FTLY-4laser rail wheel tester

Instrument Overview

As an important running component of railway vehicles, wheel pairs play a key role in safe railway transportation. After a period of operation, defects such as abrasion, peeling and wear will appear on the tread of the wheels, so 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 and the full-size 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 conduct comprehensive digital management of the flange. It is an ideal tool for manufacturing locomotive wheel pairs, 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 of 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 reflective 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 and tread wear area can be calculated. The measured data can also be uploaded to a computer to generate a database, which is convenient for digital management of wheel pairs.

Product Features

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

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

3. Automatically detects without manual reading and recording, reducing human errors.

4. Displays the measurement results in full digital format without manual secondary conversion.

5. Detects based on the photoelectric conversion principle, which is not restricted by on-site environment and climate, and has strong adaptability.

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

7. Saves manpower and measures multiple parameters at one time. It takes about 10-25 seconds to detect one wheel disc, which greatly reduces the measurement labor intensity of workers.

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

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

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

Application Fields

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

2. Used for size measurement and qualified sorting during wheel manufacturing.

3. Provides flange size data for wheel refurbishment.

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

5. Can be conveniently installed on wheel pair production lines for size control during wheel pair production.

6.Detection of subway vehicle wheel pairs.
