    SEAT PLATE DEVICE FOR RAILWAY RAIL
    DESCRIPTION
    The present invention relates to a seat plate apparatus for rail tracks.
    The rail rail seat plates are used in railroad tie-down assemblies to provide a rail support region, to support a rail rail on a rail foundation, such as a concrete slab. The anchoring devices, which may be integrally formed with the other parts of the seat plate or be removably attached thereto (by bolts or other means), are provided on opposite sides of the rail seat region to retain the respective elastic rail fasteners of the rail with which the rail can be fixed to the foundation of the rail.
    Conventionally, such seat plates are made of metal, for example rolled steel or cast iron, but for the purpose of reducing the weight and / or cost it may be desirable that the seat plate is made at least partially of plastic material, such as glass reinforced nylon.
    However, elastic rail tie clips apply a lot of force on the anchoring devices on which they rest, when the clips are being installed and / or when the clips are resting on the rail. If used with a plastic seat plate, the forces to which the anchoring device is subjected through the clip would damage the anchoring device (if it is plastic) and / or the area of the seating plate around the anchoring device
    For example, consider a plastic seat plate that has metal anchoring devices (protrusions) that house rail tie clips known as e-clips® PANDROL that are operated on the rail of a rail in a direction parallel to the longitudinal axis of the rail. Such staples are formed by bending a metal rod in order to have at one end a straight portion, which acts as a central pin for its location within an opening in a projection fixed to the foundation of the rail adjacent to the rail seat, and folded portions , on both sides of the straight portion, which have contact regions to support respectively on the rail skate (the "finger" of the staple) and part of the projection (the "heel" of the staple). As such, a clip is actuated inside the projection, the positions of the contact forces in the heel and the central pin of the clip in relation to the edge of the rail remain the same, but the loads increase as the clip is pushed more inside the housing, deflecting more and generating more load. The load on the staple finger acts on the rail instead of the anchoring device, such that there is a moment that acts on the anchoring device immediately from the point when the staple drive is started on the anchoring device. . That is, as seen along the axis line of the rail, in each staple position there is a large upward force that acts on the central pin of the staple and a large downward force that acts on the heel of the staple. Together, these four charges apply two large "negative bending" moments to the seat plate on each side of the rail. Plastic is a relatively weak material with a relatively low elastic modulus, such that unless the plate is sufficiently deep to offer sufficient resistance to bending it will bend upward under these forces.
    With another type of rail tie clip (such as the type known as for example PANDROL FASTCLIP®), which is operated on a rail skate, laterally, that is,

    perpendicularly with respect to the longitudinal axis of the rail, since at the beginning all the contact positions of the clip act against the anchoring device, initially there is no net moment acting on the anchoring device. However, when the staple finger moves through the anchoring device on the rail, the forces on the anchoring device are no longer balanced and a large negative bending moment suddenly acting around an axis parallel to the axis is applied. of the rail on the seat plate.
    It is desirable to provide the rail rail seat plate apparatus in which the seat plate is made of plastic material and the seat plate can be prevented from being damaged.
    In accordance with an embodiment of a first aspect of the present invention, a rail rail seat plate apparatus is provided configured to provide a rail support region, to support a rail rail on a rail foundation and two anchoring devices, located on opposite sides of the rail support region, to retain the respective elastic rail fastening clips with which the rail rail can be fixed to the foundation of the rail, whose rail seat rail plate apparatus comprises a plate , at least partially made of plastic material and configured to provide the rail support region and first and second metal parts each comprising a first staple coupling portion of the rail rail, a second stapling portion of the rail rail staple , and an elongated portion connecting the first staple coupling portion from rail rail to the second rail rail clip coupling portion, wherein the elongated portions of the metal parts extend under the seat region of the plate rail, the first rail rail clip coupling portion of the first metal part and the second rail rail staple coupling portion of the second metal portion extends upwardly through the plate on one side of the plate rail seating region, and the second staple coupling portion of Rail rail of the first metal part and the first rail rail clip coupling portion of the second metal part extends upwardly through the plate on the opposite side of the seat region of the plate rail, such that a first of the two anchoring devices is formed by the first rail rail staple coupling portion of the first part and metal and the second rail rail staple coupling portion of the second metal portion and a second of the two anchoring devices is formed by the rail rail staple coupling portion of the first metal portion and the first coupling portion of rail rail staple of the second metal part.
    By forming the two anchoring devices as two halves joined together under the rail, such that the anchoring device of the outer face (side facing the field) of the plate is connected to the anchoring device of the inner face of the plate, all the moments are contained within the metal parts and do not act on the plastic plate, thus preventing the plate from being damaged.

    Optionally, according to the described embodiment, the metallic components 120A, 120B are identical to each other, which has the advantage that it is not necessary to differentiate the two metallic components 120A, 120B except for the way in which they are oriented on plate 10, thus simplifying the development and use of the apparatus, but this is not essential.
    A railroad tie-down assembly that includes a railroad seat plate 1 'apparatus according to a second embodiment of the present invention is shown in Figure 6. The same reference numerals are used with respect to Figures 1 to 5 except for the parts of the apparatus that differ but serve the same purpose as those of the apparatus 1 of the seat plate, these are assigned the same reference numerals followed by ', for example, 120A'. The apparatus 1 'of the rail rail seat plate is configured to provide a rail support region 11, to support the rail rail 2 on a rail foundation 100, and two anchoring devices 12A', 12B ', located, on opposite sides of the rail support region 11, to retain the respective elastic rail fasteners 3A, 3B, with which the rail 2 can be fixed to the rail foundation 100. In this embodiment the seat plate apparatus 1 ’is symmetrical in plan around the center line of the rail support region 11 which extends perpendicularly to the longitudinal axis of the rail.
    The apparatus 1 'of the rail rail seat plate comprises a plate 10' (as shown in Figure 7), made at least partially of plastic material, which is configured to provide the rail support region 11, and first and second metal rail mooring parts which in this embodiment consist of the metallic components 120A '(as shown in Figure 8), 120B' which are separated from each other. In this embodiment the metallic components 120A ’, 120B’ are designed to extend along substantially the entire length of the plastic plate 10 ’. Each metallic component 120A ', 120B', which is made for example of cast iron, comprises a first rail rail staple coupling portion 121 'having a lower connection portion 125', a second staple coupling portion 122 ' of rail rail having a lower connecting portion 124 ', an elongated portion 123' connecting the first rail fastener coupling portion 121 'to the second rail rail stapling coupling portion 122' in the respective portions 124 ', 125' of respective lower connection thereof, first and second end portions 128 ', 129' extending from respective portions 125 ', 124' of lower connection, and first and second portions 126 ', 127' of return projecting outwardly from one side of the metallic component 120A ', 120B' in the respective end portions 128 ', 129', and having scas 126A ’, 127A’ of respective screws.

    which runs between wall 121C ’and wall 122C’.
    In the described embodiments, the rail tie clips 3A, 3B to be retained, are of the type known as PANDROL FASTCLIP® which, as described for example in EP0619852, are designed to engage and disengage from the skate of a lane, laterally with respect to the longitudinal axis of the rail. However, the rail rail seat plate apparatus of an embodiment of the present invention could be designed for use with other types of elastic rail tie clips, such as other lateral drive clips (eg clips of the known type such as SAFELOK®, made of plate-shaped material, of which an example is described in US6923381).
    When the rail tie clips to be retained are not the PANDROL FASTCLIP® rail ties, the shape and configuration of the first and second portions 121, 122 (121 ', 122') of rail rail clip coupling and / or its staple coupling surface 121A, 122A (121A ', 122A') will be adapted accordingly and therefore likely to differ from those shown in the present application. Similarly, plate 10 (10 ’) can be adapted for use with other types of rail ties. For example, ramps 135A, 135B (135A ’, 135B’ and / or 136A ’, 136B’) can be dispensed with if they are not necessary.
    In the embodiments of the present invention the first and second rail 12A, 12B, (12A ’, 12B’) rail anchor devices consist of a set of two separate metal components 120A, 120B (120A ’, 120B’). The first rail rail anchoring device 12A (12A ') consists of the first rail rail staple coupling portion 121 (121') of the first 120A (120A '; 120A' ') of the metal components and the second portion 122 (122 ') of rail rail staple coupling of the second 120B (120B') of the second metal components, and the second rail rail anchoring device 12B (12B ') consists of the second portion 122 (122') of rail rail staple coupling of the first metallic component 120A (120A ') and in the first rail rail staple coupling portion 121 (121') of the second metallic component 120B (120B ').
    Although in the embodiments shown in the accompanying drawings and described above, the metal components 120A, 120B (120A ', 120B') of each apparatus 1 (1 ') are separated from each other, in some circumstances it may be advantageous, with a view to improving resistance against forces and additionally protecting the plate from excessive load, if the metal components 120A, 120B (120A ', 120B') are linked by one or more additional parts (not shown in the drawings), for example, a bar of material attached to and extending between a first staple coupling portion of a first metal part and a second staple coupling portion of a second metallic part, and / or a bar of material attached to and which is extends between a first staple coupling portion of the second metal part and a second staple coupling portion of the first metal part. It should be noted that in the described embodiments the metallic components 120A, 120B (120A ’, 120B’) do not have any threaded portions.
    As mentioned earlier, metal plate 10 (10 ’) and metal components 120A, 120B (120A’, 120B ’) can be configured to achieve a tight fit between them. In this case, as shown in Figure 5 with respect to the first embodiment, in order to connect one of the metal components 120B (120B ') to the plate 10 (10'), the first and second 5 portions 121, 122 (121 ', 122') of staple coupling of the metallic component 120B (120B ') are aligned below the plate 10 (10') with the respective openings 131, 133 (131 ', 133') thereof and they are then inserted into openings 131, 133 (131 ', 133') until the first and second portions 121, 122 (121 ', 122') of staple coupling extend outwardly from the upper side of the plate 10 (10 ') and the elongated portion 123 (123') has slipped into place within the elongated recesses 10B (10B '). This can be done before, after (as in Figure 5) or at the same time as the connection of the other metallic components 120A (120A ’) to the plate 10 (10’). The components 120A, 120B (120A ', 120B') are retained within the plate by, for example, some form of pressure adjustment coupling of the plate with the components and / or the presence of the clips when they are in contact. with the first and second portions 121, 122 (121 ', 122') of rail clip coupling in a position (pre-installed) "parked" or installed.
    In the described embodiments, the plate thickness 10 (10 ') varies from one end region 14 (14') to another end region 14 (14 '), such that generally the part of the plate 10 (10' ) on one side of the rail support region 11 is thicker than the part of the plate 20 10 (10) on the other side of the rail support region 11, so that the support region 11
    Rail is inclined in order to cant rail. This is not essential, however; for example, the rail cant could be provided in some other way, for example by placing a wedge under the plate 10 (10 ’) or by tilting the top surface of the rail foundation.
