Abstract

Le dispositif selon l'invention est particulièrement adap­ té au nettoyage et au contrôle des noeuds d'une structure sous-marine comportant plusieurs branches 1, 2, 3, 4. Le dispositif selon l'invention comprend un support annulaire formé par deux tores (5) reliés par des traverses (6) et pouvant être disposés autour d'une branche de la structure, un chariot (7) mobile sur le support annulaire et portant un élément tubulaire (8) supportant un bras porte-outils (9) mobile suivant au moins une direction parallèle à l'axe du support annulaire et à l'extrémité duquel est monté de façon articulée un support d'outils (10) sur lequel est monté un outil (11). The device according to the invention is particularly suitable cleaning and checking the nodes of a structure submarine with several branches 1, 2, 3, 4. The device according to the invention comprises an annular support formed by two toroids (5) connected by crosspieces (6) and can be arranged around a branch of the structure, a carriage (7) movable on the annular support and carrying a tubular element (8) supporting a tool-carrying arm (9) movable in at least one direction parallel to the axis of the annular support and at the end of which is mounted so articulated tool holder (10) on which is mounted a tool (11).
