Definitions

  • the present invention relates to network switches railway, and more particularly relates to an elastic fixing device of a rail against the needle of switches or the like.
  • Devices of this type are notably known, for example DE-A-21 53 534 and DE-A-32 30 612.
  • Railway network switches are usually constituted, for each row of rails, by a fixed counter-needle rail with which cooperates a movable needle rail moving transversely to the axis of the track, and can be, at will, applied or separated from the adjacent needle rail.
  • a switch is said to be "high needle” in the case where the needle rail has the same height as the needle rail, and “low needle” in the case where the needle rail is less tall than the needle rail.
  • the needle rail rests in its movable part on sliding bearings.
  • a special sliding bearing which has a recess allowing the insertion of an elastic clip substantially U-shaped, the head of this fastener resting on the inner shoe of the needle rail.
  • Support effort on the skate which is of the order of 1200daN, is obtained by tensioning this fastener by arrangement of the two ends of its branches in two raised housing provided for this purpose and located at the end of the bearing.
  • the elastic fastener is a sensitive part of the device and must therefore be positioned precisely and without undergo no damage during its installation, in order to avoid deterioration premature, which would lead to an increased risk of rupture putting security seriously at stake.
  • the assembly is carried out, in principle, in five steps, namely the insertion of the fastener in the recess, the setting in place of a branch in the intermediate position, its displacement up to final position, followed by placing the other leg in position intermediate and its displacement to the final position.
  • the object of the present invention is to overcome these drawbacks by proposing an elastic fixing device of a rail against the needle of switches or the like allowing positioning precise of the latter and avoiding any risk of rapid wear.
  • the elastic fastening device rail of track in particular of a fixed counter-needle rail of switches cooperating with a movable needle rail capable of moving transversely to the track, these rails resting on a sliding pad, the needle rail being held on the bearing, on the one hand, on the outside of the track by a fixing means and, on the other hand, on the inside of the track by an elastic fastener substantially in U-shaped, arranged in a recess in the bearing and the ends of the branches penetrate, in the tensioning position of the elastic fastener by by means of a stop ensuring the effort of plating the counter-needle rail on the bearing, in raised housings provided for this purpose in said bearing, is characterized in that the bearing further comprises, at the end of its recess under the raised housing, a constriction whose size and shape are substantially equal to those of the fastener at its branches.
  • FIGS 1 and 2 of the accompanying drawings show a device for elastic fastening of a track device rail, in particular of a needle rail fixed 1 of switches cooperating with a movable needle rail 2 which can move transversely to the track, these rails resting on a sliding bearing 3, the needle rail 1 being held on the bearing 3, on the one hand, on the outside of the track by a fixing means 4 and, on the other hand, on the inside of the track by an elastic fastener 5 substantially in the shape of a U, arranged in a recess 6 of the bearing 3 and the ends of the branches 7 of which penetrate, tensioning position of the elastic fastener 5 by means of a stop 8 ensuring the effort of plating the needle rail 1 on the bearing 3, in raised housings 9 provided for this purpose in said cushion 3.
  • the bearing 3 further comprises, at the end of its recess 6 under the raised housing 9, a constriction 10 whose size and shape are substantially equal to those of the fastener 5 at its branches 7.
  • This throttle 10 is designed to ensure at least partial insertion of the fastener 5 to its normal longitudinal position and, preferably, a perfect longitudinal positioning of said fastener 5.
  • each housing 9 has a slope 11 for longitudinal positioning of the fastener 5.
  • its branches 7 are found on these slopes 11 during the setting in tension of the fastener 5, forcing it to position correctly longitudinally.
  • the pad 3 is provided, substantially below the raised housing 9, with two additional housings 12.
  • the length of these housings 12 advantageously corresponds to that of the raised dwellings 9 increased by the length of the corresponding longitudinal positioning slopes 11, so that it is such that they can still receive the ends of the branches 7 of fastener 5 even if it could not be fully inserted into the recess 6 of the bearing 3.
  • These additional housings therefore allow stable positioning of the ends of the branches of the fastener 5, even in their intermediate position.
  • the pad 3 includes a spout 13 provided with lateral reinforcements allowing the recovery of forces during the tip needle rail 1.
  • Each reinforcement of the spout 13 is at a distance h2 from the shoe 14 of the counter-needle rail 1 less than a distance h1 separating the head 15 from the fastener 5 of the upper surface of the recess 6 of the bearing 3. It results from this mode of realization that the head 15 of the fastener 5 can in no case be found compressed between the upper surface of the recess 6 of the bearing 3 and the shoe 14 of the needle rail 1 when it spills, so that all jamming of said fastener in this position is avoided.
  • said pad 3 has, in accordance with another characteristic of the invention, a main ramp 16 ending in two lateral ramps 17.
  • the head 15 of the fastener 5 always tends to be oriented in a movement of uprising naturally causing its underside to slide unhindered over the upper face of shoe 14.
