Three-degree-of-freedom offshore gallery bridge device with motion compensation capability
The invention discloses a three-degree-of-freedom offshore gallery bridge device with motion compensation capability, which comprises a telescopic gangway ladder and a three-degree-of-freedom stable platform, and the three-degree-of-freedom stable platform is movably connected below the telescopic gangway ladder. According to the device, three servo electric cylinders are adopted to control the pose of an upper stabilized platform of a three-degree-of-freedom stabilized platform in real time, and when a ship is subjected to complex disturbance generated by wind, wave and flow loads, main motion compensation control is carried out on an offshore gallery bridge device through real-time control over the three servo electric cylinders; so that the upper stable platform is kept in a horizontal state all the time, and then the gangway ladder is kept in the horizontal state, and therefore pose control over the offshore gallery bridge is achieved; furthermore a telescopic column is added on the three-degree-of-freedom stabilized platform for limiting torsion of the stabilized platform, rolling bearings are arranged on eight surfaces of the telescopic outer column and the telescopic inner column and are used for overcoming friction force generated in a platform movement process, so that the platform can quickly and stably operate.
本发明公开了一种具有运动补偿能力的三自由度海上廊桥装置，包括可伸缩舷梯和三自由度稳定平台，所述三自由度稳定平台活动连接在可伸缩舷梯的下方。该装置采用三个伺服电动缸对三自由度稳定平台的上稳定平台的位姿进行实时控制，当船舶受到风、浪、流载荷作用产生的复杂扰动时通过对三个伺服电动缸的实时控制，对海上廊桥装置进行主要的运动补偿控制，使上稳定平台一直保持在水平状态进而使舷梯也保持在水平状态，从而实现对海上廊桥的位姿控制，同时在三自由度稳定平台上加有伸缩立柱限制稳定平台的扭转，伸缩外柱和伸缩内柱的八个面上均装有滚动轴承用以克服平台运动过程中产生的摩擦力使平台快速稳定的运行。
