Technical Field

[0001] This utility model relates to the field of bridge monitoring technology, specifically to an integrated device for multi-dimensional health monitoring of bridges. Background Technology

[0002] With the rapid development of the country, people's living standards are improving in tandem. Highway transportation infrastructure plays an increasingly important role in the national economy. To develop the economy and improve people's travel conditions, countries and regions are constructing more and more highways and bridges in cities and rural areas. Bridge bearings, as key components that transfer loads and accommodate displacement between the bridge superstructure and piers, play a vital role in bridges and are an indispensable part of bridge engineering. During use, bridge bearings can develop various defects, such as voids, slippage, and aging. These defects affect the bearing's functionality. If defective bearings are not detected, repaired, or replaced in time, they may lead to serious bridge safety accidents, posing a huge threat to national and public safety. Therefore, timely detection, maintenance, and replacement of defective bearings are effective measures to ensure their functionality. Intelligent bridge bearings combine the advantages of remote monitoring, timely detection, intelligent judgment, and early warning, representing the future development direction of bridge bearings.

[0003] Chinese Patent CN217132260U discloses a replaceable multi-dimensional intelligent monitoring device for bridge bearings, including a rubber ring and monitoring sensors. The inner ring of the rubber ring matches the bridge bearing, and the rubber ring is fitted onto the outer surface of the bridge bearing. At least four sets of monitoring sensors are evenly distributed around the bridge bearing inside the rubber ring. Each set of monitoring sensors consists of horizontally arranged sensors and vertically arranged sensors. This invention, by setting a rubber ring around the periphery of the plate bearing and placing the monitoring sensors within the rubber ring, measures the vertical and horizontal displacements of the rubber. Through data acquisition, data transmission, and data processing, the vertical and horizontal loads of the plate bearing are obtained, enabling real-time monitoring of the bearing and providing data for bearing health monitoring.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: because the rubber ring is an integral structure, it is difficult to install the rubber ring to the bridge bearing, which affects construction efficiency and makes it difficult to disassemble and maintain the rubber ring later.

[0005] Therefore, we propose an integrated device for multi-dimensional health monitoring of bridges. Utility Model Content

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a method with the following beneficial effects: 1. This utility model separates the rubber ring into two U-shaped rubber bodies and connects them with a connecting component. During installation, the two U-shaped rubber bodies can be slipped onto the bridge support from both sides and then connected and fixed using the connecting component. This reduces the difficulty of operation, improves construction efficiency, and facilitates the disassembly and maintenance of the rubber ring in the later stages.

[0016] 2. By setting up a connecting component, when connecting two U-shaped rubber bodies, the T-shaped block of the second connecting block can slide into the T-shaped groove of the first connecting block. Then, simply operate the driving component to make the driving component drive the screw to rotate, and the screw drives the slider to slide along the limit rod, so that the slider drives the locking block to insert into the locking groove, thereby quickly connecting the two U-shaped rubber bodies and facilitating the connection and disassembly of the two U-shaped rubber bodies.

[0021] Support: As a crucial component for transferring loads and accommodating displacements between the bridge superstructure and piers, bridge bearings play a vital role and are an indispensable part of bridge engineering. During use, bearings can develop various defects, such as voiding, slippage, and aging. These defects affect the bearing's functionality, and failure to detect, repair, or replace damaged bearings in a timely manner can lead to serious bridge safety accidents, posing a significant threat to national and public safety and property. Therefore, timely detection, maintenance, and replacement of damaged bearings are effective measures to ensure their functionality. Intelligent bearings, combining advantages such as remote monitoring, timely detection, intelligent judgment, and early warning, represent the future development direction for bridge bearings.

[0022] In terms of structural stress monitoring, high-precision stress sensors are deployed at key parts of the bridge to capture stress changes within the structure in real time, accurately sensing the stress state of the bridge under external forces such as vehicle loads and wind. Deformation monitoring utilizes advanced technologies such as laser ranging and tilt sensors to continuously track the bridge's displacement, settlement, and tilt, promptly detecting potential deformation anomalies.

[0023] Vibration monitoring is also a crucial aspect. The device employs highly sensitive accelerometers to comprehensively record parameters such as vibration frequency and amplitude of the bridge under different operating conditions, thereby assessing the bridge's dynamic characteristics and structural stability. Simultaneously, the environmental monitoring module collects real-time information on the temperature, humidity, wind speed, and rainfall of the bridge's surrounding environment, analyzing the impact of environmental factors on the bridge structure.

[0024] This device boasts a high degree of integration, combining various monitoring equipment and data acquisition systems into one unit. This reduces compatibility issues between devices and improves the accuracy and reliability of monitoring data. Through the data transmission module, monitoring data can be transmitted to the remote monitoring center in real time and stably. At the monitoring center, professional analysis software performs in-depth mining and intelligent analysis of massive amounts of data. Once abnormal data is detected, the system immediately issues an alert, reminding management personnel to take timely measures.

[0025] The application of this integrated multi-dimensional health monitoring device for bridges enables comprehensive, real-time dynamic monitoring of bridge structures, providing a scientific basis for bridge maintenance decisions and effectively ensuring the long-term safe operation of bridges.

[0026] Traditional sensor technology is relatively outdated and lacks the accuracy to measure minute deformations and subtle changes in stress in bridges, making it difficult to accurately detect early damage and potential safety hazards in bridge structures. For example, it may not be able to detect the minute expansion of bridge cracks in a timely and accurate manner.

[0027] Traditional monitoring devices often have deficiencies or shortcomings in certain key dimensions. For example, they are not detailed enough in monitoring the dynamic response of bridges in complex environments, or they lack monitoring of special situations such as bridge foundation scour.

[0028] This utility model provides a technical solution: Please see Figures 1-4 A multi-dimensional health monitoring integrated device for bridges includes a rubber ring 2 fitted outside a bridge bearing 1 and multiple monitoring sensors 3 installed inside the rubber ring 2. The rubber ring 2 and monitoring sensors 3 are arranged in at least four groups, each group consisting of horizontally arranged and vertically arranged monitoring sensors 3. The monitoring sensors 3 employ fiber optic grating sensors. When the bridge bearing 1 changes, the rubber ring 2 will displace accordingly. The monitoring sensors 3 monitor the spatial distribution of vertical loads. By monitoring and utilizing the spatial distribution of vertical loads, bearing slippage and other defects can be detected. Based on the cumulative horizontal displacement and the total life displacement of the bearing, the remaining life of the bearing can be estimated. Specific monitoring methods have been fully disclosed in prior art CN217132260U and will not be elaborated upon here.

[0029] Specifically, the rubber ring 2 includes two U-shaped rubber bodies 21 and a connecting component 22 for connecting the two U-shaped rubber bodies 21. The monitoring sensors 3 are evenly distributed inside the U-shaped rubber bodies 21. By splitting the rubber ring 2 into two U-shaped rubber bodies 21 and connecting them through the connecting component 22, during installation, the two U-shaped rubber bodies 21 can be fitted onto the bridge support 1 from both sides and then connected and fixed using the connecting component 22. This reduces the difficulty of operation, improves construction efficiency, and facilitates the disassembly and maintenance of the rubber ring 2 in the later stages.

[0030] Specifically, the connecting assembly 22 includes a first connecting block 221 and a second connecting block 222 respectively fixedly connected to both ends of the U-shaped rubber body 21. One end of the first connecting block 221 has a T-slot 223, and one end of the second connecting block 222 has a T-block 224. A locking groove 225 is provided on one side of the T-block 224. A cavity is formed inside the first connecting block 221, and a screw 226 is rotatably installed within the cavity. A slider 227 is threaded onto the screw 226, and a locking block 228 is fixedly connected to one side of the slider 227, extending through the T-slot 223. A driving component 229 for driving the screw 226 to rotate is provided on one side of the first connecting block 221. A limiting rod 2213 is fixedly installed within the cavity, and the slider 227 is slidably sleeved on the limiting rod 2213. By setting the connecting assembly 22, when connecting the two U-shaped rubber bodies 21, the T-block of the second connecting block 222 can be... 224 slides into the T-slot 223 of the first connecting block 221. Then, simply operate the driving component 229 to make the driving component 229 drive the screw 226 to rotate. The screw 226 drives the slider 227 to slide along the limit rod 2213, so that the slider 227 drives the locking block 228 to insert into the locking groove 225. This allows the two U-shaped rubber bodies 21 to be quickly connected. When disassembly is required later, simply reverse the operation of the driving component 229 to make the driving component 229 drive the screw 226 to rotate in the opposite direction. The screw 226 drives the slider 227 to slide in the opposite direction along the limit rod 2213, so that the slider 227 drives the locking block 228 to move out of the locking groove 225. This allows the two U-shaped rubber bodies 21 to be separated and removed from the bridge support 1. This facilitates the connection and disassembly of the two U-shaped rubber bodies 21, reduces the difficulty of operation, improves construction efficiency, and facilitates the disassembly and maintenance of the rubber ring 2 later.

[0031] Specifically, the driving component 229 includes a worm gear 2291 rotatably mounted in the cavity and a worm wheel 2292 fixedly connected to the screw 226. The worm gear 2291 and the worm wheel 2292 are meshed together. A groove 2210 is provided on one side of the first connecting block 221. A handwheel 2293 is provided in the groove 2210. The handwheel 2293 is fixedly connected to one end of the worm gear 2291. By setting the driving component 229, the handwheel 2293 can be manually rotated during operation, so that the handwheel 2293 drives the worm gear 2291 to rotate, and the worm gear 2292 drives the screw 226 to rotate.

[0032] Furthermore, a cover plate 2211 is hinged to the side of the first connecting block 221 near the groove 2210. One end of the cover plate 2211 is threaded with a bolt 2212. The cover plate 2211 is fixed to the first connecting block 221 by the bolt 2212. By setting the cover plate 2211, the groove 2210 can be covered when no operation is required, so as to protect the handwheel 2293 and prevent the handwheel 2293 from being damaged and affecting its later use.

[0033] Furthermore, a sealing strip is provided at the joint between the cover plate 2211 and the groove 2210. By providing the sealing strip, the joint between the cover plate 2211 and the groove 2210 can be sealed to prevent moisture from seeping into the groove 2210 from the joint between the cover plate 2211 and the groove 2210, and to prevent the handwheel 2293 from being corroded.

[0034] In practical use, the working principle of this utility model is as follows: First, during installation, two U-shaped rubber bodies 21 can be fitted onto the bridge support 1 from both sides. When connecting the two U-shaped rubber bodies 21, the T-shaped block 224 of the second connecting block 222 can be slid into the T-shaped groove 223 of the first connecting block 221. Then, the handwheel 2293 can be manually rotated to drive the worm gear 2291 to rotate. The worm gear 2291 drives the worm wheel 2292 to rotate, which in turn drives the screw 226 to rotate. The screw 226 drives the slider 227 to slide along the limiting rod 2213, causing the slider 227 to drive the locking block 228 to insert into the locking groove 225. This allows for quick connection of the two U-shaped rubber bodies 21, reducing the difficulty of operation.

[0035] During the monitoring process, when the bridge bearing 1 changes, the rubber ring 2 will also change displacement. The monitoring sensor 3 monitors the spatial distribution of the vertical load. By monitoring and utilizing the spatial distribution of the vertical load, the bearing can be detected to be detached or slipped out. Based on the cumulative horizontal displacement and the total life displacement of the bearing, the remaining life of the bearing can be estimated.

[0036] During disassembly, the bolts 2212 used to fix the cover plate 2211 can be loosened, the cover plate 2211 can be flipped open, and then the handwheel 2293 can be manually rotated in the reverse direction, so that the handwheel 2293 drives the worm gear 2291 to rotate in the reverse direction, which in turn drives the worm wheel 2292 to rotate in the reverse direction, which in turn drives the reverse screw 226 to rotate, which in turn drives the slider 227 to slide in the reverse direction along the limit rod 2213, so that the slider 227 drives the locking block 228 to move out of the locking groove 225, and the two U-shaped rubber bodies 21 can be separated and then removed from the bridge support 1.

[0037] To prevent damage to the handwheel 2293 from affecting its later use, a cover plate 2211 is provided. When operation is not required, the cover plate 2211 can be used to cover the groove 2210 to protect the handwheel 2293.

[0038] In summary, this integrated multi-dimensional health monitoring device for bridges reduces operational difficulty and improves construction efficiency by splitting the rubber ring 2 into two U-shaped rubber bodies 21 and connecting them via a connecting component 22. During installation, the two U-shaped rubber bodies 21 can be fitted onto the bridge support 1 from both sides and then connected and fixed using the connecting component 22. This also facilitates later disassembly and maintenance of the rubber ring 2. By using the connecting component 22, when connecting the two U-shaped rubber bodies 21, the T-shaped block 224 of the second connecting block 222 can slide along the T-shaped groove 223 of the first connecting block 221. Then, only the driving component 229 needs to be operated. During operation, the handwheel 2293 can be manually rotated, causing the handwheel 2293 to drive the worm gear 2291 to rotate. The worm gear 2291 drives the worm wheel 2292 to rotate, which in turn drives the screw 226 to rotate. The screw 226 then drives the slider 227 to slide along the limiting rod 2213, causing the slider 227 to... The movable locking block 228 is inserted into the locking groove 225 to quickly connect the two U-shaped rubber bodies 21. When no operation is required, the cover plate 2211 can be used to cover the groove 2210 to protect the handwheel 2293. During disassembly, the bolts 2212 that secure the cover plate 2211 can be loosened, the cover plate 2211 can be flipped open, and then the handwheel 2293 can be manually rotated in the reverse direction to drive the worm gear 2291 to rotate in the opposite direction. The worm gear 2292 rotates in the opposite direction, causing the worm gear 2292 to drive the reverse screw 226 to rotate. The screw 226 drives the slider 227 to slide in the opposite direction along the limit rod 2213, causing the slider 227 to move the locking block 228 out of the locking groove 225. This allows the two U-shaped rubber bodies 21 to be separated and removed from the bridge support 1. This facilitates the connection and disassembly of the two U-shaped rubber bodies 21, reduces the difficulty of operation, improves construction efficiency, and also facilitates the disassembly and maintenance of the rubber ring 2 in the later stages.

[0039] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
