Definitions

  • the invention relates to a device for temperature detection according to the preamble of claim 1.
  • measuring geometries are used whose inclination angle> Is 90 °. These orders require at least an additional track switching device to limit the Measuring range.
  • the specified measuring points can only be reached, e.g. Magnetic track or eddy current brakes not lowered, i.e. not in Are braking position.
  • the measuring geometry of the scanning systems can be such arrangements by vibration or mechanical Blows, e.g. by drooping vehicle and / or load parts change unnoticed what to significant operational risks.
  • the cable connections are at these superstructures are usually laid on the superstructure, in order to avoid cables even when the ground is frozen to enable exchange. Damage to this electrical connections are therefore relatively common.
  • Touch voltages can be used in the previously used rail-mounted measuring systems with 220 V are supplied, and for routes that have track circuit free notification are equipped only by the electrical Connection of a scanner to the respective rail will be realized.
  • the earth connection is disconnected and Live infrared scanner housing can be used for the maintenance personnel are at risk of death.
  • the invention is based on the object Overcome disadvantages and specify a facility with the any wheelset and / or vehicle part with the shortest possible measuring distance can be monitored, their measuring systems at each Place parallel to the threshold, i.e. also between the Rails can be arranged, their measurement geometries unchangeable and their measuring systems neither are mechanically influenced electrically.
  • the device according to the invention stands out characterized in that by suitably arranged deflection units the individual infrared sources of each vehicle and / or wheel set scanned several times in parallel and the infrared radiation in total in parallel fed to one or more infrared receiver units becomes.
  • the device is housed in a hollow track sleeper in parallel is arranged to the track sleepers.
  • the individual deflection units are with or equipped with several locking units, through which the infrared radiation reaches the deflection unit.
  • the infrared radiation can be deflected by the latter and / or clocked and / or hidden.
  • the one in the hollow track sleeper arranged infrared receiving unit can receive multiple signals and if necessary link together. Due to the relatively large Distance to the rails and due to the electrical Shielding by the supporting metal profile is the electromagnetic influence of this receiving unit reduced to a minimum. All supply and data lines are through the Metal profile electrically and mechanically protected.
  • the threshold on the rail installed devices for recording the wheel support pressure and the acceleration of the rail or the threshold in the direction perpendicular to the longitudinal axis of the rail can determine the exact wheel position and thus the measuring range parallel to the track axis from Ache Axis determined and set and the measured values in one downstream evaluation unit may be corrected.
  • the temperature values are thus on the evaluation unit all wheelset components and various vehicle components, total wheelset weight, as well as the wheel loads available.
  • measurement variables are available, which is also related to the condition of the wheel Imbalance and tread damage, which is a cause for bearing damage, provide information.
  • Fig.1 is between two track sleepers 2 one Hollow track sleeper 11 shown, in which both the deflection units 9 and the IR receiving unit 15 housed are. In addition, in Fig.1 are still Closure units 9a to recognize the Deflection units are covered.
  • Fig.2 shows on the carried by the sleepers 2 Rails 1 a wheel set consisting of the wheels 4, the wheelset shaft 6 and the wheelset bearings 5.
  • the wheelset shaft 6 also carries the drive motor 3.
  • the accelerometers are on the two rails 1 7 attached, from which cable connections 7a to a not shown Lead evaluation unit.
