The invention relates to the technical field of diesel engines, and discloses a marine diesel engine frequency modulation wheel lifting tool which comprises a lifting tool body, a frequency modulation wheel and a main lifting plate, connecting bolts are installed at the two ends of one side of the bottom of the lifting tool body, and the connecting bolts penetrate through the two ends of the frequency modulation wheel; although frequency modulation wheels of the same diesel engine are different in structure, the pitch circle diameters of tool holes of the frequency modulation wheels are the same, the tool holes of the frequency modulation wheels are all threaded groove holes used for bolts, and the frequency modulation wheels inserted into the two ends of one side of the bottom of the lifting tool body are in threaded connection with the mounting screw grooves after being inserted into the mounting screw grooves. Therefore, the frequency modulation wheel can be stably installed on the hoisting tool body, the frequency modulation wheel can be matched with different frequency modulation wheels on the same diesel engine before hoisting and can be stably installed, and the manufacturing cost is reduced.

    本发明涉及柴油机技术领域,且公开了一种船舶柴油机调频轮起吊工具,包括起吊工具本体、调频轮和主吊板,所述起吊工具本体底部一侧两端均安装于连接螺栓,所述调频轮的两端均贯穿开凿有连接螺栓,所述起吊工具本体底部另一侧固定有吊耳,同一种柴油机的调频轮虽然结构不同,其工具孔的节圆直径相同,其工具孔均是用于螺栓用的螺纹槽孔,通过在起吊工具本体底部一侧的两端插设的调频轮与安装螺槽穿插后螺纹连接,从而使得调频轮能够稳定地安装在起吊工具本体上,进而使得其能够与同一种柴油机上不同调频轮进行起吊前的适配以及稳定的安装,降低了制造成本。
