Title (EN) ELEVATOR DEVICE FOR A SEA PLATFORM
(FR) DISPOSITIF ELEVATEUR DE PLATEFORME MARINE
Abstract: front page image
(EN)A device, controlling the relative vertical displacements of the bridge (1) and of the feet (2) of a sea platform, comprises on one hand toothed-racks (31, 32) cut out in pillars (3) fixed to the feet and on the other hand locomotor units (5) which comprise each a frame (51) fitted with gears (55) rotatingly driven by motors (57, 58) and meshing with said toothedracks, and substantially characterized in that each frame of locomotor unit is attached by a joint (41) to a coupling rod (4) which extends along the pillar and is connected by a joint (42) to the bridge and associated to balancing means (81, 82, 83) of the reverse torque generated by the effort transmitted by said coupling rod. The device is intended to a platform for oil drillings.
(FR)Un dispositif, commandant les deplacements verticaux relatifs du pont (1) et des pieds (2) d"une plateforme marine, comporte d"une part des cremailleres (31, 32) taillees dans des montants (3) fixes aux pieds et d"autre par des blocs locomoteurs (5) qui comprennent chacun un chassis (51) equipe de pignons (55) entraines en rotation par des moteurs (57, 58) et engrenant sur lesdites cremailleres, et il est essentiellement caracterise par le fait que chaque chassis de bloc locomoteur est attache par une articulation (41) a une bielle d"accouplement (4) qui s"etend le long du montant et est attachee par une articulation (42) au pont et est associe a des moyens d"equilibrage (81, 82, 83) du couple de renversement engendre par l"effort que transmet ladite bielle. Le dispositif est destine a une plateforme pour les forages petroliers.
