Description

Technical Field

[0001] This utility model relates to the field of settlement monitoring, and in particular to a bridge pier settlement monitoring device. Background Technology

[0002] As the core load-bearing components of a bridge structure, the settlement and deformation of bridge piers directly affect the structural stability and traffic safety of the bridge. During the long-term operation of a bridge, due to multiple factors such as changes in geological conditions, accumulated traffic loads, and environmental erosion, bridge piers are prone to uneven settlement or gradual displacement. If timely monitoring and early warning are not provided, serious safety accidents such as bridge deck cracking, bearing failure, or even structural instability may occur. Therefore, accurate and real-time settlement monitoring of bridge piers is a crucial link in ensuring the safe operation and maintenance of bridges throughout their entire life cycle and supporting preventive maintenance decisions.

[0003] Current bridge pier settlement monitoring mainly relies on traditional displacement gauges, total stations, manual measurement, or simple monitoring devices.

[0004] However, existing traditional monitoring devices mostly use welding or multi-bolt fixing methods, which are inconvenient to disassemble and assemble. Moreover, when working on high piers or in busy road sections, auxiliary facilities need to be built or traffic needs to be closed, which is not only inefficient but also poses safety risks. Therefore, a bridge pier settlement monitoring device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bridge pier settlement monitoring device, which aims to solve the problem of inconvenient disassembly and assembly in the prior art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a bridge pier settlement monitoring device, comprising a mounting base, an mounting plate fixedly connected to the top of the mounting base, a limiting plate snapped into the top of the mounting plate, a tank connected to the top of the limiting plate via a horizontal component, a displacement gauge fixedly connected to the top of the tank, a connecting pipe fixedly connected to the bottom of the tank, a slot formed on the outer wall of the limiting plate, a disc rotatably connected to the inner wall of the mounting base, an arc groove formed on the top of the disc, a sliding rod slidably connected to the inner wall of the arc groove, a slider fixedly connected to the top of the sliding rod, a locking block fixedly connected to the top of the slider, a sliding groove formed on the bottom of the inner wall of the mounting base, and a limiting component provided on the outer arc surface of the disc.

[0008] As a further description of the above technical solution: The limiting component includes a limiting frame, which is fixedly connected to the outer arc surface of the disc. The inner wall of the limiting frame is elastically connected to a limiting block through a limiting spring. A limiting rod is fixedly connected to the top of the limiting block. A limiting groove is formed on the top of the mounting base.

[0009] As a further description of the above technical solution: The bottom of the slide rod is slidably connected to the inner wall of the mounting plate, and the slider is slidably connected to the inner wall of the slide groove.

[0010] As a further description of the above technical solution: The card block is slidably connected to the inner wall of the mounting plate, the bottom of the card block is slidably connected to the top of the disc, and the card block is engaged with the inner wall of the card slot.

[0011] As a further description of the above technical solution: The top of the fine-tuning wheel is rotatably connected to the bottom of the tank.

[0012] As a further description of the above technical solution: One end of the limiting spring is fixedly connected to the inner wall of the limiting frame, and the other end of the limiting spring is fixedly connected to the top of the limiting block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the installation process is simplified by setting a snap-fit ​​structure between the limiting plate and the mounting plate. During installation, the operator only needs to align the limiting plate with the corresponding position on the mounting plate and press down gently to complete the initial installation. During disassembly, it can be separated by a simple operation without complicated tools and techniques, which is convenient and quick. In daily maintenance and repair work, technicians can quickly disassemble the limiting plate to inspect and replace internal components, saving a lot of maintenance time.

[0015] 2. In this utility model, the design of the horizontal component also facilitates installation and maintenance. Operators can visually determine the tank's level by observing the level bubble and quickly adjust it by rotating the fine-tuning wheel. The operation is simple and easy to understand. During installation, technicians can adjust the tank to a level position in a short time, ensuring the normal operation of the displacement meter. This precise leveling effectively avoids measurement errors caused by tank tilting, allowing the displacement meter to collect data under optimal working conditions. Attached Figure Description

[0021] Reference Figures 1-3 This utility model provides an embodiment of a bridge pier settlement monitoring device, including a mounting base 1, which serves as the basic support component of the entire monitoring device and is used for stable connection with the surface of the bridge pier. A mounting plate 2 is fixedly connected to the top of the mounting base 1, providing a flat bearing surface for the installation of subsequent components. The fixed connection between the mounting plate 2 and the mounting base 1 is achieved by welding to ensure stability. A limiting plate 3 is snapped into the top of the mounting plate 2, which facilitates the quick installation and disassembly of the limiting plate 3 and can initially limit its horizontal displacement. A tank 4 is connected to the top of the limiting plate 3 through a horizontal component, which can adjust the horizontal state of the tank 4. A displacement gauge 5 is fixedly connected to the top of the tank 4, serving as the core monitoring element for real-time acquisition of pier settlement displacement data. A connecting pipe 6 is fixedly connected to the bottom of the tank 4, which allows for the flow of monitoring media between the inside and outside of the tank 4. A slot 7 is provided on the outer wall of the limiting plate 3, which provides a positioning structure for cooperation with the locking block 12.

[0022] Reference Figures 2-4A disc 8 is rotatably connected to the inner wall of the mounting plate 2. The disc 8 can rotate around the central axis of the mounting plate 2, providing power for the position adjustment of the locking block 12. An arc groove 9 is formed on the top of the disc 8. The trajectory of the arc groove 9 is designed to match the rotation radius of the disc 8. A slide rod 10 is slidably connected to the inner wall of the arc groove 9. The slide rod 10 can slide along the trajectory of the arc groove 9, thereby driving the movement of subsequent components. A slider 11 is fixedly connected to the top of the slide rod 10. The slider 11 serves to connect the slide rod 10 and the locking block 12. The locking block 12 is fixedly connected to the top of the slider 11. The locking block 12 is the key to realizing the locking and fixing of the limiting plate 3 and the mounting plate 2. The key component has a groove 13 at the bottom of the inner wall of the mounting plate 2. The groove 13 provides guidance and limit for the sliding of the slider 11, preventing the slider 11 from deviating from the movement trajectory. The outer arc surface of the disc 8 is provided with a limit component. The limit component is used to fix the disc 8 after it rotates to the designated position, so as to prevent the disc 8 from rotating on its own and affecting the locking effect. The bottom of the slide rod 10 is slidably connected to the inner wall of the mounting plate 2. The slider 11 is slidably connected to the inner wall of the groove 13. The locking block 12 is slidably connected to the inner wall of the mounting plate 2. The bottom of the locking block 12 is slidably connected to the top of the disc 8. The locking block 12 is locked into the inner wall of the locking groove 7.

[0023] Reference Figures 1-2 The leveling component includes a fine-tuning wheel 19, which adopts a threaded structure design to facilitate fine-tuning of the height through rotation. The bottom of the fine-tuning wheel 19 is threadedly connected to the top of the limiting plate 3. The threaded connection has self-locking properties, which can keep the position stable after fine-tuning. A level bubble 20 is fixedly connected to the bottom of the outer wall of the tank 4. The level bubble 20 serves as a level indicator element, allowing operators to visually observe the level status of the tank 4. The top of the fine-tuning wheel 19 is rotatably connected to the bottom of the tank 4. The rotatable connection method ensures that the tank 4 will not rotate with the fine-tuning wheel 19 when it rotates, thus ensuring the stability of the tank 4 during the adjustment process.

[0024] Reference Figure 1 , Figure 3 , Figure 4The limiting assembly includes a limiting frame 14, which provides a mounting and protective shell for other components of the limiting assembly. The limiting frame 14 is fixedly connected to the outer arc surface of the disc 8. The inner wall of the limiting frame 14 is elastically connected to a limiting block 16 via a limiting spring 15. The limiting spring 15 provides elastic restoring force to the limiting block 16, ensuring that the limiting block 16 always tends to move downwards. A limiting rod 17 is fixedly connected to the top of the limiting block 16, allowing the operator to pull the limiting block 16 upwards to release the limit. A limiting groove 18 is formed on the top of the mounting base 1, and the limiting groove 18 is connected to the limiting block 16. The matching mechanism is used to position the disc 8. One end of the limiting spring 15 is fixedly connected to the inner wall of the limiting frame 14, and the other end of the limiting spring 15 is fixedly connected to the top of the limiting block 16. Through the opposing pressing force between the limiting spring 15 and the limiting frame 14, the limiting block 16 is always locked onto the inner wall of the limiting groove 18 without being affected by external forces. The bottom of the limiting frame 14 is in contact with the top of the mounting base 1. The limiting block 16 is slidably connected to the inner wall of the limiting frame 14. The limiting rod 17 is slidably connected to the top inner wall of the limiting frame 14. The limiting block 16 is locked onto the inner wall of the limiting groove 18.

[0025] Working principle: When installing the monitoring device, first, firmly install the mounting base 1 on the surface of the bridge pier to ensure the stability of the entire device. Then, by pulling the limiting rod 17 upward, the limiting block 16 is disengaged from the limiting groove 18, allowing the disc 8 to rotate freely. The rotation of the disc 8 drives the sliding rod 10 in the arc groove 9 to move, which in turn pushes the locking block 12 along the inner wall of the mounting disc 2 and retracts into the mounting disc 2 via the slider 11. Then, the tank 4 and the bottom limiting disc 3 are inserted into the top of the mounting disc 2. Next, the limiting rod 17 is moved in the opposite direction to drive the disc 8 to rotate. The arc groove 9 at the top of the disc 8 squeezes the sliding rod 10 to move, which in turn drives the slider 11 to push the locking block 12 along the sliding groove 13 and engage with the inner wall of the locking groove 7. Then, the limiting rod 17 is released, and the limiting block 16 is engaged with the limiting groove 18 under the action of the limiting spring 15, fixing the disc 8 and making the locking block 12 tightly engaged with the locking groove 7 on the outer wall of the limiting disc 3, thus completing the installation and fixing of the limiting disc 3 and the mounting disc 2.

[0026] Next, the operator observes the horizontal bubble 20 at the bottom of the outer wall of tank 4 to determine the levelness of tank 4 based on the bubble's position. If tank 4 is not level, the fine-adjustment wheel 19 is rotated using a tool. Since the bottom of the fine-adjustment wheel 19 is threadedly connected to the limit plate 3, its height changes during rotation, thus adjusting the levelness of tank 4. During the adjustment process, the horizontal bubble 20 is continuously observed until it is centered, ensuring that tank 4 is precisely level, thus guaranteeing accurate measurement by displacement gauge 5. When the bridge pier experiences settlement displacement, this displacement is transmitted to tank 4 sequentially through mounting base 1, mounting plate 2, and limit plate 3. The displacement of tank 4 causes the sensitive element inside displacement gauge 5 to actuate. Based on the principle of electromagnetic induction, displacement gauge 5 converts the displacement change into an electrical signal. After amplification, filtering, and analog-to-digital conversion by the internal signal processing circuit, it is converted into a digital signal and transmitted in real time to the data acquisition and processing center via wired or wireless transmission.
