LDM ROAD-RAIL NDT INSPECTION MOBILE LABORATORY

Transcription

1 LDM-LR version of the laboratory is equipped with a device which is intended for quick switching from the rail track with mm gauge to the general European track with 1435 mm gauge. This feature makes it possible to employ the laboratory on almost all railways of Europe and Asia. LDM laboratory provides logging and documenting of raw inspection data and the results of their processing, as well as realtime presentation of the acquired information. All logging and documenting functions are performed by CRUISE-M or CRUISE-2 system (depending on LDM version). LDM ROAD-RAIL NDT INSPECTION MOBILE LABORATORY The sophisticated design of the probe system provides precise positioning of the probe system on the rail head, reduces the risk of the system damage at the switches, and ensures increased inspection speed. Furthermore, the ultrasonic units of the probe system are unified with the ultrasonic units of the NDT vehicles. On customer s request, LDM-1-P and LDM-1-DPG versions of the laboratory, apart from the NDT system, may be additionally equipped with the track geometry and georadar systems manufactured by TVEMA. The rail track geometry system employed on LDM-1-P uses TRACK software which is intended for collection, processing and logging of data acquired during the railway track inspection. The software provides the display of the track geometry data with the diagrams. LDM-1-P version of the laboratory uses the georadar system which detects the location of the roadbed soil upper level and its lithologic structure, and it locates in the roadbed weakened areas having reduced density and increased humidity. In addition, it locates areas hosting engineering facilities and detects areas with laid geotextile and styrene foam shields. LDMs are equipped with the road-rail traffic safety system. The operation of LDM-LR version of the laboratory based on the all-road car LAND ROVER Defender was successfully demonstrated in 2012 on the test section in Kirchmoser, Germany, and receive positive feedback from the German colleagues. LDM road-rail NDT inspection mobile laboratory is a reworked all-road car UAZ-3163 Patriot (LDM-1) or LAND ROVER Defender (LDM-LR), which is known for high mobility and excellent crosscountry ability. Due to road-rail equipment, the laboratory may travel not only on roads (motorways, cross-country terrain), but also on railway tracks. The sophisticated design of the probe system provides the most advanced ultrasonic checking patterns. LDM road-rail NDT inspection mobile laboratory is intended for continuous rail monitoring, for diagnostics and inspection of defects according to NTD/TsP-1-93 and UIC rail defect classifiers, using data processing systems at a speed of up to km/h. In the course of its travel, the laboratory also logs the parameters of the railway track section under inspection (coordinates of kilometre posts, crossings, switches, etc.). It generates and transmits the information on railway track condition to respective responsible facilities for their further operation. For the railways of Russia and CIS countries the laboratory provides diagnostics, rating, monitoring for rail types R50, R65, R75 laid in a railway track with, 1435, 1676 mm gauge. It also provides defect detection for the rails which sizes, material and content conforms to: GOST , GOST , GOST , GOST , GOST 16-77, and GOST Mass of detachable implements, kg, not more than Number of seats, not less than Roller guide tread diameter, mm Number of ultrasonic channels, not less than Sounding pulse amplitude, Hz Sounding pulse frequency, Hz Operation frequency of PZT, MHz Basic relative error for measuring the travel, % Warm-up time, min, not more than Maximum inspection speed, km/h Maximum transport speed, km/h Contact liquid stock, m³, not less than value ± * (18) ± * Depending on the type of NDT analyzer installed

2 MRK-1 road-rail mobile rail lubricator comprises: operator s workstation; rail lubrication assembly. The rail lubrication assembly comprises the systems for: lubricant filling; lubricant storage; lubricant supply to the nozzles with GPS/ GLONASS control unit; lubricant supply onto the rails; video monitoring and logging of the lubrication process. MRK-1 ROAD-RAIL MOBILE RAIL LUBRICATOR MRK-1 road-rail mobile rail lubricator is a reworked all-road car UAZ Patriot. MRK-1 road-rail mobile rail lubricator is intended for the lubrication of switches, frogs, and rails in the curves of the station and low-density railway tracks where the use of the rail lubrication vehicles is impractical and economically inefficient. The car is a unique high-tech rail lubrication system of a new generation, previously mounted only on the carriages. The highest performance of the system based on the intellectual control substantially saves the material and human resources, as well as the time for the rail lubrication which is the crucial process for increasing the lifetime of the carriage wheels and the railway track and for providing the safety of the railway traffic. The superior energy saving effect of the rail lubricator means that the specific consumption of the lubricant does not exceed 0.35 litres per 1 km of the curved rail, irrespective of the travel speed. Another feature of the system that makes it different from other existing lubrication solutions is the minimized environmental impact. This is the unrivalled system.

3 LDM-2M ROAD-RAIL SHUNTING CAR LDM-2M road-rail shunting car, produced in 2013 by TVEMA, is an economic and effective alternative to expensive (both price and operation) shunting locomotives of the light and middle class. This car is built on the basis of an all-road car UAZ 2363 Pickup is furnished with dedicated equipment to perform a wide range of shunting operations at the stations and spur tracks including movement of carriages (locomotives), haulage of carriages to the loading areas and repair tracks, their shifting between parks. Due to the road-rail system which comprises automotive chassis and roller guides LDM-2M can travel both on roads of different categories (including cross-country terrain), and on railway tracks with various gauge values (1435,, 1670 mm). The rail-road system is controlled by the pneumatic circuit which supplies air to the suspension cylinders. Traffic safety system LDM-2M like other rail-road cars has a unique traffic safety system. The system features auto-stop braking and navigation in GLONASS/GPS coordinates. It constantly controls the car speed and the driver s vigilance. When the actual speed reaches the allowed value, the warning light and sound alarm is switched on. Unless the driver responds appropriately, emergency braking occurs. LDM-2M comprises: device for travelling on railway tracks; shunting device; fixed coupler for coupling with a railway vehicle; cellular communications device; two portable radios; two-band locomotive radio for communication with a traffic controller or a station duty officer; wire telephone of haul communication; flashing beacon; device for driving on and off the railway track at places which are not equipped for this. A set of dedicated equipment for performing shunting operations comprises: driver s brake valve; compressor plant; pressure gauge; brake hose; coupler. The coupler, which is unprecedented, was designed by the TVEMA specialists specially for this vehicle.
