Description

DESCRIPCIÓN DESCRIPTION

Rail connection flange Field of the Invention

La invención se refiere a una brida que permite la unión de los extremos de dos carriles anexos. Esta unión es temporal mientras que se realizan los trabajos previos a la soldadura 5 de los carriles para conformar la vía. The invention relates to a flange that allows the joining of the ends of two attached rails. This union is temporary while the works prior to welding 5 of the rails are carried out to form the track.

Background of the invention

En los trabajos de construcción ferroviarios se empalman tramos de carriles de longitud determinada, por ejemplo 270 m, que posteriormente son soldados. Antes de realizar la soldadura de los mismos, es necesario realizar determinado tipo de trabajo sobre la vía, 10 como por ejemplo el bateo del balasto, para lo que los tramos deben permanecer unidos mediante bridas de unión. In railway construction works, sections of rails of a certain length are spliced, for example 270 m, which are subsequently welded. Before welding them, it is necessary to perform a certain type of work on the track, 10 such as the batting of the ballast, for which the sections must remain joined by joining flanges.

Son conocidas en el estado de la técnica algunas bridas de unión, sin embargo no ofrecen una garantía de unión y estabilidad adecuadas durante la realización de los trabajos sobre la vía, especialmente durante la realización del bateo. Esto es debido a que los dispositivos 15 conocidos realizan una unión de los carriles contiguos en la zona del patín del carril, estando esta área del carril en la zona de influencia de los bates. Some connecting flanges are known in the state of the art, however they do not offer a guarantee of adequate bonding and stability during the performance of the work on the track, especially during the performance of the batting. This is because the known devices 15 make a connection of the adjacent rails in the area of the rail skate, this area of the rail being in the area of influence of the bats.

Descripción de la invención Description of the invention

La brida de unión objeto de la invención asegura estabilidad relativa entre los extremos de los carriles que están uniendo a la vez que permite realizar las operaciones de montaje de la 20 vía previas a la soldadura de los carriles superando las desventajas anteriormente descritas. The joint flange object of the invention ensures relative stability between the ends of the rails that are joining while allowing the assembly operations of the track prior to the welding of the rails to overcome the disadvantages described above.

La brida de unión para carriles objeto de la invención se caracteriza por que comprende: The connecting flange for rails object of the invention is characterized in that it comprises:

- Sendas piezas estabilizadoras cada una adaptada para estar situada longitudinalmente a ambos carriles a unir. Dichas piezas comprenden una superficie interna superior y una superficie interna inferior adaptadas para estar 25 situadas en contacto con la raíz de la cabeza y la raíz del patín de los carriles a unir. Se entiene por raíz la superficie de la cabeza y el patín contigua al alma del carril. - Two stabilizing pieces each adapted to be located longitudinally to both rails to join. Said pieces comprise an upper internal surface and a lower internal surface adapted to be in contact with the root of the head and the root of the skate of the rails to be joined. The surface of the head and the skate next to the soul of the rail are understood as root.

- Un primer y un segundo elemento de apriete cada uno situable sobre uno de los carriles a unir en contacto con la cara externa de ambas piezas estabilizadoras y 30 destinado a presionar ambas piezas estabilizadoras hacia los carriles a unir. - A first and a second clamping element each one that can be placed on one of the rails to be joined in contact with the external face of both stabilizer pieces and 30 intended to press both stabilizer pieces towards the rails to be joined.

De este modo, las piezas estabilizadoras sujetan el carril en la zona del alma, zona que no está en la zona de influencia de los trabajos de bateo. Más específicamente, la sujeción se realiza por la raíz tanto de su cabeza como de su patín de modo que logran que ambos carriles permanezcan unidos de una manera estable y sin cabeceo durante los trabajos realizados sobre la vía. 5 In this way, the stabilizer pieces hold the rail in the soul zone, an area that is not in the zone of influence of the batting works. More specifically, the fastening is carried out by the root of both your head and your skate so that both rails remain united in a stable way and without pitching during the work done on the track. 5

Descripción detallada de la invención Detailed description of the invention

En las figuras 1 y 2 se muestra un ejemplo de realización de la brida objeto de la invención, 15 más concretamente en la figura 1 se representan ambas piezas estabilizadoras (11) con su superficie interna superior (12) e inferior (13) situadas en contacto con la raíz (5) de la cabeza (2) y con la raíz de la base (6) del patín (4) de uno de los carriles (1) a unir. An embodiment example of the flange object of the invention is shown in figures 1 and 2, more specifically in figure 1 both stabilizer parts (11) with their upper (12) and lower inner surface (13) located at contact with the root (5) of the head (2) and with the root of the base (6) of the skate (4) of one of the rails (1) to be joined.

En el ejemplo de realización mostrado en la figura 1, la superficie interna superior (12) e inferior (13) de las piezas estabilizadoras (11) comprende una sección decreciente hacia el 20 alma (3) del carril (1) antagonista con la sección de la raíz de la cabeza (2) y del patín (4) de modo que las piezas estabilizadoras (11) y el carril (1) poseen una amplia superficie de contacto y además al incrementar el apriete de dichas piezas estabilizadoras (11) contra el carril (1) se aumenta el enclavamiento de las mismas (11) y dicha superficie de contacto. In the exemplary embodiment shown in Figure 1, the upper (12) and lower (13) internal surface of the stabilizer parts (11) comprise a decreasing section towards the core (3) of the rail (1) antagonistic to the section of the root of the head (2) and of the skate (4) so that the stabilizing parts (11) and the rail (1) have a wide contact surface and also by increasing the tightening of said stabilizing parts (11) against the rail (1) increases the interlocking of them (11) and said contact surface.

Se representa también las figuras 1 y 2 uno de los elementos de apriete (14) ligado por lo 25 tanto a uno de los carriles (1) a unir. El elemento de aprite (14) está en contacto con la cara externa de ambas piezas estabilizadoras (11) y presiona ambas piezas estabilizadoras (11) contra el carril (1). Más específicamente el elemento de apriete (11) está situado sobre la cara externa de ambas piezas estabilizadoras (11) a la altura del alma (3) del carril (1) en sendos recesos (18) para el alojamiento de sendos resaltes (19) del elemento de apriete 30 (14). Figures 1 and 2 are also shown one of the clamping elements (14) linked therefore to one of the rails (1) to be joined. The clamping element (14) is in contact with the outer face of both stabilizer parts (11) and presses both stabilizer parts (11) against the rail (1). More specifically, the clamping element (11) is located on the outer face of both stabilizer parts (11) at the height of the core (3) of the rail (1) in two recesses (18) for the accommodation of two projections (19) of the clamping element 30 (14).

El elemento de apriete (14) comprende una prolongación que abraza el patín (4) del carril (1) y que por lo tanto rodea al mismo (4). Alternativamente el elemento de apriete (14) podría tener una prolongación que abrazara la cabeza (2) del carril (1). The clamping element (14) comprises an extension that hugs the skate (4) of the rail (1) and therefore surrounds it (4). Alternatively, the clamping element (14) could have an extension that would hug the head (2) of the rail (1).

En el ejemplo de realización mostrado en las figuras el elemento de apriete (14) comprende sendas piezas simétricas (15, 16), cada una de ellas en contacto con una de las piezas 5 estabilizadoras (11) y por lo tanto presionando la misma (11) sobre el carril (1). Para la unión de ambas piezas simétricas (15, 16) se dispone de un tornillo de apriete (17) que en el ejemplo de realización mostrado atraviesa ambas piezas simétricas (15, 16) por la parte inferior del patín (4) del carril (1). In the exemplary embodiment shown in the figures, the clamping element (14) comprises symmetrical parts (15, 16), each in contact with one of the stabilizing parts 5 (11) and therefore pressing it ( 11) on the rail (1). For the connection of both symmetrical parts (15, 16) there is a clamping screw (17) which, in the example of embodiment shown, crosses both symmetrical parts (15, 16) through the bottom of the rail (4) of the rail ( one).
