The invention relates to an offshore wind turbine blade hoisting buffer clamp which comprises a clamping device, a deflection device and a buffer device, the clamping device is used for clamping and fixing a wind turbine blade at a hoisting point position, so that the blade and the clamp are in close contact in the hoisting process, and no relative displacement is generated; the deflection device is used for adapting to multi-angle and non-directional shaking occurring in the blade hoisting process, the clamping device is allowed to have deflection within a certain range under the action of wind load, eccentric load, installation disturbance and the like, and the buffering device is used for reducing impact acting force generated by the deflection device in the hoisting process. And the buffer device elastically deforms to absorb kinetic energy, so that the displacement rate of the blades is prevented from being too high, and the whole clamp keeps high stability under the action of an external load.

    本发明涉及一种海上风机叶片吊装缓冲夹具,该夹具包括夹取装置、偏转装置和缓冲装置,所述夹取装置用于在吊点位置夹住并固定风机叶片,使叶片与夹具在吊装过程中紧密接触,不产生相对位移,所述偏转装置用于适应叶片吊装过程中出现的多角度及不定向晃动,允许夹取装置在风荷载、偏心荷载以及安装扰动等作用下具有一定范围的偏转量,所述缓冲装置用于减轻吊装过程中偏转装置产生的冲击作用力,缓冲装置发生弹性变形起到吸收动能的作用,防止叶片的位移速率过大,使得整个夹具在外荷载作用下保持较高的稳定性。
