Definitions

  • the present invention relates to the field of construction of railway track equipment, in particular the crossing hearts, and has for object a embedding of the movable point in the cradle of a crossing heart incorporated in the long welded rails.
  • the invention also relates to a method of realization of such embedding.
  • Such a cradle is generally constituted by a monobloc element, preferably in manganese steel, and by an element formed by rails joined to the monobloc part by welding, or by any other form assembly, said element being stiffened by plates posed from below.
  • the installation of the movable point in the cradle is particularly important in built-in devices in long welded rails, because they are stressed by vertical forces due to the passage of vehicles and by tensile or compressive forces due to temperature variations in long welded rails.
  • EP-A-0 365 450 a recess of the moving point in the cradle of a crossing heart incorporated into the long welded rails, said said cradle being composed of two elements, namely a monobloc element and an element constituted by two rails and connected to the movable point by a glued assembly.
  • a mechanical connection between the movable tip and the two cradle rails is also known by AT-A-343 711.
  • EP-A-0 282 796 and EP-A-0 298 950 describe a mechanical connection between the tip and the legs hare from a crossing heart with fixed point.
  • the object of the present invention is to overcome this drawback by proposing a recess of the point movable in the cradle of an incorporated crossing heart in the long welded rails, allowing to obtain a lasting bond between the different elements and preventing any risk of rupture of the clamping means.
  • the invention also relates to a method of realization of the embedding characterized in that it includes a temporary assembly phase for the various elements of the moving point and the cradle of the crossbreed and a final phase of implementation place of removable mechanical connection means.
  • FIGS. 1 to 4 of the accompanying drawings the embedding of the movable point 1 in the cradle 2 with an incorporated crossover heart in long welded rails, said embedding allowing the transmission of the expansion efforts of common track rails to said cradle, while absorbing forces due to the rolling of vehicles, said cradle 2 being composed of two elements, namely an element monobloc 2 'and a 2 "element constituted by two rails 3 and 4 and connected to the monobloc element 2 'by welding or by any other form of assembly, the connection between the point mobile 1 and element 2 "of the cradle consisting of two rails 3 and 4 being produced by an assembly essentially mechanical by means of bolts 7, is characterized in that that a significant part of the traction or compression force generated by the long welded rails is transmitted by friction of spacers 5 and 6 integral with the movable tip 1 and the element 2 "of the cradle formed by the two rails 3 and
  • Mechanical assembly between the moving tip 1 and the element 2 "of the cradle constituted by the two rails 3 and 4 is advantageously produced by means of spacers 5 and 6 fixed, on the one hand, on the movable point 1 by through high-strength bolts 7 and, on the other hand, on the rails 3 and 4 of the element 2 "of the cradle 2 via high strength bolts 8 ( Figure 2).
  • Spacers 5 and 6 are each presented in the form of a pair of 5 ', 5 "and 6', 6" profiles supported at the bottom of the rail core and freeing spans for tightening the bolts at high resistance allowing a friction force to be obtained important soul on soul, the 5 ', 5 "and 6', 6" profiles of each pair being interconnected respectively by means of bars 9 and 10.
  • High strength bolts 7 and 8 cooperate with profiles 5 ', 5 “and 6', 6” from spacers 5 and 6 and with rails 3 and 4 by means of cotter pins 11 and 12, made of spring steel, serving, on the one hand, as a sheath to said bolts 7 and 8, the heads 8 'of which are supported by parts 13 on the external faces of the rails 3 and 4 and including the nuts 7 "and 8", as well as the heads 7 'of the bolts 7 are supported on the sections 5', 5 "and 6 ', 6 "spacers 5 and 6 via washers 14 and, on the other hand, shear part to longitudinal forces, by resumption of longitudinal stresses in the event of friction cancellation.
  • the cotter pins cross the rails 3 and 4 and the movable tip 1 by means of holes, of which the diameters are barely smaller than those of said pins. It follows that the longitudinal displacements rails with respect to the crossing core are extremely limited. In addition, the longitudinal forces shear are taken up by the split pins 11 and 12, so the high-strength bolts 7 and 8 are only applied to traction.
  • the spacers 5 and 6 transmit by friction, from point 1 to cradle 2, a significant part of the effort of traction or compression generated by long welded rails. The rest of these efforts are absorbed by the shear strength of the split pins 11 and 12 in spring steel forming the sheaths of bolts 5 and 6.
  • the assembly of the recess according to the invention is designed in such a way that in the event of cancellation friction, the cotter pins 11 and 12 are capable of absorbing the overall force by shearing.
  • the invention also relates to a method of realization of the embedding characterized in that it includes a temporary assembly phase for the various elements of the moving point 1 and the cradle 2 of the crossbreed and a final phase of implementation place of removable mechanical connection means.
  • the process consists of fix the 5 "and 6" profiles on the tip 1, the 5 'profile on rail 3 and profile 6 'on rail 4, to be positioned with point 1 and rails 3 and 4, to present the bars 9 and 10 and to join them respectively to the profiles 5, 5 "and 6 ', 6" by welding points, then to deposit the spacers 5, 6 by spreading the rails 3 and 4, as shown in Figure 4, and finally to weld definitely bars 9 and 10.
  • the final phase of the process consists in places the split pins 11 and 12, made of spring steel to install the spacers 5 and 6 and fix them with the high bolts resistance 7 and 8 the pins 11 and 12 passing through the rails 3 and 4, the moving point 1 and the spacers 5 and 6.
  • the embedding device according to the invention is applicable to a moving tip core, the tip of which 1 and the rails 3 and 4 are of different height, as shown in Figures 5 and 6.
  • the invention is applicable to constructions whose tip 1 and / or rails 3 and 4 are made of asymmetrical section rail profiles.
