The invention discloses a motion compensation floating support installation method applying a three-degree-of-freedom platform, and belongs to the technical field of offshore operation platform installation. A barge deck, a plurality of three-degree-of-freedom stable block devices with action lines of three hydraulic rods intersecting at one point and a plurality of hydraulic jacks are used, a center passive hydraulic supporting device comprises a hydraulic cylinder and the hydraulic rods installed in the hydraulic cylinder, and the lower end of the hydraulic cylinder is connected with a hinge piece capable of achieving three-degree-of-freedom movement. The driving branch comprises a hydraulic cylinder, a hydraulic rod and a servo valve for providing driving force for the hydraulic rod, the upper end and the lower end of the hydraulic rod are connected with hinge pieces capable of enabling the driving branch to move on three degrees of freedom, and the three rods at the upper end share one hinge piece; the hydraulic jack comprises a jack head, an oil cylinder, a piston, an oil nozzle, a base and a universal hinge piece. The combination device is simple in structure, the action lines of the three rods of the three-degree-of-freedom stable platform intersect at one point, control is convenient, and the influence of waves on the offshore installation platform is effectively reduced.

    本发明公开了一种应用三自由度平台的运动补偿浮托安装方法,属于海上作业平台安装的技术领域。本发明使用驳船甲板、若干三液压杆作用线交于一点的三自由度稳定组块装置和若干液压千斤顶,所述中心被动液压支撑装置包括液压缸以及安装在液压缸中的液压杆,所述液压缸的下端连接有可实现这三自由度运动的铰接件,所述驱动分支包括液压缸、液压杆以及给杆提供驱动力的伺服阀,所述液压杆的上下两端均连接有可实现驱动分支在三个自由度上运动的铰接件,上端三杆共用一铰接件;所述液压千斤顶包括顶头、油缸、活塞、油嘴和基座,万向铰接件。本发明结构简单,三自由度稳定平台三杆作用线交于一点,便于控制且有效降低波浪对海上安装平台造成的影响。
