<p>PCT No. PCT/NO90/00163 Sec. 371 Date Jun. 16, 1992 Sec. 102(e) Date Jun. 16, 1992 PCT Filed Oct. 31, 1990 PCT Pub. No. WO91/07616 PCT Pub. Date May 30, 1991.A chain-like conveyor device (6) for protecting accommodation and controlled guidance of flexible cables/hoses/lines extending between a stationary unit, e.g. a fixed production platform (1), and a unit, e.g. a derrick (5), displaceable in relation thereto and movable in at least two directions (P1,P2) intersecting each other, wherein the displacement movements take place in parallel planes, e.g. horizontal planes, and wherein the conveyor device (6) mainly comprising interhinged chain link-like conveyor carriage members (6'), has a first stationary end (6") and a second end (6'") coupled (at 7') to the displaceable unit (5), so that the second end (6'") is brought to follow the displacement movements of the displaceable unit (5) in said planes, e.g. horizontal planes. The pivot axes (32') for the interhinged single members (6') extend perpendicular to said planes, e.g. horizontal planes. Moreover, the conveyor device (6) is assigned external guiding and guide means (14-16, 11,11') as well as a tensioning device (22-24,34). The tensioning device comprises an actuating means (22) attaching on the conveyor device (6) for slackness-accommodating tensioning thereof in any one of its various positions.</p> |
