The invention belongs to the technical field of ocean engineering, and particularly relates to a traction labor-saving mechanism of a tilting sail device, which is characterized in that a movable pulley block and a fixed pulley block are arranged at a sail body and a base and are matched with a guide pulley block at the top of a support rod structure, so that steel wire rope threading is realized, steel wire rope tension is reduced, and winch load is reduced; and the economical efficiency and the applicability of the tilting sail device are improved. The problems that when the tilting sail is pulled up by a steel wire rope, large resistance bending moment can be generated, so that the tension of the steel wire rope is large, the winch load is large, and difficulty is brought to winch type selection and arrangement are solved.
本发明属于海洋工程技术领域,具体涉及一种可倾倒风帆装置的牵拉省力机构,通过在帆体及基座处设置动、定滑轮组,配合支撑杆结构顶部的导向滑轮组,实现钢丝绳穿线,降低钢丝绳拉力,减小绞车负载,提高可倾倒风帆装置的经济性和适用性。解决了可倾倒风帆处于被钢丝绳拉起状态时,会产生很大的阻力弯矩,导致钢丝绳拉力较大,造成绞车负载载荷较大,对绞车选型和布置带来难度的问题。
