Technical Field

[0001] This invention belongs to the field of road repair technology, and in particular relates to a flattening repair device and method for road repair. Background Technology

[0002] With the increasing speed and quality of highway construction, asphalt pavement has become widely used. However, joints and cracks that appear during the paving and use of asphalt pavement usually require the use of pavement repair equipment. After the repair, the gaps are flattened. However, due to poor cleaning of the gaps and poor adhesive application, the repair agent does not adhere tightly to the pavement. When flattening after filling the repair agent, the repair effect of the repair agent on the gaps cannot be guaranteed. At the same time, the existing repair equipment is usually complex in structure, and the different construction operations of cleaning, applying adhesive, and flattening the pavement cracks are cumbersome, which also affects the efficiency of compaction repair work.

[0019] A method for flattening and repairing road surfaces, based on the aforementioned flattening and repairing equipment for road surface repair, further includes the following steps:

[0020] S1. Move the vehicle body to the area to be repaired by using the casters at the front and the handle at the rear.

[0021] S2. Cutting gaps: Align the cutting end of the cutting piece with the gap in the road surface, and use the lifting mechanism to extend the cutting end into the gap.

[0022] S3, transmission cleaning component: When the lifting component raises and lowers the cutting end, the lifting component drives the cleaning roller to rise and fall to clean the area to be cut.

[0024] S5. Compact the crack: Move the vehicle body to allow the flattening roller to pass through the repair and adhesive application area.

[0025] Compared with the prior art, the present invention has the following advantages and technical effects:

[0026] This invention features a cutting component with a liftable cutting end at the front of the vehicle body. After the vehicle body is moved to the area to be repaired, the cutting end is lowered and inserted into the road surface to cut the gaps to be repaired, making the inner wall of the gaps flat. This facilitates the adhesion of the repair agent to the gaps after application. When the cutting end is raised and lowered, a cleaning roller is driven to rise and fall along with it via a transmission component. This allows the cleaning roller to clean the gaps during cutting, preventing impurities from entering the cuts and affecting subsequent repairs. When not cutting, the cleaning roller also rises with the cutting component, avoiding interference with the vehicle's normal movement and allowing for the flattening of the road surface. This not only reduces the workload for workers but also effectively improves construction efficiency. When applying adhesive to the cut gaps, the blower's air outlet blows out dust and impurities from the gaps and helps the sprayed repair agent dry quickly. Finally, a flattening roller moves to the repair area to flatten the repair agent. The flattening roller is equipped with a pressure-applying component to effectively increase pressure, ensuring that the repaired gaps are flush with the original road surface and improving the repair effect.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example: Refer to Figures 1-6 A flattening and repair device for road surface repair, comprising,

[0038] Vehicle body 1;

[0039] A cutting component is provided at the front end of the vehicle body 1, and the cutting component has a cutting end that can be raised or lowered relative to the vehicle body 1.

[0040] The cleaning component includes a cleaning roller 2 disposed at the front end of the cutting end. One end of the cleaning roller 2 is connected to a transmission component, which is connected to the cutting end. The cleaning roller 2 can be rotated and raised relative to the vehicle body 1 through the cooperation of the transmission component and the cutting end. When the cutting end extends into the road surface, the cleaning roller 2 slides in contact with the road surface.

[0041] A coating component is located at the rear end of the cutting end. A blower 4 is installed between the coating component and the cutting end, with the air outlet of the blower 4 facing the coating component and the cutting end respectively.

[0042] A flattening component is located at the rear end of the adhesive-coated component. The flattening component includes a flattening roller 5 that is connected to the vehicle body 1. A pressure-applying component is provided on the flattening roller 5. The pressure-applying component is an eccentric oscillating structure.

[0043] This invention features a cutting component with a liftable cutting end at the front end of the vehicle body 1. After the vehicle body 1 is moved to the area to be repaired, the cutting end is lowered and inserted into the road surface to cut the gaps to be repaired, making the inner wall of the gaps flat. This facilitates the adhesion of the repair agent to the gaps after the adhesive is applied. When the cutting end is raised and lowered, a cleaning roller 2 is driven to rise and fall together via a transmission component. This allows the cleaning roller 2 to clean the gaps during cutting, preventing impurities from entering the cuts and affecting subsequent repairs. When not cutting, the cleaning roller 2 is raised along with the cutting component, avoiding interference with the normal movement of the vehicle body 1 for flattening the road surface. This not only reduces the tediousness of the workers' operations but also effectively improves construction efficiency. When applying adhesive to the cut gaps, the air outlet of the blower 4 blows out dust and impurities from the gaps and helps the sprayed repair agent to dry quickly. Finally, a flattening roller 5 moves to the repair area to flatten the repair agent. The flattening roller 5 is equipped with a pressure-applying component to effectively increase the pressure, ensuring that the repaired gaps are flush with the original road surface and improving the repair effect.

[0044] In this technical solution, the vehicle body 1 is moved by using the universal wheel 38 at the front end and the handle 39 at the rear end. It can be understood that the universal wheel 38 is at the bottom of the vehicle body 1 and the handle 39 is at the top of the vehicle body 1, which facilitates the movement of the workers. The entire road surface crack repair process is completed by using the cleaning roller 2, cutting component, blower 4, adhesive application component and flattening roller 5 arranged in sequence at the bottom of the vehicle body 1 along the repair sequence.

[0045] Furthermore, a lifting component is provided at the front end of the vehicle body 1, and a cutting component is provided on the movable end of the lifting component. The transmission component includes a transmission rod 3 with one end connected to the vehicle body 1 and the other end of the transmission rod 3 being connected to the movable end. The transmission rod 3 rotates and rises relative to the vehicle body 1. The cleaning roller 2 is provided on the transmission rod 3 and connected to the transmission rod 3. A reset component is provided between the transmission rod 3 and the vehicle body 1.

[0046] The lifting component drives the cutting component to rise and fall. At the same time, the movable end of the lifting component can drive the transmission rod 3 and the vehicle body 1 to rotate and rise during the lifting process. The cleaning roller 2 is connected to the transmission rod 3, so that when the cutting component cuts the gap, the cleaning roller 2 slides into contact with the road surface to clean the gap. When the lifting component lifts the cutting component, the reset component acts on the transmission rod 3 to rotate and lift the transmission rod 3 together with the cleaning roller 2, avoiding cumbersome operation steps and speeding up the construction efficiency.

[0047] Furthermore, the lifting component includes two fixed plates 6 fixedly connected to the top of the vehicle body 1, a top plate 7 fixedly connected between the two fixed plates 6, one end of a hydraulic cylinder 8 is provided at the bottom of the top plate 7, and a first support plate 9 is fixedly connected to the other end of the hydraulic cylinder 8. The first support plate 9 is in a limiting sliding contact with the fixed plate 6. Two lifting plates 15 are fixedly connected to the bottom of the first support plate 9. A through groove is opened at the top of the vehicle body 1 corresponding to the lifting plate 15. The lifting plate 15 slides through the through groove and is in contact with the vehicle body 1. The number of transmission rods 3 is the same as that of the lifting plates 15 and they correspond one-to-one. A lever 16 is fixedly connected to the outer wall of the lifting plate 15. The end of the transmission rod 3 away from the vehicle body 1 is inclined toward the lever 16, and the lever 16 slides in contact with the transmission rod 3.

[0048] Reference Figure 2 , Figure 5 One end of the hydraulic cylinder 8 is set on the top plate 7 and fixed relative to the top plate 7. By starting the hydraulic cylinder 8, the first support plate 9 is driven to slide along the fixed plate 6. The fixed plate 6 has a corresponding groove for the first support plate 9, and a limit post 10 is fixed in the groove. The first support plate 9 has a limit groove corresponding to the limit post 10 to realize the limit sliding connection of the first support plate 9. The first support plate 9 drives the lifting plate 15 to slide. During the lifting process of the lifting plate 15, the lever 16 contacts the transmission rod 3 and continuously presses down the transmission rod 3, thereby driving the cleaning roller 2 to rise and fall.

[0049] In one embodiment of the present invention, a clamping groove is provided on the top plate 7, and two clamping seats 14 are slidably connected in the clamping groove. A clamping plate 11 is fixed to the top of the clamping seat 14. The clamping plate 11 passes through the top plate 7 and is slidably connected to the top plate 7. A screw 12 is passed through the two clamping plates 11. The screw 12 is rotatably fixed to one of the clamping plates 11, and the screw 12 is threadedly connected to the other clamping plate 11. One end of the screw 12 extends out of the two clamping plates 11 and is threadedly connected to a nut 13. By rotating the nut 13 and then rotating the screw 12, the clamping plate 11 threadedly connected to the screw 12 and the other clamping plate 11 move in opposite directions or towards each other, thereby moving the clamping seat 14 to clamp and fix the hydraulic cylinder 8.

[0050] Furthermore, the cutting component includes a cutting blade 17 disposed between two lifting plates 15. A connecting rod 18 is fixedly connected to the axis of the cutting blade 17. Both ends of the connecting rod 18 extend into the two lifting plates 15 and are connected to the lifting plates 15 respectively. A drive motor 19 is fixedly connected to the outer wall of one of the lifting plates 15 on one side of the lever 16. The output shaft of the drive motor 19 is fixedly connected to the connecting rod 18.

[0051] A support rod 20 is fixedly connected to the transmission rod 3. The support rod 20 is set obliquely downward on the side away from the lever 16. The cleaning roller 2 is set between the two support rods 20. The two ends of the cleaning roller 2 extend into the two support rods 20 and are connected to the support rods 20 respectively. A rotating motor 21 is fixedly connected to the outer wall of one of the support rods 20. The output shaft of the rotating motor 21 is fixedly connected to the cleaning roller 2.

[0052] When the lifting plate 15 raises and lowers the cutting blade 17, the drive motor 19 is started to rotate the connecting rod 18 to drive the cutting blade 17 to cut the seam. At the same time, when the lifting plate 15 descends, the lever 16 presses the transmission rod 3. The transmission rod 3 and the vehicle body 1 rotate and descend, causing the cleaning roller 2 located on the support rod 20 to slide into contact with the road surface. The rotating motor 21 is started to clean the seam area.

[0053] Furthermore, the reset component includes two second support plates 22 fixedly connected to the bottom of the vehicle body 1, a support rod 23 fixedly connected between the two second support plates 22, and a collar 24 rotatably sleeved on the support rod 23. The number of collars 24 is the same as that of the transmission rods 3 and they correspond one-to-one. The collars 24 are fixedly connected to the transmission rods 3, and the two ends of the torsion springs 25 are fixedly connected between the collars 24 and the adjacent second support plates 22 respectively.

[0054] When the lifting plate 15 raises the cutting blade 17, the torsion spring 25 causes the collar 24 to rotate relative to the second support plate 22, thereby raising the transmission rod 3 along with the cleaning roller 2.

[0055] Furthermore, the adhesive application component includes an adhesive application box 26 fixedly attached to the top of the vehicle body 1. A pressure pump 27 is provided on one side of the adhesive application box 26. The inlet end of the pressure pump 27 is connected to the adhesive application box 26, and at least two spray nozzles 28 are connected to the outlet end of the pressure pump 27. The spray nozzles 28 are mounted on a support base 29, which is fixedly attached to the bottom of the vehicle body 1.

[0056] Furthermore, the port shapes of the two spray nozzles 28 are respectively one of circular, V-shaped, Y-shaped, and straight, and the port shapes of the two spray nozzles 28 are different.

[0057] By fixing a support base 29 to the bottom of the vehicle body 1, the outlet end of the pressure pump 27 is connected to the glue spray head 28 through a connecting pipe, as shown in the figure. Figures 1-2 The two spray nozzles 28 are respectively circular and V-shaped. The V-shaped spray nozzle 28 is fixed to the bottom of the support base 29, and the circular spray nozzle 28 is fixed to the front of the support base 29. The recess of the V-shaped spray nozzle 28 is specifically set to correspond to the circular spray nozzle 28. When the pressure pump 27 squeezes the repair agent, the circular spray nozzle 28 sprays the atomized spray into the gap, while the V-shaped spray nozzle 28 fills the edge of the sprayed area. This effectively improves the spraying effect and enhances the adhesion of the repair agent to the gap when repairing the cut. In this patent, cracks, cuts, and gaps are all areas of the road surface to be repaired and are only used to refer to different states of the road surface to be repaired when the repair equipment is in operation.

[0058] In one embodiment of the present invention, a power distribution box 40 is fixedly connected to one side of the glue coating box 26. The power distribution box 40 provides rotational power to the cutting blade 17, the pressure pump 27 and the cleaning roller 2. At the same time, the temperature generated by the power distribution box 40 during operation can act on the glue coating box 26 to prevent the repair agent from solidifying.

[0059] Furthermore, the flattening roller 5 has a multi-layer structure, including an inner ring plate 501 and an outer ring plate 502. At the bottom end of the vehicle body 1, two third support plates 32 are fixedly connected to each other at the rear end of the adhesive coating part. The inner ring plate 501 is disposed on the two third support plates 32 and is interchangeable with the third support plates 32. The pressure applying part is disposed inside the inner ring plate 501 and is interchangeable with the inner ring plate 501. A counterweight block 503 is fixedly connected between the inner ring plate 501 and the outer ring plate 502.

[0060] Furthermore, each of the two third support plates 32 has a connecting seat 33 fixedly connected to its close end. One end of the connecting seat 33 extends into the inner ring plate 501 and is provided with a bearing 34. The inner ring of the bearing 34 is fixedly connected to the connecting seat 33, and the outer ring of the bearing 34 is fixedly connected to the inner wall surface of the inner ring plate 501. The force-applying component includes a servo motor 35 fixedly connected to a connecting seat 33. One end of a rotating rod 36 is fixedly connected to the output shaft of the servo motor 35. The other end of the rotating rod 36 is rotatably connected to another connecting seat 33. An eccentric block 37 is fixedly connected to the rotating rod 36 and is rotatably connected to the inner ring plate 501.

[0061] Reference Figure 4 The moving vehicle 1 drives the flattening roller 5 to flatten and compact the repaired cracks. The servo motor 35 is started to drive the rotating rod 36 to rotate. The rotating rod 36 drives the eccentric block 37 to rotate. During the rotation of the eccentric block 37, the centrifugal mass generated by the eccentric block 37 is unevenly distributed on the inner ring plate 501 of the flattening roller 5. When the outer ring plate 502 squeezes the repair agent at the road crack, the weight generated by the eccentric block 37 acts on the repair agent periodically and intermittently. This causes the end face of the repair agent in the area to be squeezed by external force on the basis of the original compaction by the counterweight block 503, which helps to improve the effect and efficiency of the repair agent being flush with the road surface.

[0062] A method for flattening and repairing road surfaces, based on the aforementioned flattening and repairing equipment for road surface repair, further includes the following steps:

[0063] S1. Move vehicle 1 to the area to be repaired by using the casters 38 at the front end and the handle 39 at the rear end of vehicle 1.

[0064] S2. Cutting gaps: Align the cutting end of the cutting piece with the gap in the road surface, and use the lifting mechanism to extend the cutting end into the gap.

[0065] S3, transmission cleaning component: when the lifting component raises and lowers the cutting end, the lifting component drives the cleaning roller 2 to raise and lower to clean the area to be cut.

[0066] S4. Apply adhesive to the gaps and let it air dry. After the cutter cuts the gaps, apply adhesive to the gaps through the adhesive applicator. At the same time, blower 4 moves towards the adhesive applicator to let the repair agent used to repair the road surface air dry.

[0067] S5. Compact the crack. Move the vehicle body 1 so that the flattening roller 5 passes through the repair adhesive area. Use the pressure application device to provide gravity pressure to the flattening roller 5 so that the repair gap is flush with the original road surface, and the road repair is completed.
