Railway Wheel Inspection Instrument (Wheel Tread Profile Tester)

FTLY-4Laser Railway Wheel Inspection Instrument

Instrument Overview

The wheelset, as a critical running component of railway vehicles, plays a key role in the safe transportation of railways. After a period of operation, the wheel tread may develop defects such as scratches, spalling, and wear. Therefore, accurately detecting the wear condition of wheels is very important. The laser handheld wheel flange measuring instrument uses a high-precision laser sensor imported from Germany as the measuring sensor, enabling rapid measurement of flange thickness, height, tread, and full-profile dimensions. It automatically stores measurement data and displays results in full digital format. Data can be uploaded to a computer to generate a database, and through post-processing software, comprehensive digital management of the wheel flange can be achieved. It is an ideal tool for the manufacturing of locomotive wheelsets, subway systems, railway depots, and maintenance and inspection in rolling stock depots. Its compact size, speed, convenience, ease of operation, and high measurement accuracy fill the gap in domestic wheel flange measuring instruments. The instrument has passed trials by the Xi'an Railway Bureau and certification by relevant departments, receiving widespread promotion and unanimous praise.

Inspection Principle

The handheld wheel flange measuring instrument uses a laser reflective sensor as the measuring device, capable of recording the entire wheel flange data. The microprocessor can derive the entire wheel flange profile curve, thereby obtaining the flange width, flange height, 70mm wear amount, and tread wear area. Additionally, the measured data can be uploaded to a computer to generate a database, facilitating digital management of the wheelset.

Product Features

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

2. Measures flange thickness, flange height, wheel tread, and full-profile dimensions of the wheel flange.

3. Automatic detection eliminates manual reading and recording, reducing human error.

4. Fully digital display of measurement results, eliminating the need for manual conversion.

5. Detection based on photoelectric conversion principle, unaffected by on-site environment and climate, with strong adaptability.

6. Detection accuracy and range are suitable for on-site and online inspection of all types of railway wheelsets (passenger cars, freight cars, and electric multiple units).

7. Reduces labor by measuring multiple parameters in one go. Approximately 10-25 seconds per wheel disc, significantly reducing the measurement workload for workers.

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

9. Communicates with computers via RS232 interface, allowing measured data to be transferred to a computer for report generation through post-processing software, facilitating scientific management and enabling informatization and digitization.

10. Compact size, lightweight, and easy to carry and use.
