Definitions

  • the present invention relates to a recoverable temporary traverse applicable in the construction of railway tracks consisting of plates with rails that are not interconnected, and that are anchored by means of block or plate supports with inserts.
  • the rails are held by fixing means that are part of block-shaped supports or plates with inserts that are independent for each rail, which are anchored in place by a setting concrete slab where they are embedded and that holds them when the concrete is set, so in this type of railway it is the setting concrete slab, when hardened, what determines the track gauge, the inclination of the rails, and their position in the space, so that the track and their fittings must be perfectly mounted and positioned before pouring the concrete that will form the slab.
  • a concrete base is firstly poured, on which, once set, the track is assembled by using temporary traverses that are placed every 1.5 to 2 metres away and which are responsible for maintaining the track gauge and the inclination of the rails with respect to the running surface.
  • the track is lifted by jacks, the block supports or plates with insert are hanged to the rails and topographers position the track in that space by making all the necessary corrections.
  • the track is perfectly aligned and levelled, it is maintained in position by means of shims placed under the rails or the supports, or using threaded levelling rods incorporated to the temporary traverses and that maintain the track in place while the concrete, which will form the setting slab, is poured. Once it has / set, the temporary traverses are removed.
  • topographic carts used for the track positioning which were created afterwards and that are cars with three support points equipped with rollers that allow for its circulation by the track by taking data along the entire path instead on a point to point basis as it was previously done. This enables topographers to do their job quickly and accurately.
  • the reduced space between the rail foot and the setting slab raise serious challenges, because if the temporary traverses are built in a single piece, then it is necessary to loosen all the rail fixing means in order to lift them and remove the traverses with the aim of recovering them; on the other hand, if they are built divided so they can be removed without having to raise the track just assembled, then they lose stiffness and precision.
  • the attachment of the rails at the rail foot which is the farthest part from the running surface and the active side of the rail, which is where the track parameters must apply, causes the occurrence of deformations that affect the slope of the track and the track gauge, thus complicating the topographer's work and reducing the accuracy of the track.
  • the recoverable temporary traverse of the present invention is characterized in that it comprises a main supporting structure to be placed on the inside of the track between the rails, perpendicularly to the axis thereof, and intended to set the track gauge, the inclination of the rails with respect to the running surface and to maintain the rails and stands in the proper position while the setting concrete, which forms the slab, hardens, and at least one pair of secondary elements to be placed from each of the outer faces of the track by passing beneath the rails in order to be temporarily attached to the main structure and intended to press the rails against the main structure by fixing them to it, thus ensuring their correct position.
  • the main supporting structure is formed by at least one piece where their vertices form a rectangle perpendicularly oriented to the ground, and in the two upper corners of which are angular shaped housings in which a portion of the inner lower corners of the rail head is inserted and supported, and in the two lower corners of which are other angular shaped housings in which a portion of the inner upper corners of the rail foot is inserted and supported.
  • this main structure has two main anchoring systems located at its bottom and intended for the temporary attachment of the secondary parts.
  • This main structure may also have at least two mechanisms for regulating the height of the structure with respect to the concrete base on which the track is assembled.
  • This arrangement allows for the rails to rest against the main structure at two points, one located at the rail head just below the point where the track gauge is measured thus ensuring this, the other located at the corner of the rail foot, that is, the point situated on the same side of the farthest rail from the previous one and therefore ensuring as greater accurately as possible in the inclination angle of the rails. Furthermore, as the rail is engaged by the upper and lower housings of the main structure, it is impossible that a vertical sliding occurs between the main structure and the track in case the track were maintained in an elevated position through temporary traverses provided with mechanism for adjusting the height of the structure.
  • This arrangement also allows for the main support structure to be extracted from the recently assembled track by turning and rotating it, thus making unnecessary to remove any element in the track to facilitate the removal thereof and decreasing the work, increasing the accuracy of the track parameters, while allowing, if desired, the main structure for being made in a single piece, what eliminates potential errors in manufacturing and in the assembly of the joints, increasing the accuracy of the track and making cheaper the manufacture of both, the temporary traverse and the track.
  • the supporting substructure of the height adjusting mechanisms has been provided with at least one sliding mechanism of the main supporting structure and at least a mechanism for adjusting and fixing the position thereof on the substructure.
  • Secondary angle parts whose wings form an angle of about 90 degrees are also provided. These pieces have, at the end of the lower wing, an anchoring element which allows to temporarily fixing them to the anchors provided for this purpose on the main frame passing beneath the rail through the space existing between the setting concrete and the bottom face of the rail foot. They also have, at the end of the vertical wing, a tightening mechanism intended to push the rail from the outside of the track by supporting it at its ends against the housings of the main structure. Furthermore, this wing includes at least one projection, situated under the tightening mechanism and intended to rest on the upper and outer face of the rail foot and to prevent the secondary part from sliding from the anchoring element of the main structure because of the pressure mechanism action on the rail by pushing it against the main structure.
  • This arrangement allows to attach the rails to the main support structure in a solid and accurate way as it allows for the rails to be pressured against the angular housings of the main supporting structure, but without interfering in any way with the running surface, thereby enabling the use of topography carts, what facilitates the work of topographers and increases the accuracy of the track parameters. Additionally, as they are separate pieces that can be easily assembled and disassembled, they allow the main structure to be extracted from the recently assembled track by turning and rotating it without the need to disassemble any of its parts.
  • the recoverable temporary traverse comprises: a main supporting structure (1), secondary pieces (2) intended to hook onto the opposite ends of the main structure (1) and a tightening mechanism (10), made of screws mounted on said secondary parts and laterally pushing the rails (12) of the track against the opposite ends of the main structure by establishing a fixed separation and inclination of said rails (12).
  • the main supporting structure (1) located on the inside of the track between the rails (12) is intended to maintain the track gauge and inclination of the rails (12) while the setting concrete (21), which will definitely attach the track to said concrete base (22), hardens.
  • the main supporting structure (1) is formed by a flattened piece, in this case, a cast piece, perpendicularly oriented to the ground and having, at its opposite ends, upper housings (3), of angular shape, into which a portion of the inner lower corners of the heads (13) of the rails (12) are inserted and supported, and other lower housings (4), of angular shape, into which a portion of the inner upper corners of the foot (14) of the rails (12) are inserted and supported.
  • this main structure (1) has two hook-shaped anchoring systems (5) located at its bottom and intended for the temporary attachment of the secondary parts (2).
  • This main structure (1) also have two height adjusting mechanisms (6) for adjusting the height of the structure with respect to the concrete base (22) on which the track is mounted.
  • the secondary parts (2) have two wings (7, 9) which, in the example shown, form an angle of about 90 degrees.
  • These secondary parts (2) have, at the end of the lower wing (7), a housing (8) which allows to temporarily attach them to the hook-like anchoring elements (5) of the main structure (1); said lower wings (7) passing beneath the rails (12) without interfering in the running surface (23).
  • Said secondary parts (2) also have, at the end of the wing vertically located (9), a tightening mechanism (10), represented in this case by a screw, intended to push the rail (12) from the outside of the track by supporting it at its ends against the housings (3, 4) of the main structure (1).
  • a tightening mechanism (10) represented in this case by a screw, intended to push the rail (12) from the outside of the track by supporting it at its ends against the housings (3, 4) of the main structure (1).
  • this vertically positioned wing (9) includes a projection (11) intended to rest on the upper and outer face of the rail foot (14) and prevent that the secondary piece (2) swing from the anchoring element (5) of the main structure (1) upon actuation of the tightening mechanism (10) on the rail (12) when pushing it against the main structure (1).
  • Figures 5 and 6 represent a schematic elevation ( Fig. 5 ) and plan ( Fig. 6 ) view of the turning (15) and rotation (16) movements to be performed by the traverse of the invention in order to be removed from the rails once its task has finished, in case its main supporting structure (1) is made in a single piece without detachable joints.
  • the height adjusting mechanisms (6) can have different configurations.
  • said height adjusting mechanisms (6) are constituted by threaded rods mounted on two drilled and threaded housings that vertically pass through the axis of the main structure (1), so that they allow for the regulation of the height of the main structure and of the track on the concrete base (22).
  • the height adjusting mechanisms (6) are integrated in a substructure (17) situated between the rails and independent from the main supporting structure (1). These height adjusting means allow for keeping the rails (12) and their supporting elements (20) elevated and in position on the concrete base (22) while the setting concrete (21), which is intended to definitely attach the track, hardens.
  • This substructure (17) also incorporates sliding mechanisms (18) and a position locking mechanism (19) allowing the cross movement of the main supporting structure (1) and of the track, thus facilitating the alignment of the latter.
  • the sliding mechanism in the cross direction and the locking mechanism of the substructure (17), which has the height adjusting mechanism are constituted by an adjustable tensioner (24) that is attached at one of its ends to said substructure (17) and at its opposite end to the main structure (1).
  • the vertical wing (9) does not have the projection intended to rest on the upper and outer surface of the rail foot (14), having, however, the lower wing (7) of each of the secondary parts (2) two housings (8) for being hooked onto the respective pairs of anchoring elements (5) defined at the lower areas of the respective ends of the main structure.
  • This double anchor prevents the swinging of the secondary parts (2) with respect to the main structure (1) during the pushing of the rails (12) against said main structure by means of the tightening mechanisms (10).
