Definitions

  • the invention relates to a method for testing and assessing a geometry of track components of rail traffic routes in an area in which these track components are touched by wheels of rail vehicles, a so-called. Overflow geometry.
  • track components - such as frogs in points
  • rail extensions o.ä. - be subjected to a regular inspection and, if necessary, a repair with regard to their geometric condition, so that further damage or failure of the component can be ruled out until the subsequent inspection.
  • Deviations from a given target geometry for example, extensions on the frog and wing rail
  • a check of the overflow geometry comprises only a check and evaluation of a frog ramp and a frog point 7 using simple measuring means (ruler, wedge or point probe).
  • 1a shows the use of a measuring point probe 9, FIG. 1b of a ruler 10 and FIG. 1c of a heart gauge 11.
  • the disadvantage of these measuring methods is that they are inaccurate, time-consuming and heavily influenced by the subjective influences of operating and evaluating personnel.
  • a mobile device for measuring a track position ie the altitude and the track width of a track
  • a chassis frame rolls over the track on a total of three track rollers or wheels.
  • the height of the track is determined by means of a mounted on the chassis frame theodolites, the gauge via an adjustable boom of the chassis frame.
  • a test and assessment of a geometry of individual track components is not possible with this device. It is therefore an object of the invention to provide a method with which the disadvantages of the prior art in the assessment of the overflow geometry of track components are solved. This object is achieved in connection with the preamble of the main claim according to the invention by the features specified in claim 1.
  • the spatial course of the trajectory of a wheel provided with a reference wheel profile when rolling over the respective track component in a spatially fixed coordinate system is determined directly or indirectly and then evaluated with regard to its dynamic effects.
  • the advantage here is that the validity of the test of the geometric state by the inventive determination of the vertical movement of a component rolling over the wheel in a spatially fixed coordinate system and their subsequent computer-aided evaluation significantly improved and objectified.
  • a higher than the prior art measurement accuracy is achieved at the same time higher measurement speed.
  • the entire area of the design-related lowering and subsequent lifting of the wheel (wing rail bend to K point) is continuously recorded and assessed.
  • a state of wear of wheels of rail vehicles is determined by the spatial profile of the trajectory of the respective wheel when rolling over a reference track component in a spatially fixed coordinate system directly or indirectly determined and then assessed for its dynamic effects.
  • the state of wear of wheels of measuring means can also advantageously be determined, which are moved via a track body, in particular of the wheel provided with the reference wheel profile of claim 1.
  • the inventive determination of the vertical trajectory of the wheel is carried out using a suitable Referenzradprofils that is performed in a defined position (eg Radsatzffenwolf somehow) on the component.
  • a measurement of the transverse profiles of the track component is carried out with subsequent calculation of the vertical movement of the reference wheel.
  • the measured transverse profiles must necessarily be specified in a common space-fixed reference system. This can be ensured, for example, by a measuring frame oriented parallel to the track plane, on which a profile measuring device which can be displaced in the longitudinal direction is placed.
  • an optical measurement of the transverse profiles by means of laser light section from a moving vehicle is conceivable.
  • the fixed spatial reference for example, by the combination of profiling with an inertial (gyro) can be produced. The position of the moving measuring system in the room is continuously determined and recorded.
  • a first particularly advantageous embodiment relates to a direct mechanical scanning of the geometry of the track.
  • a measuring roller 1 which is movable vertically and horizontally in a measuring base 2 aligned parallel to the track plane is guided with the shape of the reference wheel profile over the area of the possible vertical lowering 3.
  • the lowering of the measuring roller 1 on the taxiway 4 is continuously recorded and subsequently evaluated using an evaluation software.
  • a second embodiment relates to a profile measurement and subsequent calculation of the vertical wheel movement with an indirect method.
  • a measurement of the transverse profiles of the track component is carried out with subsequent calculation of the vertical movement of the reference wheel.
  • the measured transverse profiles must necessarily be specified in a common space-fixed reference system. This can be ensured, for example, by a measuring frame oriented parallel to the track plane, on which a profile measuring device which can be displaced in the longitudinal direction is placed.
  • an optical measurement of the transverse profiles by means of laser light section from the moving vehicle is conceivable.
  • the fixed spatial reference for example, by the combination of profiling with an inertial (gyro) can be produced. The position of the moving measuring system in the room is continuously determined and recorded.
