Definitions

  • the invention relates to a wheelset diagnostic device for monitoring passing railway vehicles according to the preamble of claim 1 for the purpose of detecting the temperatures of the wheelset shafts, their drive, braking and bearing components as well as other heat sources to be monitored on the vehicle, in particular radiation surfaces, to the thermal energy of not directly accessible Drive elements is transferred by heat conduction, or with which the temperatures of these devices are simulated.
  • measuring geometries are employed, their inclination angle> 90 °. These arrangements require at least one additional track switching device to limit the measuring range.
  • the specified measuring points can only be reached if, for example, magnetic rail or eddy current brakes are not lowered, ie are not in the braking position.
  • the measurement geometry of the scanning systems in such arrangements can change due to vibration or mechanical impacts, e.g. can change unnoticed by hanging vehicle and / or cargo parts, which can lead to considerable operational risks.
  • deflector plates must be installed, which significantly increase the maintenance effort.
  • the cable connections are usually laid on the superstructure in order to enable cable replacement even when the ground is frozen. Damage to these electrical connections is therefore relatively common.
  • the electrical safety against impermissibly high contact voltages can only be achieved with the rail-mounted measuring systems that have been used so far, which are supplied with 220 V, and with lines that are equipped with free track circuit detection by the electrical connection of a scanner to the respective rail. If the earth connection is disconnected and the infrared sensor housing is live, there may be a risk to life for the maintenance personnel.
  • the invention has for its object to overcome these disadvantages and to provide a device with which any wheelset and / or vehicle part with the shortest possible Measuring section can be monitored, the measuring systems can be arranged at any point parallel to the threshold, that is also between the rails, the measuring geometries cannot be changed and the measuring systems can be influenced neither mechanically nor electrically.
  • the device according to the invention is characterized in that the individual infrared sources of each vehicle and / or wheel set are scanned several times in parallel by means of suitably arranged deflection units and the infrared radiation as a whole is fed in parallel to one or more infrared receiver units.
  • the device can be accommodated in a measuring threshold, which is arranged parallel to the track sleepers, or in a hollow track sleeper.
  • the individual deflection units are equipped with one or more closure units through which the infrared radiation reaches the deflection unit.
  • the infrared radiation can be deflected and / or clocked and / or masked out by the latter.
  • the infrared receiving unit which is also arranged in the measuring threshold or in the hollow track threshold, can receive several signals and, if necessary, link them to one another. Due to the relatively large distance to the rails and due to the electrical shielding by the supporting metal profile, the electromagnetic influence on this receiving unit is reduced to a minimum. All supply and data lines are electrically and mechanically protected by the metal profile.
  • the exact wheel position can be determined and thus the measuring range parallel to the track axis from axis to axis can be determined and adjusted and the Measured values may be corrected in a downstream evaluation unit.
  • the temperature values of all wheel set components and various vehicle components, the total wheel set weight and the wheel loads are thus available on the evaluation unit.
  • Measured variables are available in connection with the acceleration values and the wheel pressure, which also provide information on the condition of the wheel in relation to unbalance and tread damage, which are a cause of bearing damage.
  • FIG. 1 shows a hollow track sleeper 11 between two track sleepers 2, in which both the deflection units 9 and the IR receiver unit 15 are accommodated.
  • the closure units 9a with which the deflection units are covered can also be seen in FIG.
  • the sleepers 2 shows on the rails 1 carried by the sleepers 2 a wheel set consisting of the wheels 4, the wheel set shaft 6 and the wheel set bearings 5.
  • the wheelset shaft 6 also carries the drive motor 3.
  • Accelerometers 7 are attached to the two rails 1, from which cable connections 7a lead to an evaluation unit (not shown).
  • Cables 10 emerge from the end face of the hollow track sleeper 11 and connect the receiving unit to the evaluation unit mentioned.
  • the course of the various measuring beams is indicated by means of the arrows 8.
  • all braking devices used so far e.g. Block, shaft disc and wheel disc brakes are drawn in, which are generally numbered 12.
