MOVABLE PIER
PROBLEM TO BE SOLVED: To provide a movable pier, which is excellent in stability and can sufficiently restrict heaving of a bridge girder part that fluctuates even if the sea is rough.SOLUTION: A bridge girder part 7 is extended in lateral direction from above a top board 6a supported by 6-degrees of freedom motion base 2. The bridge girder part 7 is directly or indirectly pivotally supported by and installed on the top board 6a so as to be capable of rising and falling. A posture of the top board 6a is controlled by the 6-degrees of freedom motion base 2. Vertical distance d between a tip of the bridge girder part 7 and a top face of an object 13 is detected by an unevenness sensor 10, and an operation of a cylinder 9 is controlled by a corrugation control device 11 based on the detection data, which causes the bridge girder part 7 to rise or fall. Thus, the vertical distance d is controlled within an allowable range in order to enable a person to pass through the bridge girder part 7 to the object 13.SELECTED DRAWING: Figure 4
【課題】波が荒い場合であっても動揺する橋桁部のヒーブを十分に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の上方から横方向に橋桁部７を延設し、橋桁部７を天板６ａに直接または間接的に軸支して起伏可能に設置し、６自由度モーションベース２により天板６ａの姿勢制御を行うとともに、段差センサ１０により橋桁部７の先端部と対象物１３の上面との上下距離ｄを検知し、この検知データに基づいて起伏制御装置１１によりシリンダ９の動作を制御して橋桁部７を起伏させることにより、上下距離ｄを所定の許容範囲内に制御して、この橋桁部７を通じて対象物１３に対する人の往来を可能にする。【選択図】図４
