The invention discloses a device for lifting a lifting-lug-free steel pipe pile and a construction method. The device is composed of a pile clamping device, a turning-over lifting appliance, a shackle and a steel wire rope, and the pile clamping device comprises a pile clamping main body structure, four clamps, a pile clamping device lifting lug, two turning-over lifting points, a plug pin structure and a hydraulic structure; the floating crane main hook and the pile gripper lifting lug are connected through a steel wire rope to form a pile-front lifting device of the steel pipe pile; the floating crane auxiliary hook is connected with a lifting appliance lifting lug at the top of the turnover lifting appliance through a steel wire rope to form the pile bottom turnover device of the steel pipe pile. Lifting of the lifting-lug-free steel pipe pile is achieved, the lifting-lug-free steel pipe pile is simple in composition structure, convenient to construct and easy to operate, the lifting lug does not need to be arranged when the steel pipe pile goes out, and the steel pipe pile manufacturing procedure is reduced; the pile clamping device can ensure that the steel pipe pile smoothly passes through the guide device, and the perpendicularity is ensured; the turning-over lifting appliance ensures that the steel pipe pile can be turned from horizontal to vertical after being lifted, and the lifting requirement is met.

    本发明公开了一种用于无吊耳钢管桩起吊的装置及施工方法,该装置由夹桩器、翻身吊具、卸扣和钢丝绳组成,其中:夹桩器包括夹桩主体结构、四个夹具、夹桩器吊耳、两个翻身吊点、插销结构和液压结构;浮吊主钩与夹桩器吊耳通过钢丝绳连接构成钢管桩的桩前起吊装置;浮吊副钩与翻身吊具顶部的吊具吊耳通过钢丝绳连接构成钢管桩的桩底翻身装置。本发明实现无吊耳钢管桩的起吊,且具有组成结构简单、施工方便、操作简单,钢管桩外出无需设置吊耳,降低了钢管桩制作的工序;夹桩器能确保钢管桩顺利通过导向装置,保证垂直度;翻身吊具确保钢管桩起吊后,能由平转竖,满足吊装需求。
