Description

LÍNEA DE VIDA VERTICAL PARA TRABAJOS EN ALTURA  VERTICAL LIFE LINE FOR WORK AT HEIGHT
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a una línea de vida vertical con cable para trabajos en altura que comprende un sistema superior de anclaje del cable que permite la parada progresiva del usuario en caso de caída y evita lesiones en el mismo, absorbiendo parte del impacto cuando se bloquea el dispositivo anticaída, de manera que el usuario no tiene que absorber la totalidad de dicho impacto. The present invention relates to a vertical lifeline with cable for work at height that comprises a superior cable anchoring system that allows the user to gradually stop in the event of a fall and avoid injury to it, absorbing part of the impact when it blocks the fall arrest device, so that the user does not have to absorb all of said impact.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Se conocen en el estado de la técnica las líneas 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 rehabilitación, o cualquier trabajo vertical que requiera ascensión por algún medio manual, como escaleras, o mecánico, como elevadores. Estas líneas de vida garantizan la seguridad de los usuarios en caso de que estos caigan desde alturas elevadas. The lifelines 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 the wind turbine towers, communications towers, buildings in rehabilitation, or any vertical work that requires ascension by some manual means, such as stairs, or mechanical, such as elevators. These lifelines guarantee the safety of users in case they fall from high heights.
Las líneas de vida conocidas incorporan un cable que se dispone paralelo al sistema de ascensión, de manera que los usuarios se enganchan respecto de dicho cable con medios de bloqueo que son susceptibles de liberarse mediante una sencilla manipulación para deslizar por el cable, permitiendo así el ascenso del usuario, pero de modo que si éste pierde la sujeción respecto del sistema de ascensión queda enganchado al cable sin caer. The known lifelines 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 líneas de vida debe ir anclado de una manera segura en la parte superior, ya que ese punto es el que tiene que soportar la sustentación del cable, así como toda la carga que quede sujetada al mismo. Para ello se conoce la solución presentada en el Modelo de Utilidad español con número de publicación ES1055904U que divulga un anclaje para una línea de vida en una escalera vertical, del tipo que comprende un amarre superior de suspensión para el colgado de un cable por delante de la escalera de aplicación, donde el amarre de suspensión se constituye por una pieza de configuración en "U", cuyas ramas laterales están 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 línea de vida, disponiéndose la pieza en acoplamiento de encaje, mediante sus ramas laterales, sobre unas pletinas de sujeción de la escalera en el montaje de instalación. The cable of these lifelines must be anchored securely at the top, since that point is the one that has to support the cable support, as well as all the load that is attached to it. For this, the solution presented in the Spanish Utility Model with publication number ES1055904U is known, which discloses an anchor for a lifeline in a vertical staircase, of the type comprising a top suspension mooring for the hanging of a cable in front of the application ladder, where the suspension tie 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 The cable tie of the lifeline is established, the piece being arranged in a coupling with its lateral branches, on some clamps for securing the ladder in the installation assembly.
A dicho amarre o sistema superior de anclaje se fija el cable en el que se encuentra acoplado un dispositivo anticaída al que van fijados a su vez unos medios de anclaje donde el usuario engancha su arnés de sujeción. El dispositivo anticaída es desplazable a lo largo del cable y es bloqueado/desbloqueado a lo largo del mismo por el usuario durante su ascenso o descenso por la escalera vertical. To said mooring or upper anchoring system, the cable is attached to which a fall arrest device is attached, to which anchors are attached, in which the user hooks his holding harness. The fall arrest device is movable along the cable and is locked / unlocked along the cable by the user during its ascent or descent by the vertical ladder.
El anterior sistema superior de anclaje del cable puede provocar lesiones en el usuario si este cae al vacío debido a la rigidez del mismo, ya que la zona del cuerpo del usuario donde va acoplado el arnés de sujeción debe absorber todo el impacto que supone el bloqueo del dispositivo anticaída de forma instantánea. The previous upper cable anchoring system can cause injuries to the user if it falls into a vacuum due to the rigidity of the cable, since the area of the body of the user where the clamping harness is attached must absorb all the impact of the blocking of the fall arrest device instantly.
Los sistemas conocidos del estado de la técnica no permiten además informar de manera instantánea de la caída del usuario, con el consiguiente retardo a la hora de establecer un plan de rescate y/o seguridad adecuado en caso de que sea necesario. The systems known in the state of the art also do not allow instantaneously to report the fall of the user, with the consequent delay in establishing an appropriate rescue and / or safety plan if necessary.
Además dichos sistemas tienen el inconveniente de que rompen la cadena de seguridad durante la operación de quitar y poner el dispositivo anticaída. La línea de vida de la presente invención solventa todos los inconvenientes comentados con anterioridad. Furthermore, said systems have the disadvantage that they break the safety chain during the operation of removing and putting on the fall arrest device. The lifeline of the present invention solves all the drawbacks discussed above.
