The invention discloses a push-and-pull fork frame of a full-rotation hoisting pile driver for an offshore ship and a loading and unloading method of the push-and-pull fork frame. The push-and-pull fork frame comprises a first-stage fork frame, a second-stage fork frame, a third-stage fork frame, a first telescopic oil cylinder and a second telescopic oil cylinder. The rear end part of the primary fork frame is movably connected with the root position of the propeller strut; the rear end part of the second-stage fork frame is inserted into the front end part of the first-stage fork frame; the rear end part of the third-stage fork frame is inserted into the front end part of the second-stage fork frame; the front end part of the third-stage fork frame is movably connected with the middle position of the pile frame; the fixed end of the first telescopic oil cylinder is arranged on the first-stage fork frame, and the movable end of the first telescopic oil cylinder is arranged on the second-stage fork frame; the fixed end of the second telescopic oil cylinder is arranged on the second-stage fork frame, and the movable end of the second telescopic oil cylinder is arranged on the third-stage fork frame. A three-stage push-and-pull structure is adopted, the two ends of the push-and-pull structure are movably connected with the root of the propeller strut and the middle of the pile frame correspondingly, and the problems that an existing push-and-pull fork frame is inconvenient to mount/dismount and occupies a large deck area are solved.

    本发明公开了一种海上船用全回转起重打桩机的推拉叉架及其装卸方法,包括一级叉架框架、二级叉架框架、三级叉架框架、第一伸缩油缸和第二伸缩油缸;一级叉架框架的后端部与人字架的根部位置活动连接;二级叉架框架的后端部插装于一级叉架框架的前端部中;三级叉架框架的后端部插装于二级叉架框架的前端部中;三级叉架框架的前端部与桩架的中部位置活动连接;第一伸缩油缸的固定端设于一级叉架框架上,活动端设于二级叉架框架上;第二伸缩油缸的固定端设于二级叉架框架上,活动端设于三级叉架框架上。本发明采用三级推拉结构,且两端分别与人字架的根部和桩架的中部活动连接,解决了现有推拉叉架的安装/拆卸不便以及占用甲板面积大的问题。
