OKOSCAN UT 73HS PICKUP is a high-speed ultrasonic testing system for rails with testing speed of up to 40 km/h (24.85 mph) which is installed onto the customer`s vehicle (based on Ford F350 XL (SUPER DUTY) with combined course car.
The System consists of:
a) an ultrasonic trolley which moves behind the vehicle in testing mode and monitors the changes in the track gauge (track width) with the extending/retracting pneumatic system oftrolley decompression
b) equipment installed in the vehicle body (UT channels, automation and control box, hydraulic station, air compressor, container for coupling liquid, water supply system, hydraulic system for lifting and lowering the trolley). The operator's workplace with control monitors is located at the rear seat in the vehicle cabin.
-
The trolley equipment:
- 4 roller immersion search unit (RSUI) (2 pcs on each side of the trolley)
Each unit includes:
- 0° probe, 4 MHz – 1 pc
- 70° probe, 2 MHz – 3 pcs
- 50° probe (side looking), 2 MHz – 1 pc
- 37° probe, 2 MHz – 1 pc
- Positioning system of RSUI using stepper electric drives, guided by operator (lifting/lowering, transverse displacement, tilt; operator-guided).
- extending/retracting pneumatic system of trolley allows to monitor the track gauge and thereby position RSUI along the rail axis.
- Encoder for tracking the path coordinates.
- Video surveillance system of probe units.
- Water supply system for RSUI (manual adjustment taps, tubes, nozzles)
-
The vehicle body includes:
- Ultrasonic modules OKO-24 (at least 24 pcs) with frequency range from 1 to 7 MHz and pulsory repetition frequency (PRF) of up to 4 kHz.
- Automation and control boxes
- Trolley lifting and lowering system with hydraulic station
- Air compressor for extending/retracting pneumatic system of trolley
- Water supply system under RSUI
-
OKOSCAN UT 73 HS features:
- The trolley performs continuous ultrasonic testing (UT) of double-rail track along the whole length and cross-section, except for rail foot flanges at a speed of up to 40km/h (24.85 mph)
- The gauge of the track under testing is 1435 – 1676 mm (can be changed at the Buyer`s request)
- The system allows detecting all types of defects: transverse and longitudinal horizontal cracks, cracks from bolt holes, etc. according to AREMA listing.
- The system measures defect parameters and saves inspection results to the database with the possibility of subsequent viewing and analysis.
- The System implements the following ultrasonic testing methods: pulse-echo and echo-shadow techniques.
-
OKOSCAN UT 73 HS’s hardware and computing system:
Equipment for processing and inspection results visualization is located at the operator’s workplace in the vehicle cabin.
The equipment provides for collection of inspection results data, visualization in various modes (A-scan, B-scan), generation of inspection reports, and the possibility of inspection results transmition through mobile operators via the 3G/4G protocol.
-
Pre-installed Software ensures the following functions:
- Automatic defect identification and their classification.
- UT control channels settings (gain, sweep parameters, RFC, probe parameters, gates parameters) and saving settings in storage.
- Inspection results visualization simultaneously in B-scan and A-scan modes for all channels in real time.
- Starting coordinate registration, inspection area data registration, track data registration.
- Viewing inspection results data with the possibility to implement all standard database management system functions (sorting and sampling according to agreed parameters).
- Formation of inspection protocols (also in Excel format).
- Memory capacity (HDD) allows you to save inspection results of at least 10,000 km of testing
- Automatic linking of the detected defect to path and GPS coordinates.
