A truss type sail lifting device is characterized in that a slewing mechanism is fixed on a deck, an air cylinder and a truss type mast are fixed on the slewing mechanism, the air cylinder is positioned in the center inside the truss type mast, and a cylinder body of the air cylinder is fixed with the slewing mechanism. Pulley blocks are bilaterally symmetrically fixed on one edge of the top of the square truss-type mast, each pulley block is formed by arranging two first fixed pulleys side by side, a second fixed pulley is fixed below the middle of each pulley block and at the top of a piston rod of the air cylinder, and two ends of a steel wire rope penetrate out of the bottom of the second fixed pulley upwards, bypass the pulley blocks downwards and are connected with a frame in the center of the sail surface. The frame is a square frame, is located in the center of the top of the sail face, is sleeved outside the truss-type mast and is in sliding connection with the truss-type mast. The truss type mast fixed on the ship is used for replacing a hydraulic lifting mast, the oil leakage risk of hydraulic rod pieces is avoided, and the sail cost is reduced.

    一种桁架式风帆升降装置,回转机构固定在甲板上,回转机构上固定有气缸及桁架式桅杆,气缸位于桁架式桅杆内部中心,气缸的缸体与回转机构固定。在方形桁架式桅杆顶部的一条边上、左右对称固定有滑轮组,滑轮组是两个第一定滑轮并排设置,在滑轮组中间下方、气缸的活塞杆顶部固定有第二定滑轮,钢丝绳两端自第二定滑轮底部穿出向上,绕过滑轮组向下与帆面中心的框架连接。框架为方形框架,位于帆面顶部中心,框架套在桁架式桅杆外部,与桁架式桅杆滑动连接。本发明使用固定于船上的桁架式桅杆代替液压升降桅杆,避免液压杆件漏油风险,降低风帆成本。
