Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bridge monitoring, and in particular to a bridge structure dynamic monitoring and deviation correction device. Background Art
[0002] In bridge engineering, the connection and support between the bridge and the pier is a key link to ensure the safety and stability of the bridge structure. Traditionally, rubber blocks are often used as shock-absorbing elements in this connection. The high elasticity and buffering performance of the rubber blocks can effectively absorb and disperse the vibration and impact caused by vehicle loads, wind, temperature changes and other factors during the operation of the bridge, thereby protecting the bridge structure from damage and extending its service life.
[0003] However, despite the excellent performance of rubber blocks in shock absorption, their application also faces some challenges. First, during long-term use, rubber blocks may experience performance degradation or even failure due to material aging, wear or the continuous action of external loads, causing the connection between the bridge and the pier to become less tight, thereby increasing the risk of bridge displacement. Second, existing rubber pad designs often lack the function of real-time monitoring of bridge displacement, making it difficult for engineers to detect and deal with potential displacement problems in a timely manner. Once displacement occurs, it may seriously affect the safety and stability of the bridge.
[0004] In addition, after the bridge deviates, the close fit between the rubber block and the bridge structure and the complex installation environment make it particularly difficult to reinstall the rubber block during the correction process. Traditional correction methods often require a lot of manpower, material resources and time, and it is difficult to ensure the accuracy and safety during the disassembly and assembly process, further increasing the difficulty and cost of bridge repair. Utility Model Content
[0005] In view of the deficiencies in the prior art, the present application provides a bridge structure dynamic monitoring and correction device, which has the advantages of monitoring, etc. and solves the problems raised in the background technology.
[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a bridge structure dynamic monitoring and deviation correction device, comprising a mounting plate, a rectangular frame is fixedly connected to the upper surface of the mounting plate, and a lifting assembly is arranged inside the rectangular frame;
[0007] The lifting assembly includes a bidirectional threaded rod, two sliders, a plurality of connecting rods and a top plate;
[0008] A rubber block is fixedly mounted on the upper surface of the top plate, and a plurality of notches are opened on the upper surface of the rubber block, wherein a plurality of buffer components and pressure sensors are respectively arranged inside the plurality of notches;
[0009] Each of the buffer components includes a sleeve, a plug rod and a spring;
[0010] A friction plate is arranged between the top ends of the two inner side walls of each notch.
[0011] Through the above scheme, by installing a pressure sensor in the rubber block, the device can monitor the pressure changes between the bridge and the pier in real time, thereby indirectly reflecting the deviation of the bridge.

The buffer component composed of a sleeve, a rod and a spring, combined with the damping properties of the rubber block, significantly improves the shock absorption effect of the device. This dual shock absorption mechanism can effectively absorb and disperse various vibrations and impact forces from the bridge, protecting the bridge structure from damage. A bridge structure dynamic monitoring and correction device, a built-in lifting component of the device, by adjusting the rotation of the two-way threaded rod, can easily realize the rapid adjustment of the height of the rubber block. During the correction, the bridge and the rubber block can be quickly disengaged, which is convenient for technicians to carry out correction work. After the correction is completed, the rubber block can be quickly in contact with the bridge, which improves the installation speed.

[0013] Through the above scheme, the two-way threaded rod is rotated to realize the sliders approaching or moving away from each other, and then the bottom ends of the connecting rods are moved away from or approaching each other, so as to push the hinged top plate up or down, adjust the height of the rubber block, and facilitate disassembly and correction.
[0014] Furthermore, a plurality of telescopic rods arranged in a matrix are fixedly mounted between the top plate and the mounting plate.
[0015] Through the above scheme, by setting the telescopic rod, the up and down movement of the top plate can be limited to ensure the stability of its lifting.
[0016] Furthermore, two groups of mounting holes are provided on the upper surface of the mounting plate.
[0017] Through the above solution, by setting the mounting holes, it is convenient for the user to connect the mounting plate to the bridge pier.
[0018] Furthermore, the bottom end of each sleeve is fixedly connected to the inner bottom wall of the slot adjacent to it, each insertion rod is plugged into the sleeve adjacent to it, the two ends of each spring are respectively fixedly connected to the bottom end of the insertion rod adjacent to it and the inner bottom wall of the sleeve, and the top end of each insertion rod is fixedly connected to the bottom of the friction plate adjacent to it.
[0019] Through the above scheme, by setting the sleeve, the plug and the spring, and cooperating with the damping properties of the rubber block, the shock absorbing performance of the bridge body to the outside world can be enhanced. At the same time, when the rubber block is squeezed, the friction plate and the rubber block can be placed on the same horizontal plane, thereby increasing the friction coefficient with the bottom of the bridge body and slowing down the displacement of the bridge body.
[0020] Furthermore, a wireless data module is installed at the left end of the bottom of the top plate.
[0021] Through the above scheme, by setting up the wireless data transmission module, the purpose of remote transmission of data can be achieved.
[0022] Furthermore, a control host is installed at the right end of the bottom of the top plate, and the wireless data transmission module and the pressure sensor are both electrically connected to the control host.
[0023] Through the above scheme, by controlling the settings of the host, the purpose of processing data and controlling electrical components can be achieved.
[0024] Furthermore, the thread of the bidirectional threaded rod is configured as a self-locking thread.
[0025] Through the above solution, the bidirectional threaded rod is set as a self-locking thread, which can improve the overall stability.
[0026] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0027] This bridge structure dynamic monitoring and correction device can monitor the pressure changes between the bridge and the pier in real time by installing a pressure sensor in the rubber block, thereby indirectly reflecting the deviation of the bridge. Once abnormal deviation is found, the device can immediately transmit the data to the control center or relevant maintenance personnel through the wireless data transmission module, so as to achieve early warning and ensure the safety of the bridge.
[0028] This bridge structure dynamic monitoring and correction device adopts a buffer component composed of a sleeve, a rod and a spring, combined with the damping properties of a rubber block, which significantly improves the shock absorption effect of the device. This dual shock absorption mechanism can effectively absorb and disperse various vibrations and impact forces from the bridge, protecting the bridge structure from damage.

The thread of the two-way threaded rod 301 is set as a self-locking thread. By setting the two-way threaded rod 301 as a self-locking thread, the overall stability can be improved.
[0039] See also Figure 1 , Figure 2 and Figure 3 A plurality of telescopic rods 9 arranged in a matrix are fixedly installed between the top plate 304 and the mounting plate 1. Through the setting of the telescopic rods 9, the up and down movement of the top plate 304 can be limited to ensure the stability of its lifting. A rubber block 4 is fixedly installed on the upper surface of the top plate 304.

[0040] Each buffer assembly 6 includes a sleeve 601, an insert rod 602 and a spring 603;
[0041] See also Figure 1 , Figure 2 and Figure 3 A friction plate 8 is provided between the top ends of the two inner side walls of each slot 5, the bottom end of each sleeve 601 is fixedly connected to the inner bottom wall of the slot 5 adjacent to it, each plug rod 602 is plugged into the sleeve 601 adjacent to it, the two ends of each spring 603 are respectively fixedly connected to the bottom end of the plug rod 602 adjacent to it and the inner bottom wall of the sleeve 601, the top end of each plug rod 602 is fixedly connected to the bottom of the friction plate 8 adjacent to it, through the arrangement of the sleeve 601, the plug rod 602 and the spring 603, and in combination with the damping properties of the rubber block 4, the shock absorbing performance of the bridge body to the outside world can be enhanced, and at the same time, when the rubber block 4 is squeezed, the friction plate 8 and the rubber block 4 can be placed in the same horizontal plane, thereby increasing the friction coefficient with the bottom of the bridge body and slowing down the displacement of the bridge body.
[0042] See also Figure 1 , Figure 2 and Figure 3A wireless data module 11 is installed at the left end of the bottom of the top plate 304. Through the setting of the wireless data transmission module, the purpose of remote transmission of data can be achieved. A control host 12 is installed at the right end of the bottom of the top plate 304. The wireless data transmission module and the pressure sensor 7 are electrically connected to the control host 12. Through the setting of the control host 12, the purpose of data processing and control of electrical components can be achieved.
[0043] In this embodiment, a bridge structure dynamic monitoring and correction device is provided. By installing a pressure sensor 7 in a rubber block 4, the device can monitor the pressure change between the bridge and the pier in real time, thereby indirectly reflecting the deviation of the bridge. Once an abnormal deviation is found, the device can immediately transmit the data to the control center or relevant maintenance personnel through a wireless data transmission module to achieve early warning and ensure the safety of the bridge. The buffer component 6 composed of a sleeve 601, a plug rod 602 and a spring 603 is used. Combined with the damping properties of the rubber block 4, the shock absorption effect of the device is significantly improved. This double shock absorption mechanism can effectively absorb and disperse various vibrations and impact forces from the bridge, and protect the bridge structure from damage. In this bridge structure dynamic monitoring and correction device, the built-in lifting component 3 of the device can easily realize the rapid adjustment of the height of the rubber block 4 by adjusting the rotation of the bidirectional threaded rod 301. During the correction, the bridge and the rubber block 4 can be quickly disengaged, which is convenient for technicians to carry out the correction work. After the correction is completed, the rubber block 4 can be quickly contacted with the bridge, which improves the installation speed.
[0044] The working principle of the above embodiment is as follows: when the bridge is subjected to external factors such as vehicle load, wind force, temperature change, etc., the connecting part between the bridge and the pier, i.e., the rubber block 4, will be subjected to corresponding pressure and deformation. The pressure sensor 7 installed inside the rubber block 4 can sense these pressure and deformation in real time, and transmit the monitored data to the control host 12. The control host 12 processes and analyzes the received data to evaluate the deflection and health of the bridge. Once abnormal deflection or potential risk is found, the control host 12 will immediately start the early warning mechanism. During the normal operation of the bridge, the rubber block 4 and the buffer assembly 6 work together to play a shock-absorbing and buffering role. The rubber block 4 uses its high elasticity and damping properties to absorb and disperse the vibration and impact force from the bridge, and the sleeve 601, the plug rod 602 and the spring 603 in the buffer assembly 6 further enhance the shock-absorbing effect. When the rubber block 4 is squeezed, the plug rod 602 slides in the sleeve 601 and compresses the spring 603 to generate a buffering force; when the pressure is released, the spring 603 returns to its original state and pushes the plug rod 602 to reset.
