Description

Technical Field

[0001] This invention relates to the field of highway crack repair technology, and more specifically, to a highway crack repair device for highway maintenance. Background Technology

[0002] Highway crack repair devices are specialized equipment used for road maintenance. They are mainly used to repair various cracks and defects in asphalt and cement concrete pavements. These devices inject repair materials into the cracks to form a sealed and waterproof layer, preventing moisture and debris from entering the cracks and extending the service life of the road.

[0003] Chinese Patent Publication No. CN117071390A discloses a highway crack repair device for traffic engineering, which solves the problems of poor operability and low efficiency in repairing road surface cracks in existing highway crack repair devices for traffic engineering. The device includes a body, a control mechanism, a repair mechanism, and a telescopic mechanism. A rotating shaft is rotatably connected to the body, and a device box is fixedly connected to the bottom end of the rotating shaft. The repair mechanism includes a storage bucket and a shovel plate, and the telescopic mechanism includes a telescopic rod. This highway crack repair device for traffic engineering allows for easy control of the rotation of the device box through the control mechanism and changes in the movement path of the body. The repair mechanism also allows molten asphalt in the storage bucket to be transported into the device box.

[0004] The aforementioned technical solution involves using a shovel to remove the protrusion at the front while simultaneously pushing the asphalt inside the device box towards the central crack. A telescopic mechanism drives a telescopic rod to reciprocate, allowing the corresponding telescopic rod to insert into the crack, thus improving the efficiency of asphalt filling. However, after a road cracks, the cracks are exposed to the outside for extended periods, allowing dust and dirt to enter the cracks. Filling the crack with asphalt at this time results in dust between the filler and the original road material, preventing the filler from fully adhering to the initial road material after solidification, thus affecting the quality of the road crack repair. Furthermore, traditional road crack repair requires manual blowing of a high-pressure air hose into the crack to remove dust and dirt before filling. This manual blowing of the high-pressure hose slows down the dust removal process, further impacting the repair efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a road crack repair device for road maintenance, in order to solve the problems mentioned in the background art above:

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) When using this highway crack repair device for highway maintenance, the V-shaped scraper moves with the telescopic pipe to scrape away the soil on both sides of the crack, preventing dust and soil from re-entering the crack. After multiple air outlets clean the dust inside the crack, the injection pipe injects the filler material into the cleaned crack. The V-shaped gathering plate moves with the injection pipe to gather the injected filler material, allowing the filler material on both sides of the crack to enter the cleaned crack through the V-shaped gathering plate. With the V-shaped scraper in contact with both sides of the road surface, it also serves to smooth the repair material in the cracks. Compared with traditional repair equipment, this repair device can clean the soil in the road cracks. The V-shaped scraper moves with the telescopic pipe to scrape the soil on both sides of the crack away from the crack. The injection pipe injects the filling material into the cleaned crack. The V-shaped scraper moves with the injection pipe to gather and smooth the injected crack filling material. This not only improves the repair quality of highway cracks, but also increases the speed of cleaning dust from highway cracks, thereby improving the repair efficiency of highway cracks.

[0019] 2) When this highway crack repair device is in use, if the crack to be repaired is curved, in order to ensure that the soil in the crack is cleaned, the information collected by the image acquisition device is transmitted to the controller. As the repair equipment moves along the crack line, the controller controls the motor to rotate forward and reverse in real time. The forward and reverse rotation of the motor drives the drive gear to rotate forward and reverse, which in turn causes the driven gear to rotate forward and reverse, causing the two arc-shaped sliders to rotate inside the fixed ring. The rotation of the two arc-shaped sliders causes the two telescopic rods to rotate, which in turn causes the two roller frames to rotate, causing the telescopic tube to rotate inside the air supply pipe. The rotation of the telescopic tube causes the air outlet arc box and multiple air outlet slots to rotate. According to the curvature of the crack, multiple air outlet slots are always facing the crack, and the dust and soil in the crack are cleaned, which increases the functionality and practicality of the equipment.

[0020] 3) When using this highway crack repair device for highway maintenance, in order to more quickly remove the soil on both sides of the crack, the gas inside the air supply pipe enters the telescopic pipe, and part of the gas inside the telescopic pipe enters the connecting air pipe. The gas inside the connecting air pipe enters the two common rail air pipes through the hollow box, and then exits through multiple air blowing pipes. With the movement of the V-shaped scraper, the air blowing from multiple air blowing pipes quickly removes the soil on both sides of the crack, thereby preventing the soil on both sides of the crack from re-entering the crack.

[0032] Example 1: Please refer to Figure 1 - Figure 10A highway crack repair device for highway maintenance includes a repair device 1 that travels along the highway crack. The repair device 1 repairs the highway crack. Two sets of vertical plates 2 are fixedly installed on the surface of the repair device 1. Each set of vertical plates 2 has a matching lifting plate 3 slidably connected to its surface. A movable frame 4 is installed below each of the two lifting plates 3. An air supply pipe 5 and an injection pipe 15 are fixedly installed on the bottom surface of the middle of each movable frame 4. The injection pipe 15 injects injection material into the cleaned crack. The air supply pipe 5 has a telescopic pipe 6 that can slide and rotate. Based on the curvature of the crack, multiple air outlets 8 are always facing the crack to clean dust and dirt from it, increasing the functionality and practicality of the device. The telescopic pipe 6 is sealed and connected to the air supply pipe 5. An air outlet arc box 7, connected to the bottom surface of the telescopic pipe 6, is fixedly installed. The air outlet arc box 7 is designed in a crescent shape, allowing multiple air outlet slots 8 to quickly blow out the dirt from the cracks. Multiple air outlet slots 8 are formed on the outer arc-shaped surface of the air outlet arc box 7. A fixing ring 9 is fixedly installed on the surface of the air supply pipe 5. Matching arc-shaped sliders 10 are slidably connected inside the fixing ring 9. Two roller frames 11 are fixedly installed on the surface of the telescopic pipe 6. A telescopic rod 12 is provided between the arc-shaped sliders 10 and the roller frames 11. The telescopic rod 12 is a conventional telescopic rod 12 in the prior art, and a spring 13 for resetting its movement is sleeved on the surface of the telescopic rod 12. A device for expelling dust is fixedly installed on one side of the telescopic pipe 6. The V-shaped scraper 14, following the movement of the telescopic pipe 6, scrapes away the soil on both sides of the crack away from the road surface crack. A V-shaped gathering plate 16 is fixedly installed on one side of the injection pipe 15 to gather the repair material in the center. The V-shaped gathering plate 16 follows the movement of the injection pipe 15 to gather and flatten the injected repair material. As the repair equipment 1 travels along the crack line, two image acquisition devices 26 also capture images of the crack location in real time. The information collected by the image acquisition devices 26 is transmitted to the controller 34. The controller 34 controls the operation of the two telescopic devices 22 in real time, thereby adjusting the position of the injection pipe 15 and the air outlet arc box 7. When cleaning the crack, the gas inside the air supply pipe 5 enters the telescopic pipe 6 and then passes through the air outlet arc box. Multiple air outlets 8 on the surface of the road surface discharge gas, which blows out dust from the road surface cracks. The blown-out dust and dirt fall to both sides of the road surface cracks. As the repair equipment 1 continues to move along the crack line, the V-shaped scraper 14 moves with the telescopic pipe 6 to scrape away the dirt on both sides of the crack away from the road surface crack, preventing dust and dirt from re-entering the crack. After the multiple air outlets 8 have cleaned the dust inside the crack, when the injection pipe 15 passes through the cleaned crack, the injection pipe 15 injects the injection material into the cleaned crack. The V-shaped gathering plate 16 moves with the injection pipe 15 to gather the injected crack repair material, so that the injection material on both sides of the crack enters the cleaned crack through the V-shaped gathering plate 16.The V-shaped converging plate 16 contacts the road surface on both sides of the crack. The V-shaped converging plate 16 also serves to smooth the repair material. Compared to traditional repair equipment 1, this repair device effectively cleans the soil from the road surface cracks. The V-shaped scraper 14 moves with the telescopic pipe 6, scraping the soil from both sides of the crack away from the crack. The injection pipe 15 injects the filler material into the cleaned crack. The V-shaped converging plate 16 moves with the injection pipe 15, converging and smoothing the injected filler material. This not only improves the quality of highway crack repair but also increases the speed of cleaning dust from the cracks, thus improving the efficiency of highway crack repair. When the crack to be repaired is curved, to ensure the cleanliness of the soil in the crack... The information acquired by the image acquisition device 26 is transmitted to the controller 34. As the repair device 1 travels along the crack line, the controller 34 controls the motor 24 to rotate forward and backward in real time. The forward and reverse rotation of the motor 24 drives the drive gear 25 to rotate in both directions, which in turn causes the driven gear 23 to rotate in both directions, rotating the two arc-shaped sliders 10 inside the fixed ring 9. The rotation of the two arc-shaped sliders 10 causes the two telescopic rods 12 to rotate, which in turn causes the two roller frames 11 to rotate, rotating the telescopic tube 6 inside the air supply pipe 5. The rotation of the telescopic tube 6 causes the air outlet arc box 7 and multiple air outlet slots 8 to rotate. Based on the curvature of the crack, the multiple air outlet slots 8 are always facing the crack, cleaning the dust and dirt in the crack, increasing the functionality and practicality of the equipment.

[0033] A connecting plate 17 is fixedly installed between the telescopic pipe 6 and the V-shaped scraper 14. A connecting plate 2 18 is fixedly connected between the V-shaped gathering plate 16 and the injection pipe 15. The telescopic end of the telescopic rod 12 is fixedly connected to the surface of the roller frame 11, and the other end of the telescopic rod 12 is fixedly connected to the bottom surface of the arc-shaped slider 10. One end of the spring 13 is fixedly connected to the surface of the roller frame 11, and the other end of the spring 13 is fixedly connected to the arc-shaped slider 10. The spring 13 is used for the movement reset of the roller frame 11. The bottom surface of the roller frame 11 is at the same height as the V-shaped scraper 14, ensuring that the movement of the V-shaped scraper 14 scrapes away the soil on both sides of the crack away from the crack on the road surface.

[0034] The bottom surfaces of the two lifting plates 3 are fixedly mounted with fixed slides 19. The surfaces of the two fixed slides 19 are slidably connected with matching slides 20. The bottom surfaces of the two slides 20 are fixedly connected to the top surfaces of the two movable frames 4 respectively. The surfaces of the two fixed slides 19 are fixedly mounted with upright plates 21. The inner surfaces of the two upright plates 21 are fixedly mounted with telescopic devices 22. The telescopic devices 22 are conventional electric push rods in the prior art. The telescopic ends of the two telescopic devices 22 are fixedly connected to the surfaces of the two movable frames 4 respectively. As the repair equipment 1 moves along the crack line, the controller 34 controls the two telescopic devices 22 to work in real time, thereby adjusting the position of the injection pipe 15 and the air arc box 7.

[0035] The bottom surfaces of the two arc-shaped sliders 10 extend to the bottom of the fixed ring 9. The driven gear 23 is fixedly installed on the surface of the two arc-shaped sliders 10. A driving gear 25 that meshes with the driven gear 23 is provided on one side of the driven gear 23.

[0036] A motor 24 is provided above the drive gear 25. The motor 24 is a conventional forward and reverse motor in the prior art. The motor 24 is fixedly installed inside one of the movable frames 4. The output end of the motor 24 is fixedly connected to the surface of the drive gear 25. Image acquisition devices 26 for detecting crack paths are fixedly installed on the inner sides of both movable frames 4. The image acquisition devices 26 are conventional image acquisition devices in the prior art.

[0037] A connecting pipe 27 connected to the air supply pipe 5 is fixedly installed on its surface. A connecting pipe 28 connected to the filling pipe 15 is fixedly installed on its surface. A top plate 29 is fixedly installed on the top surfaces of the two sets of vertical plates 2. An air pump 31 and a storage tank 32 are fixedly installed on the surface of the top plate 29 respectively. The air pump 31 is a conventional air pump 31 in the prior art. The storage tank 32 is a conventional storage device in the prior art. The air outlet of the air pump 31 is sealed to the connecting pipe 27 through a hose. The material outlet of the storage tank 32 is sealed to the connecting pipe 28 through a hose.

[0038] Multiple telescopic devices 30 are fixedly installed on the bottom surface of the top plate 29. The telescopic devices 30 are conventional electrically controlled push rods in the prior art. The telescopic ends of the telescopic devices 30 are fixedly connected to the surface of the lifting plate 3.

[0039] A power supply cabinet 33 is fixedly installed on the end surface of the repair equipment 1. The power supply cabinet 33 is a conventional power supply cabinet 33 in the prior art. A controller 34 is fixedly installed on the surface of the power supply cabinet 33. The controller 34 is a conventional controller 34 in the prior art. The controller 34 is electrically connected to the second expansion joint 30 through wires, the controller 34 is electrically connected to the motor 24 through wires, the controller 34 is electrically connected to the image acquisition device 26 through wires, and the controller 34 is electrically connected to the first expansion joint 22 through wires. The controller 34 receives information collected by the image acquisition device 26 and controls the operation of the second expansion joint 30, the first expansion joint 22, and the motor 24. This is the prior art and will not be described in detail here.

[0040] The usage steps of this invention are as follows: When using this highway crack repair device for highway maintenance, during the crack repair process, the repair equipment 1 is first placed above the crack. Two image acquisition devices 26 capture real-time images of the crack location. The information collected by the image acquisition devices 26 is transmitted to the controller 34. The controller 34 controls the two telescopic devices 22 to operate. The telescopic devices 22 extend and retract, moving two movable frames 4, which in turn move the air supply pipe 5 and the injection pipe 15 above the crack. The controller 34 then controls multiple telescopic devices 30 to extend. The extended telescopic devices 30 respectively move two lifting plates 3 downwards on the surfaces of the two sets of vertical plates 2. The downward movement of the two lifting plates 3 respectively moves the air supply pipe 5 and the injection pipe 15 towards the crack. During the downward movement of the air supply pipe 5, the air supply pipe 5 carries the telescopic pipe 6 and the air outlet arc box 7 downward. The downward movement of the telescopic pipe 6 carries the two roller frames 11 and the V-shaped scraper 14 downward. When the roller surface of the roller frame 11 and the bottom surface of the V-shaped scraper 14 simultaneously contact the road surface on both sides of the crack, as the expansion joint 30 continues to extend, the roller frame 11 is squeezed upward by the bottom surface and moves upward with the telescopic pipe 6. The upward movement of the roller frame 11 compresses the telescopic rod 12, compressing the spring 13. At this time, the multiple air outlet grooves 8 on the outer arc surface of the air outlet arc box 7 are aligned with the crack. During the movement of the injection pipe 15 towards the crack, the V-shaped gathering plate 16 moves downward. When the bottom surface of the V-shaped gathering plate 16 contacts the road surface on both sides of the crack, the expansion joint 30 stops working, and the repair is completed. As the equipment 1 travels along the crack line, two image acquisition devices 26 also capture images of the crack location in real time. The information collected by the image acquisition devices 26 is transmitted to the controller 34. As the repair equipment 1 travels along the crack line, the controller 34 controls the two expansion joints 22 to work in real time, thereby adjusting the position of the injection pipe 15 and the air outlet arc box 7. When cleaning the crack, the air pump 31 works to output high-pressure gas from the air outlet end. The gas then enters the connecting pipe 27 through the hose, and then enters the air supply pipe 5. After the gas in the air supply pipe 5 enters the expansion pipe 6, it is discharged through multiple air outlet slots 8 on the surface of the air outlet arc box 7. The gas discharged from the multiple air outlet slots 8 blows out the dust in the road crack. The blown-out dust and dirt will fall onto the road. As the repair equipment 1 continues to travel along the crack line, the telescopic pipe 6 moves, carrying the connecting plate 17 and the V-shaped scraper 14. The V-shaped scraper 14 scrapes away the soil on both sides of the crack, preventing dust and soil from re-entering the crack. As the repair equipment 1 continues to travel along the crack line, after the multiple air outlets 8 have cleaned the dust inside the crack, the injection pipe 15 passes through the cleaned crack. The repair material inside the storage tank 32 is injected into the cleaned crack through the injection pipe 15. After injection, the injection pipe 15 continues to travel, carrying the connecting plate 18 and the V-shaped gathering plate 16. The V-shaped gathering plate 16 gathers the injected repair material.The filling material on both sides of the crack enters the cleaned crack through the V-shaped gathering plate 16. The V-shaped gathering plate 16 contacts the road surface on both sides of the crack and also serves to smooth the crack repair material. When the crack to be repaired is curved, in order to ensure that the soil in the crack is cleaned, the information collected by the image acquisition device 26 is transmitted to the controller 34. As the repair equipment 1 moves along the crack line, the controller 34 controls the motor 24 to rotate forward and reverse in real time. The forward and reverse rotation of the motor 24 drives the drive gear 25 to rotate forward and reverse, which in turn causes the driven gear 23 to rotate forward and reverse, causing the two arc-shaped sliders 10 to rotate inside the fixed ring 9. The rotation of the two arc-shaped sliders 10 causes the two telescopic rods 12 to rotate, which in turn causes the two roller frames 11 to rotate, causing the telescopic tube 6 to rotate inside the air supply pipe 5. The rotation of the telescopic tube 6 causes the air outlet arc box 7 and multiple air outlet slots 8 to rotate. According to the curvature of the crack, the multiple air outlet slots 8 are always facing the crack, thus cleaning the dust and soil in the crack.

[0041] Compared to traditional repair equipment 1, this repair device enables the cleaning of soil from road surface cracks. The V-shaped scraper 14 moves with the telescopic pipe 6 to scrape the soil on both sides of the crack away from the crack. The injection pipe 15 injects the injection material into the cleaned crack. The V-shaped gathering plate 16 moves with the injection pipe 15 to gather and flatten the injected crack repair material. This not only improves the repair quality of highway cracks but also increases the speed of cleaning dust from the cracks, thereby improving the repair efficiency. Furthermore, according to the curvature of the crack, multiple air outlets 8 are always facing the crack to clean the dust and soil in the crack, increasing the functionality and practicality of the equipment.

[0042] Example 2: Please refer to Figure 1 - Figure 10 The difference from Embodiment 1 is that both V-shaped surfaces of the V-shaped scraper 14 have slots 35 inside, and common rail air pipes 36 are fixedly installed inside both slots 35. Multiple air blowing pipes 37 connected to the common rail air pipes 36 are fixedly installed on the surface of each common rail air pipe 36, and the bottom ends of the multiple air blowing pipes 37 protrude from the surface of the V-shaped scraper 14. The gas discharged from the multiple air outlets 8 blows the dust out of the road surface cracks. The blown dust and dirt fall to both sides of the road surface cracks. The movement of the V-shaped scraper 14 moves the sides of the cracks... The soil is scraped away from the sides of the crack. In order to clear the soil from the sides of the crack more quickly, the gas inside the air supply pipe 5 enters the telescopic pipe 6. A portion of the gas inside the telescopic pipe 6 enters the connecting air pipe 39. The gas inside the connecting air pipe 39 enters the two common rail air pipes 36 through the hollow box 38, and then exits through multiple air blowing pipes 37. With the movement of the V-shaped scraper 14, the air blowing pipes 37 quickly clear the soil from the sides of the crack, thus preventing the soil from re-entering the crack.

[0043] The top surfaces of the two common rail air tubes 36 are fixedly installed with a hollow box 38 that communicates with them. A connecting air tube 39 is fixedly installed between the hollow box 38 and the telescopic tube 6, and the two ends of the connecting air tube 39 are respectively sealed and connected to the telescopic tube 6 and the hollow box 38.

[0044] The steps of using this invention are as follows: When using this highway crack repair device for highway maintenance, the gas discharged from multiple air outlets 8 blows out the dust in the road surface cracks. The blown-out dust and dirt fall to both sides of the road surface cracks. The movement of the V-shaped scraper 14 scrapes the dirt on both sides of the cracks away from the cracks. In order to clean the dirt on both sides of the cracks more quickly, after the gas inside the air supply pipe 5 enters the telescopic pipe 6, part of the gas inside the telescopic pipe 6 enters the connecting air pipe 39. The gas inside the connecting air pipe 39 enters the two common rail air pipes 36 through the hollow box 38, and then exits through multiple air blowing pipes 37. With the movement of the V-shaped scraper 14, the air blowing pipes 37 quickly clean the dirt on both sides of the cracks, thereby preventing the dirt on both sides of the cracks from re-entering the cracks.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
