Description

A hoisting device, its hoisting method, its application, and its hoisting system

technical field

The present invention relates to a hoisting tool and its hoisting method, its application and hoisting system, more specifically, it relates to a hoisting tool tool for hoisting an object whose center is a circular through hole, its hoisting method, its application and its hoisting system .

Background technique

In machinery manufacturing, casting and other industries, for the handling of workpieces or other parts with a circular through hole in the center, spreader tooling is often used, and the integral spreader is driven by driving to move and transport the circular workpiece. However, the structure of the existing hanger for carrying annular workpieces often adopts a hinge structure that is provided with a plurality of movable joints. When using the spreader with this structure, the force on the movable joints is very large, and the joints are prone to damage. And the hanger of this hinge structure, because the rigidity deficiency of its hinge structure joint itself, when hoisting moving article, article can shake, increases its wearing and tearing, and service life is short. Moreover, when lifting heavy objects, it is very easy to fall off and cause safety accidents.

At present, when hoisting the workpiece, the hanger is often used to hook the outside of the workpiece for hoisting. When hoisting large-sized parts such as large thin-walled impeller plaster, the form of hoisting outside the workpiece is often required to increase the size of the sling. After completing the hoisting process, increasing the size of the spreader will not only increase the weight of the spreader itself, increase the cost of manufacturing the spreader, and increase the burden of the lifting process. The joints are not tight, the control process of the spreader is more complicated, the lifting process of the spreader is not reliable, and it is easy to shake, which will cause wear to the workpiece.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art above, and to provide a sling that can easily hoist workpieces with internal holes (both through holes and blind holes).
