The invention discloses a quenching lifting appliance for a piston rod of a large low-speed marine diesel engine. A lifting bar is divided into an upper chain and a lower chain, the lower chain is connected with lifting lugs on the two sides of a tool, the tool is provided with a clamping ring formed by butt joint of a front semicircle and a rear semicircle, the inner diameter of the clamping ring is larger than the outer diameter of the piston rod and smaller than the square head end of the piston rod, one end of the front semicircle and one end of the rear semicircle are hinged to each other, corresponding connecting holes are formed in the other ends of the front semicircle and the rear semicircle, and the connecting holes are provided with connecting bolts in a matched mode. The piston rod is tensioned through the square head end of the piston rod so that the piston rod can be vertically hoisted and mounted on a medium-frequency quenching machine tool for quenching, the machine tool can be prevented from being collided and damaged, and the safety is improved.
大型低速船用柴油机活塞杆淬火吊具,通过吊杠分成上部下部链条,下部链条与工装两侧的吊耳连接,工装为内径大于活塞杆外径、且小于活塞杆方头端的前半圆和后半圆对接的卡环,前半圆和后半圆一端相互铰接,前半圆和后半圆另一端都带有对应的连接孔,连接孔配合有连接螺栓。通过活塞杆方头端将活塞杆拉紧,使得活塞杆可以竖直进行吊装并安装在中频淬火机床上进行淬火,可以避免撞伤机床,提高了安全性。
