The invention discloses a diving bell lifting and placing swing stopping portal frame and a diving bell lifting and placing method, and belongs to the technical field of diving equipment. The diving bell lifting and placing swing stopping portal frame comprises a base frame, a portal frame body, a variable-amplitude oil cylinder, a swing stopping frame assembly and a swing stopping oil cylinder, wherein the portal frame is hinged to the base frame; one end of the variable-amplitude oil cylinder is hinged to the portal frame body, and the other end of the variable-amplitude oil cylinder is hinged to the base frame; the swing stopping frame assembly comprises a swing stopping frame body and a hook, and a diving bell and the swing stopping frame body can be fixed into a whole through the hook; the swing stopping frame body is hinged to a portal cross beam; one end of the swing stopping oil cylinder is hinged to the portal cross beam, and the other end of the swing stopping oil cylinder is hinged to the swing stopping frame body; and the diving bell lifting and placing swing stopping portal frame is configured to control the rotation angle of the swinging stopping frame assembly through the extension or shortening of the swing stopping oil cylinder. According to the diving bell lifting and placing swing stopping portal frame and the diving bell lifting and placing method, the swing of the diving bell fixedly connected with the swing stopping frame assembly is effectively reduced by utilizing the continuous expansion and contraction of the swing stopping oil cylinder, so that the inclination of the swing stopping frame caused by the amplitude variation motion can be prevented, and the inclination of the swing stopping frame caused by the front-back inclination angle of a mother ship can also be prevented.
本发明公开了一种潜水钟吊放止荡门架及潜水钟吊放方法,属于和潜水设备技术领域,包括,基架、门架、变幅油缸、止荡架组件和止荡油缸;其中,门架与基架铰接;变幅油缸一端与门架铰接,另一端与基架铰接;止荡架组件包括止荡架体和挂钩,挂钩能够将潜水钟与止荡架体固定为一体;止荡架体与门架横梁铰接;止荡油缸一端与门架横梁铰接,另一端与止荡架体铰接;潜水钟吊放止荡门架配置成通过止荡油缸的伸长或缩短控制止荡架组件的旋转角度。本发明利用止荡油缸不断的伸缩,有效减小与止荡架组件固定连接的潜水钟的摆动,既可以防止变幅运动本身造成的止荡架倾斜,还可以防止母船的前后倾角造成的止荡架倾斜。
