FTLY-4 Laser rail wheel inspection instrument

Instrument overview

The wheel set is an important running component of railway vehicles and plays a key role in the safe transportation of railways. After the wheels have been in operation for a period of time, defects such as abrasion, peeling, and wear will occur on the tread surface. Therefore, it is very important to accurately detect the wear condition of the wheels. The handheld laser flange measuring instrument uses high-precision laser sensors imported from Germany as the measuring sensor, which can quickly measure the flange thickness, height, tread surface and the full-size dimensions of the contour surface. It automatically stores measurement data and displays the measurement results in full digital format. The data can be uploaded to a computer to generate a database, and the post-processing software can be used to comprehensively manage the flanges digitally. It is an ideal tool for manufacturing locomotive wheel sets, maintenance and testing of subways, railway locomotive depots and vehicle depots. Its features of being compact, fast, convenient, easy to operate and high measurement accuracy have filled the gap in domestic flange measuring instruments. The instrument has passed the trial use of Xi'an Railway Bureau and the appraisal of relevant departments, and has been widely promoted and unanimously praised.

Detection principle

The handheld flange measuring instrument uses a laser reflection sensor as the measuring device, which can record the entire flange data. The entire flange contour curve can be obtained through the microprocessor, and then the flange width, flange height, 70mm wear amount, tread wear area and other parameters can be calculated. The measured data can be uploaded to a computer to generate a database, which is convenient for the digital management of wheel sets.

Product features

1. Adopt high-precision laser sensors imported from Germany.

2. Measure the flange thickness, flange height, flange tread and the full-size dimensions of the flange contour surface.

3. Automatic detection, no manual reading and recording required, reducing human errors.

4. The measurement results are displayed in full digital format, no manual conversion required.

5. Detected based on the principle of photoelectric conversion, not restricted by on-site environment and climate, with strong adaptability.

6. The detection accuracy and measuring range are suitable for on-site and online detection of all types of train wheel sets (passenger cars, freight cars, EMUs).

7. Save labor, measure multiple parameters at one time. It takes about 10-25 seconds to detect one wheel disc, which can greatly reduce the measurement labor intensity of workers.

8. The instrument is simple and practical, easy to operate, suitable for ordinary workers to use.

9. Communicate with the computer through the RS232 interface, transmit the measured data to the computer, generate reports through post-processing software, which is convenient for scientific management and realizes informatization and digitization.

10. Small size, light weight, easy to carry and use.

Application fields

1. Used for daily inspection and maintenance of wheel sets.

2. Used for dimensional measurement and qualified sorting during the wheel manufacturing process.

3. Provide flange size data for wheel refurbishment.

4. Used for the digital management of train flanges by wheel set management departments.
