Definitions

  • the present invention relates to a switch for grooved rails or rut constituted by a profiled cradle forming the housing of a movable deflection needle, as well as the rolling and guide surfaces and allowing the installation of the means necessary for the operation of the needle.
  • 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 surface of the road network.
  • Patent LU 87.503 proposes a new method for manufacturing switches of the type described above and according to the preamble of the appended single claim, which is entirely carried out by machining exclusively by chip removal. This method of manufacturing switches has many advantages, one of the most important of which is that it can be performed automatically under programmed control.
  • the object of the present invention is to provide an improved switch which has all the advantages of the switch obtained according to the aforementioned Luxembourg patent but which, in addition, allows an improvement in the yield and a significant reduction in machining waste.
  • the invention relates to a referral according to the appended single claim.
  • the machining time of such a switch is significantly reduced, which increases the production capacity.
  • the heat treatment before the assembly of the constituent parts is easier.
  • Reconditioning is also easier, in particular by replacing the needle rail after wear.
  • the size of the steel blocks required for machining can also be reduced.
  • 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 is 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 a referral cradle 16 at the point of a needle 18.
  • the cradle is formed by a body 20 and a needle rail 22 , bolted to each other, in several places using bolts 23.
  • the body 20 is produced in accordance with the method proposed by patent LU 87.503, that is to say, by machining, preferably, by automatic milling under programmed control.
  • the needle rail 22 to which the body 20 is bolted may be formed by rail 10, 10a or rail 12, 12b of the existing track or by a rut rail welded to the latter.
  • the needle-guide rail 22 has its rut 24 as shown in FIGS. 5 and 6, while in the part of the switch where the needle 18 is movable to exercise its deflection functions, the rail 22 is devoid of its rut as shown in Figures 2 to 4.
  • the head of rail 22 defines with an appropriate profile of the body 20 produced by milling a groove forming the housing of the needle 18.
  • the needle rail 22 is also devoid of the foot adjacent to the body 20 to allow bolting of the latter on the rail 22.
  • the removal of the foot of the rail 22 and its rut 24 can be made by milling or sawing.
  • the invention therefore makes it possible to reduce a non-negligible part of the machining proposed in the aforementioned patent by taking advantage of the existence of the counter-needle rail 22, the operation of removing the rut 24 and the base of the rail being largely offset by the gain in machining.
  • the machined body 20 may have, as in the aforementioned patent, an inner longitudinal groove, not shown, for the passage of the heating pipe.
  • Figures 3 and 4 correspond to the same figures of the aforementioned patent and respectively show a vertical hole 28 through the body 20 for the evacuation of rainwater and rinsing and a horizontal bore 30 intended to receive the maneuvering means of the needle 18.
  • Figure 5 shows a section at the end of the switch in the region where the needle 18 is wider and where it is connected to the rails of the track.
  • Figure 6 shows a section at the junction with the rail 10b which, in order to be bolted to the body 20 and to the needle rail 22 is also devoid of its foot on the side adjacent to the body 20.
  • the raw material for the production of the body 20 is a rolled, forged or molded bloom, the quality of the steel of which can be easily determined by the manufacturer of the switch. These blooms are preferably cut lengthwise and obliquely so as to be able to produce, using a single bloom, two referral bodies 20 in application of the teaching provided by the aforementioned patent. After machining, it is possible to subject the body 20 to a heat treatment, or to localized quenching to achieve surface hardening of the parts most exposed to stresses. It is also possible to perform surface reloading by welding to locally increase the resistance. In the event of wear of the needle rail 22, it is possible to cut the latter, to unbolt it from the body 20 and to replace it without requiring replacement of the body 20.
