Abstract

UN DISPOSITIVO DE ABSORCION DE ENERGIA SE UTILIZA EN UN SISTEMA DE ABSORCION DE ENERGIA ACOPLADO A UN OBJETO. EL DISPOSITIVO DE ABSORCION DE ENERGIA CONSTA DE UN CUERPO QUE DEFINE UNA RANURA LONGITUDINAL QUE PASA A TRAVES DE EL PARA ALOJAR DOS CAPAS COMO MINIMO DE MATERIAL DE CUERDA EN UNA UNION ESTANCA. LAS CAPAS SE PUEDEN MOVER EN DIRECCIONES OPUESTAS, POR LO QUE, EN CASO DE DEMANDA DE ABSORCION DE ENERGIA, EL MATERIAL DE CUERDA SE MUEVE EN RELACION CON EL DISPOSITIVO DE ABSORCION DE ENERGIA, Y LA FRICCION PRODUCIDA ENTRE LA CUERDA Y EL DISPOSITIVO CONTROLA LA FUERZA APLICADA AL OBJETO. ESTA EQUIPADO CON UN SISTEMA PARA AUMENTAR EL ANCHO DE LA RANURA TRAS LA DETENCION DEL OBJETO, PARA REDUCIR LA FRICCION Y PERMITIR QUE EL OBJETO SE SIGA MOVIENDO DE FORMA CONTROLADA. LA INVENCION PERMITE UN DESCENSO EN DOS FASES, EN EL QUE TRAS UNA CAIDA, LA SEGUNDA FASE PERMITE UN DESCENSO CONTROLADO.AN ENERGY ABSORPTION DEVICE IS USED IN AN ENERGY ABSORPTION SYSTEM COUPLED TO AN OBJECT. THE ENERGY ABSORPTION DEVICE CONSISTS OF A BODY DEFINING A LONGITUDINAL SLOT THAT PASSES THROUGH IT TO ACCOMMODATE TWO LAYERS AT LEAST OF ROPE MATERIAL IN A SEALED UNION. THE LAYERS CAN BE MOVED IN OPPOSITE DIRECTIONS, SO, IN CASE OF DEMAND FOR ENERGY ABSORPTION, THE ROPE MATERIAL MOVES IN RELATION TO THE ENERGY ABSORPTION DEVICE, AND THE FRICTION PRODUCED BETWEEN THE ROPE AND THE DEVICE CONTROLS FORCE APPLIED TO THE OBJECT. IT IS EQUIPPED WITH A SYSTEM TO INCREASE THE WIDTH OF THE SLOT AFTER STOPPING THE OBJECT, TO REDUCE FRICTION AND ALLOW THE OBJECT TO KEEP MOVING IN A CONTROLLED WAY. THE INVENTION ALLOWS A DESCENT IN TWO PHASES, IN WHICH AFTER A FALL, THE SECOND PHASE ALLOWS A CONTROLLED DESCENT.
