Antecedentes de la invencionBackground of the invention
Se conocen en el estado de la tecnica las lmeas de vida para trabajos verticales, sobre todo cuando dichos trabajos se llevan a cabo a gran altura, como es el caso de las escaleras interiores de las torres de los aerogeneradores, de torres de comunicaciones, edificios en rehabilitacion, o cualquier trabajo vertical que requiera ascension por algun medio manual, como escaleras, o mecanico, como elevadores. Estas lmeas de vida garantizan la seguridad de los usuarios en caso de que estos caigan desde alturas elevadas.Life lines for vertical works are known in the state of the art, especially when such works are carried out at high altitude, as is the case with the internal stairs of wind turbine towers, communication towers, buildings in rehabilitation, or any vertical work that requires ascension by some manual means, such as stairs, or mechanical, as elevators. These life lines guarantee the safety of the users in case they fall from high heights.
Las lmeas de vida conocidas incorporan un cable que se dispone paralelo al sistema de ascension, de manera que los usuarios se enganchan respecto de dicho cable con medios de bloqueo que son susceptibles de liberarse mediante una sencilla manipulacion para deslizar por el cable, permitiendo asf el ascenso del usuario, pero de modo que si este pierde la sujecion respecto del sistema de ascension queda enganchado al cable sin caer.The known life lines incorporate a cable that is arranged parallel to the ascension system, so that the users are hooked with respect to said cable with blocking means that are capable of being released by a simple manipulation to slide along the cable, thus allowing the ascent of the user, but so that if he loses his grip on the ascension system he is hooked to the cable without falling.
El cable de dichas lmeas de vida debe ir anclado de una manera segura en la parte superior, ya que ese punto es el que tiene que soportar la sustentacion del cable, asf como toda la carga que quede sujetada al mismo.The cable of these life lines must be anchored in a safe way in the upper part, since that point is the one that has to support the support of the cable, as well as all the load that is attached to it.
Para ello se conoce la solucion presentada en el Modelo de Utilidad espanol con numero de publicacion ES1055904U que divulga un anclaje para una lmea de vida en una escalera vertical, del tipo que comprende un amarre superior de suspension para el colgado de un cable por delante de la escalera de aplicacion, donde el amarre de suspension se constituye por una pieza de configuracion en "U", cuyas ramas laterales estan provistas con sendas ranuras abiertas desde el extremo, mientras que la rama central posee en la zona media un orificio respecto del cual se establece el amarre del cable de la lmea de vida, disponiendose la pieza en acoplamiento de encaje, mediante sus ramas laterales, sobre unas pletinas de sujecion de la escalera en el montaje de instalacion.For this, the solution presented in the Spanish Utility Model with publication number ES1055904U that discloses an anchor for a life line on a vertical ladder, of the type comprising a top suspension mooring for the hanging of a cable in front of it, is known the application ladder, where the suspension mooring is constituted by a "U" configuration piece, whose lateral branches are provided with open grooves from the end, while the central branch has a hole in the middle area with respect to which The cable tie of the life line is established, the piece being arranged in a mating coupling, through its lateral branches, on some fastening strips of the ladder in the installation assembly.
