  • the invention also relates to a method for monitoring a detachable connection of a switch or crossing component in the form of a frog or a tongue rail device, wherein by means of the detachable connection a replaceable component in the form of a frog insert or a tongue rail is fastened to a base component in the form of a frog block or a tongue rail adapter and wherein by means of a sensor a signal for checking the quality, in particular the force transmission or the form fit, of the detachable connection is detected, which signal is generated when a rail vehicle passes over the switch or crossing component and is representative of the quality of the detachable connection,
  • a remote monitoring system for a railway network for monitoring operating parameters of at least one switch system of the railway network is known.
  • Each switch system is designed to include a set of sensors, each adapted to measure a property value representative of a particular property.
  • the sensors are each connected to a data acquisition unit that stores an algorithm for managing the acquired measurement data.
  • means are provided for comparing the measured data with at least one threshold value which is representative of the limit value for a corresponding operating parameter.
  • the known arrangement includes, for example, a replaceable component in the form of a check rail, which is connected to a base component in the form of a track via a detachable connection.
  • a sensor is provided to monitor the clamping of the check rail to the track, which is achieved by the detachable connection.
  • This sensor is located in the check rail, which means that when the check rail is replaced, the sensor must also be replaced or dismantled. This involves increased effort.
  • the method also provides for monitoring the quality of the clamping of the check rail using measurement signals supplied by an acceleration sensor which detects the shocks generated by a wheel on the check rail.
  • the DE 200 16 674 U1 concerns a system for measuring the approach to the frog point of a switch.
  • the system is characterized by a structure-borne noise sensor that is inserted into the frog of the switch or a component connected to this frog. If the switch is approached at an acute angle and the flange of a wheel hits the frog point due to misalignment or wear on one of the check rails, a violent shock occurs, with the resulting structure-borne noise pulse being transmitted through the base plate of the frog to the wing rail firmly screwed to it and thus registered by the structure-borne noise sensor.
  • the sensor is located laterally in a wing rail and would be inaccessible on tracks that are typically covered in trams.
  • the DE 10 2004 014 282 B4 relates to a method for diagnosis and condition monitoring in the overrun area of a switch and/or a crossing and/or a crossing switch of a railway line.
  • a measurement of the acceleration of the switch or the crossing point is carried out at the rigid frog or at the crossing point at at least one location on the frog or crossing point in at least one spatial direction, which acceleration is generated by the train passing over the switch or the crossing point.
  • a detachable connection is not monitored.

  • the senor In order to enable a simple replacement of a defective sensor or a component to be replaced, i.e. without destroying a track covering or without dismantling the intact sensor from the component to be replaced, the sensor is arranged in the base component and firmly connected to it.
  • both the sensor and the supply line remain unaffected by the change of component, as the sensor is not in contact with the replaceable component.
  • the senor is preferably designed as an acceleration sensor or structure-borne sound sensor.
  • the senor is arranged in the base component for transmitting accelerations and mechanical vibrations such that when a rail vehicle passes over it, in particular over an insufficiently fastened replaceable component, it detects at least one impact exerted by the insufficiently fastened replaceable component on the at least one detachable connection and/or the base component as an acceleration and/or mechanical vibration.
  • the switch or crossing component is a frog

  • a clamping washer and a first sealing ring are arranged between a head of the clamping screw and an upper side of the clamping wedge.
  • a second sealing ring can preferably be arranged between an underside of the clamping wedge and the base component.
  • the invention relates to a method for monitoring a detachable connection of a switch or crossing component in the form of a frog or a tongue rail device, wherein by means of the detachable connection a replaceable component in the form of a frog insert or a tongue rail is fastened to a base component in the form of a frog block or a tongue rail adapter, and wherein by means of a sensor a signal for checking the quality, in particular the power transmission and/or the positive connection, of the detachable connection is detected, which signal is generated when a rail vehicle drives over the switch or crossing component, in particular the replaceable component, and is representative of the quality of the detachable connection.
  • the signal is generated when the rail vehicle passes over the replaceable component by at least one impact exerted by the replaceable component on the detachable connection and/or on the base component and is detected by the sensor arranged in the base component.
  • the signals generated when the rail vehicle passes over due to a relative movement or a displacement of the replaceable component and/or due to a replaceable component displaced from the optimal position with respect to the detachable connection and/or the base component are evaluated.
  • an acceleration sensor or a structure-borne noise sensor is preferably used as the sensor.
