Description

Technical Field

[0001] The invention relates to the technical field of road maintenance, in particular to a paving and leveling device for small potholes on an asphalt pavement. Background Art

[0002] During road maintenance operations, large-scale paving machinery cannot be used for local small-area milling and re-paving. Manual pouring and leveling make it difficult to control the loose paving coefficient and flatness, resulting in poor flatness or insufficient compaction of the road surface after maintenance, posing quality risks.

[0003] Currently, there is a lack of a device that can be used to pre-scrape the surface of the pit after the mixture is introduced into the pit, so as to scrape off the excess mixture and achieve a preset loose paving thickness.

[0004] Therefore, in view of the above problems, an asphalt pavement small pothole paving and leveling device is proposed to solve the above problems. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention develops a paving and leveling device for small potholes in asphalt pavement, which can introduce mixture into the potholes and level the pavement.

[0006] The technical solution to the technical problem solved by the present invention is as follows: the present invention provides a paving and leveling device for small potholes on an asphalt pavement, comprising a paving and leveling assembly and a power assembly; the paving and leveling assembly comprises a leveling block, the front end of the leveling block is connected to the leveling plate, the leveling block is provided with an arc groove and a notch, the arc groove is connected to the notch, a leveling column is provided in the arc groove, and the central axis bearing of the leveling column is connected to the leveling block; the leveling block is rotatably connected to the lower end of the symmetrical connecting rod, and the upper ends of the symmetrical connecting rods are respectively rotatably connected to the long round rods, the symmetrical long round rods are respectively connected to the vertical rods, the symmetrical vertical rods are respectively rotatably connected to the connecting shafts, the symmetrical connecting shafts are respectively connected to the T-shaped rods, and the symmetrical T-shaped rods are respectively connected to the symmetrical drop tubes; the power assembly comprises a movable frame, the movable frame is connected to the symmetrical lower guide rods, the symmetrical lower guide rods respectively pass through the leveling blocks, the movable frame is connected to the symmetrical L guide plates, and the symmetrical vertical rods respectively pass through the corresponding L guide plates. The front end of the leveling plate of this device is sharp, which is convenient for leveling after paving, and the leveling column can then be rolled to level it.

[0007] As an optimization, the vehicle frame assembly is further included, comprising a vehicle frame connected to symmetrical mounting risers, each of which is connected to symmetrical upper guide rods, each of which is connected to a power screw by a bearing, one of which is connected to a power motor, the output shaft of the power motor is connected to the power screw, the power screw is threadedly connected to a guide cylinder, the symmetrical upper guide rods pass through corresponding guide cylinders, the three guide cylinders are respectively connected to a connecting frame, and the connecting frame is connected to the moving frame. By using a power motor and a threaded connection, the paving and leveling assembly can be moved along the pit, thereby achieving pit treatment.

[0008] As an optimization, the symmetrical vertical rods are connected to hydraulic rods, and the piston rods of the symmetrical hydraulic rods are connected to triangular blades. Pressure sensors are installed within the triangular blades. By using triangular blades, a groove that is wider at the top and narrower at the bottom is created at the bottom of the pit, increasing the contact area between the mixture and the original road surface and ensuring full contact between the mixture and the original road surface.

[0009] As an optimization, the symmetrical triangular blades are respectively provided with symmetrical triangular grooves and symmetrical track grooves. Each triangular groove is connected to the corresponding track groove. Each triangular groove is respectively provided with an inverted triangular blade, each of which is respectively connected to the vertical groove. Each of the vertical grooves is respectively provided with a round block, and each of the round blocks is respectively connected to the corresponding T-shaped rod. By adopting the inverted triangular blade, the inverted triangular blade can move back and forth along the triangular groove, making it easier for the inverted triangular blade to open a triangular groove that is narrow at the top and wide at the bottom. The mixture is poured into the triangular groove, so that the mixture is staggered and connected with the original road surface, and the repair effect is better.

[0010] As an optimization, each of the inverted triangular blades is connected to a tapered pin, which is first chiseled to form a groove to facilitate the movement of the inverted triangular blade, and a triangular groove that is narrow at the top and wide at the bottom is opened in the groove.

[0011] As an optimization, the symmetrical L-shaped guide plates each pass through a circular groove, each bearing connected to the central axis of the second gear, the symmetrical vertical rods each connect to the second rack via a rack mounting bracket, the symmetrical second racks each mesh with the corresponding second gears, and the symmetrical second gears each connect to a power round block, and the symmetrical T-shaped rods each have a straight groove, and the symmetrical power round blocks each are placed in the corresponding straight groove. By using gear and rack meshing, the power round blocks are placed in the straight groove, providing power for the movement of the triangular blade.

The symmetrical circular grooves are connected to limiting rods, and each limiting rod is placed in the corresponding arc top groove. By using the arc top groove, the position of the circular groove can be adjusted. When the limiting rods are at the ends of the arc top groove, the paving and leveling components are at the ends of the pit, so that the power round block is located at the lower side of the straight groove. When the power round block moves, the drop tube swings to the maximum angle, matching the larger angle of the pit edge, so that the mixture is better fitted to the original road surface.

[0014] As an optimization, the frame is connected to at least one first rack, the first rack meshes with a first gear, and the first gear is connected to the central axis of the leveling column. The use of the rack and gear meshing provides power support for the rotation of the leveling column.

[0015] As an optimization, a leveling power assembly is also included. The leveling power assembly includes a leveling motor. The leveling motor is connected to the mobile frame via a motor bracket. The output shaft of the leveling motor is connected to one end of a crank. The other end of the crank is rotatably connected to one end of a rocker. The other end of the rocker is rotatably connected to the leveling block. By using the leveling motor and the crank-rocker mechanism, power is provided for the reciprocating motion of the leveling plate and the leveling column.

[0016] The effects provided in the summary of the invention are only the effects of the embodiments, rather than all the effects of the invention. The above technical solution has the following advantages or beneficial effects: 1. This device uses triangular and inverted triangular blades to create grooves within the pit, increasing the contact area between the mixture and the original pavement and ensuring full contact between the mixture and the original pavement. The inverted triangular blade creates a triangular groove that is narrow at the top and wide at the bottom. The mixture is poured into the triangular groove, creating an interlaced connection between the mixture and the original pavement, achieving a better repair effect. The pit is first chiseled using a tapered pin to facilitate the movement of the inverted triangular blade, creating a triangular groove that is narrow at the top and wide at the bottom.

[0017] 2. The power block of this device swings back and forth along the straight groove, driving the T-bar and drop tube to swing back and forth. The drop tube swings and sprays the mixture into the pit. The screed plate scrapes the mixture flat, and the leveling column rotates and rolls the scraped mixture, achieving pit paving and leveling. Furthermore, by using an arc-top groove, when the limiting round rod is at the two ends of the arc-top groove, the paving and leveling components are at the two ends of the pit, placing the power block at the lower side of the straight groove. When the power block moves, the drop tube swings at its maximum angle, matching the larger angle of the pit edge, ensuring a better fit between the mixture and the existing road surface.

The U-shaped frame 43 matches the guide groove 13. The adjusting screw 42 is connected to the adjusting handle 41. By adopting the wheel assembly 4, the transfer of the device is facilitated. When the device is moved above the pit, the wheel 44 is moved into the empty groove 14 by rotating the adjusting handle 41, so that the frame 11 contacts the road surface, which facilitates paving and leveling.

[0037] Embodiment 1: The symmetrical L-shaped guide plates 38 are connected to the corresponding circular grooves 215 .

[0038] The workflow of this embodiment is: The device is pushed to move. When the vehicle frame 11 moves to the center of the pit, the device is stopped and the adjustment handle 41 is turned to make the vehicle frame 11 contact the ground.

[0039] Use a hose to connect one end to the mixture source and the other end to the drop tube 221. Control the rotation of the power motor 33 and the leveling motor 51. The power motor 33 drives the power screw 32 to rotate. The power screw 32 drives the guide cylinder 34, the connecting frame 35, the movable frame 36, the lower guide rod 37, the L guide plate 38, the leveling power assembly 5 (except the first rack 54), and the paving leveling assembly 2 to move. The guide cylinders 34 on both sides move along the upper guide rod 31. The leveling motor 51 drives the crank 52 to rotate. The crank 52 causes the rocker 53 to swing.

[0040] Embodiment 2: The vehicle frame 11 is connected to symmetrical limiting vertical plates 15, each of which is provided with an arc top groove 16. The symmetrical circular grooves 215 are respectively connected to limiting rods 226, and each limiting rod 226 is respectively disposed within the corresponding arc top groove 16. By adopting the arc top groove 16, the position of the circular groove 215 can be adjusted. When the limiting rods 226 are at the two ends of the arc top groove 16, the paving and leveling assembly 2 is at the two ends of the pit, so that the power block 213 is located at the lower side of the straight groove 219. When the power block 213 moves, the drop tube 221 swings to the maximum angle, matching the larger angle of the pit edge, so that the mixture is better fitted to the original road surface.

[0041] The workflow of this embodiment is: When the power motor 33 rotates, the circular groove 215 drives the limiting rod 226 to move along the arc top groove 16, the limiting rod 226 drives the circular groove 215 to move along the L guide plate 38, and the circular groove 215 drives the second gear 214 and the power round block 213 to move.

[0042] Example 3: This example further elaborates on Example 1 or 2. The symmetrical vertical rods 28 are connected to hydraulic rods 210, and the piston rods of the symmetrical hydraulic rods 210 are connected to triangular blades 211. Pressure sensors are installed within the triangular blades 211. By using the triangular blades 211, a groove with a wide top and narrow bottom is created at the bottom of the pothole, increasing the contact area between the mixture and the original road surface, ensuring full contact between the mixture and the original road surface.

[0043] The workflow of this embodiment is: When the vertical rod 28 moves downward, the hydraulic rod 210 is controlled to move downward, so that the triangular blade 211 cuts the bottom of the groove downward into a V shape, thereby increasing the contact area between the mixture and the original road surface.

[0044] Example 4: This example further elaborates on Example 3. The symmetrical triangular blades 211 are respectively provided with symmetrical triangular grooves 216 and symmetrical track grooves 217. Each triangular groove 216 is connected to the corresponding track groove 217. Each triangular groove 216 is respectively provided with an inverted triangular blade 224. Each inverted triangular blade 224 is respectively connected to the vertical groove 225. Each vertical groove 225 is respectively provided with a round block 222. Each round block 222 is respectively connected to the corresponding T-shaped rod 218. By adopting the inverted triangular blade 224, the inverted triangular blade 224 can move back and forth along the triangular groove 216, making it easier for the inverted triangular blade 224 to open a triangular groove that is narrow at the top and wide at the bottom. The mixture is poured into the triangular groove, so that the mixture is staggered and connected with the original road surface, and the repair effect is better.

[0045] Each of the inverted triangular blades 224 is connected to a tapered pin 223. The tapered pin 223 first chisels a groove to facilitate the movement of the inverted triangular blade 224, and a triangular groove with a narrow top and a wide bottom is opened in the groove.

[0046] The workflow of this embodiment is: T-shaped rod 218 drives round block 222 to swing within vertical slot 225. Round block 222 drives vertical slot 225 to reciprocate along track slot 217. Vertical slot 225 drives inverted triangular blade 224 to reciprocate along triangular slot 216. Inverted triangular blade 224 drives conical pin 223 to reciprocate. Conical pin 223 first digs the pit, then inverted triangular blade 224 creates a triangular groove that is narrow at the top and wide at the bottom. Mixed material is poured into the triangular groove, interlacing the mixed material with the original road surface, achieving a better repair effect.

[0047] This device, by providing a triangular blade 211 and an inverted triangular blade 224, creates a groove within the pit, increasing the contact area between the mixture and the original pavement and ensuring full contact between the mixture and the original pavement. The inverted triangular blade 224 creates a triangular groove that is narrow at the top and wide at the bottom. The mixture is poured into the triangular groove, creating an interlaced connection between the mixture and the original pavement, resulting in a more effective repair. The conical pin 223 is provided to initially chisel the pit, facilitating the movement of the inverted triangular blade 224, creating a triangular groove that is narrow at the top and wide at the bottom within the pit.

[0048] The power block 213 of this device reciprocates along the straight groove 219, driving the T-bar 218 and the drop tube 221 to reciprocate. This causes the drop tube 221 to swing and eject the mixture into the pit. The screed plate 23 then scrapes the mixture flat, and the leveling column 21 rotates and rolls the scraped mixture, achieving pit paving and leveling. Furthermore, by employing the arc-top groove 16, when the limiting rod 226 is at either end of the arc-top groove 16, the paving and leveling assembly 2 is positioned at either end of the pit, positioning the power block 213 relatively below the straight groove 219. As the power block 213 moves, the drop tube 221 swings to its maximum angle, matching the larger angle of the pit edge, ensuring a better fit between the mixture and the existing road surface.

[0049] Although the above describes the specific implementation methods of the invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
