Abstract
Description
Technical Field
[0001] This invention relates to the field of bridge bearing monitoring technology, specifically a graded alarm device and alarm method for bridge plate rubber bearing voiding. Background Technology
[0002] In the field of bridge engineering, plate rubber bearings play a crucial role in transferring loads and adapting to deformation. However, due to various factors such as construction errors, bearing aging, and uneven foundation settlement, the phenomenon of plate rubber bearings coming loose occurs from time to time.
[0003] Traditional detection methods rely heavily on manual periodic inspections. This approach is not only inefficient and difficult to monitor in real time, but also highly susceptible to subjective interference, making it difficult to guarantee accuracy. It cannot promptly and accurately detect different degrees of voiding problems and issue effective warnings, causing bridges to operate under potential safety hazards and seriously threatening the durability and safety of bridge structures. Therefore, it is extremely urgent to develop a bridge plate rubber bearing voiding detection device that can automatically monitor and issue graded alarms. Summary of the Invention
[0004] The purpose of this invention is to provide a graded alarm device and method for classifying the voiding of bridge plate rubber bearings, aiming to solve the problem in the prior art that it is impossible to alarm in a timely manner for different voiding levels of the bearings.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bridge plate rubber bearing detachment graded alarm device includes: an upper steel plate, a bridge plate is embedded and fixedly connected to the upper side of the upper steel plate, an outer shell is fixedly installed on the lower side of the bridge plate and on one side of the upper steel plate, a rubber plate is connected to the lower coupling surface of the upper steel plate, a lower steel plate is connected to the lower coupling surface of the rubber plate, and a bearing pad is embedded and fixedly connected to the lower side of the lower steel plate. The shell has an internal pop-out component, and a graded alarm component is located on the upper side of the pop-out component.
[0006] A graded alarm method for bridge plate rubber bearing voiding includes the following steps: S1: First, install the bridge plate rubber bearing void classification alarm device on the lower side of the bridge plate and on one side of the upper steel plate. Ensure that the installation position of each component is accurate and stable, so that the device always maintains a relatively static and stable state with the upper steel plate and the bridge plate. At this time, the hard sheet is located on the lower side of the upper steel plate and is close to the upper steel plate, with one end in contact with the top side of the rubber block, ensuring that the device can work normally. S2: When the bridge bearing is in normal working condition and has not become dislodged, the device is in the initial state. At this time, the first spring is in the compressed state and the second spring is in the stretched state. S3: When the support initially becomes dislodged, the upper steel plate and the rubber plate tilt and separate. Under the action of the first spring and the second spring, the first slide rod moves to a certain extent. The movement of the second slide rod drives the magnet to move. At this time, the magnet moves to the bottom of the first-level magnetic control switch, causing the cloud alarm device to send a first-level alarm to the bridge maintenance center, indicating that the bridge support is slightly dislodged, with a dislodged degree of 25%. S4: When the support further detaches, the angle of tilting and separation between the upper steel plate and the rubber plate increases, the first sliding rod moves further, and at this time the magnet moves to the bottom of the secondary magnetic control switch, causing the cloud alarm device to send a secondary alarm to the bridge maintenance center, indicating that the bridge support detachment is serious, with a detachment degree of 50%. S5: When the support is completely dislodged, the upper steel plate and the rubber plate are completely separated. The first sliding rod moves further, and the magnet moves below the third-level magnetic control switch, causing the cloud alarm device to send a third-level alarm to the bridge maintenance center, indicating that the bridge support is seriously dislodged, with a dislodged degree of 80%.
[0007] The beneficial effects of this invention are: 1. In use, this invention enables real-time monitoring of the detachment status of bridge plate rubber bearings via a tiered alarm system. This tiered alarm system allows bridge management departments to take timely and precise measures, effectively preventing further damage to the bridge structure caused by bearing detachment and ensuring the safe operation of the bridge. 2. Compared to traditional manual inspection methods, this device is not limited by inspection cycles or the experience of inspectors. It can detect and alarm on the condition of bearing detachment in real time and automatically, greatly improving the accuracy and reliability of detection, avoiding misjudgments and omissions that may occur during manual inspection, and providing strong technical support for the long-term safety maintenance of bridges.

Detailed Implementation
[0010] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0011] Example 1: This example provides a graded alarm device for the separation of beam-plate rubber bearings, such as... Figure 1-5 As shown, it includes: an upper steel plate 1, a bridge plate 5 is fixedly connected to the upper side of the upper steel plate 1, an outer shell 3 is fixedly installed on the lower side of the bridge plate 5 and on one side of the upper steel plate 1, a rubber plate 6 is connected to the lower coupling surface of the upper steel plate 1, a lower steel plate 4 is connected to the lower coupling surface of the rubber plate 6, and a support pad stone 2 is fixedly connected to the lower side of the lower steel plate 4. The interior of the outer casing 3 is equipped with a pop-up component, and a graded alarm component is installed on the upper side of the pop-up component.
[0012] In this embodiment, when the bridge plate rubber bearing becomes detached, the contact state between the rubber plate 6 and the upper steel plate 1 changes, causing the rubber plate 6 and the upper steel plate 1 to separate at different levels. At this time, the upper steel plate 1 is displaced, the drive component drives the pop-out component to displace and triggers the graded alarm component, which sends different levels of alarms to the bridge maintenance personnel, so that the bridge maintenance personnel can more accurately understand the detachment status of the upper steel plate 1 and take corresponding maintenance measures to reduce the degree of bridge structural damage caused by the deterioration of the detachment problem.
[0013] Example 2, based on Example 1, such as Figure 1-5 As shown, the pop-out component includes a sleeve 17 disposed at the bottom of the outer shell 3, a fixing plate 10 disposed on one side of the sleeve 17, and mounting holes 9 disposed on the fixing plate 10 for fixed installation with the outer shell 3. A fixing rod 12 is fixedly installed at the tail of the sleeve 17. A first spring 18 is fixedly connected to one end of the fixing rod 12, and a first slide rod 8 is fixedly connected to the other end of the first spring 18. A rigid sheet 7 is fixedly connected to the other end of the first slide rod 8. A slider 15 is fixedly connected to the upper side of the first slide rod 8, and a second spring 16 is elastically connected between the slider 15 and the outer shell 3.
[0014] In this embodiment, when the bridge plate rubber bearing becomes detached, the upper steel plate 1 moves upward, causing the outer shell 3 to move. The upper steel plate 1 and the rubber plate 6 separate at different levels. The level of detachment between the upper steel plate 1 and the rubber plate 6 determines the distance that the rigid sheet 7 can move. At this time, the first spring 18 is in a compressed state and the second spring 16 is in a stretched state. Under the action of the first spring 18 and the second spring 16, the first slide rod 8 moves. The movement of the first slide rod 8 causes the rigid sheet 7 to move. At the same time, the movement of the first slide rod 8 triggers the graded alarm component to issue alarms at different levels.
[0015] Example 3, based on Example 2, such as Figure 1-5 As shown, the graded alarm component includes a second slide bar 19 fixedly installed on the upper side of the end of the first slide bar 8, a magnet 11 fixedly installed on the upper end of the second slide bar 19, a cloud alarm device 14 fixedly installed on the top inside the housing 3, and three magnetic switches 13 that cooperate with the magnet 11 installed below the cloud alarm device 14.
[0016] In this embodiment, the movement of the first slide bar 8 drives the movement of the second slide bar 19, and the movement of the second slide bar 19 drives the movement of the magnet 11. The magnetic control switch 13 is a reed switch type magnetic control switch. Depending on the degree of separation between the upper steel plate 1 and the rubber plate 6, the magnet 11 moves below different magnetic control switches 13, thereby forming different closed loops between different magnetic control switches 13 and the cloud alarm device 14. This allows the cloud alarm device 14 to report the bridge separation status to the bridge maintenance center, triggering alarms of different levels and realizing remote monitoring of the bridge separation status.
[0017] Working principle: When the bridge plate rubber bearing is in normal condition, the rubber plate 6, bearing pad 2, and other components work together to bear the load transmitted from the bridge, and the entire device is stable under force. When the bridge plate rubber bearing experiences a gap, the upper steel plate 1 moves upward, causing the outer shell 3 to move. At this time, different levels of gap separation occur between the upper steel plate 1 and the rubber plate 6. The degree of gap separation between the upper steel plate 1 and the rubber plate 6 determines the distance that the rigid sheet 7 can move. At this time, the first spring 18 is in a compressed state, and the second spring 16 is in a stretched state. Under the action of the first spring 18 and the second spring 16, the first sliding rod 8 moves. The rigid sheet 7 is moved; the first slide bar 8 moves, causing the second slide bar 19 to move, and the second slide bar 19 moves, causing the magnet 11 to move. Depending on the degree of separation between the upper steel plate 1 and the rubber plate 6, the magnet 11 moves to the bottom of different magnetic control switches 13, thereby forming different closed loops between the different magnetic control switches 13 and the cloud alarm device 14. This allows the cloud alarm device 14 to report the bridge separation status to the bridge maintenance center, triggering alarms of different levels. This enables bridge maintenance personnel to more accurately understand the separation status of the upper steel plate 1 and take corresponding maintenance measures to reduce the degree of bridge structural damage caused by the deterioration of the separation problem.
[0018] Based on the above process, this solution provides a graded alarm method for the separation of bridge plate rubber bearings, specifically including the following steps: S1: First, install the bridge plate rubber bearing void classification alarm device on the lower side of the bridge plate 5 and on one side of the upper steel plate 1. Ensure that the installation position of each component is accurate and stable, so that the device always maintains a relatively static and stable state with the upper steel plate 1 and the bridge plate 5. At this time, the hard sheet 7 is located on the lower side of the upper steel plate 1 and is close to the upper steel plate 1, with one end in contact with the top side of the rubber block 6, ensuring that the device can work normally. S2: When the bridge support is in normal working condition and has not come out of the air, the device is in the initial state. At this time, the first spring 18 is in the compressed state and the second spring 16 is in the stretched state. S3: When the support initially becomes dislodged, the upper steel plate 1 and the rubber plate 6 tilt and separate. Under the action of the first spring 18 and the second spring 16, the first sliding rod 8 moves to a certain extent. The second sliding rod 19 moves and drives the magnet 11 to move. At this time, the magnet 11 moves to the bottom of the first-level magnetic control switch 13, so that the cloud alarm device 14 sends a first-level alarm to the bridge maintenance center, indicating that the bridge support is slightly dislodged, with a dislodged degree of 25%. S4: When the support further detaches, the angle of tilting and separation between the upper steel plate 1 and the rubber plate 6 increases, and the first sliding rod 8 moves further. At this time, the magnet 11 moves below the secondary magnetic control switch 13, causing the cloud alarm device 14 to send a secondary alarm to the bridge maintenance center, indicating that the bridge support is seriously detached, with a detachment degree of 50%. S5: When the support is completely dislodged, the upper steel plate 1 and the rubber plate 6 are completely separated. The first sliding rod 8 moves further, and the magnet 11 moves below the three-level magnetic control switch 13, causing the cloud alarm device 14 to send a three-level alarm to the bridge maintenance center, indicating that the bridge support is seriously dislodged and the degree of dislodging is 80%.
