Definitions

  • the present invention relates to the field of railway infrastructure, in particular track materials, in particular tramway, and relates to a device for fixing a counter-needle rail to a switchgear, such as a block of semi-switching consisting of an assembly of rails and other profiles.
  • Point switches and turnouts in particular used in the field of tram track equipment infrastructure, which are subject to less stress than those to which railway track apparatus is subject, They are generally made in the form of mechanically welded assemblies which, admittedly, have lower performances, but which have a much lower cost price.
  • Such a counter-needle rail welding which is made of a heat treated steel grade, is difficult to perform directly on the other components of the rail assembly and other welded sections.
  • the rail is preheated in the vicinity of the zone to be welded, at a temperature of the order of 300 ° C. to 350 ° C., followed by rapid welding followed by very slow cooling. of the assembly thus obtained.
  • Such a welding method has a number of disadvantages, namely, firstly, that the initial preheating of the counter-needle rail is long and difficult to perform, the reference temperature must not be exceeded and all locations solder must be heated at the same time and, secondly, that during preheating, the rail is deformed and must deploy many devices that must be maintained by a third person.
  • the preheating can practically be achieved with the aid of a torch, which is dangerous for the third person assisting the operator performing the welding.
  • a device for fixing the counter-needle rail using metal rings provided with a flange and through corresponding holes in the web of the counter-needle rail.
  • These metal rings have a length between their free end and the flank of the flange less than the thickness of the web of the counter-needle rail, so that their free end extends away from the welded components of the switchgear.
  • These metal rings are welded by a plug-type weld, at their free ends on said mechanically welded components of the switchgear.
  • the assembly obtained according to this document WO 00/65154 does not present any flexibility and the stresses applied in the case of lateral forces are transmitted directly to the weld closest to the point of application of the corresponding load, which can cause fatigue failure at said weld.
  • the rings are welded on the end of the cross members, by their outer face, so that during the removal of the weld bead after welding, said rings tend to be spaced from the rails against which they are tightened before welding.
  • the object of the present invention is to overcome these drawbacks by proposing a device for fixing a counter-needle rail to a switchgear, such as a half-switch block composed of a rail assembly allowing a certain flexibility in the assembly of the counter-needle rail on the mechanically welded assembly and thus a better resistance to fatigue under lateral load.
  • a switchgear such as a half-switch block composed of a rail assembly allowing a certain flexibility in the assembly of the counter-needle rail on the mechanically welded assembly and thus a better resistance to fatigue under lateral load.
  • the device for fixing a counter-needle rail to a switchgear such as a half-switch block consisting of a rail assembly and other profiles, is characterized in that it consists of less a conical bearing ring forcibly inserted into a conical bore corresponds to the counter-needle rail and welded to the profile assembly.
  • FIG. 1 represents, by way of example, a half-switch unit of a switchgear consisting of a needle 1 mounted on a sliding plate 2, said sliding plate 2 being itself mounted on a reinforcement vertical 3 and on a needle cover 4, the needle assembly 1, sliding plate 2, vertical reinforcement 3 and needle cover 4 being welded to a base plate 6.
  • this half-switching block is fixed, by means of a fastening device 7 , a counter-needle rail 5.
  • the fastening device 7 of the counter-needle rail 5 on the switch unit half-switch block consists of at least one conical bearing ring 7 'forcibly inserted in a conical bore corresponding to 7 " of the counter-needle rail 5 and welded to the profile assembly forming the half-switching block, via a weld 8 internal to the conical bearing ring 7.
  • each conical bearing ring 7 ' is force-fitted into the corresponding conical bore 7 ", by irreversible clamping and is leveled at the inner face 5' of support of the counter rail. needle 5 against the assembly of sections forming the half-switch block of a switchgear.
  • the irreversible tightening of the conical bearing ring 7 'in the corresponding conical bore 7 " is obtained by predicting a taper angle of the bore 7" and the corresponding surface of the ring 7', whose determination is within reach of the skilled person and does not require any further explanation.
  • the angle of conicity must be provided such that the conical bearing ring 7 "can be pressed into the corresponding bore 7" so that it is permanently maintained during all the preparatory phases for the final assembly of the counter Needle with the other components of the half-turn block of the switchgear.
  • the assembly of the conical bearing ring 7 'to the counter-needle rail 5 is performed by means of a press and the clamping obtained requires no implementation of additional holding means.
  • the fastener according to the invention makes an assembly with a perfect contact, without play, but also without any unnecessary clamping effect of said counter-needle rail 5 against the assembly of profiles, so that such an assembly is more durable than existing assemblies to date.
  • the invention it is possible to achieve a fastening of a counter-needle rail on a half-switch block of a switchgear by implementing an assembly of less rigidity than that of the solutions. to date, so that the performance of the whole of the switchgear is improved, and in particular the resistance to the fatigue test under lateral load.
