Definitions

  • the invention relates to a machine with a cyclically usable working device for processing a track having rails and tracks and with a non-contact scanning device for detecting a threshold position in conjunction with a path measuring unit for detecting a path traveled by the machine on the track and with a control unit for centering the Operating device in response to the sensed threshold position and a method for non-contact scanning of thresholds.
  • an electron-optical control device in the form of a television camera, by which the operator can make an individual adjustment of the tamping unit to the position of the thresholds.
  • US 5,671,679A discloses the use of various types of sensors for non-contact sensing of the location of a threshold plate or similar target.
  • JP 322707/94 A it is also known to determine the difference between the threshold and ballast surface on the basis of an image processing device formed by a light slot and a camera and to control the lowering of tamping units of a tamping machine accordingly.
  • the object of the present invention is now to provide a generic machine and a method by which or the improved detection of a threshold position is guaranteed.
  • this object is achieved with a machine of the generic type, characterized in that the scanning device is designed as a distance meter for non-contact detection of vertical Distanzmeß exchange between the scanning on the one hand and sleepers or gravel of the track on the other hand, and that connected to the distance meter control unit for a continuous and successive subdivision of the path-dependent measuring path is formed in each case in a threshold detection section X comprising only slightly different distance measured values and an adjoining ballast detection section Y characterized by a sequence of abruptly changed distance measuring values.
  • a machine 1 illustrated in FIG. 1 has a machine frame 3 supported on rail carriages 2 and can be moved by a travel drive 4 on a track 7 formed from sleepers 5 and rails 6.
  • a cyclically usable working device 8 is arranged in the form of a tamping unit 9. This is a track lifting unit 10 and a reference system 11 assigned.
  • a working direction shown by an arrow 12 in front of the working device 8 are located in the cross machine direction two opposing scanning 13 for detecting the threshold position in the track. 7
  • a travelable on the rail 6 Wegmeßtechnik 14 is provided. This is just like the scanner 13 with a control unit 15 in connection.
  • the scanning device 13 is designed as a distance meter 16 for a non-contact measurement of the vertical distance to the underlying threshold 5 or to gravel 17.
  • a measured curve 18 detected as a function of the distance s traveled by the machine 1 is composed of a plurality of distance measured values d.
  • the measuring curve 18 is composed in an alternating sequence of a threshold detection section X having only slightly different distance measured values d and a ballast detection section Y which is composed of a large number of distantly measured distance values d.
  • the beginning and the end of the threshold detection section X can be detected relatively easily by assigning a jump A or B, respectively.
  • a centering point Z x is determined for the time-shifted centering of the tamping unit 9 above the corresponding threshold 5.
  • the distance measured values d lying within the two discontinuities A, B are within a minimum bandwidth m with their respective maximum values.
  • the distance measuring values d defining the ballast detection section Y, with their maximum values, are clearly outside the minimum bandwidth m.
  • two distancers 16 spaced apart in the cross-machine direction are provided in order to scan the threshold position along two lines of measurement 21 running in the longitudinal direction of the track in the context of a work precedence of the machine 1.
  • the two following tamping units 9, not shown here can be centered independently of each other optimally above the respective threshold section for initiating the tamping process.
  • the path-dependent trace 18 formed of a plurality of distance readings is divided into successive threshold detection sections X and ballast detection sections Y, for example, those lying only within a minimum bandwidth m Distance measurements d are filtered out.
  • limit values for defining the minimum bandwidth m and a minimum and maximum width of thresholds 5 possibly occurring in the track 7 for defining a threshold acceptance range SA can be input.
  • a plausibility check of the previously determined threshold detection section X is carried out as to whether the threshold width defined by the two discontinuities A, B lies within the limit values stored in the input unit 22. If this check is negative, the activation of an audible and / or visual warning device 24 to alert an operator to the unclear situation occurs.
  • the centering point Z x is determined by halving the path distance between the discontinuities A, B, stored and sent away for an automatic foremost stop of the machine 1, in order finally to center the tamping units 9 above the respective threshold 5.
