Non-destructive testing

Mobile diagnostic complex

Complex reliable inspection up to 250 km of the rail track during one inspection with speed of up to 60 kmh based on 6 non-destructive inspection systems.

  • Ultrasonic inspection

  • Magnetic inspection

  • Testing geometric parameters of track line

  • Testing geometric parameters of railhead profile

  • Video inspection of the rail and braces condition

  • Measurement rail irregularities by inertial methods


Main benefits of MDC

 

High reliability of detecting rail’s defects:

  • 24 channel ultrasonic scheme with four methods of ultrasonic inspection and patented inspection modes;

  • defects detection under the surface of the railhead by magnetic channel at temperature - 50ºC;

  • complex analysis of diagnostic information by acoustic and magnetic defectogram and video frames;

  • localization sectors of the track with corrosion damage of the rail foot;

  • contactless (magnetic) alignment of inspection system concerning to rail longitudinal axis.


Video reporting of rail’s elements:

  • different types of cameras for video documentation of rails condition, rail braces, bolted and welded joints and elements of track switches (speed of up to 65 kmh);

  • high quality of image due to economical flash  lighting of camera and system of protective shutters at any climatic conditions;

  • program regulation of brightness additional lighting, also directions of review and optical zoom of operated video cameras;

  • video information transmission for future monitoring of rail track condition and infrastructure facilities.


Automation of handling diagnostic information:

  • output of information processing results of the track geometry control system with determination of  deviation from the standards;

  • synchronization of the inspection signals with video information;

  • automatic defining bolted, isolated and welded joints, track switches with protocol generation;

  • automatic determination gap’s value of bolted joint;

  • synchronic analysis of current and previous inspection (monitoring of the developing flaws and rail’s condition);

  • automatic search of the track’s sections with absence acoustic contact;

  • recoding of inspection protocol, telegrams for the purpose of changing of high defective rails and subsequent transmission it via GPRS from the car.


Minimization of maintains expanses:

  • contactless sensors for measurement geometry of rail track geometry;

  • contactless (magnetic) alignment of the inspection system concerning to rail longitudinal axis;

  • electro drive for moving up/down measure;

  • pneumatic drive of moving up/down of inspection system;

  • displaying an information about consumption and temperature of couplant;

  • two cameras for looking after the inspection system during testing;

  • comfortable living and working conditions of the crew.
