A method and apparatus for connecting sections of a drilling rig substructure (5) is disclosed. The disclosed invention is a unique structural connector in which sections of a drilling rig substructure (5) can be connected together without the use of pins or pin-type connectors. The structural connector of the present invention utilizes specially-shaped fixed members (61, 62) connected to, and extending through, support plates (60) that are attached to sections of a drilling rig substructure (5) that mate with specially-shaped mating lugs (46, 47) that are mounted on mating lug plates (43, 44) that are attached to separate sections of the drilling rig substructure (5). When the sections of the drilling rig substructure (5) to be connected are positioned together, the specially-shaped mating lugs (46, 47) engage the specially- shaped fixed members (61, 62) and form a high strength structural connection between the sections of the drilling rig substructure (5).
L'invention concerne un procédé et un appareil servant à assembler des segments d'une infrastructure d'installation de forage (5). L'objet de l'invention est un connecteur de structure unique qui permet d'assembler des segments d'une infrastructure d'installation de forage (5) sans utiliser des chevilles ou des connecteurs à chevilles. Le connecteur de structure de l'invention met en oeuvre des éléments fixes spécialement façonnés (61, 62) reliés à, et traversant des plaques de support (60) fixées à des segments de l'infrastructure d'installation de forage (5) accouplés à de crans homologues spécialement façonnés (46, 47). Ces crans sont montées sur des plaques à crans (43, 44) fixées à des segments séparés de l'infrastructure d'installation de forage (5). Lorsque les segments de l'infrastructure d'installation de forage (5) à assembler sont réunis et mis en place, les crans homologues spécialement façonnés (46, 47) entrent en prise avec les éléments fixes spécialement façonnés (61, 62) et forment un assemblage de structure très solide entre les segments de l'infrastructure d'installation de forage (5).
