Steering mirror secured as a radiation network over the danger area, its barrier structures

Release of rail traffic above (Jen level crossing to be closed, as shown in the drawing is shown.

The resulting danger space between the closed barriers 4 and 5 is monitored in the illustrated embodiment by two sensor rods 6 and 7, which are arranged parallel to the barrier beams 4 and 5 and are each mounted on a carrier or 9. The feeler rods 6 and 7 are together with the barrier booms 4 a and 5 "can be pivoted in a vertical plane, to release street 3 when barriers 4 and S are open.

After closing the barriers 4 and 5, the sensor rods 6 and 7 are pivoted in a horizontal position about a vertical axis by 90 ° clockwise. At the end of this pivoting movement they actuate a limit switch 6 b or 7 b, which indicates by Konta'ktgabe that the sensor rods 6 and 7 have carried out their full pivoting movement. The signal sent by the end switches 6 b and 7 b causes the sensor rods 6 and 7 to pivot back into the initial position shown, in which the sensor rods 6 and 7 interact with a further end switch 6 a and la . These limit switches 6 a and la signal a proper return of the sensor rods 6 and 7 and thus the absence of obstacles in the danger area. The limit switches 6a and la and possibly 6b and Ib are switched on in the circuits of signals 10 and 11 for the train journey, so that rail traffic is only able to pass the level crossing when the sensor rods 6 and 7 are touched by the limit switches 6 α and 6 b or 7 α and 7 b have checked the hazardous area for the presence of obstacles and have properly returned to their end position.

The sensor rods 6 and 7 are arranged at a low level above the road 3. You can paint over the danger zone either one after the other or at the same time, for which purpose it is necessary in the latter case that they are slightly offset from one another in height. If the feeler rods 6 and 7 hit an obstacle, they stop so that the signal from the corresponding limit switch fails to appear. In this case, the train journey remains blocked because signals 10 and 11 do not receive a release pulse from the respective limit switch.
