Lifting frame for hoisting of multiple components

Abstract

The invention discloses a lifting frame for hoisting of multiple components. The lifting frame comprises an upper frame fixedly connected with the bottom of a walking trolley on a travelling crane, a lower frame fixedly connected with a sling, and two four-connecting rod mechanisms, wherein the tops of the four-connecting rod mechanisms are hinged to the upper frame; the bottoms of the four-connecting rod mechanisms are hinged to the lower frame; the two four-connecting rod mechanisms are of the same structure and are parallelly arranged; middle connecting pieces are mounted at the middle parts of the four-connecting rod mechanisms; the middle connecting pieces are rectangular blocks with long strip-shaped sliding grooves; and hinge shafts at the bottom ends of upper connecting rods and at the top ends of lower connecting rods of the four-connecting rod mechanisms are mounted in the long strip-shaped sliding grooves of the middle connecting pieces in a sleeving manner. According to the lifting frame, swinging and shaking are prevented during the component hoisting, transfer and storage processes, all-dimensional stability is good, safety performance is high, the components are accurately placed during the transfer boxing process, operation time is saved, and working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of operating machinery and equipment, and specifically refers to a lifting frame for multi-component hoisting. Background technique [0002] The hoisting operation of the product components produced by the production workshop in the factory is all to be lifted, transported and stored one by one by the hoist on the vehicle through the steel wire rope and its suspension hook. In the process of hoisting components and their transfer and storage, the steel wire rope is a soft rope, which will cause the components to swing and shake, and the stability is poor, and the force on the steel wire rope is uneven, the hoist is easy to overload, damage, and the safety performance is poor. During the boxing process, the swinging and shaking components are difficult to align and put in, and the work efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is: to s...
