Abstract

The invention belongs to the technical field of lifting tools, and particularly relates to a lifting tool for lifting large-mass thin-wall parts. The lifting tool comprises a lifting tool body, a connecting part, a rope wheel and an adapter plate. The connecting part is arranged at one end of the lifting tool body, the rope wheel is mounted on the connecting part, and the rope wheel can rotate around the central axis of the rope wheel. The adapter plate is fixedly mounted on one side of the connecting part through a mounting bolt. The rope wheel is cylindrical, and an annular groove is formedin the arc surface of the outer wall of the rope wheel. Multiple groups of second through holes are formed in the middle position of the plate surface of the adapter plate, a first mounting plate is arranged at the other end of the lifting tool body, and multiple groups of fifth through holes are formed in the first mounting plate. The first mounting plate and the adapter plate on the lifting toolcan adopt small-specification screws, and by means of a bolt group forming manner, the large-mass thin-wall parts are lifted.

Description

technical field [0001] The invention belongs to the technical field of slings, in particular to a sling used for lifting large-mass thin-walled parts. Background technique [0002] At present, the "two cranes and one crane" framework adopted in China is used to test the RCS (Radar Cross Section) of the workpiece, which requires hoisting of the workpiece, and has high requirements for the safety and reliability of the hoisting. [0003] Due to the structural characteristics of large-scale thin-walled products, it is difficult to set up a special lifting point interface, and there is no lifting tool for lifting large-scale thin-walled parts, so when carrying out large-scale thin-walled products During the hoisting test, the hoisting is very difficult, and the safety and reliability cannot be guaranteed. Contents of the invention [0004] In view of the above problems, the present invention provides a sling for lifting large-mass thin-walled parts, the sling includes a sling...
