AI Technical Summary

Technical Problem

Traditional hoisting supports cannot flexibly adapt to the hoisting needs of objects of different sizes, and are bulky when not in use, making transportation and storage inconvenient. Existing adjustable supports are complex in structure, costly, difficult to maintain, and cumbersome to adjust.

Method used

The folding auxiliary support adopts a triangular truss structure, and uses a winch to drive the steel wire to synchronously control the unfolding and retraction of the boom assembly. Combined with the elastic force of the clamping assembly, it provides dynamic balance, realizing rapid adjustment and stability of the boom.

Benefits of technology

The bracket has been significantly reduced in size when not in use, making it suitable for the rapid hoisting of objects of different sizes. It is easy to operate and improves the stability and safety of the hoisting process.

Abstract

This utility model relates to the field of hoisting technology, and in particular to a folding auxiliary support for hoisting operations. The folding auxiliary support for hoisting operations includes a base plate, with triangular trusses installed on both sides of the base plate. A rotatably connected boom assembly is installed on the same side of each of the two triangular trusses. A winch for retracting / unretracting the boom assembly is installed on the base plate. Two symmetrically distributed clamping assemblies are installed on each triangular truss. The folding auxiliary support for hoisting operations provided by this utility model can completely rotate and retract the boom assemblies on both sides into the storage cavity on the inclined beam of the triangular truss by winding up the steel wire with the winch. This design significantly reduces the volume of the support when not in use, greatly facilitating transportation and storage, and is especially suitable for working environments with limited space. Furthermore, a single winch can synchronously and smoothly control the unfolding angle of the boom assemblies on both sides, and the adjustment process is simple to operate, quickly adapting to the hoisting needs of objects of different sizes.
