Abstract

The invention relates to a foldable and telescopic combined lifting device. The lifting device comprises a main supporting rod (1), a sliding sleeve, multiple lifting hooks and multiple foldable and telescopic lifting arm mechanisms; the lifting hooks and the foldable and telescopic lifting arm mechanisms are the same in number and are in one-to-one correspondence; and the sliding sleeve is arranged on the main supporting rod (1) in a sleeving mode and is in sliding fit with the main supporting rod. The foldable and telescopic combined lifting device is accurate in positioning, simple in structure and convenient to install, the lifting requirements of inclinometer products in different specifications can be met through folding and rotating hooks and a telescopic middle rod, through experimental argumentation, the problem that lifting devices are switched due to frequently lifting of inclinometer products is solved, and rapid combination, lifting and turnover of products in different sizes can be conveniently realized. The lifting device is accurate, reliable, good in stability and convenient to adjust, and the lifting process is greatly simplified.

Description

technical field [0001] The invention relates to the field of tooling tool design, and relates to a foldable and telescopic combined hoisting device. Background technique [0002] The assembly efficiency of the helicopter's moving parts directly affects the delivery schedule of the helicopter. At the same time, as the assembly and lifting tasks of the company's automatic tilter products become more and more heavy, it is urgent to develop a lifting device that requires different types of automatic tilter hoisting. When assembling various types of automatic tilters for helicopters, the original tooling frames use different types of special hoisting devices, which are not easy to quickly switch positioning and operation, and cannot meet the rapid replacement requirements of different automatic tilters when hoisting, and at the same time occupy too many hoisting stations in the production line , affecting mass production. After developing a foldable and telescopic combined hoist...
