Description

Technical Field

[0001] This utility model relates to the field of subway settlement monitoring technology, and in particular to a surface settlement monitoring device near an existing subway line. Background Technology

[0002] When monitoring ground subsidence along subway lines, a ground subsidence monitoring device located near existing subway lines is often used. This device can monitor ground subsidence in real time and accurately, detect potential safety hazards in advance, ensure the safety of subway operations, reduce the impact on the surrounding environment, and provide data support for the maintenance and optimization of subway facilities. This device typically includes sensors, data acquisition and transmission systems, etc. It uses high-precision measurement technology to sense minute changes in the ground surface and provide timely feedback. This device is used because ground subsidence near existing subway lines can affect the structural safety of the subway and cause problems such as track deformation. Real-time monitoring can effectively prevent accidents and ensure the stable operation of urban rail transit.

[0003] Monitoring of surface subsidence near existing subway lines mainly involves installing high-precision sensors in key areas near the subway lines to collect surface subsidence data in real time. The data is then transmitted wirelessly to the monitoring center, where professional software is used to analyze and process the data. Once an abnormal subsidence trend is detected, an early warning mechanism is immediately activated to notify relevant departments to take measures. Simultaneously, monitoring continues until the subsidence stabilizes to ensure the safety of subway operations.

[0004] Existing technologies for surface settlement monitoring devices near existing subway lines rely on traditional leveling methods. While simple in principle, these methods are inefficient and susceptible to human error, making rapid and accurate monitoring of large areas difficult. Furthermore, they lack real-time data acquisition, resulting in delayed feedback on settlement changes and hindering timely early warnings for subway operation safety. While total station-based monitoring solutions offer improved accuracy, their monitoring range is limited, and the equipment is expensive and complex to install and maintain, making them uneconomical and impractical for long-distance subway line surface monitoring. Additionally, existing remote monitoring methods suffer from data transmission stability and reliability issues, are susceptible to environmental interference leading to data loss or errors, and fail to provide subway operators with continuous and accurate surface settlement information. Therefore, this paper proposes a surface settlement monitoring device for use near existing subway lines to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a surface subsidence monitoring device near an existing subway line, aiming to improve the problem that some existing devices cannot monitor surface subsidence of subway lines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A surface subsidence monitoring device near an existing subway line includes a mounting base. Two drive boxes are fixedly connected to the left and right sides of the top central space area of ​​the two mounting bases. An adjustment mechanism is provided inside the two drive boxes, and a monitoring mechanism is provided on the left and right sides of the outer wall of the drive boxes.

[0008] The adjustment mechanism includes a drive box, and drive components are fixedly connected to the left and right sides of the internal space area of ​​the two drive boxes. A connecting rod is slidably connected to the drive end of the drive component. A connecting plate is fixedly connected to the left and right sides of the outer wall of the connecting rod. A guide sleeve is fixedly connected to the left and right sides of the outer wall of the connecting plate. A sliding groove is opened on the left and right sides of the internal space area of ​​the guide sleeve. A monitoring slider is slidably connected to the left and right sides of the internal space area of ​​the sliding groove. A connecting shaft is fixedly connected to the left and right sides of the outer wall of the monitoring slider. A connecting bracket is fixedly connected to the left and right sides of the outer wall of the connecting shaft.

[0009] As a further description of the above technical solution:

[0010] The monitoring mechanism includes an infrared ranging probe. Two monitors are fixedly connected to the left and right sides of the top space area of ​​the connecting bracket. The top left and right sides of the infrared ranging probe are fixedly connected to the bottom left and right sides of the connecting bracket.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes a cylinder, the cylinder being externally fixedly connected to the inside of the drive housing, and the connecting rod being externally fixedly connected to the inside of the cylinder.

[0013] As a further description of the above technical solution:

[0014] The top left and right sides of the monitor are fixedly connected to a ring support frame, and the top space area of ​​the ring support frame is fixedly connected to an adjustment trigger.

[0015] As a further description of the above technical solution:

[0016] The top space region of the adjustment trigger is fixedly connected to a top plate, and the left and right sides of the space region of the outer wall of the top plate are fixedly connected to the left and right sides of the space region inside the annular support frame.

[0017] As a further description of the above technical solution:

[0018] Movable doors are fixedly connected to the left and right sides of the space area in the outer wall of the drive box, and a handle is fixedly connected to one side of the outer wall of the movable door;

[0022] Screws are fixedly connected to the left and right sides of the space area in the outer wall of the drive box, and the bottom side of the screws is fixedly connected to the top of the mounting base.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a cylinder causes a connecting rod to move a connecting plate. The movement of the connecting plate causes a guide sleeve to move a monitoring slider. The monitoring slider then moves a connecting bracket via a connecting shaft. The movement of the connecting bracket causes a ring support frame to move a monitor, thereby adjusting the monitor so that the adjustment trigger can make good contact with the detection tunnel, ensuring that the overall structure meets the usage requirements.

The deformation force will be transmitted to the monitoring sliders at the left and right ends of the annular support frame. The monitoring sliders will slide laterally to both sides under the force, so that the infrared ranging probe can provide feedback on the change of the monitoring distance data between the two sides. It can also intuitively observe the tunnel settlement, making the monitoring more comprehensive and complete, and with higher accuracy. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1 to 2 The present invention provides an embodiment of a surface settlement monitoring device near an existing subway line, comprising a mounting base 1, which serves as the basic support component of the entire surface settlement monitoring device. The mounting base 1 bears the weight of components such as the drive box 2, the adjustment mechanism, and the monitoring mechanism, and evenly transfers these weights to the ground surface to ensure that the device remains stable during operation. At the same time, it also provides a fixed installation position for the device, enabling the monitoring device to accurately monitor surface settlement in a specific area.

[0034] Two drive boxes 2 are fixedly connected to the left and right sides of the top space area of ​​the two mounting bases 1. This provides a relatively independent and stable working environment for the adjustment mechanism, protecting the precision components inside the adjustment mechanism from the influence of the external environment. At the same time, the drive boxes 2 also support and fix the adjustment mechanism, enabling the adjustment mechanism to run smoothly inside and realize the position adjustment of components such as the monitoring slider 8. The adjustment mechanism is set inside the two drive boxes 2, and the monitoring mechanism is set on the left and right sides of the outer wall of the drive boxes 2.

[0035] The adjustment mechanism includes a drive box 2. Drive components are fixedly connected to the left and right sides of the internal space area of ​​the two drive boxes 2 to provide power for the entire adjustment process. The cylinder 3 can realize the extension and retraction of the connecting rod 4, thereby driving the monitoring slider 8 to slide in the slide groove 7, and thus adjusting the position of the monitoring mechanism to adapt to different monitoring needs. The drive end of the drive component is slidably connected to the connecting rod 4, which transmits the power output by the drive component to the connecting plate 5 and drives the connecting plate 5 to make linear motion.

[0036] Connecting plates 5 are fixedly connected to the left and right sides of the outer wall of the connecting rod 4, which converts the linear motion of the connecting rod 4 into the sliding motion of the monitoring slider 8 in the slide groove 7. Through cooperation with the guide sleeve 6, the monitoring slider 8 can move linearly in the direction perpendicular to the ground, thereby realizing accurate monitoring of the ground subsidence. The guide sleeve 6 is fixedly connected to the left and right sides of the outer wall of the connecting plate 5, which provides accurate guidance for the movement of the monitoring slider 8, ensuring that the monitoring slider 8 can only move linearly in the vertical direction, avoiding the displacement or shaking of the monitoring slider 8 caused by external interference or other factors, thereby improving the accuracy and reliability of the monitoring data.

[0037] The guide sleeve 6 has grooves 7 on the left and right sides of the internal space area, which provide a track for the movement of the monitoring slider 8 and restrict the movement direction of the monitoring slider 8, so that it can only move in a straight line along the vertical direction. At the same time, the grooves 7 can also reduce the friction of the monitoring slider 8 during the movement, reduce energy loss, and improve the working efficiency of the monitoring device. The monitoring slider 8 is slidably connected to the left and right sides of the internal space area of ​​the groove 7. It is a component that directly contacts the ground surface and senses the amount of ground subsidence. When the ground subsides, the monitoring slider 8 will sink with the ground surface. Its displacement change in the groove 7 reflects the amount of ground subsidence. Through cooperation with the connecting shaft 9, connecting bracket 10 and other components, the amount of ground subsidence is transmitted to the monitoring agency for measurement and recording.

[0038] Connecting shafts 9 are fixedly connected to the left and right sides of the outer wall of the monitoring slider 8, connecting the monitoring slider 8 and the connecting bracket 10 together to form a stable mechanical structure. This structure can transmit the force generated when the monitoring slider 8 slides in the slide groove 7 to the connecting bracket 10, so that the connecting bracket 10 can move synchronously with the movement of the monitoring slider 8, thereby ensuring the normal operation of the entire monitoring device. Connecting brackets 10 are fixedly connected to the left and right sides of the outer wall of the connecting shaft 9, serving as a bridge between the monitoring slider 8 and the monitoring mechanism. This structure converts the movement of the monitoring slider 8 into a measurement signal for the monitoring mechanism. When the monitoring slider 8 slides in the slide groove 7, the connecting bracket 10 will move accordingly, thereby driving the monitoring mechanism to monitor the surface subsidence in real time.

[0039] The monitoring mechanism includes an infrared ranging probe 11, which is one of the core components of the monitoring mechanism. It monitors the subsidence of the ground by measuring the change in the distance between the probe and the ground surface. When the ground surface subsides, the distance between the probe and the ground surface will change accordingly. The infrared ranging probe 11 can detect this change in real time and convert it into an electrical signal to be transmitted to the subsequent processing unit for analysis and processing.

[0040] Two monitors 12 are fixedly connected to the left and right sides of the top central space area of ​​the connecting bracket 10. These monitors process and display the data measured by the infrared ranging probe 11. They can receive the signals transmitted from the infrared ranging probe 11 in real time, and after analysis and processing, display the amount of ground subsidence on the screen in the form of numbers or graphics. At the same time, the monitors 12 can also store the monitoring data for subsequent query and analysis. The top left and right sides of the infrared ranging probe 11 are fixedly connected to the bottom left and right sides of the connecting bracket 10.

[0041] Reference Figures 2 to 3 The drive assembly includes a cylinder 3, which is externally fixedly connected to the inside of the drive box 2. The connecting rod 4 is externally fixedly connected to the inside of the cylinder 3. The top left and right sides of the monitor 12 are fixedly connected to annular support frames 13, which mainly serve to support and fix the monitor 12. By mounting the monitor 12 on the annular support frame 13, it can be ensured that it will not shake or shift due to external interference during operation, thus ensuring the accuracy and reliability of the monitoring data. At the same time, the annular support frame 13 can also distribute the weight of the monitor 12 components, reduce the pressure on a single connection point, and improve the stability of the entire device.

[0042] An adjustment trigger 14 is fixedly connected to the top space of the ring support frame 13. It is used to trigger and control the adjustment action. When it is necessary to adjust the parameters of the land subsidence monitoring device, the operator can operate the adjustment trigger 14 to issue a command to drive the corresponding adjustment mechanism to work. For example, when it is necessary to change the position of the monitoring slider 8 or adjust the measurement range of the monitoring mechanism, the adjustment trigger 14 can start the drive component to make the relevant parts move according to the preset program, thereby achieving precise adjustment of the device.

[0043] The top space area of ​​the adjustment trigger 14 is fixedly connected to the top plate 15, which fixes the monitor 12 component on it to prevent tilting or shaking during use. At the same time, the top plate 15 can also serve as a transition component connecting the annular support frame 13 and the monitor 12, so as to evenly transmit the supporting force of the annular support frame 13 to the monitor 12 and ensure the normal operation of the monitor 12. The left and right sides of the outer wall space area of ​​the top plate 15 are fixedly connected to the left and right sides of the inner space area of ​​the annular support frame 13.

[0044] Reference Figures 3 to 4Movable doors 16 are fixedly connected to the left and right sides of the space area in the outer wall of the drive box 2. This facilitates the operator to inspect and maintain the internal components of the drive box 2. When it is necessary to inspect, repair or replace the adjustment mechanism or sensor components inside the drive box 2, the operator can open the movable doors 16 to operate the internal components directly. At the same time, the movable doors 16 can also protect the internal components of the drive box 2 and prevent dust, debris and other objects from entering the drive box 2 and affecting the normal operation of the device.

[0045] A handle 17 is fixedly connected to one side of the outer wall of the movable door 16, providing a convenient operating interface for the operator, allowing the operator to easily open and close the movable door 16. When opening the movable door 16, the operator only needs to hold the handle 17 and apply appropriate force to open the movable door 16. When closing the movable door 16, the operator also closes and locks the movable door 16 by using the handle 17. A display 18 is fixedly connected to one side of the outer wall of the drive box 2, used to display the working status, monitoring data and related information of the monitoring device in real time. It can intuitively display the ground settlement measured by the monitor 12 to the operator in the form of numbers, charts or curves, so that the operator can understand the ground settlement situation in a timely manner. At the same time, the display 18 can also display the device's fault alarm information, parameter setting interface, etc.

[0046] Fixing rods 20 are fixedly connected to the left and right sides of the internal space area of ​​the mounting base 1 to firmly fix the drive box 2 to the mounting base 1, preventing the drive box 2 from shaking or shifting during use. Through the connection with the mounting base 1 and the drive box 2, a stable support structure is formed to ensure the normal operation of the entire device. Fixing rods 20 are fixedly connected to the left and right sides of the internal space area of ​​the outer wall of the drive box 2 to connect the drive box 2 and the mounting base 1, and to firmly fix the drive box 2 to the mounting base 1. During the installation process, screws 19 are passed through the screw holes on the mounting base 1, and then tightened with nuts or screwdrivers to make the mounting base 1 tightly connected together. The bottom side of the fixing rod 20 is fixedly connected to the top of the mounting base 1.

[0047] Working principle: Cylinder 3 starts in drive box 2 and transmits power to connecting plate 5 through connecting rod 4. Connecting plate 5 cooperates with guide sleeve 6 to make monitoring slider 8 move in a straight line in vertical direction in slide groove 7. When the ground settles, monitoring slider 8 sinks with the ground and its displacement changes reflect the amount of ground settlement. Connecting shaft 9 connects monitoring slider 8 to connecting bracket 10 to form a stable mechanical structure. The force generated by the sliding of monitoring slider 8 in slide groove 7 is transmitted to connecting bracket 10. The movement of connecting bracket 10 drives the monitoring mechanism to monitor and record the amount of ground settlement in real time.

[0048] During operation, when the ground subsides, the monitoring slider 8 sinks accordingly. Its displacement change is transmitted to the connecting bracket 10 through the connecting shaft 9. The connecting bracket 10 drives the monitoring mechanism to work. The infrared ranging probe 11 measures the change in distance from the ground surface and transmits the signal to the monitor 12. The monitor 12 processes the data and displays it on the screen in real time. It can also store the data. The operator can adjust the position of the monitoring slider 8 or the measurement range of the monitoring mechanism by adjusting the trigger 14. The movable door 16 of the drive box 2 facilitates inspection and maintenance. The display 18 on its outer wall can display the working status of the device, monitoring data and related information, realizing accurate monitoring of the ground subsidence of the adjacent existing subway line.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
