Title: AUTOMATIC PANEL-FLIPPING MECHANISM FOR OFFSHORE DRILLING PLATFORM
Abstract:
Disclosed is an automatic panel-flipping mechanism for an offshore drilling platform, wherein an automatic panel-flipping mechanism (1) is mounted on one side of a marine riser crane (2) near a flippable platform (4) in the direction of a moving track (3) of the marine riser crane (2), the automatic panel-flipping mechanism (1) is composed of steel pipes welded to form a trapezoidal structure, and a lower bottom end (12) of the trapezoidal automatic panel-flipping mechanism (1) is lower than the lowermost end of the flippable platform (4). A purely mechanical structure is used for the mechanism, without the need for hydraulic and electrical control elements, thus saving on costs and being highly reliable.
