Description

Technical Field

[0001] The present invention relates to the technical field of road maintenance, and in particular to a road surface maintenance and detection integrated device. Background Art

[0002] After a road has been open to traffic for a period of time, whether it is an asphalt pavement or a cement pavement, some early defects will appear to a greater or lesser extent. Common ones include cracks, potholes, rutting, looseness and surface damage. Among them, road cracks are the most common, most prone to occur and one of the earliest defects. They not only affect the appearance of the road and driving, but also easily allow rainwater to enter the surface structure, causing structural damage to the road, resulting in a decrease in the bearing capacity of the road surface and shortening the service life of the road. Therefore, it is necessary to use maintenance and inspection equipment to repair and inspect the road surface.

[0003] However, most road surface repairs on the market are done by workers pushing a caulking vehicle to move along the road cracks. However, when dealing with curved sections and cracks of complex shapes, the caulking tends to deviate from the center, making it difficult to achieve accurate filling, resulting in incomplete crack repair and affecting the overall performance of the road. In addition, the manual operation process will cause the caulking material to be filled unevenly, and problems such as bubbles and local accumulation may occur, which reduces the adhesion between the caulking material and the gap, thereby affecting the caulking quality and shortening the service life of the road. In addition, for narrow or irregular cracks, manual caulking makes it difficult to determine whether the caulking material is filled evenly, affecting the road maintenance effect.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In order to solve the technical problem of incomplete repair and filling caused by the bending of pavement gaps during road surface repair, such as Figure 1-Figure 3 As shown, the following preferred technical solutions are provided:

[0034] A road surface repair and inspection device includes an electric cart 1, fixedly connected to a repair slurry mixing tank 2. A first material discharge assembly 3 is mounted on the electric cart 1. The first material discharge assembly 3 includes a first delivery pipe 31 connected to the side wall of the repair slurry mixing tank 2, connected to a first delivery pump 32, and fixedly connected to the top surface of the electric cart 1. A first support block 33 is fixedly connected to the side wall of the electric cart 1 and fixedly engages with the first delivery pipe 31. A first mounting base 34 is fixedly connected to the side wall of the electric cart 1, and a first cylinder 35 is fixedly connected to the first mounting base 34. The output end of the first cylinder 35 is fixedly connected to a first connecting bracket 36, which is fixedly engaged with the first delivery pipe 31. A visual probe 5 is fixedly connected to the bottom surface of the electric cart 1 and electrically connected to the first cylinder 35. The visual probe 5 uses industrial-grade line laser scanning technology to capture data such as the tortuous direction and width changes of cracks in real time.

[0035] Specifically, as roads age, both asphalt and cement pavements will develop varying degrees of early-stage defects. Common defects include cracks, potholes, rutting, looseness, and surface damage. Cracks are the most common and the first type of defect to appear. When cracks appear on the road surface, repairs must be carried out promptly.

[0036] The specific maintenance process is: pour one of the required repair materials such as asphalt, concrete, cement, etc. into the repair slurry mixing tank 2, heat and stir to form a filling material, and the staff uses the electric cart 1 to move the equipment to the diseased road section and pre-enter the control instructions such as the driving path, operating parameters, direction and position.

[0037] After preparation is complete, the electric cart 1 is started and the vehicle moves along a preset path. During this process, the visual probe 5 scans the cracks in the road surface in real time. For irregular crack trajectories, such as complex shapes such as continuous S-shapes, the visual probe 5 converts the crack trajectory image obtained by the scan into an electrical signal and transmits it to the first cylinder 35. The first cylinder 35 accurately controls the extension distance based on the received electrical signal, so that it drives the first connecting sleeve 36 fixed on the end side to move horizontally. Since the first delivery pipe 31 is fixedly connected to the first connecting sleeve 36, the first cylinder 35 can drive the first delivery pipe 31 to move horizontally when driving the first connecting sleeve 36 to move horizontally, so that the grouting position of the first delivery pipe 31 is adjusted, thereby ensuring that the first delivery pipe 31 accurately fits the crack trajectory to complete the grouting operation, realizing full automation of the process. When the first delivery pipe 31 is adjusted to the appropriate position, the first delivery pump 32 is started, so that the first delivery pump 32 controls the caulking material in the repair slurry mixing tank 2 to fall through the first delivery pipe 31 into the road surface gap for filling.

[0038] Compared with traditional manual grouting operations, this device has significant effects. First, through visual recognition and automatic control systems, it can accurately control the driving trajectory of the grouting vehicle, effectively solving the problem of grouting of curved sections and complex-shaped cracks that is easy to deviate from the center, and greatly improving the grouting accuracy; second, automatic control ensures that the grouting material is evenly filled, avoiding speed and pressure fluctuations caused by manual operation, and significantly improving the grouting quality; third, it reduces manual intervention, and operators do not need to continuously push the equipment, control the direction and speed, which reduces labor intensity while significantly improving work efficiency and speeding up construction progress; fourth, precise grouting control avoids material waste and effectively reduces construction costs.

[0039] In addition, a section of the first conveying pipe 31 adopts a corrugated design to ensure that it is flexible during the horizontal adjustment process, does not affect the stable delivery of the filling material, and provides reliable protection for the filling operation.

[0040] In order to solve the technical problem that bubbles will be generated when the repair material is poured, and the bubbles will be poured into the road cracks along with the material, making the surface of the filling material uneven, reducing the contact area between the filling material and the crack surface, and causing the bonding force to decrease, such as Figure 1-Figure 2 , Figure 4-Figure 8 As shown, the following preferred technical solutions are provided:

[0041] A second blanking component 4 is installed on the electric trolley 1, and the second blanking component 4 includes a second conveying pipe 41 connected to the side wall of the repair slurry mixing tank 2, and the second conveying pump 42 is connected to the second conveying pump 42, and the second conveying pump 42 is fixedly connected to the top surface of the electric trolley 1, and a second support block 43 is fixedly connected to the side wall of the electric trolley 1, and the second support block 43 is fixedly sleeved with the second conveying pipe 41. A second mounting seat 44 is fixedly connected to the side wall of the electric trolley 1, and a second cylinder 45 is fixedly connected to the second mounting seat 44. The output end of the second cylinder 45 is fixedly connected to a second connecting sleeve 46, and the second connecting sleeve 46 is fixedly sleeved with the second conveying pipe 41. The second cylinder 45 is electrically connected to the visual probe 5, and the repair slurry mixing tank 2 forms a closed-loop conveying link with the second conveying pump 42 through the second conveying pipe 41. The second conveying pump 42 can dynamically adjust the flow rate according to the grouting requirements to ensure stable output of filling material.

[0042] The electric cart 1 is equipped with a defoaming assembly 6, which includes a hydraulic column 61 fixedly connected to the top surface of the electric cart 1. The output end of the hydraulic column 61 is fixedly connected to a slide 62, and the bottom of the slide 62 is fixedly connected to a pressure plate 63. A vibrating rod 610 is installed in the pressure plate 63, and an infrared scanner 9 is installed in the pressure plate 63. The pressure plate 63 has a placement slot 8 for the infrared scanner 9. A transparent protective plate 10 is fixedly connected to the bottom surface of the pressure plate 63. The outer contour of the transparent protective plate 10 matches the inner contour of the placement slot 8. The transparent protective plate 10 is made of scratch-resistant and wear-resistant polycarbonate, which can not only ensure scanning accuracy but also prevent the adhesion of caulking material and affect the detection effect.

[0043] A groove 64 is provided inside the clamping plate 63, and an electric push rod 65 is fixedly connected to the inner wall of the groove 64. There are multiple electric push rods 65 and vibrating rods 610, and multiple electric push rods 65 are electrically connected to the visual probe 5. The output end of the electric push rod 65 is fixedly connected to the piston rod 66, and the end side of the piston rod 66 is fixedly connected to the connecting column 67. The two sides of the connecting column 67 are fixedly connected to the limiting blocks 68. The side walls of the clamping plate 63 connected to the groove 64 are all provided with sliding grooves 69, and the limiting blocks 68 are slidably connected to the sliding grooves 69.

[0044] The vibrating rod 610 is fixedly connected to the connecting column 67. A cavity 611 is opened inside the vibrating rod 610. A fixing plate 612 is fixedly connected in the cavity 611. A motor 613 is fixedly connected to the top surface of the fixing plate 612. The output end of the motor 613 is fixedly connected to the eccentric shaft block 614. A bearing 615 is installed in the cavity 611. The eccentric shaft block 614 is rotatably connected to the bearing 615.

[0045] Specifically, the electric trolley 1 moves and drives the first conveying pipe 31 to perform grouting along the crack path. When the second conveying pipe 41 on the electric trolley 1 is located at the initial position of the first conveying pipe 31 as the electric trolley 1 moves, the electric trolley 1 automatically stops at this time, and then the electric trolley 1 retreats and resets, so that the electric trolley 1 is in the initial position. At this time, the defoaming component 6 is above the grouted gap, and then the visual probe 5 scans and converts the acquired crack track image into an electrical signal and transmits it to multiple electric push rods 65, such as Figure 2 、 Figure 5 and Figure 6 As shown, multiple electric push rods 65 drive the piston rod 66 to extend or retract a corresponding distance after receiving an electrical signal. Since the piston rod 66 is fixedly connected to the connecting column 67, the limit block 68 is fixedly connected to the connecting column 67, and the limit block 68 is slidably connected to the slide groove 69, during the extension and retraction of the piston rod 66, the connecting column 67 will synchronously drive the limit block 68 to move horizontally along the slide groove 69. Since the connecting column 67 is fixedly connected to the vibrating rod 610, during the movement of the connecting column 67, the vibrating rod 610 will be adjusted to a position adapted to the crack trajectory as the connecting column 67 is adjusted.

[0046] Then start the hydraulic column 61. In the initial state, the hydraulic column 61 is in a state of extending a distance, and the connecting rod 72 is in a horizontal state. When the hydraulic column 61 is started, as shown in FIG. Figure 1-Figure 2 As shown, the hydraulic column 61 is forced to drive the slide 62 to contract, so that the slide 62 is forced to drive the fixed pressure plate 63 below to move downward. Since the connecting block 73 is fixedly connected to the slide 62, the connecting block 73 is hinged to the connecting rod 72, and the connecting rod 72 is rotatably connected to the connecting rod 74. Therefore, in the process of the slide 62 moving downward, the connecting block 73 fixed thereto will be forced to move downward, and the connecting rod 72 hinged to the connecting block 73 will be forced to rotate around the bracket 71. As the connecting rod 72 rotates, the connecting rod 74 rotatably installed with it will be forced to move upward, thereby driving the slide plate 75 below the connecting rod 74 to move upward, so that the bucket 710 installed on the slide plate 75 through the rotating shaft 77 will rise immediately, so that the bucket 710 of the electric cart 1 will not always be in contact with the ground during the movement, thereby reducing damage to the bucket 710.

[0047] As the pressing plate 63 moves downward, the vibrating rod 610 installed inside it will immediately move downward into the corresponding crack. When the vibrating rod 610 enters the crack, the pressing plate 63 fits the road surface. Figure 6-8 As shown, the motor 613 is then started to drive the eccentric shaft block 614 to rotate. As the eccentric shaft block 614 rotates, centrifugal force is generated, which in turn transmits force to the bearing 615 and the vibrating rod 610. The magnitude and direction of the centrifugal force change continuously with the rotation of the eccentric block, causing the end of the vibrating rod 610 to generate high-frequency vibrations. This vibration force can disturb the air bubbles in the filling material, so that the fluidity of the filling material around the bubbles increases under the action of vibration, and the bubbles can more easily overcome the resistance of the surrounding materials and rise to the surface, thereby achieving a defoaming effect. In addition, the movement of the vibrating rod 610 can cause the filling material to flow and stir in the gap, so that the filling material can be better filled into every corner of the gap, including some narrow or irregular parts, thereby avoiding local accumulation of the filling material and making the distribution of the filling material in the gap more uniform.

[0048] As the vibrating rod 610 vibrates and defoams, the defoamed caulking material will drop. When the defoaming process of the vibrating rod 610 is completed, the hydraulic column 61 is started to drive the slide 62 to extend upward for a distance. As the slide 62 rises, the clamping plate 63 fixed to it will rise immediately, so that the multiple vibrating rods 610 in the clamping plate 63 will be separated from the cracks in the road surface. At the same time, the connecting block 73 on the end side of the slide 62 will synchronously drive the connecting rod 72 to rotate, so that the connecting rod 72 is in a horizontal state. The slide plate 75 installed on the connecting rod 72 through the connecting rod 74 will synchronously drive the bucket 710 installed through the rotating shaft 77 to drop. At this time, the bucket 710 drops but will not stick to the ground.

[0049] like Figure 5 As shown, an infrared scanner 9 is installed in the placement slot 8 of the pressing plate 63. The infrared scanner 9 can scan and observe the filling status of the filling material through the transparent protective plate 10. When the infrared scanner 9 scans that the filling material is still flush with the road surface crack after being vibrated, it can be determined that the road surface crack is repaired evenly. When it is determined that the crack is repaired evenly, the information scanned by the infrared scanner 9 is transmitted to the electric cart 1, so that the electric cart 1 continues to move and performs the above operation again at the next distance.

[0050] When the infrared scanner 9 scans that the filling material is vibrated and the filling material at the highest point is not flush with the road crack, it can be detected that there is a height difference on the surface of the filling material, and then it can be determined that the road surface crack is not repaired evenly, and it needs to be re-filled. The infrared scanner 9 converts the scanned information into data and transmits a signal to the electric cart 1. After receiving the signal, the electric cart 1 drives itself to the initial position of the second conveying pipe 41. After the electric cart 1 reaches the initial position, it is started to move. The vehicle moves along the preset path during movement. In this process, the visual probe 5 scans the road crack in real time. For irregular crack trajectories, such as complex shapes such as continuous S-shapes, the visual probe 5 converts the crack trajectory image obtained by scanning into an electrical signal and transmits it to the second cylinder 45. The second cylinder 45 accurately controls the telescopic distance according to the received electrical signal, so that it drives the second connecting sleeve 46 fixed on the end side to move horizontally. Since the second conveying pipe 41 is fixedly connected to the second connecting sleeve 46, the second cylinder 45 can drive the second conveying pipe 41 to move horizontally when driving the second connecting sleeve 46 to move horizontally, so that the grouting position of the second conveying pipe 41 can be adjusted, thereby ensuring that the conveying pipe accurately fits the crack trajectory to complete the supplementary grouting operation.

[0051] After the first delivery pipe 31 is adjusted to a suitable position, the second delivery pump 42 is started, so that the second delivery pump 42 controls the filling material in the repair slurry mixing tank 2 to fall into the road surface gap through the second delivery pipe 41 for re-filling operation. As the filling material continues to fill, the filling material at the bottom will fill the bottom of the crack after being vibrated and defoamed, so the filling material that continues to be replenished will not leak. Therefore, as the second delivery pipe 41 continues to fill, when the infrared scanner 9 scans that the gap between the filling material and the road surface layer is filled to a flush state, it can be determined that the road surface crack is repaired evenly, and the system determines that the repair is completed. The electric cart 1 continues to move forward and circulates the crack repair operation.

[0052] In order to solve the technical problem that when the filler is filled too much, the overflowing filler material will spread to the road surface to form irregular bulges or lumps, causing bumps and collisions during subsequent use, reducing the quality of maintenance, such as Figure 1-Figure 2 , Figures 9-12 As shown, the following preferred technical solutions are provided:

[0053] A cleaning assembly 7 is installed on the electric trolley 1. The cleaning assembly 7 includes a connecting block 73 fixedly connected to the end side of the slide 62. The end side of the connecting block 73 is hinged with a connecting rod 72. The other end of the connecting rod 72 is rotatably connected to a connecting rod 74. Slides 75 are fixedly connected to both sides of the connecting rod 74. The inner wall of the slide 75 is rotatably connected to a rotating shaft 77, and a bucket 710 is fixedly connected to the rotating shaft 77.

[0054] The top surface of the electric trolley 1 is fixedly connected to a bracket 71, a connecting rod 72 is rotatably connected to the bracket 71, a protrusion 76 is fixedly connected to the side wall of the slide 75, and a resistance block 78 is fixedly connected to the rotating shaft 77. The protrusion 76 and the resistance block 78 are arranged on the same circumferential surface.

[0055] like Figure 12 As shown, a torsion spring 79 is sleeved on the rotating shaft 77, and a gear 711 is fixedly sleeved on the rotating shaft 77. The two ends of the torsion spring 79 are fixedly connected to the slide plate 75 and the adjacent side walls of the gear 711 respectively. A tooth plate 712 is fixedly connected to the bottom surface of the electric cart 1. The gear 711 and the tooth plate 712 are engaged with each other. The gear 711 and the tooth plate 712 are aligned in the same vertical direction, and a collection box 713 is installed on the side wall of the electric cart 1.

[0056] Torsion spring 79, sleeved on shaft 77, generates torque and stores energy during the rotation of gear 711. When slide 75 moves downward and gear 711 disengages from tooth plate 712, torsion spring 79 releases its elastic potential energy, driving shaft 77 to rotate rapidly, thus resetting bucket 710. The circumferential limit design of the bump 76 on the side wall of slide 75 and the abutment block 78 on shaft 77 ensures that bucket 710 remains precisely in its initial position flush with the ground after resetting, ready for the next cleaning operation. This design eliminates the need for additional positioning devices and achieves automatic resetting through the coordination of mechanical structures.

[0057] Specifically, according to the second embodiment, during the supplementary grouting process, due to the fluidity of the grouting material, some of it will inevitably overflow. When the material overflows the road surface and dries, it will adhere to the ground on both sides of the crack, causing the overall road surface to look uneven and unsightly, seriously affecting the visual effect of the road. At the same time, the extruded material will form irregular protrusions or lumps, which will cause bumps and collisions when the vehicle is driving, reducing the maintenance quality of the road.

[0058] Therefore, after the electric cart 1 is repaired and caulked for the second time, the overflowed caulking material needs to be further processed. Figure 1-Figure 2 、 Figures 9-12 As shown, the hydraulic column 61 is started to extend it upward for a distance again. As the hydraulic column 61 extends, the slide 62 fixed thereto moves upward immediately, and drives the connecting block 73 fixed on the end side to move upward synchronously, and the connecting rod 72 hinged on the end side of the connecting block 73 also moves upward accordingly. Since the connecting rod 72 is rotatably connected to the bracket 71, the connecting rod 72 rotates during its upward movement, so that one end of the connecting rod 72 moves upward and the other end moves downward accordingly. The connecting rod 74 rotatably connected thereto drives the slides 75 on both sides to slide downward along the electric trolley 1, as shown in FIG. Figure 8As shown, as the slide plate 75 slides down, the bucket 710 installed between the slide plates 75 on both sides through the rotating shaft 77 will also slide down until it is close to the road surface. In this way, when the electric cart 1 moves for secondary filling, the bucket 710 can move in line with the ground, thereby removing the excess filling material, effectively cleaning up the overflowed filling material, and avoiding its residue causing uneven and unsightly road surface, affecting the visual effect of the road, and at the same time preventing the overflowed material from forming irregular protrusions or lumps, thereby ensuring the stable use of the subsequent road surface and improving the maintenance quality.

[0059] When it is necessary to continue the subsequent crack repair operation as in Example 1, Figure 1-Figure 2 、 Figure 10-12 As shown, when the secondary repair of the road surface is completed, the bucket 710 has removed the filler material overflowing within this distance. At this time, it is necessary to continue to repeat the initial filling and secondary filling operations in Example 1 and Example 2. During this process, it is necessary to start the hydraulic column 61 to retract to the maximum distance, so that the hydraulic column 61 drives the pressing plate 63 under the slide 62 to move downward and fit the crack for defoaming treatment. As the slide 62 moves downward, the connecting block 73 at the end of the slide 62 drives the connecting rod 72 to rotate around the bracket 71, so that the connecting rod 74 at the end of the connecting rod 72 drives the slide plate 75 to move upward. Since the gear 711 is fixed on the rotating shaft 77, the electric cart 1 is fixed with a tooth plate 712, and the gear 711 and the tooth plate 712 are in a state of alignment and mutual meshing. Therefore, when the rotating shaft 77 rises with the slide plate 75, when the gear 711 rises to the meshing position with the tooth plate 712, the gear 711 is forced to rotate under the influence of the meshing action of the gear 711 and the tooth plate 712. As the gear 711 rotates, the rotating shaft 77 fixed with the gear 711 also rotates synchronously, thereby causing the bucket 710 installed in the middle of the rotating shaft 77 to rotate synchronously, and the overflowed caulking material removed is poured into the collection box 713, thereby realizing the collection of the overflowed caulking material and reducing the waste of the caulking material.

[0060] During the rotation of gear 711, Figure 12As shown, since the torsion spring 79 is coaxially sleeved on the outer ring of the rotating shaft 77, and the two ends of the torsion spring 79 are fixedly connected to the inner wall of the gear 711 and the inner wall of the slide 75 respectively, when the gear 711 is meshed and rotates, it will drive the torsion spring 79 to generate torque and store force. After the overflowed caulking material is completely poured into the collection box 713, the hydraulic column 61 is started to extend a distance, so that the hydraulic column 61 drives the slide 62 to move upward. When the slide 62 moves upward, the connecting rod 72 installed on the end side of the slide 62 through the connecting block 73 rotates and is in a parallel state. The slide 75 installed on the end side of the connecting rod 72 through the connecting rod 74 moves downward. As the slide 75 continues to move downward, When the gear 711 at the end of the slide 75 is disengaged from the tooth plate 712, the gear 711 is released from its relative restriction, and the torsion spring 79 uses its own elastic force to drive the rotating shaft 77 to rotate rapidly within the slide 75, causing the bucket 710 in the middle of the rotating shaft 77 to rotate and reset. As the rotating shaft 77 continues to rotate, because the end of the rotating shaft 77 is fixed with a resistance block 78, and the end of the slide 75 is installed with a protrusion 76, and the two are on the same circumferential surface, when the resistance block 78 at the end of the rotating shaft 77 rotates to abut against the protrusion 76, the rotation of the rotating shaft 77 is mechanically limited. At this time, the bucket 710 rotates to the maximum angle, assumes a vertical posture and maintains a specific distance from the ground, and is in a standby state. When entering a new round of cleaning process, the hydraulic column 61 is restarted to fully extend it. The hydraulic transmission system drives the slide 75 to move down along the guide rail, driving the bucket 710 to descend synchronously until the blade of the bucket 710 is precisely in contact with the road surface and ready for cleaning operation.

[0061] This design forms a cyclic working mode of cleaning and storage. Through the coordinated operation of hydraulic drive and mechanical limit, it ensures that the bucket 710 automatically switches between cleaning operation and standby state, effectively improving the operating efficiency and automation level of road grouting maintenance.
