The invention relates to an offshore transfer side bridge containing a three-degree-of-freedom stabilized platform, which comprises a folding and unfolding platform, a revolving platform, a waiting platform, a variable-amplitude oil cylinder and a telescopic side bridge, the folding and unfolding platform comprises a lower platform, folding driving branches and an upper platform, and the folding driving branches are uniformly distributed between the lower platform and the upper platform; the folding and unfolding platform can be driven to be folded and unfolded by driving the auxiliary oil cylinder and the driving electric cylinder, the rotating platform is arranged on the upper platform, the waiting platform is arranged on the rotating platform, the rear end of the waiting platform is rotationally connected with a rotating support on the rotating platform, and the telescopic side bridge is arranged at the front end of the waiting platform. And the variable-amplitude oil cylinders are symmetrically arranged on the two sides of the telescopic side bridge. The parallel mechanism and the telescopic broadside bridge are combined, the influences of rolling, pitching, heaving and the like caused by sea waves on the ship can be actively compensated, the difficulty of offshore operation of the ship can be reduced, the operation efficiency can be improved, the collision risk can be reduced, and stable operation under various sea conditions can be achieved.
本发明涉及一种含三自由度稳定平台的海上转运舷桥,其包括折展平台、回转平台、等待平台、变幅油缸和伸缩舷桥,折展平台包括下平台、折叠驱动分支和上平台,折叠驱动分支均布设于下平台和上平台之间,通过驱动辅助油缸和驱动电缸的能带动折展平台的折叠及展开,且回转平台设于上平台上,等待平台设于回转平台上,且等待平台的后端与回转平台上的回转支座转动连接,伸缩舷桥设于等待平台的前端,且变幅油缸对称设于伸缩舷桥的两侧。本发明将并联机构与伸缩舷桥相组合,能够主动补偿海浪对船舶造成的横摇、纵摇、垂荡等影响,可以船只减小海上作业的难度,提高作业效率,减少碰撞风险,可以实现在多种海况下进行稳定作业。
