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 for making such an installation.
- Such a cradle is generally constituted by a one-piece element, preferably made of manganese steel, and by an element formed by rails joined to the part monobloc by welding, or by any other form of assembly, said element being stiffened by plates placed from below.
- the installation of the movable point in the cradle is particularly important in appliances 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 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 an element monobloc and an element constituted by two rails and connected to the movable point by a bonded assembly.
- a relationship mechanical between the moving tip and the two rails of the cradle is also known from AT-A-343 711.
- EP-A-0 282 796 and EP-A-0 298 950 describe a mechanical connection between the tip and the hare's feet with a fixed point crossing heart.
- the object of the present invention is to overcome this disadvantage by proposing a recess of the point movable in the cradle of an incorporated crossing heart in long welded rails, providing a connection durable between the different elements and preventing any risk of rupture of the clamping means.
- the invention also relates to a method for carrying out the installation, characterized in that it includes a temporary assembly phase for the various elements of the moving point and the cradle of the heart of crossing and a final phase of setting up 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 the long welded rails, said recess allowing the transmission of forces of expansion of the rails of current track to said cradle, while absorbing the forces due to vehicle rolling, said cradle 2 being composed of two elements, know a monobloc element 2 'and a 2 "element made up by two rails 3 and 4 and connected to the monobloc element 2 ' by welding or any other form of assembly, the connection between the moving tip 1 and the 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 a significant part of the effort of traction or compression generated by long welded rails is transmitted by friction of spacers 5 and 6 integral with the moving tip 1 and the element 2 " of the cradle formed by the two rails 3 and 4
- High strength bolts 7 and 8 cooperate with 5 ', 5 “and 6', 6" sections of 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, whose heads 8 ′ are supported by means of parts 13 on the external faces rails 3 and 4 and including the nuts 7 "and 8", as well as the heads 7 ′ of the bolts 7 bear on the profiles 5 ', 5 "and 6', 6" from spacers 5 and 6 via washers 14 and, on the other hand, shear with longitudinal forces, by resumption of longitudinal stresses in the event of cancellation of the friction.
- the cotter pins cross the rails 3 and 4 and the movable tip 1 by means of holes, whose diameters are barely smaller than those of said pins. It follows that the longitudinal displacements rails relative to the crossing core are extremely limited. In addition, the longitudinal forces shear are taken up by the split pins 11 and 12, so that 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 tensile or compressive force generated by the 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, cotter pins 11 and 12 are capable to absorb the overall effort by shearing.
- the invention also relates to a method for carrying out the installation, characterized in that it includes a temporary assembly phase for the various elements of the moving point 1 and the cradle 2 of the heart crossing and a final phase of setting up removable mechanical connection means.
- the process consists of fix the 5 "and 6" profiles on the tip 1, the profile 5 'on rail 3 and profile 6' on rail 4, to be positioned with precision point 1 and rails 3 and 4, at present the bars 9 and 10 and bring them together respectively 5, 5 "and 6 ', 6" profiles with weld, then remove the spacers 5, 6, spreading rails 3 and 4, as shown in FIG. 4, and, finally, to permanently weld the bars 9 and 10.
- the final phase of the process consists in putting in place the split pins 11 and 12, to install the spacers 5 and 6 and fix them with the bolts high resistance 7 and 8.
- the embedding device according to the invention is applicable to a moving tip core, of which the tip 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 rail profiles asymmetrical section.
