Description

Technical Field

[0001] This invention relates to the field of road construction technology, specifically to an intelligent road construction and paving equipment and method. Background Technology

[0002] The paving equipment used for road construction mainly consists of an engine, a traveling mechanism, a material supply system, a screed device, and a control system. By controlling the overall movement, the concrete mixture is supplied in an orderly manner and then shaped and paved by the screed device. The screed device has a vibrating beam and a vibrator, which can also vibrate and compact the concrete mixture to avoid the presence of air inside due to direct shaping. Furthermore, intelligent road paving construction is achieved through laser positioning combined with hydraulic dynamic adjustment.

[0003] However, during road construction and paving, the mixture needs to be guided to the paving position. The spiral guide is a circular guide, and when the paving width is large, the spiral guide is prone to differences in the amount of mixture at the paving position. This can easily lead to different densities at different positions during paving, affecting the stability of the road paving. Furthermore, when paving at road curves, the screed on the screed device is a flat structure for shaping and leveling, and it operates at a certain working angle. Because the curve position is curved, the flat screed will interfere with the already leveled position after the curved movement, which can easily lead to irregular paving edges at the curve position. Summary of the Invention

[0004] This invention provides an intelligent road construction and paving equipment and method that overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An intelligent road construction paving equipment includes a paving mechanism, a diversion cylinder, a transmission device, a cab, a track device, and a machine body. The cab electrically drives the track device at the lower end of the machine body. The paving mechanism is fixed to the side of the machine body, and the lowest point of the paving mechanism is slightly higher than the lowest point of the track device. The transmission device is inclined and fixed to the side of the diversion cylinder, and the transmission device is equipped with a transmission belt. The transmission belt is driven to transport concrete into the diversion cylinder and to form and pave the concrete within the paving mechanism.

[0007] The paving mechanism includes a shell, a guiding mechanism, a forming mechanism, a power box, a vibrating rod, a base, and a guide platform. The vibrating rod is electrically connected to the cab via the power box on the surface of the shell. The guiding mechanism is elastically fixed to the bottom of the shell via the base. The outlet end of the guide platform, fixed to the upper end of the shell, corresponds to the surface of the guiding mechanism. The lower side of the forming mechanism is a concave hollow structure. The guiding mechanism guides the concrete in a fan shape to the position below the vibrating rod. The concrete vibrated by the vibrating rod is formed and laid at the concave hollow structure position of the forming mechanism.

[0008] A preferred technical solution: The guiding mechanism is provided with a guide plate, a circular plate and a shell plate. The guide plate is arranged in a fan-shaped inclination on the outside of the circular plate, and the shell plate guides the concrete along the two sides of the circular plate and the guide plate. The middle surface of the circular plate is provided with a raised "V" shaped structure, which guides the concrete evenly towards the fan-shaped guide plate. The circular plate is located below the outlet end of the guide platform, and the circular plate is fixed to the inside of the shell by the shell plate.

[0009] A preferred technical solution: The guide plate is provided with a movable block, a guide plate, a swing structure and a triangular plate. The swing structure is connected to the middle of the guide plate through the movable block. The guide plate is inclinedly arranged on the side of the triangular plate and is inclinedly fixed to the side of the circular plate through the triangular plate.

[0010] A preferred technical solution: The swing structure is provided with a connecting strip and a triangular block. The triangular blocks are arranged at equal intervals on the left and right sides of the connecting strip. There is a gap between the triangular block and the guide plate. Concrete is discharged in the gap. When the height of the concrete reaches the triangular block, the triangular block guides the concrete to move towards the triangular plate.

[0011] A preferred technical solution: The forming mechanism includes a rubber strip, a limiting plate, an arc plate, an extrusion structure, and a first spring. The extrusion structure is symmetrically arranged inside the limiting plate. The first spring is fixed to the lower end of the limiting plate by a support strip. The rubber strips at both ends of the arc plate are connected to the inner ends of the first spring. The arc plate is pressed against the extrusion structure below. The arc plate and the extrusion structure form a concave structure, and the concave structure opens downward to form concrete.

[0012] A preferred technical solution: The extrusion structure includes a second spring, a roller, a support rod, a rubber block, a screw, and a fixing tube. The fixing tube is fixed to the lower end of the limiting plate, and a hole is provided on the outer side of the limiting plate corresponding to the screw position. The screw spirally pushes the rubber block on the left side of the fixing tube. The two ends of the second spring are connected to support rods, and the two support rods are at a 130° angle. The second spring is located inside the rubber block and is elastically bent. The roller at the outer end of the support rod is elastically guided on the side of the concrete.

[0013] A method for intelligent road surface paving equipment, based on the aforementioned intelligent road surface paving equipment, includes the following specific steps:

[0014] S1: Concrete is transported to the inside of the diversion cylinder via the conveyor belt on the conveyor device. At the same time, the cab drives the track device to move in an arc. The concrete through the diversion cylinder falls onto the surface of the guide plate at the outlet end of the guide platform. Thus, the concrete is guided towards the inclined guide plate surface by the obstruction of the outer shell plate. Then, the concrete falls evenly from the guide plate to the lower end of the vibrator and is vibrated by the vibrator. As the track device moves, the concrete is shaped and spread towards the forming mechanism.

[0015] S2: When concrete slides off the guide plate, it slides off the surface of the guide plate and the triangular plate. When the height of the concrete on the guide plate exceeds the gap below the swing structure, it is dispersed to the triangular plates on both sides under the guidance of the triangular blocks in the swing structure.

[0016] S3: When the triangular block guides the concrete, the elasticity of the movable block causes the connecting strip to swing the triangular block according to the amount of concrete. As a result, the concrete is tilted and guided on the triangular block to the triangular plates on both sides, so that the two adjacent triangular plates divert the concrete to the guide plate in the middle.

[0017] S4: When the tracked device moves in an arc, the concrete is shaped by the concave structure formed by the arc plate at the lower end of the limiting plate and the extrusion structure. During the shaping process, the arc plate uses the elasticity of the first spring through the rubber strip to press the concrete surface in an arc. The concrete surface and the two side edges are flattened at right angles by the arc plate and the upper end of the extrusion structure. When the limiting plate moves in an arc, the concrete rolls on both sides through the rollers in the extrusion structure. The two support rods swing according to the arc of the concrete on the rollers. During the swing, the support rods are elastically bent through the second spring and the rubber block, so that the two rollers exert the same pressure on the sides of the arc-shaped concrete.

[0018] Compared with existing technologies, this technical solution has the following advantages:

[0019] In this invention, concrete flows in a fan shape from the inclined guiding mechanism surface to the guide plate. A portion of the concrete flows from the guide plate surface. Concrete exceeding the height of the gap above the guide plate is guided to both sides by the swinging structure. Subsequently, the triangular blocks within the swinging structure guide the concrete to the left and right sides, and in conjunction with the left and right swinging of the movable blocks, when there is too much concrete on the guide plate surface, it is guided to the triangular plates. The concrete slides from the triangular plates to the adjacent swinging structure surface. Through the mutual guidance of the fan-shaped guide plates and triangular plates, the concrete slides evenly to the forming position, achieving the same amount of concrete at each position, and thus the same density of concrete at each position.

[0020] In this invention, after the concrete vibrates at the lower end of the vibrator, the limiting plate moves in an arc shape following the track device. During the process of the arc plate and the two extrusion structures forming the concrete pavement, the arc plate can also elastically scrape the upper surface of the concrete. Then, the arc plate and the extrusion structure guide the concrete to form at a right angle at the upper corner of the concrete. When the extrusion structure guides the concrete to form in an arc shape on both sides, the rollers at the outer ends of the two support rods abut against the side of the concrete and the included angle is elastically expanded by the second spring. The second spring swings through the rubber block, so that the two rollers always maintain a certain pressure on the side of the concrete according to the arc angle, thereby keeping the side of the concrete in an arc shape under a certain pressure and avoiding irregular arc paving.

Detailed Implementation

[0030] like Figures 1 to 7 As shown, the present invention proposes an intelligent road construction paving equipment, including a paving mechanism 1, a diversion cylinder 2, a transmission device 3, a cab 4, a track device 5, and a machine body 6. The cab 4 electrically drives the track device 5 at the lower end of the machine body 6. The paving mechanism 1 is fixed to the side of the machine body 6, and the lowest end of the paving mechanism 1 is slightly higher than the lowest end of the track device 5. The transmission device 3 is inclined and fixed to the side of the diversion cylinder 2, and the transmission device 3 is equipped with a transmission belt. The transmission belt is driven to transport concrete into the diversion cylinder 2, and the concrete is formed and paved in the paving mechanism 1.

[0031] The paving mechanism 1 includes a housing 11, a guiding mechanism 12, a forming mechanism 13, a power box 14, a vibrating rod 15, a base 16, and a flow guide 17. The vibrating rod 15 is electrically connected to the cab 4 via the power box 14 on the surface of the housing 11. The guiding mechanism 12 is elastically fixed to the bottom of the housing 11 via the base 16. The outlet end of the flow guide 17, which is fixed to the upper end of the housing 11, corresponds to the surface of the guiding mechanism 12. The lower side of the forming mechanism 13 is a concave hollow structure. The guiding mechanism 12 guides the concrete in a fan shape to the position below the vibrating rod 15. The concrete vibrated by the vibrating rod 15 is formed and laid at the concave hollow structure position of the forming mechanism 13.

[0032] Furthermore, the concrete falls from the inclined part of the guide mechanism 12 to the lower end of the vibrator 15, and the height of the concrete is higher than the lowest point of the vibrator 15, so that the air inside the concrete can be discharged when the vibrator 15 vibrates. Thus, when the housing 11 moves along the ground, the concrete at the lower end of the vibrator 15 is covered and shaped by the forming mechanism 13.

[0033] Furthermore, when the driver's cab 4 drives the track device 5, it can intelligently control the movement by setting a certain arc angle, without the need for manual control, so that the track device 5 moves at an angle close to an arc.

[0034] The guiding mechanism 12 includes a guide plate 121, a circular plate 122, and a housing plate 123. The guide plate 121 is arranged in a fan-shaped inclination outside the circular plate 122, and the housing plate 123 guides the concrete along the two sides of the circular plate 122 and the guide plate 121. The middle surface of the circular plate 122 has a raised "V" shaped structure, which guides the concrete evenly towards the fan-shaped guide plate 121. The circular plate 122 corresponds to the lower part of the outlet end of the guide platform 17, and the circular plate 122 is fixed to the inside of the housing 11 by the housing plate 123.

[0035] Furthermore, the outer shell plate 123 is connected to the left and right sides of the guide plate 121 at its edge to prevent concrete from falling from the guide plate 121 to the left and right sides. The outer shell plate 123 of the circular plate 122 is open, allowing the concrete to move towards the circular plate 122 and preventing concrete from splashing to the outside. The circular plate 122 has a "V" shaped structure in the middle, with the two ends of the "V" shaped structure extending to the left and right sides of the guide plate 121. This allows the concrete to flow through the middle of the circular plate 122 above the two sides of the "V" shaped structure. The concrete is then guided from the two sides of the "V" shaped structure and flows in an arc shape from the circular plate 122 towards the entrance end of the guide plate 121. This prevents the concrete from accumulating and becoming chaotic at the entrance end of the guide plate 121, and prevents the concrete from being too piled up and causing the middle of the guide plate 121 to slip first, resulting in uneven flow.

[0036] The guide plate 121 is provided with a movable block 211, a guide plate 212, a swing structure 213 and a triangular plate 214. The swing structure 213 is connected to the middle of the guide plate 212 through the movable block 211. The guide plate 212 is inclinedly arranged on the side of the triangular plate 214 and is inclinedly fixed to the side of the circular plate 122 through the triangular plate 214.

[0037] Furthermore, the movable block 211 is made of rubber, and the swing structure 213 swings left and right through the movable block 211, causing the swing structure 213 to swing towards the side with more concrete, thereby reducing the flow on the side with more concrete.

[0038] The swing structure 213 is provided with a connecting strip 31 and a triangular block 32. The triangular block 32 is arranged equidistantly on the left and right sides of the connecting strip 31. There is a gap between the triangular block 32 and the guide plate 212. Concrete is discharged in the gap. When the height of the concrete reaches the triangular block 32, the triangular block 32 guides the concrete to move towards the triangular plate 214.

[0039] Furthermore, the outermost ends of the arranged triangular blocks 32 are in a diagonal state, and the concrete is guided to both sides through the diagonal state of the triangular blocks 32. The concrete flow height exceeds the gap below the swing structure 213 and then acts on the triangular blocks 32.

[0040] In this invention, concrete flows in a fan shape from the inclined guiding mechanism 12 to the guide plate 121. A portion of the concrete flows from the surface of the guide plate 212. Concrete exceeding the height of the gap above the guide plate 212 is guided to both sides by the swinging structure 213. The triangular blocks 32 within the swinging structure 213 then guide the concrete to the left and right, coordinating with the left-right swinging of the movable block 211. This causes excessive concrete on the surface of the guide plate 212 to be guided towards the triangular plate 214, which then slides onto the adjacent swinging structure 213 surface. The fan-shaped arrangement of the guide plates 212 and triangular plates 214 guides the concrete, ensuring it slides evenly to the forming position, achieving the same amount of concrete at each location, and consequently, the same density of concrete at each location.

[0041] The forming mechanism 13 includes a rubber strip 311, a limiting plate 312, an arc plate 313, an extrusion structure 314, and a first spring 315. The extrusion structure 314 is symmetrically arranged inside the limiting plate 312. The first spring 315 is fixed to the lower end of the limiting plate 312 by a support strip 316. The rubber strips 311 at both ends of the arc plate 313 are connected to the inner ends of the first spring 315. The arc plate 313 is pressed against the extrusion structure 314 below. The arc plate 313 and the extrusion structure 314 form a concave structure, and the concave structure opens downward to form concrete.

[0042] Furthermore, the curved plate 313 is made of plastic, which has a certain degree of elasticity and toughness and can be bent to a certain extent. The curved plate 313 abuts against the upper end of the extrusion structure 314, so that the concrete surface is blocked and scraped by the curved plate 313 while the corner of the concrete is flattened.

[0043] The extrusion structure 314 includes a second spring 41, a roller 42, a support rod 43, a rubber block 44, a screw 45, and a fixing tube 46. The fixing tube 46 is fixed to the lower end of the limiting plate 312, and the outer side of the limiting plate 312 has a hole corresponding to the position of the screw 45. The screw 45 spirally pushes the rubber block 44 on the left side of the fixing tube 46. The second spring 41 is connected to the support rod 43 at both ends, and the two support rods 43 form a 130° angle. The second spring 41 is located inside the rubber block 44 and is elastically bent. The roller 42 at the outer end of the support rod 43 is elastically guided on the side of the concrete.

[0044] Furthermore, the lower end of the arc plate 313 abuts against the upper ends of the two support rods 43. When the limiting plate 312 moves in an arc shape, the side of the concrete squeezes one of the rollers 42 and swings through the support rod 43 at one end of the second spring 41, causing the roller 42 connected to the support rod 43 at the other end of the second spring 41 to abut against the side of the concrete. Thus, the side of the concrete achieves the same pressure under the swing of the two rollers 42 through the second spring 41.

[0045] Furthermore, when the screwdriver is inserted through the hole on the outside of the limiting plate 312 to rotate the screw 45, the support position of the screw 45 on the rubber block 44 is adjusted, and the pressure of the roller 42 on the side of the concrete is adjusted according to the curvature of the arc.

[0046] It is necessary to explain that the reason for not directly using the arc-shaped extrusion structure 314 is that the track device 5 can only move in an arc-shaped state, which would easily cause the arc-shaped extrusion structure 314 to be wavy and uneven on the side of the concrete. Instead, the two swinging support rods 43 are used to guide the side of the concrete by the second spring 41, so as to achieve the effect of uniformly scraping the side of the concrete.

[0047] In this invention, after the concrete vibrates at the lower end of the vibrator 15, the limiting plate 312 moves in an arc shape following the track device 5. Thus, during the process of the arc plate 313 and the two extrusion structures 314 forming the concrete pavement, the arc plate 313 can also elastically scrape the upper surface of the concrete. Then, the arc plate 313 and the extrusion structure 314 guide the concrete to form at a right angle at the upper corner of the concrete. When the extrusion structure 314 guides the concrete to form in an arc shape on both sides, the rollers 42 at the outer ends of the two support rods 43 abut against the side of the concrete and the included angle is elastically expanded by the second spring 41. The second spring 41 swings through the rubber block 44, so that the two rollers 42 always maintain a certain pressure on the side of the concrete according to the arc angle, thereby keeping the side of the concrete in an arc shape under a certain pressure and avoiding irregular arc paving.

[0048] A method for intelligent road surface paving equipment, based on the aforementioned intelligent road surface paving equipment, includes the following specific steps:

[0049] S1: Concrete is transported to the inside of the diversion cylinder 2 via the conveyor belt on the conveyor device 3. At the same time, the cab 4 drives the track device 5 to move in an arc. The concrete through the diversion cylinder 2 falls onto the surface of the guide plate 121 at the outlet end of the guide platform 17. Thus, the concrete is guided towards the inclined guide plate 121 surface under the obstruction of the outer shell plate 123. Then, the concrete falls evenly from the guide plate 121 to the lower end of the vibrator 15 and is vibrated by the vibrator 15. Thus, the concrete is shaped and spread towards the forming mechanism 13 under the movement of the track device 5.

[0050] S2: When the concrete slides off the guide plate 121, it slides off the surfaces of the guide plate 212 and the triangular plate 214. When the height of the concrete on the guide plate 212 exceeds the gap below the swing structure 213, it is dispersed to the triangular plates 214 on both sides under the guidance of the triangular block 32 in the swing structure 213.

[0051] S3: When the triangular block 32 guides the concrete, the elasticity of the movable block 211 causes the connecting strip 31 to swing the triangular block 32 according to the amount of concrete, so that the concrete is tilted and guided on the triangular block 32 to the triangular plates 214 on both sides, so that the two adjacent triangular plates 214 divert the concrete to the guide plate 212 in the middle.

[0052] S4: When the track device 5 moves in an arc, the concrete is formed by the concave structure formed by the arc plate 313 at the lower end of the limiting plate 312 and the extrusion structure 314. During the forming process, the arc plate 313 presses the concrete surface in an arc shape against the elasticity of the first spring 315 through the rubber strip 311. The concrete surface and the two side edges are flattened at right angles by the abutting of the upper end of the arc plate 313 and the extrusion structure 314. When the limiting plate 312 moves in an arc, the two sides of the concrete roll through the rollers 42 in the extrusion structure 314. The two support rods 43 swing according to the arc of the concrete on the rollers 42. When swinging, the support rods 43 are elastically bent through the second spring 41 and the rubber block 44, so that the two rollers 42 have the same pressure on the sides of the concrete in the arc state.

[0053] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
