Fijación elástica con ajuste de posición aplicable en vías ferroviarias.Elastic fixation with position adjustment applicable on railway tracks.

Objeto de la invenciónObject of the invention

La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a una fijación elástica con ajuste de posición aplicable en vías ferroviarias, aportando a la función a que se destina varias ventajas y características de novedad, que se describirán en detalle más adelante, que suponen una mejora frente a los sistemas actualmente conocidos en el estado de la técnica para el mismo fin.The invention, as expressed in the statement of The present specification refers to an elastic fixation with position adjustment applicable on railway tracks, contributing to the function to which several advantages and characteristics of Novelty, which will be described in detail below, which represent a improvement compared to the systems currently known in the state of The technique for the same purpose.

Más en particular, el objeto de la invención se centra en un conjunto de fijación, especialmente aplicable en las vías ferroviarias, concretamente las de alta elasticidad, del tipo que se utiliza para conseguir una fijación elástica entre el carril y la plataforma, al cual se ha incorporado una serie de elementos adicionales que mejoran sustancialmente el comportamiento de la misma al paso de las circulaciones alargando su vida útil y asegurando el sistema.More particularly, the object of the invention is focuses on a set of fixation, especially applicable in railway tracks, specifically those of high elasticity, of the type which is used to achieve an elastic fixation between the rail and the platform, to which a series of elements has been incorporated additional that substantially improve the behavior of the same to the passage of the circulation extending its useful life and Securing the system

Campo de aplicación de la invenciónField of application of the invention

El campo de aplicación de la presente invención se enmarca dentro del sector técnico de la construcción de vías férreas.The field of application of the present invention It is part of the technical sector of road construction railways

Antecedentes de la invenciónBackground of the invention

Como es sabido, en las vías ferroviarias de alta elasticidad el conjunto de fijación del carril a la plataforma ha de tener unas características y comportamiento que favorezca dicha elasticidad.As is known, on the high railway tracks elasticity the rail fixing set to the platform must have characteristics and behavior that favors such elasticity.

Así, en las líneas de ferrocarril donde se necesita una fijación elástica entre el carril y la plataforma, es práctica común la utilización de fijaciones que emplean un muelle sobre el tornillo de anclaje para dar al conjunto la amortiguación adecuada al tipo de elasticidad solicitado.So, on the railway lines where you it needs an elastic fixation between the rail and the platform, it is common practice the use of fixings that employ a spring on the anchor screw to give the assembly the damping appropriate to the type of elasticity requested.

Estas fijaciones suelen estar compuestas por la placa de asiento del carril, un elastómero situado entre la placa y la plataforma, un casquillo de material aislante, un muelle y el tornillo de anclaje.These fixations are usually composed of rail seat plate, an elastomer located between the plate and the platform, an insulating bush, a spring and the anchor bolt

Esta solución, sin embargo, presenta básicamente dos problemas, por una parte que el tornillo se afloja al paso de las circulaciones, lo que obliga a tener que anclarlo fijo a la plataforma y montarlo con una tuerca autoblocante que impida la pérdida del muelle, y por otra parte, que dicho tornillo trabaja sometido a esfuerzos de flexión, lo que le obliga a diseñarlo con una sección mayor para absorber esfuerzos imprevistos.This solution, however, basically presents two problems, on the one hand that the screw is loosened to the passage of the circulations, which forces to have to anchor it fixed to the platform and mount it with a self-locking nut that prevents the loss of the spring, and on the other hand, that said screw works subjected to bending efforts, forcing you to design it with a larger section to absorb unforeseen efforts.

Es pues, el objetivo de la presente invención evitar dichos inconvenientes mediante el desarrollo de una fijación que incorpore los medios necesarios para conseguirlo de manera sencilla pero eficaz, haciendo que la fijación, sin dejar de perder su necesaria elasticidad, sea estable y segura, debiendo señalarse que por parte del solicitante se desconoce la existencia de ninguna otra invención que, con similar aplicación, presente unas características técnicas, estructurales y constitutivas semejantes a las que presenta la nueva fijación aquí preconizada.It is therefore the objective of the present invention avoid such inconveniences by developing a fixation that incorporates the necessary means to achieve it simple but effective, making fixing, while losing its necessary elasticity, be stable and safe, should be noted that the existence of any of the applicants is unknown another invention that, with similar application, presents some technical, structural and constitutive characteristics similar to those presented by the new fixation recommended here.

Explicación de la invenciónExplanation of the invention.

Así, la fijación elástica con ajuste de posición aplicable en vías ferroviarias que la presente invención propone se configura como una novedad dentro de su campo de aplicación, a tenor de cuya implementación y de forma taxativa, se alcanzan satisfactoriamente los anteriormente señalados objetivos, estando los detalles caracterizadores que la distinguen de lo ya conocido convenientemente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva.Thus, elastic fixation with position adjustment applicable on railway tracks that the present invention proposes are configured as a novelty within its scope, according to whose implementation and taxation, are achieved satisfactorily the aforementioned objectives, being the characterizing details that distinguish it from what is already known conveniently set forth in the final claims that accompany this specification.

De manera concreta lo que la invención preconiza es una fijación elástica que, para evitar la problemática descrita en el apartado anterior, se configura esencialmente de manera convencional con la particularidad de incorporar una serie de elementos nuevos de estructura especialmente diseñada para mejorar el sistema.Specifically what the invention advocates it is an elastic fixation that, to avoid the problem described In the previous section, it is essentially configured conventional with the particularity of incorporating a series of new structure elements specially designed to improve the system.

Para ello dicha fijación, en el tornillo que incorporando un muelle sujeta la placa de asiento del carril y el elastómero situado entre dicha placa y la plataforma, en lugar de contar simplemente con un casquillo convencional de material aislante, incorpora un primer casquillo o casquillo externo de orificio excéntrico, que siendo de carácter rígido y fácil deslizamiento, es decir, baja fricción, abarca la parte inferior del tornillo en coincidencia con la placa y el elastómero, y sobre el cual se apoya el muelle elástico.To do this, fixation on the screw that incorporating a spring holds the rail seat plate and the elastomer located between said plate and the platform, instead of simply have a conventional material bush insulating, incorporates a first bushing or external bushing of eccentric hole, which being rigid and easy slip, that is, low friction, covers the bottom of the screw in coincidence with the plate and the elastomer, and on the which supports the elastic spring.

Pero, además, la fijación propuesta contempla un segundo casquillo o casquillo interior considerablemente más largo, el cual queda dispuesto internamente ajustado al primer casquillo y al muelle, es decir, abarcando ambos elementos, contemplándose además el conjunto con una arandela superior rígida que bloquea la salida del muelle y sendas arandelas elásticas justo debajo de la cabeza del tornillo.But, in addition, the proposed fixation contemplates a second bushing or inner bush considerably longer, which is arranged internally adjusted to the first bushing and to the pier, that is, covering both elements, contemplating also the set with a rigid upper washer that blocks the exit from the pier and elastic spring washers just below the screw head

De esta forma, sobre el casquillo interior, en cuyo interior se aloja el tornillo, se deslizan el casquillo exterior y el muelle, mientras que la arandela rígida superior evita que el muelle pierda el casquillo interior a la vez que da pretensión sobre el mismo por diferencia de alturas.In this way, on the inner sleeve, in whose inside the screw is housed, the bushing slide exterior and spring, while the upper rigid washer prevents that the spring loses the inner bushing while giving claim on it for difference in heights.

Por su parte, las arandelas elásticas complementan el sistema evitando que el tornillo se afloje.On the other hand, elastic washers complement the system preventing the screw from loosening.

Con este sistema se consigue fijar firmemente el casquillo interior utilizando el par de apriete nominal del tornillo.With this system it is possible to fix the inner bushing using the nominal torque of the screw.

Con esta disposición, por tanto, sobre el casquillo interior recaerán los esfuerzos de flexión que compartirá con el tornillo formando así una fijación mucho más resistente y evitando la fatiga prematura del conjunto de la misma.With this provision, therefore, on the inner bushing will fall the bending efforts that will share with the screw thus forming a much more resistant fixing and avoiding premature fatigue of the whole of it.

La descrita fijación elástica con ajuste de posición aplicable en vías ferroviarias representa, pues, una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora para tal fin, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita.The described elastic fixation with adjustment of applicable position on railway tracks thus represents a innovative structure of structural features and constitutives unknown so far for that purpose, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is requested.
