The invention belongs to the technical field of auxiliary hoisting devices for construction, in particular to an auxiliary hoisting device for offshore pipeline construction. The auxiliary hoisting device for offshore pipeline construction comprises a hoisting column, wherein a column base is arranged at the bottom end of the hoisting column, a fixed lazy arm is arranged at the top end of the hoisting column, an adjustable lazy arm is arranged on the side wall of the hoisting column, a lazy arm fixing bolt is arranged in the adjustable lazy arm, a direction adjusting ring plate is arranged onthe outer surface wall of the hoisting column, and a rope positioning block is arranged at the top end of the fixed lazy arm. By matching the hoisting column, the column base, the fixed lazy arm, theadjustable lazy arm, the lazy arm fixing bolt, the direction adjusting ring plate, the rope positioning block and a fixed bolt hole, the device body is simple in structure, reasonable in design, convenient to operate and solid and durable, can be used circularly and not only improves the construction level of offshore trestle pipeline construction greatly, but also can solve the problem that it ishard to mount the offshore pipeline when there is no hoisting operation ship to support construction effectively.
本发明属于建造辅助吊装装置技术领域,尤其为海上管线建造辅助吊装装置,包括吊装立柱,吊装立柱的底端设置有立柱底座,且吊装立柱的顶端设置有固定吊臂,吊装立柱的侧壁上设置有可调吊臂,可调吊臂的内部设置有吊臂固定螺栓,吊装立柱的外表壁设置有方向调整环板,固定吊臂的顶端设置有绳索定位块。本发明通过吊装立柱、立柱底座、固定吊臂、可调吊臂、吊臂固定螺栓、方向调整环板、绳索定位块和固定螺栓孔的配合,使得该装置本体的结构简单、设计合理、操作便捷、结实耐用,并且可循环利用,不仅大幅度提高了海上栈桥管线建造施工水平,同时也能有效解决了没有吊装作业船支持时海上管线安装难的问题。
