Description

Technical Field

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

[0002] If road cracks are not repaired in time, the combined effects of water and load will lead to more serious structural damage to the asphalt pavement, severely reducing the integrity, safety and driving comfort of the asphalt pavement. In particular, for pavements with more severe cracks, it is necessary to clean and repair the inside of the cracks in time.

[0003] For example, a Chinese patent discloses "A Road Repair Device" (patent number: CN114481777B). This patent includes a first road surface detection device that acquires first road surface information and sends this information to a cleaning device via a control device. The cleaning device cleans the determined repair location of the road surface based on the first road surface information and sends a notification message indicating that cleaning is complete to a second road surface detection device via the control device. After receiving the notification message, the second road surface detection device acquires second road surface information and sends it to the control device. The control device determines the repair location of the road surface based on the second road surface information and generates control commands. A robotic arm, according to the control commands, transports asphalt repair blocks to the repair location of the road surface and performs the road repair operation. This patent has the advantage of improving the efficiency of road repair.

[0004] However, in the above-mentioned repair process, due to the relatively simple cleaning device, it is difficult to effectively clean the contaminants deep in the crack and at the bottom of the crack. Therefore, the contaminants remaining in the crack after repair will have a significant impact on the repair quality, resulting in a low repair quality. Summary of the Invention

Detailed Implementation

[0027] This invention provides a road crack cleaning and repair device, such as... Figure 1-6 As shown, it includes a main body 11, a first slot 12, a bracket 13, a grouting machine 14, a grouting pipe 15, an electric wire 16, a drive power supply 17, a first slider 18, an electric push rod main rod 19, an electric push rod secondary rod 20, a second slot 21, a conveyor belt 22, a drive shaft 23, a third slot 24, a connecting seat 25, a connecting rod 26, a detection rod 31, a fourth slot 32, a main hook 33, a first opening 34, a first spring 35, a second opening 36, a rotating rod 37, a secondary hook 38, a trigger cavity 40, a trigger end 41, a trigger base 42, and a second spring 43.

[0028] like Figure 1-6 As shown, a first slot 12 is provided in the main body 11, and a first slider 18 is slidably disposed in the first slot 12. A telescopic component is fixedly connected to the first slider 18. A probe rod 31 is fixedly connected to the end of the telescopic component away from the main body 11. A dirt fixing mechanism is provided at the end of the probe rod 31 away from the main body 11. The dirt fixing mechanism includes a trigger component and several hook components. The trigger component is used to trigger the hook components. Several fourth slots 32 are provided on the outer circular surface of the probe rod 31. A trigger cavity 40 is provided at the end of the probe rod 31 away from the main body 11. The trigger component is disposed in the trigger cavity 40. The hook components are rotatably connected to the fourth slots 32.

[0029] It is worth noting that the first slot 12 is a T-shaped slot, and the shape and size of the first slider 18 are adapted to the first slot 12.

[0030] The telescopic assembly includes an electric push rod main rod 19 and an electric push rod secondary rod 20. The electric push rod main rod 19 is slidably connected to the electric push rod secondary rod 20. The electric push rod main rod 19 is electrically connected to a wire 16 through a first slot 12. A drive power supply 17 is fixedly installed on the main body 11 and is electrically connected to the wire 16. A grouting machine 14 is fixedly connected to the main body 11. A grouting pipe 15 is fixedly installed at one end of the grouting machine 14. Both the grouting machine 14 and the grouting pipe 15 are existing technologies.

[0031] The hook assembly includes a main hook 33 and a first spring 35. The main hook 33 is rotatably connected to a fourth slot 32. A first opening 34 and a second opening 36 are provided in the fourth slot 32. One end of the first spring 35 is fixedly connected to one end face of the first opening 34, and the other end of the first spring 35 is fixedly connected to the main hook 33. Rotating rods 37 are fixedly connected to both sides of the main hook 33. The rotating rods 37 are rotatably connected to the second opening 36. The first opening 34 is inclinedly arranged in the fourth slot 32 and extends in the direction of the main hook 33. Several fourth slots 32 are distributed with equal arcs around the axis of the probe rod 31.

[0032] It is worth noting that when the triggering component does not trigger the hook component, the main hook 33 is located in the fourth slot 32 and is in a vertical state, and the first spring 35 is compressed in the first opening 34 by the main hook 33.

[0033] The trigger assembly includes a trigger end 41 and a trigger base 42. The trigger end 41 is slidably connected to the trigger cavity 40. A second spring 43 is fixedly connected to one end of the trigger cavity 40 near the main body 11. The second spring 43 is fixedly connected to the trigger base 42. The trigger base 42 is fixedly connected to the trigger end 41. A slot is provided on the side of the trigger base 42 near the trigger end 41. A secondary hook 38 is provided on the main hook 33. A locking block is provided on the secondary hook 38. The locking block of the secondary hook 38 is adapted to the slot of the trigger end 41.

[0034] It is worth noting that the top of the fourth slot 32 is connected to the trigger cavity 40.

[0035] Second slots 21 are provided on both sides of the first slot 12. Two drive shafts 23 are rotatably connected in the second slots 21. A conveyor belt 22 is fitted on the outer circumference of the drive shafts 23. A third slot 24 is provided on the side of the first slider 18 near the conveyor belt 22. A connecting seat 25 is rotatably provided in the third slot 24. A connecting rod 26 is fixedly connected to the connecting seat 25. The connecting rod 26 is rotatably connected to one side wall of the third slot 24. The conveyor belt 22 is fixedly connected to the connecting seat 25.

[0036] It is worth noting that the drive shaft 23 is connected to a drive source, which is used to drive the drive shaft 23 to rotate relative to the second slot 21, thereby causing the drive shaft 23 to drive the conveyor belt 22 to rotate in the second slot 21. Since the conveyor belt 22 is fixedly connected to the connecting seat 25, the conveyor belt 22 drives the connecting seat 25 to translate in the first slot 12, so that the connecting seat 25 drives the first slider 18 to translate in the first slot 12 through the connecting rod 26, thereby achieving the purpose of enabling the detection rod 31 and the claw assembly to translate in the crack, and better assisting the claw assembly to clean the dirt in the crack.

[0037] When this solution is used for cleaning and repairing road cracks, first, the device is set up directly above the road crack, and the detection rod 31 is aligned with the crack. The drive power supply 17 is turned on. The drive power supply 17 controls the electric push rod main rod 19 to push out the electric push rod secondary rod 20 through the wire 16. The electric push rod secondary rod 20 drives the detection rod 31 into the crack.

[0038] Then, when the trigger end 41 in the probe rod 31 contacts the bottom of the crack, the trigger end 41 slides towards the second spring 43 and compresses the second spring 43. The trigger end 41 drives the trigger base 42 to slide upward, thereby separating the slot of the trigger base 42 from the block of the secondary hook 38. The first spring 35 pushes the main hook 33 to rotate outward around the rotating rod 37 as the axis. The main hook 33 rotates to a horizontal state or rotates until the end of the main hook 33 away from the rotating rod 37 is in close contact with the crack wall.

[0039] Next, the drive shaft 23 rotates, driving the conveyor belt 22 to rotate. The conveyor belt 22 drives the connecting seat 25 to move horizontally within the first slot 12. The connecting seat 25 drives the first slider 18 to move horizontally within the first slot 12 via the connecting rod 26. This causes the detection rod 31 and the hook assembly to move horizontally within the crack, gripping the dirt in the crack. The electric push rod main rod 19 pulls the electric push rod secondary rod 20 back towards the electric push rod main rod 19, thereby cleaning out the dirt from the crack.

[0040] Finally, the grouting pipe 15 is inserted into the bottom of the crack to inject repair grout, thus completing the repair.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
