Definitions

  • the present invention relates to a switch for grooved rails or rut for rail traffic, constituted by a profiled cradle forming the housing of a movable deflection needle, as well as the rolling and guide surfaces and allowing the operation of the needle, the cradle being constituted by a profiled body produced by machining by removing chips.
  • the invention relates more particularly, without being limited thereto, to switches for urban transport or port facility railways, the rails of which are embedded in the covering of the road network.
  • Patent LU-87 503 proposes a new method for manufacturing switches of the type described above, which is entirely carried out by machining exclusively by removing chips.
  • This switch manufacturing process has many advantages, including that of being able to be carried out automatically under programmed control, of being able to deprive oneself of welds and of not having either to have a large stock of spare parts, or to be dependent on the supply of these parts.
  • patent LU-87,721 proposes to keep the needle rail and to associate it, after removal of the inner part of its feet, by bolting to the machined body.
  • the object of the present invention is to provide an improved switch, semi-assembled and semi-machined, in which the non-machined parts are standard parts and which allows more reliable operation of the needle.
  • the invention provides a switch of the kind described in the preamble, which is essentially characterized in that the body is bolted between a counter-needle rail and an opposite rail, both of which lack their adjacent foot on any the length of the body, in that the counter-needle rail is devoid of its rut on the mobility length of the needle and in that the upper surface of the body supporting the movable part of the needle is profiled so as to present flat needle support bearings alternating with notches machined in the body.
  • the switch proposed by the present invention also makes it possible to reduce time and machining waste.
  • Figure 1 shows a pair of rails 10, 12 which are extended by a switch 14 for guiding a convoy, either on the pair of rails 10a, 12a, or on the pair of rails 10b, 12b.
  • the switch works in a conventional manner, only its manufacturing process and, consequently, the profile of the parts used are distinguished from the state of the art. This is illustrated by the different sections according to Figures 2 to 6.
  • Figure 2 shows a cross section of the switch at the point of a needle 18.
  • the housing of the needle 18 is delimited by a body 20 supporting the needle 18 a needle rail 22 and an opposite rail 24 which are deprived of the inner part of their foot and which are bolted to the body 20 by means of bolts 26 as shown in FIG. 3.
  • the body 20 is produced by machining, preferably by automatic milling under programmed control.
  • the part of the body 20 supporting the movable part of the needle 18 is, as shown in FIG. 7, in the form of a succession of bearings 28 and notches 30 separating the bearings 28.
  • Each bearing 28 has a perforation 32 allowing the passage of the bolts 26.
  • the purpose of these notches 30 is to recover foreign bodies, such as stones and gravel, or the like, which, without the presence of the notches could hinder the proper functioning of the needle 18.
  • the surface of the notches 30 is preferably greater than the surface of the bearings 28.
  • the body 20 comprises a longitudinal machined channel 34 allowing the flow of cleaning water and rain water.
  • the needle rail 22 can be formed by rail 10, 10a or rail 12, 12b of the existing track or by a rut rail welded to the latter. Over the length of the mobility of the needle 18 the needle rail 22 must be deprived of its rut to allow the operation of the switch. Beyond the area of activity of the needle 18 the needle rail 22 must, of course, have its rut 36 as shown in Figure 4 and following.
  • the rail 24 can also be stripped of its rut over the entire length of the switch. As shown in the figures, the two rails 22 and 24 retain, over the entire length, the outer part of their foot, which contributes to better symmetry and the integration of standard elements.
  • Reference 44 designates an electrical heating resistance. This is held in place by profiled washers 38 associated with the fixing bolts 26.
  • the two rails 22 and 24, as well as the needle 18, are drilled horizontally to allow the installation of the means of maneuvering, not shown, of the needle 18.
  • the invention therefore makes it possible to reduce a non-negligible part of the machining necessary for the manufacture of a one-piece switch, by taking advantage of the existence of the counter-needle rail 22 and the opposite rail 24.
  • These two rails are standard profiles. from which it suffices to remove, by machining, the interior part of the foot and the rut.
  • These two parts can also be replaced individually and separately, which is all the more advantageous since they are the parts most vulnerable to wear.
  • FIGs 4, 5 and 6 show sections through the rear part of the switch where the machined body 20 has an edge 20a widening gradually and rising to the upper level of the switch. This edge 20a ensures the separation between the needle rail 22 and the needle 18.
  • the heel of the needle 18 is fixed in the body 20 using a key 40. This is, in turn, wedged using a bolt 42 anchored in the body 20. To allow tightening of the bolt 42, the head of the rail 24 is removed at this location (see FIG. 4).
  • Figure 6 shows a section at the end of the switch at the junction between the needle 18 and the rail 10b.
