ABSTRACT:
This invention concerns a mechanism for the interchanging of guide-posts worked by remotely controlled vehicle which consists of guide-cones (6) provided in the side of base beam (2) that supports socket (4) of guide-post, which guide-cones are placed axially and enter all around the socket (4) of guide-post, to create an operating channel inside the socket (4) while guide-post (8) is provided with a channel all around its bottom (1) to house a locking-pin (12). Guide-post (8) is placed inside its respective socket (4) so that the operating channel created by the guide cones (6) inside socket (4) matches channel all round the bottom (10) of socket, exactly, so that locking of guide-post (8) takes place by means of turning the locking-pin (12) housed in channel all around (10) the guide-post (8) by means of a remotely operated vehicle or suitable tool.
