Definitions

  • the invention relates to a rail contact for an axle counter.
  • axle counters are used for the track release message.
  • An axle counter includes a rail contact and an evaluation circuit.
  • the rail contact has e.g. two transmitters and two receivers. In a cycle passage of a train this is detected inductively.
  • the rail contact is placed locally near the rail. In future implementations, it is intended to attach the rail contact directly to the rail.
  • the rail contact is fastened to the rail neck by means of two bolts.
  • the object of the invention is to provide an axle counter which can detect a defect of the rail contact as surely as possible.
  • the mounting flanges When rail contact according to the invention at least one connecting wire of an electrical component of the rail contact is connected in any way with a mounting flange.
  • the mounting flanges When tearing off the rail contact by drooping parts of a passing train, the mounting flanges usually remain attached to the rail neck, the connecting rod connected to the mounting wire, however, breaks off.
  • the electrical component is, for example, the receiving coil of the rail contact, which is also referred to as a sensor.
  • the connection of the connecting wire of the receiving coil with the mounting flange can be done in several ways.
  • a part of the connecting wire is cast in the manufacture of the mounting flange in this.
  • a part of the connecting wire is inserted, for example in the form of a loop in the shape of the mounting flange and poured over the pouring material, so that the inserted part of the connecting wire is in the cast mounting flange.
  • an additional hole is provided through the mounting flange, through which the connection wire can be guided in the cast mounting flange.
  • Another variant provides to attach an eyelet on the mounting flange through which the connecting wire can be performed.
  • the connecting wire is guided around the bolt.
  • Fig. 1 shows a side view of a rail contact according to the invention with connection to a rail.
  • the rail contact 4 has two mounting flanges 5, 6 and by way of example two coils 7, 8, which serve as a receiver or transmitter.
  • Each mounting flange 5, 6 has a hole for the passage of a bolt by means of which the rail contact 4 is connected to the rail neck 2.
  • Each bolt has a thread on one end, to which a nut is screwed. The rail contact 4 is thus secured by means of two bolts and two nuts on the rail neck 2.
  • Each coil 7, 8 are supplied with two connecting wires for producing an electrical connection between the coil and the evaluation circuit of the axle counter.
  • Each connecting wire of a coil 7, 8 is now laid by the coil for evaluation in such a way that it is first guided by a bolt through the mounting flange 5, 6 and then to the evaluation circuit. This generates a predetermined breaking point for each connection wire.
  • the mounting flange 5, 6 is made for example by casting. Before pouring the mold becomes part of the lead wire inserted into the mold, so that forms by casting a mounting flange 5, 6 with cast-lead wire. The ends of the lead wire project out of the mounting flange 5, 6 and are connected to the corresponding coil 7, 8.
  • a shock on the rail contact 4 by a passing vehicle with drooping part results in that the bolts through the rail neck still hold the mounting flanges 5, 6 of the rail contact 4 correctly on the rail, but the remaining part of the rail contact 4 including the coil 7, 8 is separated from the mounting flanges 5, 6.
  • Fig. 2 shows a top view of the rail contact Fig. 1 with the indication of the breakage of a connecting wire.
  • a predetermined breaking point for the lead wire can be generated. It can thus be used to generate a predetermined breaking point any protuberance, connectivity, nose or the like on the mounting flange 5, 6.
