Description

Technical Field

[0001] This application relates to the field of road maintenance, and in particular, to a road maintenance device. Background Art

[0002] Road cracks, as the initial manifestation of road diseases and also the most common road diseases, occupy a major position in road disease detection. There are many reasons for the cracking of highway asphalt pavements. The main reasons for the generation of cracks are the action of traffic loads and the temperature change of the asphalt surface layer. Structural damage cracks are caused by the action of traffic loads. Under the action of wheel loads, when the tensile stress generated at the bottom of the road structure layer is greater than the tensile strength of its material, structural damage cracks will occur on the road surface. Temperature cracks are caused by the temperature change of the asphalt surface layer, including low-temperature shrinkage cracks and temperature fatigue cracks.

[0003] Generally, when cracks appear on asphalt pavements, they need to be repaired in time. Otherwise, the cracks will continue to deteriorate and form potholes. To keep the asphalt pavement in good condition and ensure a series of management and engineering activities for its safe and smooth operation, road maintenance equipment is required to regularly maintain the road surface; the maintenance types include but are not limited to preventive maintenance, routine maintenance, emergency maintenance, periodic overhaul or road expansion and reconstruction, etc.; for this reason, there are various types of highway pavement maintenance equipment.

[0004] The existing road crack maintenance operations lack the support of road maintenance detection data. Relying on manual inspections has problems such as high blindness, easy omission, low efficiency, high intensity, untimely discovery, and high safety risks. When specifically constructing, manually searching for cracks cannot accurately and comprehensively detect and locate road cracks, and it is easy to overlook some small cracks, posing a risk of further expansion of small cracks. Frequent road maintenance operations seriously affect the normal operation order of road traffic. At the same time, the existing road crack repairs require the cooperation of multiple equipment such as a crack sealer, a crack expander, and a dust cleaning device during construction. The process is cumbersome, the construction period is long, it occupies a large amount of manpower and material resources, and long-term road occupation during construction seriously affects road traffic and there are certain hidden safety hazards in maintenance construction. In addition, most of the existing crack sealers adopt a trolley structure. The road cracks are long, narrow, and tortuous, and the trolley structure is relatively large and cannot turn flexibly along with the cracks. The crack repair agent sprayed by the nozzle is often sprayed on the road surface and cannot be accurately sprayed into the cracks, affecting the maintenance quality and construction efficiency. Summary of the Invention

[0005] In order to improve the road maintenance quality and construction efficiency, this application provides a road maintenance device.

[0006] The road maintenance device provided by this application adopts the following technical solutions: A road maintenance device, comprising: The main body of the device, the main body of the device includes a vehicle body and rollers arranged below the vehicle body, and the rollers are driven forward by a first driving member arranged on the vehicle body; A crack detection system, the crack detection system is arranged below the front end of the vehicle body, detects road surface cracks, and locates the road surface cracks; A repair agent spraying system, the repair agent spraying system is arranged at the middle position of the vehicle body, includes a repair agent storage tank, a nozzle, and a discharge pipe with one end connected to the repair agent storage tank and the other end connected to the nozzle. A pumping pump is arranged at the bottom of the repair agent storage tank to pump the repair agent out of the repair agent storage tank. An adjusting device is arranged at the nozzle, and the adjusting device adjusts the position and direction of the nozzle; A control system, the control system is arranged above the vehicle body, includes a control member, the control member is electrically connected to the crack detection system, the repair agent spraying system, and the first driving member. The crack detection system sends crack data to the control member, and the control member makes a judgment according to the received data and controls the repair agent spraying system to spray.

[0007] By adopting the above technical solutions, when repairing the road surface, first, the crack detection system automatically detects cracks during the driving of the device, and can accurately identify and locate the cracks on the road surface. Then, the detailed information data such as the position and depth of the detected cracks is transmitted to the control member of the control system. The control member analyzes the data, and according to the analysis result, through the adjusting device of the control repair agent spraying system, the nozzle can flexibly adjust the position and spraying direction according to the actual situation of the cracks, ensuring that the repair agent can evenly and accurately cover the cracks, improving the repair quality. At the same time, the control member also controls the first driving member to adjust the driving speed of the device. The speed is slower during repair and faster after repair. This method not only improves the operation convenience, but also ensures the accuracy and timeliness of the repair. The precise crack positioning and repair agent spraying reduce the waste of the repair agent, meet the requirements of environmental protection and energy conservation, and improve the road maintenance quality and construction efficiency.

[0008] Preferably, the crack detection system includes a high-definition camera and an image processing unit. The high-definition camera is arranged at the front end of the vehicle body to capture road surface images in real time. The image processing unit is electrically connected to the high-definition camera, receives the images transmitted in the high-definition camera, and identifies the specific situation of the road surface cracks through the internal recognition system, and then sends the identified crack data to the control system to realize the automatic detection and accurate positioning of the cracks.

[0009] By adopting the above technical solution, by utilizing the high resolution of the high-definition camera and the powerful processing ability of the image processing unit, cracks on the road surface can be accurately captured and identified, providing accurate position information for subsequent repair work, facilitating the control system to accurately spray the repair agent onto the crack position, improving the repair efficiency, and reducing the waste of the repair agent.

[0010] Preferably, two of the high-definition cameras are included and are respectively arranged on both sides of the front end of the vehicle body.

[0011] By adopting the above technical solution, by arranging two high-definition cameras on both sides of the front end of the vehicle body, a binocular stereo vision system can be formed. In this way, the device can not only capture planar images, but also calculate the depth information of the photographed object through the parallax of the two cameras, providing more accurate three-dimensional data for subsequent crack detection and positioning, facilitating the subsequent control component to more accurately repair the crack with the nozzle, improving the repair effect, and further improving the repair efficiency.

[0012] Preferably, the high-definition camera is detachably connected to the vehicle body.

[0013] By adopting the above technical solution, setting the high-definition camera to be detachably connected to the vehicle body enables maintenance personnel to easily remove the camera for inspection, repair, or cleaning if the camera malfunctions or needs to be cleaned, improving the maintenance efficiency and reducing the maintenance cost.

[0014] Preferably, the adjusting device includes a lateral moving member and a steering member. The lateral moving member includes a slide rail arranged under the vehicle body and a slider slidably connected to the slide rail. The slide rail is horizontally arranged along the middle position of the vehicle body. The slider is driven by a second driving member arranged at the end of the slide rail, and the nozzle moves horizontally under the vehicle body through the slider; The steering member includes a rotating base rotatably connected to the slider and a pitching member arranged on the rotating base. The rotating base is driven by a third driving member arranged on the slider to rotate along its own axis. The pitching member includes a support member fixed at one end to the rotating base and a fourth driving member. The nozzle is rotatably connected to the support member, and the fourth driving member drives the nozzle to rotate along the rotating shaft.

[0015] By adopting the above technical solution, when detecting the road surface by the device, the crack position is not fixed and the position to be repaired is uncertain. Through the combination of the slide rail and the slider, the nozzle can achieve precise lateral movement under the vehicle body, and through the steering member, the nozzle can be accurately aligned with the crack, enabling it to adapt to the operation requirements of different angles, thereby improving the maintenance efficiency.

[0016] Preferably, a displacement sensor is provided at the slider, and an angle sensor is provided at the steering member. The displacement sensor, the angle sensor, the second driving member, the third driving member, and the fourth driving member are all electrically connected to the control member.

[0017] By adopting the above technical solution, the displacement sensor, the angle sensor, the second, third, and fourth driving members are electrically connected to the control member. During use, the control member controls the second, third, and fourth driving members to drive the nozzle to move to any desired position. At the same time, the specific movement information of the nozzle is transmitted to the control member through the displacement sensor and the angle sensor, so that the position of the nozzle can be accurately controlled, and the nozzle can be adjusted more efficiently, thereby improving the repair efficiency.

[0018] Preferably, the discharge pipe is a flexible pipe, and an intermediate member is provided at the connection between the discharge pipe and the nozzle. One end of the intermediate member is fixedly connected to the discharge pipe, and the other end is rotatably connected to the nozzle.

[0019] By adopting the above technical solution, when adjusting the injection position of the repair agent by moving the position of the nozzle, the discharge pipe connected to the nozzle moves accordingly when the nozzle moves. The discharge pipe is set as a flexible pipe to facilitate the movement of the nozzle. At the same time, an intermediate member is provided at the connection between the discharge pipe and the nozzle, so that the discharge pipe does not rotate with the nozzle when the nozzle rotates, preventing the discharge pipe from folding together when rotating and being unable to discharge the repair agent, which affects the repair effect.

[0020] Preferably, a navigation system is further included. The navigation system is provided on the equipment main body to plan the driving route of the equipment and record the positions of the cracks that have been repaired.

[0021] By adopting the above technical solution, a navigation system is provided on the equipment main body. The navigation system can intelligently plan the optimal driving route according to the requirements of the repair task and the actual situation of the road surface, which helps the equipment to traverse the road surface area to be repaired more efficiently, reduce unnecessary driving and time consumption, thereby improving work efficiency. At the same time, the navigation system can accurately record the positions of the cracks that have been repaired, forming a detailed repair record database, which can not only track the progress and effect of the repair work, but also provide valuable data support for subsequent maintenance and management. Again, because the vehicle focuses on different positions on the road surface and different road surfaces need to be maintained at different frequencies, based on the data of the navigation system, the manager can more reasonably allocate and schedule resources, such as repair materials, human resources, etc., to ensure the efficient progress of the repair work.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. When repairing the road surface, first, the crack detection system automatically detects cracks during the operation of the equipment, enabling accurate identification and positioning of the cracks on the road surface. Then, detailed information data such as the detected crack positions and depths are transmitted to the control component of the control system. The control component analyzes the data and, based on the analysis results, adjusts the regulating device of the repair agent spraying system through the control component, enabling the nozzle to flexibly adjust its position and spraying direction according to the actual situation of the cracks, ensuring that the repair agent can evenly and accurately cover the cracks, improving the repair quality. At the same time, the control component also controls the first driving component to adjust the driving speed of the equipment. The speed is slower during repair and faster after repair is completed. This method not only improves the operation convenience but also ensures the accuracy and timeliness of repair. Precise crack positioning and repair agent spraying reduce the waste of repair agent, meet the requirements of environmental protection and energy conservation, and improve the road maintenance quality and construction efficiency; 2. A navigation system is set on the equipment main body. The navigation system can intelligently plan the optimal driving route according to the requirements of the repair task and the actual situation of the road surface, helping the equipment to more efficiently traverse the road surface areas that need to be repaired, reducing unnecessary driving and time consumption, thereby improving the work efficiency. At the same time, the navigation system can accurately record the positions of the repaired cracks, forming a detailed repair record database, which can not only track the progress and effect of the repair work but also provide valuable data support for subsequent maintenance and management. Moreover, because the vehicle on the road surface has different focus positions and different road surfaces need different maintenance frequencies, based on the data of the navigation system, the manager can more reasonably allocate and schedule resources, such as repair materials, human resources, etc., to ensure the efficient progress of the repair work.

At the same time, to obtain more accurate crack information, two high-definition cameras 21 are set in this embodiment, respectively located on both sides of the front end of the vehicle body 11, forming a binocular stereo vision system. In this way, the device can not only capture planar images but also calculate the depth information of the photographed object, providing more accurate three-dimensional data for subsequent crack positioning and repair.

[0030] The image processing unit 22 is responsible for receiving and processing the images captured by the high-definition camera 21. It integrates advanced recognition algorithms inside and can quickly and accurately identify cracks on the pavement and send information such as the position, length, and width of the cracks to the control system 4.

[0031] The repair agent spraying system 3 is set at the middle position of the vehicle body 11 and includes a repair agent storage tank 31, a nozzle 32, and a discharge pipe 33. The repair agent storage tank 31 is made of stainless steel, having good corrosion resistance and sealing performance to ensure the quality of the repair agent. The nozzle 32 is made of wear-resistant ceramic materials and can spray the repair agent stably for a long time. The discharge pipe 33 connects the repair agent storage tank 31 and the nozzle 32 and is made of a high-pressure-resistant hose material. A middleware is set at the connection position. One end of the middleware is fixedly connected to the end of the discharge pipe 33, and the other end is rotatably connected to the nozzle 32 to ensure that the repair agent can be smoothly delivered to the nozzle 32.

[0032] An adjusting device 34 is also provided at the nozzle 32 for adjusting the position and spraying direction of the nozzle 32. The adjusting device 34 includes a lateral moving member 341 and a steering member 342. The lateral moving member 341 is composed of a slide rail 3411 and a slider 3412. The slide rail 3411 is horizontally arranged along the middle position of the vehicle body 11 and can be specifically set in the form of a slide bar. The slider 3412 is sleeved on the slide bar and is driven by a second driving member 3413 to move on the slide rail 3411, thereby driving the nozzle 32 to move horizontally under the vehicle body 11. The second driving member 3413 is set as a screw driven by a motor. The screw is arranged parallel to the slide rail 3411. A threaded hole for the screw to pass through is opened on the slider 3412, and the rotation of the screw drives the slider 3412 to move along the length direction of the slide rail 3411.

[0033] The steering member 342 includes a rotating base 3421 and a pitching member 3422. The rotating base 3421 is driven to rotate by a third driving member 34211 to achieve the horizontal rotation of the nozzle 32. The third driving member 34211 is set as a motor, and the motor is arranged inside the slider 3412. The output shaft is fixedly connected to the rotating base 3421 to drive the rotating base 3421 to rotate; The pitching member 3422 is composed of a support member 34221 and a fourth driving member 34222. The nozzle 32 is rotatably connected to the rotating base 3421 through the support member 34221 and is driven by the fourth driving member 34222 to adjust the pitching angle. Specifically, the support member 34221 is set as a U-shaped frame, the bottom of which is fixedly connected to the rotating base 3421. The nozzle 32 is arranged in the middle of the two side surfaces of the U-shaped frame and is rotatably connected to the two end portions. The fourth driving member 34222 is set as a cylinder with the end of the output shaft hinged to the nozzle 32 and the other end hinged to the rotating base 3421. Through these adjusting devices 34, the nozzle 32 can accurately align with the crack and evenly and accurately spray the repair agent onto the crack.

[0034] The control system 4 is arranged above the vehicle body 11 and includes a control member 41 and related circuit elements. The control member 41 is electrically connected to the crack detection system 2, the repair agent spraying system 3, and the first driving member 13 to realize the reception, processing, and sending of control instructions for data. When the crack detection system 2 detects a crack, it sends the crack data to the control system 4. The control system 4 analyzes and processes the received data and controls the repair agent spraying system 3 to spray according to the analysis result. At the same time, the control system 4 also adjusts the driving speed of the equipment according to the situation of the crack to ensure the repair quality and efficiency.

[0035] A displacement sensor is provided at the slider 3412, and an angle sensor is provided at the steering member 342. The displacement sensor, the angle sensor, the second, third, and fourth driving members 34222 are electrically connected to the control member 41. During use, the control member 41 controls the second, third, and fourth driving members 34222 to drive the spray head 32 to any desired position. At the same time, the specific movement information of the spray head 32 is transmitted to the control member 41 through the displacement sensor and the angle sensor, so that the position of the spray head 32 can be accurately controlled, and the spray head 32 can be adjusted more efficiently, thereby improving the repair efficiency.

[0036] This device also includes a navigation system for planning the driving route of the device and recording the positions of the cracks that have been repaired. The navigation system uses high-precision GPS positioning technology or Beidou positioning technology and geographic information system (GIS), which can accurately locate the current position and driving trajectory of the device and record the positions of the cracks that have been repaired for subsequent inspection and maintenance.

[0037] The implementation principle of a pavement maintenance device according to an embodiment of the present application is as follows: When repairing a pavement, first, the crack detection system 2 automatically detects cracks during the driving process of the device, and can accurately identify and locate the cracks on the pavement. Then, the detailed information data such as the detected crack position and depth is transmitted into the control member 41 of the control system 4. The control member 41 analyzes the data and, according to the analysis result, through the adjustment device 34 of the repair agent spraying system 3, enables the spray head 32 to flexibly adjust its position and spraying direction according to the actual situation of the crack, ensuring that the repair agent can evenly and accurately cover the crack, improving the repair quality. At the same time, the control member 41 also controls the first driving member 13 to adjust the driving speed of the device. The speed is slower during repair and faster after repair is completed. This method not only improves the operation convenience but also ensures the accuracy and timeliness of the repair. The precise crack positioning and repair agent spraying reduce the waste of the repair agent, meet the requirements of environmental protection and energy conservation, and improve the road maintenance quality and construction efficiency.
