Definitions

  • the invention relates to a track construction machine with a machine frame which can be moved on a track by rail carriages and a track scanning unit that is adjustably connected to it and can be moved by flange wheels on the track, and to a method for detecting a track position.
  • EP 1 028 325 A2 describes a method for measuring a track with the aid of two measuring vehicles which can be moved independently of one another on the track and which are set up at the end points of a track section to be measured.
  • the object of the present invention is now to provide a machine or a method of the generic type, with which the position of a track is quickly and reliably accurately detected.
  • this object is achieved with a machine of the type mentioned above in that the machine frame is connected to an antenna having an antenna center having satellite receiver, and that a measuring device for detecting the relative position of the antenna center with respect to the track scanning unit with respect to the parameters: track bank , Transverse displacement perpendicular to the machine longitudinal direction and vertical distance and a computing unit for computational displacement of the antenna center with respect to a reference point of the track scanning unit is provided.
  • a track construction machine 1 shown in FIGS. 1 and 2 has a machine frame 2 which is supported on track 4 by rail carriages 3 and provided with driving or work cabins 5 and with a drive unit 6.
  • the machine 1 is equipped with a mobile independently of this on the track 4 satellite vehicle 7 and formed by means of which for measuring an actual position of the track 4 in a direction shown by an arrow 8 working direction. (This is already known, for example, from EP 1 028 325 A2, which is why it will not be discussed further here.)
  • This track scanning unit 9 is essentially designed as a track-movable measuring axis 11, which is pivotally connected to the machine frame 2 and connected to this by means of (not shown for reasons of space) drives height adjustable by means of which the measuring axis 11 at the beginning of operation of the machine 1 on the rails 12 of the track 4 is lowered or Schemeins.
  • a satellite receiver 13 is mounted on the machine frame 2 having an antenna 14 with an antenna center 15 and for receiving extraterrestrial position (or GPS) signals transmitted via satellites.
  • a laser receiver 28 is used in conjunction with a laser transmitter 29 for generating a measuring line 30th
  • a measuring device 16 is further provided, which is provided for detecting the relative position of the antenna center 15 with respect to the track scanning unit 9.
  • This measuring device 16 is formed as - connected to the machine frame 2 on the underside 27 - laser scanner 17 with a running in the cross-machine direction scanning plane 18 having an origin 19.
  • the origin 19 forms an optical center 24 of the measuring device 16 which is positioned above the track scanning unit 9 with respect to the machine longitudinal direction.
  • On the measuring axis 11 of the scanning unit 9 located vertically underneath is a for scanning arranged by the laser scanner 17 scanning target 20, which is formed as centrally located between the flange rollers 10 and extending in the cross-machine direction ruler 21. This has a center also between the flange rollers 10 arranged reference point 22, which has the shape of a protruding from the ruler 21 in the vertical direction pin 23.
  • the detection of the position of the antenna center 15 relative to the track scanning unit 9 takes place with reference to the following parameters: track bank ⁇ , transverse displacement d normal to the machine longitudinal direction and vertical distance a.
  • track bank ⁇ transverse displacement d normal to the machine longitudinal direction and vertical distance a.
  • the position of the antenna center 15 of the satellite receiver 13 located on the machine frame 2 of the machine 1 relative to the reference point 22 of the track scanning unit 9 which can be rolled onto the track 4 and connected to the machine 1 is determined, by means of which the coordinate position of the antenna center 15 is determined the position signals (GPS signals) - automatically the absolute track position coordinates are registered in the track scanning unit 9.
  • Fig. 3 shows the measurement of the inclination of the machine frame 2 relative to the measuring axis 11.
  • the machine frame 2 due to the suspension of the rail bogies 3 have a different bank than the measuring axis 11, which corresponds to the track bank ⁇ .
  • This different bank is determined by the laser scanner 17 by an XY coordinate system is spanned, which has its zero point at the origin 19 of the scanning plane 18 of the laser scanner 17.
  • the coordinates x1, y1 and x2, y2 of the two in the cross-machine direction outer, striking the ruler 21st Laser beams or their target points can now be calculated in the coordinate system. From this, the frame inclination ⁇ is determined (also mathematically).
  • this angle a only indicates the relative angle between the machine frame 2 and the measuring axis 11, it is necessary to determine the absolute frame inclination (relative to the horizontal).
  • the bank angle ⁇ corresponding to the bank of the measuring axis 11 is measured by a mounted on this inclinometer 26. From this value ⁇ , the frame pitch ⁇ is now subtracted to obtain the absolute frame pitch.
  • the laser scanner 17, whose angular resolution is about 0.05 °, provides for each step a measure of the angle and the distance to the scanned ruler 21.
  • the reference point 22 forming, projecting in the center of the ruler 21 pin 23 through the Laserscanner 17 clearly identified or its horizontal and vertical position can be determined relative to the origin 19.
  • both the horizontal and the vertical distance between the machine frame 2 and measuring axis 11 can be determined from this.
  • that scan is selected which has the minimum distance in the center region.
  • This scan is characterized by the distance a and the angle ⁇ in an XY coordinate system in which the machine frame forms the X-axis and the zero point lies in the origin 19 of the laser scanner 17.
  • the reference point 22 is now determined in terms of coordinates based on these values a and ö.
  • the whole coordinate system Since the said coordinate system is initially rotated by the frame inclination from the horizontal, the whole coordinate system still has to be rotated around the frame inclination to the horizontal in order to calculate the vertical height and the horizontal distance to the zero point.
  • the vertical distance and the horizontal distance between the GPS antenna 14 and the point of contact of the track scanning unit 9 with the rail 12 are then computationally determined.
