Abstract

La invención proporciona un conjunto de perno de fricción que incluye: un manguito extensible que tiene un cuerpo tubular que se extiende longitudinalmente entre un extremo de entrada y un extremo de salida, cuerpo el cual tiene una formación que se extiende longitudinalmente, alrededor de la cual el cuerpo se deforma elásticamente, y formación la cual se extiende a lo largo de al menos parte del cuerpo, terminando en el extremo de entrada de cuerpo; una varilla que se extiende longitudinalmente a través del cuerpo de manguito y entre un primer extremo y un segundo extremo y sobre la que una parte que sobresale se define entre el extremo de salida del cuerpo de manguito y el segundo extremo; un elemento de expansión montado sobre o formado de manera solidaria con la varilla en o hacia el primer extremo; una primera formación de soporte de carga montada sobre la parte que sobresale de la varilla y que puede moverse a lo largo de la parte que sobresale para ponerse a tope con el extremo de salida del manguito; medios aplicadores de carga montados sobre la parte que sobresale de la varilla entre la primera formación de soporte de carga y el segundo extremo; una segunda formación de soporte de carga montada por encima de la parte que sobresale de la varilla entre la primera formación de soporte de carga y los medios aplicadores de carga; en el que los medios aplicadores de carga pueden hacerse actuar en contacto con la segunda formación de soporte de carga, cuando la segunda formación de soporte de carga está en enganche de soporte con una cara de roca que va a soportarse y cuando la primera formación de soporte de carga está en enganche de soporte con el extremo de salida del cuerpo de manguito, para llevar el elemento de expansión al interior de y a través del cuerpo de manguito desde el extremo de salida para provocar que el cuerpo tubular se deforme radialmente hacia fuera alrededor de la formación que se extiende longitudinalmente.
