Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a rapid repair material paving device for rutting-resistant asphalt pavement. Background Technology

[0002] Asphalt materials have good wear resistance and durability. Laying asphalt on the road surface can improve the service life of the road surface. At the same time, asphalt pavement has good smoothness, which can improve the comfort and safety of vehicles during driving. Asphalt pavement can also prevent rainwater from penetrating into the lower layer of the road surface, reducing road damage. Rutting-resistant asphalt pavement repair is a maintenance operation that restores the smoothness, load-bearing capacity and deformation resistance of asphalt pavement caused by long-term vehicle traffic (especially repeated rolling by heavy vehicles and softening of asphalt under high temperature environment). It is characterized by rutting at wheel tracks, road surface displacement and deformation, and reduced smoothness. It uses special rutting-resistant repair materials and suitable processes to restore the smoothness, load-bearing capacity and deformation resistance of the road surface.

[0003] Patent document CN220503634U discloses a repair and paving device for asphalt roads. It includes a mobile vehicle body with a sealing groove inside. A first sealing plate and a second sealing plate are slidably connected inside the sealing groove. Two sets of second racks are fixedly connected to the lower surface of the first sealing plate, and two sets of first racks are fixedly connected to the lower surface of the second sealing plate. A transmission gear meshes between the first and second racks on the same side. A storage tank is fixedly connected to the upper surface of the mobile vehicle body. A cylinder is fixedly installed on the left side of the mobile vehicle body. The piston rod in the cylinder is fixedly connected to the side of the second sealing plate. The piston rod pushes the second sealing plate inward, and simultaneously, through the interaction of the first and second racks, drives the first sealing plate to slide inward. The first and second sealing plates seal the discharge port, preventing internal asphalt from flowing out, reducing resource waste, improving resource utilization efficiency, and maintaining the integrity of the road surface.

[0004] The repair paving device does not mention the presence of a paving structure. In asphalt road repair, before the asphalt repair material in the pothole is initially compacted and leveled, it is necessary to evenly spread the asphalt repair material into the pothole. Without a paving structure, uneven paving thickness, material accumulation or missing parts may occur, which in turn will cause problems with subsequent compaction and road performance.

[0018] Please see Figures 1-5 A rapid repair material paving device for rutting-resistant asphalt pavement includes a device body 1, multiple sets of rollers 2 on the device body 1, and a paving device for uniformly spreading the repair material. The paving device includes a limiting mechanism for limiting the repair material to the repair area and a dispersing mechanism for uniformly dispersing the material accumulated at the repair area during the movement of the device body 1. The limiting mechanism includes two sets of mutually cooperating limiting plates 3, and the dispersing mechanism includes a paving plate 4 that can cooperate with the limiting plates 3 and reciprocate. The side of the paving plate 4 that contacts the repair material is provided with toothed protrusions 24. The main body 1 of the device serves as the core load-bearing and installation foundation for the entire paving device. All functional components (such as the roller 2, paving device, motor 10, and telescopic lifting column 12) are directly or indirectly assembled on it, providing a stable installation platform and structural support for each component. It also drives the entire device to move on the road surface to be repaired, forming the basic framework for the device to perform repair operations. The roller 2 is used to compact the evenly spread anti-rutting asphalt repair material after the repair material is laid. Through rolling and squeezing, the repair material is made to adhere tightly to the road surface to be repaired, enhancing the density and structural stability of the repair material, reducing the risk of subsequent road surface settlement and cracking, and ensuring the load-bearing capacity and service life of the repaired road surface. There are two sets of limiting plates 3, which are... The paving plate 4, located on one side of the main body 1 in the forward direction, works in conjunction with the device to confine the anti-rutting asphalt repair material within the area to be repaired during the movement of the device and the dispersion of materials by the paving plate 4. This prevents the repair material from spreading outwards before paving and ensures that the repair material is precisely concentrated on the road surface that needs repair. The paving plate 4 is located at the rear end of the limiting plate 3 and can work with the limiting plate 3 to move back and forth. Its core function is to evenly disperse and spread the repair material accumulated in the pothole during the movement of the main body 1. The toothed protrusions 24 can enhance the contact friction between the paving plate 4 and the repair material, so that the paving plate 4 can better drive the repair material to disperse during the reciprocating movement, further improving the paving uniformity.

[0019] Please see Figure 3 The limiting plate 3 is located on the side of the device body 1 that moves forward. The device body 1 is equipped with a mounting frame 5 that is movable to the upper limit. A bidirectional lead screw 6 is rotatably mounted on the mounting frame 5. Two sets of lead screw nuts 7 are meshed on the bidirectional lead screw 6. A connecting frame 8 is mounted on the lead screw nuts 7, and one end of the connecting frame 8 is fixedly connected to the outside of the limiting plate 3. A gear 9 is mounted on the bidirectional lead screw 6. A motor 10 is mounted on the mounting frame 5. A gear 11 that meshes with the gear 9 is mounted on the output end of the motor 10. A telescopic lifting column 12 is mounted on the device body 1, and the output end of the telescopic lifting column 12 is fixedly connected to the outside of the mounting frame 5. Mounting bracket 5 serves as the mounting carrier for the limiting mechanism (limiting plate 3, double-acting screw 6, etc.). When the double-acting screw 6 rotates under the drive of motor 10, it can drive two sets of screw nuts 7 to move synchronously towards or away from each other along the axial direction of the double-acting screw 6 through the oppositely helical threads. This, in turn, drives the two sets of limiting plates 3 to move synchronously closer or further away through connecting bracket 8, thereby adjusting the distance between the two sets of limiting plates 3 to accommodate road surface areas of different widths to be repaired. Motor 10 drives gear 11 to rotate through its output end, and then drives the double-acting screw 6 to rotate through the meshing transmission between gear 11 and gear 9. Ultimately, the spacing between the two sets of limiting plates 3 is adjusted to ensure that the limiting plates 3 can be flexibly adjusted according to the width of the road surface to be repaired, meeting different operational needs. The telescopic lifting column 12 drives the mounting frame 5 and the limiting mechanism (limiting plate 3, double screw 6, etc.) installed on the mounting frame 5 to rise and fall as a whole through its own telescopic movement. On the one hand, the height of the limiting plate 3 can be adjusted according to the depth of the depression of the road surface to be repaired or the thickness of the repair material to ensure the limiting effect. On the other hand, when the device is moved or in a non-operational state, the limiting plate 3 can be lifted off the ground to prevent the limiting plate 3 from being damaged by friction with the ground.

[0020] Please see Figure 4 and Figure 5 The main body 1 of the device is provided with a sliding rod 13, and a sleeve 14 is slidably provided on the sliding rod 13. A connecting part 15 is provided at the bottom end of the sleeve 14, and one end of the connecting part 15 is fixedly connected to the outside of the paving plate 4. The paving plate 4 is located at the rear end of the limiting plate 3. A frame 16 is provided on the main body 1 of the device. A movable frame 17 is provided on the front of the frame 16. A connecting part 28 is provided at both ends of the movable frame 17, and one end of the connecting part 28 is fixedly connected to the top end of the sleeve 14. A connecting groove 22 is provided in the middle part of the movable frame 17. A turntable 19 is rotatably provided on the frame 16. A connecting block 20 that cooperates with the connecting groove 22 is provided on one side of the turntable 19. A rotating wheel 21 is rotatably provided on the connecting block 20. A motor 23 is provided on the back of the frame 16, and the output end of the motor 23 is fixedly connected to the outside of the turntable 19. The sliding rod 13 restricts the sliding trajectory of the sleeve 14, ensuring that the sleeve 14 can only slide smoothly along the axial direction of the sliding rod 13. This ensures that the paving plate 4 connected to the sleeve 14 will not shift laterally during reciprocating movement, guaranteeing a uniform spreading effect of the repair material. The sleeve 14 serves as the connecting carrier between the sliding rod 13, the paving plate 4, and the movable frame 17. On one hand, when sliding along the sliding rod 13, it drives the paving plate 4 to reciprocate synchronously, providing stable sliding support for the paving plate 4. On the other hand, it transmits the reciprocating motion of the movable frame 17 to the paving plate 4, giving the paving plate 4 the power for reciprocating paving. The frame 16 provides a limited movement space for the movable frame 17, a rotation mounting point for the turntable 19, and a stable mounting platform for the motor 23, ensuring that all components of the dispersing mechanism can work together, providing power and structural support for the reciprocating movement of the paving plate 4. The movable frame 17 is located on the turntable. Driven by the connecting block 20, the turntable 19 moves in a reciprocating linear motion along the front of the frame 16. Through the connecting component 2 18, it drives the sleeve 14 to slide along the slide bar 13, thereby indirectly driving the paving slab 4 to perform reciprocating paving operations. It is a key transmission component that converts the rotational motion of the turntable 19 into the linear reciprocating motion of the paving slab 4. The turntable 19 rotates under the drive of the motor 23. Through the cooperation of the connecting block 20 and the connecting groove 22 on the movable frame 17, it converts its own rotational motion into the reciprocating linear motion of the movable frame 17, providing a power basis for the reciprocating paving of the paving slab 4. When the connecting block 20 rotates with the turntable 19, the wheel 21 rolls along the inner wall of the connecting groove 22, converting the sliding friction between the connecting block 20 and the connecting groove 22 into rolling friction, which greatly reduces the friction loss between the two, extends the service life of the components, and ensures the stability and smoothness of the reciprocating motion of the movable frame 17.

[0021] Working principle: Based on the width of the pit to be repaired, start motor 10 on mounting bracket 5. The output end of 10 drives gear 11 to rotate. Through the meshing transmission between gear 11 and gear 9 on the double-acting screw 6, the double-acting screw 6 is driven to rotate on the mounting frame 5. Because the double-acting screw 6 has two sections of threads with opposite directions of rotation, its rotation will drive two sets of meshing screw nuts 7 to move synchronously in opposite directions along the axial direction. The screw nuts 7 then drive two sets of limiting plates 3 to move synchronously closer / away from each other through the connecting frame 8, until the distance between the two sets of limiting plates 3 is completely matched with the width of the pit. According to the pit depth and the planned thickness of the repair material, the telescopic lifting column 12 on the main body 1 of the control device extends and retracts. The output end of the telescopic lifting column 12 is fixedly connected to the mounting frame 5. Its extension and retraction will drive the mounting frame 5 and the upper limit mechanism of the frame to rise and fall as a whole, until the bottom of the limiting plate 3 is matched with the height of the ground at the edge of the pit. The main body 1 moves the entire device along the road surface to be repaired. Two sets of limiting plates 3 located on the advancing side of the main body 1 enter the working area first, confining the anti-rutting asphalt repair material into the pothole between the two sets of limiting plates 3, completely preventing the material from spreading out of the pothole, ensuring that all repair material is concentrated in the pothole, solving the "material shortage" problem from the source, and laying the foundation for "material localization" for subsequent uniform distribution. While the main body 1 moves, the second motor 23 on the back of the frame 16 is started. The output end of the second motor 23 drives the turntable 19 to rotate on the frame 16. The connecting block 20 on one side of the turntable 19 rotates synchronously with the turntable 19. The rotating wheel 21 on the connecting block 20 is embedded in the connecting groove 22 in the middle of the movable frame 17. Through the rolling of the rotating wheel 21 in the connecting groove 22, the movable frame 17 is pushed to make reciprocating linear motion along the front of the frame 16. The movable frame 17 is fixedly connected at both ends to the sleeve 14 on the slide rod 13 via connecting component 2 18. Its reciprocating motion drives the sleeve 14 to slide smoothly along the axis of the slide rod 13. The sleeve 14 then drives the paving plate 4 to move back and forth synchronously via connecting component 15 at the bottom. Since the paving plate 4 is located at the rear end of the limiting plate 3, and the side in contact with the material is provided with toothed protrusions 24, the toothed protrusions 24 can enhance the friction between the paving plate 4 and the repair material, preventing the material from slipping. Its reciprocating movement can completely disperse and flatten the repair material accumulated in the pit, accurately control the paving thickness at each point, and fundamentally solve the problems of "uneven thickness and material accumulation". After the repair material is evenly spread by the paving slab 4, multiple sets of rollers 2 on the main body 1 of the device move with the device to roll and compact the spread repair material. Through the squeezing action of the rollers 2, the repair material is made to fit tightly into the pothole base layer, eliminating the voids inside the material, further enhancing the advantages brought by the uniformity of paving, avoiding problems such as local settlement and cracking after compaction due to uneven paving in the early stage, and ultimately ensuring the load-bearing capacity and service life of the repaired road surface.
