Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] Please see Figures 1-7 The grooving machine 100 according to an embodiment of the present invention includes a grooving assembly 20 and a tractor body 10, wherein the grooving assembly 20 is disposed on the tractor body 10. The grooving assembly 20 is adapted to be fixed on the tractor body 10. For example, the grooving assembly 20 can be connected and fixed on the tractor body 10 by means of fasteners such as bolts, snap-fit, or welding. The tractor body 10 can be any type of engineering vehicle. Optionally, the tractor body 10 is provided with a position alignment device 28, which can be an infrared aligner. The infrared aligner can be disposed at the rear of the tractor body 10 and can be used to locate the position of a pit. For example, when the infrared aligner is aligned with the pit, it indicates that the position of the cutting head 2320 is aligned with the position of the pit.

[0031] The grooving assembly 20 includes a first support 21, a second support 22, a cutting head 23, and a rotary drive device 25. The first support 21 is adapted to be rotatably connected to the support platform so that the first support 21 can be in a folded state relative to the support platform (e.g., Figures 1-2 (as shown in the image) and the deployment state relative to the supporting platform (as shown in the image) Figures 3-6 The second support 22 is connected to the first support 21 and can move relative to the first support 21. When the first support 21 is in the unfolded state, the second support 22 can move up and down relative to the first support 21 to make it in the raised state (as shown in the diagram). Figures 3-4 (as shown in the image) and the decentralization state (as shown in the image) Figures 5-6 The cutting head 23 is connected to the second support 22 and can rotate relative to the second support 22. When the second support 22 is in the lowered state, the cutting head 23 can be pushed forward to be in contact with the ground. The rotary drive device 25 is connected to the cutting head 23 to drive the cutting head 23 to rotate. Optionally, the rotary drive device 25 can be a rotary motor, which can be located inside the cutting head 23.

[0032] Specifically, when a pothole appears on the road, the grooving assembly 20 is quickly moved to the site by the towing vehicle 10. Once the infrared aligner at the rear of the towing vehicle 10 is aligned with the pothole, the first bracket 21 is moved from... Figures 1-2 The folded state shown is flipped to Figures 3-4 The second support 22 is then deployed as shown in the diagram. Figures 3-4 The elevation state shown has been moved to Figures 5-6 The lowered state shown in the figure allows the cutting head 23 to be pushed into contact with the ground, and then the cutting head 23 is driven to rotate by the rotary drive device 25 to cut the road surface.

[0033] According to the embodiment of this utility model, the grooving component 20 can be folded and stacked onto the tractor body 10 when not in use, facilitating rapid relocation and enabling rapid grooving. This addresses the current pain points of long repair times, low efficiency, and high risks associated with pothole repair. Furthermore, when the rotary motor drives the cutting head 23 to rotate and cut, the tractor body 10 and the frame of the grooving component 20 remain stationary, resulting in minimal vibration and high precision during equipment operation.

[0034] It should be noted that in some examples, the support platform can be part of the tractor body 10, that is, it can be formed by part of the tractor body 10 (such as the floor of the carriage); in other examples, please refer to [reference needed]. Figures 1-6 The slotted assembly 20 may also include a support plate 24, which forms a support platform. A first bracket 21 is connected to the support plate 24, and then the support plate 24 is connected to the tractor body 10, thereby realizing the connection between the slotted assembly 20 and the tractor body 10.

[0035] Optionally, a locking structure 29 is provided between the first bracket 21 and the tractor body 10 to lock the first bracket 21 in a folded state. The locking structure 29 can be a pin-type locking structure (e.g., Figures 1-2 (as shown), or a snap-locking structure, etc.

[0036] Please see Figures 1-6 The slotted assembly 20 also includes a first drive device 26, which is connected between the support platform and the first bracket 21 to drive the first bracket 21 to rotate relative to the support platform. Optionally, the first drive device 26 is a hydraulic drive device, comprising a first hydraulic cylinder 261 and a first piston rod 262. The first piston rod 262 is disposed within the first hydraulic cylinder 261 and is extendable / retractable relative to the first hydraulic cylinder 261. One of the first hydraulic cylinder 261 and the first piston rod 262 is rotatably connected to the first bracket 21, and the other is rotatably connected to the support platform. Under hydraulic drive, the first piston rod 262 extends / retracts relative to the first hydraulic cylinder 261, thereby driving the first bracket 21 to flip relative to the support platform to switch between a folded state and an unfolded state. In some other embodiments, the first drive device 26 may also be an electric lead screw, etc.

[0037] Please continue reading. Figures 1-6 The slotted assembly 20 also includes a second drive device 27, which is connected between the first bracket 21 and the second bracket 22 to drive the second bracket 22 to move relative to the first bracket 21, thereby driving the second bracket 22 in a raised state (e.g., Figures 3-4 (as shown in the image) and the decentralization state (as shown in the image) Figures 5-6Switching between (as shown in the diagram). Further, the second drive device 27 is a hydraulic drive device, comprising a second hydraulic cylinder 271 and a second piston rod 272. The second piston rod 272 is disposed within the second hydraulic cylinder 271 and is extendable / retractable relative to the second hydraulic cylinder 271. One of the second hydraulic cylinder 271 and the second piston rod 272 is connected to the first bracket 21, and the other is connected to the second bracket 22. Under hydraulic drive, the second piston rod 272 extends / retracts relative to the second hydraulic cylinder 271, thereby driving the second bracket 22 in a raised state (e.g., as shown in the diagram). Figures 3-4 (as shown in the image) and the decentralization state (as shown in the image) Figures 5-6 Switching between (as shown in the diagram). In some other embodiments, the second drive device 27 may also be an electric lead screw, etc.

[0038] Optionally, one of the second hydraulic cylinder 271 and the second piston rod 272 is hinged to the first bracket 21, and the other of the second hydraulic cylinder 271 and the second piston rod 272 is hinged to the second bracket 22. This can reduce the damage to the grooving assembly 20 caused by cutting vibration.

[0039] Please see Figures 1-6 The grooving assembly 20 also includes multiple retractable support legs 30. These support legs 30 are all connected to the second support 22 and are spaced apart circumferentially along the cutting head 23. When the second support 22 is in the lowered position, the support legs 30 can extend to support the ground. By providing multiple retractable support legs 30, a stable support effect can be achieved for the system when the cutting head 23 is cutting. Optionally, the support legs 30 can be hydraulic or electric support legs, etc.

[0040] Please see Figure 6 The cutting head 23 has multiple cutting teeth 232 on its cutting surface 231, which are evenly distributed circumferentially on the cutting surface 231. The cutting teeth 232 protrude downwards from the cutting surface 231. By providing cutting teeth 232 on the cutting surface 231, the cutting teeth 232 serve to rotate and fix the cutting action. As the cutting depth increases, the stability of the grooving area is improved, making the grooving process stable and less prone to movement. Optionally, the cutting teeth 232 and the cutting surface 231 can be integrally formed, meaning they are machined as a single piece. This results in high connection strength between the cutting teeth 232 and the cutting surface 231, making them less prone to breakage. Of course, in other embodiments, the cutting teeth 232 and the cutting surface 231 can also be separate structural components, with the cutting teeth 232 machined separately and then welded to the cutting surface 231. This simplifies the production mold of the cutting head 23.

[0041] Please see Figure 6 and Figure 7The first support 21 is provided with a movable guide post 211, and the second support 22 is provided with a movable guide sleeve 221. The movable guide post 211 is movably inserted into the movable guide sleeve 221. When the second drive device 27 drives the second support 22 to move relative to the first support 21, the movable guide post 211 and the movable guide sleeve 221 also move relative to each other. The movable guide post 211 and the movable guide sleeve 221 play a role in guiding the movement, so that the movement of the second support 22 relative to the first support 21 is smooth and reliable.

[0042] In summary, and in combination with Figures 1-6 When road surface grooving is required, the support plate 24 is bolted to the rear of the tractor body 10. Then, the grooving assembly 20 is moved to the grooving position at the repair site by the tractor body 10. The infrared alignment device is turned on to determine the working position. Then, the generator and hydraulic pump station drive the first drive device 26 to flip the cutting head 23 to the rear of the vehicle. At this time, the cutting head 23 is at a 90-degree angle to the ground. Then, the second drive device 27 and the balance support leg 30 work together to push the cutting surface 231 of the cutting head 23 into contact with the ground. Then, the rotary motor works to drive the cutting head 23 to rotate and cut. By making the cutting teeth 232 on the outer ring of the cutting head 23 slightly protrude from the cutting teeth of the cutting surface 231, it plays a role in positioning and stabilizing the operation process. During the operation of the cutting head 23, the cutting marks overlap each other, leaving no blind spots. The broken asphalt or concrete debris from grooving is automatically discharged outward.

[0043] When performing trenching operations, the trenching component 20 of this application allows the operator to control various parts of the equipment by turning on the generator and controlling the valves through the oil circuit. By utilizing the functional mechanisms of each part for rapid control, it enables rapid trenching of ground pits and rapid evacuation. It has the advantages of flexible relocation, fast operation speed and high efficiency, and reduces the workload of trenching personnel.

[0044] According to a second aspect of the present invention, a grooving machine 100 includes a grooving component 20 and a traction vehicle body 10, wherein the grooving component 20 is disposed on the traction vehicle body 10.

[0045] The grooving machine 100 according to the present invention has all the advantages of the grooving component 20 according to the first aspect embodiment of the present invention, which will not be repeated here.
