Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, specifically to an elastic damping bridge bearing with remote monitoring. Background Technology

[0002] With social progress and the improvement of people's living standards, many cities are now vigorously constructing overpasses and cross-sea bridges to alleviate traffic congestion. Bridges are a key component of road traffic, and bridge bearings are a crucial part of bridge construction. They are designed to accommodate the effective load, deformation, and rotation of the bridge beam and transfer the superstructure load to the pier foundation. The installation quality of the bearings directly affects the operational safety of the bridge. The load, deformation, and rotation of the bridge beam, as well as the installation quality of the bearings, are all of paramount importance to bridge safety. At the same time, bridge bearings play a vital role in connecting the upper and lower structures. To prevent accidents caused by bearing installation, easy-to-construct, advanced, and high-performance bridge bearings are the preferred choice for bridge engineering.

[0003] Currently, bridge bearings in existing technology can be divided into three main categories according to their structure: plate rubber bearings, pot bearings, and spherical bearings. These three types of bridge bearings are mostly simple in structure and have relatively limited functionality. For example, the commonly used plate rubber bearing, although possessing good elastic damping and effectively mitigating the impact of vehicles on bridges, is prone to aging and deterioration over time due to its simple construction. This leads to a decrease in the bearing's elasticity and load-bearing capacity, affecting its service life and performance stability. Furthermore, it cannot meet the requirements of large bridges or structures with high load-bearing requirements. Because it is susceptible to environmental and load-bearing influences, it requires regular inspection and maintenance, resulting in high maintenance costs and a large workload. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an elastic damping bridge bearing with remote monitoring, which solves the problems of existing plate rubber bearings being prone to aging and deterioration over time, failing to meet the requirements of large bridges or structures with high load-bearing requirements, and having high maintenance costs and workload.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elastic damping bridge bearing with remote monitoring, comprising a base and a top seat, wherein rings are fixedly connected to opposite sides of the base and the top seat, two energy storage components are fixedly connected to the outer wall of the bottom ring, a buffer component is provided between the two rings, a monitoring component is provided on the upper surface of the base, and mounting seats are connected to the four corners of the upper surface of the base, a movable rod is slidably connected to the middle of each mounting seat, a spring is provided inside each mounting seat, a mounting groove is provided through the middle of each mounting seat, a rocker arm is rotatably connected to the inner wall of the mounting groove, the upper and lower ends of the spring are respectively provided between the movable rod and the rocker arm, a limit frame is fixedly connected to the top of the outer wall of each mounting seat, a top rod is slidably connected to the middle of the limit frame, and the bottom end of the top rod contacts the upper surface of the rocker arm.

[0006] Preferably, the buffer assembly includes two rubber seats, which are respectively disposed inside two rings. Multiple limiting grooves are provided on opposite sides of the two rings. Two sets of sliders are slidably connected to the inner wall of each set of limiting grooves. Movable rods are rotatably connected to opposite sides of the upper and lower sets of sliders. The intersection of two movable rods is rotatably connected. A damper is rotatably connected to the outer wall of each set of movable rods. The other end of the damper is rotatably connected to the outer wall of the bottom ring.

[0007] Preferably, the monitoring component includes two sets of measuring cylinders. The lower surfaces of the two sets of measuring cylinders are fixedly connected to the upper surface of the base. Pistons are slidably connected to the inner walls of both sets of measuring cylinders. A moving rod is fixedly connected to the upper surface of each piston. The outer wall of the moving rod is slidably connected to the middle of the measuring cylinder. The top end of the moving rod contacts the lower surface of the top seat. A spring is sleeved on the outside of the moving rod. A graduated glass plate is provided on opposite sides of each set of measuring cylinders. Two protective covers are fixedly connected to the outer wall of the bottom ring. Laser measuring devices are installed on the left and right sides of the two protective covers. The laser head of each laser measuring device is aligned with the direction of the piston.

[0008] Preferably, the distance between the movable rod 2 and the top seat is equal to the distance of the rubber seat exposed outside the ring.

[0009] Preferably, the energy storage assembly includes two protective boxes, the outer walls of the two protective boxes are fixedly connected to the outer wall of the bottom ring, the two protective boxes are equipped with batteries, the two batteries are connected to a controller, and the controller is connected to a solar panel.

[0010] Preferably, the solar panel is mounted on the outer edge of the bridge via a bracket, and the protective box has multiple heat dissipation holes running through its center.

[0011] Preferably, the two sets of measuring cylinders are arranged in a rectangular shape, and the length of the rocker arm exposed outside the mounting base is greater than the length disposed inside the mounting base.

[0012] Working Principle: When using the bridge bearing of this invention, the solar panel is pre-installed on the outer edge of the bridge. Then, the base and top seat are installed between the bridge and the bearing pad, respectively. After installation, during use, due to the gravity of the upper bridge, the bridge bearing will transmit the supporting reaction force of the superstructure. Affected by gravity, the top seat will move downwards. As time progresses, the service life of the bridge bearing will decrease. The top seat will slowly descend. During this descent, the upper ring will increase the distance between the upper and lower ends of the two intersecting movable rods, simultaneously driving the sliders on both sides within the limiting groove. The wall moves in the opposite direction, causing the damper to contract. Simultaneously, under the action of the damper, the two intersecting movable rods return to their original position, thereby reducing the impact of deformation between the two rubber seats. This provides elastic damping for the bridge bearing and extends its service life. Over time, the bridge bearing will inevitably deform to some extent. As the top seat moves downward, the compression deformation between the two rubber seats causes the top seat to compress the movable rod, causing it to descend inside the measuring cylinder. Simultaneously, it compresses the spring. In the initial stage, when the deformation is small... At this time, the rebound force generated by the compressed spring will also be applied to the top seat, thereby helping the buffer assembly reduce the impact of the upper gravity on the top seat. When the moving rod moves down too far, causing the piston to move down more than the safe distance inside the measuring cylinder, it will be detected in time by the laser monitoring of the laser measuring device, and the detection result will be sent to the monitoring terminal to warn the maintenance personnel. At the same time, when the deformation between the two rubber seats is too large, causing the top seat to contact the top of the moving rod two and gradually move down, the moving rod two will move down inside the mounting seat, thereby compressing the spring two and counteracting the tilting motion. The rod is pressed down at one end of the mounting base, causing the end of the lever outside the mounting base to tilt upwards, thereby pushing the top rod upwards inside the limit frame. The greater the downward force, the greater the upward force of the top rod, thus ensuring improved overall safety and providing more maintenance time for subsequent repairs. In daily use, to ensure the normal operation of the monitoring component, the solar panels installed on the outer edge of the bridge absorb light energy, which is then converted into electrical energy by the controller. This electrical energy is stored in the battery and powered by the battery through the connection of the wires.

[0013] This invention provides an elastic damping bridge bearing with remote monitoring. It has the following advantages: 1. This invention reduces the gravitational impact of the superstructure load on the bridge bearings by utilizing the elastic damping effect of the buffer components, thereby improving the service life of the bridge and enhancing its stability and reliability.

[0014] 2. This invention monitors the downward displacement of the top seat and the deformation between the two rubber seats using a laser measuring device. It can detect abnormalities in a timely manner and send warning information to the monitoring terminal to remind maintenance personnel to perform necessary maintenance and repairs, thereby ensuring the safe operation of the bridge bearing.

[0015] 3. This invention uses solar panels installed on the outer edge of the bridge to absorb light energy, convert it into electrical energy, and store it in a battery to provide a stable power supply for the laser measuring device, ensuring the normal operation of the monitoring components.

[0016] 4. Through the synergistic action of components such as the movable rod, spring, and rocker arm, this invention ensures that appropriate elasticity and stability are maintained during the downward movement of the top seat, thereby improving the safety of the entire structure and providing sufficient time and conditions for subsequent maintenance work.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Please see the appendix Figure 1 and attached Figure 5 This invention provides an elastic damping bridge support with remote monitoring, including a base 1 and a top seat 2. Rings 3 are fixedly connected to opposite sides of the base 1 and top seat 2. Two energy storage components are fixedly connected to the outer wall of the bottom ring 3. A buffer component is provided between the two rings 3. A monitoring component is provided on the upper surface of the base 1. Mounting seats 20 are connected to the four corners of the upper surface of the base 1. A movable rod 21 is slidably connected to the middle of each mounting seat 20. A spring 22 is provided inside each mounting seat 20. A mounting groove 23 is provided through the middle of each mounting seat 20. A rocker arm 24 is rotatably connected to the inner wall of the mounting groove 23. The upper and lower ends of the spring 22 are respectively located between the movable rod 21 and the rocker arm 24. A limit frame 25 is fixedly connected to the top of the outer wall of each mounting seat 20. A top rod 26 is slidably connected to the middle of the limit frame 25. The bottom end of the top rod 26 contacts the upper surface of the rocker arm 24.

[0021] Specifically, during daily use, the rubber seat 4 inside the ring 3 will age and deteriorate over time, causing deformation. Under the action of deformation, the top seat 2 will move downward, thereby squeezing the movable rod 21 and causing it to move downward in the middle of the mounting seat 20. This will drive the spring 22 to move downward and compress it, causing the other end of the rocker arm 24 to lift up. This will then push the top rod 26 upward in the middle of the limit frame 25, thereby lifting the top seat 2 upward. This ensures that the top seat 2 can maintain appropriate elasticity and stability during the downward movement of the top seat 2, improving the safety of the entire structure and providing sufficient time and conditions for subsequent maintenance work.

[0022] Please see the appendix Figure 4 The buffer assembly includes two rubber seats 4, which are respectively set inside two rings 3. Multiple limiting grooves 5 are opened on the opposite sides of the two rings 3. Two sets of sliders 6 are slidably connected to the inner wall of each set of limiting grooves 5. The opposite sides of the upper and lower sets of sliders 6 are rotatably connected to movable rods 7. The intersection of the two movable rods 7 is rotatably connected. A damper 8 is rotatably connected to the outer wall of each set of movable rods 7. The other end of the damper 8 is rotatably connected to the outer wall of the bottom ring 3.

[0023] Specifically, during daily use, the top seat 2 will be affected by the gravity of the upper load and move downwards, affecting the rubber seats 4 inside the upper and lower rings 3. This causes the intersecting movable rods 7 to move in opposite directions, reducing the distance between the upper and lower ends. This causes the sliders 6 on both sides to slide in opposite directions inside the limiting grooves 5. Subsequently, under the action of the damper 8, the intersecting movable rods 7 are reset, eliminating most of the gravity effect and playing an elastic damping role. This reduces the gravity effect of the upper load on the bridge support, improves the service life of the bridge, and enhances its stability and reliability.

[0024] Please see the appendix Figure 2 - Appendix Figure 3 The monitoring component includes two sets of measuring cylinders 9. The lower surfaces of the two sets of measuring cylinders 9 are fixedly connected to the upper surface of the base 1. Pistons 10 are slidably connected to the inner walls of the two sets of measuring cylinders 9. A moving rod 11 is fixedly connected to the upper surface of each piston 10. The outer wall of the moving rod 11 is slidably connected to the middle of the measuring cylinder 9. The top of the moving rod 11 contacts the lower surface of the top seat 2. A spring 12 is sleeved on the outside of the moving rod 11. A scale glass plate 13 is provided on the opposite side of each set of measuring cylinders 9. Two protective covers 14 are fixedly connected to the outer wall of the bottom ring 3. Laser measuring devices 15 are installed on the left and right sides of the two protective covers 14. The laser head of each laser measuring device 15 is aligned with the direction of the piston 10.

[0025] Specifically, as time goes by, under the action of the upper load, the top seat 2 will move downward, which will push the moving rod 11 downward, and then drive the piston 10 to move downward on the inner wall of the measuring cylinder 9. When the piston 10 moves to a large distance, the laser measuring instrument 15 will immediately monitor the position of the piston 10 through the scale glass plate 13, and then transmit the detection data to the monitoring terminal to remind maintenance personnel to carry out necessary maintenance and repair to ensure the safe operation of the bridge bearing.

[0026] The distance between the movable rod 21 and the top seat 2 is equal to the distance of the rubber seat 4 exposed outside the ring 3.

[0027] Specifically, this design ensures that the component can promptly drive the jacking rod 26 to lift when the bridge bearing's service life is low and the load it can withstand is small. This stabilizes the bridge bearing and provides sufficient time for subsequent maintenance. Simultaneously, a sufficient distance is maintained between the movable rod 21 and the jacking rod 2, allowing the bearing to more effectively buffer vibrations and reduce the impact of structural stress, improving the stability and reliability of the bearing structure and ensuring it maintains good working condition during use.

[0028] Please see the appendix Figure 2 Appendix Figure 6 and attached Figure 7The energy storage assembly includes two protective boxes 16. The outer walls of the two protective boxes 16 are fixedly connected to the outer wall of the bottom ring 3. The two protective boxes 16 are equipped with batteries 18. The two batteries 18 are connected to a controller, and the controller is connected to a solar panel 19.

[0029] Specifically, the protection box 16 ensures that the internal battery 18 is not damaged by the external environment during daily use. When in use, the solar panel 19 absorbs light energy and converts it into electrical energy, which is stored by the battery 18 under the control of the controller and used by the laser measuring device 15 to ensure the normal operation of the monitoring components.

[0030] The solar panel 19 is mounted on the outer edge of the bridge via a bracket, and the protective box 16 has multiple heat dissipation holes 17 running through the middle.

[0031] Specifically, the solar panel 19 is installed on the outer edge of the bridge to facilitate the absorption of light energy by the solar panel 19. The multiple heat dissipation holes 17 set on the protective box 16 are not only for heat dissipation of the internal battery 18, but also facilitate the passage of wires to connect and power the laser measuring device 15.

[0032] The two sets of measuring cylinders 9 are arranged in a rectangular shape, and the length of the rocker arm 24 exposed outside the mounting base 20 is greater than the length set inside the mounting base 20.

[0033] Specifically, the rectangular arrangement of the two sets of measuring cylinders 9 can evenly receive forces from the top plate in four directions, ensuring the stability of the bridge support under stress. At the same time, the length of the rocker arm 24 exposed outside the mounting base 20 is greater than the length set inside the mounting base 20, which facilitates a larger rocker height, which is sufficient to support the top plate.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
