Definitions

  • the invention relates to a method and 1 a device for diagnosis and condition monitoring of a wear and functional state of a switch and / or intersection and / or a crossroads and / or rail joints and / or track inhomogeneities of a railroad track, which consists of several rails.
  • intersections and intersections divide several tracks of rail traffic into a track and connect them together or, at an intersection, pass a track through another track.
  • An unobstructed and almost track-stable running of a wheel of a rail vehicle, which rolls over a switch, intersection or intersection, ensures a so-called heart, which is located at a cutting point of the intersecting tracks.
  • a distinction is made between rigid and movable frogs.
  • a planned interruption of a running edge at the point of intersection is present, the so-called center piece gap. This heart gap causes the wheel to roll over the diverter, intersection or crossover over a groove as it rolls over, causing shock-like shocks and stresses on both the wheel and the rigid centerpiece.
  • DE 195 80 680 T2 discloses a mobile tracking unit for detecting defect states in rail vehicles and rail tracks.
  • the mobile tracking unit comprises a rotation measuring unit for determining the rotational speed of a wheel set, a motion sensor, in particular in the form of an acceleration pickup, a data processor, a navigation set and a transmitter for transmitting determined data to an evaluation center.
  • the disadvantage here is that a special mobile tracking unit is required for detecting defect states, i. a special vehicle that needs to track a rail vehicle.
  • Claim 1 specifies a method for the diagnosis and condition monitoring of a switch and / or intersection and / or a crossroads and of rail joints and track inhomogeneities of a railroad track.
  • intersection or crossing points and rail joints or Gleis ⁇ inhomogeneities on at least one component of the rail vehicle vibration accelerations in at least one spatial direction measured and stored at the component of the rail vehicle by the crossing of the rail vehicle on the switch, crossing or crossing soft as well as rail joints and track inhomogeneities are generated.
  • vibration accelerations during crossings of a rail vehicle are thus measured and assessed in a location-specific manner.
  • Rail joint and track inhomogeneities as rising Schwingungs ⁇ accelerations are caused in particular by increasing deviations of their geometry from their nominal shape and their location from their desired position.
  • rolling over a rail wheel over the frog gap in rigid frogs always occurs with increasing wear.
  • high vibration accelerations high energy inputs into individual components of the switch, intersection or intersection and the rail joint and track inhomogeneities promote the progression of wear and accelerate.
  • the speed of the rail vehicle is additionally measured and stored, and the direction of travel and the location of the switch, intersection or intersection and the rail joint and track inhomogeneities are determined and stored.
  • Signaling preprocessing of the measuring signals on board the vehicle is advantageously carried out subsequently, so that only extracted data such as direction of travel, wheel set accelerations, driving speed, spatial position of the train must be transmitted via interfaces of the vehicle.
  • predetermined limit values of the oscillation acceleration are exceeded, a subsequent further measurement of a state of components of the points, crossing or crossroads is brought about, in particular in accordance with the specifications DS 820 06 05 B5 or BN 824.9005.
  • a measurement of the vibration acceleration by means of acceleration sensors is carried out according to claim 2 in the vicinity of the contact point of the wheel and rails, in particular according to claim 3 on a Radsatzlagerdeckel, or according to claim 4 as far as possible at the wheel-rail contact point, in particular a particularly selected for measuring wheelset attached.
  • a satellite-based position-indicating device in particular GPS, DGPS or Gallileo is advantageously used to determine the position of the train. This advantageously also a position indication on routes is possible that do not have train control systems that tell the rail vehicle its position on the track.
  • the rail joint or the track inhomogeneity determined at least one acceleration sensor on at least one component of the rail vehicle, a vibration acceleration, the rail vehicle by crossing over the heart or creates the discontinuity.
  • the acceleration sensors determine the vibration acceleration either only in one spatial direction or particularly advantageously in several, in particular all three, mutually perpendicular spatial directions.
  • special acceleration sensors can be used to determine rotational and / or pitching movements on at least one component of the rail vehicle.
  • a local assignment of the determined vibration accelerations to the corresponding measured turnout, crossing or intersection, rail joint and track inhomogeneity can take place.
  • the advantage in this case is that, when irregularities occur or when characteristic, predetermined limit values of the vibration acceleration are exceeded, maintenance personnel are guided precisely to the corresponding conspicuous switch, intersection or intersection, rail impact and track inhomogeneity.
  • a position indication of the rail vehicle present in the rail vehicle is used in conjunction with the position of the accelerometer within the rail vehicle.
  • This position indication of the rail vehicle takes place in particular via train control systems of the traveled route, which inform the rail vehicle of its position on the track, in particular a felicitnzugbeeinpoundung (LZB) or a European Train Control System (ETCS), or via a satellite-based position indicating device of claim 5.
  • train control systems of the traveled route which inform the rail vehicle of its position on the track, in particular a felicitnzugbeeinpoundung (LZB) or a European Train Control System (ETCS), or via a satellite-based position indicating device of claim 5.

  • the speed measuring device and the locating device are combined in a single device, so that a separate speed measuring device is unnecessary.
  • a data acquisition system prepares the measuring signals of the acceleration sensors, the speed measuring device and the locating device, stores them in particular electronically or magnetically and evaluates them accordingly. Furthermore, the data acquisition system checks whether characteristic, specified limit values are exceeded.
