Detailed Embodiments

[0019] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0020] As Figure 1 shown, the present application proposes a method for track bed maintenance. In combination with Figure 1 shown, an embodiment of the present application provides a stabilization vehicle: In Figure 1 , the definitions of the following English terms are as follows: Left Rail: Left track; Right Rail: Right track; Rear Bogie Center: Rear bogie center; Front Bogie Center: Front bogie center; The stabilizer car includes multiple inspection cars and a stabilizing downward pressure device for applying a stabilizing downward pressure to the track. Among them, the track includes a left rail 6 and a right rail 7. At least one inspection car is provided with a track superelevation sensor 4, which is used to detect the height difference between the corresponding positions of the left rail 6 and the right rail 7 of the railway track. The multiple inspection cars include a first inspection car 1 at the head of the car body, a second inspection car 2 at the tail of the car body, and a third inspection car 3 arranged between the head and the tail of the car body. The track superelevation sensor 4 is provided on the first inspection car 1, the second inspection car 2, and / or the third inspection car 3. A left-right leveling sensor 5 may also be provided on the third inspection car 3, which is used to detect whether different positions of the left rail 6 of the railway track are level, and whether different positions of the right rail 7 are level. The stabilizer car further includes a processor, which is electrically connected to the above-mentioned electrical components and is used to control the above-mentioned electrical components to perform actions.

[0021] Figures 2 to 4 It is a schematic diagram of the method for ballast bed maintenance provided by the embodiment of the present application. Any of the following methods can be executed in the stabilizer car, or can also be executed in a server or a terminal device that is communicatively connected to the stabilizer car. In the embodiment of the present application, the stabilizer car is used as the execution subject to illustrate the solution.

[0022] Based on the structure of the above-mentioned stabilizer car, as Figure 2 shown, the embodiment of the present application provides a method for ballast bed maintenance, including: S21: The stabilizer car detects the actual superelevation value of the track and obtains the theoretical superelevation value of the track.

[0023] S22: The stabilizer car determines the sinking adjustment amount according to the actual superelevation value and the theoretical superelevation value.

[0024] S23: The stabilizer car adjusts the stabilizing downward pressure of the stabilizing downward pressure device according to the sinking adjustment amount.

[0025] In the embodiment of the present application, the track superelevation value refers to the height difference between the corresponding positions of the left rail and the right rail. The actual superelevation value refers to the height difference between the corresponding positions of the currently detected left rail and right rail. The theoretical superelevation value refers to the height difference between the corresponding positions of the left rail and the right rail calculated according to the theoretical track file. The stabilizer car adjusts the stabilizing downward pressure of the stabilizing downward pressure device according to the sinking adjustment amount, so that the height difference between the corresponding positions of the left rail and the right rail is within the error range of the theoretical superelevation value.

[0026] By using the method for track bed maintenance provided in the embodiments of the present application, the actual superelevation value of the line is detected, the theoretical superelevation value of the line is obtained, and based on the actual superelevation value and the theoretical superelevation value, the subsidence adjustment amount of the line is determined. Finally, according to the subsidence adjustment amount, the stable downward pressure of the stable downward pressure device is adjusted. By determining the subsidence adjustment amount of the line based on the real-time obtained actual superelevation value and theoretical superelevation value of the line and timely adjusting the downward pressure of the stable downward pressure device to perform stable operation on the railway line, real-time feedback adjustment of the geometric parameters of the railway line is achieved, the influence of different superelevation degrees of railway lines at different positions on railway line maintenance is reduced, the quality of stable operation on the railway line is improved, and thus the stability and safety of the railway line are enhanced.

[0027] Based on the structure of the stabilizer car described above, as Figure 3 shown, the embodiments of the present application provide a method for track bed maintenance, including: S31: The stabilizer car obtains the detection values of at least one line superelevation sensor.

[0028] S32: When only the detection value of one line superelevation sensor is obtained, the stabilizer car directly uses the obtained detection value as the actual superelevation value of the line.

[0029] S33: When the detection values of multiple line superelevation sensors are obtained, the stabilizer car converts the multiple detection values into the actual superelevation value of the line through a mathematical method.

[0030] S34: The stabilizer car obtains the theoretical superelevation value of the line.

[0031] S22: The stabilizer car determines the subsidence adjustment amount of the line according to the actual superelevation value and the theoretical superelevation value.

[0032] S23: The stabilizer car adjusts the stable downward pressure of the stable downward pressure device according to the subsidence adjustment amount.

[0033] Using the method for track bed maintenance provided by the embodiments of the present application, the detection value is obtained through at least one track elevation sensor. When only the detection value of one track elevation sensor is obtained, the stabilization vehicle directly uses the obtained detection value as the actual track elevation value of the line. When only one track elevation sensor provides data, the processing flow can be simplified. Especially in the case where the track elevation sensors are sparsely distributed or in specific detection scenarios, this single detection value is directly regarded as the actual track elevation value of the line, so that the stabilization vehicle can quickly respond and make adjustments. When the detection values of multiple track elevation sensors are obtained, the stabilization vehicle converts the multiple detection values into the actual track elevation value of the line through a mathematical method. Further, when the stabilization vehicle is equipped with multiple track elevation sensors, the average value or weighted average value of the multiple detection values can be calculated by a mathematical method to obtain a more comprehensive and reliable actual track elevation value of the line, thereby reducing the influence of possible errors or outliers of a single track elevation sensor on the overall evaluation of the railway line and improving the accuracy and stability of the track elevation detection result.

[0034] Optionally, the stabilization vehicle converts the multiple detection values into the actual track elevation value of the line through a mathematical method, including: the stabilization vehicle determines the average value of the multiple detection values as the actual track elevation value of the line; or, the stabilization vehicle determines the weighted average value of the multiple detection values as the actual track elevation value of the line.

[0035] Based on this, the stabilization vehicle determines the average value of the multiple detection values as the actual track elevation value of the line. When the average value is used as the actual track elevation value of the line, the detection value of each track elevation sensor is given the same weight. In the case where the track elevation sensors are evenly distributed and the contribution of each track elevation sensor to the detection result of the final actual track elevation value is equal, the method of using the average value is simpler and more direct. The stabilization vehicle determines the weighted average value of the multiple detection values as the actual track elevation value of the line. When the weighted average value is used as the actual track elevation value of the line, the stabilization vehicle will assign different weights to the detection values of the track elevation sensors at different positions according to the position of each track elevation sensor, the accuracy of historical data, or other relevant factors. For example, if the track elevation sensor is located at a key position on the curve section, or the historical data of this track elevation sensor shows higher accuracy, then a greater weight can be assigned to the detection value of this track elevation sensor. Considering the contribution of different track elevation sensors to the accuracy of the detection result of the actual track elevation value of the line, it can more accurately reflect the actual track elevation value of the line in the case where the track elevation sensors are unevenly distributed on the stabilization vehicle or the line conditions are complex and changeable.

[0036] Based on the above structure of the stabilization vehicle, as Figure 4 shown, the embodiments of the present application provide a method for track bed maintenance, including: S41: The stabilizer vehicle obtains the first detection value of the track superelevation sensor on the first inspection vehicle and / or the second detection value of the track superelevation sensor on the second inspection vehicle and / or the third detection value of the track superelevation sensor on the third inspection vehicle.

[0037] S32: When only the detection value of one track superelevation sensor is obtained, the stabilizer vehicle directly uses the obtained detection value as the actual superelevation value of the track.

[0038] S33: When the detection values of multiple track superelevation sensors are obtained, the stabilizer vehicle converts the multiple detection values into the actual superelevation value of the track through a mathematical method.

[0039] S34: The stabilizer vehicle obtains the theoretical superelevation value of the track.

[0040] S22: The stabilizer vehicle determines the sinking adjustment amount of the track based on the actual superelevation value and the theoretical superelevation value.

[0041] S23: The stabilizer vehicle adjusts the stable downward pressure of the stable downward pressure device according to the sinking adjustment amount.

[0042] In the embodiment of the present application, left and right leveling sensors may also be provided on the third inspection vehicle to detect whether there is a vertical height difference in the track direction at different positions of the left rail and whether there is a vertical height difference in the track direction at different positions of the right rail. Thus, according to the detection results, the operating personnel can be reminded in time, and the downward pressure of the stable downward pressure device can be corrected to make the vertical height difference in the track direction of the left rail and the right rail less than the second threshold.

[0043] By using the method for track bed maintenance provided in the embodiment of the present application, the first inspection vehicle is located at the front end of the stabilizer vehicle and is responsible for detecting the track superelevation value of the front track. The second inspection vehicle is located at the rear end of the stabilizer vehicle and is responsible for detecting the track superelevation value of the rear track. The third inspection vehicle is located in the middle of the stabilizer vehicle and is responsible for detecting the track superelevation value of the middle track. The layout of the three inspection vehicles in the front and rear ensures that the stabilizer vehicle can continuously and comprehensively monitor the superelevation state of the entire track during the traveling process. Therefore, the stabilizer vehicle obtains the first detection value of the track superelevation sensor on the first inspection vehicle and / or the second detection value of the track superelevation sensor on the second inspection vehicle and / or the third detection value of the track superelevation sensor on the third inspection vehicle, and can more accurately understand the situation of the track superelevation value of the entire track. Compared with single-point detection, the above method can provide richer track superelevation data, so that the stabilizer vehicle can perform more targeted maintenance operations.

[0044] Optionally, the stabilizer converts multiple detected values into the actual superelevation value of the line through mathematical methods, including: the stabilizer determines the first weighting coefficient of the first detected value, the second weighting coefficient of the second detected value, and the third weighting coefficient of the third detected value according to the interval distances between the first inspection vehicle, the second inspection vehicle, and the third inspection vehicle; the stabilizer calculates the weighted average value of the first detected value, the second detected value, and the third detected value according to the first weighting coefficient, the second weighting coefficient, and the third weighting coefficient; the stabilizer determines that the weighted average value is the actual superelevation value of the line.

[0045] Based on this, by using inspection vehicles distributed at different positions to obtain the detected values of the line superelevation, considering the interval distances between different inspection vehicles, and determining the contribution degrees of different detected values to the overall superelevation state of the track according to the importance of the line superelevation sensors at different positions and the influence degree on the track superelevation state, weighting coefficients reflecting their contribution degrees are assigned to each detected value, and through the weighted average method, the detected values are converted into the actual superelevation value of the line, so as to more accurately reflect the true state of the track superelevation and provide a basis for the subsequent maintenance operation decision-making of the railway line.

[0046] Optionally, the stabilizer determines the sinking adjustment amount of the line according to the actual superelevation value and the theoretical superelevation value, including: the stabilizer inputs the actual superelevation value and the theoretical superelevation value into the operation amount calculation model to obtain the sinking adjustment amount of the line.

[0047] In the application embodiment, the stabilizer vehicle can determine the settlement adjustment amount of the track according to the actual superelevation value, the theoretical superelevation value, and / or the detection values of the left and right leveling sensors. That is, the stabilizer vehicle can determine the settlement adjustment amount of the track according to the actual superelevation value and the theoretical superelevation value; it can also determine the settlement adjustment amount of the track according to the actual superelevation value, the theoretical superelevation value, and the detection values of the left and right leveling sensors; it can also determine the settlement adjustment amount of the track according to the detection values of the left and right leveling sensors, etc. Correspondingly, the workload calculation model can include multiple input parameters. For example, the theoretical superelevation value, the detection value of the track superelevation sensor, and / or the detection values of the left and right leveling sensors, etc. By inputting the above parameters, the workload calculation model can comprehensively consider the vertical height difference between the left track and the right track of the track, as well as the vertical height differences of the left track and the right track along the track direction respectively, to obtain the settlement adjustment amount corresponding to the current track state and the theoretical track state. In practical applications, the algorithm of the workload calculation model can be a difference algorithm or other algorithms. For example, the stabilizer vehicle can directly calculate the difference between the theoretical superelevation value and the actual superelevation value to obtain the settlement adjustment amount; or, the stabilizer vehicle can calculate the difference between the theoretical superelevation value and the actual superelevation value to obtain an initial value, and then correct the initial value through the detection values of the left and right leveling sensors to obtain the settlement adjustment amount; or, the stabilizer vehicle can determine an adjustment coefficient according to the detection values of the left and right leveling sensors, and then calculate the product of the adjustment coefficient and the difference between the theoretical superelevation value and the actual superelevation value to obtain the settlement adjustment amount, etc.

[0048] In this way, the actual superelevation value is obtained by real-time detection of the track superelevation sensor on the stabilizer vehicle, which reflects the actual geometric state of the current track, while the theoretical superelevation value is preset according to the design standards and safety requirements of the railway track, representing the geometric parameters of the track in the ideal state. By inputting the above actual superelevation value and theoretical superelevation value into the workload model, the settlement adjustment amount corresponding to the difference between the actual state and the theoretical state can be obtained, thereby improving the accuracy of the settlement adjustment amount.

[0049] Based on the above structure of the stabilizer vehicle, as Figure 5 shown, when the algorithm of the workload calculation model is a difference algorithm, the application embodiment provides a method for track bed maintenance, including: S21: The stabilizer vehicle detects the actual superelevation value of the track and obtains the theoretical superelevation value of the track.

[0050] S51: The stabilizer vehicle calculates the difference between the theoretical superelevation value and the actual superelevation value.

[0051] S52: The stabilizer vehicle determines that the difference is the settlement adjustment amount of the track.

[0052] S23: The stabilizer vehicle adjusts the stable downward pressure of the stable downward pressure device according to the settlement adjustment amount.

[0053] Using the method for track bed maintenance provided by the embodiments of the present application, the difference between the theoretical superelevation value and the actual superelevation value is calculated by the stabilizer car, and the difference is determined as the settlement adjustment amount of the line. The actual superelevation value is obtained by real-time detection of the track superelevation sensor on the stabilizer car, which reflects the actual geometric state of the current track, while the theoretical superelevation value is preset according to the design standards and safety requirements of the railway line, representing the track geometric parameters in the ideal state. Therefore, by calculating the difference between the theoretical superelevation value and the actual superelevation value, the stabilizer car can quantify the superelevation deviation of the track, and the difference is the settlement adjustment amount of the line. By comparing the actual superelevation value and the theoretical superelevation value to determine the settlement adjustment amount of the line, the maintenance operation can more precisely adapt to the actual state of the railway line. In practical applications, if the actual superelevation value is lower than the theoretical superelevation value, it indicates that the track may have settled, and it is necessary to increase the downward pressure to lift the track. On the contrary, if the actual superelevation value is higher than the theoretical superelevation value, it may be necessary to reduce the downward pressure to lower the track. The above closed-loop adjustment mechanism not only improves the operation efficiency, reduces unnecessary resource waste, but also enhances the stability and safety of the railway line. By precisely controlling the superelevation of the track, the vibration and impact during train passing can be reduced, the service life of the track and the vehicle can be extended, and at the same time, the comfort of passengers can also be improved.

[0054] Optionally, the stabilizer car adjusts the stable downward pressure of the stable downward pressure device according to the settlement adjustment amount, including: the stabilizer car determines the target pressure corresponding to the settlement adjustment amount according to the preset corresponding relationship; the stabilizer car determines the target pressure as the stable downward pressure.

[0055] Based on this, the settlement adjustment amount is calculated based on the difference between the actual superelevation value and the theoretical superelevation value. Therefore, the settlement adjustment amount directly reflects the deviation between the current state of the track and the ideal state. By matching the settlement adjustment amount with the preset corresponding relationship, the stabilizer car can determine the target pressure to be achieved, that is, the downward pressure that the stable downward pressure device should apply, to correct the superelevation deviation of the track. Using the settlement adjustment amount to dynamically adjust the downward pressure of the stable downward pressure device makes the railway line maintenance operation more precise and efficient. In practical applications, if the settlement adjustment amount indicates that the track is too low, the stabilizer car will increase the downward pressure to lift the track, and vice versa, to ensure that the geometric shape of the track meets the design requirements. Therefore, by precisely controlling the downward pressure of the stable downward pressure device, the stabilizer car can reduce over-compaction or under-compaction of the track, avoid premature aging of the track or increase in maintenance costs caused thereby, which helps to extend the service life of the track, reduce future maintenance requirements and costs, and at the same time can also improve the smoothness of train operation and the comfort of passengers.
