[0002] In the field of rail transit, accurately understanding the vibration and displacement of rails when trains pass is crucial for ensuring track structural stability, train operation safety, and improving passenger comfort. To achieve a systematic assessment of rail vibration and displacement, the actual testing process needs to simultaneously acquire data on the horizontal and vertical relative displacements between the rails and sleepers, thereby jointly reflecting the stress characteristics and deformation state of the track.

[0003] In related technologies, it is generally necessary to configure two independent testing devices to separately test the horizontal and vertical relative displacements of the rails.

[0040] See Figure 1 The diagram shows a schematic of the installation structure of a track displacement detection device 10 according to an embodiment of this application. The track displacement detection device 10 provided in this embodiment includes an installation mechanism 100, a horizontal displacement detection component 200, and a vertical displacement detection component 300. The installation mechanism 100 is used to install on a sleeper 30. The horizontal displacement detection component 200 and the vertical displacement detection component 300 are used to detect the horizontal and vertical displacements of the track 20 on the sleeper 30, respectively. The track 20 generally refers to a steel rail. It should be noted that the horizontal direction in this text refers to the Y direction in the figure, i.e., the width direction of the track 20, and the vertical direction refers to the Z direction in the figure, i.e., the height direction of the track 20. Horizontal displacement refers to displacement along the Y direction, and vertical displacement refers to displacement along the Z direction.

[0041] The mounting mechanism 100 includes a first mounting assembly 110 and a second mounting assembly 120 connected to each other. The first mounting assembly 110 and the second mounting assembly 120 are respectively used to mount the horizontal displacement detection component 200 and the vertical displacement detection component 300. Specifically, the first mounting assembly 110 has a straight first mounting channel 111, and the second mounting assembly 120 has a straight second mounting channel 121. The first mounting channel 111 and the second mounting channel 121 are perpendicular to each other. Exemplarily, the first mounting channel 111 extends horizontally, and the second mounting channel 121 extends vertically.

[0042] A horizontal displacement detection component 200 is disposed within the first mounting channel 111, and is configured to detect the horizontal displacement of the track 20. Exemplarily, the horizontal displacement detection component 200 can be a horizontal displacement sensor, which is mounted within the first mounting channel 111 and used to detect the displacement of the track 20 along the Y direction. Figure 1 As shown, after the horizontal displacement sensor is installed, the sensor's pin is in close contact with the web surface of the rail 20.

[0043] A vertical displacement detection component 300 is disposed within the second mounting channel 121. The vertical displacement detection component 300 is configured to detect the displacement of the track 20 along the vertical direction. Exemplarily, the vertical displacement detection component 300 can be a vertical displacement sensor, which is mounted within the second mounting channel 121 and used to detect the displacement of the track 20 along the Z direction. Figure 1 As shown, after the vertical displacement sensor is installed, the sensor's pin is in close contact with the upper surface of the rail base of track 20, enabling the sensor's pin to accurately capture the vibration displacement of track 20, thereby achieving accurate data acquisition.

[0044] With the above structural design, during use, the horizontal displacement detection component 200 and the vertical displacement detection component 300 can be simultaneously fixed to the first mounting assembly 110 and the second mounting assembly 120 of the mounting mechanism 100, respectively, so that the pin of the horizontal displacement detection component 200 is in close contact with the side of the rail web of the track 20, and the pin of the vertical displacement detection component 300 is in close contact with the upper surface of the rail bottom of the track 20. At this time, the pins of the horizontal displacement detection component 200 and the vertical displacement detection component 300 can accurately capture the vibration displacement of the track 20, thereby realizing the simultaneous measurement of the relative horizontal and vertical displacements between the track 20 and the sleeper 30.

[0045] Therefore, the track displacement detection device 10 of this application embodiment can achieve synchronous detection of horizontal and vertical displacements by integrating the horizontal displacement detection component 200 and the vertical displacement detection component 300 into the same mounting mechanism 100. This also significantly reduces the overall space occupied by the device, lowers the purchase cost, and simplifies the installation and commissioning process. Furthermore, the track displacement detection device 10 only needs to be installed above the sleeper 30, and can simultaneously meet the testing needs of both the horizontal and vertical displacements of the rails relative to the sleeper 30 in ballasted and ballastless tracks 20.

[0046] See Figures 1 to 3 As shown, in some embodiments, the mounting mechanism 100 further includes a support component 130, to which both the first mounting component 110 and the second mounting component 120 are connected. The support component 130 provides a stable connection base for the first mounting component 110 and the second mounting component 120, preventing relative displacement between them when the track 20 vibrates, ensuring consistency of the reference for horizontal and vertical displacement detection, and improving the reliability of the detection data. Furthermore, by fixing the support component 130 to the sleeper 30, the installation and positioning of the entire track displacement detection device 10 becomes more convenient. Only the support component 130 needs to be fixed to achieve synchronous installation of the horizontal displacement detection component 200 and the vertical displacement detection component 300, reducing the alignment and adjustment steps of the two detection components.

[0047] Furthermore, in some embodiments, the support assembly 130 includes a support base 131 and a connector 132. The support base 131 is connected to the connector 132, which extends horizontally and is connected to the first mounting assembly 110 and the second mounting assembly 120, respectively.

[0048] Specifically, the bottom of the support base 131 fits snugly against the upper surface of the sleeper 30, ensuring convenient installation and a secure fixing method. For example, the lower surface of the support base 131 is glued to the upper surface of the sleeper 30. By adjusting the position and angle of the support base 131 on the sleeper 30, the pins of the horizontal displacement detection component 200 and the vertical displacement detection component 300 can be made to make close contact with the side of the rail web and the upper surface of the rail bottom of the track 20, respectively, thereby enabling accurate measurement of the vibration displacement of the track 20.

[0049] The connector 132 of the support assembly 130 is a horizontally extending elongated strip structure. One end of the connector 132 is vertically connected to the support base 131, for example, by welding. The other end of the connector 132 is connected to the first mounting assembly 110 and the second mounting assembly 120, respectively, for example, by welding or by bolts or clips. The length of the connector 132 can be adjusted according to the width of the track 20 to ensure that the first mounting assembly 110 and the second mounting assembly 120 correspond to the side and bottom surfaces of the track 20, respectively. As an intermediate support structure, the connector 132 integrates the horizontal displacement detection component 200 and the vertical displacement detection component into the same support system, forming a modular structure that facilitates on-site assembly and disassembly, and is particularly suitable for rapid adaptation to different track gauges or track 20 structures.

[0050] See Figures 1 to 4 As shown, in some embodiments, the first mounting assembly 110 includes a first horizontal mounting member 112 and a second horizontal mounting member 113. The first horizontal mounting member 112 is connected to the support assembly 130, and the second horizontal mounting member 113 is detachably connected to the first horizontal mounting member 112. Exemplarily, both the first horizontal mounting member 112 and the second horizontal mounting member 113 are flat plate structures extending horizontally, i.e., both are perpendicular to the Z-direction. One side of the first horizontal mounting member 112 is welded to the connector 132 of the support assembly 130. Both the first horizontal mounting member 112 and the second horizontal mounting member 113 are provided with two screw holes, allowing for a detachable connection between the first horizontal mounting member 112 and the second horizontal mounting member 113 through screw engagement with the screw holes. This detachable connection allows the second horizontal mounting member 113 to be disassembled separately for the installation and replacement of the horizontal displacement detection component 200, which helps reduce maintenance costs and time.

[0051] The first horizontal mounting member 112 has a first horizontal mounting groove 112a on the side facing the second horizontal mounting member 113, and the second horizontal mounting member 113 has a second horizontal mounting groove 113a on the side facing the first horizontal mounting member 112. The first horizontal mounting groove 112a and the second horizontal mounting groove 113a together form a first mounting channel 111. The second horizontal mounting member 113 covers the first horizontal mounting member 112, so that the first horizontal mounting groove 112a and the second horizontal mounting groove 113a are connected to form the first mounting channel 111. For example, the cross-section of the first mounting channel 111 can be rectangular or circular. Thus, by cooperating the first horizontal mounting groove 112a on the first horizontal mounting member 112 and the second horizontal mounting groove 113a on the second horizontal mounting member 113 to fix the horizontal displacement detection component 200, accurate positioning and reliable fixation of the horizontal displacement detection component 200 can be achieved, ensuring the accuracy of the detection process. Furthermore, the first mounting channel 111 formed between the first horizontal mounting component 112 and the second horizontal mounting component 113 can effectively protect the internal horizontal displacement detection component 200 from external environmental interference such as dust and rainwater, thereby improving the durability and detection accuracy of the horizontal displacement detection component 200.

[0052] Optionally, in some embodiments, the depth of the first horizontal mounting groove 112a is the same as the depth of the second horizontal mounting groove 113a, ensuring that the horizontal displacement detection component 200 is installed in the center and avoiding detection errors caused by eccentricity. In some embodiments, the width of the first horizontal mounting groove 112a and the width of the second horizontal mounting groove 113a are the same as the width of the horizontal displacement detection component 200. The horizontal displacement detection component 200 can be fixed in the first mounting channel 111 formed by the first horizontal mounting groove 112a and the second horizontal mounting groove 113a by interference fit, preventing lateral movement during vibration, reducing detection errors, and ensuring the accuracy of horizontal displacement data.

[0053] See Figure 3 and Figure 4As shown, in some embodiments, the first horizontal mounting member 112 has a first plane 112b on the side away from the support assembly 130, and the second horizontal mounting member 113 has a second plane 113b on the side away from the support assembly 130. The first plane 112b and the second plane 113b are coplanar and parallel to the side surface of the track 20, where coplanar means located in the same plane. The extension direction of the first mounting channel 111 is perpendicular to the first plane 112b and the second plane 113b, that is, the extension direction of the first mounting channel 111 is perpendicular to the side surface of the track 20. The opening at the end of the first mounting channel 111 away from the support assembly 130 is coplanar with the first plane 112b and the second plane 113b, so that the detection probe of the horizontal displacement detection component 200 is flush with the side surface of the track 20, ensuring that the detection probe is in direct contact with the surface of the track 20, eliminating the detection delay caused by gaps, and providing more space for the installation and adjustment of the horizontal displacement detection component 200.

[0054] See Figures 1 to 4 , Figure 5 As shown, in some embodiments, the second mounting assembly 120 includes a first vertical mounting member 122 and a second vertical mounting member 123. The first vertical mounting member 122 is connected to the support assembly 130, and the second vertical mounting member 123 is detachably connected to the first vertical mounting member 122. Exemplarily, both the first vertical mounting member 122 and the second vertical mounting member 123 are flat plate structures extending in the vertical direction, i.e., both are perpendicular to the Y direction. One side of the first vertical mounting member 122 is welded to the connector 132 of the support assembly 130. Both the first vertical mounting member 122 and the second vertical mounting member 123 are provided with four screw holes, allowing for a detachable connection between the first vertical mounting member 122 and the second vertical mounting member 123 through screw engagement with the screw holes, facilitating the installation of the vertical displacement detection component 300.

[0055] The first vertical mounting member 122 is provided with a first vertical mounting groove 122a, and the second vertical mounting member 123 is provided with a second vertical mounting groove 123a. The first vertical mounting groove 122a and the second vertical mounting groove 123a together form a second mounting channel 121. The first vertical mounting member 122 has the first vertical mounting groove 122a facing the second vertical mounting member 123, and the second vertical mounting member 123 has the second vertical mounting groove 123a facing the first vertical mounting member 122. The first vertical mounting groove 122a and the second vertical mounting groove 123a together form a second mounting channel 121, which can realize accurate positioning and reliable fixation of the vertical displacement detection component 300, and ensure the accuracy of the detection process.

[0056] Optionally, in some embodiments, the depth of the first vertical mounting groove 122a is the same as the depth of the second vertical mounting groove 123a, and the widths of the first vertical mounting groove 122a and the second vertical mounting groove 123a are the same as the width of the vertical displacement detection component 300. Thus, the vertical displacement detection component 300 can be fixed within the second mounting channel 121 by an interference fit, preventing vertical and lateral movement during vibration, reducing detection errors, and ensuring the accuracy of the vertical displacement data.

[0057] See Figure 6 As shown, in some embodiments, the track displacement detection device 10 further includes a test signal preprocessing module 400. The test signal preprocessing module 400 includes a signal filtering submodule 410, a signal amplification submodule 420, and a signal conversion unit 430. The horizontal displacement detection component 200 and the vertical displacement detection component 300 are electrically connected to the signal filtering submodule 410 via data transmission lines. The signal filtering submodule 410, the signal amplification submodule 420, and the signal conversion unit 430 are sequentially electrically connected via data transmission lines. The displacement signals collected by the horizontal displacement detection component 200 and the signal amplification submodule 300 are sequentially filtered by the signal filtering submodule 410 (e.g., a low-pass filter) to remove high-frequency noise, amplified to a suitable voltage range by the signal amplification submodule 420 (e.g., an operational amplifier), and converted from analog signals to digital signals by the signal conversion unit 430 (e.g., an A / D converter). The accuracy of the acquired track 20 displacement data is further improved through the signal amplification submodule 420 and the signal filtering submodule 410. The analog signal obtained by the test is converted into a digital signal that can be directly read by the microcontroller 500 through the signal conversion unit 430, which facilitates the subsequent processing of the track 20 displacement data obtained by the test.

[0058] Continue reading Figure 6As shown, in some embodiments, the track displacement detection device 10 further includes a microcontroller 500, a display 600, and a data storage hard disk 700. The signal conversion unit 430 is electrically connected to the microcontroller 500, and the microcontroller 500 is electrically connected to both the display 600 and the data storage hard disk 700. Optionally, the track displacement detection device 10 also includes a power supply 800, such as a battery, which powers the horizontal displacement detection component 200, the vertical displacement detection component 300, the test signal preprocessing module 400, the microcontroller 500, and the display 600. The digital signal output by the signal conversion unit 430 is transmitted to the microcontroller 500 (e.g., an STM chip). The microcontroller 500 processes the data in real time and displays the results on the display 600 (e.g., an LCD touchscreen) and simultaneously stores them in the data storage hard disk 700. Therefore, after the horizontal and vertical displacement detection data of track 20 are processed by the microcontroller 500, the detection data can be displayed intuitively on the display 600, which facilitates the real-time observation of the detection signals by the inspection personnel. At the same time, the data storage hard disk 700 can realize the real-time storage of the detection data and support historical data query and long-term trend analysis, which facilitates the further organization and analysis of the detection data in the later stage and provides data support for the maintenance of track 20.
