    A common reference base (13) of a track position measuring system (10) consists of a single measuring chord (14) arranged centrally between the rails (4) and extending in the machine longitudinal direction. On a central track position measuring unit (12) two Meßwertge- ber (16) each contacting the measuring chord (14) for determining a longitudinal height on the one hand and for determining a Pfeilhöh on the other hand are arranged. Each track position measuring unit (12) has two laser scanners (17), each associated with a rail (4), for scanning in a y-axis normal to a rail longitudinal direction and in a z-axis extending in a vertical direction. This simplification of the track position measuring system (10) can be achieved with increased accuracy.

    专利说明:

    [01] The invention relates to a track construction machine for performing track position corrections, comprising a machine frame which can be moved by rails on rails of a track, and a track position measuring system which consists of three track tracks arranged one behind the other with respect to a machine longitudinal direction. Measuring units and one for this common reference base.
    [0002] Such a track construction machine known from AT 394 742 is designed for submerging a track. Rail track measuring units are two rail carriages connected by a machine frame and a measuring axle positioned between them, which can be rolled on the track. The machine frame is provided as a common reference base. In order to rule out a measurement distortion as a result of the deflection of the rail bogies, non-contact laser sensors are provided in the vicinity for measuring a distance between the machine frame and the rail.
    [03] It is also known from AT 382 410 to use steel tendons running as a common reference base in the machine longitudinal direction.
    The object of the present invention is now to provide a track construction machine of the type mentioned, with a simplified track position measuring system is possible.
    [05] This object is achieved with a track construction machine of the generic type by the features cited in the characterizing part of the main claim.
    [06] This combination of features allows a structurally simplified track position measuring system with high measuring accuracy both in terms of rail scanning and in terms of the common reference base.
    [07] Further advantages of the invention will become apparent from the dependent claims and the drawing description.
    [08] In the following the invention will be described in more detail with reference to an embodiment shown in the drawing. 1 shows a side view of a track-laying machine, and FIGS. 2 to 6 each show a schematic representation of a track-laying measuring system.
    A track construction machine 1 shown in FIG. 1 for carrying out track position corrections has a machine frame 3 supported on rail chassis 2 and can be moved on rails 4 of a track 5. Between the two rail bogies 2, a tamping unit 6 is arranged to Unterstopfen the track 5. With respect to a working direction 7, immediately before the tamping unit 6, a track lifting and rich-tagging unit 8 as well as said tamping unit 6 are connected to a satellite frame 9 which is displaceable relative to the machine frame 3 in a machine longitudinal direction 11.
    For the determination of track position errors, a track position measuring system 10 is provided, which is arranged from three with respect to the machine longitudinal direction 11 arranged behind one another, respectively the position of the rail 4 detecting track position measurement units 12 and a common reference base for this 13 , This consists of a single, centrally disposed between the rails 4 and extending in the machine longitudinal direction 11 measuring chord 14th
    [11] Each track position measuring unit 12 is assigned an inclinometer 15 for detecting a transverse height of the track 5. The with respect to the machine longitudinal direction 11 central track position measuring unit 12 is attached directly to the track lifting straightening unit 8, while the two end track position measuring units 12 are arranged together with the associated inclinometer 15 each on the rail chassis 2. The inclinometer 15 associated with the central track position measuring unit 12 is positioned on the satellite frame 9 (see Fig. 2).
    On the central track position measuring unit 12 are two each the measuring chord 14 contacting transducer 16 for determining a longitudinal height (which is the difference between Soil- and actual position of the track in the verti-kaler direction) on the one hand and for determining an arrow ( corresponds to the difference between the solid and actual position of the track in the horizontal direction) on the other hand arranged.
    Each of the three track-laying measuring units 12 has two laser scanners 17, each associated with a rail 4, for scanning in a horizontal y-axis normal to a rail longitudinal direction and in a z-axis running in the vertical direction (see FIG ).
    As schematically illustrated in FIGS. 2 and 3, each height-adjusting position of the track lifting straightening unit 8 provided and hinged to the satellite frame 9 lifting drive 18 is a transducer 19 for the detection of a height caused by raising the track 5 height -rung assigned.
    The schematic representation of FIG. 4 refers to a well-te variant of a track construction or tamping machine 1. In this, the tamping units and track lifting straightening units not shown here are fastened directly to the machine frame 3 for a step-by-step approach , In this variant, the two outer track position measuring units 12 are respectively arranged in the vicinity of the rail chassis 2 directly on the machine frame 3. The central track position measuring unit 12 is also connected to the machine frame 3 together with the associated inclinometer 15 in the area of the track lifting straightening unit.
    [16] In FIG. 5, the laser scanner 17 which is displaceable relative to the machine frame 3 is shown enlarged. This has a in a vehicle transverse direction reciprocating mirror 20 for deflecting a laser beam 21. As a result, in each case a cross-sectional profile of
    Track 4 in conjunction with a plurality of successive laser beams 21 (see Fig. 6) scanned.
    [17] With this scanning movement in the horizontal y-axis, which is normal to the longitudinal direction of the rail, and the z-axis running in the vertical direction, both a rail upper edge (SOK) for the vertical position and a rail inner edge (SIK) for a Arrow height are registered (see Fig. 6). This is composed of a transverse displacement path q (resulting from the transverse displacement relative to the machine frame 3) and a distance a defined by the transverse movement of the mirror 20. The rail top edge (SOK) results from the shortest vertical distance h with respect to the rail 4.
