    DEVICE CHECK DEVICES ON RAILWAYS
    D E S C R I P C I Ó N
    OBJECT OF THE INVENTION
    The present invention relates to a device for checking fasteners on railway tracks. Specifically, it refers to checking the positioning of elastic track fasteners.
    BACKGROUND OF THE INVENTION
    In the railway field, sleepers or sleepers are the elements that are transverse to the axis of the track that serve to keep the two lanes (rails) that make up the track, as well as keep them together at a fixed distance (gauge or gauge). attached to the ballast, transmitting the weight of the rolling stock to the ballast and, through it, to the ground. They also fulfill the function of giving weight to the whole, so that the initial geometry of the path is maintained to the greatest extent possible. They are made of various materials, including wood, iron and concrete. Concrete sleepers can be monobloc or block; The former are formed by a single piece of reinforced concrete, while the naughty bibloque consists of two pieces of concrete joined by an iron bar (also known as a brace).
    In some cases, it is advisable to use elastic clip fasteners, said elastic fastening is usually made by a steel bar, of high elasticity and circular section, folded in such a way that its deformation in the mounting of the fastener provides a elastic force This piece is called "clip", to which the support is added. This clamp does not require regulation, always maintaining the same tightening.
    The form of folding of the elastic fasteners is that which ensures that sufficient force is made between the blocks and the sleepers to keep the pieces in a suitable position. Consequently, during track maintenance it should be verified that the

    Position of the fasteners is adequate and that they have not been deformed and meet the predefined characteristics for their operation.
    At present, said verification is carried out manually, that is, an operator moves along the track making measurements using, for example, a caliber or sliding bevel. Said measurement has the problem that the operator's position is not ergonomic and the repetitive measurement of the fasteners can cause a lack of attention and can lead to errors. Additionally, measurements usually take a long time due to the required accuracy.
    DESCRIPTION OF THE INVENTION
    It is an objective of the present invention to disclose a device for checking elastic fasteners on railway tracks that allows solving the problems of current measurements.
    Specifically, the present invention discloses a device for checking elastic fasteners on railway tracks comprising a template, said template having a stepped cut in which at least one reference step is defined intended to come into contact with a part of the elastic fastener in a first section and a second step intended to be in contact with a second section of the elastic part or with a reference element.
    In one embodiment of the present invention, the elastic fastener comprises at least one loop and one nose and, consequently, the testing device has a first step which is intended to come into contact with the nose and with one of the loops.
    In another exemplary embodiment, the fastener comprises two loops and the template comprises a third step so that the second step is intended to come into contact with one of the loops and the third step is intended to come into contact with the other loop. .
    The template is preferably made of a metallic material and may comprise a pair of side pins intended to come into contact with a railway track cross member or a

    elastic fastening of the railway track.
    It is important to note that by means of the device of the present invention it can be easily determined when the elastic support requires maintenance. In particular, if the fastener is located in such a way that it does not allow the contact of all the steps of the device with the respective parts of the template, it is determined that the fastener requires maintenance.
    DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:
    Figure 1 shows a perspective view of a track with an elastic fastener that can be measured by using a device according to the present invention.
    Figure 2 shows an example of elastic support.
    Figure 3 shows a device for measuring an elastic one-way clamp according to an example of the present invention.
    Figure 4 shows a device according to the present invention used for measuring an elastic fastener on a railway track.
    PREFERRED EMBODIMENT OF THE INVENTION
    One of the critical elements in terms of safety and comfort on a railway track is the fastening of the rail to the crossbar. As can be seen in figure 1, the rail 4 is arranged on the crossbar 3, said crossbar comprising a screwdriver 2 which, in turn, has a
    5
    10
    fifteen
    twenty

    30
    stop 21 at a certain height with respect to the crossbar 3. The rail 4 has a transverse projection 41 and, adjacent to said transverse projection 41, an elastic seat plate 31 is provided. The connection between the rail 4 and the crossbar 3 is it is made through the provision of an elastic fastener 1 that is disposed between the top of the screw 21 and the elastic seat plate 31.
    The elastic fasteners 1 have a clip shape with at least one fold that defines a maximum height, a minimum height and a ramp that interconnects the points of maximum height and minimum height.
    Figure 2 shows an example of elastic fastener 1 in which the fold consists of the arrangement of a first loop 10 intended to be in contact with the elastic seat plate 31, a second loop 12 also intended to be in contact with the plate with an elastic seat but at a different point and a nose 11, said nose being the one that is intended to come into contact with the stop 21 of the bolt 2. Since the elastic fastener material has elastic properties, when sliding the nose by pressure Under a screw 2, an elastic deformation of the nose downwards is performed, whereby the piece exerts a clamping force between the screw and the joint between the transverse projection 41 of the rail 4 and the elastic seat plate 31.
    The device is usually installed by sliding the elastic support under the top of the screwdriver so that the screwdriver initially allows the elastic part to pass with less height, that is, the loops and when sliding The clamping progressively performs an elastic deformation of the clamp.
    As mentioned above, it is important to make periodic measurements of each of the elastic fasteners 1 that are in the tracks to verify that the pieces are making an adequate tightening force, that is, verify that the fasteners are deformed. Enough to exert adequate force.
    For this purpose, the measuring device of Figure 3 comprises a template 5, preferably metal, which has a stepped cut at one of its ends
    longitudinally providing said stepped cut of a pair of lateral steps 50, 52 a
    5
    a first height h and a central step 51 at a second height H. Alternatively, the measuring device may have a handle to improve the ergonomics of the measurements.
    5 The mode of operation of the measuring device of Figure 3 can be observed in greater detail in reference to Figure 4. In this figure it is observed that the lateral steps 50, 52 are located in the loops and the central step is located above the nose of the restraint. In this way it is measured how deformed the elastic part is by a relative measurement between two of its sections, in this case, between a certain point of the loops 10 and the nose. Alternatively, this measurement could be performed between the ends of the loop and the nose or between external elements, such as the lateral projection of the rail and the nose.
