DETAILED DESCRIPTION

[0032] See also Figure 1-Figure 10 In an embodiment of the present invention, an asphalt pavement repair and leveling device and a leveling method include a shell 1, first brackets 2 are provided at both ends of the bottom of the shell 1, moving wheels are provided at the bottom of the first bracket 2, leveling rollers 3 are symmetrically provided along the center of the bottom of the shell 1, second brackets 4 are provided at both ends of the leveling roller 3, the top of the second bracket 4 is fixedly connected to the bottom of the shell 1, the leveling roller 3 is installed below the shell 1 through the second bracket 4, and the leveling roller 3 and the second bracket 4 are rotatably connected, an auxiliary roller 5 is provided at the bottom of the second bracket 4, and the auxiliary roller 5 is provided at the end of the leveling roller 3, and a transmission assembly is provided at the top of the auxiliary roller 5, when the first bracket 2 moves toward the shell 1, the first bracket 2 drives the auxiliary roller 5 to move downward through the transmission assembly, and when the leveling roller 3 rotates, the leveling roller 3 drives the auxiliary roller 5 to rotate through the transmission assembly.

[0033] In addition, preferably, the auxiliary roller 5 can be separately arranged on a group of second brackets 4, or the auxiliary roller 5 can be arranged on two groups of second brackets 4. A driving component for driving the first bracket 2 to move and retract into the shell 1 is arranged in the shell 1. The driving component is preferably a driving cylinder. In the initial state, the first bracket 2 extends out of the bottom of the shell 1 at the maximum, and then the leveling roller 3 is moved away from the ground through the moving wheel. Therefore, when the leveling roller 3 is not needed to level the asphalt pavement, the leveling roller 3 does not work, thereby reducing the wear of the leveling roller 3 and extending the service life of the leveling roller 3. When the asphalt pavement needs to be leveled, the driving cylinder is started to drive the first bracket 2 to move and retract in the direction of the shell 1, so that the leveling roller 3 is in contact with the ground, and then the asphalt pavement is leveled by the leveling roller 3. Of course, the leveling roller 3 can be driven by manpower or a motor. If it is driven by a motor, the specific related structures and working principles are all existing technologies and will not be described in detail here.

[0034] In actual use, when the leveling roller 3 is used to level one side of the asphalt pavement, the side of the auxiliary roller 5 close to the leveling roller 3 corresponds to the vertical edge of the pavement edge relative to the ground. Since the edge of the asphalt pavement is inevitably uneven when laying asphalt, the auxiliary roller 5 is set vertically relative to the ground, so that when the auxiliary roller 5 moves downward, it can better adapt to and level the vertical edge of the asphalt pavement. When the first bracket 2 is started to move upward and shrink in the shell 1, the movement of the first bracket 2 will drive the auxiliary roller 5 to move downward through the transmission component, so that the auxiliary roller 5 is parallel to the vertical edge of the asphalt pavement edge, and the auxiliary roller 5 and the leveling roller 3 remain vertical, that is, the surface of the auxiliary roller 5 in contact with the vertical edge of the asphalt pavement is in contact with the surface of the bottom of the leveling roller 3 in contact with the asphalt pavement. In this way, when the leveling work is performed, the asphalt at the corners of the asphalt pavement will not be due to the gap between the auxiliary roller 5 and the leveling roller 3, which will cause the asphalt at the edge of the pavement to protrude upward from the entire pavement due to the leveling action of the auxiliary roller 5.

[0035] See also Figure 1-Figure 3Preferably, the transmission assembly includes a rotating shaft 8; a slot 7 is provided on the side of the second bracket 4 away from the leveling roller 3, the rotating shaft 8 is rotatably embedded in the slot 7, the top of the rotating shaft 8 is rotatably connected to the shell 1, the auxiliary roller 5 is slidably arranged at the bottom of the rotating shaft 8, a first bevel gear 9 is arranged above the auxiliary roller 5, the first bevel gear 9 is fixedly sleeved on the outer side wall of the rotating shaft 8, and the first bevel gear 9 is arranged between the second bracket 4 and the auxiliary roller 5, and the end of the leveling roller 3 close to the rotating shaft 8 is fixedly provided with a second bevel gear 10 that is transmission-engaged with the first bevel gear 9; in actual use, the second bracket 4 is provided with a The arc groove of the second bevel gear 10 rotates, and when the leveling roller 3 rotates, the leveling roller 3 drives the second bevel gear 10 to rotate, and the rotation of the second bevel gear 10 drives the first bevel gear 9 to rotate, and the rotation of the first bevel gear 9 drives the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 drives the auxiliary roller 5 to rotate. The auxiliary roller 5 rotates to achieve the leveling of the vertical edge of the asphalt pavement edge, avoiding the uneven asphalt at the edge of the pavement, which affects the overall appearance and driving comfort of the pavement, reduces the service life of the pavement, etc., and also requires separate cutting work for the uneven edge of the asphalt pavement.

[0036] Further, preferably, an air groove 802 is provided at the center of the rotating shaft 8, and a vertical groove 801 connected to the air groove 802 is provided on the side wall of the bottom end of the rotating shaft 8. The vertical groove 801 is symmetrically arranged along the center of the side wall of the rotating shaft 8. A piston plate 15 is fixedly arranged on the top of the inner wall of the auxiliary roller 5. The piston plate 15 slides through the vertical groove 801 and the air groove 802, that is, the auxiliary roller 5 is slidably connected to the rotating shaft 8 through the sliding cooperation of the piston plate 15 with the vertical groove 801 and the air groove 802. A piston column 22 sealed and slidably connected to the air groove 802 is fixedly arranged at the center of the piston plate 15. In actual use, when gas is injected into the air groove 802, at the pressure of Under the action, the piston column 22 moves toward the auxiliary roller 5, that is, moves downward. The downward movement of the piston column 22 pushes the piston plate 15 to move downward, and then the auxiliary roller 5 moves downward on the periphery of the rotating shaft 8. In this way, when the leveling roller 3 performs leveling work on the edge of the asphalt pavement, in the process of the leveling roller 3 moving relative to the ground, the auxiliary roller 5 moves downward synchronously and corresponds to the vertical side of the edge of the pavement, so that the vertical surface of the edge of the pavement can be leveled. When negative pressure is generated in the air groove 802 above the piston column 22, the piston column 22 will move upward and reset, and then the piston plate 15 and the auxiliary roller 5 will move and reset.

[0037] See also Figure 7 , Fig.10Preferably, an installation cavity is provided on the inner wall of the shell 1 at a position corresponding to the first bracket 2, that is, the installation cavity is symmetrically arranged along the center of the shell 1, and corresponds to the two groups of first brackets 2 respectively, a support plate 23 is fixedly provided in the middle of the installation cavity, a telescopic tube 19 is fixedly provided at the bottom of the support plate 23, an airbag 20 is fixedly provided on the top of the support plate 23, a through hole is provided in the center of the support plate 23, the telescopic tube 19 and the airbag 20 are connected through the through hole, and a spring is provided between the top of the airbag 20 and the installation cavity, the bottom of the telescopic tube 19 is elastically connected to the top of the first bracket 2, and the through hole and the air groove 802 are connected through the connecting tube 21.

[0038] It should be noted that: an extension plate is elastically provided on the top side wall of the first bracket 2 and is fixedly connected to the bottom of the telescopic tube 19, and a baffle is fixedly provided on the top of the airbag 20, a spring between the airbag 20 and the installation cavity is provided above the baffle, and the baffle is slidingly fitted with the inner wall of the installation cavity, a connecting tube 21 is provided in the side wall of the outer shell 1, and one end of the connecting tube 21 close to the support plate 23 passes through the side wall of the support plate 23 and is connected to the through hole, and the end of the connecting tube 21 away from the support plate 23 is sealed and rotatably connected to the top of the rotating shaft 8.

[0039] During actual use, in the initial state when the moving wheel contacts the ground, the telescopic tube 19 is in an expanded state and the airbag 20 is in a contracted state. At this time, the air groove 802 is in a negative pressure state, that is, the auxiliary roller 5 is placed within the height range of the end of the leveling roller 3 through the action of the piston column 22. Of course, in order to prevent the auxiliary roller 5 from protruding out of the height range of the end of the leveling roller 3 in the initial state due to unstable negative pressure, thereby affecting the subsequent asphalt leveling work, a spring may be provided between the piston column 22 and the inner wall of the rotating shaft 8, so that in the initial state, the piston column 22 prompts the auxiliary roller 5 to be placed within the height range of the end of the leveling roller 3 under the action of the spring; when the first bracket 2 is started to move toward the outer shell 1 to allow the leveling roller 3 to contact the ground, the movement of the first bracket 2 will pass through the extension plate The telescopic tube 19 is compressed, and the gas in the telescopic tube 19 is transported to the connecting tube 21 and the airbag 20 through the through hole. Since a spring is provided on the top of the airbag 20, the gas will first be transported to the air groove 802 through the connecting tube 21, and the gas will push the piston column 22 to move downward. The piston column 22 moves through the piston plate 15 to move the auxiliary roller 5 downward. When the auxiliary roller 5 cannot move, the gas will be transported to the airbag 20 to expand the airbag 20. Conversely, when the first bracket 2 moves and resets, the telescopic tube 19 expands and resets, and the gas in the air groove 802 and the airbag 20 is transported to the telescopic tube 19 to reset, and the airbag 20 is reset, and the piston column 22 moves and resets. The piston column 22 moves and resets, and the auxiliary roller 5 moves and resets.

[0040] See also Figure 4-Figure 8Preferably, a support block 12 is slidably provided at the bottom center of the auxiliary roller 5, a ball 11 is movably embedded at the bottom of the support block 12, a second fixing plate 14 is symmetrically fixedly provided along the center of the top periphery of the support block 12, and the second fixing plate 14 is elastically connected to the bottom of the inner wall of the auxiliary roller 5 through a spring. In actual use, in the initial state where the leveling roller 3 is not in contact with the ground, the bottom height of the auxiliary roller 5 is higher than the bottom height of the leveling roller 3, and the support block 12 is in a state of protruding from the bottom of the auxiliary roller 5 under the action of the second fixing plate 14 and the corresponding spring, so that The ball 11 protrudes from the bottom of the auxiliary roller 5. When the first bracket 2 moves toward the shell 1, the auxiliary roller 5 moves downward through the action of the transmission component, thereby causing the support block 12 and the ball 11 to move downward and allow the ball 11 to contact the ground. In this way, the bottom of the auxiliary roller 5 is avoided from directly contacting the ground, which causes the end of the auxiliary roller 5 to be severely worn when the subsequent leveling roller 3 rotates to drive the auxiliary roller 5 to rotate. The provision of the ball 11 enables the auxiliary roller 5 to contact the ground through the ball 11 after moving downward, thereby extending the service life of the auxiliary roller 5.

[0041] See also Figure 6 , Fig. 9 Preferably, the inner wall of the auxiliary roller 5 is elastically connected to a mounting plate 16 through a spring, and the mounting plate 16 is symmetrically arranged along the center of the auxiliary roller 5. A limiting column 17 is fixedly arranged on one side of the mounting plate 16 close to the rotating shaft 8, and a plurality of groups of limiting columns 17 are arranged in an array along the vertical direction of the mounting plate 16. A limiting block 18 corresponding to the mounting plate 16 is fixedly arranged on the outer side wall of the bottom end of the rotating shaft 8, and a limiting hole 181 slidably matched with the limiting column 17 is arranged at one end of the limiting block 18 close to the mounting plate 16. In actual use, a groove slidably matched with the limiting block 18 is arranged on the inner wall of the auxiliary roller 5, and a semicircular structure is arranged at one end of the limiting column 17 close to the limiting block 18, which improves the fault tolerance of the limiting column 17 and the limiting hole 181, and the interval between two adjacent groups of limiting columns 17 is greater than the side wall distance between the two ends of the limiting hole 181 and the upper and lower sides of the end of the limiting block 18.

[0042] Furthermore, preferably, a first fixing plate 13 is fixedly provided symmetrically along the center on the outer periphery of the top end of the support block 12, and the positions of the first fixing plate 13 and the limit block 18 are arranged correspondingly, and the first fixing plate 13 and the second fixing plate 14 are arranged in a cross-shaped structure on the outer periphery of the support block 12, and a trigger plate is fixedly connected to the bottom of the mounting plate 16, and the end of the trigger plate away from the mounting plate 16 is slidably connected to the inner wall of the auxiliary roller 5 and extends into the groove, and the end of the trigger plate close to the mounting plate 16 is provided with an inclined surface facing the limit block 18, and the mounting plate 16 and the trigger plate are slidably matched. In actual use, when the trigger plate moves and extends into the groove, the top end of the inclined surface thereon is located on the outer side of the end of the mounting plate 16 away from the support block 12, so that when the mounting plate 16 moves downward, the trigger plate can be squeezed and pushed in the direction away from the support block 12 by slidingly matching with the inclined surface of the trigger plate.

[0043] When in use, in the initial state, the auxiliary roller 5 is close to the bottom of the second bracket 4, and the support block 12 protrudes from the bottom of the auxiliary roller 5 under the action of the corresponding spring, so that the first fixed plate 13 and the second fixed plate 14 are in contact with the bottom of the inner wall of the auxiliary roller 5. At this time, the first fixed plate 13 pushes the trigger plate away from the groove, and makes the mounting plate 16 away from the limit block 18, so that the limit column 17 is separated from the limit hole 181; at this time, after the first bracket 2 moves toward the shell 1, the auxiliary roller 5 moves downward through the action of the transmission component, and the auxiliary roller 5 moves downward to push the ball 11 and the support block 12 to move. When the ball 11 contacts the ground, the ball 11 pushes the support block 12 to move relatively toward the auxiliary roller 5, so that the first fixed plate 13 moves in the auxiliary roller 5 toward the direction of the limit block 18 to separate from the trigger plate. When the first fixed plate 13 is separated from the trigger plate, the mounting plate 16 moves in the direction of the limit block 18 under the action of the corresponding spring, and then pushes the limit column 17 to move into the limit hole 181, completing the limitation of the limit block 18, that is, the relative position limitation between the rotating shaft 8 and the auxiliary roller 5, avoiding the auxiliary roller 5 having the force of the transmission component to always move downward, resulting in the problem that the position of the auxiliary roller 5 is unstable and easily causes damage due to collision; when the first bracket 2 is moved and reset, the leveling roller 3 is away from the ground, and then the auxiliary roller 5 is away from the ground. At this time, the ball 11 and the support block 12 move and reset in the direction away from the auxiliary roller 5, so that the first fixed plate 13 slides with the trigger plate again, and then the mounting plate 16 is pushed to move in the direction away from the limit block 18, so that the limit column 17 is separated from the limit hole 181, thereby releasing the relative limitation between the rotating shaft 8 and the auxiliary roller 5, and then the auxiliary roller 5 moves and resets for the next use.

[0044] See also Figure 1 , Figure 2Preferably, a cleaning belt 6 is rotatably arranged between the two groups of second brackets 4, and the end of the cleaning belt 6 is slidably connected to the side wall of the second bracket 4, the end of the cleaning belt 6 is sleeved on the periphery of the rotating shaft 8, the cleaning belt 6 is arranged above the top of the leveling roller 3, and the bottom of the cleaning belt 6 is provided with bristles that contact the surface of the leveling roller 3. In actual use, when only one group of second brackets 4 is provided with a transmission assembly and an auxiliary roller 5, the cleaning belt 6 passes through one end of the second bracket 4 and is sleeved on the periphery of the rotating shaft 8, and when the two groups of second brackets 4 are provided with a transmission assembly and an auxiliary roller 5, the two ends of the cleaning belt 6 still keep one end sleeved on the periphery of a group of rotating shafts 8, that is, the cleaning belt 6 always remains driven by a group of rotating shafts 8; in this way, when in use, when the rotating shaft 8 rotates, the rotating shaft 8 will drive the cleaning belt 6 to rotate, and the cleaning belt 6 rotates to clean the surface of the leveling roller 3 through the bristles that are in contact with the surface of the leveling roller 3, avoiding the presence of impurities thereon that affect the quality of the asphalt pavement leveling work, and avoiding manual cleaning.
