Description

Technical Field

[0001] This invention relates to an asphalt pavement repair device and method, belonging to the field of pavement construction technology. Background Technology

[0002] Asphalt binders enhance the ability of paving aggregates to resist damage to the road surface from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable road surface. Therefore, asphalt pavement is a widely used high-grade pavement in road construction.

[0003] Traditional asphalt pavements will deteriorate after prolonged use, mainly manifested as cracks and potholes. Potholes are usually repaired using cold asphalt. In the filling process, cold asphalt is first laid at the bottom of the pothole, and then a special vehicle or device with rollers is used to repeatedly roll the filled pavement. However, because the cold asphalt cannot be evenly laid at the bottom of the pothole during the laying process, many gaps and holes will appear in the asphalt, which is not conducive to the subsequent rolling construction of the filled pavement. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an asphalt pavement repair device and method, which solves the problem in the prior art that when repairing deep potholes on the road, the cold asphalt cannot be evenly laid at the bottom of the pothole, resulting in many gaps and holes in the asphalt.

[0005] The technical problem to be solved by the present invention is achieved by the following technical solution: an asphalt pavement repair device, comprising...

[0006] The support structure is a box-shaped structure with an opening on the top.

[0007] The extension body, part of the frame, is fixed to one side of the support body, and the connection ends of the extension body and the support body are interconnected.

[0008] An adjustment mechanism is located at the connection between the extension body and the support body, and the adjustment mechanism is equipped with...

[0009] The adjustment bracket is connected to the adjustment mechanism.

[0010] The connector is mounted on the adjusting frame and slides within the adjusting frame.

[0011] The flip-up plate, located inside the support structure, is connected to the connector.

[0012] The flipping mechanism is located on the inner bottom wall of the support body, and it abuts against the end of the flipping plate away from the connecting piece.

[0013] The rolling roller is horizontally positioned inside the extension body and is mounted on the adjustment frame. The outer curved surface of the rolling roller extends to the outside of the extension body. The shortest line connecting the end of the flip plate connected to the connector and the end of the flip plate abutting against the flipping mechanism is perpendicular to the axis of the rolling roller.

[0014] The adjustment mechanism is used to adjust the position of the adjustment frame and change the tilt of the flip plate, while the flipping mechanism is used to flip the flip plate clockwise and counterclockwise along the connection end with the connector.

[0015] By adopting the above technical solution, the flipping mechanism causes the end of the flipping plate away from the connector to flip back and forth at a certain angle, so that the flipping plate is in motion. When the repair material is poured onto the flipping plate, the repair material can move slowly and evenly toward the direction of the extension body, so that the material can fall evenly onto the ground at the repair location after falling off the flipping plate. As the support body is manually pulled at a uniform speed on the road surface, the repair material can be evenly laid on the road at the repair location, thereby avoiding the situation where large voids are generated inside the material due to uneven laying of the material at the repair location, which facilitates the subsequent compaction of the repair material.

[0016] The present invention is further configured such that: the adjusting mechanism includes

[0017] An adjusting rotating rod is located at the connection between the support body and the extension body, and the adjusting rotating rod is rotatably mounted on the upper side of the extension body.

[0018] One end of the threaded rod is rotatably connected to the lower frame of the extension body, and the other end of the threaded rod is fixedly connected to the adjusting rotating rod. The adjusting frame is threadedly connected to the threaded rod.

[0019] By adopting the above technical solution, the user rotates the adjusting rod to drive the threaded rod to rotate. Since the adjusting frame is threadedly connected to the threaded rod and the threaded rod cannot rotate, the adjusting frame moves vertically. Since the flipping plate is connected to the adjusting frame through the connecting piece, the end of the flipping plate moves vertically. Since the other end of the flipping plate abuts against the flipping mechanism, the tilt of the flipping plate will change, thereby achieving the purpose of adjusting the tilt of the flipping plate. This, in turn, increases the speed at which the repair material moves on the flipping plate, improving the convenience of controlling the rate at which the repair material fills the ground.

[0020] The invention is further configured such that: the adjusting frame is L-shaped, the vertical end of the L-shaped adjusting frame is connected to the threaded rod, a sliding channel is provided on the adjusting frame, the sliding channel extends along the shape of the adjusting frame, the sliding channel passes through the adjusting frame in the horizontal direction, one end of the connecting member is set in the sliding channel, the other end of the connecting member is rotatably connected to the flip plate, and the horizontal end of the L-shaped adjusting frame extends away from the support and the end is connected to the rolling wheel.

[0021] By adopting the above technical solution, the adjustment frame is set in an L shape with the horizontal end facing away from the support body, and the end is connected to the roller. At this time, there is a large space between the roller and the support body, which avoids the situation where the repair material falling from the flip plate sticks to the roller and cannot fall because the distance between the support body and the roller is too small, thus improving the smoothness of the repair material falling.

[0022] The present invention is further configured such that: the flipping mechanism includes

[0023] The fixing block is fixed to the inner bottom wall of the support body.

[0024] The sliding cavity is located within the fixed block, with its opening facing upwards.

[0025] The abutment sliding rod is set inside the sliding cavity, and slides up and down along the sliding cavity.

[0026] A drive structure is located below the sliding rod, and the drive structure is used to drive the sliding rod to slide.

[0027] By adopting the above technical solution, the driving structure drives the sliding rod to slide up and down. During the up and down sliding process, the sliding rod lifts the flipping plate. When the flipping plate flips to its maximum angle, the sliding rod begins to move downward and the flipping plate resets and flips under the action of gravity, thereby achieving the effect of continuously flipping the flipping plate back and forth.

[0028] The present invention is further configured such that: the driving structure includes

[0029] The drive motor is fixed to the vertical surface of the fixed block.

[0030] The first cam is rotatably mounted in the sliding cavity. The first cam is powered by the drive motor, and the curved surface of the first cam abuts against the sliding rod.

[0031] By adopting the above technical solution, after the drive motor starts, it drives the first cam to rotate. Since the curved surface of the first cam abuts against the sliding rod, the sliding rod moves up and down under the action of the rotation of the first cam and its own gravity, thereby achieving the purpose of continuously lifting the flipping plate.

[0032] The present invention is further configured such that: the connector includes

[0033] A sliding connecting rod is included, with one end extending into the sliding channel and the other end rotatably connected to the tilting plate.

[0034] The locking bolt is located at the end of the sliding connecting rod away from the flip plate. The locking bolt is located on the side of the adjusting frame away from the flip plate. The locking bolt is internally connected to the sliding connecting rod and abuts against the outer surface of the adjusting frame.

[0035] By adopting the above technical solution, the sliding connecting rod slides in the sliding channel. When the locking bolt is screwed into the sliding connecting rod, the contact pressure between the locking bolt and the surface of the adjusting frame increases, thereby increasing the friction between the flip plate and the locking bolt and the surface of the adjusting frame respectively. At this time, the position of the end of the flip plate connected to the sliding connecting rod can be fixed relative to the adjusting frame, which is beneficial to improving the stability of the flip plate during use.

[0036] The invention is further configured such that: the flip plate is provided with

[0037] The mounting cavity is located inside the flip plate.

[0038] The abutment rollers are rotatably mounted on opposite end walls of the mounting cavity. The axial direction of the abutment rollers is parallel to the axial direction of the rolling rollers, and the curved surface of the abutment rollers extends from the inside of the mounting cavity to above the flip plate.

[0039] The friction wheel is rotatably mounted on the inner wall of the mounting cavity at one end. The friction wheel is located outside the abutment wheel, and the outer curved surface of the friction wheel abuts against the outer curved surface of the abutment wheel. The axial directions of the friction wheel and the abutment wheel are parallel.

[0040] The second cam is coaxially fixed to the friction wheel, and is fixed at the end of the friction wheel away from the inner wall of the mounting cavity.

[0041] One end of the elastic plate is fixedly connected to the inner wall of the mounting cavity, and the other end of the elastic plate extends to the radially outer side of the second cam.

[0042] In this process, the second cam comes into contact with the elastic sheet during rotation, causing the elastic sheet to deform. After the elastic sheet deforms, it disengages from the second cam.

[0043] By adopting the above technical solution, when the flipping plate is in an inclined state and abuts against the flipping mechanism, when repair material is poured onto the flipping plate, the repair material slides on the flipping plate and contacts it, giving the flipping plate a rotational torque, thus causing the flipping plate to rotate. At this time, the flipping plate drives the friction wheel to rotate under the action of friction, which in turn drives the second cam to rotate. After the protruding part of the second cam abuts against the elastic plate, the elastic plate undergoes elastic deformation, causing the elastic plate to bend away from the second cam. When the second cam continues to rotate and the elastic plate disengages from the abutment, the elastic plate returns to its original position under elastic action. At this time, the elastic plate will vibrate, thus directly transmitting the vibration to the flipping plate, causing the flipping plate surface to vibrate slightly. In the above process, the flipping plate can achieve the effect of resisting... The purpose of this mechanism is to reduce the falling speed of materials on the tilting plate. Simultaneously, when the tilting plate rotates along the connecting member, the side of the tilting plate with the abutment wheel faces the rolling roller. At this point, the position of the tilting plate can be adjusted by changing the position of the connecting member within the sliding channel, thereby adjusting the relative position of the abutment wheel and the rolling roller. This allows the abutment wheel and the rolling roller to abut against each other. When the abutment wheel and the rolling roller are in contact, and the rolling roller is used to flatten the repaired road surface, the rolling roller rotates and, under the action of friction, drives the abutment wheel to rotate. Through this process, the tilting plate vibrates. Since the abutment wheel is facing downwards, the vibration of the tilting plate will shake off some of the repair material remaining on the tilting plate, preventing the repair material from remaining on the tilting plate for a long time, thus achieving the initial cleaning effect of the tilting plate.

[0044] The invention is further configured such that: a buffer box is fixedly installed on the side of the upper opening of the support body away from the extension body; an adjustment groove extending along the axial direction of the threaded rod is provided on the side of the support body facing the adjustment frame; the adjustment frame extends into the adjustment groove and slides against the adjustment groove.

[0045] By adopting the above technical solution, extending the adjustment frame into the adjustment groove can prevent the adjustment frame from rotating synchronously when the threaded rod rotates, and at the same time improve the stability of the adjustment frame during the axial movement along the threaded rod.

[0046] The present invention is further configured such that: a second rotating wheel group and a first rotating wheel group are respectively provided below the support body and below the extension body, the first rotating wheel group and the second rotating wheel group are axially aligned with the rolling wheel, and the first rotating wheel group and the second rotating wheel group are rotatably connected to the extension body and the support body respectively.

[0047] By adopting the above technical solution and setting up the first and second rotating wheel sets, the pulling force required by the user to pull the support and extension body can be reduced, thereby reducing the labor intensity of the user when repairing the road surface.

[0048] The method of using asphalt pavement repair equipment includes:

[0049] S1: Activate the flipping mechanism to make the flipping plate reciprocate from the side away from the connector;

[0050] S2: Pour repair material onto the flip-over plate;

[0051] S3: Pull the support body to move at the road repair location, so that the extension body passes through the road repair location completely;

[0052] S4: Flip the flip plate along the connector and close the flip mechanism. Use the adjustment mechanism to change the height of the connector, thereby adjusting the tilt of the flip plate to make the flip plate horizontal.

[0053] S5: Push the support body in the opposite direction to allow the rolling roller to pass through the repaired road surface.

[0054] By adopting the above technical solution, when repairing the road surface, there is no need to use an additional road roller to press the repaired area. At the same time, it can be ensured that the position of the repair material filling the road surface does not need to be manually changed during the repair process, which greatly improves the repair efficiency.

[0055] The beneficial effects of this invention are:

[0056] 1. The flipping mechanism causes the end of the flipping plate away from the connector to flip back and forth at a certain angle, so that the flipping plate is in motion. When the repair material is poured onto the flipping plate, the repair material can move slowly and evenly towards the direction of the extension body, so that the material can fall evenly on the ground to be repaired after falling from the flipping plate. As the support body is pulled at a constant speed by hand on the road surface, the repair material can be evenly laid on the road surface to be repaired, thereby avoiding the situation where large voids are formed in the interior of the material due to uneven laying of the material at the repair position, which facilitates the subsequent compaction of the repair material.

[0057] 2. The adjustment frame is L-shaped with its horizontal end facing away from the support body, and its end is connected to the roller. At this time, there is a large space between the roller and the support body, which avoids the situation where the repair material falling from the flip plate sticks to the roller and cannot fall because the distance between the support body and the roller is too small, thus improving the smoothness of the repair material falling.

[0058] 3. When the tilting plate flips along the connector, so that the side of the tilting plate with the abutment wheel faces the rolling roller, the position of the tilting plate can be adjusted by adjusting the position of the connector in the sliding channel. This adjusts the relative position of the abutment wheel and the rolling roller, allowing them to abut against each other. When the abutment wheel and the rolling roller are in contact, the rolling roller is used to flatten the repaired road surface. The rolling roller rotates and drives the abutment wheel to rotate under the action of friction. Through the above process, the tilting plate vibrates. Since the abutment wheel is facing downwards, the vibration of the tilting plate will shake off some of the repair material remaining on the tilting plate, preventing the repair material from remaining on the tilting plate for a long time and achieving the effect of initially cleaning the tilting plate.

[0068] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0069] like Figure 1-8 As shown, an asphalt pavement repair device includes a support body 10, an extension body 11, a rolling wheel 15, a tilting plate 30, a connector, an adjustment mechanism, and a tilting mechanism. The support body 10 is a box-shaped structure with an opening on the upper side, and its vertical cross-section is U-shaped. The extension body 11 is a rectangular frame and is fixed to one side of the U-shaped horizontal opening of the support body 10. The connection ends of the extension body 11 and the support body 10 are interconnected. The adjustment mechanism is directly fixed at the connection between the extension body 11 and the support body 10. Two sets of adjustment mechanisms are provided, located on the side end face of the U-shaped vertical wall of the support body 10 facing the extension body 11. An adjustment frame 22 is provided on the adjustment mechanism and is connected to the adjustment mechanism. The connector is slidably and rotatably mounted on the adjustment frame 22, and the connector can slide within the adjustment frame 22 along the shape extension direction of the adjustment frame 22. The flip plate 30 is located inside the support body 10, and one end of the flip plate 30 facing the two sets of adjustment mechanisms is rotatably connected to the connector. The flipping mechanism is located on the inner bottom wall of the support body 10, away from the extension body 11, and abuts against the end of the flip plate 30 away from the connector. The rolling roller 15 is horizontally arranged and located inside the extension body 11. The end of the rolling roller 15 is rotatably connected to the adjustment frame 22, and the outer curved surface of the rolling roller 15 extends to the outside of the frame structure below the extension body 11. The shortest line connecting the end of the flip plate 30 connected to the connector and the end of the flip plate 30 abutting against the flipping mechanism is perpendicular to the axis of the rolling roller 15.

[0070] The adjustment mechanism adjusts the vertical position of the adjustment frame 22 by moving the adjustment frame 22 up and down, thereby changing the height of one end of the flip plate 30, and thus achieving the purpose of adjusting the tilt of the flip plate 30. The flipping mechanism abuts against the flip plate 30, causing the flip plate 30 to flip along one end of the connecting member, thereby causing the flip plate 30 to undergo a small-angle reciprocating flipping motion.

[0071] like Figure 1-2As shown, the adjustment mechanism includes an adjustment rotating rod 20 and a threaded rod 21. The adjustment rotating rod 20 is rotatably mounted at the connection between the support body 10 and the extension body 11, and is located on the upper side of the extension body 11. One end of the threaded rod 21 is rotatably connected to the lower frame of the extension body 11, and the other end of the threaded rod 21 passes through the extension body 11 and extends to the adjustment rotating rod 20, where it is fixedly connected. The threaded rod 21 rotatably abuts against the extension body 11, and the adjustment frame 22 is threadedly connected to the threaded rod 21. The adjustment frame 22 is L-shaped, and its vertical L-shaped end is connected to the threaded rod 21 and simultaneously abuts against the side face of the U-shaped vertical wall of the support body 10 facing the extension body 11. The adjustment frame 22 has a sliding channel 23 extending along the shape of the adjustment frame 22. The horizontal cross section of the sliding channel 23 is convex and the small opening faces the flip plate 30. The sliding channel 23 passes through the adjustment frame 22 in the horizontal direction. One end of the connector is set in the sliding channel 23, and the other end of the connector is rotatably connected to the flip plate 30. The horizontal end of the adjustment frame 22, which is L-shaped, extends in the direction away from the support body 10 and the end is connected to the rolling wheel 15.

[0072] like Figure 5 and Figure 7 As shown, the flipping mechanism includes a fixed block 40, a sliding cavity 42, an abutting sliding rod 44, and a drive structure. The fixed block 40 is fixed to the inner bottom wall of the support body 10. The sliding cavity 42 is opened inside the fixed block 40 with its opening facing vertically upward. The abutting sliding rod 44 is slidably disposed inside the sliding cavity 42, and can slide up and down along the sliding cavity 42, with its end extending from the opening of the sliding cavity 42 to the outside. The drive structure includes a drive motor 41 and a first cam 43. The drive motor 41 is fixed to the vertical surface of the fixed block 40 and is located below the abutting sliding rod 44, with its axial direction extending horizontally. The first cam 43 is rotatably disposed inside the sliding cavity 42 and located below the abutting sliding rod 44. The first cam 43 extends axially into the sliding cavity 42 and is poweredly connected to the drive motor 41, with its outer curved surface always abutting against the lower end face of the abutting sliding rod 44.

[0073] like Figure 2As shown, the connector includes a locking bolt 24 and a sliding connecting rod 26. One end of the sliding connecting rod 26 extends into the sliding channel 23, and the end of the sliding connecting rod 26 inside the sliding channel 23 fits the internal contour of the sliding channel 23. The sliding connecting rod 26 can only slide within the sliding channel 23 along the extending direction of the sliding channel 23. The other end of the sliding connecting rod 26 extends to the outside of the adjusting frame 22 and is rotatably connected to the flip plate 30. The locking bolt 24 is located at the end of the sliding connecting rod 26 away from the flip plate 30. The locking bolt 24 is located on the side of the adjusting frame 22 away from the flip plate 30. The locking bolt 24 is inserted into the sliding connecting rod 26 and is threaded into the sliding connecting rod 26. The side of the locking bolt 24 facing the sliding connecting rod 26 abuts against the outer surface of the adjusting frame 22.

[0074] like Figure 1 and Figure 4As shown, the tilting plate 30 is provided with an abutment wheel 31, a mounting cavity 32, a second cam 33, an elastic plate 34, and a friction wheel 35. The mounting cavity 32 is located inside the tilting plate 30. The two ends of the abutment wheel 31 are rotatably mounted on the opposite end walls of the mounting cavity 32, and the axial direction of the abutment wheel 31 is parallel to the axial direction of the rolling wheel 15. The mounting cavity 32 has an opening facing upwards. The curved surface of the abutment wheel 31 passes through the opening of the mounting cavity 32, passes through the tilting plate 30, and extends above the tilting plate 30. The outer curved surface of the abutment wheel 31 abuts against the side wall of the opening of the mounting cavity 32. One end of the friction wheel 35 is rotatably mounted on the inner wall of the mounting cavity 32. The friction wheel 35 is located outside the abutment wheel 31, and the outer curved surface of the friction wheel 35 is in close contact with the outer curved surface of the abutment wheel 31. There is friction at the contact point between the friction wheel 35 and the abutment wheel 31. The axial direction of the friction wheel 35 is parallel to the axial direction of the abutment wheel 31. The second cam 33 is coaxially fixed to the friction wheel 35, and the second cam 33 is fixed to the end of the friction wheel 35 away from the inner wall of the mounting cavity 32. The elastic plate 34 is L-shaped, one end of the elastic plate 34 is fixedly connected to the inner wall of the mounting cavity 32, and the other end of the elastic plate 34 extends radially outward to the second cam 33 so that the protruding part of the outer curved surface of the second cam 33 can intermittently abut against the elastic plate 34, causing the elastic plate 34 to deform. A buffer box 14 is fixedly installed on the side of the upper opening of the support body 10 away from the extension body 11. The buffer box 14 can block some of the material falling onto the tilting plate 30, preventing the material from directly impacting the tilting plate 30 and protecting the normal use of the tilting plate 30. An adjustment groove 25 extending axially along the threaded rod 21 is opened on the side of the support body 10 facing the adjustment frame 22. The adjustment frame 22 extends into the adjustment groove 25 and slides against the adjustment groove 25. A second rotating wheel set 13 and a first rotating wheel set 12, with their axes aligned on the same horizontal plane, are respectively provided on the side of the support body 10 away from the extension body 11 and the side of the extension body 11 away from the support body 10. The first rotating wheel set 12 and the second rotating wheel set 13 are axially aligned with the rolling roller 15. The first rotating wheel set 12 and the second rotating wheel set 13 are rotatably connected to the outer end faces of the extension body 11 and the support body 10, respectively, through support blocks or support plates. The first rotating wheel set 12 and the second rotating wheel set 13 have a conventional structure, consisting of a rotating shaft and two wheels.

[0075] like Figure 6 As shown, after the flip plate 30 flips along the connecting piece, it abuts against the rolling roller 15. At this time, several counterweight plates 50 are vertically stacked on the flip plate 30. The counterweight plates 50 are used to increase the pressure of the rolling roller 15 on the ground.

[0076] The flipping mechanism causes the end of the flipping plate 30 away from the connector to flip back and forth at a certain angle, so that the flipping plate 30 is in motion. When the repair material is poured onto the flipping plate 30, the repair material can move slowly and evenly toward the extension body 11, so that the material can fall evenly onto the ground at the repair position after falling off the flipping plate 30. As the support body 10 is manually pulled at a uniform speed on the road surface, the repair material can be evenly laid on the road surface at the repair position, thereby avoiding large voids in the repair position and facilitating subsequent compaction of the repair material.

[0077] The user rotates the adjusting rod 20 to drive the threaded rod 21 to rotate. Since the adjusting frame 22 is threadedly connected to the threaded rod 21 and the threaded rod 21 cannot rotate, the adjusting frame 22 moves vertically. Since the flipping plate 30 is connected to the adjusting frame 22 through the connecting piece, the end of the flipping plate 30 moves vertically. Since the other end of the flipping plate 30 abuts against the flipping mechanism, the tilt of the flipping plate 30 will change, thereby achieving the purpose of adjusting the tilt of the flipping plate 30, and thus achieving the speed at which the repair material moves on the flipping plate 30, improving the convenience of controlling the rate at which the repair material fills to the ground.

[0078] The adjusting frame 22 is L-shaped with its horizontal end facing away from the support body 10, and its end is connected to the rolling roller 15. At this point, there is a large space between the rolling roller 15 and the support body 10, thus preventing repair material falling from the flipping plate 30 from sticking to the rolling roller 15 due to insufficient distance between the support body 10 and the rolling roller 15, improving the smoothness of the repair material's descent. The drive structure drives the abutment sliding rod 44 to slide up and down. During the up-and-down sliding process, the abutment sliding rod 44 lifts the flipping plate 30. When the flipping plate 30 reaches its maximum flipping angle, the abutment sliding rod 44 begins to move downwards, and the flipping plate 30 resets and flips under gravity, thus achieving the effect of continuously flipping the flipping plate 30 back and forth.

[0079] After the drive motor 41 starts, it drives the first cam 43 to rotate. Since the curved surface of the first cam 43 abuts against the sliding rod 44, the sliding rod 44 moves up and down under the action of the rotation of the first cam 43 and its own gravity, thereby achieving the purpose of continuously lifting the flip plate 30.

[0080] The sliding connecting rod 26 slides within the sliding channel 23. When the locking bolt 24 is screwed into the sliding connecting rod 26, the contact pressure between the locking bolt 24 and the surface of the adjusting frame 22 increases, thereby increasing the friction between the flip plate 30 and the locking bolt 24 and the surface of the adjusting frame 22. At this time, the end of the flip plate 30 connected to the sliding connecting rod 26 can be fixed relative to the adjusting frame 22, which helps to improve the stability of the flip plate 30 during use. When the flip plate 30 is in an inclined state and abuts against the flipping mechanism, when repair material is poured onto the flip plate 30, the repair material slides on the flip plate 30 and contacts the flip plate 30, giving the flip plate 30 a rotational torque, thereby causing the flip plate 30 to rotate. At this time, the flip plate 30 drives the friction wheel 35 to rotate under the action of friction, thereby causing the friction wheel 35 to drive the second cam 33 to rotate. When the protruding part of the second cam 33 abuts against the elastic plate 34, the elastic plate 34 undergoes elastic deformation, thereby causing the elastic plate 34 to bend away from the second cam 33. When the second cam 33 continues to rotate and the elastic plate 34 disengages from the contact point, the elastic plate 34 returns to its original position under elastic action. At this time, the elastic plate 34 will vibrate, thereby directly transmitting the vibration to the flip plate 30, causing a slight vibration on the surface of the flip plate 30.

[0081] During the above process, the tilting plate 30 can impede the rate at which materials fall up and down on the tilting plate 30. Simultaneously, when the tilting plate 30 is tilted along the connecting member, the side of the tilting plate 30 with the abutment wheel 31 faces the rolling roller 15. At this time, the position of the tilting plate 30 can be adjusted by adjusting the position of the connecting member within the sliding channel 23, thereby adjusting the relative position of the abutment wheel 31 and the rolling roller 15, allowing them to abut against each other. After the abutment wheel 31 and the rolling roller 15 abut against each other, when the rolling roller 15 is used to flatten the repaired road surface, the rolling roller 15 rotates and, under the action of friction, drives the abutment wheel 31 to rotate. Through this process, the tilting plate 30 vibrates. Since the abutment wheel 31 faces downwards, the vibration of the tilting plate 30 will shake off some of the repair material remaining on the tilting plate 30, preventing the repair material from remaining on the tilting plate 30 for a long time, achieving the effect of initially cleaning the tilting plate 30.

[0082] The adjustment frame 22 extends into the adjustment groove 25 to prevent synchronous rotation of the adjustment frame 22 when the threaded rod 21 rotates, and at the same time improves the stability of the adjustment frame 22 during the axial movement along the threaded rod 21. By setting the first rotating wheel group 12 and the second rotating wheel group 13, the pulling force required by the user to pull the support body 10 and the extension body 11 can be reduced, thereby reducing the labor intensity of the user when repairing the road surface.

[0083] The method of using asphalt pavement repair equipment includes:

[0084] S1: Start the drive motor 41 in the flipping mechanism to drive the first cam 43 to rotate, so that the side of the flipping plate 30 away from the connecting piece is lifted by the sliding rod 44, thereby causing the flipping plate 30 to start flipping back and forth at a small angle.

[0085] S2: The user directly pours repair material onto the flip plate 30;

[0086] S3: The user manually pulls the support 10 to move in a straight line at the road repair position, so that the extension body 11 passes through the road repair position completely;

[0087] S4: Close the flipping mechanism and flip the flipping plate 30 away from the flipping mechanism along the connector. Use the adjustment mechanism to change the vertical height of the connector and change the position of the connector in the adjustment frame 22. This adjusts the height of one side of the flipping plate 30 to be the same as the height of the other side of the flipping plate 30, so that the flipping plate 30 is in a horizontal state and the lowest side of the rolling roller 15 is lower than the lowest side of the first rotating wheel group 12 and the second rotating wheel group 13.

[0088] S5: Several counterweight plates 50 are stacked and installed on the horizontal flip plate 30 to increase the pressure of the rolling roller 15 on the ground.

[0089] S6: The user pushes the support body 10 to move in the opposite direction, so that the roller 15 repeatedly compacts the road repair material by passing through the road surface multiple times. This achieves the effect of not needing to use a road roller to press the road surface during road repair, and at the same time, it ensures that the position of the repair material filling the road surface does not need to be manually changed during the repair process, which greatly improves the repair efficiency.
