Description

Technical Field

[0001] This application relates to the field of road repair technology, and in particular to a grouting device for repairing road cracks. Background Technology

[0002] With the rapid development of highway construction, the task of highway maintenance has also become more demanding. Crack sealing of asphalt and cement concrete pavements is one of the key tasks in preventive maintenance. Crack sealing adhesive is mainly used to repair road cracks.

[0003] Chinese Patent CN218345918U discloses a grouting device for road crack repair, which includes a base plate, a grouting machine box fixedly connected to the top of the base plate, a fixed box fixedly connected to one side of the grouting machine box, a cement pump fixedly installed inside the fixed box, a suction pipe inserted into the suction end of the cement pump, the other end of the suction pipe located inside the grouting machine box, a discharge pipe inserted into the discharge end of the cement pump, and a grouting device fixedly connected to one side of the base plate.

[0004] The aforementioned technology involves injecting repair grout into cracks using a cement pump under pressure. However, road surface cracks are typically irregularly shaped and extend into the interior of the road, where they also exhibit irregular bending. Since the repair grout usually has a certain viscosity, as it penetrates deeper into the road, air chambers are formed within the deeper cracks. This prevents subsequent injections of repair grout from flowing further into the deeper cracks, resulting in the deep cracks remaining unrepaired. Consequently, the road subsequently cracks again during its use, highlighting its shortcomings. Utility Model Content

[0005] To address the problem that repair grout cannot flow into deep cracks inside highways, this application provides a grouting device for road crack repair.

[0006] The grouting equipment for road crack repair provided in this application adopts the following technical solution:

[0007] A grouting device for road crack repair includes a trolley and a vibrating frame. The trolley is equipped with a dust removal component and a grouting assembly. The dust removal component is used to clean dust from the road cracks, and the grouting assembly is used to inject repair grout into the cleaned road cracks. The vibrating frame is equipped with a plurality of vibrating hoses, one end of which is inserted into a deep crack in the road surface. The vibrating frame is equipped with a vibrating element that drives the vibrating hoses to vibrate.

[0008] By adopting the above technical solution, the dust removal component first removes the dust accumulated in the road surface cracks. Then, the workers insert several vibrating hoses into the deep cracks of the road surface in sequence. After that, the workers inject repair grout into the road surface cracks through the grouting component. At the same time, the vibrating component causes the vibrating hoses to vibrate. Under the guidance of the vibrating hoses, the repair grout will flow along the vibrating hoses into the deep cracks of the road surface, thereby achieving the repair effect on the deep cracks of the road surface and reducing the possibility of secondary cracks in the road surface.

[0009] Optionally, the dust removal component includes a fan mounted on the trolley, the fan being electrically connected to the control system, the fan having an air outlet hose at its outlet end, and an air outlet nozzle at the end of the air outlet hose facing away from the fan.

[0010] By adopting the above technical solution, workers hold the air nozzle and aim it at the road surface cracks. The control system starts the blower, and the blower delivers high-speed airflow to the air nozzle through the air outlet hose. The high-speed airflow cleans the cracks, thereby reducing the dust in the cracks and improving the repair effect of the repair grout on the road surface cracks.

[0011] Optionally, the trolley is equipped with a placement column and a nozzle tube. The placement column is equipped with a tube rod with an L-shaped cross-section. The air outlet hose is hung on the tube rod, and the air outlet nozzle is inserted into the nozzle tube.

[0012] By adopting the above technical solution, when the air outlet nozzle is not in use, workers can hang the air outlet hose on the pipe support rod and insert the air outlet nozzle into the nozzle support tube, thereby reducing the possibility of the air outlet nozzle falling off during the movement of the cart.

[0013] Optionally, the grouting assembly includes a grout storage tank, a grout supply nozzle, a grout supply pump, and a lifting cylinder mounted on the trolley. The grout storage tank contains repair grout. The grout supply pump and the lifting cylinder are both electrically connected to the control system. The grout supply nozzle is mounted on the piston rod of the lifting cylinder. Grout supply hoses are provided between the grout supply nozzle and the grout supply pump, and between the grout supply pump and the grout storage tank.

[0014] By adopting the above technical solution, after the vibrating hose is inserted into the deep cracks in the road surface, the worker starts the lifting cylinder through the control system. The piston rod of the lifting cylinder drives the grout supply nozzle to be close to the top of the road surface crack. Then the control system starts the grout supply pump. The grout supply pump delivers the repair grout in the storage tank to the road surface crack through the grout supply hose. At the same time, the worker pushes the cart along the trend of the road surface crack, thereby repairing the road surface crack.

[0015] Optionally, the vibrating element includes an impact plate slidably disposed on the vibrating frame. The vibrating frame has a groove for the impact plate to slide back and forth. A vibrating block is slidably disposed on the groove of the vibrating frame. The impact plate is used to impact the vibrating block. A compression spring supports the side of the vibrating block facing away from the impact plate and the groove. A drive motor electrically connected to the control system is disposed on the vibrating frame. A rocker arm is disposed on the output shaft of the drive motor. The length direction of the rocker arm is perpendicular to the axis of the output shaft of the drive motor. A connecting rod is hinged between the rocker arm and the impact plate.

[0016] By adopting the above technical solution, when the grout supply nozzle delivers repair grout to the road surface cracks, the control system starts the drive motor. The output shaft of the drive motor drives the rocker arm to rotate. The rocker arm drives the impact plate to slide back and forth on the chute through the connecting rod. During the sliding process of the impact plate, the impact plate continuously impacts the vibrating block. The vibrating block compresses the compression spring, and the compression spring deforms. Then, it pushes the vibrating block to slide in the opposite direction again. The vibrating block sliding in the opposite direction will collide with the impact plate again, thereby generating vibration of the vibrating frame. The vibration on the vibrating frame will be transmitted to the vibrating hose, so that the vibrating hose can vibrate the repair grout in the deep cracks of the road surface, thereby improving the repair effect of deep cracks in the road surface.

[0017] Optionally, an impact column is vertically slidably mounted on the vibration frame, and an impact hammer is mounted at the bottom of the impact column for impacting the ground. A drive shaft coaxial with the output shaft of the drive motor is rotatably mounted on the vibration frame. A bridge rod is mounted on the drive shaft, and a connecting column is mounted between the bridge rod and the rocker arm. The axis of the connecting column is away from the axis of the drive shaft. A connecting rod is rotatably connected to the connecting column. A lifting plate is mounted on the end of the drive shaft facing away from the bridge rod. A horizontal support plate is mounted on the impact column, and the lifting plate is used to push the support plate to slide vertically.

[0018] By adopting the above technical solution, during the rotation of the output shaft of the drive motor, the rocker arm drives the bridge rod to rotate synchronously through the connecting column. The bridge rod drives the lifting plate to rotate continuously through the drive shaft. During the rotation of the lifting plate, the lifting plate will push the support plate to rise. The support plate drives the impact column to rise synchronously until the lifting plate separates from the support plate. Under the action of gravity, the impact column drives the impact hammer to impact the area around the crack in the road surface, thereby allowing the repair slurry injected into the crack to spread more quickly to the deeper cracks in the road surface, which is conducive to further improving the repair effect of road surface cracks.

[0019] Optionally, a tension spring is provided between the top of the impact column and the top of the vibration frame.

[0020] By adopting the above technical solution, the tension spring is stretched during the upward movement of the impact column. When the lifting plate separates from the support plate, the tension spring recovers its deformation. Under the action of the tension spring, the impact column drives the impact hammer to quickly impact the area around the crack in the road surface, thereby improving the vibration effect at the crack in the road surface.

[0021] Optionally, the bottom of the vibration frame is provided with a rubber plate, and the side of the rubber plate facing the ground is roughened.

[0022] By adopting the above technical solution, the rubber plate can increase the friction between the vibrating frame and the road surface during the vibration process, thereby reducing the possibility of the vibrating frame moving during the vibration process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The dust removal unit first removes the dust accumulated in the road surface cracks. Then, the workers insert several vibrating hoses into the deep cracks of the road surface in sequence. After that, the workers inject repair grout into the cracks of the road surface through the grouting component. At the same time, the vibrating unit causes the vibrating hoses to vibrate. Under the guidance of the vibrating hoses, the repair grout will flow along the vibrating hoses into the deep cracks of the road surface, thereby achieving the repair effect on the deep cracks of the road surface and reducing the possibility of secondary cracks in the road surface.

[0025] 2. When the grout supply nozzle delivers repair grout to the road surface cracks, the control system starts the drive motor. The output shaft of the drive motor drives the rocker arm to rotate. The rocker arm drives the impact plate to slide back and forth on the chute through the connecting rod. During the sliding process of the impact plate, the impact plate continuously impacts the vibrating block. The vibrating block will compress the compression spring. The compression spring will deform and then push the vibrating block to slide in the opposite direction. The vibrating block sliding in the opposite direction will collide with the impact plate again, thereby generating vibration of the vibrating frame. The vibration on the vibrating frame will be transmitted to the vibrating hose, so that the vibrating hose can vibrate the repair grout in the deep cracks of the road surface, thereby improving the repair effect of the deep cracks in the road surface.

[0026] 3. During the rotation of the output shaft of the drive motor, the rocker arm drives the bridge rod to rotate synchronously through the connecting column. The bridge rod drives the lifting plate to rotate continuously through the drive shaft. During the rotation of the lifting plate, the lifting plate will push the support plate to rise. The support plate drives the impact column to rise synchronously until the lifting plate separates from the support plate. Under the action of gravity, the impact column drives the impact hammer to impact the area around the crack in the road surface, thereby allowing the repair slurry injected into the crack to spread more quickly to the deeper cracks in the road surface, which is conducive to further improving the repair effect of the road surface cracks.

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] This application discloses a grouting device for repairing road cracks.

[0033] Reference Figure 1 A grouting device for road crack repair includes a trolley 2 and a vibrating frame 3. A rubber sheet 19, which may be made of rubber material, is adhered to the bottom of the vibrating frame 3. The side of the rubber sheet 19 facing the ground is roughened. The trolley 2 is equipped with a dust removal component 4 and a grouting assembly 5. The dust removal component 4 is used to clean dust from the road crack 1, and the grouting assembly 5 is used to inject repair grout into the cleaned road crack 1.

[0034] Reference Figure 1 and Figure 2 The dust removal component 4 includes a fan 41 bolted to the trolley 2. The fan 41 is electrically connected to the control system. The air outlet end of the fan 41 is connected to an air outlet hose 42. The end of the air outlet hose 42 facing away from the fan 41 is connected to an air outlet nozzle 43. A placement column 8 and a nozzle holder 9 are bolted to the trolley 2. A placement rod 10 with an L-shaped cross-section is welded to the placement column 8. The air outlet hose 42 is hung on the placement rod 10. The air outlet nozzle 43 is inserted into the nozzle holder 9.

[0035] The worker holds the air nozzle 43 and aims it at the crack on the road surface. Then, the blower 41 is started through the control system. The blower 41 delivers high-speed airflow to the air nozzle 43 through the air outlet hose 42. The high-speed airflow cleans the dust in the crack, thereby achieving the effect of removing dust from the road surface crack 1.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The grouting assembly 5 includes a grout storage tank 51, a grout supply nozzle 52, a grout supply pump 53, and a lifting cylinder 54 arranged on the trolley 2. The grout storage tank 51 is filled with repair grout. The grout supply pump 53 and the lifting cylinder 54 are both electrically connected to the control system. An installation plate 20 is bolted to the piston rod of the lifting cylinder 54. The grout supply nozzle 52 is bolted to the installation plate 20. A grout supply hose 55 connects the grout supply nozzle 52 to the grout supply pump 53 and the grout supply pump 53 to the grout storage tank 51.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Several vibrating hoses 6 are attached to the vibrating frame 3. The vibrating hoses 6 can be made of rubber material. The end of the vibrating hose 6 facing away from the vibrating frame 3 is inserted into a deep crack in the road surface. The vibrating frame 3 is equipped with a vibrating element 7 that drives the vibrating hoses 6 to generate vibration. The vibrating element 7 includes an impact plate 71 that is slidably arranged on the vibrating frame 3. The vibrating frame 3 is provided with a groove 72 for the impact plate 71 to slide back and forth.

[0038] Reference Figure 1 and Figure 2 Vibration blocks 73 are slidably arranged on the slide groove 72 of the vibration frame 3. The impact plate 71 is used to impact the vibration blocks 73. A compression spring 74 supports the side of the vibration block 73 facing away from the impact plate 71 and the slide groove 72. A drive motor 75 electrically connected to the control system is bolted to the vibration frame 3. A rocker arm 76 is welded to the output shaft of the drive motor 75. The length direction of the rocker arm 76 is perpendicular to the axis of the output shaft of the drive motor 75. A connecting rod 77 is hinged between the rocker arm 76 and the impact plate 71.

[0039] Reference Figure 1 , Figure 2 and Figure 3 An impact column 11 is vertically slidably arranged on the vibration frame 3. A tension spring 18 is arranged between the top of the impact column 11 and the top of the vibration frame 3. An impact hammer 12 is welded to the bottom of the impact column 11. The impact hammer 12 can be made of steel. The impact hammer 12 is used to impact the ground. A drive shaft 13 coaxial with the output shaft of the drive motor 75 is rotatably connected to the vibration frame 3. A bridge rod 14 is welded to the drive shaft 13.

[0040] Reference Figure 1 , Figure 2 and Figure 3A connecting post 15 is welded between the bridge rod 14 and the rocker arm 76. The axis of the connecting post 15 is away from the axis of the drive shaft 13. The connecting rod 77 is rotatably connected to the connecting post 15. A lifting plate 16 is welded to the end of the drive shaft 13 facing away from the bridge rod 14. A horizontal support plate 17 is bolted to the impact post 11. The lifting plate 16 is used to push the support plate 17 to slide vertically.

[0041] Then, the workers inserted several vibrating hoses 6 into the deep cracks in the road surface in sequence. At the same time, the workers started the lifting cylinder 54 through the control system. The piston rod of the lifting cylinder 54 drove the grout supply nozzle 52 to gradually approach the crack in the road surface through the mounting plate 20. Then, the control system started the grout supply pump 53. The grout supply pump 53 delivered the repair grout in the storage tank 51 to the crack in the road surface 1 through the grout supply hose 55. At the same time, the workers pushed the cart 2 along the trend of the crack in the road surface 1 and ensured that the grout supply nozzle 52 was directly above the crack.

[0042] During the process of injecting repair grout into the crack through the grout supply nozzle 52, the control system starts the drive motor 75. The output shaft of the drive motor 75 drives the rocker arm 76 to rotate. The rocker arm 76 drives the impact plate 71 to reciprocate on the slide groove 72 through the connecting column 15 and the connecting rod 77. During the sliding process of the impact plate 71, the impact plate 71 continuously impacts the vibrating block 73. Under the action of the reaction force, the vibrating block 73 will compress the compression spring 74.

[0043] After the compression spring 74 deforms and recovers its deformation, the recovered compression spring 74 pushes the vibrating block 73 to slide in the opposite direction again. The vibrating block 73 that slides in the opposite direction will collide with the impact plate 71 again, so that the vibrating frame 3 will continuously vibrate. The vibration on the vibrating frame 3 will be transmitted to the vibrating hose 6, so that the vibrating hose 6 can vibrate the repair slurry in the deep cracks of the road surface.

[0044] The connecting column 15 drives the drive shaft 13 to rotate via the bridge rod 14. The drive shaft 13 drives the lifting plate 16 to rotate synchronously. The rotating lifting plate 16 pushes the support plate 17 to rise. The support plate 17 drives the impact column 11 and the impact hammer 12 to rise synchronously.

[0045] During this process, the tension spring 18 is stretched until the lifting plate 16 separates from the support plate 17, and the tension spring 18 returns to its deformation. At the same time, under the gravity of the impact column 11 and the impact hammer 12, the impact hammer 12 will quickly impact the area around the road surface crack 1, thereby causing vibration around the crack, which facilitates the possibility of the repair grout flowing to the deeper cracks in the road surface.

[0046] The implementation principle of a grouting device for road crack repair in this application embodiment is as follows: the worker holds the air nozzle 43 and aims it at the crack on the road surface, and then starts the fan 41 through the control system. The fan 41 delivers high-speed airflow to the air nozzle 43 through the air outlet hose 42. The high-speed airflow cleans the dust in the crack, thereby achieving the effect of removing dust from the road crack 1.

[0047] Then, the workers inserted several vibrating hoses 6 into the deep cracks in the road surface in sequence. At the same time, the workers started the lifting cylinder 54 through the control system. The piston rod of the lifting cylinder 54 drove the grout supply nozzle 52 to gradually approach the crack in the road surface through the mounting plate 20. Then, the control system started the grout supply pump 53. The grout supply pump 53 delivered the repair grout in the storage tank 51 to the crack in the road surface 1 through the grout supply hose 55. At the same time, the workers pushed the cart 2 along the trend of the crack in the road surface 1 and ensured that the grout supply nozzle 52 was directly above the crack.

[0048] During the process of injecting repair grout into the crack through the grout supply nozzle 52, the control system starts the drive motor 75. The output shaft of the drive motor 75 drives the rocker arm 76 to rotate. The rocker arm 76 drives the impact plate 71 to reciprocate on the slide groove 72 through the connecting column 15 and the connecting rod 77. During the sliding process of the impact plate 71, the impact plate 71 continuously impacts the vibrating block 73. Under the action of the reaction force, the vibrating block 73 will compress the compression spring 74.

[0049] After the compression spring 74 deforms and recovers its deformation, the recovered compression spring 74 pushes the vibrating block 73 to slide in the opposite direction again. The vibrating block 73 that slides in the opposite direction will collide with the impact plate 71 again, so that the vibrating frame 3 will continuously vibrate. The vibration on the vibrating frame 3 will be transmitted to the vibrating hose 6, so that the vibrating hose 6 can vibrate the repair slurry in the deep cracks of the road surface.

[0050] The connecting column 15 drives the drive shaft 13 to rotate via the bridge rod 14. The drive shaft 13 drives the lifting plate 16 to rotate synchronously. The rotating lifting plate 16 pushes the support plate 17 to rise. The support plate 17 drives the impact column 11 and the impact hammer 12 to rise synchronously.

[0051] During this process, the tension spring 18 is stretched until the lifting plate 16 separates from the support plate 17, and the tension spring 18 returns to its deformation. At the same time, under the gravity of the impact column 11 and the impact hammer 12, the impact hammer 12 will quickly impact the area around the road surface crack 1, thereby causing vibration around the crack, which facilitates the possibility of the repair grout flowing to the deeper cracks in the road surface.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
