The invention discloses a pile leg lifting system of a wind power installation ship, which comprises a pile leg, a lifting air cylinder and two groups of clamping devices including a fixed clamping device and a movable clamping device, the fixed clamping device is arranged on the wind power installation ship on the periphery of the pile leg, the bottom of the lifting air cylinder is fixedly arranged on the fixed clamping device, and the movable clamping device is arranged on the bottom of the lifting air cylinder. The movable clamping device is arranged above the fixed clamping device and fixedly installed on the top of the output end of the lifting air cylinder, a plurality of sets of positioning holes are formed in the outer wall of the pile leg in an up-down array ring mode, and the fixed clamping device and the movable clamping device are both movably embedded and fixedly arranged in the positioning holes. The device has the advantages that the fixed clamping device and the movable clamping device are arranged, the lifting air cylinder and the movable clamping device clamp the pile leg and then drive the pile leg downwards to achieve stable single-time lowering, and after single-time lowering is completed, the pile leg is clamped through the lowered fixed clamping device, and after the movable clamping device releases clamping, the pile leg can be lowered to a certain degree. And the lifting air cylinder drives the movable clamping device to upwards clamp the pile leg, so that the pile leg is lowered for the second time, and otherwise, the pile leg is lifted.
本发明公开了一种风电安装船的桩腿升降系统,包括桩腿、升降气缸与夹持器,夹持器设置有两组,包括固定夹持器与活动夹持器,固定夹持器安装于桩腿外围的风电安装船上,升降气缸底部固定安装于固定夹持器上,活动夹持器设置于固定夹持器上方,且固定安装于升降气缸的输出端顶部,桩腿外壁上下阵列环设有多组定位孔,固定夹持器与活动夹持器均活动嵌合固定设置于定位孔内。本发明的优点在于通过设置固定夹持器与活动夹持器,升降气缸与活动夹持器对桩腿夹持后驱动向下实现稳定的单次下放,单次下放完成后,通过下放的固定夹持器对桩腿夹持,活动夹持器放开夹持后,升降气缸驱动活动夹持器向上再对桩腿夹持,实现第二次的下放,反之则对桩腿进行升起。
