Description

Technical Field

[0001] This invention relates to the field of road repair cutting technology, and in particular to a cutting device for repairing round or elliptical holes in road surfaces. Background Technology

[0002] In existing road maintenance, circular or irregular potholes are typically repaired using a "round hole, square patch" method. This involves first widening the original pothole into a rectangular area manually or with a handheld cutting tool, then filling it with asphalt mixture and compacting it. While this method is simple to operate, it has the following significant drawbacks:

[0003] Significant material waste: To facilitate subsequent filling, it is often necessary to enlarge the original pothole area, resulting in unnecessary road damage and waste of asphalt materials;

[0004] Poor repair quality: Due to irregular edges or deviations in cutting angles, cracks are prone to occur at the joints between new and old pavements, affecting the lifespan of the repair.

[0005] Lack of targeted design: There are currently relatively few specialized devices for efficient cutting of circular or elliptical grooves;

[0006] Safety concerns: Splinters fly during the cutting process, posing a safety hazard;

[0007] Severe dust pollution: The large amount of dust generated by dry cutting not only affects air quality but also endangers the health of construction workers;

[0008] Equipment overheating issue: Prolonged high-intensity cutting operations can easily cause the blade temperature to rise, affecting its service life and cutting accuracy;

[0009] Poor maneuverability: Traditional equipment struggles to maintain a stable trajectory when cutting through complex terrain or curves. To address this, we propose a cutting device for repairing round or elliptical holes in road surfaces. Summary of the Invention

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] Example 1

[0037] Reference Figure 1-6A cutting device for repairing round or elliptical holes in road surfaces includes a machine housing 1, a support part 2, and a walking track 3. The support part 2 is fixed to the bottom of the machine housing 1, and the walking track 3 is provided at the bottom of the support part 2. A cutting mechanism is assembled at one end of the machine housing 1. The cutting mechanism includes a movable arm 4, an extension arm 5, a through-hole 6, a movable mounting frame 7, and a transmission component. A through-hole 6 is provided at one end of the machine housing 1. The movable arm 4 is assembled inside the through-hole 6 and is clearance-fitted with the through-hole 6. An extension arm 5 is detachably connected to one end of the movable arm 4. A movable mounting frame 7 is assembled at one end of the extension arm 5, and a transmission component is assembled inside the movable mounting frame 7.

[0038] The transmission assembly includes a motor 8, a rotating shaft 9, and a cutting disc 10. The motor 8 is fixed to one side of the movable mounting frame 7, and the rotating shaft 9 is rotatably connected to the inner side of the movable mounting frame 7. The output end of the motor 8 is fixed to the rotating shaft 9, and the cutting disc 10 is fixed to the outer side of the rotating shaft 9. The cutting disc 10 is clearance-fitted with the inner side of the movable mounting frame 7. When the motor 8 is started, the output end of the motor 8 drives the rotating shaft 9 to rotate, which in turn drives the cutting disc 10 to rotate, cutting the road surface that needs to be repaired.

[0039] A lifting mechanism is installed between the machine housing 1 and the movable arm 4. The lifting mechanism is used to adjust the position of the cutting disc 10. The lifting mechanism includes a transmission rod 11, a first hydraulic rod 12, a mounting beam 13, a U-shaped plate 15, and a second hydraulic rod 16. The transmission rod 11 is rotatably connected to both sides of the machine housing 1, and the first hydraulic rod 12 is rotatably connected to the top of each transmission rod 11. A mounting beam 13 is rotatably connected to the output ends of the two first hydraulic rods 12. The mounting beam 13 is fixed to the movable arm 4, and both ends of the mounting beam 13 are rotatably connected to the transmission rod 11. U-shaped plates 15 are rotatably connected to both sides of the machine housing 1 and above the transmission rods 11. The second hydraulic rod 16 is rotatably connected to the inner side of the U-shaped plate 15. The output ends of the second hydraulic rod 16 are rotatably connected to the mounting beam 13. When the second hydraulic rod 16 is activated, its output ends pull the mounting beam 13. Because the mounting beam 13 is rotatably connected to the transmission rod 11, and the transmission rod 11 is rotatably connected to the machine housing 1, the mounting beam 13 can drive the movable arm 4 and the extension arm 5 to rotate, thereby adjusting the position and angle of the cutting disc 10.

[0040] The lifting mechanism also includes tie plates 14. Both ends of the top of the mounting beam 13 are integrally fixed with tie plates 14. One end of each tie plate 14 is fixed to the movable arm 4. The tie plates 14 make the connection between the movable arm 4 and the mounting beam 13 more secure and stable, preventing the movable arm 4 from tipping over.

[0041] An adjustment mechanism is installed between the extension arm 5 and the movable mounting frame 7. The adjustment mechanism includes an end housing 17, a third hydraulic rod 18, a positioning rod 20, and a guide wheel 21. The end of the extension arm 5 away from the movable arm 4 is fixed with the end housing 17. The third hydraulic rod 18 is rotatably connected to the inner side of the end housing 17. The output end of the third hydraulic rod 18 is rotatably connected to the movable mounting frame 7. One end of the movable mounting frame 7 is rotatably connected to the end housing 17. The positioning rod 20 is fixed to the side of the movable mounting frame 7 away from the motor 8. One end of the positioning rod 20 is rotatably connected to the guide wheel 21. When it is necessary to adjust the cutting depth of the cutting disc 10, the third hydraulic rod 18 is activated, causing the output end of the third hydraulic rod 18 to pull the movable mounting frame 7 to rotate, thereby causing the movable mounting frame 7 to drive the inner cutting disc 10 to change position and achieve the adjustment of the cutting depth.

[0042] A controller 23 is fixed to one end of the top of the bearing part 2, and an image recognition positioning module 19 is fixed to the bottom of the end housing 17. The image recognition positioning module 19 is electrically connected to the controller 23, and the controller 23 is electrically connected to the motor 8, the first hydraulic rod 12, the second hydraulic rod 16, and the third hydraulic rod 18. Through the setting of the image recognition positioning module 19 and the controller 23, it is convenient to identify the potholes or repair locations on the road surface, and to intelligently control the start and stop of the motor 8, the first hydraulic rod 12, the second hydraulic rod 16, and the third hydraulic rod 18, so as to achieve precise cutting operations.

[0043] Example 2

[0044] Further optimizations to Example 1, specifically, such as... Figure 2 and Figure 5 As shown, a water spray dust suppression mechanism is installed on the inner side of the machine housing 1. This mechanism is used to suppress dust during the cutting process of the cutting disc 10. The water spray dust suppression mechanism includes a water tank 22, a water pump 24, an inlet pipe 25, an outlet pipe 26, a connecting hose 27, a support column 28, a metal pipe 29, and a nozzle 30. The water tank 22 is fixed to the inner side of the machine housing 1. The water pump 24 is fixed to one side of the water tank 22. The inlet pipe 25 is fixed to the input end of the water pump 24, and one end of the inlet pipe 25 is fixed to the water tank 22. The outlet pipe 26 is fixed to the output end of the water pump 24, and a connecting hose 27 is fixed to one end of the outlet pipe 26. The support column 28 is fixed to the top of the end housing 17. A metal pipe 29 is fixed to the inner side of the support column 28. One end of the metal pipe 29 is fixed to the connecting hose 27, and the other end of the metal pipe 29 is fixed to the nozzle 30. When the water pump 24 is started, the input end of the water pump 24 transmits the water in the water tank 22 to the outlet pipe 26. After passing through the connecting hose 27 and the metal pipe 29, the water is finally sprayed onto the cutting disc 10 through the nozzle 30 to reduce the dust generated during cutting and avoid affecting the working environment. The spray direction of the nozzle 30 is set towards the direction close to the cutting disc 10.

[0045] In summary:

[0046] This invention addresses the following technical problems: In existing road maintenance, circular or irregular potholes are typically repaired using a "round hole, square patch" method. This involves first widening the original pothole into a rectangular area manually or with a handheld cutting tool, then filling it with asphalt mixture and compacting it. While this method is simple to operate, it has the following significant drawbacks: Significant material waste: To facilitate subsequent filling, the original pothole area often needs to be enlarged, leading to unnecessary road surface damage and asphalt material waste; Poor repair quality: Due to irregular edges or cutting angle deviations, cracks easily form at the joint between the old and new road surfaces, affecting the repair's lifespan; Lack of targeted design: Currently, there are relatively few specialized devices for efficiently cutting circular or elliptical potholes; Insufficient safety: Splashing debris during cutting poses a safety hazard; Severe dust pollution: The large amount of dust generated by dry cutting not only affects air quality but also endangers the health of construction workers; Equipment overheating: Prolonged high-intensity cutting operations can easily cause the blade temperature to rise, affecting its lifespan and cutting accuracy; Poor operational flexibility: Traditional equipment struggles to maintain a stable trajectory when cutting complex terrain or curves. The invention adopts the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0047] During use, when cutting is required, the motor 8 is started. The output end of the motor 8 drives the rotating shaft 9 to rotate, which in turn drives the cutting disc 10 to rotate and cut the uneven road surface. When the position of the cutting disc 10 needs to be adjusted, the second hydraulic rod 16 is started, which pulls the mounting beam 13. Because the mounting beam 13 is rotatably connected to the transmission rod 11, and the transmission rod 11 is rotatably connected to the machine housing 1, the mounting beam 13 can drive the movable arm 4 and the extension arm 5 to rotate, thereby adjusting the position and angle of the cutting disc 10.

[0048] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0049] 1. Through the structural design of the cutting mechanism, image recognition positioning module 19 and controller 23, this invention enables the device to automatically identify and cut out a circular or elliptical area that matches the original pit, avoiding over-cutting. Circular cutting helps to enhance the adhesion between new and old materials, extend the repair life, reduce unnecessary cutting area, reduce the amount of asphalt used, and improve construction efficiency.

[0050] 2. Through the structural design of the lifting mechanism and the adjustment mechanism, this invention enables the device to adapt to asphalt layers of different thicknesses, thereby improving the applicability of the equipment. With the auxiliary guidance of the guide wheel 21, the accuracy of the cutting path is significantly improved.

[0051] 3. By equipping the machine housing 1, the present invention can effectively prevent debris from injuring people. By setting up the water spray dust suppression mechanism, it can significantly reduce dust pollution, improve the construction environment, and at the same time prevent the cutting disc 10 from deforming or being damaged due to high temperature, thus extending its service life.
