Description

Technical Field

[0001] This invention relates to the field of stable operation, and in particular to a method for measuring track bed subsidence and related components. Background Technology

[0002] During the construction and maintenance of railway lines, tamping and stabilization systems are periodically used to eliminate track irregularities and restore ballast performance. The specific process of tamping and stabilization generally involves tamping the ballast on both sides of the rails to increase the density of the ballast at the bottom of the sleepers, eliminating track deviations and making the track smooth and stable. Simultaneously, the ballast at the bottom of the sleepers is further compacted to improve the overall stability of the railway line and ensure the safe high-speed operation of trains.

[0003] Stabilization systems are generally used in conjunction with tamping systems and include other railway operation devices such as the driver's cab and control box. Tamping systems typically include tamping cars, while stabilization systems typically include stabilization cars. However, due to the complexity of stabilization systems, involving the coordination of various railway operation devices, existing technologies lack reasonable and scientific methods for detecting and evaluating the results of stabilization system operations. This makes it difficult to control the quality of the ballast bed after stabilization operations and to accurately obtain the ballast bed condition after stabilization. Summary of the Invention

[0004] The purpose of this invention is to provide a method and related components for measuring the settlement of a track bed. This method measures the settlement of the track bed after it has been operating stably. The measurement process is real-time and efficient, the measurement results are accurate and reliable, and the measurement system has a simple structure and is easy to install.

[0005] To solve the above-mentioned technical problems, the present invention provides a method for measuring track bed settlement, applied to a stabilization system. The stabilization system includes a first measuring device, a second measuring device, and a third measuring device sequentially disposed at the bottom of the stabilization system. The first and second measuring devices are disposed at the front end of the stabilization device, and the third measuring device is disposed at the rear end of the stabilization device. The method for measuring track bed settlement includes:

[0006] Control the first measuring device, the second measuring device, and the third measuring device to fall onto the track;

[0007] Obtain the vertical displacement of the second measuring device after it is placed on the rail;

[0008] The subsidence of the third measuring device is determined based on the distance from the first measuring device to the second measuring device, the distance from the first measuring device to the third measuring device, and the vertical displacement.

[0009] Preferably, obtaining the vertical displacement of the second measuring device after it is placed on the rail includes:

[0010] The vertical displacement transmitted by the sensor installed in the second measuring device is acquired.

[0011] Preferably, the sensor is a pull-wire sensor.

[0012] Preferably, the subsidence of the third measuring device is obtained based on the distance from the first measuring device to the second measuring device, the distance from the first measuring device to the third measuring device, and the vertical displacement, including:

[0014] Since stabilization systems are often used in conjunction with tamping systems, the track is generally smooth after tamping. The settlement of the third measuring device is determined based on the vertical displacement, the length of the first chord, the length of the second chord, and the settlement relationship. The settlement relationship is as follows:

[0015] ;

[0016] Where a' is the subsidence amount, FA is the length of the first chord, EA is the length of the second chord, and a is the vertical displacement amount.

[0017] Preferably, after determining the subsidence of the third measuring device based on the distance from the first measuring device to the second measuring device, the distance from the first measuring device to the third measuring device, and the vertical displacement, the method further includes:

[0018] The subsidence amount is sent to the parameter recorder as the track bed subsidence amount after the operation of the stabilization system.

[0019] Preferably, after determining the subsidence of the third measuring device based on the distance from the first measuring device to the second measuring device, the distance from the first measuring device to the third measuring device, and the vertical displacement, the method further includes:

[0020] The mileage of the stabilization system is obtained by measuring the wheel located at the bottom of the stabilization system.

[0021] The mileage is sent to the parameter recorder.

[0022] The present invention also provides a track bed settlement measurement system, comprising:

[0023] The start-up module is used to control the first, second, and third measuring devices to be lowered onto the track.

[0026] The present invention also provides a stable system, comprising:

[0027] A first measuring device, a second measuring device, and a third measuring device are sequentially arranged at the bottom of the stabilization system. The first and second measuring devices are arranged at the front end of the stabilization device, wherein at least two measuring devices are arranged at the front end of the stabilization device, but not limited to two. The third measuring device is arranged at the rear end of the stabilization device, wherein at least one measuring device is arranged at the rear end of the stabilization device, but not limited to one.

[0029] A processor is used to execute the computer program to implement the steps of the track bed subsidence measurement method as described above.

[0030] The present invention also provides a computer-readable storage medium on which a computer program is stored, wherein the target computer program, when executed by a processor, implements the steps of the track bed subsidence measurement method described above.

[0031] This invention provides a method and related components for measuring track bed settlement. After the stabilization system stabilizes the railway track bed, the density of the ballast at the bottom of the sleepers increases, causing the track bed to settle compared to before the stabilization system operation. This invention utilizes the principle of similar triangles, and based on the distances from the first to the second and third measuring devices, and the vertical displacement of the second measuring device after it is lowered onto the rail, the settlement of the third measuring device after stabilization is obtained.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please refer to Figure 1 , Figure 1 A flowchart illustrating a method for measuring track bed settlement is provided in this embodiment of the invention. This method is applied to a stabilization system. Please refer to [the flowchart]. Figure 2 , Figure 2 This is a schematic diagram of a stabilization system provided in an embodiment of the present invention. The stabilization system is often used in conjunction with a tamping system. In this embodiment, the stabilization system 201 includes a tamping device 202 and a stabilization device 203, and further includes a first measuring device 204, a second measuring device 205, and a third measuring device 206 sequentially disposed at the bottom of the tamping stabilization system 201. The first measuring device 204 and the second measuring device 205 are disposed at the front end of the stabilization device 203, and the third measuring device 206 is disposed at the rear end of the stabilization device 203. The method for measuring the track bed settlement includes:

[0045] S101: Control the first measuring device 204, the second measuring device 205 and the third measuring device 206 to fall onto the track;

[0046] S102: Obtain the vertical displacement of the second measuring device 205 after it is placed on the rail;

[0047] S103: Determine the subsidence of the third measuring device 206 based on the distance from the first measuring device 204 to the second measuring device 205, the distance from the first measuring device 204 to the third measuring device 206, and the vertical displacement.

[0048] In a specific embodiment, upon receiving a start command, the stabilization system 201 begins stabilization operations. The first measuring device 204, the second measuring device 205, and the third measuring device 206 are lowered onto the rail, closely fitting together to begin measurement work. During the operation of the stabilization system 201 on the rail, the compaction of the ballast at the bottom of the railway sleepers increases, causing a corresponding subsidence in the track bed compared to before the stabilization system 201's operation. The vertical displacement of the second measuring device 205 after being lowered onto the rail is acquired in real time. Using the principle of similar triangles, based on the distances between the first and second measuring devices 204 and 205, and between the first and third measuring devices 204 and 206, and the vertical displacement, the subsidence of the third measuring device 206 is calculated in real time. This subsidence of the third measuring device 206 can be considered as the subsidence of the track bed.

[0049] It should be noted that the front end of the stabilizing device 203 in this example is not limited to only two measuring devices, the first measuring device 204 and the second measuring device 205, and the rear end of the stabilizing device 203 is not limited to only one measuring device, the third measuring device 206. For example, the front end of the stabilizing device 203 is equipped with three measuring devices, and the rear end of the stabilizing device 203 is equipped with two measuring devices. Any other setting scheme that can be implemented using the principle of this patent is acceptable.

[0050] It should be noted that the stabilization system 201 involved in this embodiment includes a tamping device 202 and a stabilization device 203, and may also include other necessary railway operation devices such as a driver's cab and a control box. In practical applications, the stabilization system 201 may also include an on-board industrial control computer, used to perform real-time calculations based on the distance from the first measuring device 204 to the second measuring device 205, the distance from the first measuring device 204 to the third measuring device 206, and the vertical displacement, to obtain the subsidence of the third measuring device 206; the stabilization system 201 may also include a parameter recorder, used to record important parameters during the measurement of the track bed subsidence, so that subsequent operators can evaluate the changes in the track condition. Among them, important parameters during the measurement process may include the mileage traveled by the stabilization system 201 during the stabilization operation, the subsidence of the third measuring device 206, etc.

[0051] Furthermore, this embodiment does not limit the specific placement of the first measuring device 204 and the second measuring device 205, as long as the first measuring device 204 is positioned before the second measuring device 205, on the same horizontal line as the third measuring device 206, and both are positioned before the third measuring device 206. Specifically, in some embodiments, the first measuring device 204 is positioned at the rear end of the tamping device 202, and the second measuring device 205 is positioned at the front end of the stabilizing device 203. In other embodiments, the first measuring device 204 is positioned at the front end of the stabilizing device 203, and the second measuring device 205 is positioned in the middle of the stabilizing device 203. In some embodiments, the stabilizing system 201 also includes a cab positioned in front of the tamping device 202, and the first measuring device 204 can also be positioned at the rear end of the cab. In some embodiments, the tamping device 202 is not positioned on the stabilizing system, or is not limited to the tamping device. The specific placement of the first measuring device 204 and the second measuring device 205 is not limited to the situations mentioned above and can be selected according to the actual situation.

[0052] This embodiment does not limit the specific method of obtaining the vertical displacement of the second measuring device 205 after it is placed on the rail. For example, the vertical displacement of the second measuring device 205 can be obtained by a sensor installed in the second measuring device 205, or by a height adjustment drive device connected to the second measuring device 205, or by other methods.

[0053] This invention provides a method for measuring track bed subsidence. After the stabilization system 201 performs stabilization work on the railway track bed, the density of the ballast at the bottom of the sleepers increases, causing the track bed to subside compared to before the stabilization system 201 operation. This invention utilizes the principle of similar triangles, and based on the distances from the first measuring device 204 to the second measuring device 205, the distance from the first measuring device 204 to the third measuring device 206, and the vertical displacement of the second measuring device 205 after its placement on the rail, the subsidence of the third measuring device 206 after stabilization is obtained. Since the first measuring device 204, the second measuring device 205, and the third measuring device 206 are all in close contact with the rail after placement, the subsidence of the third measuring device 206 after stabilization can be considered as the subsidence of the track bed after stabilization. The measurement process is real-time and efficient, the measurement results are accurate and reliable, the measurement system has a simple structure, and is easy to install.

[0054] Based on the above embodiments:

[0055] In a preferred embodiment, S102 obtains the vertical displacement of the second measuring device 205 after it is placed on the rail, including:

[0056] The vertical displacement transmitted by the sensor installed in the second measuring device 205 is acquired.

[0057] In a specific embodiment, when a start operation command is received, the second measuring device 205 is lowered onto the rail and fits tightly against the rail. After the stabilization system 201 performs stabilization work on the railway track bed, the density of the ballast at the bottom of the railway sleepers increases, and the track bed will sink accordingly compared to before the stabilization system 201 operation. The second measuring device 205, which is tightly fitted against the rail, sinks accordingly, generating a vertical displacement. The vertical displacement of the second measuring device 205 can be measured and obtained by the sensor installed in the second measuring device 205.

[0058] It should be noted that the front end of the stabilizing device 203 in this example is not limited to only two measuring devices, the first measuring device 204 and the second measuring device 205, and the rear end of the stabilizing device 203 is not limited to only one measuring device, the third measuring device 206. For example, the front end of the stabilizing device 203 is equipped with three measuring devices, and the rear end of the stabilizing device 203 is equipped with two measuring devices. Any other setting scheme that can be implemented using the principle of this patent is acceptable.

[0059] It should be noted that this embodiment does not limit the specific type of sensor installed in the second measuring device 205. For example, it can be a pull-wire sensor, a laser rangefinder sensor, or other sensors with distance measurement functions.

[0060] This embodiment acquires the vertical displacement of the second measuring device 205 in real time through a sensor, which can measure the vertical displacement of the second measuring device 205 in real time and efficiently. The measurement results are accurate and reliable. Moreover, the sensor has a wide range of applications, is simple and easy to operate, and is also convenient for operators to maintain and replace.

[0061] In one preferred embodiment, the sensor is a pull-wire sensor.

[0062] In a specific embodiment, when the second measuring device 205 generates a vertical displacement, the pull rope on the pull wire sensor extends, and the sensor in the pull rope sensor outputs an electrical signal proportional to the distance the pull rope moves. The vertical displacement of the second measuring device 205 can be obtained through the electrical signal.

[0063] This embodiment uses a pull-wire sensor to measure the vertical displacement of the second measuring device 205. It has high measurement accuracy, long measurement distance, long service life, convenient installation, and flexible use.

[0064] In a preferred embodiment, S103 obtains the subsidence amount of the third measuring device 206 based on the distance from the first measuring device to the second measuring device, the distance from the first measuring device to the third measuring device, and the vertical displacement, including:

[0065] The length of the first chord of the measuring chord between the first measuring device 204 and the third measuring device 206 is taken as the distance from the first measuring device 204 to the third measuring device 206, and the length of the second chord of the measuring chord between the first measuring device 204 and the second measuring device 205 is taken as the distance from the first measuring device 204 to the second measuring device 205.

[0066] The settlement of the third measuring device 206 is determined based on the vertical displacement, the length of the first chord, the length of the second chord, and the relationship between the settlement and the formula. The formula for the settlement is as follows:

[0067] ;

[0068] Where a' is the subsidence, FA is the length of the first chord, EA is the length of the second chord, and a is the vertical displacement.

[0069] Please refer to Figure 3 , Figure 3 A schematic diagram of a method for measuring track bed settlement provided in an embodiment of the present invention:

[0070] Due to the principle of similar triangles, the ratio of the sinking amount a' of the third measuring device 206 to the vertical displacement amount a of the second measuring device 205 is the same as the length of the first chord FA and the length of the second chord EA.

[0071] In this embodiment, the first measuring device 204, the second measuring device 205, and the third measuring device 206 are connected together by measuring chords. The first chord length FA of the measuring chord between the first measuring device 204 and the third measuring device 206 is used as the distance from the first measuring device 204 to the third measuring device 206, and the second chord length EA of the measuring chord between the first measuring device 204 and the second measuring device 205 is used as the distance from the first measuring device 204 to the second measuring device 205. The distances from the first measuring device 204 to the third measuring device 206 and from the first measuring device 204 to the second measuring device 205 are accurately obtained. At the same time, a formula for the settlement is provided, which can accurately express the relationship between the vertical displacement a, the first chord length FA, the second chord length EA, and the settlement a' of the third measuring device 206.

[0072] This method can accurately and efficiently obtain the subsidence of the third measuring device 206, with precise calculation results and simple implementation.

[0073] In a preferred embodiment, after determining the subsidence amount of the third measuring device 206 based on the distance from the first measuring device to the second measuring device, the distance from the first measuring device to the third measuring device, and the vertical displacement in S103, the method further includes:

[0074] The subsidence amount is sent to the parameter recorder as the track bed subsidence amount after the operation of the stabilization system 201.

[0075] This embodiment records and saves the track bed subsidence after the operation of the stabilization system 201 using a parameter recorder, so that subsequent operators can also obtain the track bed subsidence in real time. This facilitates the subsequent operators' assessment of the changes in the track condition, greatly facilitating the operators' work and enabling timely detection of any abnormalities in the stabilization system 201, thereby improving the reliability of the stabilization system 201.

[0076] In a preferred embodiment, after determining the subsidence amount of the third measuring device 206 based on the distance from the first measuring device to the second measuring device, the distance from the first measuring device to the third measuring device, and the vertical displacement in S103, the method further includes:

[0077] The mileage of the stabilization system 201 during operation is obtained by measuring the wheel located at the bottom of the stabilization system 201.

[0078] Send the mileage to the parameter recorder.

[0079] In a specific embodiment, the measuring wheel is closely attached to the track. The movement of the stabilization system 201 can drive the measuring wheel to rotate. When the measuring wheel rolls on the track, it outputs a corresponding pulse signal. The pulse signal is processed by the signal conversion circuit and sent to the recorder as the mileage of the stabilization system 201.

[0080] This embodiment obtains the mileage of the stabilization system 201 through the measuring wheel, and records and saves the mileage through the parameter recorder, which fully meets the measurement needs of the travel distance of large railway maintenance machinery and facilitates the maintenance and repair work of operators.
