Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of traffic engineering, in particular to a traffic engineering road repairing device. BACKGROUND

[0002] Roads are prone to damage such as cracks, potholes, and surface peeling due to long-term vehicle load, natural environmental erosion (such as rain erosion and temperature changes), and other factors, and need to be repaired in time to ensure traffic safety and road service life. Currently, the mainstream road repair operation in the industry still relies on the traditional decentralized equipment and manual coordination mode;

[0003] However, the existing road repair operation requires multiple independent equipment to complete, usually needs to schedule sweeping equipment, crack identification tools, repair liquid mixing devices, and flattening equipment in sequence, and the transfer between equipment needs to rely on transport vehicles, not only occupying additional transport resources, but also needing to repeatedly adjust the equipment position at the operation site to match the repair area, the process connection takes a long time, and there are deviations in the operation range of each equipment, which is prone to problems such as the repair area not being covered by the cracks to be repaired, the repair liquid being deviated from the center of the cracks, and the like, which needs to be adjusted manually, resulting in low overall operation efficiency and high labor and time costs.

[0004] At the same time, the existing repair operation is highly dependent on manual operation, especially in the identification of the area to be repaired and the control of the equipment. Under the traditional mode, the operator needs to walk around the road surface, and through visual observation or handheld tool measurement, the position and size of the cracks and potholes can be located. This process not only takes time and effort, but also is prone to missing small cracks due to human visual error or misjudging the crack depth, resulting in improper use of repair liquid in subsequent repair. In terms of equipment movement and steering control, the existing mixing and flattening equipment often needs manual real-time adjustment of the direction through the control lever to ensure that the equipment is aligned with the area to be repaired. In particular, in the large-area road repair scene of highways, municipal trunk roads, and the like, the operator needs to maintain high concentration for a long time, which is extremely labor-intensive and is prone to equipment steering deviation due to fatigue, causing waste of repair liquid or deviation of the repair position, affecting the repair accuracy.

[0005] In addition, the existing repair equipment has obvious limitations and is difficult to ensure the stability of the repair quality and environmental adaptability. The repair liquid mixing device is usually a single cylinder structure, and the barrel is prone to bulging and deformation due to the centrifugal force of the repair liquid and its own weight during mixing, resulting in uneven gap between the stirring blade and the barrel wall, and problems such as insufficient mixing of the repair liquid and stratification of the sediment, which further affects the bonding effect of the repair liquid and the road surface. At the same time, in low-temperature environments (such as winter), the existing mixing device lacks temperature control function, and the repair liquid is prone to solidification or reduced flowability due to too low temperature, further reducing the repair quality and limiting the application scenarios of the equipment. SUMMARY

[0006] To address the aforementioned technical problems, this invention provides a road repair device for traffic engineering, which solves the problems in the prior art where road repair operations require time-consuming scheduling and coordination of multiple devices, rely on manual identification of the area to be repaired and control of the equipment, resulting in high labor intensity and poor accuracy, and suffer from unstable repair quality and poor environmental adaptability due to limitations in equipment structure.

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0032] Example: This invention provides a road repair device for traffic engineering, as shown in the attached document. Figure 1 As shown, it includes a mobile vehicle body 100 and a base plate 101;

[0033] The sweeping component 200 is located at the front end of the mobile vehicle 100 and is used to sweep the area of ​​the road surface to be repaired.

[0034] The identification control component 300 is installed on the upper part of the mobile vehicle 100 to identify the area of ​​the road surface to be repaired and to control the movement and steering of the mobile vehicle 100.

[0035] The mixing and repair component 400 is located on the upper part of the mobile vehicle body 100 and behind the identification and control component 300. It is used to mix and output repair fluid for material feeding and repair of the area to be repaired.

[0036] The flattening component 500 is located at the lower rear end of the mobile vehicle body 100 and is used to flatten the road surface in the repaired area.

[0037] As attached Figure 2 As shown, a discharge hole 102 is provided through one side of the upper end of the base plate 101. Guard plates are also provided on both sides of the base plate 101, and a front steering wheel 103 and a rear wheel 105 are installed on each side of the guard plates. The front steering wheel 103 is connected to the identification control component 300 via a control shaft 104. The front steering wheel 103 provides guidance, while the rear wheel 105 acts as the driven wheel, together completing the movement. The control shaft 104 serves as the transmission link connecting the identification control component 300 and the front steering wheel 103, converting the steering commands of the control element into the mechanical movements of the front steering wheel 103, ensuring that the equipment moves along the planned path.

[0038] As attached Figure 2 and attached Figure 3 As shown, the sweeping assembly 200 also includes an extension plate 201 fixedly disposed at the front end of the base plate 101. A protective cover 202 is installed on the upper end of the extension plate 201. A first driving member 203 is installed on one side of the upper end of the protective cover 202. An active toothed pulley 204 is fixedly installed at the output end of the first driving member 203. A first driven toothed pulley 205 and a second driven toothed pulley 206 are also disposed on the same side as the active toothed pulley 204. The active toothed pulley 204 is connected to the first driven toothed pulley 205 and the second driven toothed pulley 206 through a toothed belt 207, and rotates synchronously in the same direction. The active toothed pulley 204, the first driven toothed pulley 205, the second driven toothed pulley 206 and the toothed belt 207 are all located inside the protective shell. A sweeping brush 208 is fixedly installed at the lower end of the output shaft of the active toothed pulley 204, the first driven toothed pulley 205 and the second driven toothed pulley 206. The sweeping brush 208 is used to clean the area of ​​the road surface to be repaired. The cleaning area is moved forward by the extension plate 201 to ensure that cleaning is completed before repair. The protective cover 202 provides safety protection, preventing dust and debris from flying and protecting the internal transmission mechanism. The first driving component 203 includes, but is not limited to, a motor, which provides power to drive the active toothed pulley 204 to rotate. The active toothed pulley 204 is connected to the first driven toothed pulley 205 and the second driven toothed pulley 206 through the toothed belt 207 to achieve synchronous and unidirectional rotation, ensuring that the three sweeping brushes 208 rotate at the same speed and avoiding missed areas or repeated friction due to differences in speed. The sweeping brushes 208 directly contact the road surface and remove dust, small stones, debris and other impurities from the area to be repaired by rotation, providing a clean road surface base for subsequent repair liquid application and preventing impurities from affecting the adhesion of the repair layer.

[0039] As attachedFigure 4 As shown, the identification control component 300 also includes a control box 301 fixedly mounted on the upper end of the base plate 101. A switch 302 is provided on one side of the front end of the control box 301, and a camera 303 is installed in the middle of the front end of the control box 301. The camera 303 is used to identify the area of ​​the road surface to be repaired, and after confirming the movement path, it drives the control shaft 104 and the front steering wheel 103 to turn and move through the control element in the control box 301. The switch 302 is used to control the start and stop of the entire identification control component 300, allowing the operator to manually intervene in the operation of the equipment, facilitating emergency shutdown or work switching. The camera 303 is used to capture real-time images of the road surface conditions, identify cracks, potholes, and areas waiting to be repaired, and simultaneously record the road environment to assist in planning the equipment's movement path. The control element in the control box 301 is used to receive the image data transmitted by the camera 303, analyze it to determine the location of the area to be repaired and the movement path, and then send a command to the control shaft 104 to drive the front steering wheel 103 to turn, while coordinating the forward speed of the moving vehicle 100. This component is used to automatically identify and plan the path of the area to be repaired, and to precisely control the movement and steering of the device, ensuring that the cleaning, repairing and flattening actions can be accurately applied to the target area, avoiding operational deviations and improving repair efficiency and accuracy.

[0040] As attached Figure 5 and attached Figure 6 As shown, the mixing and repair assembly 400 includes a steel frame 401 and a support frame 402 fixedly installed on the upper part of the base plate 101. An outer cylinder 403 is fixedly installed on the inner side of the upper part of the steel frame 401. A fixed cover 404 is fixedly installed on the upper end of the outer cylinder 403. The fixed cover 404 is crescent-shaped and is installed on a movable cover 405 via a hinge. An inner cylinder 406 is also installed on the inner wall of the outer cylinder 403. A steel ring 407 is fixedly installed around the outer cylinder 403 and the inner cylinder 406. Multiple sets of steel rings 407 are provided. The steel frame 401 is used to provide stable support for the outer cylinder 403 and the inner cylinder 406 and withstand the mixing process. The weight of the inner cylinder 406 and the repair fluid is controlled to prevent the tank from shifting due to the load, ensuring stable stirring and feeding. The outer cylinder 403 serves as the outer protective shell, while the inner cylinder 406 acts as the container for stirring the repair fluid. Multiple sets of steel rings 407 between the inner and outer cylinders 406 enhance the rigidity of the tank, preventing the inner cylinder 406 from bulging or deforming due to centrifugal force during stirring or the weight of the repair fluid. They also maintain the roundness of the tank and prevent friction between the spiral blades and the tank wall. In addition, the steel rings 407 can also separate the gap between the inner and outer cylinders 403 and can be filled with media to keep the repair fluid warm during stirring, improving the temperature stability of the repair fluid.

[0041] A second driving component 408 is fixedly installed on the upper end of the fixed cover 404. A stirring shaft 409 is fixedly installed on the output end of the second driving component 408. The stirring shaft 409 is located inside the inner cavity of the inner cylinder 406, and spiral blades are provided on the outer side of the stirring shaft 409. The stirring shaft 409 is used to stir the repair liquid. The fixed cover 404 has a semi-enclosed structure to prevent the repair liquid from splashing during stirring. The movable cover 405 can be opened and closed by a hinge, which facilitates the addition of repair liquid raw materials to the inner cylinder 406 and makes operation convenient. The second driving component 408 includes, but is not limited to, a motor, which can provide power for stirring and drive the stirring shaft 409 to rotate. The spiral blades rotate with the stirring shaft 409, which can turn the repair liquid at the bottom of the inner cylinder 406 upward, realize all-round uniform stirring, avoid sedimentation and stratification of the repair liquid, and ensure that the concentration of the repair liquid is consistent.

[0042] A pipe 410 is installed at the lower end of the outer cylinder 403. The pipe 410 is placed on the support frame 402. A regulating valve 411 is installed in the middle of the pipe 410. The output end of the pipe 410 passes through the discharge hole 102 and is equipped with a nozzle 412 for discharging the repair fluid. The pipe 410 serves as a delivery channel for the repair fluid, guiding the repair fluid in the inner cylinder 406 to the road surface. The regulating valve 411 controls the flow rate of the repair fluid in the pipe 410, that is, adjusts the discharge amount according to the size of the crack to avoid waste or insufficient filling. The nozzle 412 evenly injects the repair fluid into the area to be repaired, ensuring complete coverage and dense filling of the repair fluid.

[0043] This component can uniformly mix and precisely deliver the repair fluid, filling the area to be repaired and achieving basic repair of the damaged parts of the road surface, laying the foundation for subsequent compaction work.

[0044] As attached Figure 3 As shown, the flattening assembly 500 includes a hydraulic column 501 fixedly installed at the lower rear side of the base plate 101. A pressing plate 502 is fixedly installed at the lower end of the hydraulic column 501. The pressing plate 502 is used to flatten the repaired area. The flattening assembly 500 is responsible for flattening the filled repair area to ensure the flatness of the road surface and the strength of the repair layer. The downward pressure of the pressing plate 502 can be controlled by adjusting the hydraulic pressure. At the same time, it can extend and retract vertically to control the height of the pressing plate 502, making it convenient to lift the pressing plate 502 when moving the equipment and lower it to fit the road surface during operation. The pressing plate 502 is in direct contact with the repaired road surface. The pressure applied by the hydraulic column 501 compacts and flattens the repair fluid, eliminating the height difference between the repaired area and the original road surface, ensuring the flatness of the road surface. At the same time, compaction can enhance the bonding strength between the repair fluid and the original road surface, preventing depressions or loosening later.

[0045] This component is used to compact and flatten the area filled with repair fluid, ensuring that the smoothness of the repaired road surface meets traffic engineering requirements, while improving the density and durability of the repair layer and extending the service life of the repaired road surface.

[0046] As can be seen from the above, the overall device achieves automation and precision in road repair through a streamlined process of identification and positioning, sweeping, mixing and dispensing, and compaction. It eliminates the need for separately deploying scattered equipment such as sweepers, mixing devices, and compactors, reducing equipment transfer and process connection time. The identification and control component 300 automatically locates the area to be repaired and plans the path, eliminating the need for manual inspection of cracks and manual adjustment of equipment positions, significantly reducing labor intensity, especially suitable for large-area road repair scenarios. The sweeping component 200 removes impurities through synchronous rotation of the brushes 208, preventing stratification and detachment caused by the mixing of repair fluid with dust and gravel. The compaction component 500 uses hydraulic pressure adjustment to ensure dense filling of the repair fluid, eliminating the height difference with the original road surface and ensuring flatness. In the mixing and repair component 400, spiral blades ensure uniform mixing of the repair fluid, the regulating valve 411 and nozzle 412 precisely control the dispensing amount, and the steel ring 407 maintains mixing stability and prevents uneven mixing caused by barrel deformation, ensuring the performance of the repair fluid throughout the entire process from raw materials to construction. Meanwhile, the steel ring 407 of the stirring repair component 400 can separate the gap between the inner and outer cylinders 403, fill the gap with insulation medium, and prevent the repair liquid from solidifying.
