MOVABLE PIER
PROBLEM TO BE SOLVED: To provide a movable pier excellent in stability capable of restraining rocking of a bridge girder part even to unexpected sudden wave motion.SOLUTION: The bridge girder part 7 of the movable pier 1 having a top plate 6a supported by a 6-degree of freedom motion base 2 and the bridge girder part 7 extended in the lateral direction from the top plate 6a, is constituted by connecting a plurality of divided bodies 7A, 7B and 7C in the longitudinal direction, and the divided bodies 7B and 7C connected via a horizontal rotation mechanism 8 are made rotatable in the horizontal direction around the horizontal rotation mechanism 8, and the divided bodies 7A and 7B connected via a vertical rotation mechanism 9 are made rotatable in the vertical direction around the vertical rotation mechanism 9.
【課題】予期できない突発的な波動に対しても橋桁部の動揺を抑制できる安定性に優れた可動式桟橋を提供する。【解決手段】６自由度モーションベース２により支持された天板６ａと、天板６ａから横方向に延長された橋桁部７とを備えた可動式桟橋１の橋桁部７を複数の分割体７Ａ、７Ｂ、７Ｃを長手方向に接続して構成し、水平回転機構８を介して接続した分割体７Ｂ、７Ｃを水平回転機構８を中心にして水平方向に回動可能にするとともに、上下回転機構９を介して接続した分割体７Ａ、７Ｂを上下回転機構９を中心にして上下方向に回動可能にした。【選択図】図１
