Definitions

  • the present invention relates to the field of sleeper fixing mechanisms for railway rail support and more particularly to the field of adjustable sleeper fixing mechanisms.
  • the running rails are mounted on sleepers that help maintain their gauge and cant. These sleepers also ensure the transmission of loads from the vehicles running on the rails to the supporting structure.
  • the sleepers are laid on a layer of ballast made from a compact mixture of crushed stone and sand.
  • the sleepers are mounted directly onto the structure, typically using a pair of fastening points at their ends.
  • Each fastening point is usually a spike screw driven through the thickness of the sleeper; the lower end of the screw screw is mounted or fixed directly to the structure.
  • the installation of the sleepers, and in particular the positioning of the fastening points on the structure is constrained by the structural arrangement and/or architecture of the structure. The positioning of each fastening point on the sleepers, and their respective spacing, is therefore dependent on the constraints imposed by the supporting structure of the engineering structure.
  • each sleeper and in particular the position of its fixing points along its length, must be prepared according to the specific location assigned to said sleeper on the engineering structure, prior to its installation on that structure.
  • Such a solution thus necessitates a laborious analysis of the position of each sleeper on the section of railway track crossing the engineering structure.
  • the publication US 4795091A offers a device that allows adjustment of the The fixing of a crossbeam to the structure of an engineering work depends on the position of the through-bolt mounted within the thickness of the crossbeam. While this solution allows for some tolerance in the position of the crossbeam's holes that house the bolts, it relies on an indirect fixing to the structure of the engineering work, without anchoring the bolt at any through-bolt point in the structure.
  • the present invention aims to overcome these drawbacks by proposing a mechanism for fixing a cross member to a support structure which makes it possible to limit, or even eliminate, the need to prepare each of the cross members intended to be installed on a support structure according to the fixing position constraints imposed by the respective location of each of the cross members on the support structure.
  • the invention relates to an assembly as detailed in the statement of main claim 1. Different variants of the invention are defined in particular by the secondary claims.
  • the device of the invention can be implemented at only one of the two ends of a cross member 1, the other end comprising a known type of lag screw fastener.
  • the device of the invention is then sufficient to secure the cross member 1 by adjusting a single anchor point. Adjusting this single anchor point of the cross member 1 allows for setting the spacing between the anchor points positioned at each end of the cross member 1.
  • each end of a cross member 1 is associated with a device for adjusting the anchoring of the cross member 1 to a support structure 2.
  • the orientation of the grooves of this pair of grooved arrangements 42, 72 is substantially arranged perpendicular to the axis of the cross member 1.
  • Such an arrangement of the grooves thus makes it possible to obtain cooperation of the reliefs, so that any translational displacement likely to be supported by the cover piece 4 is blocked by the cooperation of reliefs of the grooved arrangements 42, 72. These reliefs then support the shear forces of the cover piece 4 with respect to the cross member 1.
  • the complementary grooved arrangement 72 is supported by the upper surface of the cross member 1. In this way, the translation of the cover piece 4 against the upper surface of the cross member 1 is blocked and prevents any movement along the axis of the cross member 1. The cover piece 4 is then directly supported against the upper surface of the cross member 1.
  • the dimensions of the cover piece 4 are adapted to those of the upper surface of the cross member 1 so as not to prevent the placement of the orifice 41 of the cover piece 4 in overlap with any point on the surface of the orifice in the cavity 11. Also, the upper surface of the cross member 1 does not contain any obstacle to the positioning of the cover piece.
  • the complementary grooved arrangement 72 is supported by the upper surface of an intermediate piece 7 bearing against the upper surface of the cross member 1.
  • This intermediate piece 7 comprises an opening 71 with dimensions substantially similar to those of the upper opening of the cavity 11 of the cross member 1 through which the anchoring pin 3 passes.
  • Preventing the sliding of the cover piece 4 relative to the upper surface of the cross member 1 involves clamping the cover piece 4 to the cross member 1, so that the intermediate piece 7 is positioned superimposed between the cover piece 4 and the cross member 1.
  • the intermediate piece 7 is integrated into the cross member 1 and more particularly with the upper surface of the cross member 1, for example by overmolding.
  • the upper surface of the cross member 1 includes at least one locking device 8 to prevent the intermediate piece 7 from sliding relative to the cross member 1.
  • This locking device 8 prevents any unwanted sliding or translation of the intermediate piece 7 relative to the cross member 1, and in particular any sliding or translation along an axis perpendicular to the axis of the cross member 1. Under these conditions, locking the intermediate piece 7 with the cross member 1 prevents any inappropriate movement of the cover piece 4 relative to the cross member 1 when this cover piece 4 interacts with the intermediate piece 7 through the cooperation of the grooved arrangements 42, 72.
  • the sliding blocking device 8 for the intermediate piece 7 comprises at least one piece fixed to the upper surface of the cross member 1 and having at least one edge 81 abutting against an edge of the intermediate piece 7.
  • This abutting piece 8 thus creates a raised feature on the upper surface of the cross member 1, forming an obstacle to the movement and/or translation of the intermediate piece 7 relative to the cross member 1, particularly along the axis of the cross member 1.
  • This piece 8 is therefore able to withstand the various shear forces that can be exerted by the intermediate piece 7 against the upper surface of the cross member 1.
  • this blocking device 8 is positioned against the edge of the intermediate piece 7.
  • the blocking device 8 is implemented as a pair of stops positioned on either side of the intermediate piece 7, such that each opposite edges of the middle piece 7 is in contact with a stop of the locking device 8.
  • the pair of stops and the intermediate piece 7 are aligned along the axis of the cross member 1.
  • this locking device 8 may take the form of one or more pieces mounted on the upper surface of the cross member 1 and/or take the form of a relief or pieces integrated into the cross member 1 and in particular into the upper surface of the cross member 1.
  • the locking device 8 for preventing the intermediate piece 7 from sliding incorporates a housing forming a cavity in the upper surface of the cross member 1.
  • This housing has dimensions similar to those of the intermediate piece 7 in a cross-sectional plane substantially parallel to the surface of the cross member 1, so as to receive the lower face of the intermediate piece 7.
  • the edges around the periphery of the housing supported by the upper surface of the cross member 1 create various abutment surfaces against which the intermediate piece 7 rests to hold it in position on the cross member 1.
  • the various edges around the periphery of the housing and its complementary shape with the lower part of the intermediate piece 7 also facilitate the mounting of this intermediate piece 7 onto the cross member 1.
  • the shape of the orifice of the cavity 11 through the cross member 1 and the similar shape and dimensions of the orifice 71 of the intermediate piece 7 have a grooved or oblong arrangement oriented along the axis of the cross member 1.
  • This grooved or oblong arrangement then has a width slightly greater than that of the anchoring axis 3. Under these conditions, the positioning of the anchoring axis 3 through the intermediate piece 7 and the cross member 1 blocks any movement of the intermediate piece 7 relative to the cross member 1 along an axis perpendicular to the axis of the cross member 1.
  • the upper surface of the intermediate piece 7 which carries the arrangement grooved 72 is likely to be positioned level with the upper surface of the cross member 1 or, alternatively, according to a construction with a level offset, so that the surface of the intermediate piece 7 which carries the grooved arrangement 72 has a level offset with respect to the upper surface of the cross member 1.
  • the grooved arrangements 42, 72 have a sawtooth pattern.
  • This sawtooth pattern has the advantage of facilitating the positioning of a first grooved arrangement 42 against the second grooved arrangement 72.
  • the grooved arrangements 42, 72 have a crenellated arrangement.
  • the spacing between two reliefs of these grooved arrangements is at least slightly greater than the width of the corresponding reliefs. Under these conditions, the interlocking of the reliefs carried by each of the grooved arrangements 42, 72 is facilitated.
  • the anchoring pin 3 interacts with the opening 41 of the cover piece 4 and/or with the support structure 2 via an insulating sleeve 9.
  • the sleeve 9 is mounted coaxially with the opening 41 of the cover piece 9 so that the anchoring pin 3 passes through it.
  • the sleeve 9 is positioned coaxially with an opening in the support structure 2 through which the lower end of the anchoring pin 3 passes.
  • the insulating element 9 thus provides additional electrical insulation between the rail and the supporting structure 2.
  • the rail is also supported against the sleeper 1 by means of an insulating base plate.
  • electrical insulation can be provided by using, besides insulating elements 9, cover pieces 4 and/or intermediate pieces 7 made of a material selected for its electrical insulation properties.
  • the clamping mechanism 5 involves at least one nut 51 in cooperation with a threaded portion of the anchoring shaft 3. This threaded portion is thus capable of being positioned along the entire length of the anchoring shaft 3 or only at its second end 32.
  • the nut 51 of the clamping mechanism 5 is thus capable of bearing directly or indirectly against the upper surface of the cover piece 4.
  • the clamping mechanism 5 incorporates at least one spring element 52 through which the anchoring pin 3 passes and which bears, directly or indirectly, against the upper surface of the cover piece 4.
  • these spring properties can be obtained by springs or elements with elastic properties such as Belleville washers stacked along the upper part of the anchoring pin 3.
  • the adaptation mechanism 6 also includes a second grooved arrangement carried by the underside of the cover piece 4 and cooperating with the complementary grooved arrangement carried, directly or indirectly, by the upper surface of the cross member 1, the grooves of this second pair of arrangements being arranged substantially parallel to the axis of the cross member 1.
  • This particular orientation of the grooves of the second pair of arrangements thus makes it possible to adjust and lock the position of the orifice 41 of the cover piece 4 along an axis substantially perpendicular to the axis of the cross member 1.
  • the construction features that can be implemented and are applicable to this second pair of arrangements are identical to those detailed previously for the first pair of arrangements.
