Definitions

  • the invention relates to a monitoring device for monitoring a temporary rail connection of two rail sections of a rail.
  • the invention further relates to a rail connection system for producing and monitoring a temporary rail connection of two rail sections of a rail.
  • a rail connection system for establishing and monitoring a temporary rail connection is known.
  • rail straps are used to create a temporary connection between the successive rail sections so that the track can continue to be used at reduced travel speeds.
  • the rail straps are firmly attached to both sides of the rail sections using clamps.
  • a safety device is provided which includes two sensor tabs. A first sensor tab is attached by a clip to a first side next to one of the rail tabs. The sensor tab includes a first distance sensor that determines a distance between the first sensor tab and the adjacent rail tab. Accordingly, the second sensor tab is attached to a second side next to the rail tab by a clip.
  • the second Rail tab includes a second distance sensor that determines a distance between the second sensor tab and the adjacent rail tab. If the measured distances change but their sum remains unchanged, it is recognized that the position of the rail strap has changed and the gap between the rail sections has remained constant. If, on the other hand, the sum of the measured distances changes, an increase in the gap between the rail sections is detected.
  • the emergency tab connector includes tabs that are attached to two successive rails by means of clamping devices for temporary connection.
  • the safety system is attached to one of the rails to the side of the emergency tab connector.
  • the security system includes a distance measuring device for measuring a distance between the security system and one of the tabs.
  • a device for detecting rail movements comprises a transmitter and a receiver which are attached to a rail at a distance from one another.
  • the orientation of the transmitter changes relative to the receiver, which changes the point of impact of a measuring beam from the transmitter on the receiver.
  • the change in the point of impact is proportional to a change in angle and therefore proportional to a change in force between a rest position and a loaded state of the rail.
  • the invention is based on the object of creating a simple monitoring device which enables reliable monitoring of a temporary rail connection of two rail sections of a rail.
  • the first fastening element is attached to the first rail section, whereas the second fastening element is attached to the second rail section.

  • the first distance between the fastening elements is measured using the first distance sensor.
  • the second distance sensor is used to measure the second distance between the first fastening element and the first clamping device for the at least one rail tab.
  • the measurement of the first distance and the second distance is carried out in particular repeatedly and each in one common time window, preferably simultaneously and/or periodically. Based on the first distance and the second distance, on the one hand, an undesirable displacement of the first fastening element and, on the other hand, an undesirable displacement of the first clamping device are recognized and differentiated. If both the first distance and the second distance change, the first fastening element has shifted in an undesirable manner. If the second distance changes and the first distance remains the same, the first clamping device has undesirably shifted.

If both the first distance and the third distance change, an undesirable displacement of the second fastening element is detected.
  • the third distance changes and the first distance remains the same, an undesirable displacement of the second clamping device is detected. If the first distance increases and the second distance and the third distance remain the same, the first fastening element and the second fastening element have not shifted and the increase in the first distance is reliably recognized as an increase in the gap.

  • the fastening elements are closed by the connecting element connected to one component, which enables easier handling and assembly or disassembly of the fastening elements.
  • a monitoring device ensures reliable monitoring of the temporary rail connection in a simple manner.
  • the fact that the connecting element can be extended in the longitudinal direction of the rail ensures a reliable measurement of the first distance.
