Abstract

The invention discloses a folding crane. The folding crane comprises an unfolding drive mechanism, a frame body mechanism and a suspended loading mechanism mounted on the frame body mechanism. The frame body mechanism comprises first frame bodies, second frame bodies and third frame bodies. The unfolding drive mechanism comprises an unfolding electric winch, an unfolding steel wire rope and an unfolding guide wheel. When the crane is unfolded, plane structures of the two first frame bodies are attached, slope structures of the first frame bodies are attached to slope structures of the second frame bodies, the first frame bodies and the second frame bodies are in a vertical state, and plane structures of the third frame bodies are attached to the plane structures of the second frame bodies.Objects are subjected to suspended loading through the suspended loading mechanism, under the effect of the unfolding drive mechanism, the automatic unfolding function after the whole crane is foldedis achieved, unfolding is convenient, meanwhile, under the effect of a closing drive mechanism, automatic folding and storing of the whole crane are achieved, the occupied space is small, the crane can be conveniently stored, transported, moved and transferred, and the corresponding cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a folding crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. The existing cranes as a whole cannot be folded and stored, resulting in a large space occupied by the crane when stored, which is not conducive to the rational use of space, and the transportation and transfer of the crane are quite troublesome and costly. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a folding crane. The structure of the present invention is ingeniously designed to realize the overall folding and storage of the crane, which occupies a small space and facilitates the storage, transportation, movement, and transfer of the crane. Easy to fold and unfold. ...
