According to the hoisting tool and the hoisting method for hoisting the connecting rod of the marine diesel engine out of the engine, the hoisting tool is adopted to replace a bearing cover of a crank pin, hoisting points on the connecting rod are increased, and the connecting rod is dismounted and mounted in a cavity of the diesel engine in a traction mode through the multiple hoisting points; the hoisting tool comprises an upper-section stud, lower-section studs, a middle-section stud, a lifting lug, a fixing plate and a shackle connecting block, the middle-section stud is connected with the upper-section stud and the lower-section stud through threads, the middle-section stud and the upper-section stud and the lower-section stud are arranged in two large-end stud holes of a connecting rod, the fixing plate is connected between the bottom ends of the two lower-section studs, and the shackle connecting block is connected with the upper-section stud and the lower-section stud. And the shackle connecting block is connected to the bottom end of one of the lower-section studs after the fixing plate is detached, and the shackle connecting block becomes a lifting point on the connecting rod. According to the invention, the difficulty that the hoisting operation space in the cavity is narrow is overcome, the stability of connecting rod hoisting is improved, the damage to parts is avoided, the safety risk is reduced, the product quality is guaranteed, the operation efficiency is improved, and the hoisting device can adapt to hoisting of connecting rods with different sizes.

    一种用于船用柴油机连杆由机内吊出的吊装工具及吊运方法,采用吊装工具替换曲柄销的轴承盖,增加连杆上的吊点,利用多个吊点以牵引的方式在柴油机的腔体内对连杆进行拆出和安装;所述吊装工具包括上段螺柱、下段螺柱、中段螺柱、吊耳、固定板和卸扣连接块,其中,中段螺柱通过螺纹分别连接上段螺柱和下段螺柱,并且一起设置于连杆的两个大端螺柱孔中,固定板连接于两个下段螺柱的底端之间,与连杆一起环包住曲柄销,卸扣连接块在卸除固定板后连接于其中一个下段螺柱的底端,成为连杆上的一个吊点。本发明克服了腔体内吊运操作空间狭小的困难,提高了连杆吊运的稳定性,避免了零部件损伤,降低了安全风险,保障了产品质量,提升了作业效率,能够适应不同尺寸连杆的吊运。
