Description

Technical Field

[0001] This utility model relates to the field of road surface repair technology, specifically to a layered paving and leveling device for treating uneven settlement of road surface. Background Technology

[0002] Over long-term use, roads often experience uneven surface settlement due to repeated vehicle loads, base layer subsidence, or environmental changes. This settlement creates potholes and undulations, affecting vehicle stability and posing safety hazards. Current repair methods typically involve directly filling the settlement area with repair material and then leveling it with a scraper. However, in practice, the scraper angle and height cannot be flexibly adjusted to adapt to road surface irregularities, often requiring manual experience to control the thickness. This results in uneven repair layers, even localized material buildup or hollow areas, leading to poor surface smoothness and durability after repair.

[0003] Therefore, it is necessary to propose a layered paving and leveling device for treating uneven settlement of road surface layers to solve the above-mentioned technical defects. Utility Model Content

[0004] The purpose of this invention is to provide a layered paving and leveling device for treating uneven settlement of road surface layers, so as to solve the problem mentioned in the background art that leveling can only be done by manual operation experience and the repair layer is prone to uneven thickness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered paving and leveling device for treating uneven settlement of road surface, comprising a back plate and a first rotating seat. Angle frames are fixed to both sides of the back plate. The first rotating seat is fixedly connected to the front wall of the back plate. A first swing arm is rotatably sleeved on the outside of the first rotating seat. A second rotating seat is also fixed to the front wall of the back plate. A second swing arm is rotatably sleeved on the outside of the second rotating seat. The bottom end of the first swing arm is rotatably connected to a connector. The bottom end of the second swing arm is welded to a bushing. A threaded block is fixedly connected to the bottom end of the connector. A threaded rod is screwed into the threaded block. A hollow shaft is rotatably connected to the right side of the threaded rod. The bushing is sleeved on the outside of the hollow shaft. A screw motor is installed on the right side of the hollow shaft. The output shaft of the screw motor passes through the hollow shaft and is fixedly connected to the threaded rod. A scraper frame is assembled at the bottom end of the threaded rod. A paving scraper is installed at the bottom end of the scraper frame.

[0006] As a further technical solution of this utility model, the second swing arm and the bushing form a relatively vertical inverted "T" structure, the right side of the scraper frame is fixedly connected to the outer wall of the screw motor, and the left side of the scraper frame is movably connected to the threaded rod.

[0007] As a further technical solution of this utility model, a movable groove is provided at the bottom end of the back plate along its length direction, a toothed rail is fixedly connected to the top inner end of the back plate, and a movable seat is slidably sleeved on the outside of the toothed rail.

[0008] As a further technical solution of this utility model, two sets of gears are installed inside the movable seat, and a movable motor is fixed on one side of the outer wall of the movable seat. The movable motor is connected to a set of gears via a chain.

[0009] As a further technical solution of this utility model, a slider is welded to the top of the movable seat, the slider is embedded in the top of the toothed rail and slides, a laser rangefinder is fixedly connected to one end of the bottom of the movable seat, a fixing component is fixedly installed on the outside of the laser rangefinder, and the fixing component is embedded in the movable groove and moves.

[0010] As a further technical solution of this utility model, a wedge-shaped groove is provided at the bottom of the scraper frame, the shape of which matches the top of the paving scraper, and screws are used to fix the scraper frame and the paving scraper together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a moving motor, screw, threaded block, first swing arm, scraper frame and paving scraper, the paving scraper can automatically adjust the angle and height according to the settlement, ensuring that the bottom is always parallel to the road surface, thereby achieving precise leveling of the settlement area. The device can achieve leveling while moving under the drive of the repair vehicle, which solves the problems of uneven thickness of manual repair and the inability of the scraper to adjust with the settlement surface, so that the repaired road surface layer is flat and dense, improving the road's load-bearing capacity and driving comfort.

[0012] Equipped with a moving motor, chain, gears, toothed rails, moving seat, slider, laser rangefinder, and moving groove, the laser rangefinder moves synchronously and performs laser ranging on the road surface in real time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides an embodiment of a layered paving and leveling device for treating uneven settlement of road surface layers, comprising a back plate 1 and a first rotating seat 5. Angle brackets 2 are fixed to both sides of the back plate 1. The first rotating seat 5 is fixedly connected to the front wall of the back plate 1. A first swing arm 6 is rotatably sleeved on the outside of the first rotating seat 5. A second rotating seat 16 is also fixed to the front wall of the back plate 1. A second swing arm 15 is rotatably sleeved on the outside of the second rotating seat 16. The bottom end of the first swing arm 6 is rotatably connected to a connector 7. The bottom end of the second swing arm 15 is welded to a bushing 13. A threaded block 8 is fixedly connected to the bottom end of the connector 7. A threaded rod 9 is screwed into the inner part of the texture block 8. A hollow shaft 12 is rotatably connected to the right side of the threaded rod 9. A bushing 13 is sleeved on the outside of the hollow shaft 12. A screw motor 14 is installed on the right side of the hollow shaft 12. The output shaft of the screw motor 14 passes through the hollow shaft 12 and is fixedly connected to the threaded rod 9. A scraper frame 10 is assembled at the bottom end of the threaded rod 9. A paving scraper 11 is installed at the bottom end of the scraper frame 10. The second swing arm 15 and the bushing 13 form a relatively vertical inverted "T" structure. The right side of the scraper frame 10 is fixedly connected to the outer wall of the screw motor 14, and the left side of the scraper frame 10 is movably connected to the threaded rod 9. Specifically, such as Figure 1 and Figure 4As shown, the screw motor 14 is model MHMD042G1U. After the screw motor 14 starts, its output shaft drives the hollow shaft 12 to rotate at high speed. The hollow shaft 12 is fixedly connected to the threaded rod 9, so that the threaded rod 9 rotates synchronously. The thread of the threaded rod 9 is a standard trapezoidal thread, and its thread helix angle is less than the equivalent friction angle. This thread structure naturally has self-locking characteristics. During the rotation of the threaded rod 9, the threaded block 8 undergoes linear reciprocating motion under the helical drive of the threaded rod 9. When the threaded block 8 moves to the left, it will pull the first swing arm 6 to swing clockwise, thereby lifting the scraper frame 10 as a whole to the upper left, so that the bottom of the paving scraper 11 is raised. Conversely, when the threaded block 8 moves to the right, it will drive the first swing arm 6 to swing clockwise. 6. The counterclockwise swing causes the scraper frame 10 to be pulled upward and to the right, which in turn causes the bottom of the paving scraper 11 to press down accordingly. Throughout the process, the inverted "T" structure formed by the second swing arm 15 and the bushing 13 provides stable balance support, preventing the scraper frame 10 from swaying left and right during operation. Through this combination of drive and support, the angle and height of the paving scraper 11 can be adjusted in real time according to the different undulations of the settled road surface, ensuring that its bottom is always parallel to the road surface, thereby achieving precise leveling. This solves the problem that traditional repair scrapers cannot be flexibly adjusted with the settlement surface, making the paving layer more uniform and dense, reducing local material accumulation or hollow areas, and improving the smoothness and load-bearing capacity of the repaired road surface.

[0017] A movable groove 17 is provided at the bottom end of the back plate 1 along its length direction. A toothed rail 19 is fixedly connected to the top end of the back plate 1. A movable seat 20 is slidably sleeved on the outside of the toothed rail 19. Two sets of gears 21 are installed inside the movable seat 20. A movable motor 22 is fixed on one side of the outer wall of the movable seat 20. The movable motor 22 is connected to a set of gears 21 by a chain. A slider 18 is welded to the top of the movable seat 20. The slider 18 is embedded in the top of the toothed rail 19 and slides. A laser rangefinder 3 is fixedly connected to one end of the bottom of the movable seat 20. A fixing part 4 is fixedly installed on the outside of the laser rangefinder 3. The fixing part 4 is embedded in the movable groove 17 and moves. Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the mobile motor 22 is model 60ST-M01930. When the mobile motor 22 starts, it drives the chain belt to rotate, which in turn drives the gear 21 to rotate. After the gear 21 meshes with the toothed rail 19, it pushes the moving seat 20 to move smoothly along the length direction on the toothed rail 19. The moving seat 20 drives the slider 18 above it to slide on the top of the toothed rail 19, providing a limiting and guiding function to maintain overall stability in the walking direction. Simultaneously, the laser rangefinder 3, fixed at one end of the bottom of the moving seat 20, moves synchronously with the moving seat 20. The laser rangefinder 3 is model Leica DISTO. D510, the laser rangefinder 3 continuously emits a laser beam to measure the distance of road surface settlement areas in real time, and feeds back the detected undulation data to the screw motor 14. The screw motor 14 further controls the rotation of the threaded rod 9 and the left and right movement of the threaded block 8, so that the first swing arm 6 and the scraper frame 10 automatically adjust their angles, allowing the paving scraper 11 to flexibly rise and fall with the undulations of the road surface, ultimately ensuring that the paving layer thickness remains consistent. This solves the problem of uneven thickness and wavy defects caused by traditional manual operation based on experience, and makes the repaired road surface smoother and straighter.

[0018] The scraper frame 10 has a wedge-shaped groove 23 at its inner bottom end. The shape of the wedge-shaped groove 23 matches the top of the paving scraper 11. The scraper frame 10 and the paving scraper 11 are fixedly connected by screws 24. Specifically, such as Figure 1 and Figure 4 As shown, the paving scraper 11 is stably embedded by the wedge-shaped groove 23 at the bottom of the scraper frame 10. Then, the worker uses screws 24 to firmly lock the paving scraper 11 under the scraper frame 10. During the paving operation, even under the combined action of high-frequency vibration and scraping pressure, it can be ensured that the paving scraper 11 and the scraper frame 10 will not fall off or loosen. When the paving scraper 11 loses its flatness due to long-term wear or local bending, the operator only needs to loosen the screws 24 to quickly disassemble and replace it without having to disassemble the entire scraper frame 10. This saves maintenance time and reduces maintenance costs.

[0019] Working principle: When in use, the device is first connected to the repair vehicle body via the back plate 1. As the repair vehicle slowly moves forward in the road subsidence area, the entire layered paving and leveling device is pulled forward. The moving seat 20 moves along the length direction on the toothed rail 19. The moving motor 22 drives the chain belt, and the chain belt drives the gear 21 to mesh with the toothed rail 19, ensuring smooth movement of the moving seat 20. The laser rangefinder 3 moves synchronously and emits a laser beam to the road surface in real time, acquiring road surface undulation data and feeding it back to the screw motor 14. After receiving the ranging signal from the laser rangefinder 3, the screw motor 14 starts. The output shaft drives the hollow shaft 12 and the threaded rod 9 to rotate. The threaded block 8 moves linearly on the outer surface of the threaded rod 9, causing the first swing arm 6 to deflect at an angle, thereby driving the scraper frame 10 and the paving scraper 11 to be lifted up and down as a whole. When the threaded block 8 moves to the left, the first swing arm 6 swings clockwise, causing the paving scraper 11 to rise. When the threaded block 8 moves to the right, the first swing arm 6 swings counterclockwise, causing the paving scraper 11 to press down. The inverted "T" structure formed by the second swing arm 15 and the bushing 13 provides balanced support for the scraper frame 10, so that the scraper remains stable and does not shake during the movement. During continuous paving, the bottom end of the paving scraper 11 remains stable through its engagement with the wedge groove 23 and the fixing of the screw 24. When wear occurs, the scraper can be quickly replaced to ensure construction continuity. The angle and height of the paving scraper 11 can be continuously corrected according to the real-time measurement results of the laser rangefinder 3, so that the bottom end of the scraper is always parallel to the road settlement surface. This enables layered paving, and the repair material is evenly spread and fills the settlement area.
