The invention discloses an offshore dragging portal frame, relates to the field of ocean engineering machinery, and is used for solving the problems that an existing portal frame is single in limiting angle and large in load borne by a main structure, the offshore dragging portal frame comprises a base, supporting legs and a turning plate mechanism, and the base is provided with a first supporting part and a second supporting part; the supporting leg comprises a supporting leg main body and an auxiliary support fixedly connected with the supporting leg main body, and the supporting leg main body is rotatably connected with the base; the plate turnover mechanism comprises a supporting plate and a driving part which are connected with each other, the supporting plate is rotatably connected with the base, and the driving part is arranged on the base and used for driving the supporting plate to rotate relative to the base. Compared with a traditional gantry which only has a limiting position and can limit the supporting legs, the offshore dragging gantry has the advantages that the limiting position of the gantry can be increased, the load directly borne by a main structure is reduced, and the offshore dragging gantry has the advantages of being high in dragging operation safety and good in applicability.

    本发明公开一种海上拖曳门架,涉及海洋工程机械领域,用于解决现有门架限位角度单一,主结构所受载荷较大的问题,该海上拖曳门架包括:基座、支腿和翻板机构,基座设有第一支撑部和第二支撑部;支腿包括支腿主体及与支腿主体固定连接的辅助支撑,支腿主体与基座可转动地连接;翻板机构包括互相连接的支撑板和驱动部件,支撑板与基座可转动地连接,驱动部件设于基座上,并用于驱动支撑板相对基座转动。本发明的海上拖曳门架相比传统只有极限位置能够对支腿进行限位的门架,能够增加门架的限位位置,并降低主结构直接承受的载荷,具有拖曳作业安全性高,适用性好的优点。
