Abstract

Ce porte-pic (110) est mis en place par friction par l'intermédiaire d'un barillet cylindrique (112) dans le casier à pics d'un mineur continu. En fonctionnement, un pic est disposé par rotation dans une âme (114) qui présente, sur sa partie arrière un filetage interne (30) orienté vers l'intérieur. Une fois le pic retiré, le porte-pic (110) est extrait du casier à pics par vissage d'une tige filetée dans ce filetage (30) et par application d'une force d'extraction au porte-pic (110) par l'intermédiaire de cette tige et des deux filetages qui sont en prise.
