Description

Technical Field

[0001] This utility model relates to the field of bridges, and in particular to a bridge health monitoring bearing. Background Technology

[0002] With the rapid development of bridge engineering technology and large building structures, people are paying more and more attention to the safety and durability of bridges and large buildings. As a result, health monitoring systems have emerged. Health monitoring systems mainly acquire various data reflecting structural behavior through sensors that measure various responses, providing scientific reference for analyzing the health status of structures and assessing their reliability.

[0003] Chinese Patent Publication No. CN207567644U discloses a bridge health monitoring bearing, including an upper bearing plate and a lower bearing plate, with an intermediate liner between the upper and lower bearing plates. The top surface of the lower bearing plate has a basin, and an oil cavity is provided inside the basin. An elastic layer is provided on the top of the oil cavity. At least two oil passages connected to the oil cavity are provided on the side of the lower bearing plate. However, existing devices have some shortcomings. Existing devices generally monitor the health of the bridge by installing a monitoring sensor at the top of the bearing. However, since a shock absorber is installed at the top of the bearing, the bridge structure at this location is less susceptible to damage. Monitoring this location cannot represent the health of the entire bridge structure, thus affecting the monitoring data. Therefore, we propose a bridge health monitoring bearing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a bridge health monitoring bearing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a further embodiment, both support components include support blocks, which are located at the top of two support piers respectively. The upper surfaces of both support blocks are provided with grooves, and two bearing dampers are installed on the upper surfaces of the two grooves. The tops of the two sets of bearing dampers are in contact with the bottom surface of the bridge body.

[0008] In a further embodiment, the mounting assembly includes two mounting slots and two connecting fixing plates. The two mounting slots are respectively located on the outer surfaces of the two supporting piers, and the two connecting fixing plates are respectively located on the outer surfaces of the two mounting slots. Support fixing plates are installed on the outer surfaces of the two connecting fixing plates by multiple bolts. A horizontal steel frame is installed on one side of the two support fixing plates that are close to each other.

[0009] In a further embodiment, both connecting components include connecting steel frames, both connecting steel frames are located on the upper surface of the horizontal steel frame, and support plates are installed at both ends of both connecting steel frames.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a bridge health monitoring bearing. By installing an installation component and a connecting component between two supporting piers, and installing multiple multi-dimensional force sensors above the connecting component, the monitoring sensors can be moved away from the shock absorber at the top of the bearing. This allows the monitoring sensors to monitor the location of normal damage to the bridge, thereby providing a better understanding of the bridge's health condition. Therefore, this device effectively solves the problem of inaccurate monitoring data caused by installing the monitoring sensors at the top of the bearing in existing devices.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a bridge health monitoring support includes a bridge body 1. Two supporting piers 2 are installed on the bottom surface of the bridge body 1. Each supporting pier 2 has a casting component 3 at its bottom end and a supporting component 5 at its top. An installation component 7 is installed on the outer surface of both supporting piers 2. Two connecting components 6 are installed on the upper surface of the installation component 7. Two monitoring components 4 are installed on the upper surface of each connecting component 6. Each monitoring component 4 includes a multi-dimensional force sensor 10. Each multi-dimensional force sensor 10 is located on the upper surface of a supporting plate 20, and the top of each multi-dimensional force sensor 10 is in contact with the bottom surface of the bridge body 1. Multiple multi-dimensional force sensors are installed above the connecting components 6. Force sensor 10 allows the monitoring sensor to be located away from the shock absorber at the top of the support, enabling the monitoring sensor to monitor the location of normal damage to the bridge, thereby providing a better understanding of the bridge's health. Among them, multi-dimensional force sensor 10 is a force sensor that can simultaneously measure force and torque components in two or more directions. In the Cartesian coordinate system, force and torque can each be decomposed into three components. Therefore, the most common multi-dimensional force sensor 10 is a six-dimensional force and torque sensor, that is, a sensor that can simultaneously measure three force components and three torque components. Using multi-dimensional force sensor 10, vertical loads can be monitored to assess overload risk; horizontal shear force can be detected to determine abnormal support slippage; and bending moment can be measured to reflect torsion or eccentric compression of the beam.

[0023] Both support components 5 include support blocks 13, which are located at the top of the two support piers 2 respectively. The upper surface of each support block 13 is provided with a groove 12, and two bearing dampers 14 are installed on the upper surface of each groove 12. The top of each set of bearing dampers 14 is in contact with the bottom surface of the bridge body 1. The bearing damper 14 is a device used to reduce and disperse the vibration energy of the structure under the action of external forces such as earthquakes. It is mainly used in large structures such as bridges and buildings. Its principle is to reduce the vibration amplitude and damage of the structure by absorbing and consuming vibration energy.

[0024] The mounting assembly 7 includes two mounting slots 16 and two connecting fixing plates 15. The two mounting slots 16 are located on the outer surfaces of the two supporting piers 2, and the two connecting fixing plates 15 are located on the outer surfaces of the two mounting slots 16. Support fixing plates 18 are mounted on the outer surfaces of the two connecting fixing plates 15 by multiple bolts 19. A horizontal steel frame 17 is mounted on the side of the two supporting fixing plates 18 that are close to each other. By using bolts 19 to fix the connecting fixing plates 15 and the supporting fixing plates 18, the device can be easily installed and disassembled.

[0025] Both connecting components 6 include connecting steel frames 11, both connecting steel frames 11 are located on the upper surface of the horizontal steel frame 17, and both ends of the two connecting steel frames 11 are equipped with support plates 20, which can support the sensors inside the monitoring component 4.

[0026] Both casting components 3 include a base 8, which is located at the bottom of the two supporting piers 2. The bottom surface of both bases 8 is cast with casting blocks 9, which ensures the stability of the supporting piers 2.

[0027] The working principle of this utility model is as follows:

[0028] When this type of bridge health monitoring bearing is used, the staff first installs the installation component 7 between two supporting piers 2, and then installs the monitoring component 4 on the upper surface of the two connecting components 6, so that the multiple multi-dimensional force sensors 10 in the monitoring component 4 are supported by the bottom surface of the bridge body 1. Then, the monitoring component 4 is used in conjunction with the background computer to monitor the health of the bridge body 1. Finally, the staff makes a judgment on the health of the bridge body 1 and takes corresponding protective measures based on the monitoring data.
