Definitions

  • the present invention relates to a security barrier, in particular a level crossing or parking barrier, comprising at least one heald provided with at least one element conductor of electricity connected to a device allowing to detect a variation or an interruption of the electrical continuity of the conductive element.
  • Such barriers are installed in multiple crossing points, especially on rail networks and road, or on parking areas.
  • the present invention proposes to remedy this disadvantage and, to do this, the barrier it concerns is characterized in that the conductive element consists by a conductive loop comprising several strands conductors carried by a fibrous support.
  • the detection device can therefore transmit to a monitoring station an alert signal as soon as a change or an interruption in the electrical continuity of the loop conductive occurs, which triggers a rapid rescue intervention for repair.
  • the loop conductive In the event of an accidental break in the arm, the loop conductive virtually breaks due to its structure particular, which allows the detection device to issue an alert signal without fail.
  • the conductive strands are weak unit length, which makes it possible to obtain a conductor of semiconductor type.
  • the conductive strands are braided.
  • the conductive loop is housed in the thickness of the arm and advantageously, when the heddle consists of a composite material, the conductive loop is then embedded in the interior of said composite material.
  • the elongation at rupture of the conductive loop has an elastic limit close to that of the elongation at break of the arm.
  • the rupture of the arm and the conductive loop are concomitant, whereas in the general case the loop conductor breaks before the stringer.
  • the conductive loop is arranged in parallel to the longitudinal axis of the boom and preferably symmetrically with respect to this axis.
  • the conductive loop follows the axis of the boom and that it is arranged on the side and on the other side of this axis, the rupture of the barrier being able occur on either side of the boom.
  • the heald when the heald is connected to a barrier base by means of a fixing heel and has a break zone located at a certain distance of the heel, the conductive loop extends from the fixing heel at least up to the break zone.
  • the length of the conductive loop is thus chosen in function of that of the beam which comprises by experience at minus a break zone near the fixing heel.
  • the device making it possible to detect a variation or an interruption in continuity electric conductive loop is placed inside of the barrier base, and preferably the conductive loop is connected to the device allowing to detect a variation or an interruption in the electrical continuity of the loop by means of a connecting conductor or a conductor flexible connection.
  • Figure 1 shows a crossing barrier 1 comprising a base 2 and a rail 3 fixed by a few bolts on a fixing heel 4 connected to the base.
  • the boom is made of a composite material, in the thickness of which a conductive loop 5 extends symmetrically with respect to the longitudinal axis of the heddle.
  • the conductive loop consists of a conductor section 1 to 2 mm, which consists of a succession of strands non-continuous about 10-20 microns in diameter and preferably stainless steel, these strands being in contact the ones with the others.
  • the strands are braided and carried by a fibrous support.
  • the resistance of the conductor is between 500 and 3000 Ohms.
  • the elongation at break of the conductive loop has a elastic limit equal to that of elongation at break smooth.
  • Each end of the conductive loop is connected to the ends of a flexible connecting conductor 6 housed in the fixing heel.
  • the flexible connection conductor is connected to each of its other ends to a known device 7 making it possible to detect a variation or an interruption in continuity electric of said loop.
  • the loop conductive extends from the heel of attachment to a little beyond the usual break zone of the beam, zone located at a predetermined distance d from the fixing heel.
  • the beam is 4.85 m long, the distance d is around 1 m and the conductive loop extends over 1.60 m from the heel of attachment, ie beyond of the break zone, but not over the entire length of the smooth.
  • the device according to the invention operates in the manner next, as it also appears figure 2.
  • the device for detecting a variation or a interruption in the electrical continuity of the loop conductor detects a variation or an interruption in the electrical continuity and is then able, by means known, to issue an alert signal or to transmit the signal detected.
  • a maintenance intervention can then be immediately triggered, to replace the boom.
