OSCILLATION CORRECTION DEVICE
PROBLEM TO BE SOLVED: To provide a device with a small size at low cost which can prevent a bridge mechanism from damage and provide a safe access to an object even if a wave motion due to sporadic disturbance is generated.SOLUTION: An oscillation correction device 1 is provided with an oscillation correction mechanism 3 which correctively controls a table 4 in a horizontal manner by a hexapod structure of a six-axial system so as to restore the oscillation due to wave motion. The bridge mechanism 5 is connected to the table 4, and the bridge mechanism 5 is made to be rotatable in a vertical direction by a hinge part 12. A laser sensor 18 for measuring vertical and horizontal distances with respect to an offshore facility is installed on the undersurface of a tip end part 5a of the bridge mechanism 5. The oscillation correction mechanism 3 and the bridge mechanism 5 are controlled in terms of the operations thereof by the control means 10 based on the measurement data in vertical and horizontal directions with respect to the offshore facility measured by the laser sensor 18 so that the bridge mechanism 5 and the offshore facility are retained within the acceptable range to allow a non-contact access.SELECTED DRAWING: Figure 1
【課題】小型で低コストでありながら、突発的な外乱の波動が生じても架橋機構を損傷することを防止して安全に対象物にアクセスできる。【解決手段】動揺補正装置１は、波動による動揺を解消するように６軸システムのヘキサポッド構成によってテーブル４を水平に補正制御する動揺補正機構３を備えた。テーブル４に架橋機構５を接続し、架橋機構５はヒンジ部１２で上下方向に回動可能とした。架橋機構５の先端部５ａの下面に、洋上施設との水平方向及び上下方向の距離を測定するレーザセンサ１８を設置した。レーザセンサ１８で測定した洋上施設との間の水平方向及び上下方向の測定データに基づいて架橋機構５と洋上施設とを非接触でアクセス可能な許容範囲内に保持するように、制御手段１０で動揺補正機構３と架橋機構５を作動制御する。【選択図】図１
