Definitions

  • This device is used effectively in the railway sector. It is used in the field of armament deviators activated by control boxes fitted either to wooden or reinforced concrete beams.
  • a train deviator is composed of two parts: a crossover and a changeover.
  • the latter is composed of needles which are made from specially treated tracks which are thinned at one end so that the needle end can be hidden under the adjacent railheads, which are known as counterneedles.
  • These needles are mobile; in order to facilitate their movement, they are made to run across a series of steel bearings which are fitted to the deviator's beams.
  • bearings require lubrication in order to reduce friction between the needle and the surface of the bearings.
  • This operation is carried out by railway personnel by applying thick oil or grease to the bearings on a weekly or fortnightly basis.
  • the purpose of the invention in question is creating a device capable of allowing the needles to run across the bearings without there having to be the need for regular bearing lubrication.
  • the present device which is composed of a U-shaped metal support; symmetrical holes are drilled on either side of the U-shaped metal support.
  • One or more pivots, on which as many stainless steel rollers lie, are placed inside the aforementioned holes.
  • rollers rotate around a horizontal axis and are internally fitted with self-lubricating, plastic ferrules or with roller or ball bearings. These ferrules or bearings are placed on the same axis of the aforementioned rollers.
  • the support is composed of a horizontal, quadrangular base and by the aforementioned vertical sides. The pivots are fixed to these sides by means of a series of soldered points or by using any other rigid, but easily-removable system.
  • the support is placed on a series of accessories, such as a quadrangular supporting plate and shims consisting of small quadrangular metal plates.
  • Pivot-blocking carried out by means of the aforementioned soldered points or any other easily-removable, rigid system allows worn pivots and rollers to be removed easily and replaced with new ones; the support is therefore recyclable.
  • the device here described is composed basically of a U-shaped metal support 1 on which one, two or three stainless steel rollers 2 with a horizontal rotating axis are fitted.
  • the support 1 is composed of a rectangular horizontal base 3 and by two normal sides 4 on this base 3. On said sides 3 there are symmetrical holes in which the extremities of one, two or three pivots 5 are placed.
  • the support 1 is placed on a quadrangular supporting plate 7; the height of the rollers 2 from the running surface of the bearings 8 is adjusted by placing between the supporting plate 7 and the base 3 of the support 1 a series of shims 9 consisting of quadrangular, metal plates, one-two mm in thickness.
  • the support 1 is secured to the shims 9 and to the plate 7 by means of screws 10.1. All these components are then secured to the beam 11 by means of screws 10.2 so that the generator of the roller 2 is approximately two millimetres higher than the running plane of the bearing 8.
  • the purpose of adjusting the height of the rollers 2 by using shims 9 is allowing the support 1 and rollers 2 to be used, both according to the various pre-existing types of fittings and to the varying degrees of wear of the beam 11, before the device in question is installed. Furthermore, in the long run, this adjustment allows the inevitable wear of the system comprising the roller 2 - pivot 5 - ferrule 6 to be compensated for.
  • the pivots 5 are fixed to the sides 4 by means of a series of soldered points.
  • the aforementioned screws 10.1, 10.2 are placed in holes drilled in the base 3, in the shims 9 and supporting plate 7.
  • the holes used to secure the single-roller device to the beam 11 and those used to secure the double-roller to the beam 11 share the same interaxis; as a result, in both cases the supporting plate 7 and the shims 9 are the same in size.
  • the support 1 and its accessories are placed next to the bearing 8 so that the sides of these components are in direct contact with one another. Once this has been carried out, the screw 10.2 - which allows the support 1 to be fixed to the beam 11 - will be placed in the vicinity of the shorter side of the base 3 and will prevent the support 1 from rotating.
  • the double or triple-roller device Given stroke of the needle 12 and the width of the flange of the needle 12 itself, the double or triple-roller device will be placed near the bearings 8 located near the top of the train deviator. On the other hand near the rear end of the deviator, the single or double-roller device will be used.
  • the following single or double-roller devices will be placed next to every four or five bearings 8, in other words every three/four metres.
  • the needle 12.2 - moved away from the counter-needle 13.2 - begins its stroke on the rollers 2 and is set on the bearings 8 when it is a few millimetres away from the counter-needle 13.2.
  • the support 1 can be re-cycled.
  • the pivots 5 and rollers 2 are worn out, by removing the soldering points, the pivots 5 and rollers 2 can be removed and replaced with new ones.
  • the above variations include the position of the means used to secure the device in question to the beam 11.
  • Figures 7, 8 and 9 show a triple-roller device which is secures to the beam 11 by means of headless screws 10.3 with a hexagon embedding and ferrules 14.
  • the ferrules 14 are fitted to the beam 11 in advance.
  • the holes, into which the screws 10.3 are fitted, are drilled in the base 3, plate 7 and shims 9.
  • the support 1 is also placed on the plate 7; height adjustments are made on the rollers 2 regarding the running plane of the bearings 8 by placing various metal quadrangular plate shims 9 between the supporting plate 7 and the base 3 of the support 1.
  • the support 1, shims 9 and plate 7 are secured to the beam 11 by means of the headless screws 10.3 with a hexagon embedding which enter the ferrules 14.
