    A tamping machine for submerging a track has a lifting and straightening unit (13) connected to lifting and straightening drives (14, 15) for shifting the track to a desired position. On this a vibrating vibration exciter (24) is arranged. This makes it possible to stop a section of track in a first working pass and to lower it in a controlled manner in an immediately following second pass under permanent load and vibration effects. After that, the track can again be traveled completely unhindered at normal speed.

    专利说明:

    The invention relates to a tamping machine for submerging a track or a method for performing a position correction of a track according to the cited in the preamble of claim 1 and 6 features.
    Tamping machines for submerging a track are widely known and are essentially equipped with a tamping unit, a lifting-straightening unit and a track measuring system. The track is lifted with the help of the lifting straightening unit according to the position errors indicated by the track measuring system in a desired position and fixed in this by the use of Stopfaggregates.
    In order to eliminate the initial setbacks of the track which often occur after a clogging, this is converted into horizontal transverse vibrations by the use of a so-called dynamic track stabilizer (for example according to W02008 / 009314) under permanent load of a high load. This leads to a controlled track reduction and a corresponding compression of the sleeper bearings. Thus, the unavoidable after a Unterstopfung subsidence of the track are deliberately anticipated.
    The object of the present invention is now to provide a stuffing machine or a method of the type mentioned, with the or an extended range of application is made possible.
    This object is achieved by the features cited in the characterizing part of claim 1 and 6, respectively.
    With such a combination of features, the field of application of a tamping machine can be extended in a particularly advantageous manner insofar as can be selected with a minimum of additional design effort as required between a track position correction by means of underfilling or a track position correction by targeted track lowering. These advantages can be particularly in short, limited by switches track sections, z. B. in a station area, be optimally utilized, since in conjunction with a relatively short track barrier already a complete position correction is feasible and thus the track section can be fully released for train traffic.
    Further advantages of the invention will become apparent from the dependent claims and the drawing description.
    In the following the invention will be described in more detail with reference to embodiments shown in the drawing. 2 and 3 show an enlarged side view of the lifting and straightening unit or its view in a machine longitudinal direction, and FIG. 4 shows a simplified representation of a further embodiment of the tamping machine.
    A tamping machine 1 shown in FIG. 1 has a machine frame 4 which can be moved by rail carriages 2 on a track 3. to
    Detection of track position errors, a measuring axes 5 and 6 measuring track measuring track system 7 is provided. A tamping unit 9, which can be adjusted in height by a drive 8, is equipped with stuffing tongs 10 which can be submerged in gravel of the track 3 for underfilling purposes.
    With respect to a working direction 11 of the tamping machine 1 is located directly in front of the tamping unit 9 by means of flange rollers 12 on the track 3 unrollable lifting-leveling unit 13 with an aggregate frame 19. This is about lifting and straightening drives 14, 15 (s. Fig. 2, 3 ) are connected to the machine frame 4 to shift the track 3 in a predetermined by the track measuring system 7 target position. In order to produce a frictional connection with the track 3, pivotable lifting rollers 17 and a height-adjustable lifting hook 18 are connected to the unit frame 19 by a drive 16 (see FIGS. This is articulated by Anlenkstangen 20 on the machine frame 4 and by means of a drive 21 relative to the machine frame 4 in a machine longitudinal direction 22 displaced.
    As can be seen in particular in FIGS. 2 and 3, the lifting / straightening unit 13 is connected to a vibration exciter 24 which can be set into vibration by a hydraulic drive 23 and which has two imbalance masses 25 that can be offset in rotation by the drive 23 and a gear 26. The wheel flange rollers 12 are formed by drives 27 in a horizontal, transversely to the machine longitudinal direction 22 extending direction relative to the unit frame 19 slidably (see Fig. 3).
    To perform a position correction, a section of the track 3 is raised by the use of the lifting and straightening unit 13 in the predetermined by the track measuring system 7 target position in a first cycle and (in the case of tamping machine 1 shown in FIG. 1) in the context of a discontinuous Arbeitsvorfahrt of Threshold to threshold supported. For lifting the track 3, either the lifting rollers 17 or the lifting hooks 18 are selectively brought into engagement with rails 28.
    In anticipation of initial settlement of the track 3, the just-cushioned section is lowered in a controlled manner in a subsequent second pass involving the track measuring system 7. For this purpose, under the plant of lifting rollers 17 to the rails 28 frictionally detected track 3 in a continuous work approach under the action of the actuators 14 (which are applied here in comparison to the first working passage in the opposite direction) charged with a vertical load. At the same time takes place under the action of the actuators 23 activation of the vibration exciter 24 with a resulting rotation of the imbalance masses 25, whereby the track 3 is permanently displaced in horizontal, normal to the machine longitudinal direction 22 oscillations.
    With this second work passage, which concludes the track processing, a uniform structure of the ballast compaction and thus an advantageous increase in the transverse displacement resistance is achieved. As a result, the track can be traveled at an unrestricted speed immediately while avoiding disadvantageous slow-moving traffic.
    As an alternative to the rotating imbalance mass having vibration exciter 24, the vibrations could also be generated by a hydraulic vibration drive.
    According to the embodiment shown in FIG. 4, the tamping machine 1 has a satellite frame 30, which is displaceable by a drive 31 relative to the machine frame 4 in the machine longitudinal direction 22. Stopf- and lifting straightening unit 9, 13 are connected to the satellite frame 30. A required for the track position correction track measuring system is not shown here for the sake of simplicity.
    In a first pass for processing a track section, the tamping machine 1 is moved continuously, while parallel to the satellite frame 30 is moved together with the stuffing and lifting-straightening unit 9, 13 discontinuously from one to the next Stopfstelle. In an immediately subsequent second pass, the satellite frame 30 is used together with the machine frame 4 in a continuous work approach. In this case, by means of the vibration exciter 24 positioned on the lifting and straightening unit 13 -as is already described with reference to FIGS. 1 to 3-a permanent vibration and ballast transmission to the track 3 takes place.
