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
  • an overflow geometry test involves only a test and assessment of a frog ramp and a frog tip 7 using simple measuring instruments (ruler, measuring wedge or measuring point probe).
  • Fig. 1a the use of a measuring point probe 9, Fig. 1b of a ruler 10 as well Fig. 1c
  • a height difference between the top edge of the frog and a wing rail 6 in a cross section "L1", a theoretical wheel overflow, and "L” is measured by means of a heart gauge.
  • 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.
  • Out DE 24 60 618 A1 is a mobile device for measuring a track position, ie the altitude and the track width of a track, known.
  • 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 track geometry measurement is known in which a sensor-based online detection system with evaluation of wheel and track-related data during a train journey by interpretation of the measured values is used with the aid of temporal and geometric correlation analysis ( DE 198 27 271 A1 ).
  • As part of this track geometry measurement no determination of the actual movement of the wheel is performed.
  • the contact geometry between wheel and rail which significantly influences the trajectory, in particular when driving over a turnout or a rail extension, is not determined.
  • 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 in terms of 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.
  • intervention thresholds for the repair must be specified for these variables, see Fig. 2 .
  • the concrete definition of intervention thresholds is influenced by numerous constraints and must be based on a technical and economic analysis by the infrastructure manager. Claim 2 includes a reciprocal to claim 1 method.
  • 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 member in a spatially fixed coordinate system directly or indirectly determined and then evaluated in terms of its dynamic effects.
  • the state of wear of wheels can also advantageously be determined by measuring means which are moved via a track body, in particular by 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 oriented parallel to the track plane and having the shape of the reference wheel profile is guided 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, be produced by combining the profiling with an inertial (gyro platform). The position of the moving measuring system in the room is continuously determined and recorded. With the help of this information, a transformation of the measured transverse profiles into the track level is then carried out.
  • the smallest possible sampling interval is generally to be selected in order to obtain a realistic trajectory of the center of gravity of the wheel.
  • a contact geometric calculation is carried out, in which the vertical position of the wheel is determined for each measuring cross section.
  • the vertical trajectory of the wheel which is now available for further evaluation. If the number or density of the measuring cross-sections is not sufficient to determine the trajectory of the wheel sufficiently accurately, the evaluation can also be carried out for additional interpolated cross-sections.
