Definitions

  • the present invention relates to the field of construction of railway track equipment, in particular crossing hearts, and has for its object the embedding of the movable point in the cradle of a crossing heart incorporated in long welded rails.
  • the invention also relates to a method for producing such an embedding.
  • Such a cradle is generally constituted by a monobloc element, preferably made of manganese steel, and by an element formed by rails joined to the monobloc part by welding, or by any other form of assembly, said element being rigidified by plates. posed from below.
  • the embedding of the movable point in the cradle is particularly important in devices incorporated in long welded rails, because they are stressed by vertical forces due to the passage of vehicles and by traction or compression forces due to variations in long welded rails.
  • the present invention aims to achieve an essentially mechanical connection between the movable tip and the cradle.
  • Its purpose is, in fact, to embed the movable point in the cradle of a crossing core incorporated in the long welded rails, said cradle being composed of two elements, namely a one-piece element and an element constituted by two rails and connected to the monobloc element by welding or by any other form of assembly, characterized in that the connection between the movable point and the element of the cradle constituted by two rails is produced by an assembly essentially mechanical.
  • the subject of the invention is also a method of producing the embedding, characterized in that it comprises a provisional phase for mounting the various elements of the movable tip and the cradle of the crossing core and a final phase for placing the removable mechanical connection means.
  • the embedding of the movable tip 1 in the cradle 2 of a crossing heart incorporated in the long rails welded said cradle 2 being composed of two elements, namely a one-piece element 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, is characterized in that the connection between the movable point 1 and the element 2''of the cradle consisting of two rails 3 and 4 is produced by an essentially mechanical assembly.
  • This assembly is advantageously carried out by means of spacers 5 and 6 fixed, on the one hand, to the movable tip 1 by means of high-strength bolts 7 and, on the other hand, to the rails 3 and 4 of the 'element 2' of the cradle 2 by means of high-strength bolts 8 ( Figure 2).
  • the spacers 5 and 6 are each in the form of a pair of profiles 5 ', 5' 'and 6', 6 '' resting at the bottom of the web of the rails and freeing jointing surfaces for the purpose of tightening the high-strength bolts allowing a significant friction force to be obtained soul on soul, the sections 5 ', 5' 'and 6', 6 '' of each pair being connected to each other respectively by means of bars 9 and 10.
  • the high-strength bolts 7 and 8 cooperate with the profiles 5 ', 5' 'and 6', 6 '' of the spacers 5 and 6 and with the rails 3 and 4 by means of split pins 11 and 12, made of spring steel , serving, on the one hand, sheath to said bolts 7 and 8, whose heads 8 'are supported by means of parts 13 on the external faces of the rails 3 and 4 and whose nuts 7' 'and 8' ', as well as the heads 7' of the bolts 7 bear on the profiles 5 ', 5' 'and 6', 6 '' of the spacers 5 and 6 by means of washers 14 and, on the other hand, of part of shear to longitudinal forces, by resumption of longitudinal stresses in the event of friction cancellation.
  • the split pins pass through the rails 3 and 4 and the movable point 1 by means of holes, the diameters of which are barely greater than those of the said pins.
  • the longitudinal displacements of the rails relative to the crossing core are extremely limited.
  • the longitudinal shearing forces are taken up by the split pins 11 and 12, so that the high-strength bolts 7 and 8 are only stressed under tension.
  • the spacers 5 and 6 transmit by friction, from the tip 1 to the cradle 2, a large part of the tensile or compressive force generated by the long welded rails. The rest of these forces are absorbed by the shear strength of the split pins 11 and 12 made of spring steel forming the sleeves of the bolts 5 and 6.
  • the assembly of the recess according to the invention is designed in such a way that in the event of friction cancellation, the split pins 11 and 12 are capable of absorbing the overall force by shearing.
  • the invention also relates to a method for producing the embedding, characterized in that it comprises a provisional phase of mounting the various elements of the movable tip 1 and the cradle 2 of the crossing core and a final phase of setting place of removable mechanical connection means.
  • the process consists in fixing the 5 '' and 6 '' profiles on the tip 1, the 5 'profile on the rail 3 and the 6' profile on the rail 4, to precisely position the tip 1 and the rails 3 and 4, to present the bars 9 and 10 and to bring them together respectively to the sections 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 permanently bars 9 and 10.
  • the final phase of the process consists in installing the split pins 11 and 12, in placing the spacers 5 and 6 and in fixing them using the high-strength bolts 7 and 8.
  • the embedding device according to the invention is applicable to a core with a movable point, the point 1 and the rails 3 and 4 of which are of different height, as shown in FIGS. 5 and 6.
  • the invention is applicable to constructions whose tip 1 and / or rails 3 and 4 are made of rail profiles with asymmetrical section.
  • the device according to the invention is also applicable to a crossing core with a fixed point.
  • the invention it is possible to embed the movable point 1 in the cradle 2 of a crossing core incorporated in the long welded rails and subjected to high compression and tensile forces generated by temperature variations in said long welded rails.
