The invention relates to the technical field of sails in ship and ocean engineering, in particular to a winch mast sail face synchronous lifting type hard wing sail which comprises a sail base, the end face of the sail base is connected with a rotation driving assembly through a bolt, and the rotating end of the rotation driving assembly is connected with a mast supporting seat through a bolt. The glass fiber reinforced plastic composite material is adopted as a material of the sail blade skin and the sail blade frame, on one hand, the weight of the sail blade is reduced, on the other hand, the situation that the friction force of sail blade lifting is increased after steel corrosion is avoided, and a lifting system is changed into winch pulley lifting from hydraulic pressure, so that the lifting efficiency is greatly improved. The problems that a hydraulic system is complex, high in failure rate, large in system pressure, not in place in lifting, difficult in oil leakage sealing at a rotary joint, easy to stop and capable of maintaining pressure constantly are solved, a hydraulic station can be omitted after a winch system is adopted, and the problems that in practical application, the lifting system is high in failure rate and high in cost are effectively solved.
本发明涉及船舶与海洋工程中的风帆技术领域,尤其为一种绞车桅杆帆面同步升降型硬翼风帆,包括风帆基座,所述风帆基座的端面通过螺栓连接有回转驱动组件,所述回转驱动组件的旋转端通过螺栓连接有桅杆支撑座,所述桅杆支撑座的端部固定连接有固定桅杆,本发明通过采用玻璃钢复合材料作为帆叶蒙皮和帆叶框架的选材,一方面降低帆叶的重量,另一方面避免了钢材腐蚀后所增加帆叶升降的摩擦力,并且将升降系统由液压改为绞车滑轮升降,避免了液压系统复杂故障率高,系统压力大,升降不到位、旋转接头处漏油密封难、容易暴死,并且需要时时保压,改为绞车系统后可取消液压站,有效的解决在实际应用中发现该升降系统故障率多、成本高的问题。
