摘要： A method for detecting defects in a railway rail including a search unit and preferably a roller search unit (“RSU”) mounted on a test vehicle and in rolling contact with the running surface of the rails to inspect each rail. The RSU includes a tire filled with a liquid and a transducer assembly mounted within the tire. The transducer assembly includes one or more arrays of ultrasonic transducers directed toward the running surface of the rail. A laser profiler mounted on the test vehicle in combination with a linear encoder provide profile data which is communicated to a system controller to dynamically adjust the focal laws for the one or more arrays of transducers to dynamically steer the transmitted beams to produce the ideal inspection beam sets while the test vehicle is in motion.

摘要： An apparatus and method for inspecting a rail joint bar transported along a railway rail by an inspection vehicle is provided. The apparatus and method includes a pair of ultrasonic transducers housed in liquid-filled wheels. The wheels are positionable for a stored position to a measurement position in rolling contact with the vehicle surfaces of the rail joint bars on each side of the rail. The ultrasonic transducer transmits a signal into the rail joint bar and the reflected signal is detected by the transducer and analyzed to identify flaws in the rail joint bar.

摘要： An apparatus for ultrasonic inspection of an object. A tire is mounted for rolling along the surface of the object. It contains a liquid and a transducer assembly. The transducer assembly is positioned in the tire adjacent a portion of the surface of the tire in contact with the object. The liquid and the surface of the tire in contact with the object provide an acoustic bridge between the transducer assembly and the object. An electric signal processing system is connected to the transducer assembly. It generates electric signals which are converted to acoustic signals in the transducer assembly to place acoustic signals in the object. Acoustic signals returned from the object are converted to electric signals by the transducer assembly, and are processed in the electric signal processing system to indicate flaws in the object.

摘要： A roller search unit for detecting rail defects with integrated digital circuitry includes a liquid filled tire mounted to an axle assembly with wheels. An ultrasonic transducer array positioned within a housing is positioned within the within the tire and coupled to the axle. The housing contains transducer interface circuitry operable to receive analog signals from the ultrasonic transducer array and contains digital flaw detection circuitry operable to convert the analog signals to digital signals and perform analysis on the digital signals to detect flaws in a rail. The transducer interface circuitry and digital flaw detection circuitry are configured to stack to provide a compact, small footprint assembly. The conversion of the transducer signals from analog to digital within the tire permits transmission of the digitized data without susceptibility to interference and noise.

摘要： An equipment housing assembly removably securable to a hi-rail vehicle operable to advance along first and second rails of a railroad track includes a housing that houses and/or supports at least one rail sensor. The at least one rail sensor is operable to sense at least one property of at least one of the first and second rails as the hi-rail vehicle advances along the first and second rails. The at least one rail sensor is advanceable from a retracted configuration relative to the equipment housing to a deployed configuration relative to the equipment housing to sense the at least one property of at least one of the first and second rails. A power distribution system is removably and electrically connectable to a power source in the hi-rail vehicle. A control system is communicatively coupled the at least one sensor to control operation thereof and communicate sensor data therefrom.
