The invention discloses a pile lifting device type self-releasing and recycling gravity anchor, the gravity anchor is lowered through a pile lifting device, an ROV or a diver only needs to operate a pile lifting device releasing switch underwater to achieve releasing operation, due to the fact that the lifting tonnage of the pile lifting device is large, the lifting capacity can cover the weight of the gravity anchor used for subsea pipeline laying, a sling does not need to be matched repeatedly, and the lifting efficiency is greatly improved. The construction cost is saved.
本发明公开了一种吊桩器式自释放回收重力锚,通过吊桩器将重力锚下放,ROV或潜水员在水下只需操作吊桩器释放开关实现脱扣作业,且由于吊桩器吊重吨位大,该吊重能力可覆盖海管铺设用到的重力锚重量,不需重复匹配吊索具,节省施工成本。
