Abstract
Description
Technical Field
[0001] The present application relates to the technical field of monitoring equipment, and in particular to a railway subgrade settlement and deformation monitoring device. Background Art
[0002] Railway subgrades are a crucial component of railway infrastructure, providing a solid foundation for tracks and ensuring safe and smooth train operation. Subgrade settlement and deformation are common problems in railway engineering, severely impacting safe railway operations. Therefore, it's essential to install monitors on the subgrade to monitor settlement in real time. If an anomaly occurs, timely action can be taken to address it and ensure safe train operation.
[0003] When installing the monitor, it needs to be kept horizontal to ensure the accuracy of the monitoring data. However, since the soil on some railway sections is relatively soft, although the monitor is initially installed horizontally, it may tilt due to its own gravity or environmental factors, resulting in inaccurate monitoring data.
[0004] In view of this, the purpose of the present invention is to provide a railway subgrade settlement deformation monitoring device with a warning function, which can issue a warning when the monitor tilts so that the staff can readjust the monitor to a horizontal level in time. Utility Model Content
[0005] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below. The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.
[0006] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a railway roadbed settlement and deformation monitoring device, including a base box and a monitor, a first universal seat is fixedly installed on the base box, a first universal ball is movably arranged in the first universal seat, and the monitor is fixed on the first universal ball; a second universal seat is arranged below the first universal ball, a second universal ball is movably arranged in the second universal seat, the bottom of the second universal ball is fixedly connected to a plumb bob, a pressure rod is fixedly arranged on the top of the second universal ball, and a pressure sensor is fixedly arranged on the bottom of the first universal ball. When the monitor is in a horizontal state, the pressure rod contacts the pressure sensor.
[0007] During operation, due to the provision of the first universal seat and the first universal ball, the monitor can be adjusted to a horizontal state by rotating the first universal ball; due to the provision of the second universal ball and the plumb bob, when the base box is tilted, the plumb bob can drive the second universal ball to rotate under the action of gravity, thereby adjusting the position of the second universal ball. Since a pressure rod is provided at the top of the second universal ball and a pressure sensor is provided at the bottom of the first universal ball, when the second universal ball rotates, the pressure rod will disengage from the pressure sensor, thereby causing the pressure sensor to transmit a signal to the staff, alerting the staff to readjust the monitor to a horizontal state.
[0008] Furthermore, the weight of the plumb bob is greater than the sum of the weights of the second universal ball and the pressure rod.
[0009] Furthermore, a first universal groove with an open top surface and a bottom surface is formed on the first universal seat, and the first universal ball is movably disposed in the first universal groove;
[0010] The side wall portion of the first universal seat penetrates into the first universal groove to form a limiting groove, and a limiting block is movably provided in the limiting groove;
[0011] A side plate is fixedly arranged on the base box, a limiting screw is threadedly connected to the side plate, and the limiting screw is fixedly connected to the limiting block.
[0012] Furthermore, the base plate is fixedly mounted on the inner wall of the base box, the second universal seat is fixedly arranged on the base plate, a second universal groove with top and bottom openings is formed on the second universal seat, and the second universal ball is movably arranged in the second universal groove.
[0013] Furthermore, a semicircular interference portion is formed on the top of the pressure rod.
[0014] Furthermore, an adjusting rod is fixedly installed on the bottom surface of the base box, and a conical soil rod is threadedly connected to the adjusting rod, and the bottom of the conical soil rod forms a conical taper portion.
[0015] Furthermore, an anti-sinking plate is fixedly arranged on the cone soil rod.
[0016] Furthermore, an opening and closing door is installed on the side of the base box through a hinge.
[0017] The beneficial effects of this application are:
[0018] 1. When the base box tilts, the second universal ball will rotate under the action of the plumb bob, thereby driving the pressure rod to rotate, so that the pressure rod and the pressure sensor are out of conflict, thereby alerting the staff to readjust the monitor to a horizontal state.
[0019] 2. The setting of the limit block can fix the position of the first universal ball to prevent the monitor from shaking due to external factors.
[0020] 3. The setting of the resistance part can improve the accuracy of the resistance between the pressure sensor and the pressure rod. Only when the monitor is kept horizontal can the pressure rod resist the pressure sensor.
[0021] Fourth, the setting of the cone-in part makes it easy to fix the base box in the soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.
[0039] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".
[0040] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0041] A railway subgrade settlement and deformation monitoring device includes a base box 1 and a monitor 2. A first universal seat 3 is fixedly mounted on the base box 1. A first universal ball 301 is movably disposed within the first universal seat 3. The first universal ball 301 has two mutually parallel top and bottom surfaces. The top surface of the first universal ball 301 is fixedly connected to a support rod 302. A mounting plate 303 is fixedly disposed at the top end of the support rod 302. The monitor 2 is fixedly mounted on the mounting plate 303.
[0042] Specifically, the first universal seat 3 is fixedly connected to the top surface of the base box 1 by bolts; the top surface portion of the first universal seat 3 penetrates the first universal seat 3 to form a first universal groove 304 with openings on the top and bottom surfaces; the first universal ball 301 is movably disposed in the first universal groove 304; by rotating the first universal ball 301, the monitor 2 can be adjusted to a horizontal state;
[0043] In order to fix the position of the first universal ball 301 and prevent the monitor 2 from shaking due to external force after being adjusted to the horizontal position, the side wall portion of the first universal seat 3 penetrates into the first universal groove 304 to form a limit groove 305, and a limit block 306 is movably set in the limit groove 305; a side plate 308 is fixedly set on the top wall of the base box 1, and a limit screw 307 is threadedly connected to the side plate 308, and the limit screw 307 is fixedly connected to the limit block 306; by rotating the limit screw 307, the limit block 306 can be rotated and moved in the limit groove 305, and after the limit block 306 moves, it can conflict with the first universal ball 301, thereby fixing the position of the first universal ball 301.
[0044] Since the base box 1 may sink into the soil due to its own gravity, or tilt due to the influence of the external environment; when the base box 1 tilts, the position of the monitor 2 will also change, thereby affecting the accuracy of the monitoring value of the monitor 2;
[0045] In order to solve the above problem, a base plate 102 is fixedly installed on the inner wall of the base box 1, and a second universal seat 4 is fixedly installed on the base plate 102 by bolts. The top surface of the second universal seat 4 passes through the second universal seat 4 to form a second universal groove 401 with openings on the top and bottom surfaces. The second universal ball 402 is movably arranged in the second universal groove 401. Two mutually parallel top and bottom surfaces are formed on the second universal ball 402. The bottom surface of the second universal ball 402 is fixedly connected to the plumb block 403. A pressure rod 404 is fixedly installed on the top surface of the second universal ball 402. A semicircular interference portion 405 is formed on the top of the pressure rod 404. The pressure sensor 5 is fixedly installed on the bottom surface of the first universal ball 301. When the top surfaces of the first universal ball 301 and the second universal ball 402 are parallel to each other, that is, when the monitor 2 is in a horizontal state, the pressure rod 404 can interfere with the pressure sensor 5, otherwise it is out of interference.
[0046] It should be noted that the weight of the plumb bob 403 is greater than the sum of the weights of the second universal ball 402 and the pressure rod 404. When the base box 1 is tilted, the second universal ball 402 can always rotate until the top surface is in a horizontal state under the action of the plumb bob 403; when the second universal ball 402 rotates and drives the pressure rod 404 to rotate, the pressure rod 404 will disengage from the pressure sensor 5, so that the pressure sensor 5 can transmit a signal to the staff, alerting the staff to readjust the monitor 2 to a horizontal state.
[0047] In order to facilitate the fixing of the base box 1, four adjusting rods 104 are fixedly installed on the bottom surface of the base box 1 near the four corners. The adjusting rods 104 are threadedly connected to the tapered soil rods 105. The bottom of the tapered soil rods 105 forms a conical cone-shaped cone-entry portion 106, which is convenient for the cone to penetrate into the soil, thereby fixing the base box 1. The adjusting rods 104 are threadedly connected to the tapered soil rods 105, which can facilitate the adjustment of the base box 1 to a nearly horizontal level on an uneven ground. Anti-sinking plates 107 are fixedly provided on the tapered soil rods 105. The anti-sinking plates 107 can increase the contact area between the tapered soil rods 105 and the ground surface, preventing the tapered soil rods 105 from sinking into the soil;
[0048] In order to facilitate the installation of the internal structure of the base box 1, an opening and closing door 108 is installed on the side of the base box 1 through a hinge. The setting of the opening and closing door 108 can also facilitate the staff to adjust the position of the first universal ball 301. A handle 109 is fixed on the opening and closing door 108 for easy manual opening.
[0049] The specific working principle is as follows:
[0050] Fix the base box 1 at the monitoring point. Since a plumb bob 403 is provided at the bottom of the second universal ball 402, the second universal ball 402 can always rotate under the action of the plumb bob 403 until the top surface of the second universal ball 402 remains horizontal. At this time, manually rotate the first universal ball 301 until the pressure sensor 5 contacts the pressure rod 404 on the second universal ball 402. Then the top and bottom surfaces of the first universal ball 301 are parallel to the top surface of the second universal ball 402. At this time, the monitor 2 remains horizontal. The rotation limit The positioning screw 307 causes the limit block 306 to contact the first universal ball 301, thereby fixing the position of the first universal ball 301, thereby fixing the position of the monitor 2; when the base box 1 tilts due to its own gravity or external influences, the second universal ball 402 will drive the pressure rod 404 to rotate under the action of the plumb bob 403, so that the pressure rod 404 is out of contact with the pressure sensor 5, so that the pressure sensor 5 can transmit a signal to the staff, alerting the staff to readjust the monitor 2 to a horizontal state.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
