[0002] Train wheels are important components of the train running system. Train wheels are in direct contact with the rails and are closely related to the safe operation of the train. Therefore, after a long period of use, it is necessary to test the wear of the train wheel tread to determine whether the train wheel can continue to be used.

[0003] Meanwhile, application number CN219319249U, entitled "A Train Wheel Wear Measurement Frame," describes a train wheel wear measurement frame comprising a base plate, a train wheel body mounted on top of the base plate, and a measuring mechanism mounted on top of the base plate. This addresses the problem that most existing methods for measuring train wheel tread wear rely on using a tread wear meter to measure the wear on the bottom of the train wheel tread. Since the tread wear meter is handheld, instability can lead to inaccurate measurement data, affecting the assessment of the train wheel tread wear. Furthermore, measuring the train wheel tread requires workers to squat down to measure multiple points on the tread, which can cause fatigue and reduce the efficiency of the measurement, ultimately impacting the effectiveness of the method.

[0004] The above-mentioned technical solution requires a circular measurement of the wheel during use to ensure accurate measurement of each part. This requires operators to continuously rotate the rotating column, resulting in poor measurement efficiency and a significant waste of time and manpower. The train wheel measurement process is quite inconvenient.

[0005] Therefore, a train wheel wear measurement device is proposed to address the above problems. Summary of the Invention

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6 As shown, this utility model provides a train wheel wear measurement device, including a measuring platform 1 and a laser rangefinder 12 installed inside the measuring platform 1.

[0028] The surface of the measuring table 1 is equipped with a wheel-wrap measuring assembly 2. The wheel-wrap measuring assembly 2 includes a circular disk 21 rotatably connected to a circular groove inside the measuring table 1, multiple racks 22 mounted on the surface of the circular disk 21, a drive disk 23 for intermittent wheel wrapping, a drive rod 24, a rack 29, a connecting rod 25, a cross plate 26, and a push rod 28.

[0029] The drive rod 24 is rotatably connected inside the measuring platform 1. The drive disk 23 is set in a circular groove inside the measuring platform 1. One end of the drive rod 24 is connected to the drive disk 23. The rack 29 is connected to the drive disk 23 and meshes with the rack 22. The cross plate 26 is installed on the surface of the circular disk 21. The connecting rod 25 is installed on the surface of the cross plate 26. The push rod 28 is slidably connected inside the connecting rod 25. One end of the push rod 28 passes through the connecting rod 25 and is connected to the laser rangefinder 12. This allows for convenient circumferential measurement of the wheel, avoiding the need for operators to manually rotate the wheel continuously, reducing manual operation, improving the measurement effect of the train wheel, and enabling omnidirectional circumferential measurement of the train wheel, thus reducing measurement errors.

[0030] A servo motor 27 is installed in a groove inside the measuring platform 1. The output end of the servo motor 27 passes through the groove in the measuring platform 1 and is connected to one end of the drive rod 24, which makes it convenient for the operator to drive the device and further improves the device's performance.

[0031] Multiple racks 22 are arranged in a circle around the center point of the circular disk 21, which enables the circular disk 21 to be rotated intermittently.

[0032] The measuring stage 1 is equipped with a push measuring component 3. The push measuring component 3 includes a support block 32 symmetrically mounted on the surface of the push rod 28, a limiting plate 33 slidably connected inside the connecting rod 25, and a return spring 34 for automatic push.

[0033] The support block 32 is inserted into the positioning groove opened on the surface of the connecting rod 25. The other end of the push rod 28 is connected to the limiting plate 33. A return spring 34 is sleeved on the surface of the push rod 28. One end of the return spring 34 is connected to the limiting plate 33, and the other end of the return spring 34 is installed inside the connecting rod 25. This allows the laser rangefinder 12 to be easily pushed out of the measuring table 1, making it convenient for the operator to perform circular measurement of the train wheel. It also allows the laser rangefinder 12 to be stored in the measuring table 1 and protected.

[0034] A safety pin 35 is slidably connected in the through hole on the surface of the push rod 28, which can fix the position of the stored laser rangefinder 12.

[0035] Both ends of the safety pin 35 pass through the push rod 28 and extend to the outside of the measuring table 1, making it convenient for the operator to pull the safety pin 35.

[0036] Among them, the structure of laser rangefinder 12 is existing technology, and its working principle is a well-known technology. The appropriate model is selected according to the actual use.

[0037] Working principle and process: First, place the train wheel on the measuring platform 1, and then place the laser rangefinder 12 inside the measuring platform 1.

[0038] At this point, the operator manually pulls out the safety pin 35 to release the lock on the push rod 28. The return spring 34, which is fitted on the surface of the push rod 28, begins to function. One end of the return spring 34 is connected to the limit plate 33, and the other end is fixed inside the connecting rod 25. Under the action of the spring's elastic potential energy, the return spring 34 pushes the limit plate 33, thereby causing the push rod 28 to rise. One end of the push rod 28 passes through the connecting rod 25 and is connected to the laser rangefinder 12. As the push rod 28 rises, the measuring end of the laser rangefinder 12 gradually rises until it reaches the predetermined measuring position.

[0039] Then, the operator starts the servo motor 27 through the control panel. Since the output end of the servo motor 27 passes through the groove opened in the measuring table 1 and is connected to one end of the drive rod 24, after the servo motor 27 is started, the output shaft starts to rotate, thereby driving the drive rod 24 to rotate synchronously. When the drive rod 24 rotates, it drives the drive disk 23 in the circular groove inside the measuring table 1 to rotate together. The rack 29 connected to the surface of the drive disk 23 rotates accordingly and meshes with multiple racks 22 that are circumferentially distributed around the center point of the circular disk 21. Due to the distribution characteristics of the racks 22 and the design of the racks 29, when the drive disk 23 rotates, each meshing can push the racks 22, causing the circular disk 21 to rotate intermittently. This, in turn, drives the laser rangefinder 12 to rotate intermittently through the cross plate 26, realizing comprehensive measurement of different positions of the train wheel.

[0040] Once the laser rangefinder 12 reaches the predetermined measurement position, it begins to emit a laser beam. After the laser beam illuminates the surface of the train wheel, it is reflected back to the laser rangefinder 12. Through the built-in time measurement system, the time difference between the laser emission and reception is calculated. Based on the principle of the constancy of the speed of light, the distance between the laser rangefinder 12 and the surface of the train wheel is accurately calculated by combining the time difference and the speed of light. The measurement data is transmitted to the control system of the device in real time. The control system performs preliminary processing and storage on the received distance data to provide raw data for subsequent wear calculation. For specific operation, please refer to existing technology.

[0041] After the measurement is completed, remove the train wheel and press the laser rangefinder 12, causing the laser rangefinder 12 to drive the push rod 28 to slide downward inside the connecting rod 25, thereby stretching the reset spring 34. Then, reinsert the safety pin 35 into the through hole on the surface of the push rod 28 to fix the position of the laser rangefinder 12 and store the laser rangefinder 12 in the measuring table 1.
