Description

Technical Field

[0001] This invention belongs to the technical field of asphalt concrete pavement rollers, specifically relating to a special roller for colored asphalt concrete pavement based on a vibration mixing pavement system. Background Technology

[0002] In vibratory mixing for long-life pavement systems, vibration mixing solves the problem of uniform mixing of the mixture, and long-life pavement structures solve the pavement structure problem. However, conventional rollers still have some problems in colored asphalt concrete pavement. Currently, dedicated rollers are not used for the construction of colored asphalt concrete pavement; most projects use ordinary vibratory rollers or oscillating rollers. Common vibratory rollers generally use a single vibrating shaft with an eccentric block. The eccentric block generates sinusoidal alternating forces to achieve compaction. The advantages are simple structure and low cost. The disadvantages are that the horizontal component of the force can disrupt the distribution of asphalt slurry in the colored asphalt concrete surface layer, resulting in uneven surface color distribution and an unsightly surface. In addition, the horizontal component of the force can also easily cause poor surface smoothness, loose surface, and micro-cracks. Vibratory rollers employ a dual-shaft vibration system with eccentric blocks. The two eccentric blocks rotate in opposite directions, canceling out the vertical force component and generating oscillating waves and torsional forces to achieve compaction. Advantages include smooth operation and increased compaction efficiency. Disadvantages include energy loss due to the cancellation mechanism and limited downward force. Furthermore, because colored asphalt is a high-molecular polymer with a high melting point and viscosity, compaction is difficult, and vibratory rollers cannot guarantee the required compaction degree for colored asphalt concrete pavements. Currently, ordinary vibratory rollers have low levels of information technology, requiring significant manpower and resources for testing and data analysis after construction. However, with today's advanced non-destructive testing technology, fully information-based construction is entirely feasible.

[0003] With the widespread application of colored asphalt concrete pavement, the demand for special road rollers for colored asphalt concrete pavement will increase in the future. Therefore, developing special road rollers for colored asphalt concrete pavement can improve the compaction quality of colored asphalt concrete pavement and ensure the color stability of colored asphalt concrete pavement, and has broad market prospects.

[0031] The present invention will now be further described with reference to the accompanying drawings.

[0032] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] 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 a part of the embodiments of the present invention, and not all of them. 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.

[0034] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0035] like Figure 1-9 As shown, a special road roller for colored asphalt concrete pavement based on a vibration mixing pavement system includes a vibration section, an edge finishing section, a compaction degree testing section, a smoothness testing section, and a friction coefficient testing section.

[0036] The vibrating part includes a vibrating wheel 1, and a vibrating shaft 6 is rotatably arranged inside the vibrating wheel 1. An eccentric block 7 is arranged on the vibrating shaft 6. The vibrating part is used to drive the vibrating wheel 1 to rotate, and at the same time drive the eccentric block 7 to rotate on its own axis and revolve around the center, so as to compact the road surface 66.

[0037] The edge repair section includes a left vibrating plate 34 and a right vibrating plate 29. The edge repair section is used to repair the edge of the road surface 66 by adjusting the positions of the left vibrating plate 34 and the right vibrating plate 29 respectively, and by vibrating the left vibrating plate 34 and the right vibrating plate 29.

[0038] The compaction degree detection unit includes a Rayleigh wave excitation device and a detector placement device. The Rayleigh wave excitation device includes a rotatably mounted pull rod 51 and an excitation hammer 54 connected to the pull rod 51 via a pull rope 53. The Rayleigh wave excitation device is used to drive the pull rod 51 to rotate, thereby causing the excitation hammer 54 to move upward and then complete free fall to emit Rayleigh waves. The detector placement device includes a detector 58 connected to a vertical rod 65. The detector placement device is used to drive the vertical rod 65 to move up and down, thereby causing the detector 58 to move and intermittently contact the road surface 66.

[0039] The flatness detection unit includes a three-meter ruler box 68, and a movable feeler gauge 67 is provided inside the three-meter ruler box 68. The flatness detection unit is used to drive the three-meter ruler box 68 to move up and down to make it fit the road surface 66, and to perform flatness detection through the movable feeler gauge 67 inside it.

[0040] The friction coefficient detection unit includes a friction block 91 and a force sensor 92 disposed at the bottom of the friction block 91. The friction coefficient detection unit is used to drive the friction block 91 to move up and down, thereby causing the force sensor 92 on it to contact the road surface 66 to detect the friction coefficient.

[0041] For better results, in one embodiment, the special roller for colored asphalt concrete pavement also includes a power system, which consists of an electric motor, a gearbox, a transfer case, a hydraulic motor, and a hydraulic pump. The power system provides power to the vibration section, the edge finishing section, and the compaction testing section.

[0042] For better results, in one embodiment, the special roller for colored asphalt concrete pavement also includes a walking system, which is driven by gears and achieved by a hydraulic pump driving the gear shaft.

[0043] like Figure 1 As shown, the hydraulic pump drives the drive shaft to rotate, which in turn drives the drive gear 13. Since the drive gear 13 meshes with the outer gear 16, its rotation drives the outer gear 16 to rotate. Since the outer gear 16 meshes with the inner gear 15, its rotation drives the inner gear 15 to rotate, which in turn drives the vibrating wheel 1 to rotate. By adding a switching gear, the outer gear 16 can be rotated in both directions, thus enabling the machine to move forward and backward.

[0044] For better performance, in one embodiment, the vibrating unit further includes a hub 3, a left central shaft 2, and a right central shaft 12. The hub 3 is disposed on both sides inside the vibrating wheel 1. The left central shaft 2 and the right central shaft 12 are rotatably connected to the hubs 3 on both sides, and the ends of the left central shaft 2 and the right central shaft 12 are connected by a coupling 9. A vibrating frame 8 is rotatably connected to the left central shaft 2 and the right central shaft 12, and the vibrating shaft 6 is rotatably connected to the vibrating frame 8. A coupling rod 11 is provided on the right central shaft 12, and there are two vibrating shafts 6. The ends of the coupling rod 11 are rotatably connected to the two vibrating shafts 6 respectively.

[0045] Furthermore, the vibrating wheel 1 is a cylindrical wheel, with hubs 3 located on both sides. The left central shaft 2 and right central shaft 12 are both cantilevered half-shafts connected as a single unit by a coupling 9. The coupling 9 uses a sleeve with a bearing at each end, connecting the half-shafts on both sides to achieve reverse rotation at both ends of a single shaft. The left central shaft 2 and right central shaft 12 are mounted on the hub 3 via bearings. A medium spur gear 4 is mounted on the left central shaft 2, meshing with a starting spur gear 5. The starting spur gear 5 is mounted on the vibrating shaft 6, which is mounted on the vibrating frame 8 via bearings and a bearing bracket. The vibrating frame 8 is mounted on the left central shaft 2 and right central shaft 12 via bearings, and an eccentric block 7 is mounted on the vibrating shaft 6. The coupling rod 11 is mounted on the right central shaft 12, with its two ends connected to the two vibrating shafts 6 via bearings. The driving spur gear 13 is mounted on the right central shaft 12. The driving spur gear 13 meshes with the external spur gear 16, which is mounted on the external spur gear shaft 14. The external spur gear 16 meshes with the internal gear cylinder 15, which is mounted on the vibrating wheel 1.

[0046] The working principle of the vibration system is as follows: This invention adopts a structure of two cantilever shafts and two vibration shafts 6. The two cantilever shafts are connected by a coupling 9, and the two vibration shafts 6 are connected by a coupling rod 11. The two sets of eccentric blocks 7 rotate in the same direction and revolve in opposite directions, so that the excitation force generated by the two sets of eccentric blocks 7 is always superimposed vertically downwards, with no horizontal component. During operation, the two sets of eccentric blocks 7 complete one conversion by rotating and revolving 180 degrees. The excitation force generated by the two sets of eccentric blocks 7 is superimposed vertically downwards once in the horizontal direction and once in the vertical direction, producing a torsional oscillation at other positions, achieving a kneading effect. Figure 2 As shown in (a), the excitation forces generated by the two sets of eccentric blocks 7 in the horizontal direction during this phase are vertically superimposed. Then, the two sets of eccentric blocks 7 rotate 90 degrees clockwise and simultaneously revolve 90 degrees counterclockwise. Figure 2 As shown in (b), the excitation force generated by the two sets of eccentric blocks 7 in the vertical direction during this phase is vertically superimposed; at the midpoint between the two phases, an oblique force is generated, causing the vibrating wheel 1 to act downwards while simultaneously twisting and kneading, achieving the effect of a rubber-tired roller, making the surface dense and aesthetically pleasing. The two sets of eccentric blocks 7 continue to rotate 90 degrees clockwise and simultaneously revolve 90 degrees counterclockwise, returning the two sets of eccentric blocks 7 to the horizontal direction as shown in (b). Figure 2 As shown in (a).

[0047] The hydraulic pump drives the external gear shaft 14 to rotate, which in turn drives the external gear 16 to rotate. Since the external gear 16 meshes with the internal gear cylinder 15, the rotation of the external gear 16 drives the internal gear cylinder 15 to rotate, which in turn drives the vibrating wheel 1 to rotate. The hydraulic pump also drives the left central shaft 2 to rotate, which in turn drives the central gear 4 to rotate. Since the central gear 4 meshes with the starting gear 5, the rotation of the central gear 4 drives the starting gear 5 to rotate, which in turn drives the vibrating shaft 6 to rotate. The rotation of the vibrating shaft 6 drives the eccentric block 7 to rotate, generating an excitation force. Simultaneously, the hydraulic pump drives the right central shaft 12 to rotate, which in turn drives the coupling rod 11 to rotate. Since the two ends of the coupling rod 11 are connected to the two vibrating shafts 6 through bearings, the rotation of the coupling rod 11 drives the two vibrating shafts 6 to rotate, causing the eccentric block 7 to rotate on its own axis and revolve around the sun.

[0048] For better results, in one embodiment, the edge trimming section further includes a left connecting rod 35 and a right connecting rod 36 respectively connected to the left vibrating plate 34 and the right vibrating plate 29; the upper end of the left connecting rod 35 is connected to a lower left shaft bracket 41, a lower left spherical gear 22 is rotatably connected inside the lower left shaft bracket 41, the lower left spherical gear 22 is meshed with a left flat gear 21, the left flat gear 21 is connected to an upper left shaft bracket 18, and an upper left spherical gear 20 is rotatably connected inside the upper left shaft bracket 18; the upper end of the right connecting rod 36 is connected to a lower right shaft bracket 37, a lower right spherical gear 26 is rotatably connected inside the lower right shaft bracket 37, the lower left spherical gear 26 is meshed with a right flat gear 38, the right flat gear 38 is connected to an upper right shaft bracket 25, and an upper right spherical gear 23 is rotatably connected inside the upper right shaft bracket 25; both the upper left spherical gear 20 and the upper right spherical gear 23 are meshed with a horizontal flat gear 17.

[0049] For better results, in one embodiment, a left vibration shaft 33 is rotatably disposed inside the left vibration plate 34, and a left eccentric block 32 is disposed on the left vibration shaft 33; a right vibration shaft 30 is rotatably disposed inside the right vibration plate 29, and a right eccentric block 31 is disposed on the right vibration shaft 30.

[0050] Furthermore, the horizontal flat gear 17 is mounted on the frame 27, and the horizontal flat gear 17 meshes with the upper left spur gear 20 and the upper right spur gear 23 respectively. The upper left spur gear 20 is mounted on the upper left spur gear shaft 19, and the upper right spur gear 23 is mounted on the upper right spur gear shaft 24. The upper left shaft bracket 18 and the upper right shaft bracket 25 are mounted on the upper left spur gear shaft 19 and the upper right spur gear shaft 24 respectively.

[0051] Left flat gear 21 and right flat gear 38 are respectively mounted on upper left shaft bracket 18 and upper right shaft bracket 25. Lower left spherical gear 22 and lower right spherical gear 26 mesh with left flat gear 21 and right flat gear 38 respectively. Lower left spherical gear 22 and lower right spherical gear 26 are respectively mounted on lower left spherical gear shaft 42 and lower right spherical gear shaft 28. Lower left shaft bracket 41 and lower right shaft bracket 37 are respectively mounted on lower left spherical gear shaft 42 and lower right spherical gear shaft 28.

[0052] The left bushing 40 is connected to the lower left spur gear shaft 42 via a bearing and is fitted onto the left flat gear 21. The left bushing 40 can slide up and down along the left flat gear 21 to ensure that the lower left spur gear 22 is always meshed with the left flat gear 21. The right bushing 39 is connected to the lower right spur gear shaft 28 via a bearing and is fitted onto the right flat gear 38. The right bushing 39 can slide up and down along the right flat gear 38 to ensure that the lower right spur gear 26 is always meshed with the right flat gear 38.

[0053] Left connecting rod 35 and right connecting rod 36 are connected to left lower shaft bracket 41 and right lower shaft bracket 37 respectively. Left vibrating plate 34 and right vibrating plate 29 are connected to left connecting rod 35 and right connecting rod 36 respectively. Left vibrating shaft 33 and right vibrating shaft 30 are installed on left vibrating plate 34 and right vibrating plate 29 respectively. Left eccentric block 32 and right eccentric block 31 are installed on left vibrating shaft 33 and right vibrating shaft 30 respectively.

[0054] The working principle of the edge finishing system is as follows: The hydraulic pump drives the upper left spur gear shaft 19 to rotate, and the rotation of the upper left spur gear shaft 19 drives the upper left spur gear 20 to rotate. Since the horizontal flat gear 17 meshes with the upper left spur gear 20, under the action of the horizontal flat gear 17, the upper left spur gear 20 rotates and moves left and right along the horizontal flat gear 17, driving the upper left spur gear shaft 19 to move left and right. The left and right movement of the upper left spur gear shaft 19 drives the upper left shaft bracket 18 to slide left and right along the horizontal flat gear 17, driving the left flat gear 21, the lower left spur gear 22, the lower left shaft bracket 41, and the left connecting rod 35 to move left and right, realizing the adjustment of the left and right positions of the left vibrating plate 34; The hydraulic pump drives the lower left spur gear shaft 42 to rotate, and the lower left spur gear... The rotation of shaft 42 drives the left lower spherical gear 22 to rotate. Since the left lower spherical gear 22 meshes with the left flat gear 21, under the action of the left flat gear 21 and the left shaft sleeve 40, the left lower spherical gear 22 rotates and moves up and down along the left flat gear 21, driving the left lower shaft bracket 41 and the left connecting rod 35 to move up and down, thereby adjusting the up and down position of the left vibrating plate 34. The hydraulic pump drives the left vibrating shaft 33 to rotate, and the rotation of the left vibrating shaft 33 drives the left eccentric block 32 to rotate. The rotation of the left eccentric block 32 generates a sinusoidal alternating excitation force, which drives the left vibrating plate 34 to vibrate inward at the edge of the mixture, thereby achieving compaction of the edge. It can also shape the left vibrating plate 34 to the right at the edge and fix the left vibrating plate 34 as a sliding template during rolling.

[0055] The hydraulic pump drives the upper right spur gear shaft 24 to rotate, which in turn drives the upper right spur gear 23 to rotate. Since the horizontal flat gear 17 meshes with the upper right spur gear 23, the upper right spur gear 23 rotates while simultaneously moving left and right along the horizontal flat gear 17, causing the upper right spur gear shaft 24 to move left and right. This left and right movement of the upper right spur gear shaft 24 causes the upper right shaft bracket 25 to slide left and right along the horizontal flat gear 17, which in turn causes the right flat gear 38, lower right spur gear 26, lower right shaft bracket 37, and right connecting rod 36 to move left and right, thus adjusting the left and right positions of the right vibrating plate 29. The hydraulic pump drives the upper right spur gear 23 to rotate. The gear shaft 28 rotates, and the rotation of the lower right spur gear shaft 28 drives the lower right spur gear 26 to rotate. Since the lower right spur gear 26 meshes with the right flat gear 38, under the action of the right flat gear 38 and the right bushing 39, the lower right spur gear 26 rotates and moves up and down along the right flat gear 38, driving the lower right shaft bracket 37 and the right connecting rod 36 to move up and down, thereby adjusting the upper and lower positions of the right vibrating plate 29. The hydraulic pump drives the right vibrating shaft 30 to rotate, and the rotation of the right vibrating shaft 30 drives the right eccentric block 31 to rotate. The rotation of the right eccentric block 31 generates a sinusoidal alternating excitation force, which drives the right vibrating plate 29 to vibrate downward at the edge of the mixture, thereby achieving compaction of the edge.

[0056] When the roller travels to the edge, the edge repair system is used. When it travels to the inner position, the left vibrating plate 34 and the right vibrating plate 29 are lifted to carry out normal compaction operations.

[0057] For better results, in one embodiment, the Rayleigh wave excitation device further includes a mounting hinge shaft 50 and an excitation shaft 43. The pull rod 51 is mounted on the hinge shaft 50, and an excitation rod 44 is connected to the excitation shaft 43. A driven spherical gear 49 is rotatably mounted on the end of the pull rod 51. A slider 55 is slidably connected to the excitation rod 44, and a coupling 56 is connected to the slider 55. The coupling 56 is connected to an excitation spherical gear shaft 47, and an excitation spherical gear 46 is mounted on the excitation spherical gear shaft 47.

[0058] Furthermore, the guide cylinder 52, mounting hinge shaft 50, and excitation shaft 43 are mounted on the frame 27. The excitation hammer 54 is located in the guide cylinder 52 and can slide up and down along the guide cylinder 52. The function of the guide cylinder 52 is to ensure that the excitation hammer 54 falls vertically. The lower end of the pull rope 53 is connected to the excitation hammer 54, and the upper end is connected to the pull rod 51. The pull rod 51 is fixed on the mounting hinge shaft 50 to form a lever structure. The driven spur gear shaft 48 is fixed to the tail of the pull rod 51, and the driven spur gear 49 is mounted on the driven spur gear shaft 48.

[0059] An excitation rod 44 is mounted on an excitation shaft 43. A slider 55 has a sliding hole and is mounted on the excitation rod 44 through the sliding hole, allowing it to slide along the rod. An excitation spring 45 is sleeved on the excitation rod 44 and is located between the slider 55 and the excitation shaft 43. A coupling 56 consists of a sleeve and a bearing. The sleeve is fixed to the slider 55. An excitation gear shaft 47 is mounted on the bearing of the coupling 56, and an excitation gear 46 is mounted on the shaft 47. The function of the coupling 56 is to ensure that the excitation gear shaft 47 can both rotate and slide.

[0060] The working principle of the Rayleigh wave excitation device is as follows: Currently, there are four main methods for detecting the compaction degree of asphalt pavement 66: core sampling, nuclear density meter, radar meter, and Rayleigh wave meter. Core sampling is a destructive testing method, suitable only for inspection and evaluation, not for quality control during construction. Nuclear density meters and radar meters can be used for quality control during construction, but their biggest drawback is that while they are accurate for homogeneous surfaces, the results for non-homogeneous surfaces are highly variable. Asphalt pavement 66 is non-homogeneous, making these two instruments inaccurate for compaction degree detection. Rayleigh wave meters, due to their strong penetrating power, can achieve high accuracy even for non-homogeneous surfaces. Therefore, this invention uses a Rayleigh wave meter to detect compaction degree. The Rayleigh wave excitation device is installed on one side of the road roller. When the road roller travels to the edge of the colored asphalt pavement 66, the excitation hammer 54 strikes the shoulder outside the colored asphalt pavement 66, emitting Rayleigh waves. The detector 58 collects the signals, which are then calculated and analyzed by specialized software to determine the compaction degree at different measuring points. This method is simple, accurate, and can detect multiple locations with a single emission, resulting in high detection efficiency.

[0061] In the initial position, the excitation hammer 54 is at its lowest point under the influence of gravity, while the driven sprocket 49 at the tail of the lever 51 is at its highest point due to the lever action. The hydraulic pump drives the excitation shaft 43 to rotate clockwise, which in turn drives the excitation rod 44 to rotate, causing the excitation sprocket 46 at the top of the excitation rod 44 to mesh with the driven sprocket 49. The excitation shaft 43 and the excitation rod 44 continue to rotate, and the hydraulic pump drives the excitation sprocket shaft 47 to rotate clockwise, causing the excitation sprocket 46 to rotate. Since the excitation sprocket 46 meshes with the driven sprocket 49, the rotation of the excitation sprocket 46 causes the driven sprocket 49 to rotate while moving downwards and to the left, causing the left end of the lever 51 to rotate downwards. Under the action of the lever... The right end of the pull rod 51 rotates upward, and the pull rope 53 pulls the excitation hammer 54 upward along the guide cylinder 52, causing the excitation hammer 54 to gradually rise off the ground and gain a certain potential energy; the excitation gear 46 exerts force on the driven gear 49 while also being subjected to the reaction force of the driven gear 49. Under the action of the coupling 56, the slider 55 overcomes the elastic force of the excitation spring 45 (at this time the spring is compressed) and moves along the excitation rod 44 towards the axis (inward), driving the excitation gear 46 to rotate while moving towards the axis; when the excitation gear 46 and the driven gear 49 are at the same horizontal position, the excitation spring 45 reaches its maximum compression, the driven gear 49 reaches its leftmost position, and the pull rod 51 and the excitation rod 44 overlap vertically (see...). Figure 5 The excitation rod 44 and the excitation gear 46 continue to rotate, causing the driven gear 49 to rotate and move downwards and to the right. This causes the left end of the pull rod 51 to continue rotating downwards, and the right end of the pull rod 51 to continue rotating upwards under the action of the lever. The pull rope 53 pulls the excitation hammer 54 to continue moving upwards along the guide cylinder 52, causing the excitation hammer 54 to continue to rise. As the driven gear 49 moves downwards and to the right, the excitation gear 46 rotates and moves downwards and to the right along with the slider 55 under the elastic force of the excitation spring 45. When the driven sprocket 49 reaches its highest point and symmetrical position along the axial direction (when the driven sprocket 49 is at its lowest position), the excitation sprocket 46 and the driven sprocket 49 are at the critical point of engagement, at which point the excitation hammer 54 is at its highest position. The excitation rod 44 and the excitation sprocket 46 continue to rotate, the excitation sprocket 46 disengages from the driven sprocket 49, the driven sprocket 49 is released from its constraint, and the excitation hammer 54 falls freely downwards under the influence of gravity, converting thermal energy into kinetic energy. The excitation hammer 54 impacts the road shoulder, emitting a Rayleigh wave. The excitation rod 44 continues to rotate, and another excitation sprocket 46 engages with the driven sprocket 49, emitting a Rayleigh wave for the second time… and so on, repeating this cycle to complete the Rayleigh wave emission.

[0062] For better results, in one embodiment, the detector placement device further includes a crossbar 60 and a rotatably mounted cam 61. The cam 61 is in contact with the crossbar 60. The crossbar 60 is connected to the vertical rod 65. A slide cylinder 64 is slidably connected to the outside of the vertical rod 65. A vertical rod spring 57 is sleeved on the vertical rod 65 between the slide cylinder 64 and the crossbar 60.

[0063] Furthermore, the camshaft 62 and the slide cylinder 64 are mounted on the frame 27. The cam 61 is mounted on the camshaft 62, and the cam 61 is in contact with the crossbar 60. The crossbar 60 is perpendicularly connected to the vertical rod 65. The vertical rod 65 is inside the slide cylinder 64 and can slide up and down along the slide sleeve.

The slide cylinder connecting rod 63 connects all the slide cylinders 64 together. The detector 58 is mounted on the lower end of the vertical rod 65. The crossbar 60 and the slide cylinder connecting rod 63 are foldable so that they can be stored away when not in use to save space.

[0064] The working principle of the detector deployment device is as follows: The detector deployment device is installed at the lower part of the frame 27 (close to the road surface 66). The hydraulic pump drives the camshaft 62 to rotate, which in turn drives the cam 61 to rotate. The rotation of the cam 61 drives the horizontal bar 60 to move up and down, which in turn drives the vertical bar 65 to move up and down within the slide cylinder 64, thus realizing the intermittent contact of the detector 58 with the colored asphalt road surface 66. The contact of the detector 58 with the road surface 66 is synchronized with the Rayleigh wave emission.

[0065] For better results, in one embodiment, the compaction detection unit also includes a data acquisition and analysis subsystem, which consists of a detector, Wi-Fi, computer hardware, and analysis software.

[0067] For better results, in one embodiment, the flatness detection unit further includes a second middle spherical gear 76, a left spherical gear 73, and a right spherical gear 78 that are rotatably configured. The second middle spherical gear 76 is meshed with the left spherical gear 73 and the right spherical gear 78, respectively. The left spherical gear 73 is rotatably connected to the upper end of the left connecting rod 71, and the right spherical gear 78 is rotatably connected to the upper end of the right connecting rod. The lower ends of the left connecting rod 71 and the right connecting rod are both connected to the three-meter ruler box 68.

[0068] For better results, in one embodiment, the lower part of the three-meter ruler box 68 is provided with an inner cylinder 83, and a displacement sensor 81 is provided on the side of the inner cylinder 83. The inner cylinder 83 is provided with an inner top plate 85, an upper spring 82 and a lower spring 86. The upper spring 82 is located above the inner top plate 85. An inner top rod is connected to the bottom of the inner top plate 85. The lower spring 86 is sleeved on the inner top rod. The inner top rod is connected to the movable feeler gauge 67.

[0069] Furthermore, the second intermediate spur gear shaft 75, the left spur gear shaft 74, and the right spur gear shaft 77 are all mounted on the frame 27. The second intermediate spur gear 76, the left spur gear 73, and the right spur gear 78 are respectively mounted on the second intermediate spur gear shaft 75, the left spur gear shaft 74, and the right spur gear shaft 77. The second intermediate spur gear 76 meshes with the left spur gear 73 and the right spur gear 78 respectively. The left spur gear hinge shaft 72 and the right spur gear hinge shaft are respectively mounted on the left spur gear 73 and the right spur gear 78.

[0070] The upper end of the left connecting rod 71 is connected to the left circular gear hinge shaft 72, and the lower end is connected to the lower left hinge shaft. The upper end of the right connecting rod is connected to the right circular gear hinge shaft, and the lower end is connected to the lower right hinge shaft 80. The three-meter ruler box 68 is connected to the left connecting rod 71 and the right connecting rod through the lower left hinge shaft and the lower right hinge shaft 80.

[0071] The counterweight 70 is connected to the protrusion 84 at the bottom, and the three-meter ruler box 68 is provided with a sliding groove 69 at the top. The counterweight 70 can slide left and right along the three-meter ruler box 68 through the protrusion 84 and the sliding groove 69.

[0072] The inner cylinder 83 is located in the lower part of the three-meter ruler box 68. The upper spring 82, lower spring 86, inner top plate 85, inner top rod, movable feeler gauge 67, and displacement sensor 81 are all located in the inner cylinder 83. The upper spring 82 is located at the top, the inner top plate 85 is below the upper spring 82, the inner top rod is vertically connected to the inner top plate 85, the lower spring 86 is located between the inner top plate 85 and the middle ruler opening and is sleeved on the inner top rod; the movable feeler gauge 67 is connected to the lower end of the inner top rod and can slide up and down along the ruler opening.

[0073] The entire smoothness testing system is densely equipped with multiple movable feeler gauges 67. When there is a gap between the three-meter ruler box 68 and the road surface 66, the movable feeler gauge 67 extends out of the three-meter ruler box 68 from the gauge outlet, and the extended part is the smoothness value at that point. When the three-meter ruler box 68 is in close contact with the road surface 66, the movable feeler gauge 67 is fully inserted into the three-meter ruler box 68, and the average value of all measuring points is the smoothness value at that point.

[0074] The working principle of the road surface evenness inspection system is as follows: Currently, evenness inspection methods include a three-meter straightedge with a feeler gauge, an eight-wheel roller, a laser evenness meter, and a bump accumulator. The three-meter straightedge is the most classic inspection technology. Both the eight-wheel roller and the laser evenness meter utilize the same principle. However, due to the limited workload of colored asphalt concrete pavement (Project 66), the laser evenness meter and bump accumulator cannot be deployed, the eight-wheel roller is inconvenient to use during construction, and manual inspection with a three-meter straightedge is too slow. This invention installs the evenness inspection system on the side of the road roller, using a continuous three-meter straightedge in conjunction with a feeler gauge for automatic evenness inspection. This allows for evenness control during construction, avoiding the shortcomings of post-construction inspections.

[0075] The hydraulic pump drives the second intermediate sprocket shaft 75 to rotate. The rotation of the second intermediate sprocket shaft 75 drives the second intermediate sprocket 76 to rotate. The rotation of the second intermediate sprocket 76 drives the left sprocket 73 and the right sprocket 78 to rotate. The rotation of the left sprocket 73 and the right sprocket 78 drives the left sprocket hinge shaft 72 and the right sprocket hinge shaft to rotate. The rotation of the left sprocket hinge shaft 72 and the right sprocket hinge shaft drives the left connecting rod 71 and the right connecting rod to move up and down. The up and down movement of the left connecting rod 71 and the right connecting rod drives the three-meter straight... The ruler box 68 moves up and down. When the left and right sprocket hinge shafts 72 and 72 reach their lowest points, both ends of the three-meter ruler box 68 are in contact with the road surface 66. When there is a gap between the three-meter ruler box 68 and the road surface 66, the movable feeler gauge 67 extends out of the ruler box 68 from its outlet; the extended portion is the flatness value at that point. When the three-meter ruler box 68 is in close contact with the road surface 66, the movable feeler gauge 67 is fully inserted into the three-meter ruler box 68, and the average value of all measuring points is the flatness value at that point. After the first three-meter length is measured, the second sprocket 76 continues to rotate, and the three-meter ruler box 68 leaves the ground. As the road roller moves forward, the three-meter ruler box 68 moves forward synchronously. When the left and right sprocket hinge shafts 72 and 72 reach their lowest points again, the flatness of the next three-meter section is measured. This cycle repeats until all flatness measurements are completed.

[0076] For better results, in one embodiment, the friction coefficient detection unit further includes a rotatable detection spur gear 88, which meshes with a vertical horizontal gear 90, and the vertical horizontal gear 90 is connected to the friction block 91.

[0077] Furthermore, the detection spur gear shaft 87 and the flat gear sleeve 89 are mounted on the frame 27. The detection spur gear 88 is mounted on the detection spur gear shaft 87. The detection spur gear 88 meshes with the vertical flat gear 90. The vertical flat gear 90 is located inside the flat gear sleeve 89 and can slide up and down along the flat gear sleeve 89. The flat gear sleeve 89 ensures that the detection spur gear 88 and the vertical flat gear 90 are always meshed. The friction block 91 is mounted on the lower part of the vertical flat gear 90, and the force sensor 92 is connected to the friction block 91.

[0078] The working principle of the friction coefficient detection system is as follows: The friction coefficient detection system is installed at the bottom of the roller frame 27. As the roller moves forward, the friction coefficient is continuously detected by detecting the forward and reverse rotation of the circular gear shaft 87.

[0079] The hydraulic pump drives the detection sprocket shaft 87 to rotate, which in turn drives the detection sprocket 88 to rotate. The detection sprocket 88 meshes with the vertical gear 90. The rotation of the detection sprocket 88 drives the vertical gear 90 to move downward, which in turn drives the friction block 91 to move downward. As the whole machine moves forward, it generates a forward force on the friction block 91. The pressed friction block 91 contacts the road surface 66 and generates a backward friction force. The force sensor 92 reads the normal force and friction force and calculates the coefficient of friction.

[0080] For better results, in one embodiment, the special roller for colored asphalt concrete pavement further includes a permeability detection unit and a width and elevation detection unit. The permeability detection unit is an infrared permeability detection device, which is available as a finished product on the market. The width and elevation detection unit uses a rangefinder and a total station to detect the width and elevation.

[0081] For better results, in one embodiment, the special roller for colored asphalt concrete pavement also includes an information acquisition, statistical analysis and control system, which consists of an information acquisition, statistical analysis subsystem and a control subsystem.

[0082] The information acquisition, statistical analysis, and analysis subsystem consists of various transmitters, sensors, data acquisition devices, Wi-Fi, computer hardware, and analysis software.

[0083] The control subsystem consists of control elements, control software, operating switches, etc.

[0084] The information collection, statistical analysis, and processing subsystem transmits various data reserves to the control system, which then generates operation instructions.

[0085] The control system can control the operation of the walking system, vibration system, edge finishing system, compaction testing system, flatness testing system, permeability testing system, width and elevation testing system, and friction coefficient testing system. It can control the walking speed and direction, adjust the magnitude, amplitude, and frequency of the excitation force, adjust the main position of edge finishing, control the frequency of compaction testing, and control the speed and position of flatness, permeability, width and elevation, and friction coefficient testing.

[0086] The special road roller for colored asphalt concrete pavement based on the vibration mixing pavement system of the present invention has the following characteristics:

[0087] (1) The structure of two cantilever shafts and two vibration shafts 6 is adopted. The two vibration shafts 6 are connected by a coupling rod 11. The two sets of eccentric blocks 7 rotate in the same direction and revolve in opposite directions, so that the excitation force generated by the two sets of eccentric blocks 7 is always superimposed in the vertical direction and there is no horizontal component force.

[0088] (2) There is no component force to cancel each other in all directions, no internal kinetic energy loss, high energy utilization rate, which is conducive to energy conservation and emission reduction and conforms to the current trend of energy conservation and environmental protection.

[0089] (3) The excitation forces generated by the two sets of eccentric blocks 7 in the horizontal and vertical directions alternate vertically, without generating horizontal component forces, resulting in high compaction efficiency and good compaction effect; the excitation force is large under the same roller weight, and the roller weight can be reduced under the same excitation force.

[0090] (4) The excitation forces generated by the two sets of eccentric blocks 7 in the horizontal and vertical directions alternately overlap vertically. At the position between the two phases, an oblique force is generated, which causes the vibrating wheel 1 to act downward while twisting and kneading, achieving the effect of a rubber-tired roller and making the surface dense.

[0091] (5) High surface flatness. Since no horizontal component force is generated, no horizontal displacement will occur during pressing, which improves the flatness.

[0092] (6) Stable surface color. Since there is no horizontal component force, the horizontal friction between the compaction wheel and the surface of the colored asphalt concrete pavement 66 is reduced, so that the colored asphalt mortar is evenly distributed. At the same time, it does not damage the surface oil film, and does not produce looseness and micro-cracks, so that the colored asphalt concrete pavement 66 has a uniform, stable and beautiful color.

[0093] (7) During construction, the flatness, permeability, width and elevation and friction coefficient are tested simultaneously to achieve process control during construction, avoid "post-mortem examination", reduce the labor intensity of testing and improve the quality of the project.

[0094] In summary, the special road roller for colored asphalt concrete pavement based on a vibration mixing system of the present invention consists of a vibration section, an edge finishing section, a compaction degree testing section, a smoothness testing section, and a friction coefficient testing section. The vibration section drives the vibrating wheel 1 to rotate, simultaneously driving the eccentric block 7 to rotate on its own axis and revolve around the center, thereby compacting the pavement 66. The edge finishing section adjusts the positions of the left vibrating plate 34 and the right vibrating plate 29, respectively, to finish the edges of the pavement 66 through their vibration. The compaction degree testing section includes a Rayleigh wave excitation device and a detector placement device. The Rayleigh wave excitation device drives the pull rod 51 to rotate, thereby causing the excitation hammer 54 to move upwards to complete the compaction. Rayleigh waves are emitted during free fall; the detector deployment device moves the detector 58 by driving the vertical rod 65 up and down to intermittently contact the road surface 66; the smoothness detection unit moves the three-meter straightedge box 68 up and down to make it fit the road surface 66, and performs smoothness detection through the movable feeler gauge 67 inside; the friction coefficient detection unit moves the friction block 91 up and down, causing the force sensor 92 on it to contact the road surface 66 to perform friction coefficient detection; through the cooperation of each part, the special road roller for colored asphalt concrete pavement based on the vibration mixing road system of the present invention can improve the compaction quality of colored asphalt concrete pavement, ensure the color stability of colored asphalt concrete pavement, and improve compaction efficiency and quality.
