit of the specially made steel pipe 1 and suppress the rock and soil dust generated during drilling. This ensures the stability of the entire machine during drilling operations, cools the drill bit and suppresses dust while drilling and taking soil, and improves the accuracy of drilling operations and the construction environment.

[0022] The grouting device also includes a cement storage silo 6 and grouting holes 9 arranged in multiple layers along the axial direction of the special steel pipe 1; the cement storage silo 6 is fixedly installed in the middle of the frame 12, and the special steel pipe 1 is vertically fixed to the lower part of the frame 12; an adjustable baffle is provided between the cement storage silo 6 and the special steel pipe 1, and the grouting flow rate is controlled by adjusting the opening of the baffle. After the roadbed drilling process is completed, the grouting material stored inside the cement storage silo 6 is adjusted by changing the opening of the baffle between the outlet and the special steel pipe 1 to change the grout flow cross section, thereby controlling the grout output flow rate. The prepared cement grout enters the inner cavity of the special steel pipe 1 and flows outward along the multi-layered grouting holes 9 distributed axially on the special steel pipe 1. The grout can fill cavities and soft soil disease areas at different depths in the roadbed. The grout gradually solidifies to achieve deep reinforcement of the roadbed. The grouting flow rate can be flexibly controlled, and the grout is output in layers at multiple points, achieving layered grouting reinforcement of disease areas at different depths in the roadbed.

[0023] The road cutting device is installed on the outside of the frame 12 and includes a cutting blade 7, a multi-degree-of-freedom articulated mechanical arm 8 and a second hydraulic engine 10. The second hydraulic engine 10 is used to drive the mechanical arm 8 to swing to adjust the cutting position and cutting depth, and at the same time drive the cutting blade 7 to rotate to cut the damaged road surface. The second hydraulic engine 10 outputs two independent power sources. One power source drives the multi-degree-of-freedom articulated mechanical arm 8 to swing and rotate, thereby adjusting the spatial position and cutting depth of the cutting blade 7 to adapt to the contours of different cracked and collapsed damaged areas of the road surface. The other power source drives the cutting blade 7 to rotate at high speed. The high-speed rotating cutting blade 7 mills and breaks up the damaged concrete and asphalt layers of the road surface, cutting and separating the damaged road surface to create working conditions for subsequent road repair and cleaning. It flexibly adapts to different damaged road surface shapes, precisely adjusts the cutting position and depth, and efficiently completes the cutting and breaking up of damaged road surfaces.

[0024] The cooling and dust suppression water circuit includes a cooling and dust suppression water pipe 4 installed on the outside of the frame 12. The branches of the cooling and dust suppression water pipe 4 are respectively connected to the working area of ​​the cutting blade 7 and the drilling area of ​​the special steel pipe 1. During operation, cooling water is sprayed simultaneously to achieve tool cooling and dust suppression. After the operation starts, cooling water is introduced into the cooling and dust suppression water pipe 4. The water flows through the pipe branches to the working area of ​​the cutting blade 7 and the drilling point of the special steel pipe 1. The cooling water is sprayed directly onto the cutting position of the cutting blade 7 and the cutting position of the drill bit in the special steel pipe 1. On the one hand, it removes a large amount of heat generated by cutting friction, reducing tool thermal wear; on the other hand, the water mist captures dust particles raised by cutting and drilling, causing the dust to settle and reducing the spread of dust at the construction site. One water system serves two work positions simultaneously, achieving tool cooling and dust suppression at the same time, reducing the need for on-site auxiliary water supply equipment.

[0025] The negative pressure waste collection device includes a suction motor 5 and a suction pipe 11; the suction motor 5 is fixedly installed on the upper inner side of the frame 12, and its lower end is connected to the suction pipe 11; a road waste storage bin is provided at the bottom inner side of the frame 12, and the output port of the suction pipe 11 is connected to the inside of the road waste storage bin; during operation, the suction motor 5 generates negative pressure, so that the road cutting debris is sucked into the road waste storage bin through the suction pipe 11 for temporary storage; Simultaneously with the road cutting operation, the suction motor 5 is activated. Operating inside the road waste storage bin at the bottom inner side of the frame 12, the suction motor 5 creates a negative pressure environment. Under this negative pressure, the stone and debris generated during cutting are carried by the airflow and transported through the suction pipe 11, ultimately being sucked into the road waste storage bin for temporary storage. The waste generated during cutting does not require manual on-site cleaning; after all maintenance procedures are completed, the waste inside the storage bin is centrally unloaded and disposed of. Real-time negative pressure collection of cutting debris reduces manual cleaning procedures and lowers the labor intensity of on-site waste removal.

[0026] The vehicle-mounted connection structure includes multiple sets of connecting flanges and quick-locking mechanisms arranged on the top and sides of the frame 12, which can be matched with the installation position of the cargo box of the engineering vehicle to achieve quick assembly and disassembly; in the transfer state, the whole machine is fixed to the cargo box of the vehicle, and in the working state, the whole machine is lifted up by the telescopic support legs 2 to detach from the vehicle chassis. During the equipment relocation and transportation phase, the telescopic support legs 2 retract, and the entire machine is quickly locked and secured to the cargo box mounting position on the engineering vehicle using the connecting flanges and quick-locking mechanisms arranged on the top and sides of the frame 12, allowing it to be transported with the engineering vehicle. Upon arrival at the repair site, the quick-locking mechanism is unlocked, and the telescopic support legs 2 extend to lift the entire machine, detaching it from the vehicle's cargo box chassis. The equipment then relies on the support legs to stand on the ground and independently carry out all repair work. The equipment can be quickly disassembled and mounted on ordinary engineering vehicles, eliminating the need for a dedicated trailer, thus combining convenient relocation with independent on-site operation capabilities.

[0027] An installation cylinder 13 is fixedly installed on the frame 12. A sliding column 14 is slidably installed inside the installation cylinder 13. A first threaded adjusting rod 15 is rotatably installed on the sliding column 14. The first threaded adjusting rod 15 passes through the installation cylinder 13 and is threadedly connected to its inner wall. An installation frame 16 is fixedly installed at the end of the installation cylinder 13 away from the first threaded adjusting rod 15. A traveling wheel 17 is fixedly installed on the installation frame 16. When the equipment needs short-distance relocation or fine-tuning, rotating the first threaded adjusting rod 15, with the help of the feed action of the threaded transmission pair, drives the sliding column 14 to slide axially along the inner wall of the mounting cylinder 13, thereby pushing the mounting frame 16 to extend outward, so that the traveling wheels 17 contact the ground to support the entire machine, thus propelling the equipment to complete a short-distance translation. After the relocation is completed, rotating the adjusting rod in the opposite direction retracts the sliding column 14, removes the traveling wheels 17 from the ground, and the equipment returns to its fixed operating state. The threaded transmission has a self-locking characteristic, which can stably maintain the extended and retracted positions of the traveling wheels 17. Small-range positioning adjustments can be completed without relying on engineering vehicles, improving the positional flexibility of the equipment in on-site operations and reducing the difficulty of alignment.

[0028] A movable plate 18 is slidably installed inside the mounting bracket 16. A movable cavity 19 is opened inside the movable plate 18. A guide push plate 20 is slidably installed inside the movable cavity 19. The guide push plate 20 is V-shaped. A spring 21 is fixedly installed on the guide push plate 20. The end of the spring 21 away from the guide push plate 20 is fixedly connected to the inner wall of the movable cavity 19. An auxiliary wheel 22 is provided on the movable plate 18. A second threaded adjusting rod 23 is threadedly connected to the mounting bracket 16. The second threaded adjusting rod 23 is rotatably connected to the movable plate 18. A handle 24 is provided on the second threaded adjusting rod 23. Rotating handle 24 drives the second threaded adjusting rod 23 to rotate, pushing the movable plate 18 to slide along the inside of the mounting frame 16, adjusting the extension stroke of the auxiliary wheel 22. During equipment movement, if there are obstacles in the forward direction, the guide push plate 20 will guide the obstacles to both sides to avoid affecting the overall movement of the equipment. If a stubborn obstacle is encountered, the guide push plate 20 will retract into the movable cavity 19 and compress the spring 21 to absorb vibration. After the obstacle is passed, the spring 21 rebounds, pushing the guide push plate 20 to reset and maintain the cleaning effect. This improves the adaptability to complex terrain.

[0029] A mixing tank 25 is fixedly installed on the frame 12. A servo motor 26 is installed on the mixing tank 25. A rotating shaft 27 driven by the servo motor 26 is rotatably installed inside the mixing tank 25. A crushing blade 28 is fixedly installed on the rotating shaft 27. An adding tank 29 is installed on the mixing tank 25. A guide tube 30 is installed on the mixing tank 25. During grouting, the cutting waste is fed into the mixing tank 25. The servo motor 26 drives the rotating shaft 27 to rotate the crushing blade 28 at high speed to cut and break up the waste. At the same time, additives can be injected as needed through the addition tank 29. After the materials are mixed evenly in the tank, they are output through the conduit 30 for backfilling of the damaged surface layer, realizing a closed loop of waste-recycled material-repair on-site, eliminating the need to transport waste residue or additional new repair materials.

[0030] The working process of the intelligent road surface repair and reinforcement equipment provided by this invention is as follows: The machine is mounted on a vehicle-mounted connection structure on frame 12 and transported to the road defect site by the vehicle. Upon arrival at the work area, the entire machine is positioned to carry out road defect treatment. The drilling device performs roadbed drilling, forming grouting holes 9 inside the roadbed; the grouting device reuses the same hollow special steel pipe 1, through which grouting reinforcement is carried out deep into the roadbed. The road cutting device performs damaged road surface removal and cleaning. During the operation, the cooling and dust suppression water system simultaneously supplies cooling water to both the drilling and cutting work stations, simultaneously cooling the cutting tools and suppressing dust. The negative pressure waste collection device follows the road cutting operation, collecting road debris generated in real time, completing the entire process of roadbed reinforcement and damaged road surface repair. The equipment achieves integrated operation of multiple working mechanisms, taking into account both transport mobility and the ability to carry out multiple processes simultaneously on site, improving the overall construction efficiency of road defect treatment. Before operation, adjust the multiple sets of telescopic support legs 2 at the bottom of the frame 12, and use the anti-slip support base at the bottom to level the entire machine, eliminating operational deviations caused by uneven ground. The first hydraulic engine 3 outputs rotational and lifting driving force to drive the specially made steel pipe 1 downward feed, rotating and cutting the soil to complete the roadbed drilling. During drilling, roadbed soil samples can be taken to understand the actual working conditions inside the roadbed. The cooling and dust suppression water pipe 4 supplies water to the drilling point to cool the drill bit of the specially made steel pipe 1, while suppressing the rock and soil dust generated during drilling. This ensures the stability of the entire drilling machine, cools the drill bit and suppresses dust while drilling and taking soil, and improves the accuracy of drilling operations and the construction environment. After the roadbed drilling process is completed, the grouting material stored inside the cement storage silo 6 is adjusted by changing the opening of the baffle between the outlet and the special steel pipe 1 to change the grout flow cross section, thereby controlling the grout output flow rate. The prepared cement grout enters the inner cavity of the special steel pipe 1 and flows outward along the multi-layered grouting holes 9 distributed axially along the special steel pipe 1. The grout can fill cavities and soft soil disease areas at different depths in the roadbed. The grout gradually solidifies to achieve deep reinforcement of the roadbed. The grouting flow rate can be flexibly controlled, and the grout is output in layers at multiple points, achieving layered grouting reinforcement of disease areas at different depths in the roadbed. The second hydraulic engine 10 outputs two independent power sources. One power source drives the multi-degree-of-freedom articulated mechanical arm 8 to swing and rotate, thereby adjusting the spatial position and cutting depth of the cutting blade 7 to adapt to the contours of different cracked and collapsed road surfaces. The other power source drives the cutting blade 7 to rotate at high speed. The high-speed rotating cutting blade 7 mills and breaks up the damaged concrete and asphalt layers of the road surface, separating the damaged road surface and creating working conditions for subsequent road repair and cleaning. It flexibly adapts to different damaged road surface shapes, precisely adjusts the cutting position and depth, and efficiently completes the cutting and breaking up of damaged road surfaces. After the operation starts, cooling water is introduced into the cooling and dust suppression water pipe 4. The water flows through the pipe branches to the cutting area of ​​the cutting blade 7 and the drilling point of the special steel pipe 1. The cooling water is sprayed directly onto the cutting position of the cutting blade 7 and the drilling position of the special steel pipe 1. On the one hand, it removes a large amount of heat generated by cutting friction, reducing tool thermal wear; on the other hand, the water mist captures dust particles raised by cutting and drilling, causing the dust to settle and reducing the spread of dust at the construction site. One water system serves two work positions simultaneously, achieving tool cooling and dust suppression at the same time, reducing the need for auxiliary water supply equipment on site. Simultaneously with the road cutting operation, the suction motor 5 is activated. The suction motor 5 operates within the road waste storage bin at the bottom inner side of the frame 12, creating a negative pressure environment. Under this negative pressure, the stone and debris generated during the cutting operation are carried by the airflow and transported through the suction pipe 11, ultimately being sucked into the road waste storage bin for temporary storage. The waste generated during cutting does not require manual on-site cleaning; after all maintenance procedures are completed, the waste inside the storage bin is centrally unloaded and disposed of. Real-time negative pressure collection of cutting debris reduces manual cleaning procedures and lowers the labor intensity of on-site waste cleanup. During the equipment relocation and transportation phase, the telescopic support legs 2 retract, and the entire machine is quickly locked and secured to the cargo box mounting position of the engineering vehicle using the connecting flanges and quick-locking mechanisms arranged on the top and sides of the frame 12, allowing it to be transported with the engineering vehicle. Upon arrival at the repair site, the quick-locking mechanism is unlocked, and the telescopic support legs 2 extend to lift the entire machine, detaching it from the vehicle's cargo box chassis. The equipment then relies on the support legs to stand on the ground and independently carry out all repair work. The equipment can be quickly disassembled and mounted on ordinary engineering vehicles without the need for a dedicated trailer, balancing convenient relocation with independent on-site operation capabilities. When the equipment needs short-distance relocation or fine-tuning, rotating the first threaded adjusting rod 15, with the help of the feed action of the threaded transmission pair, drives the sliding column 14 to slide axially along the inner wall of the mounting cylinder 13, thereby pushing the mounting frame 16 to extend outward, so that the traveling wheels 17 contact the ground to support the entire machine, thus propelling the equipment to complete a short-distance translation. After the relocation is completed, rotating the adjusting rod in the opposite direction retracts the sliding column 14, removes the traveling wheels 17 from the ground, and the equipment returns to its fixed operating state. The threaded transmission has a self-locking characteristic, which can stably maintain the extended and retracted positions of the traveling wheels 17. Small-range positioning adjustments can be completed without relying on engineering vehicles, improving the positional flexibility of the equipment in on-site operations and reducing the difficulty of alignment. Rotating handle 24 drives the second threaded adjusting rod 23 to rotate, pushing the movable plate 18 to slide along the inside of the mounting frame 16, adjusting the extension stroke of the auxiliary wheel 22. During equipment movement, if there are obstacles in the forward direction, the guide push plate 20 will guide the obstacles to both sides to avoid affecting the overall movement of the equipment. If a stubborn obstacle is encountered, the guide push plate 20 will retract into the movable cavity 19 and compress the spring 21 to absorb vibration.
