Description

Technical Field

[0001] This invention relates to the field of road construction equipment technology, specifically to a road and bridge construction leveling device. Background Technology

[0002] Currently, during highway bridge construction, it is necessary to smooth the surface of the poured concrete to meet the requirements for flatness. Smoothing devices are usually used to smooth the concrete surface. As the core equipment for concrete surface treatment, the smoothing device's function is to compact, raise the slurry, and eliminate defects such as honeycomb and pitting on the concrete surface during the initial setting stage through mechanical or manual means, ultimately forming a flat, dense, and smooth surface. The main types include concrete smoothing machines, laser screed machines, and road smoothing pavers.

[0003] When smoothing roads, a two-roller auger paver is usually used. The auger distributes the material, then a vibrating roller is used to compact the concrete. Finally, a flattening roller smooths the road surface. However, after the concrete is compacted, the aggregate sinks and the slurry floats to the top, which may cause depressions in some areas. When the flattening roller squeezes the concrete, it will squeeze the concrete to flow, but the flow range is small and it may be difficult to fully fill the depressions, affecting the smoothness of the road. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a road and bridge construction leveling device, including a support frame, wheel frames fixedly connected to the left and right sides of the support frame, and a drive motor fixedly connected to the top of the support frame;

[0005] The frame structure has a translation component fixedly installed on its side wall and a smoothing component rotatably installed on its inner wall. The smoothing component is used to smooth the road surface.

[0006] A leveling mechanism, installed at the bottom of a frame mechanism, is used to fill depressions in the road surface; and

[0007] The flattening mechanism, located at the bottom of the frame mechanism, is used to press the road edge;

[0008] The bottom of the support frame is equipped with a vibrating frame, and the top of the vibrating frame is fixedly connected with eight spring rods. The outer walls of the eight spring rods are slidably connected to the inner wall of the support frame, and the outer walls of the support frame are fixedly connected with eight limiting frames.

[0009] When the road needs to be smoothed, the smoothing component is moved on the road by the translation component, and then the road surface is smoothed by the smoothing component. After that, the leveling mechanism increases the flow range of concrete, which allows the surrounding concrete to migrate more fully to the depressions and fill the depressions on the road surface. Finally, the compaction mechanism compacts the concrete at both ends of the road.

[0010] Preferably, the frame structure includes:

[0011] A translation component is fixedly installed on the side wall of the translation component and the side wall of the support frame, and is used to drive the frame mechanism to move;

[0012] The smoothing component is rotatably mounted on the inner wall of the support frame via a rotating component, and is used to smooth the road surface.

[0013] The rotating component includes a bidirectional spiral auger rotatably connected to the inner wall of the support frame, and a toothed chain assembly is fixedly connected to the outer wall of the bidirectional spiral auger.

[0014] When smoothing the road, the smoothing component moves along the road surface via the translation component, and then the smoothing component smooths the road surface.

[0015] Preferably, the leveling mechanism includes:

[0016] The vibratory assembly is slidably installed on the inner wall of the support frame for vibrating deep concrete.

[0017] The reciprocating assembly is fixedly mounted on the side wall of the support frame by fasteners to increase the flow range of concrete.

[0018] The fasteners include a second concave-convex ring fixedly connected to the left side of the support frame, and a first concave-convex ring fixedly connected to the right side of the support frame;

[0019] When the smoothing component smooths the road surface, it drives the vibrating component to vibrate, which vibrates the concrete deep inside and reduces the depressions on the concrete surface. Then, the reciprocating component pushes the concrete to flow, expanding the flow range of the concrete and allowing the surrounding concrete to migrate more fully to the depressions. This effectively prevents depressions from remaining after the concrete surface is smoothed, thus affecting the smoothness of the road surface.

[0020] Preferably, the flattening mechanism includes:

[0021] The extrusion assembly is slidably mounted on the inner wall of the support frame via a sliding member, and is used to extrude concrete at both ends of the road.

[0022] The sliding component includes two extrusion plates that are slidably connected to the inner wall of the support frame, and a connecting rod is rotatably connected to the top of each of the two extrusion plates;

[0023] The pushing component is slidably mounted on the inner wall of the support frame via the support member, and is used to squeeze out air bubbles on the concrete surface;

[0024] The support includes seven sliding rods slidably connected to the inner wall of the support frame, and a stepped block is provided at the bottom of the support frame;

[0025] As the reciprocating component moves back and forth, it causes the extrusion component to descend, extruding both ends of the road and inhibiting the loss of grout. This effectively prevents the concrete slurry from flowing to the edges during the reciprocating movement of the component, which would cause the concrete slurry to be lost at the road edges. The extrusion component also drives the pushing component to descend, expelling residual air bubbles on the concrete surface. This effectively prevents the surface of the concrete from being compacted by the smoothing component, which could leave tiny air bubbles on the surface after compaction. Direct compaction would cause these air bubbles to burst on the concrete surface, forming small depressions.

[0026] Preferably, the translation component includes a pulley set 1 disposed on the top of the support frame, the output end of the drive motor is fixedly connected to the side wall of the pulley set 1, a fixing block is fixedly connected to the top of the support frame, and the inner wall of the fixing block is rotatably connected to the outer wall of the pulley set 1.

[0027] Preferably, the smoothing component includes an eccentric rod rotatably connected to the inner wall of the support frame, a rotating rod rotatably connected to the inner wall of the support frame, and the outer wall of the pulley assembly one being fixedly connected to the inner wall of the toothed chain assembly one.

[0028] A second pulley assembly is fixedly connected to the outer wall of the first pulley assembly. The inner wall of the second pulley assembly is fixedly connected to the outer wall of the eccentric rod. A second toothed chain assembly is fixedly connected to the outer wall of the first pulley assembly. The inner wall of the second toothed chain assembly is fixedly connected to the outer wall of the rotating rod.

[0029] A vibrating roller is installed at the bottom of the support frame. The inner wall of the vibrating roller is rotatably connected to the outer wall of the eccentric rod. A flattening roller is installed at the bottom of the support frame. Two sliding rods are fixedly connected to the outer wall of the rotating rod. The outer walls of the two sliding rods are slidably connected to the inner wall of the flattening roller.

[0030] When road leveling is required, the power motor on the wheel frame is started, driving the pulley to rotate. Through gear chain transmission, the wheel rotates, which in turn moves the support frame on the road. Then, the drive motor is started, driving pulley group one to rotate. Pulley group one drives pulley group two, gear chain group one, and gear chain group two to rotate, which in turn rotates the bidirectional spiral auger, eccentric rod, and rotating rod. Since the eccentric part of the eccentric rod is in contact with the vibrating roller, a periodic unbalanced force is generated when the eccentric rod rotates. This unbalanced force is transmitted to the vibrating roller, causing it to oscillate back and forth. Simultaneously, when the rotating rod rotates, it drives the flattening roller to rotate through the sliding rod. When the bidirectional spiral auger rotates, the rotating blades push the concrete accumulated on the road laterally to both sides, spreading the concrete evenly along the width of the road. As the support frame moves along the road, the vibrating roller comes into contact with the concrete. The vibration of the vibrating roller compacts the concrete surface, making the concrete dense and removing some air bubbles. Then, the flattening roller comes into contact with the concrete, compacting and leveling the concrete surface.

[0031] Preferably, the vibrating assembly includes spring rod 2 slidably connected to the inner wall of the limiting frame, and the outer walls of the eight spring rods 1 are all slidably connected to the inner walls of the eight limiting frames;

[0032] During the oscillation of the vibrating roller, it comes into contact with the vibrating frame. The oscillation pushes the vibrating frame upward, which in turn causes spring rod one to rise, accumulating rebound force. When the vibrating roller separates from the vibrating frame, the rebound force of spring rod one is released, causing the vibrating frame to return to its original position. When the vibrating roller pushes the vibrating frame to the left, spring rod one squeezes spring rod two, accumulating rebound force, which causes the vibrating frame to oscillate back and forth, vibrating the frame. Since the vibrating frame is inserted into the concrete, it vibrates deep into the concrete, making the vibration more uniform.

[0033] Preferably, the reciprocating assembly includes a second connecting rod fixedly connected to the left side of the flattening roller, and a first connecting rod fixedly connected to the right side of the flattening roller;

[0034] When the flattening roller rotates, it causes the second connecting rod to separate from the protruding part of the second concave-convex ring. At this time, the first connecting rod is not in contact with the first concave-convex ring. As the flattening roller continues to rotate, the first connecting rod will come into contact with the protruding part of the first concave-convex ring and be squeezed, pushing the flattening roller to move towards the second concave-convex ring, causing the flattening roller to move laterally. Since the second connecting rod will separate from the protruding part of the second concave-convex ring, the flattening roller can move smoothly. When the first connecting rod separates from the protruding part of the first concave-convex ring, the second connecting rod will also come into contact with the protruding part of the second concave-convex ring, pushing the flattening roller to move towards the first concave-convex ring. This process repeats, allowing the flattening roller to move laterally back and forth. The flattening roller will then push the concrete to flow, increasing the flow range of the concrete. By vibrating the concrete to its depths, the vibration is made more uniform, reducing depressions on the concrete surface. Combined with the lateral movement of the flattening roller, the increased flow range of the concrete allows the surrounding concrete to migrate more fully to the depressions, achieving dynamic filling and effectively preventing depressions from remaining after the concrete surface is smoothed, which would affect the smoothness of the road surface.

[0035] Preferably, the extrusion assembly includes two annular grooves formed on the inner wall of the flattening roller, each annular groove has a push rod rotatably connected to its inner wall, the outer walls of the two push rods are slidably connected to the inner wall of the support frame, and the side walls of the two push rods are rotatably connected to the inner walls of the two connecting rods.

[0036] The bottom of the support frame is provided with two pressure plates. The top of each pressure plate is fixedly connected with two spring return rods. The four spring return rods are in pairs. The outer walls of the two pairs of spring return rods are slidably connected to the inner walls of the two pressure plates.

[0037] As the pressing roller moves towards the concave and convex rings, it drives the first push rod to move, causing the push rod on the right to rotate the connecting rod. The connecting rod then pushes the extrusion plate downwards, causing the spring return rod and the pressing plate to descend, bringing the pressing plate into contact with the concrete at one end of the road and compressing the concrete. The extrusion plate then compresses the spring return rod, increasing the extrusion pressure on the concrete. Simultaneously, the push rod on the left moves the extrusion plate and the pressing plate upwards, separating the pressing plate from the concrete at the other end of the road. This continues until the pressing roller moves towards the concave and convex rings, and the push rod on the left moves, pushing the extrusion plate and the pressing plate downwards, compressing the concrete. As the pressing roller pushes the concrete towards the edge of the road, the pressing plate descends, compressing the concrete and suppressing the loss of slurry at the edge. This effectively prevents the concrete slurry from flowing towards the edge during the reciprocating movement of the pressing roller, which would otherwise result in a thinner road edge.

[0038] Preferably, the pushing assembly includes a second pushing rod fixedly connected to the side wall of the left extrusion plate, the top of each step block is fixedly connected to the bottom of the seven sliding rods, and the top of the step block is fixedly connected to the bottom of the second pushing rod.

[0039] The bottom of the support frame is equipped with a flat plate, and the top of the flat plate is fixedly connected with eight spring return rods. The outer walls of the eight spring return rods are slidably connected to the inner wall of the support frame. The side walls of the vibrating frame are fixedly connected with eight transmission plates.

[0040] When the extrusion plate on the right descends, it drives the second push rod to descend as well. The push rod then drives the step block and sliding rod to descend. As the step block descends, the higher step of the step block comes into contact with the concrete. When the higher step of the step block applies pressure to the concrete surface, it first squeezes some air bubbles out of the concrete surface. Because there is a height difference between the lower and higher steps, the air bubbles will migrate towards the surface, avoiding applying pressure all at once and forcing the air bubbles into the concrete. This reduces the number of tiny air bubbles remaining on the concrete surface and effectively prevents the uneven contact between the vibrating roller and the concrete surface when the vibrating roller is compacting the surface concrete. This would prevent the air bubbles from bursting on the concrete surface and forming small depressions, resulting in a honeycomb surface on the road.

[0041] The present invention has the following beneficial effects:

[0042] (1) When using this invention, the support frame is moved on the road by the wheel frame. Then, the drive motor is started and the concrete is spread by the bidirectional spiral auger through the smoothing component. Then, the concrete surface is vibrated by the vibrating roller. Then, the flat roller will compact and level the concrete surface. When the vibrating roller swings, the vibrating frame is vibrated by the vibrating component, which will vibrate the deep part of the concrete, making the vibration more uniform. At the same time, when the flat roller rotates, the flat roller moves laterally back and forth through the reciprocating component, which increases the flow range of the concrete. By vibrating the deep part of the concrete, the depression on the concrete surface is reduced. With the lateral movement of the flat roller, the flow range of the concrete is increased, which allows the surrounding concrete to migrate more fully to the depression, effectively preventing the depression after the concrete surface is smoothed, which affects the smoothness of the road surface.

[0043] (2) When the pressing roller moves in the direction of the concave and convex rings, it will drive the push rod to move, so that the push rod on the right side pushes the connecting rod to rotate. Through the extrusion assembly, the pressing plate contacts the concrete at one end of the road and extrudes the concrete. When the pressing roller pushes the concrete to move towards the edge of the road, the pressing plate descends and extrudes the concrete, suppressing the loss of edge slurry. This effectively prevents the concrete slurry from flowing to the edge when the pressing roller moves back and forth, which would cause the concrete slurry to be lost at the edge of the road and result in a thinner road edge.

[0044] (3) When the extrusion plate on the right side of the present invention descends, as shown in the figure, it will drive the push rod two to descend, and the push rod two will drive the step block and the sliding rod to descend. When the step block descends, the high step of the step block will contact the concrete. When the high step of the step block applies pressure to the concrete surface, it will first squeeze out some air bubbles from the concrete surface. There is a height difference between the low step and the high step, so the air bubbles will migrate to the surface, thereby reducing the number of small air bubbles remaining on the concrete surface. This effectively prevents the uneven contact between the vibrating roller and the concrete surface when the vibrating roller vibrates the concrete surface, which may cause small air bubbles to remain on the concrete surface after vibration. If the flat roller is directly pressed, the air bubbles will break on the concrete surface, forming small depressions and causing the road surface to form a honeycomb surface.

[0045] (4) When the vibrating frame vibrates, the transmission plate will vibrate. When the transmission plate vibrates, it will contact the whole plate and transmit the vibration to the whole plate, causing the whole plate to vibrate. When the whole plate vibrates upward, it will drive the second spring return rod to rise, causing the second spring return rod to be squeezed and accumulate rebound force. Then, through the rebound force of the second spring return rod, the whole plate will return to its position. At the same time, when the support frame moves, it will drive the whole plate to move. The whole plate will slide on the concrete surface while vibrating. Vibration makes the concrete surface mortar more fluid. When the whole plate moves, it can quickly scrape the concrete surface and form transverse anti-slip stripes, effectively preventing the flattening roller from moving back and forth and pushing the concrete to flow, which can easily cause wavy patterns on the concrete surface.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Example 1, please refer to Figures 1-7 The present invention is a road and bridge construction leveling device, including a support frame 111, a wheel frame 112 fixedly connected to the left and right sides of the support frame 111, and a drive motor 113 fixedly connected to the top of the support frame 111.

[0062] A frame mechanism 1 is provided, with a translation component 11 fixedly installed on the side wall of the frame mechanism 1 and a smoothing component 12 rotatably installed on the inner wall of the frame mechanism 1. The smoothing component 12 is used to smooth the road surface.

[0063] Leveling mechanism 2, installed at the bottom of frame mechanism 1, is used to fill depressions in the road surface; and

[0064] Flattening mechanism 3, located at the bottom of frame mechanism 1, is used to press the road edge;

[0065] The bottom of the support frame 111 is provided with a vibrating frame 211, and the top of the vibrating frame 211 is fixedly connected with eight spring rods 213. The outer walls of the eight spring rods 213 are slidably connected to the inner wall of the support frame 111, and the outer walls of the support frame 111 are fixedly connected with eight limiting frames 212.

[0066] When the road needs to be smoothed, the smoothing component 12 is moved on the road by the translation component 11, and then the road surface is smoothed by the smoothing component 12. After that, the concrete flow range is increased by the leveling mechanism 2, which allows the surrounding concrete to migrate more fully to the depression and fill the depression on the road surface. Finally, the concrete at both ends of the road is compacted by the flattening mechanism 3.

[0067] Framework 1 includes:

[0068] Translation component 11 is fixedly installed on the side wall of the translation component 111 and on the side wall of the support frame 111, and is used to drive the frame mechanism 1 to move.

[0069] Smoothing component 12 is rotatably mounted on the inner wall of support frame 111 via a rotating component, and is used to smooth the road surface;

[0070] The rotating component includes a bidirectional spiral auger 121 rotatably connected to the inner wall of the support frame 111, and a toothed chain assembly 123 is fixedly connected to the outer wall of the bidirectional spiral auger 121.

[0071] When smoothing the road, the smoothing component 12 is moved on the road surface by the translation component 11, and then the road surface is smoothed by the smoothing component 12.

[0072] Leveling mechanism 2 includes:

[0073] Vibration assembly 21 is slidably disposed on the inner wall of support frame 111 for vibrating deep concrete.

[0074] The reciprocating component 22 is fixedly installed on the side wall of the support frame 111 by fasteners to increase the flow range of concrete.

[0075] The fasteners include a second concave-convex ring 222 fixedly connected to the left side of the support frame 111, and a first concave-convex ring 221 fixedly connected to the right side of the support frame 111.

[0076] When the smoothing component 12 smooths the road surface, it drives the vibrating component 21 to vibrate and compact the concrete deep inside, reducing the depressions on the concrete surface. Then, the reciprocating component 22 pushes the concrete to flow, expanding the flow range of the concrete, allowing the surrounding concrete to migrate more fully to the depressions, effectively preventing depressions from remaining after the concrete surface is smoothed, which would affect the smoothness of the road surface.

[0077] Flattening mechanism 3 includes:

[0078] The extrusion assembly 31 is slidably mounted on the inner wall of the support frame 111 via a sliding member, and is used to extrude concrete at both ends of the road.

[0079] The sliding component includes two extrusion plates 313 that are slidably connected to the inner wall of the support frame 111, and the top of each of the two extrusion plates 313 is rotatably connected to a connecting rod 314.

[0080] Push component 32 is slidably disposed on the inner wall of support frame 111 via support member, and is used to squeeze air bubbles on concrete surface;

[0081] The support includes seven sliding rods 322 that are slidably connected to the inner wall of the support frame 111, and a step block 321 is provided at the bottom of the support frame 111;

[0082] When the reciprocating component 22 moves back and forth, it causes the extrusion component 31 to descend, extruding both ends of the road and inhibiting the loss of grout. This effectively prevents the concrete slurry from flowing to the edge when the reciprocating component 22 moves back and forth, thus preventing the loss of concrete slurry at the edge of the road. The extrusion component 31 will drive the pushing component 32 to descend, expelling residual air bubbles on the concrete surface. This effectively prevents the surface of the concrete from being compacted by the smoothing component 12, which may leave tiny air bubbles on the surface after compaction. Direct compaction will cause the air bubbles to burst on the concrete surface, forming small depressions.

[0083] Example 2, please refer to Figures 1-11 The present invention is a leveling device for road and bridge construction. Based on Example 1, the translation component 11 includes a pulley group 114 set on the top of the support frame 111. The output end of the drive motor 113 is fixedly connected to the side wall of the pulley group 114. A fixing block 115 is fixedly connected to the top of the support frame 111. The inner wall of the fixing block 115 is rotatably connected to the outer wall of the pulley group 114.

[0084] The smoothing assembly 12 includes an eccentric rod 125 rotatably connected to the inner wall of the support frame 111, a rotating rod 126 rotatably connected to the inner wall of the support frame 111, and the outer wall of the pulley assembly 114 fixedly connected to the inner wall of the toothed chain assembly 123.

[0085] A second pulley assembly 122 is fixedly connected to the outer wall of the first pulley assembly 114. The inner wall of the second pulley assembly 122 is fixedly connected to the outer wall of the eccentric rod 125. A second toothed chain assembly 124 is fixedly connected to the outer wall of the first pulley assembly 114. The inner wall of the second toothed chain assembly 124 is fixedly connected to the outer wall of the rotating rod 126.

[0086] A vibrating roller 127 is provided at the bottom of the support frame 111. The inner wall of the vibrating roller 127 is rotatably connected to the outer wall of the eccentric rod 125. A flattening roller 128 is provided at the bottom of the support frame 111. Two sliding rods are fixedly connected to the outer wall of the rotating rod 126. The outer walls of the two sliding rods are slidably connected to the inner wall of the flattening roller 128.

[0087] When road surface smoothing is required, the power motor on the wheel frame 112 is activated, such as... Figure 2 As shown in the state of G, it drives the pulley to rotate, as... Figure 2 As shown in the state of H, the wheel rotates through gear and chain transmission, as... Figure 2 As shown in state I, the rotation of the wheels drives the support frame 111 to move on the road. Then, the drive motor 113 is started, driving the pulley set 114 to rotate. The pulley set 114 then drives the pulley set 122, the toothed chain set 123, and the toothed chain set 124 to rotate, causing the bidirectional spiral auger 121, the eccentric rod 125, and the rotating rod 126 to rotate respectively. Since the eccentric part of the eccentric rod 125 is in contact with the vibrating roller 127, a periodic unbalanced force is generated when the eccentric rod 125 rotates. This unbalanced force is transmitted to the vibrating roller 127, driving the vibrating roller 126 to rotate. The 27 reciprocates, causing the vibrating roller 127 to vibrate. Simultaneously, as the rotating rod 126 rotates, the sliding rod drives the flattening roller 128 to rotate. When the bidirectional spiral auger 121 rotates, the rotating blades push the concrete accumulated on the road laterally to both sides, spreading the concrete evenly along the width of the road. As the support frame 111 moves along the road, the vibrating roller 127 comes into contact with the concrete. The vibration of the vibrating roller 127 compacts the concrete surface, making the concrete dense and removing some air bubbles. Then, the flattening roller 128 comes into contact with the concrete, compacting and leveling the concrete surface.

[0088] The vibrating assembly 21 includes a second spring rod 214 that is slidably connected to the inner wall of the limiting frame 212, and the outer walls of the eight first spring rods 213 are all slidably connected to the inner walls of the eight limiting frames 212.

[0089] When the vibrating roller 127 swings, it comes into contact with the tamping frame 211. During the swinging process, the vibrating roller 127 pushes the tamping frame 211 upward, which in turn drives the spring rod 213 upward, allowing the spring rod 213 to accumulate rebound force. When the vibrating roller 127 separates from the tamping frame 211, the rebound force of the spring rod 213 is released, causing the tamping frame 211 to return to its original position. For example, when the vibrating roller 127 pushes the tamping frame 211 to move to the left: Figure 7 As shown, the spring rod 213 will compress the spring rod 214, allowing the spring rod 214 to accumulate rebound force, thereby causing the vibrator 211 to swing back and forth, making the vibrator 211 vibrate. Since the vibrator 211 is inserted into the concrete, it will vibrate the concrete to a deeper level, making the vibration more uniform.

[0090] The reciprocating assembly 22 includes a second connecting rod 224 fixedly connected to the left side of the flattening roller 128, and a first connecting rod 223 fixedly connected to the right side of the flattening roller 128;

[0091] When the flattening roller 128 rotates, it causes the connecting rod 224 to separate from the protruding position of the concave-convex ring 222. At this time, the connecting rod 223 is not in contact with the concave-convex ring 221. As the flattening roller 128 continues to rotate, the connecting rod 223 will come into contact with the protruding position of the concave-convex ring 221 and be squeezed, pushing the flattening roller 128 towards the concave-convex ring 222, causing the flattening roller 128 to move laterally. Because the connecting rod 224 will separate from the protruding position of the concave-convex ring 222, the flattening roller 128 can move smoothly. When the connecting rod 223 separates from the protruding position of the concave-convex ring 221... After separation, connecting rod 224 will also contact the protruding position of the concave-convex ring 222, pushing the flattening roller 128 to move towards the concave-convex ring 221. This process is repeated, allowing the flattening roller 128 to move laterally back and forth. The flattening roller 128 will then push the concrete to flow, increasing the flow range of the concrete. By vibrating the concrete to its depths, the vibration is made more uniform, reducing depressions on the concrete surface. In conjunction with the lateral movement of the flattening roller 128, the flow range of the concrete is increased, allowing the surrounding concrete to migrate more fully to the depressions, achieving dynamic filling. This effectively prevents depressions from remaining after the concrete surface is smoothed, thus affecting the smoothness of the road surface.

[0092] The extrusion assembly 31 includes two annular grooves 311 formed on the inner wall of the flattening roller 128. A push rod 312 is rotatably connected to the inner wall of each of the two annular grooves 311. The outer wall of each of the two push rods 312 is slidably connected to the inner wall of the support frame 111. The side wall of each of the two push rods 312 is rotatably connected to the inner wall of each of the two connecting rods 314.

[0093] The bottom of the support frame 111 is provided with two pressure plates 315. The top of each of the two pressure plates 315 is fixedly connected with two spring return rods 316. The four spring return rods 316 are in pairs. The outer walls of the two sets of spring return rods 316 are slidably connected to the inner walls of the two extrusion plates 313.

[0094] When the flattening roller 128 moves towards the concave-convex ring 222, it drives the push rod 312 to move, causing the push rod 312 on the right side to push the connecting rod 314 to rotate. Figure 9As shown, the connecting rod 314 pushes the extrusion plate 313 down, causing the spring return rod 316 and the pressing plate 315 to descend, allowing the pressing plate 315 to contact the concrete at one end of the road and extrude the concrete. The extrusion plate 313 then presses the spring return rod 316, increasing the extrusion force of the pressing plate 315 on the concrete. At the same time, the push rod 312 on the left side drives the extrusion plate 313 and the pressing plate 315 to rise, separating the pressing plate 315 on the left side from the concrete at the other end of the road. This continues until the pressing roller 128 moves towards the concave-convex ring 221. The push rod 312 on the left side moves, pushing the extrusion plate 313 and the pressing plate 315 down to extrude the concrete. As the pressing roller 128 pushes the concrete towards the edge of the road, the pressing plate 315 descends to extrude the concrete, suppressing the loss of slurry at the edge. This effectively prevents the concrete slurry from flowing towards the edge when the pressing roller 128 moves back and forth, which would cause the concrete slurry to be lost at the road edge, resulting in a thinner road edge.

[0095] The pushing assembly 32 includes a second pushing rod 323 fixedly connected to the side wall of the left extrusion plate 313, the top of the step block 321 is fixedly connected to the bottom of the seven sliding rods 322, and the top of the step block 321 is fixedly connected to the bottom of the second pushing rod 323.

[0096] The bottom of the support frame 111 is provided with a flat plate 324, and the top of the flat plate 324 is fixedly connected with eight spring return rods 325. The outer walls of the eight spring return rods 325 are slidably connected to the inner wall of the support frame 111. The side wall of the vibrating frame 211 is fixedly connected with eight transmission plates 326.

[0097] Among them, when the extrusion plate 313 located on the right side descends, such as Figure 9 As shown, the push rod 323 will descend, causing the step block 321 and sliding rod 322 to descend. When the step block 321 descends, the higher step of the step block 321 will contact the concrete. When the higher step of the step block 321 applies pressure to the concrete surface, some air bubbles will be squeezed out from the concrete surface. There is a height difference between the lower and higher steps, so the air bubbles will migrate towards the surface. This avoids applying pressure all at once and presses the air bubbles into the concrete, thereby reducing the number of tiny air bubbles remaining on the concrete surface. This effectively prevents the uneven contact between the vibrating roller 127 and the concrete surface when the vibrating roller 127 vibrates the surface concrete, which may result in tiny air bubbles remaining on the concrete surface after vibration. If the flattening roller 128 directly rolls over the concrete, the air bubbles will break on the concrete surface, forming small depressions and causing a honeycomb surface on the road surface.

[0098] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding connection positions.

[0099] One specific application of this embodiment is as follows: When using this invention, the device is moved to a road construction location. When road leveling is required, the power motor on the wheel frame 112 is activated, such as... Figure 2 As shown in the state of G, it drives the pulley to rotate, as... Figure 2 As shown in the state of H, the wheel rotates through gear and chain transmission, as... Figure 2 As shown in state I, the rotation of the wheels drives the support frame 111 to move on the road. Then, the drive motor 113 is started, driving the pulley set 114 to rotate. The pulley set 114 then drives the pulley set 122, the toothed chain set 123, and the toothed chain set 124 to rotate, causing the bidirectional spiral auger 121, the eccentric rod 125, and the rotating rod 126 to rotate respectively. Since the eccentric part of the eccentric rod 125 is in contact with the vibrating roller 127, a periodic unbalanced force is generated when the eccentric rod 125 rotates. This unbalanced force is transmitted to the vibrating roller 127, driving the vibrating roller 126 to rotate. 27 reciprocates, causing the vibrating roller 127 to vibrate. At the same time, when the rotating rod 126 rotates, the sliding rod will drive the flattening roller 128 to rotate. When the bidirectional spiral auger 121 rotates, the rotating blades push the concrete piled on the road laterally to both sides, spreading the concrete evenly along the width of the road. When the support frame 111 moves along the road, the vibrating roller 127 will come into contact with the concrete. The vibration of the vibrating roller 127 will compact the concrete surface, making the concrete dense and removing some air bubbles. Then the flattening roller 128 will come into contact with the concrete, compacting and leveling the concrete surface.

[0100] When the vibrating roller 127 swings, it comes into contact with the tamping frame 211. During the swinging process, the vibrating roller 127 pushes the tamping frame 211 upward, which in turn drives the spring rod 213 upward, allowing the spring rod 213 to accumulate rebound force. When the vibrating roller 127 separates from the tamping frame 211, the rebound force of the spring rod 213 is released, causing the tamping frame 211 to return to its original position. For example, when the vibrating roller 127 pushes the tamping frame 211 to move to the left: Figure 7 As shown, the spring rod 213 will compress the spring rod 214, allowing the spring rod 214 to accumulate rebound force, thereby causing the vibrator 211 to swing back and forth, making the vibrator 211 vibrate. Since the vibrator 211 is inserted into the concrete, it will vibrate the deep part of the concrete, making the vibration more uniform.

[0101] Simultaneously, as the flattening roller 128 rotates, it causes the connecting rod 224 to separate from the protruding position of the concave-convex ring 222. At this time, the connecting rod 223 is not in contact with the concave-convex ring 221. As the flattening roller 128 continues to rotate, the connecting rod 223 will come into contact with the protruding position of the concave-convex ring 221 and be squeezed, pushing the flattening roller 128 towards the concave-convex ring 222, causing the flattening roller 128 to move laterally. Because the connecting rod 224 will separate from the protruding position of the concave-convex ring 222, the flattening roller 128 can move smoothly. When the connecting rod 223 separates from the protruding position of the concave-convex ring 221... After separation, connecting rod 224 will also contact the protruding position of the concave-convex ring 222, pushing the flattening roller 128 to move towards the concave-convex ring 221. This process is repeated, allowing the flattening roller 128 to move laterally back and forth. The flattening roller 128 will then push the concrete to flow, increasing the flow range of the concrete. By vibrating the concrete to its depths, the vibration is made more uniform, reducing depressions on the concrete surface. In conjunction with the lateral movement of the flattening roller 128, the flow range of the concrete is increased, allowing the surrounding concrete to migrate more fully to the depressions, achieving dynamic filling. This effectively prevents depressions from remaining after the concrete surface is smoothed, thus affecting the smoothness of the road surface.

[0102] Secondly, when the flattening roller 128 moves towards the concave-convex ring 222, it will drive the push rod 312 to move, causing the push rod 312 on the right side to push the connecting rod 314 to rotate, such as Figure 9 As shown, the connecting rod 314 pushes the extrusion plate 313 down, causing the spring return rod 316 and the pressing plate 315 to descend, allowing the pressing plate 315 to contact the concrete at one end of the road and extrude the concrete. The extrusion plate 313 then presses the spring return rod 316, increasing the extrusion force of the pressing plate 315 on the concrete. At the same time, the push rod 312 on the left side drives the extrusion plate 313 and the pressing plate 315 to rise, allowing the pressing plate 315 on the left side to separate from the concrete at the other end of the road. This continues until the pressing roller 128 moves towards the concave-convex ring 221. The push rod 312 on the left side moves, pushing the extrusion plate 313 and the pressing plate 315 down to extrude the concrete. As the pressing roller 128 pushes the concrete towards the edge of the road, the pressing plate 315 descends to extrude the concrete, suppressing the loss of slurry at the edge. This effectively prevents the concrete slurry from flowing towards the edge when the pressing roller 128 moves back and forth, which would cause the concrete slurry to be lost at the edge of the road, resulting in a thinner road edge.

[0103] Secondly, as the extrusion plate 313 on the right side descends, as... Figure 9As shown, the push rod 323 will descend, causing the step block 321 and sliding rod 322 to descend. When the step block 321 descends, the higher step of the step block 321 will contact the concrete. When the higher step of the step block 321 applies pressure to the concrete surface, some air bubbles will be squeezed out from the concrete surface. Since there is a height difference between the lower and higher steps, the air bubbles will migrate towards the surface, avoiding one-time pressure application and pressing the air bubbles into the concrete. This reduces the number of tiny air bubbles remaining on the concrete surface and effectively prevents the uneven contact between the vibrating roller 127 and the concrete surface when the vibrating roller 127 vibrates the surface concrete. This would cause tiny air bubbles to remain on the concrete surface after vibration, and if the flattening roller 128 directly rolls over them, the air bubbles will break on the concrete surface, forming small depressions and causing a honeycomb surface on the road surface.

[0104] Secondly, when the vibrating frame 211 vibrates, the transmission plate 326 vibrates. When the transmission plate 326 vibrates, it comes into contact with the flat plate 324, transmitting the vibration to the flat plate 324, causing the flat plate 324 to vibrate. When the flat plate 324 vibrates upward, it drives the spring return rod 325 to rise, causing the spring return rod 325 to be compressed and accumulate rebound force. Then, through the rebound force of the spring return rod 325, the flat plate 324 returns to its original position. At the same time, when the support frame 111 moves, it drives the flat plate 324 to move. The flat plate 324 will slide on the concrete surface during vibration. Vibration makes the surface mortar of the concrete more fluid. When the flat plate 324 moves, it can quickly scrape the concrete surface, forming transverse anti-slip stripes, effectively preventing the flattening roller 128 from moving back and forth and pushing the concrete to flow, which can easily cause wavy patterns on the concrete surface.
