Description

Technical Field

[0001] This invention belongs to the field of monorail train technology and relates to a method and device for adjusting the load of a straddle-type monorail train. Background Technology

[0002] With the rapid development of urban rail transit, straddle-type monorail trains have been widely used due to their low cost, flexible formation, and high passenger comfort. The axle load deviation of monorail vehicles is one of the important factors affecting the vehicle's adhesion and traction capabilities. The greater the axle load deviation, the more obvious the axle load transfer of the vehicle. The greater the load deviation of the guide wheels and stabilizing wheels on both sides of the bogie, the greater the lateral weight imbalance of the vehicle, and the less safe the vehicle operation. At the same time, monorail vehicles all use rubber tires. The greater the axle load deviation and the greater the load deviation of the guide wheels and stabilizing wheels, the more uneven the tire wear and the greater the difficulty of operation and maintenance. In order to ensure the stable operation of the train under various working conditions, it is necessary to ensure the load balance of the train.

[0003] Monorail trains use rubber tires. Existing methods mainly rely on measuring the internal tire pressure of the guide wheels and stabilizer wheels to indirectly infer the load deviation of the guide wheels and stabilizer wheels. However, the accuracy of this load measurement is not good. Therefore, the unbalanced load condition of the vehicle in the pre-delivery preparation state cannot be effectively monitored, and the vehicle load cannot be accurately adjusted.

[0004] Existing methods for adjusting the load of monorail vehicles rely heavily on manual experience to judge load deviations, which lacks systematicity and precision. The overall adjustment time is long, the accuracy is low, and effective traceability is not possible, which affects the safety and stability of the vehicles. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for adjusting the load of a straddle-type monorail train, in order to solve the problem that existing methods for adjusting the load of rail vehicles lack systematicity and accuracy.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] In a first aspect, the present invention provides a load adjustment method for a straddle-type monorail train, comprising:

[0008] Obtain the load values ​​of the running wheels, guide wheels, and stabilizing wheels of the target vehicle, and calculate the load imbalance rate of each running wheel based on the load values ​​of the running wheels;

[0009] The steps of performing a load balance judgment and adjustment method include:

[0010] Based on the unbalance rate of the running wheel load, determine whether there are unbalanced running wheels that do not meet the load balance conditions. If so, add or remove the adjustment pad of the preset thickness at the air spring corresponding to the unbalanced running wheel to make it meet the load balance conditions. If not, perform the load adjustment steps for the guide wheel and the stabilizing wheel.

[0011] Calculate the load imbalance rate of the guide wheel and the stabilizer wheel based on the load values ​​of the guide wheel and the stabilizer wheel;

[0012] Based on the load imbalance rate of the guide wheel and the stabilizing wheel, determine whether there is an unbalanced guide wheel or unbalanced stabilizing wheel that does not meet the load balance condition. If so, adjust the pressure and working height of the air spring corresponding to the unbalanced guide wheel or unbalanced stabilizing wheel to meet the load balance condition. Otherwise, complete the load adjustment of the current wheel.

[0013] Repeat the above steps for load balance judgment and adjustment until all running wheels, guide wheels, and stabilizing wheels meet the load balance conditions.

[0014] The load balance conditions include:

[0015]

[0016] This represents the load imbalance rate of the j-th running wheel on bogie i. This represents the imbalance rate of the j-th guide wheel on bogie i. The imbalance rate of the j-th stabilizing wheel on bogie i. This represents the load on the j-th running wheel of bogie i. This represents the average axle load of all running wheels. This represents the average load on the guide wheel of bogie i. This represents the load on the j-th guide wheel on bogie i; This represents the average load on the guide wheel of bogie i. Let n represent the load on the j-th stabilizing wheel on bogie i, m represent the first balance threshold, n1 represent the second balance threshold, and n2 represent the third balance threshold.

[0017] The method for adjusting the pressure and working height of the air spring corresponding to the unbalanced guide wheel or unbalanced stabilizing wheel is as follows:

[0018] Based on the load values ​​of the unbalanced guide wheel and the unbalanced stabilizing wheel, determine the position and target height of the height valve stem corresponding to the air spring to be adjusted;

[0019] Adjust the height valve stem at the corresponding position to the target height.

[0020] The height control levers at the four corners of the vehicle can operate individually or in combination.

[0021] The method of adding or removing the adjustment pad of preset thickness at the air spring corresponding to the unbalanced running wheel is as follows:

[0022] The first and second traveling wheels to be adjusted are determined. The first traveling wheel to be adjusted is the traveling wheel with the largest imbalance rate of the traveling wheel axle seat. The second traveling wheel to be adjusted is on the same guide frame as the first traveling wheel to be adjusted and both are unbalanced traveling wheels.

[0023] Prioritize adjusting the thickness of the adjusting pad corresponding to the first traveling wheel to be adjusted. If the load balance condition is still not met when the thickness reaches the upper or lower limit, then adjust the thickness of the adjusting pad corresponding to the second traveling wheel to be adjusted until the load of all traveling wheels meets the load balance condition.

[0024] The total thickness of the adjustment pad is ≤10mm, and the thickness increases or decreases by A mm each time it is adjusted, where 0.5mm≤A≤1.5mm.

[0025] It also includes: acquiring the height information of each component of the vehicle relative to the measuring track, adjusting each component to the target height, and repeating the above-mentioned load adjustment method steps until all components are at the target height, and the loads of the running wheels, guide wheels, and stabilizing wheels still meet the load balance condition.

[0026] The steps include obtaining the load values ​​of the target vehicle's running wheels, guide wheels, and stabilizing wheels before proceeding:

[0027] The position information of the target vehicle's running wheels, guide wheels, and stabilizing wheels is obtained, and the positions of the weighing module and force sensing module on the measuring track are adjusted according to the position information.

[0028] The target vehicle is fixed to the target position on the measuring track, and the running wheels are aligned with the weighing module to measure the load value of the running wheels. The guide wheels and stabilizing wheels are aligned with the corresponding force sensing modules to measure the load values ​​of the guide wheels and stabilizing wheels.

[0029] The measuring track includes an adjusting beam and a fixed beam. The adjusting beam is equipped with a slide rail assembly for adjusting the position of the weighing module. Both sides of the adjusting beam and the fixed beam are provided with cavities for accommodating the force sensing module. Different cavity positions correspond to different sizes of the traveling wheel, guide wheel and stabilizing wheel.

[0030] In a second aspect, the present invention provides a load adjustment device for a straddle-type monorail train, comprising:

[0031] The measurement module is used to acquire the load values ​​of the target vehicle's running wheels, guide wheels, and stabilizing wheels;

[0032] The calculation module is used to calculate the load imbalance rate of each running wheel based on the load value of the running wheel, and to calculate the load imbalance rate of the guide wheel and the stabilizing wheel based on the load values ​​of the guide wheel and the stabilizing wheel;

[0041] Example 1

[0042] refer to Figure 2As shown, a straddle-type monorail train load detection device includes: a track, a weighing module 4 installed on the top surface of the track, and a force sensing module 5 installed on the side of the track. The weighing module 4 contacts the running wheels of the monorail train and measures the running wheel load, while the force sensing module 5 contacts the guide wheels and stabilizing wheels and measures the guide wheel load and stabilizing wheel load. The weighing module 4 and the force sensing module 5 are respectively communicatively connected to the control module 12.

[0043] The track includes a fixed beam 2 and an adjusting beam 1 connected end to end. The fixed beam 2 and the adjusting beam 1 are track beams simulating the operation of a monorail train, the main steel structure components, and the main joints for carrying the vehicle and other components. The adjusting beam 1 is equipped with a slide rail and a slider that cooperates with the slide rail. The weighing module 4 is installed on the slider and can move freely on the slide rail with the slider for measuring the load of the running wheels at different distances. The fixed beam 2 is fixedly equipped with a weighing module 4 of the same structure for measuring the load of the running wheels and positioning the vehicle. The fixed beam 2 and the adjusting beam 1 are fixed with a cover plate 9 that completely covers the slide rail. The cover plate 9 and the weighing module 4 form a seamless running plane.

[0044] A web plate 10 is provided on the side of the track. The web plate 10 is configured to limit the running path of the guide wheel and the stabilizing wheel. The web plate 10 is provided with several cavities for accommodating the force sensing module 5. The installation position of the force sensing module 5 is determined according to the position of the guide wheel and the stabilizing wheel.

[0048] Example 2

[0049] refer to Figure 1 As shown, a load adjustment method for a straddle-type monorail train includes:

[0050] The position information of the target vehicle's running wheels, guide wheels, and stabilizing wheels is obtained, and the positions of the weighing module and force sensing module on the track are adjusted according to the position information.

[0051] In this embodiment, the tested rail vehicle includes two sets of bogies (bogie one and bogie two). Each bogie includes a symmetrical set of running wheels, a set of stabilizing wheels, and two sets of guide wheels. The number of weighing modules on the track is 4, and the number of force sensing modules is 12. Based on the pre-measured position information of the vehicle's running wheels, guide wheels, and stabilizing wheels, the position of the slider on the adjustment beam is controlled so that the position of the weighing module on it matches the position of the weighing module on the fixed beam with the position of the vehicle's running wheels. Based on the position information of the guide wheels and stabilizing wheels, force sensing modules are installed in the corresponding cavities on the web. The running wheels of bogie one are numbered A11 and A12, the guide wheels are numbered B11, B12, B13, and B14, and the stabilizing wheels are numbered C11 and C12. The running wheels of bogie two are numbered A21 and A22, the guide wheels are numbered B21, B22, B23, and B24, and the stabilizing wheels are numbered C21 and C22.

[0052] Load measurement is performed using the straddle-type monorail train load detection device described in Example 1. Specifically, after assembling the measuring device described in Example 1, the target vehicle is fixed to the target position on the measuring track, the running wheels are aligned with the weighing module to measure the load value of the running wheels, the guide wheels and stabilizing wheels are aligned with the corresponding force sensing modules to measure the load values ​​of the guide wheels and stabilizing wheels, and the stop block of the wheel stop is controlled to extend.

[0053] Obtain the load values ​​of the running wheels, guide wheels, and stabilizing wheels of the target vehicle, and calculate the load imbalance rate of each running wheel based on the load values ​​of the running wheels;

[0054] In this embodiment, the load value of the weighing module is obtained, and the load imbalance rate of each traveling wheel is calculated. The formula for calculating the axle load imbalance rate of the traveling wheels is as follows: , This represents the axle load of the j-th running wheel on bogie i. This represents the average axle load of all running wheels. The imbalance rate of the axle load of the running wheels.

[0055] The steps of performing a load balance judgment and adjustment method include:

[0056] Based on the unbalance rate of the running wheel load, determine whether there are unbalanced running wheels that do not meet the load balance conditions. If so, add or remove the adjustment pad of the preset thickness at the air spring corresponding to the unbalanced running wheel to make it meet the load balance conditions. Otherwise, perform the load adjustment steps for the guide wheel and the stabilizing wheel.

[0057] If the axle load imbalance rate of the running wheels exceeds the preset first balance threshold... This indicates a large axle load deviation, resulting in decreased vehicle adhesion and traction, which can lead to uneven tire wear. A first and second tracked wheel to be adjusted are identified. The first tracked wheel is the one with the largest axle imbalance rate, and the second tracked wheel is on the same guide frame as the first. Adjustment shims of a preset thickness are added or removed at the air spring position corresponding to the first tracked wheel. When the load on the first tracked wheel is greater than the average load, the shim thickness is reduced; when the load on the first tracked wheel is less than the average load, the shim thickness is increased. If the shim thickness corresponding to the first tracked wheel has reached its upper or lower limit, then an adjustment shim of a preset thickness is added or removed at the air spring position corresponding to the second tracked wheel. The thickness of the shim added each time is A mm, where 0.5 mm ≤ A ≤ 1.5 mm.

[0058] In this embodiment, the thickness of the adjusting shim is linearly positively correlated with the load at its location. For every 1mm increase in the thickness of the adjusting shim, the load at its location and its diagonally opposite location each increase by approximately 180kg, while the load at the remaining locations decreases by approximately 180kg. The total thickness of the adjusting shim is less than 10mm. This adjustment method achieves a balanced distribution of the vehicle's upper load, providing a prerequisite for adjusting the load on the stabilizing wheel and guide wheel. It also ensures that the height adjustment range of the air spring's height valve rod is consistent, and that the range of upward or downward load adjustment is consistent, effectively shortening the adjustment blind spot under extreme operating conditions.

[0059] Calculate the load imbalance rate of the guide wheel and the stabilizer wheel based on the load values ​​of the guide wheel and the stabilizer wheel;

[0060] Based on the load imbalance rate of the guide wheel and the stabilizing wheel, determine whether there is an unbalanced guide wheel or unbalanced stabilizing wheel that does not meet the load balance condition. If so, adjust the pressure and working height of the air spring corresponding to the unbalanced guide wheel or unbalanced stabilizing wheel to meet the load balance condition. Otherwise, complete the load adjustment of the current wheel.

[0061] The formula for calculating the load imbalance rate of the guide wheel is: , This represents the average load on the guide wheel of bogie i. This represents the load on the j-th guide wheel on bogie i.

[0062] The formula for calculating the unbalance rate of the stabilizing wheel load is: , This represents the average load on the guide wheel of bogie i. This represents the load on the j-th stabilizing wheel on bogie i.

[0063] If the load imbalance rate of the guide wheel exceeds the preset second balance threshold, or the load imbalance rate of the stabilizing wheel exceeds the preset third balance threshold, This indicates that the vehicle is severely laterally tilted, making its operation unsafe and posing a risk of rollover. Based on the load and load imbalance rate of the guide wheel and stabilizer wheel, the height valve rod of the corresponding air spring is adjusted to adjust the pressure and working height of the air spring, thereby adjusting the load distribution of the vehicle.

[0064] In one possible implementation, the load imbalance rate of the stabilizer wheel of bogie one is greater than the third balance threshold, wherein the load of C11 is greater than the average value and the load of C12 is less than the average value. The height of the corresponding height valve rod at C11 and / or C12 is adjusted according to the preset valve rod height and load curve, so that the load imbalance rate of C11 and C12 is reduced to below the third balance threshold.

[0065] The loads of C11 and C12 have a coordinated relationship; when the load of C11 increases, the load of C12 decreases, and vice versa. When the load of C11 is less than the average value, based on the operating range of the height valve stem, the height of the height valve stem at C11 can be increased only, or the height of the height valve stem at C12 can be decreased only, or the height of the height valve stem at C11 can be increased while the height of the height valve stem at C12 is decreased. The specific adjustment height of the height valve stem varies and needs to be set according to the actual load value.

[0066] The load imbalance rate of the guide wheel of bogie 2 is greater than the second balance threshold. Among them, the loads of B21 and B22 on the same side of the bogie are greater than the average value, while the loads of B23 and B24 on the other side are less than the average value. The height of the height valve rod at the corresponding position is adjusted according to the preset valve rod height and load relationship curve, so that the load imbalance rate of B21, B22, B23 and B24 is reduced to below the second balance threshold.

[0067] The height of the height valve stem has a non-linear positive correlation with the load at its location. Increasing the height of the height valve stem increases the load at the corresponding location, while decreasing the height of the height valve stem decreases the load at the corresponding location.

[0068] The height control levers at the four corners of the vehicle can operate independently or in concert.

[0069] Obtain the load value of the traveling wheel after the first adjustment. If the load balance condition is met, it indicates that the load adjustment is complete and proceed to the next process. If the load balance condition is not met, repeat the above load adjustment method until the load values ​​of the traveling wheel, guide wheel, and stabilizing wheel all meet the load balance condition.

[0070] Obtain the height information of each component of the vehicle relative to the measuring track, adjust each component to the target height, and repeat the above load adjustment method steps until all components are at the target height, and the loads of the running wheels, guide wheels, and stabilizing wheels still meet the load balance condition.

[0071] Example 3

[0073] The measurement module is used to acquire the load values ​​of the target vehicle's running wheels, guide wheels, and stabilizing wheels;

[0074] The calculation module is used to calculate the load imbalance rate of each running wheel based on the load value of the running wheel, and to calculate the load imbalance rate of the guide wheel and the stabilizing wheel based on the load values ​​of the guide wheel and the stabilizing wheel;

[0075] The determination module is used to determine whether there are unbalanced running wheels that do not meet the load balance conditions based on the load imbalance rate of the running wheels, and to determine whether there are unbalanced guide wheels or unbalanced stabilizing wheels that do not meet the load balance conditions based on the load imbalance rate of the guide wheels and stabilizing wheels.
