Description

Technical Field

[0001] This utility model relates to the field of road surface repair technology, specifically to a road repair device. Background Technology

[0002] Municipal roads bear a huge volume of traffic and are subjected to frequent vehicle traffic and natural environmental erosion, resulting in frequent potholes. If these potholes are not repaired in time, they will not only accelerate the wear and tear on vehicle parts and affect driving comfort, but may also cause safety accidents.

[0003] Currently, road repair relies heavily on manual labor. First, debris is collected and backfilled into potholes, then filler material is laid. However, manual repair lacks precision, making it difficult to ensure the flatness and uniformity of the backfill and filler material. This results in uneven surfaces, insufficient compaction of the filler material, unsatisfactory repair results, and potholes easily recurring in the short term. Furthermore, manual repair is inefficient, consumes a large amount of manpower and time, and is physically demanding.

[0004] With the advancement of urbanization and the continuous increase in road mileage, higher demands are placed on the efficiency and quality of road repair. Traditional manual repair methods can no longer meet the needs, making the development of efficient, intelligent, and convenient road repair devices an urgent priority. This is of great significance for ensuring the safety and smooth flow of urban road traffic. Utility Model Content

[0005] The purpose of this invention is to provide a road repair device capable of repairing road potholes, thereby improving repair efficiency and ensuring repair results.

[0006] To achieve the above objectives, this application provides a road repair device, comprising: a frame, a support platform, a power unit, and a repair head.

[0007] The frame has a clearance opening on its front side, which extends through the upper and lower surfaces of the frame. A support platform is located above the clearance opening and is fixedly connected to the frame. The support platform and the frame define an operating space.

[0008] The power assembly includes a hydraulic station, a hydraulic cylinder, and hydraulic pipelines. The hydraulic station is fixedly installed on the frame. Both ends of the hydraulic pipelines are connected to the hydraulic cylinder and the hydraulic station, respectively. The hydraulic cylinder is fixedly installed on the support platform. The power output end of the hydraulic cylinder is positioned directly opposite the clearance opening. The repair head is detachably connected to the power end of the hydraulic cylinder. The hydraulic cylinder is used to drive the repair head to reciprocate up and down within the operating space, thereby repairing the ground directly opposite the clearance opening.

[0009] As a preferred technical solution, the repair head is a tamping plate for compacting ground fill or a compacting block for crushing ground gravel.

[0010] As a preferred technical solution, the frame also includes pulleys, which are installed at the bottom of the frame.

[0011] As a preferred technical solution, the frame also includes a push rod, which is fixedly installed on the rear side of the frame.

[0012] As a preferred technical solution, the outer peripheral wall of the support platform is provided with multiple observation ports that connect to the operating space.

[0013] As a preferred technical solution, it also includes ribs, which are located on the outer periphery of the support platform and are fixedly connected to the support platform and the frame, respectively.

[0014] As a preferred technical solution, the power assembly further includes a connector, which is fixedly connected to the power end of the hydraulic cylinder, and the repair head is detachably connected to the power end of the hydraulic cylinder through the connector.

[0015] As a preferred technical solution, the support platform and the frame, the hydraulic station and the frame, and the hydraulic cylinder and the support platform are all connected by bolts.

[0016] The road repair device provided by the above technical solution has the following advantages compared with the prior art: When using the road repair device of this application to repair potholes, the frame must first be moved above the pothole, and the clearance opening on the frame must be aligned with the pothole. A repair head is installed on the power end of the hydraulic cylinder. The hydraulic station is started to drive the power end of the hydraulic cylinder to move, and simultaneously drive the repair head to move up and down in the operating space to crush the stones in the pothole, and then flatten the crushed stones. Subsequently, workers only need to lay asphalt filler on the crushed stones, and then start the hydraulic cylinder to drive the repair head to compact and flatten the asphalt filler in the pothole, thus completing the pothole repair. This device can evenly crush and backfill stones into the pothole, and can compact the asphalt filler, ensuring the flatness of the pothole after the asphalt filler is laid, ensuring the flatness of the road surface after repair. It is also simple and convenient to operate, effectively reducing manpower, improving repair efficiency, and ensuring repair results. Attached Figure Description

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] Please see Figure 1-2 The road repair device provided in this application includes: a frame 1, a support platform 2, a power unit 3, and a repair head 4.

[0031] The frame 1 has a clearance opening 11 on its front side, which extends through the upper and lower surfaces of the frame 1. The support platform 2 is located above the clearance opening 11 and is fixedly connected to the frame 1. The support platform 2 and the frame 1 define an operating space 21.

[0032] The power assembly 3 includes a hydraulic station 31, a hydraulic cylinder 32, and a hydraulic pipeline 33. The hydraulic station 31 is fixedly installed on the frame 1. The two ends of the hydraulic pipeline 33 are respectively connected to the hydraulic cylinder 32 and the hydraulic station 31. The hydraulic cylinder 32 is fixedly installed on the support platform 2. The power output end of the hydraulic cylinder 32 is positioned facing the clearance opening 11. The repair head 4 is detachably connected to the power end of the hydraulic cylinder 32. The hydraulic cylinder 32 is used to drive the repair head 4 to move up and down reciprocally within the operating space 21, thereby repairing the ground facing the clearance opening 11.

[0033] In this embodiment, during actual use, the device is moved to the pothole, and the clearance opening 11 on the frame 1 is aligned with the pothole. The repair head 4 is installed on the power end of the hydraulic cylinder 32. The hydraulic cylinder 32 is started to drive the repair head 4 to move up and down reciprocally within the operating space 21 to crush the stones in the pothole. After all the stones are crushed, the repair head 4 is used to backfill the crushed stone into the pothole and flatten it. Then, asphalt filler is manually laid into the pothole, and the hydraulic cylinder 32 is started again to drive the repair head 4 to compact the asphalt filler and flatten the pothole, thus completing the pothole repair. Compared with traditional manual repair, using this device to repair road potholes is more conducive to ensuring repair efficiency and quality, and ensures that the repaired road is flat, greatly saving manpower.

[0034] It is worth noting that the hydraulic station 31 in this application specifically includes a motor, an oil tank, an oil pump, and control valves. When the hydraulic station 31 is started, the motor drives the oil pump to rotate, and the oil pump draws hydraulic oil from the oil tank, pressurizes it, and outputs it. The hydraulic oil passes through various control valves, such as relief valves, pressure reducing valves, and directional valves, to regulate its pressure, flow rate, and direction. When the hydraulic oil enters the hydraulic cylinder 32 from the hydraulic station 31 through the hydraulic pipeline 33, under the action of the hydraulic oil pressure, the piston at the power end of the hydraulic cylinder 32 is subjected to a pushing or pulling force, thereby driving the piston rod to extend or retract, realizing the reciprocating motion of the hydraulic cylinder 32.

[0035] Please see Figure 4-5 In some embodiments, the repair head 4 is a tamping plate 42 for compacting ground fill or a compaction block 41 for crushing ground gravel. When crushing gravel is required, the compaction block 41 is installed on the power end of the hydraulic cylinder 32 to perform the crushing operation; when asphalt filler compaction is required, the tamping plate 42 is installed on the power end of the hydraulic cylinder 32 to perform the filler compaction operation. Selecting the appropriate repair head 4 according to the actual operation helps to further ensure repair quality and improve repair efficiency.

[0036] In some embodiments, the frame 1 further includes pulleys 12, which are mounted on the bottom of the frame 1. The pulleys 12 allow the road repair device to move more easily on the road surface, whether en route to the repair location or during the repair process when the device's position needs to be adjusted. This facilitates movement, reduces the workload of operators, and improves work efficiency. Furthermore, since road surfaces may have some unevenness or slope, the pulleys 12 can adapt well to these changes, allowing the device to move stably on different road conditions without being significantly affected by minor undulations or inclinations, thus ensuring the stability and safety of the device during movement.

[0037] In some embodiments, the frame 1 further includes a push rod 13, which is fixedly mounted on the rear side of the frame 1. The user moves the device by pushing the push rod 13, which effectively transmits the force applied by the user to the device, converting it into forward or backward propulsion. Compared to directly pushing the device, the push rod 13 provides a more convenient and less strenuous method of applying force, allowing the operator to better control the movement of the device. Simultaneously, by changing the pushing direction of the push rod 13, the direction of travel of the device can be guided. When approaching the repair location, the operator can fine-tune the direction of the push rod 13 to ensure the device accurately reaches the designated position.

[0038] Please see Figure 3In some embodiments, the outer peripheral wall of the support platform 2 has multiple observation ports 22 communicating with the operating space 21. On one hand, the observation ports 22 can be used to check the operation of the repair head 4, hydraulic cylinder 32, etc. Through observation, abnormal wear, loosening, and other problems of components can be detected in a timely manner, allowing for maintenance and upkeep before a failure occurs, preventing serious equipment malfunctions, and improving the reliability and service life of the equipment. On the other hand, during device operation, the observation ports 22 allow the user to confirm that no foreign objects have entered the device or other safety hazards have arisen. Simultaneously, it allows operators to understand the internal situation without opening the device, avoiding safety accidents caused by direct contact with operating components.

[0039] Please see Figure 3 In some embodiments, a rib plate 23 is also included. The rib plate 23 is located on the outer periphery of the support platform 2, and the rib plate 23 is fixedly connected to the support platform 2 and the frame 1 respectively. The rib plate 23 is provided to further fix the support platform 2, ensuring that the support platform 2 remains stable during use and will not loosen or even fall off as the repair head 4 moves.

[0040] Please see Figure 3 In some embodiments, the power assembly 3 further includes a connector 34, which is fixedly connected to the power end of the hydraulic cylinder 32. The repair head 4 is detachably connected to the power end of the hydraulic cylinder 32 via the connector 34. The connector 34 enhances the stability of the connection between the repair head 4 and the power end of the hydraulic cylinder 32, facilitating the disassembly, replacement, and maintenance of the repair head 4.

[0041] In some embodiments, the support platform 2 is connected to the frame 1, the hydraulic station 31 is connected to the frame 1, and the hydraulic cylinder 32 is connected to the support platform 2 by bolts. The bolted connections facilitate the disassembly and installation of the components, providing convenience for future equipment maintenance and repair.

[0042] In summary, the road repair device provided in this embodiment is suitable for repairing road potholes, effectively ensuring the effect of crushed stone and the compaction of asphalt filler, guaranteeing the repair effect and smoothness of potholes, and has a simple overall structure, which helps to save manpower.
