Definitions

  • the object of the invention is to create a method and a device with which damage in the near-surface area of installed rails and switch components can be detected precisely, reliably and precisely and quantitatively analyzed.
  • two rails which are laid next to one another at a fixed distance, are moved with at least one probe each and the measurement signals of the probes are recorded in parallel.
  • the device achieving the object has an eddy current test probe, a location signal transmitter and a recording unit, to which the measurement signal of the probe (s) and the location signal of the location signal transmitter are transferred for simultaneous recording.
  • the probe (s) are seated on a measuring head which is guided on the rail.
  • the measuring head can slide like a sled over the rail and / or be guided on the rail or the switch component with rollers.
  • the location signal transmitter is preferably a GPS unit (Global Positioning System).
  • GPS unit Global Positioning System
  • a GPS unit that is commercially available for civil applications enables location determination with an accuracy of approx. 3 m. Once recognized, surface damage can be easily found. This enables the damage development to be tracked, the damage repair to be optimally planned and its success to be monitored. Modern quality management is possible on the rail network, and valuable knowledge can be gained for the future planning of track systems.
  • the GPS unit includes a gyro module.
  • An acceleration measurement is thus carried out, which enables the location signal to be extrapolated when the GPS signal is interrupted, e.g. B. when driving through a tunnel.
  • a variant of the device according to the invention is designed to be operated as a manual test system by a distance runner who preferably travels only a single rail with it. This comparatively complex form of testing is required for track areas that are currently not accessible to automated testing, for example switch areas.
  • Another variant of the device according to the invention is designed to be carried along by a rail-bound trolley.
  • the latter can be powered both by human muscle power and by a motor.
  • both rails on which the trolley is running are scanned.
  • variants of the device according to the invention which are designed to be carried along by a rail test train or rail grinding train.
  • a rail test train you get over the Duration of approximately one year of operation. Test data for the entire rail network.
  • the device carried by a rail grinding train helps to optimize the grinding work during operation so that a perfect surface quality of the rail is achieved with as little material removal as possible.
  • the recording unit of a device according to the invention which is carried by a rail vehicle, is provided with a displacement pulse signal by a displacement sensor relating to the rail or the switch component.
  • FIG. 1 shows the perspective view of a rail with surface damage typically to be detected
  • Fig. 2 shows the block diagram of an eddy current testing device for the
  • FIG. 3 shows the block diagram of a GPS unit belonging to the eddy current testing device.
  • FIG. 1 shows a steel railroad track with typical surface damage in the form of squats 12 and head checks 14.
  • Squats 12 are flat separations lying below the top of the rail 18, preferably running parallel to the surface.
  • Head checks 14 are oblique cracks in the area of the driving edge 16, which preferably occur in the arches on the outer rail.
  • the detection and evaluation of head checks 14 is difficult because they run into the rail 10 at an angle to the direction of travel and at a flat angle.
  • the location and the distance and the depth of the head checks 14 must be measured with an accuracy of a few meters and with millimeter precision.
  • FIG. 2 shows the block diagram of an eddy current test device used for this purpose.
  • This includes an eddy current test probe 20, which lies opposite the driving edge 16 and scans the rail 10 according to the magnetic induction method, in order to detect and evaluate head checks 14.
  • the probe 20 is connected to a multi-channel eddy current tester 22. Each additional channel can be occupied by another probe, not shown, which e.g. scans the top 18 of the rail 10 on squats 12.
  • the eddy current test device can be located on a rail test train that drives a pair of rails to be examined.
  • a displacement pulse signal 24 is obtained from a displacement sensor.
  • a GPS unit 26 (Global Positioning System) delivers with a current uncertainty of approx. 3 m location coordinates.
  • the GPS unit 26 includes an antenna 28, a decoder 30 and a gyromodule 32, to which the path pulse signal 24 is present.
  • the gyromodule 32 is used to extrapolate the location when the GPS reception is interrupted, for example when driving through a tunnel.
  • the output signal of the eddy current test device 22, the displacement pulse signal 24 and the location signal are applied to a PC 34.
  • the signals undergo analog-to-digital conversion 36 and online data processing, and are stored on a hard disk 38.
  • Table 1 contains information on the data flow at different driving speeds. When evaluating 6 channels of 12 bits, the current version has a data flow of 1 megabyte / s and a memory requirement of 3.6 gigabytes / h.

Abstract

L'invention concerne des rails (10) ou des éléments d'aiguillage balayés par une ou plusieurs sondes à courants de Foucault (20) dont le signal de mesure est enregistré en fonction du lieu. Cette (ces) sonde(s) (20) repose(nt) sur une tête de mesure installée en première position sur ledit rail (10). Une unité GPS (26) équipée du module gyroscopique (32) sert également d'émetteur de signal local.
