Description

Technical Field

[0001] The present invention relates to the technical field of road load monitoring, and in particular to a road maintenance management load real-time monitoring system and method. Background Art

[0002] The traffic load of the road affects the life of the road surface and the structural safety of the bridge. The existing method of monitoring vehicle load is generally to bury vehicle dynamic weighing equipment under the road surface to monitor the axle weight and total weight of passing vehicles. The operators tie several dynamic asphalt strain gauges (ASG) to two wooden sticks, level them based on their own experience, and then spread asphalt. This method of burying dynamic asphalt strain gauges (ASG) relies entirely on skilled operators. It is extremely difficult for novices to operate, and it is impossible to level the dynamic asphalt strain gauges (ASG) or even ensure that multiple dynamic asphalt strain gauges (ASG) are in the same measuring point.

[0003] The existing announcement number CN215811181U discloses a real-time load monitoring system for road maintenance management, including a placement frame, two dynamic asphalt strain gauges arranged on the front and back of the placement frame in radial center symmetry, and an auxiliary placement mechanism is provided at the lower end of the placement frame. The auxiliary placement mechanism includes an auxiliary support component arranged between the placement frames for supporting the placement frames and an auxiliary positioning component arranged at the lower end of the placement frame for positioning the entire placement frame. By placing the dynamic asphalt strain gauge on both sides of the placement frame, the dynamic asphalt strain gauge can be leveled by simply adjusting the level of the placement frame, which solves the problem of traditional difficulty in leveling the dynamic asphalt strain gauge by tying it to a wooden stick or steel bar. At the same time, the entire placement frame can also adjust the height to adapt to the paving of road surfaces of different heights.

[0004] However, the above-mentioned real-time load monitoring system for road maintenance management only installs the dynamic asphalt strain gauge through two placement frames, which may lead to insufficient stability of the support for the dynamic asphalt strain gauge and affect the measurement effect. Summary of the invention

[0010] Wherein, the base has a limiting groove, and the limiting groove is located on a side of the base close to the pull rod.

[0011] Among them, the leveling component also includes a threaded rod, an adjusting sleeve and a supporting platform. The number of the threaded rods is three. The three threaded rods are respectively fixedly connected to the base and distributed in a circle.

Figure 2 The present invention Figure 1 Enlarged view of point A. Figure 3 It is a cross-sectional view of the road maintenance management load real-time monitoring system according to the first embodiment of the present invention. The present invention provides a real-time monitoring system for road maintenance and management loads: comprising a dynamic asphalt strain gauge 101, a leveling component, an adjustment component and an installation component, wherein the installation component comprises a top plate 102, a support plate 103, a reinforcement plate 104 and a mounting block 105, the leveling component comprises a base 106, an abutment plate 107, a pointed head 108, a pull rod 109, an abutment spring 110, a threaded rod 112, an adjustment sleeve 113 and a support platform 114, the base 106 has a limiting groove 111, the adjustment component comprises a first slider 115, a first rod 116, a second slider 117, a second rod 118, a connecting rod 119, an adjustment block 120, an adjustment screw 121 and a handle 122, and the above-mentioned scheme solves the problem that the existing real-time monitoring system for road maintenance and management loads only installs the dynamic asphalt strain gauge 101 through two placement racks, which may lead to insufficient stability of supporting the dynamic asphalt strain gauge 101 and affect the measurement effect. It can be understood that the above-mentioned scheme can also be used to solve the problem of height adjustment.

[0030] For this specific embodiment, the adjustment component is located above the leveling component, the top plate 102 is connected to the adjustment component, the support plate 103 is fixedly connected to the top plate 102 and is located on the top of the top plate 102, one side of the reinforcement plate 104 is fixedly connected to the support plate 103, and the other side is fixedly connected to the top plate 102, the number of the dynamic asphalt strain gauges 101 is two, the two dynamic asphalt strain gauges 101 are respectively located on the front and back of the support plate 103, and are radially symmetrically arranged, and both ends are respectively connected to the reinforcement plate 104, the mounting block 105 is detachably connected to the support plate 103, and allows the dynamic asphalt strain gauge 101 to pass through. The leveling component is placed on the road surface to be tested and has a leveling function. The adjustment component is arranged on the top. The adjustment component has a height adjustment function and supports the top plate 102. The support plate 103 is fixed on the top of the top plate 102. The reinforcing plates 104 are arranged on both sides of the support plate 103. The reinforcing plates 104 enhance the structural strength of the connection between the support plate 103 and the top plate 102. The dynamic asphalt strain gauge 101 is used to monitor the road load conditions. After passing through the mounting block 105, both ends are installed on the reinforcing plates 104, and then the mounting plate is fixed on the support plate 103, and then the dynamic asphalt strain gauge 101 is supported by multiple supporting points, which makes the installation stable and is beneficial to the accuracy of the measurement.

[0031] The base 106 is located below the top plate 102, the abutting plate 107 is located inside the base 106, and there are multiple prongs 108, which are respectively fixedly connected to the abutting plate 107 and located at the bottom of the abutting plate 107. Multiple abutting springs 110 are arranged between the abutting plate 107 and the base 106, and the pull rod 109 is slidably connected to the abutting plate 107 and extends out of the base 106. The limiting groove 111 is located on a side of the base 106 close to the pull rod 109. When the pull rod 109 slides into the limiting groove 111, the abutment plate moves up, driving the pointed head 108 to be hidden inside the base 106. At this time, the base 106 is used for support, which is suitable for flat roads. For uneven roads, the pull rod 109 is slid to move out of the limiting groove 111 and then into the sliding channel of the base 106. At this time, the elastic force of the abutment spring 110 pushes the abutment plate 107 downward, driving the pointed head 108 to be inserted into the ground, so that the base 106 is installed firmly.

[0032] Secondly, there are three threaded rods 112, which are respectively fixedly connected to the base 106 and distributed in a circle. The adjusting sleeve 113 is threadedly connected to each threaded rod 112, and the supporting platform 114 is arranged on the top of the adjusting sleeve 113. After the base 106 is stably installed, a level is placed on the supporting platform 114, and then the adjusting sleeve 113 is rotated. The adjusting sleeve 113 is rotatably arranged below the supporting platform 114 and is threadedly matched with the threaded rod 112. The height of the adjusting sleeve 113 is adjusted by forward or reverse rotation, thereby balancing the supporting platform 114.

[0033] At the same time, the two ends of the first rod 116 are rotatably connected to the first slider 115 and the top plate 102, the two ends of the second rod 118 are rotatably connected to the second slider 117 and the top plate 102, the first slider 115 and the second slider 117 are slidably connected to the support platform 114, and the first rod 116 and the second rod 118 are cross-distributed. There are two first sliders 115 and two second sliders 117, respectively, and they are arranged oppositely. The connecting rod 119 is fixedly connected between the two first sliders 115 and the two second sliders 117, and the adjusting blocks 120 are fixed to the two connecting rods 119. The adjusting screw 121 passes through the two adjusting blocks 120, and the handle 122 is detachably connected to the adjusting screw 121. The first slider 115 and the first rod 116, as well as the second slider 117 and the second rod 118 are respectively two groups and are arranged opposite to each other to enhance the strength of the supporting structure. The connecting rod 119 connects the two first sliders 115 and the two second sliders 117. The adjusting block 120 is fixed on the connecting rod 119, and the two adjusting blocks 120 are arranged opposite to each other. The adjusting screw 121 passes through the two adjusting blocks 120. The adjusting screw 121 is a positive and negative thread screw, which drives the two adjusting blocks 120 to move toward or oppositely by rotation, or the internal threads of the two adjusting blocks 120 are arranged oppositely, and then move toward or oppositely following the rotation of the adjusting screw 121. The handle 122 is inserted into one end of the adjusting screw 121 to facilitate manual rotation of the adjusting screw 121. It is convenient to disassemble when adjustment is no longer needed, saving costs.

[0034] A real-time monitoring system for road maintenance and management loads according to the present embodiment is used, and the base 106 is placed on the road to be monitored. The leveling assembly is adjusted according to the flatness of the road surface. If the road is flat, the pull rod 109 is slid into the limit groove 111 so that the pointed head 108 is hidden inside the base 106. If the road is uneven, the pull rod 109 is slid out of the limit groove 111, and the elastic force of the abutment spring 110 is used to push the abutment plate 107 and the pointed head 108 into the ground to ensure that the base 106 is stable. A level is placed on the support platform 114, and the height of the adjustment sleeve 113 is adjusted by rotating the adjustment sleeve 113 so that the support platform 114 reaches a horizontal state. The lead screw 121 and the adjustment block 120 adjust the positions of the first slider 115 and the second slider 117, thereby adjusting the height and stability of the top plate 102. The support plate 103 is installed on the top plate 102, and the support plate 103 is fixedly connected to the top plate 102 through the reinforcement plate 104. The dynamic asphalt strain gauge 101 is passed through the mounting block 105 and both ends are mounted on the reinforcement plate 104. The mounting block 105 is fixed on the support plate 103 to ensure that the dynamic asphalt strain gauge 101 is stably installed. The dynamic asphalt strain gauge 101 is started to start real-time monitoring of road load conditions, and the monitoring data is transmitted to the data center or related monitoring platform in real time for analysis and processing.

[0035] By using the leveling assembly and the adjustment assembly in coordination, the system can be stably installed on uneven roads. The design of the pointed head 108 and the abutment spring 110 can adapt to the conditions of different road surfaces and provide additional supporting force. The dynamic asphalt strain gauge 101 is fixed by multiple supporting points, which improves the stability and accuracy of the measurement. The design of the reinforcing plate 104 enhances the structural strength between the support plate 103 and the top plate 102, further improving the measurement accuracy. The design of the adjustment assembly allows height adjustment as needed to adapt to the height requirements of different roads. The use of the adjustment screw 121 and the adjustment block 120 makes height adjustment more convenient and precise. The design of the handle 122 makes the rotation of the adjustment screw 121 more labor-saving and also facilitates disassembly when not needed.

[0036] The second embodiment of the present application is:

[0037] Based on the first embodiment, please refer to Figure 4 ,in, Figure 4 1 is a flowchart of the steps of a real-time monitoring method for road maintenance management load according to the second embodiment of the present invention. A real-time monitoring method for road maintenance management load according to this embodiment includes the following steps:

[0038] S201: placing the base 106 on the road surface to be monitored. If the road surface is uneven, lowering the support plate 107 and the pointed head 108 to keep the base 106 stable;

[0039] S202: Rotate the adjusting sleeve 113 to level the supporting platform 114;

[0040] S203: After leveling, the handle 122 is turned to drive the adjusting screw 121 to adjust the distance between the first slider 115 and the second slider 117, and then the angle between the first rod 116 and the second rod 118 is adjusted to drive the top plate 102 to rise and fall, so that it is suitable for monitoring roads at different heights;

[0041] S204: Install both ends of the dynamic asphalt strain gauge 101 on the reinforcing plate 104. At this time, the dynamic asphalt strain gauge 101 passes through the mounting block 105, and then the mounting block 105 is installed on the supporting plate 103;

[0042] S205: After the installation is completed, the overall structure is buried, and then the dynamic asphalt strain gauge 101 is started to monitor the road load in real time, and the monitoring data is transmitted to the data center or related monitoring platform in real time;

[0043] S206: Analyze the monitoring data in real time and issue a warning or alarm signal in a timely manner based on the analysis results.

[0044] Specifically, the base 106 is placed on the surface of the road to be monitored. According to the flatness of the road surface, it is decided whether to lower the abutment plate 107 and the pointed head 108 to keep the base 106 stable. The adjusting sleeve 113 is rotated to adjust the height of the supporting platform 114 to ensure that the supporting platform 114 is level. The handle 122 is rotated to drive the adjusting screw 121 to rotate. The movement of the adjusting screw 121 changes the distance between the first slider 115 and the second slider 117, thereby adjusting the angle between the first rod 116 and the second rod 118. The change in the angle drives the top plate 102 to rise and fall, so that it can adapt to different heights. Monitor the road, install both ends of the dynamic asphalt strain gauge 101 on the reinforcing plate 104, ensure that the dynamic asphalt strain gauge 101 passes through the mounting block 105, fix the mounting block 105 on the supporting plate 103, complete the installation of the dynamic asphalt strain gauge 101, bury the overall structure to ensure the stability and safety of the system, start the dynamic asphalt strain gauge 101, start real-time monitoring of road load conditions, transmit the monitoring data to the data center or related monitoring platform in real time, analyze the monitoring data in real time, evaluate the road load conditions, and issue early warning or alarm signals in time according to the analysis results so as to take corresponding maintenance measures.

[0045] The system can be adjusted according to the flatness of different road surfaces to ensure that the base 106 is stable. Through the cooperation of the adjusting screw 121 and the slider, the system can adapt to monitoring roads at different heights. The dynamic asphalt strain gauge 101 is fixed by the reinforcing plate 104, which improves the stability and accuracy of the measurement. The real-time monitoring function can detect abnormal road loads in time and provide strong support for road maintenance. The installation, adjustment and startup process of the system is relatively simple, which reduces the difficulty of operation. The design of the handle 122 makes the rotation of the adjusting screw 121 more labor-saving and improves work efficiency. The real-time monitoring and data analysis functions can detect abnormal road loads in time and issue early warning or alarm signals, which helps to detect and deal with road problems in time and reduce road maintenance costs and safety risks.
