Description

The invention relates to a method for track position correction, wherein the track under lifting into a provisional target position and subsequently in the Frame of a track stabilization by applying a static load in Connection with transverse vibrations finally controlled in a final Desired position is lowered.

Through the magazine "Railway Track & Structures", 3/96, pages 29 - 33, is described such a method for track position correction. A required, so-called "mechanical processing train" (MDZ) sits down in this case from a heavy duty tamping machine, a ballast plow and a following in the direction of track stabilizer together. This work unit, formed of three vehicles, is in operation continuous process, whereby by the tamping the track in one correct provisional target position brought and then according to regulations is swallowed up. Finally, the track is applied by applying a static Overload in connection with horizontal transverse vibrations by the Track stabilizer controlled lowered into a final target position.

The object of the present invention is now to provide a method for track position correction of the type described above, with a improved track position is achievable.

This object is achieved according to the invention with a method of the generic type Art solved by the fact that created with the Unterstopfen of the track measured provisional target position and a long-wave track position error eliminating, final target position is calculated, then under determination of correction values as the difference between the final target position and preliminary target position in the context of a track stabilization one the correction values corresponding change of static load and / or of acting on the track lateral forces to achieve the final target position of the track.

The inventive method is based on the consideration that the Gleisstopfen following track stabilizers for the artificial anticipation of Initial settlements at the same time also for a final correction possibly existing, in particular long-wave track position error use. For this purpose the preliminary present immediately after the blockage becomes Desired position of the track expediently by the machine's own reference system the tamping machine is measured to with the help of an electronic Arrow height compensation method, the long-wave correction values for calculate the height and lateral position of the track. The correction values corresponding height and lateral track displacement can eventually carried out in a particularly economical manner parallel to the track stabilization be replaced by the components required for the stabilization, such as static load and / or shear forces, to be changed accordingly. This is in a particularly advantageous manner in conjunction with the track position correction final track stabilization without additional work also an elimination of long-wave track position error achievable.

In the following the invention with reference to an illustrated in the drawing Embodiment described in more detail.

Show it:

  • 1 is a side view of a tamping machine for undercutting a track,
  • Fig. 2 is a side view of a track stabilizer for stabilizing the stuffed track, and
  • Fig. 3 to 5 different actual and nominal positions of the track-performing diagrams.
  • The apparent in Fig. 1 tamping machine 1 has a by rail bogies 2 on a track 3 movable machine frame 4 with a drive 5 on. Between the two rail bogies 2 is a by a drive 6 relative to the machine frame 4 längsverschiebbarer Subframe 7, with a height-adjustable Stopfaggregat 8 and a track lifting unit 9 is connected. The machine frame 4 is a machine reference system 10 for detecting arrow heights or Elevation and lateral position error of the track 3 assigned. This reference system has spaced apart in the machine longitudinal direction, on the track 3rd unrollable measuring axes 11 for scanning the track and a straightening and Leveling 12,13 on.

    The tamping machine 1 is a Meßanhänger with respect to their working direction (arrow 14) 15 with a separate reference system 16 and measuring axes 17 downstream. The at its front end via a hinge 18 with the machine frame 4 connected measuring tag 15 is with its rear End on a rail chassis 19 on track 3 supportable.

    A shown in Fig. 2 track stabilizer 20 has a rail undercarriages 21 on the track 3 supportable machine frame 22 and a traction drive 23 on. Between the two rail chassis 21 are located two stabilization units 24, by an eccentric 25 horizontal and transverse transverse to the rail longitudinal transverse forces can apply to the track 3. Parallel to this is by drives 26 a static load on the stabilizer 24 on the track 3 transferable. To detect the track geometry is a reference system 27 with measuring axes 28 provided. The track stabilizer 20 is expediently immediately after the tamping machine 1 in the same working direction (arrow 14) used. In addition to the transverse vibration forces can optionally further transverse forces by a lever system 36 with drive 37 (described in more detail by EP 0 666 371 A1) for correcting the lateral position on the track 3 be applied.

    A diagram shown in FIG. 3 shows the arrow heights on the Y-axis (these are the normal distances to a chord of a curve) of the track 3 in millimeters and on the X-axis the track the kilometers (in kilometers). One the lateral position error of the track 3 representing actual position curve 29 is through the reference system 10 of the tamping machine 1 detected immediately before the track clogging and sets off a plurality of arrowheads 30 together. The measured arrow heights 30 be with a known per se, as electronic arrow height compensation designated computer program with maximum possible consideration permissible displacement values compensated (see balancing curve 33), where required for the compensation or the curve smoothing shifts of the track 3 calculated in a likewise known factor method become.

    By the curve shown in solid lines in Fig. 4, the immediate after the suppression actually present and here as a provisional target position 31 designated position of the track 3 shown. This provisional target position 31 is passed through the measuring tag 15 immediately after the Unterstopfung Measured and shows very clearly long-wave errors. The measurement but also alternatively, for example, by a separate track measuring vehicle be performed. The data thus obtained can be, for example by radio to the conveniently the tamping machine 1 in Arbeitseinsatz immediately following track stabilizer 20 or per Floppy disk or modem. The transmitted data is stored in a computer 32 on the track stabilizer 20 read. Then be via a known per se electronic Pfeilhöhenausgleichs- and factor method the long-wave correction values for the height and the lateral position of the track 3 calculated. With the help of determined correction values 35 can the track stabilizer 20 the subsequent track stabilization in the precision process (The track is scanned at three points and given to Correction values or target arrow heights directed) perform, that is simultaneously with the track lowering to anticipate the initial set there is also a final position correction of the track. The lateral position Correction values 35 relating to the track 3 may be replaced by corresponding ones Change of the horizontal transverse forces of the stabilization units 24 and / or by appropriate admission of the Lever system 36 influencing drives 37 can be achieved. The correction values 35 (see Fig. 5) with respect to the track height attitude are about the change the static load by the drives 26 achievable, but taking into account is that the altitude correction only by lowering of the track 3 can be achieved.

    With the in Fig. 4 apparent dash-dotted curve is the final target position 34 shown after performing the electronic Pfeilhöhenausgleichsverfahrens and the factor method from the after Track sub-existing present provisional position 31 mathematically results. From the differences between the two desired positions 31 and 34 result the correction values 35. Assuming one in the direction of the arrow 14 successful operation of the track stabilizer 20 is thus in the range The kilometer 43.22 to 43.32 a correction values determined 35 corresponding increase in the lateral forces required to the left Track 3 in the determined target position 34 to relocate. Subsequently, the Transverse forces to correct the lateral position error of the track 3 to the right increase.

    The diagram shown in Fig. 5 refers to the track height position. For mathematical determination of the final target position 34 (dot-dashed Line) is to be taken into account that in all track areas a minimum reduction (x) is to be performed. By increasing the static load in the area of particular altitudes of the provisional target position 31 is the Possibility to flatten long-term altitude errors at least or Completely eliminate, finally, the track 3 in the final target position 34 lower.
