Description

Technical Field

[0001] This invention relates to the field of locomotive technology, and in particular to a system and method for measuring and adjusting vertical stop spacing. Background Technology

[0002] As a key component that limits the vertical displacement of the car body and bogie, the spacing of the locomotive vertical stops directly affects the stability, comfort, and structural safety of the locomotive, and is a core inspection item in locomotive maintenance.

[0003] Currently, the measurement of vertical stop gap mainly relies on traditional manual operation: maintenance personnel need to insert the caliper into the stop gap and clamp it, then take it out and use a steel ruler to measure the caliper opening distance, manually record the data, and calculate the shim adjustment amount in combination with the locomotive weighing report. This method has the following drawbacks: First, the measurement process is slow. Manual operation of the calipers can easily lead to clamping deviations due to uneven force application, and the steel ruler readings are subject to visual errors. The overall accuracy is only ±1mm, which is insufficient to meet the requirements of modern locomotives for accuracy within ±0.5mm. Second, it is highly dependent on manual operation. During measurement, the insertion angle of the device relies entirely on manual experience. If the measuring tool tilts due to narrow gaps or obstructed vision, it will further introduce cosine errors, causing deviations between the measured value and the actual vertical distance, which cannot be corrected manually. Third, it has poor efficiency and traceability. Each locomotive needs to measure four vertical stops, and the entire process relies on manual data recording. This is not only time-consuming (15-20 minutes per locomotive) but also prone to errors and omissions. Furthermore, handwritten records are difficult to link with weighing data for analysis, hindering subsequent quality traceability. Summary of the Invention

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0046] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] Figure 1 This is a schematic diagram of the structure of the first type of vertical stop spacing measurement and adjustment system provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of a caliper provided in an embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the vertical stop distance measurement and adjustment system includes: a ranging module 10 and a control module 20; the ranging module 10 includes a drive motor 101 and a caliper 102; the caliper 102 includes a movable clamp 1021 and a fixed clamp 1022; the movable clamp 1021 is connected to the fixed clamp 1022 via a rotating shaft 1023; the output shaft of the drive motor 101 is connected to the rotating shaft 1023, and is used to drive the rotating shaft 1023 to move the movable clamp 1021 relative to the fixed clamp 1022; the control module 20 is electrically connected to the drive motor 101, and is used to obtain the total rotation angle of the drive motor 101, and determine the current vertical stop distance based on the total rotation angle and the arm length of the caliper 102, and is also used to determine the target shim thickness based on the current vertical stop distance and the preset vertical stop distance.

[0048] Specifically, the current vertical stop spacing needs to meet the preset vertical stop spacing; otherwise, the lateral movement of the frame stop and axle box stop will not meet the requirements when the locomotive is running on a curve, resulting in the danger of stop contact friction. The vertical stops 100 can be located on the measuring frame 200.

[0049] Specifically, the drive motor 101 includes an output shaft. The drive motor 101 can convert electrical energy into mechanical energy, and then transmit the mechanical energy through the output shaft.

[0050] Specifically, the caliper 102 includes a movable locking foot 1021 and a fixed locking foot 1022; the movable locking foot 1021 is connected to the fixed locking foot 1022 via a rotating shaft 1023, meaning the fixed locking foot 1022 is fixed and cannot be moved. During the measurement of the vertical stop spacing, the fixed locking foot 1022 can first be brought into contact with the inner wall of one of the vertical stops, such as... Figure 1 The left vertical stop is located in the middle. The movable locking foot 1021 is connected to the fixed locking foot 1022 via a rotating shaft 1023, and the output shaft of the drive motor 101 is connected to the rotating shaft 1023. Thus, the rotation of the output shaft can drive the rotating shaft 1023 to move the movable locking foot relative to the fixed locking foot 1022 until the movable locking foot 1021 contacts the inner wall of the other vertical stop. Figure 2 The right vertical stop is engaged, at which point the drive motor 101 stops and the movable locking foot 1021 stops moving.

[0051] Specifically, the total rotation angle of the drive motor 101 can be understood as the rotation angle of the drive motor from the start of operation to the point where the movable locking foot 1021 contacts the inner wall of another vertical stop and stops. Furthermore, the number of pulses of the drive motor 101 during this process can be obtained, and then the fixed angle corresponding to each step of the drive motor 101 can be calculated from the number of pulses. For example, 1.8° / step means that each step of the drive motor 101 corresponds to 1.8°. Thus, the total rotation angle θ1 can be accurately obtained by accumulating the number of pulses.

[0052] Specifically, the caliper arm length L can be understood as the length of the movable locking pin 1021.

[0053] Furthermore, the control module 102 determines the current vertical stop distance based on the total rotation angle θ1 and the caliper arm length L, that is, it calculates the current vertical stop distance d1 using the trigonometric function formula, d1 = 2 × L × sin(θ1 / 2), thereby enabling automatic measurement of the current vertical stop distance. Compared with the manual measurement method in the prior art, this embodiment of the invention does not require manual opening of the caliper, nor does it require manual reading to obtain the current vertical stop distance. Therefore, the current vertical stop distance measurement method is simple and can eliminate the interference of human factors on the measurement results, thus ensuring measurement accuracy.

[0054] Specifically, the preset vertical stop spacing can be understood as the ideal vertical stop spacing of the current locomotive pre-stored by the control module. The preset vertical stop spacing is related to the current locomotive type and standard axle load. Axle load can be understood as the vertical static load acting on the rails by each wheelset when the locomotive is stationary. Since the axle load is different for each type of locomotive, the corresponding preset vertical stop spacing is also different.

[0055] Furthermore, the control module 20 determines the current vertical stop distance based on the total rotation angle and the arm length of the caliper 102. It is also used to determine the target shim thickness based on the current vertical stop distance and the preset vertical stop distance. This allows for the addition or reduction of shims based on the target shim thickness value, ensuring that the current vertical stop distance meets the preset vertical stop distance, thereby guaranteeing the stability and reliability of locomotive operation.

[0056] It should be noted that the target shim thickness is equal to the difference between the preset vertical stop distance and the current vertical stop distance. If the difference between the preset vertical stop distance and the current vertical stop distance is positive, a shim needs to be added at the vertical stop position; if the difference between the preset vertical stop distance and the current vertical stop distance is negative, a shim needs to be reduced at the vertical stop position.

[0057] The vertical stop spacing measurement and adjustment system provided in this invention connects the output shaft of a drive motor to a rotating shaft, and the movable clamp of the drive motor is connected to a fixed clamp via the rotating shaft. When the drive motor starts, the output shaft rotates, driving the rotating shaft to move the movable clamp relative to the fixed clamp until both the fixed and movable clamps contact the vertical stops, at which point the motor stops rotating. A control module electrically connected to the drive motor acquires the total rotation angle of the drive motor and determines the current vertical stop spacing based on the total rotation angle and the caliper arm length, thus enabling the measurement of the vertical stop spacing. The control module also determines the target shim thickness based on the current vertical stop spacing and a preset vertical stop spacing, thereby enabling adjustment of the vertical stop spacing based on the target shim thickness, ensuring the stability and reliability of the locomotive operation.

[0058] Optional, Figure 3 This is a schematic diagram of the structure of the second type of vertical stop spacing measurement and adjustment system provided in the embodiment of the present invention. (Continue referring to...) Figure 2 and Figure 3 The vertical stop distance measurement and adjustment system also includes: an attitude detection module 30; the attitude detection module 30 is mounted on the caliper 102 and is used to detect the angle between the opening of the caliper 20 and the first direction, and output an angle signal; the first direction (e.g. Figure 2 The X direction shown is the same as the arrangement direction of the two vertical stops 100 in the same bogie; the control module 20 is also electrically connected to the attitude detection module 30 to acquire angle signals and determine the corrected vertical stop spacing based on the angle signals and the current vertical stop spacing.

[0059] Specifically, the attitude detection module 30 is mounted on the caliper 102. When the caliper 102 extends into the vertical stop gap, if the caliper tilts (not perpendicular to the vertical stop plane) due to an operating angle deviation, the attitude detection module 30 can detect the tilt angle of the caliper 102, which is the angle θ2 between the opening of the caliper 20 and the first direction. The control module 20 is electrically connected to the attitude detection module 30. Thus, the control module 20 can correct the current vertical stop gap based on the tilt angle θ2 output by the attitude detection module 30, preventing cosine errors caused by caliper tilt, thereby further improving the measurement accuracy of the vertical stop gap measurement and adjustment system.

[0060] Furthermore, Figure 4 This is an equivalent schematic diagram of the measurement result corresponding to caliper tilt provided in an embodiment of the present invention, such as... Figure 4 As shown, the corrected vertical stop spacing d2 satisfies: d2=d1×cos(θ2).

[0061] Optional, continue to refer to Figure 3 The attitude detection module 30 includes a gyroscope.

[0062] Specifically, a gyroscope is an angular velocity sensor, which can directly detect the rotational angular velocity and then obtain the angle between the caliper opening and the first direction based on the rotational angular velocity.

[0063] Specifically, a gyroscope is used as the attitude detection module 30, which has a fast response speed and high measurement accuracy, thereby improving the stability and reliability of the vertical stop distance measurement and adjustment system.

[0064] Optional, continue to refer to Figure 2 and Figure 3 The vertical stop spacing measurement and adjustment system also includes a pressure detection module 40; the pressure detection module 40 is located on the side of the movable foot 1022 away from the fixed foot 1021, and is used to detect the pressure when the movable foot 1022 contacts the inner wall of the vertical stop, and output a pressure signal; the control module 20 is also electrically connected to the pressure detection module 40, and is used to acquire the pressure signal and control the output shaft to stop rotating according to the pressure signal.

[0065] Specifically, the pressure detection module 40 is located on the side of the movable foot 1022 away from the fixed foot 1021. For example, the pressure detection module 40 can be located at the end of the movable foot 1022. In this way, when the movable foot 1022 contacts the inner wall of the vertical stop, the pressure detection module 40 can detect the pressure signal and transmit the pressure signal to the control module 20.

[0066] Specifically, the control module 20 acquires the pressure signal and controls the output shaft to stop rotating according to the pressure signal. As a result, the rotating shaft 1023 can stop driving the movable foot 1022 to continue moving. This allows the drive motor to stop immediately when the movable foot 1022 contacts the inner wall of the vertical stop, which helps to ensure the accuracy of the total rotation angle and thus improves the measurement accuracy of the vertical stop distance.

[0067] Optionally, the pressure detection module 40 includes a pressure sensor to detect pressure when the movable foot 1022 contacts the inner wall of the vertical stop.

[0068] Optional, continue to refer to Figure 3 The vertical stop spacing measurement and adjustment system also includes: a display module 50; the display module 50 is communicatively connected to the control module 20 and is used to display the current vertical stop spacing, the preset vertical stop spacing, and the target shim thickness.

[0069] Specifically, the display module 50 and the control module 20 can communicate via a serial communication interface. The display module 50 can display the current vertical stop distance, the preset vertical stop distance, the angle between the caliper opening and the first direction, and the thickness of the target pad, etc., so that the user can view them in a timely manner, which helps to improve the interactive effect.

[0070] For example, the display module may employ a high-contrast organic light-emitting diode display.

[0071] Understandably, the display module can also display the current time and the position of the vertical stop, which can be left front, left rear, right front, or right rear. The control module 20 can also pre-store the thickness information of various shims, such as shims with thicknesses of 0.3mm, 1.5mm, and 0.2mm. For example, when the display module 50 displays "Left Front: +1.7mm" and the recommended shim specification is "Recommended to use a 1.5mm + 0.2mm combination shim," it means that a 1.7mm thick shim needs to be added to the vertical stop at the left front position; that is, a combination shim with a thickness of 1.5mm and a thickness of 0.2mm can be used.

[0072] It should be noted that users can adjust the current vertical stop spacing according to the target shim thickness displayed on the display module 50, so that the current vertical stop spacing is equal to the preset vertical stop spacing.

[0073] For example, if the display module 50 displays "Left Front: +1.7mm", it means that a 1.7mm thick shim needs to be added to the vertical stop at the left front position. If the display module 50 displays "Right Rear: -0.3mm", it means that a 0.3mm thick shim needs to be removed from the vertical stop at the right rear position. "+" indicates that a shim needs to be added, and "-" indicates that a shim needs to be removed. For example, if the caliper is tilted during measurement, the display module 50 can display "Tilting Angle: 2.5°", which is θ2 = 2.5°.

[0074] Optionally, the vertical stop spacing measurement and adjustment system may also include a storage module, which is electrically connected to the control module and is used to store information such as the current time, the position signal of the vertical stop, the current vertical stop spacing, the preset vertical stop spacing, and the target shim thickness, so that it can be viewed or retrieved later.

[0075] Optional, Figure 5 This is a flowchart illustrating the first method for measuring and adjusting the vertical stop spacing provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the method for measuring and adjusting the vertical stop spacing includes:

[0076] S101. Obtain the total rotation angle of the drive motor and the preset vertical stop distance.

[0077] Specifically, the total rotation angle can be understood as the rotation angle of the drive motor from startup to stopping when the movable locking foot contacts the inner wall of another vertical stop. The preset vertical stop spacing is related to the standard axle load of the current locomotive. Axle load can be understood as the vertical static load acting on the rails by each wheelset when the locomotive is stationary. Since the axle load is different for each type of locomotive, the corresponding preset vertical stop spacing is also different.

[0078] S102. Determine the current vertical stop distance based on the total rotation angle and the caliper arm length.

[0079] For details, please refer to [link / reference]. Figure 2 The control module determines the current vertical stop distance based on the total rotation angle θ1 and the caliper arm length L, specifically by calculating the current vertical stop distance d1 using trigonometric formulas: d1 = 2 × L × sin(θ1 / 2). This enables automatic measurement of the current vertical stop distance. Compared to existing methods that rely on manual measurement, this invention eliminates the need for manual caliper opening and manual reading of the current vertical stop distance. This simplified measurement method eliminates human interference, ensuring measurement accuracy.

[0080] S103. Determine the target gasket thickness based on the current vertical stop spacing and the preset vertical stop spacing.

[0081] Specifically, the control module determines the current vertical stop distance based on the total rotation angle and the caliper arm length. It also determines the target shim thickness based on the current vertical stop distance and the preset vertical stop distance. This allows the current vertical stop distance to meet the preset vertical stop distance by adding or removing shims, thereby ensuring the stability and reliability of locomotive operation.

[0082] It should be noted that the target shim thickness is equal to the difference between the preset vertical stop distance and the current vertical stop distance. If the difference between the preset vertical stop distance and the current vertical stop distance is positive, a shim needs to be added at the vertical stop position; if the difference between the preset vertical stop distance and the current vertical stop distance is negative, a shim needs to be reduced at the vertical stop position.

[0083] The vertical stop spacing measurement and adjustment method provided in this invention determines the current vertical stop spacing based on the total rotation angle and the caliper arm length, thus enabling automatic measurement of the vertical stop spacing with high accuracy. Furthermore, the target shim thickness is determined based on the current vertical stop spacing and a preset vertical stop spacing, allowing for adjustment of the current vertical stop spacing. By increasing or decreasing the shim thickness, the current vertical stop spacing is made to meet the preset vertical stop spacing, thereby ensuring the safety performance of the locomotive during operation.

[0084] Optional, Figure 6 This is a flowchart illustrating the second method for measuring and adjusting the vertical stop spacing provided in an embodiment of the present invention. Figure 6 Based on the above embodiments, the method for measuring and adjusting the vertical stop spacing is further elaborated, such as... Figure 6 As shown, the method for measuring and adjusting the vertical stop spacing includes: S201, Obtain pressure signal.

[0085] S201, Obtain pressure signal.

[0086] Specifically, the pressure signal is obtained through the pressure detection module.

[0087] S202. Control the output shaft to stop rotating according to the pressure signal.

[0088] Specifically, when the movable foot contacts the inner wall of the vertical stop, the pressure detection module detects the pressure signal and transmits it to the control module. The control module then controls the output shaft to stop rotating based on the pressure signal. This stops the rotating shaft from driving the movable foot to continue moving, allowing the drive motor to stop immediately upon contact with the inner wall of the vertical stop. This helps ensure the accuracy of the obtained total rotation angle, thereby improving the measurement accuracy of the vertical stop distance.

[0089] S203. Obtain the total rotation angle of the drive motor and the preset vertical stop distance.

[0090] Optionally, the number of pulses of the drive motor is obtained; the total rotation angle is determined based on the number of pulses. That is, by obtaining the number of pulses of the drive motor, the fixed angle corresponding to each step of the drive motor can be calculated. For example, 1.8° / step, that is, each step of drive motor 101 corresponds to 1.8°. In this way, the total rotation angle θ1 can be accurately obtained by accumulating the number of pulses.

[0091] S204. Determine the current vertical stop distance based on the total rotation angle and the caliper arm length.

[0092] S205, Obtain the angle signal.

[0093] Specifically, the angle signal is obtained through the attitude detection module. The attitude detection module can detect the tilt angle of the caliper, that is, the angle θ2 between the caliper opening and the first direction.

[0094] S206. Determine the corrected vertical stop distance based on the angle signal and the current vertical stop distance.

[0095] Specifically, the control module can correct the current vertical stop distance based on the tilt angle θ2 output by the attitude detection module, thereby further improving the measurement accuracy of the vertical stop distance measurement and adjustment system.

[0096] Furthermore, the vertical stop spacing d2 is modified to satisfy: d2 = d1 × cos(θ2).

[0097] S207. Determine the target gasket thickness based on the difference between the preset vertical stop spacing and the corrected vertical stop spacing.

[0098] Specifically, the target shim thickness is equal to the difference between the preset vertical stop distance and the corrected vertical stop distance. That is, target shim thickness = preset vertical stop distance - corrected vertical stop distance. This allows the target shim thickness to be determined, thereby enabling the adjustment of the vertical stop distance.

[0099] The vertical stop spacing measurement and adjustment method provided in this invention controls the output shaft to stop rotating based on a pressure signal. This allows the drive motor to stop immediately when the movable clamp contacts the inner wall of the vertical stop, which helps ensure the accuracy of the total rotation angle and thus improves the measurement accuracy of the vertical stop spacing. Furthermore, the target shim thickness is determined based on the difference between the preset vertical stop spacing and the corrected vertical stop spacing. This allows for correction of the current vertical stop spacing and prevents measurement errors caused by caliper tilt.

[0100] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
