AI Technical Summary

Technical Problem

Existing high-altitude hoisting equipment is difficult to adapt to cylindrical components of different diameters, and traditional fixing methods are prone to loosening and lack cushioning, causing components to shake and be damaged during hoisting.

Method used

It adopts an elastic telescopic airbag and a U-shaped frame with a locking mechanism. The airbag expansion and locking components are controlled by a ring piston, and the elastic straps achieve double locking, which can adapt to different diameters and prevent shaking.

Benefits of technology

It achieves adaptive locking of cylindrical components, preventing loosening and reducing swaying, protecting components from damage, and improving hoisting stability.

Abstract

This utility model relates to the field of hoisting technology, and more particularly to a double-locking mechanism for high-altitude hoisting. The double-locking mechanism includes a fixed support, on which a storage cylinder is fixedly mounted. The storage cylinder contains an elastic telescopic airbag and an annular air storage chamber, within which a slidingly connected annular piston is installed. Two symmetrically distributed U-shaped frames are fixedly mounted on the outer wall of the storage cylinder. Each U-shaped frame has a connecting rod fixedly mounted on it, and multiple elastic straps are fixedly mounted on the connecting rod. The double-locking mechanism provided by this utility model uses the annular piston to compress the gas in the annular air storage chamber, driving the elastic telescopic airbag to expand radially, adaptively filling the gap between the material and the storage cylinder, achieving stepless adjustable locking. The elastic straps on the symmetrical U-shaped frames crosswise and bind the top of the material, forming a bidirectional constraint with the airbag to prevent loosening caused by hoisting sway.
