The invention relates to the technical field of cable laying ships, in particular to a large-angle pitching cable laying portal lifting and placing process which comprises the steps that a portal crane is used for carrying out lifting preparation, a lifted object ascends along with a steel cable till the steel cable is clamped to the position of a mouth-shaped limiting structure, and a variable-amplitude oil cylinder on the outer side of a portal rotates towards the inboard and outboard; and the hoisted object is lowered to the seabed or recovered to the deck, and the hoisted object is lifted and released through the anti-shaking frame and the cruise ship, so that the purpose of stably recovering and releasing the hoisted object is achieved, and the requirements of large-angle amplitude variation of the cable laying portal and seabed cable laying can be met.

    本发明涉及铺缆船技术领域,特别涉及一种大角度俯仰铺缆门架吊放工艺,包括使用门型吊进行起吊准备,被吊物随钢缆绳上升,直到钢缆绳卡到口形限位结构位置,通过门架外侧的变幅油缸向舷内和舷外转动,对被吊物下放海底或者回收到甲板上,并通过防晃架和游轮起放被吊物,达到被吊物稳定收放的目的,以此,能够满足铺缆门架的大角度变幅以及海底铺缆需求。
