The invention relates to a hoisting method for a steering engine hydraulic plunger of an LNG (liquefied natural gas) transport ship. The hoisting method comprises the following steps that a hoisting ring is fixed to one end of the steering engine hydraulic plunger, and after the auxiliary hoisting tool is fixed to the other end of the steering engine hydraulic plunger, the steering engine hydraulic plunger is hoisted to a vertical state by using a crane, the steering engine hydraulic plunger is moved to a position above a steering engine room, the steering engine hydraulic plunger is hoisted into the steering engine room through a hoisting hole, and the hoisting auxiliary tool makes contact with the ground and supports the ground, so that the steering engine hydraulic plunger is controllably and slowly placed on wood of a floor. The invention further relates to the hoisting auxiliary tool. The hoisting auxiliary tool structurally comprises a support (1), a plunger gasket (9), a shaft (4) and two bearing wheels (2), and the two bearing wheels (2) are fixed to the two sides of the support (1) through the two ends of the shaft (4) respectively. According to the method and the tool, achromium plating layer at the landing end of the plunger in the hoisting state can be protected, the use of a chain block is omitted, the labor cost required by hoisting is reduced, and the hydraulicplunger hoisting construction time is shortened.

    本发明涉及到一种LNG运输船的舵机液压柱塞的吊装方法,该方法在舵机液压柱塞的一端固定吊环,另一端固定吊装辅助工装后,用吊车吊拉至竖直状态后移动至舵机舱上方,通过吊物孔后吊入至舵机间内,通过吊装辅助工装与地面接触并支撑,实现舵机液压柱塞可控缓慢地放置到地板的木头上;还涉及到吊装辅助工装,结构包括有支架(1)、柱塞垫片(9)、轴(4)和承重轮(2),两个所述的承重轮(2)分别通过轴(4)的两端固定在支架(1)的两侧。本发明的方法和工装能够对柱塞吊装状态的落地端镀铬层进行保护、省掉手拉葫芦使用、降低吊装所需人工成本、减少液压柱塞吊装施工时间。
