Definitions

  • the present invention refers to improvements introduced in the elbowed plates for elastic fastenings of rails on concrete ties, with which notable advantageous characteristics are offered, both for the optimization of the injection process of the constitutive plastic material, and for increasing the strength capacity of the plates versus the stresses to which they are subjected to.
  • the object of the invention contitutes the substantial cost reduction of each one of the parts.
  • elbowed plates on which the improvements which are the object of the invention are applied constitute the five most used versions from among those which make up the classical elastic fastenings used by RENFE (with type Skl1 clip) for the various models of concrete ties.
  • the parts which define the elbowed plates are placed on the rail seats, arranged to such effect on the tie, with the external and internal confronted at both sides of the rail shoe. On each one of them abuts the elastic clip, attached by means of the corresponding screw which crossed the plate to be tied down to the tie, and which achieves the correct fastening of the rail on said tie when the nominal torque is applied.
  • the improvements introduced in this type of elbowed plates are based, together with changes in the geometry of the part in order to obtain a greater seating of the clip, on the reduction of the quantity of material by means of the introduction of longitudinal webs, transversal to the shoe of the rail, which, together with a reduction in the weight, allows the obtention of greater strength against the real requirements of the parts during their running on the track.
  • the ties are of prestressed monoblock concrete (prestressed or post-stressed), participating in the assembly for a single width of track, or for double width (versatile tie).
  • elbowed plates are those fastening elements which transmit the vertical loads of the clip to the tie, as well as those which support the lateral thrust of the rail shoe, produced by the stress of the wheels of the trains. Therefore, its mission, besides serving as lateral buffer, is double: support of the lateral and vertical loads caused by the running of the railroad and acting, together with the clip and the screw, as fastening element of the rail to the monoblock tie.
  • the tie includes a transversal or rail seat recess which defines a housing permitting the perfect coupling of the elbowed plates and consequently that of the rest of the elements.
  • elbowed plastic plates used in the elastic fastening of rails and which are the object of RENFE Technical Specification 03.360.566.8, form part of an elastic system, designed for the replacement of the previous metallic part, with which the monoblock ties were originally equipped with, such as is described in the standard in force (N.R.V.3-2-2-0).
  • the rail has to bear dynamic stresses during the passing of the trains, vertical ones produced by the loads transmitted by the rim of the wheels and other lateral ones, caused by the flange of the wheels when they impinge on the active face of the rail head, during the guiding of the circulation and in the correction of the detrimental movements.
  • the lateral stresses are produced singularly in the "opening" direction of the track, that is to say, with a tendency to separate the rails. To achieve this, they must be absorbed by the attachment system, and particularly by the elbowed part which fastens the wing of the exterior shoe to the track box, since in any other case, that is to say, if it should be displaced outwards from the rail, an excessive over-width would be produced.
  • a system is looked for, which, by means of an increase of rigidity in the parts, makes them more resistant to these lateral stresses.
  • Exterior elbowed plates (rail versions UIC 54 and UIC 60).
  • the modification in the design of these parts is more reduced than the one carried out on its interior pairs on versatile ties, due to the fact that they must directly bear the stresses transmitted by the rail during the passage of the moving material, fundamentally, the lateral load, besides the vertical compression stress conferred by the torque of the clip on its rear side, though this be comparatively very inferior.
  • Guide elbow plates are the ones used in the assembly on the concrete tie of one single width of track. With the object of maintaining a functionality criteria and to facilitate the assembly on track of these plates, a single design has been made for the two positions on the tie. Consequently, variations of the geometry have been adopted, sized to resist the loads which may be produced in the most unfavourable position, which is the exterior position.
  • drawing sheets are enclosed, which include figures in which, with illustrative and non limitative character, the following has been represented.
  • Figure 1 is a longitudinal side elevational view, with sectioned quadrant, of an elastic fastening of rails on concrete ties, by means of conventional elbowed plates. It also corresponds to the section on the cut line A-A of figure 2.

  • Reference 7 designates the seating plate on which rail 1 on tie 2 directly lies. Screw 6 remains duly tied down to tie 2, whcn the same includes threaded spigots 8.
  • the elbowed plates 3 are equipped with an inferior projection 9 which meshes in housing 10 provided in tie 2.
  • elbowed plates which have been referenced with number 3, offer the conventional design of eminently solid elbowed plates, which have been modified in the manner which shall be subsequently seen in order to achieve the improvements recommended according to the invention.
  • Figures 3 through 6 represent one of the versions of conventional elbowed plates, specifically, the one intended to remain situated in the interior part of rail UIC-54 for versatile tie (double width track).
  • Figures 7 and 11 show the improvements introduced in this version of plates, according to the invention, with the existance of a parallel correspondence with the different views and sections of one and the other of the elbowed plates, with the exception, that in the elbowed plate which includes the improvements which are the object of the invention, the inferior plan view has been added in order to observe the arrangement of the transversal webs according to figure 11.
  • the central hole 11 is reinforced with a circular web, also 4 mm thick, with the exception of the buffer zone against shoe 4, in which, in order to keep the 2 mm resinking provided for the preassembly of the seating plate 7, said web has to be of 3 mm in this embodiment example shown in the figures.
  • This circular web is referenced with number 16.
  • the thickness of plate 13 in the zone directly confronting the rail shoe is also of 4 mm, as well as the webs 14, keeping constant in the rear section of the part.
  • the transversal webs 14 and 15 may directly receive some lateral load, less than in the exterior parts, on its upper 2 mm as shall be subsequently seen.
  • Buffer 17, or front and rethickened part of the elbowed plate 13 has a width of 15,4 mm in this version for rail UIC-54 and is provided with a 60o chamfer 18.
  • Circular web 16 reinforces the central hole 11 and maintains a continuity in the transmission of stresses from the four central webs 15 and 14.
  • the rear support zone of the elastic clip 5, referenced with number 19 is the lightest, since the maximum thickness of 21 mm of the solid part 12, is avoided. It is considered that this lightening perfectly supports the vertical load, between 500 and 750 kg at each support point of the elastic clip 5, produced by the torque of the same.
  • the basic size of buffer 17 may be increased in the parts for rail UIC-54, which is 12,4 mm, up to 2,5 mm or 5 mm, to permit a stepped aperture of track jointly with the exterior part (which shall be mentioned further on), every 2,5 mm, until 10 m have been reached.
  • part 21 for rail UIC-60 admits an increase of 2,5 mm in its basic size, 9 mm, to permit a stepped aperture of track jointly with the exterior part, every 2,5 mm up to 5 mm.
  • the arrangement of the six webs is radial, whilst that of the four central webs is perpendicular to shoe 4.
  • the oblique webs are referenced with number 24 and the transversal ones to the plate, with number 25.
  • the webs have a constant thickness of 6 mm, with the exception of the two end ones, which due to geometric reasons, is of 5,5 mm. Consequently, the thickness of the gaps is variable.
  • the thickness of the plate confronted directly to the rail shoe is also 6 mm, as are the webs.
  • the circular web on the contrary to the interior plates 13, reinforces the central hole 11 in its front zone, transmitting the stresses through the webs which border the same.
  • the rear support zone of the elastic clip 5 is lightened in order to overcome the present strong thicknesses, being designed with a constant thickness.
  • zone 26, where this support begins has a greater thickness than in the interior ones, in order to resist the greater alternative compression and tensile stresses which are produced in this zone when the trains pass.
  • the rear support part in the tie has been lightened by 3,5 mm.
  • Buffer 29' on the part for rail UIC-60 has a width of 12 mm, which is compatible with the 18,6 mm width in the version for rail UIC-54 (see figure 18).
  • These plates 23 and 28 having additionally, the same 60o angle of chamfer 18 of heel 29 and 29'.
  • the basic size of buffer 29 in parts 23 for rail UIC-54 can be reduced, from 15,6 mm to 2,5 or 5 mm, to allow a stepped aperture of track jointly with the interior part, every 2,5 mm, until the 10 mm has been reached.
  • part 28 for rail UIC-60 admits a 2,5 mm reduction in its basic size, 9 mm, to permit a stepped aperture of track jointly with the interior part, every 2,5 mm up to the 5 mm.
  • the guide elbowed plated 31 has a rectangular contour and is distinguished at first sight from the upper part by a cylindrical mark 32 of 3 mm depth and 10 mm width, which is situated in buffer 33, centered with the hole 11.
  • the exterior part In the same manner as for the exterior part, it has a resistant zone 6 mm thick, the same as eight of the ten transversal webs 34 and 35 (the two ends are 5,5 mm thick due to reasons of geometry), of which the eight end ones are continuous and the two central ones discontinuous. For the same reason as the exterior part, the rear part, confronted to hole 11, has been lightened.
  • Zone 26 where the rear support of clip 5 commences, has a greater thickness in order to resist the superior, alternative, compression and tensile stresses which, when the trains pass, are produced in this area. Similarly, in order to unify the thickness, the rear support part on the tie has been lightened 3 mm.
  • the basic size of the buffer 12 mm, may be reduced or incremented into 2,5 or 5 mm, to permit a stepped aperture of track every 2,5 mm up to 10 mm.
  • the injection rate is notably increased, which produces an incremase in the production and the productive capacity.
  • the thickness of the webs has been reduced, passing from 6 mm to 5 mm, whilst keeping the same quantity of the same.
  • the injection process is simplified, obtaining improved results in their mecanical service and in the productivity of the manufacturing.
  • a transversal web is added at 10 mm of the rear clip supports, reinforcing the part and sensibly reducing the stresses supported by the part on the rear section.
  • the front section of the part has also been modified on the clip support and adjacent area, lightening the material on a non service zone.
