Definitions

  • the present invention relates to a device for testing rails, especially railroad tracks, but also tram and subway rails and the like for hidden defects such as cracks.
  • Known rail testing devices are incorporated in rail test trains, such as the applicant's UST96 ultrasonic rail test train. They are used to detect hidden defects in rails, such as cracks and the like.
  • the test is performed with ultrasound, which is introduced by means of a test device from above the rail in this.
  • the ultrasound is reflected at the bottom of the rail and gives a response signal in the tester. If there are cracks, the reflection of the ultrasound takes place earlier, namely between the top of the rail and the underside of the rail. The response signal is therefore different and can be detected and analyzed.
  • eddy current tests of the rails are carried out. Again, this can be done with such Schienenprüfmann.
  • the measuring data of the probes are transmitted to a control computer, where further data such as GPS and displacement information are collected.
  • a pre-selection of surface damage events takes place by means of a special evaluation software. All measured data are subject to direct evaluation here.
  • a detailed evaluation by a computer done off-line. The displays are displayed on the screen as amplitudes above the track.
  • the measurements are carried out at speeds of up to 100 km / h.
  • the vehicle is equipped with state-of-the-art measuring and computer technology.
  • sixteen guided probes "see" each rail at different angles into the rails. Of course, a different number of probes can be used.
  • the control electronics ensure a permanent optimization of the signal levels. Rail profiles are automatically taken into account during optimization.
  • the test data of the test channels are processed directly by means of evaluation software and displayed on the display of the test system.
  • the rail test trains comprise measuring bogies, with pairs of wheels spread apart, i. be pressed by means of force against the rail inner edges. This ensures that the wheels are always in the same position relative to the associated rail.
  • the position of the test device is thus determined transversely to the rail longitudinal direction, so that it can be ensured that the ultrasound test takes place at the intended position, namely in the region of the rail web and its extension into the rail head and the rail foot. Only this ensures that the ultrasound runs through the entire rail and is only reflected on its underside, provided that no damage is present.
  • This embodiment of the Schienenprüfman also has the disadvantage that false triggering of railway signals due to the track release means in the rails occur. Since different counting principles exist, it is difficult to avoid false axis counts and thus false tripping. As a result, serious consequences, including road closures, are known to arise, the removal of which requires the use of the Federal Border police.
  • the invention is therefore based on the object to avoid these problems.
  • an improved rail inspection device should be specified.
  • a device according to the preamble of claim 1, characterized in that the device is at least substantially rigidly connected to at least one axis of the rail vehicle and supported by this or these axes.
  • test apparatus Unlike known testers this is therefore not on the car body or bogie and thus not resiliently supported, but is supported by the axles, which are not sprung against the rail are. As a result, the test apparatus has an unambiguous position relative to the upper edge of the rail, so that no falsification of the measurement results occurs.
  • a slightly resilient mounting of the test apparatus relative to the axes is basically possible, as long as it is ensured that the permitted relative movement does not lead to any falsification of the measurement results. However, a completely rigid connection is preferred.
  • the test device is suspended in particular on laterally outwardly projecting portions of the wheel axles on this. This has proven to be particularly advantageous for the arrangement of the test apparatus. In principle, however, a suspension would be possible in an axle area located between the wheels.
  • the test device according to the invention preferably comprises a frame, which carries the measuring devices and in turn is rigidly connected to at least one wheel axle. Above the frame, the measuring devices can be worn in a suitable manner.
  • the frame can also accommodate several measuring devices.
  • test device is suspended on two adjacent wheel axles and preferably has a torsion compensation device. This results in a suspension at four points, which is particularly stable. About the torsion compensation device can be prevented that the tester changes the torsional properties of the bogie.
  • test apparatus are arranged one behind the other in the rail longitudinal direction, in particular also different test apparatuses, such as ultrasonic testing apparatus, from one another and inductive testing device, for example eddy current testing device. Due to the suspension of the testers on the wheel axles so much space is gained over known testers that two testers can be easily arranged in the longitudinal direction one behind the other. This allows two different measurements to be carried out simultaneously with a single measuring bogie.
  • test apparatuses such as ultrasonic testing apparatus
  • the measuring devices of the test device according to the invention are preferably mounted displaceably transversely to the rail longitudinal direction, in particular with respect to the frame. This can ensure that the measuring devices are in the optimum position to the rail to perform the measurements.
  • the adjustment of the measuring devices can be done for example by stepper motors and regulated in a known manner.
  • test apparatus on measuring devices, which are mounted transversely to the longitudinal extent of the rails displaceable, wherein means are provided for positioning the measuring devices relative to the rail, which operate without contact with the rail.
  • This slidable bearing and positioning device can also be used in conventional test devices, in which the test device is suspended on the bogie or on the car body. In this case, however, dispenses with the spreading of the pairs of wheels and instead determines the position of the test apparatus, in particular the wheels of the measuring bogie relative to the rail. About a control device, the position of the tester can be adjusted in the desired manner, for example, again on stepper motors or the like.
  • the test apparatus has, in particular, means for positioning the measuring head, means for measuring the distance between the measuring head and the rail, and means for moving the measuring head relative to the rail. The distance measurement can be carried out by means of laser, radar, eddy current, ultrasound or mechanical.
  • the invention has the advantage that no Aufsp Rudsch must be provided and that the disadvantages associated with the spreading no longer occur. In particular, turnouts can be run over easily, and there is no derailment required.
  • the invention can be developed in particular by the fact that the wheels are made of plastic and / or have no flange. Incorrect axle counting can be avoided by the use of plastic, and the absence of a flange on the wheels in turn increases the derailment of the device when driving over turnouts.
  • An inventive Schienenprüfzug may have a plurality of such Schienenprüfvorraumen.
  • several pairs of such rail test devices may be provided with one test device for each rail.
  • two pairs can be arranged on a frame with two pairs of wheels and two or more racks in a row be present.
  • the distance measurement takes place between the rail and the associated testing device itself or a part of the rail testing device rigidly connected thereto, preferably the associated wheel of the rail testing device, so that in each case the relative position between rail and associated testing device can be determined.
  • the Measurement can be carried out by laser, radar, eddy current, mechanical means, ultrasound or in any other way.
  • the measurement can be continuous or at intervals.
  • the adjustment of the wheels and thus the test apparatus relative to the rail in a known manner, for example by servo motors.
  • the rail inspection device according to the invention can also be integrated in a normal bogie.
  • the distance can also be measured by providing means by which a laser cutting profile of the rail can be created, means for detecting the rail type based on the cutting profile, means for measuring a point on the rail and means for determining the position of the rail web based on these data , On the basis of the determined laser cutting profile, the rail type can be determined. The position of the bar can then be determined with the help of the rail type and the measured point.
  • Another possibility is to detect two corner points of the rail head and to determine the position of the rail web over the average value of the distances of the two corner points.
  • the means for positioning the measuring devices are preferably arranged at a distance from the measuring devices themselves. As a result, a disturbance of the distance measurement can be avoided by the rail inspection. For example, in ultrasonic measurements, a water film is used which would interfere with a distance laser measurement.
  • a laser triangulation measurement or a laser phase displacement measurement may be performed, in which the laser is directed to a rail edge.
  • rapid changes in the distance can be detected a change or a different distance in a front region and a rear region of the test device can be determined.
  • Stellstellsysteme can compensate for such a difference.
  • a so-called line-scan camera is sufficient for recording the triangulation points.
  • a not shown in the drawing rail vehicle has a bogie 1, which may be designed as a special measuring bogie, but need not.
  • the bogie comprises two axles 2, each carrying in a known manner two wheels 3, which roll on rails 4 of a track.
  • a chassis receptacle 5 is arranged, which is supported on the axles 2 via damping and spring devices 6. Also supported by the axles 2 is a frame 7 which, however, is not resiliently supported relative to the axles 2 but is at least substantially rigidly connected thereto.
  • the frame 7 carried by the axles 2 in turn carries two testing devices 8 which are arranged one behind the other in the rail longitudinal direction and spaced from each other.
  • Each of the rail testers 8 constitutes its own test system, and the type of test between the two rail testers 8 may be different. Of course, too only one rail inspection device 8 or more than two rail inspection devices 8 may be arranged on the frame 7.
  • the rail testing devices 8 are connected in a manner not shown transversely to the longitudinal direction of the rails 4 slidably connected to the frame 7.
  • the test devices can therefore be brought into a suitable position with respect to the transverse direction of the rails. This can ensure that, for example, an ultrasonic measurement in the region of the web 10 of the rails 4 takes place.
  • a distance measurement can be used.
  • the distance measurement is carried out in particular contactless, for example by means of laser, radar, eddy current, ultrasound or mechanical.
  • Particularly preferred is a distance determination on the creation of a laser cutting profile and recognize the rail type.
