AI Technical Summary

Technical Problem

Existing ton bag lifting equipment is difficult to adapt to ton bags of different sizes and specifications, resulting in uneven stress on the ton bags, easy tilting or material deformation during lifting, and difficulty in achieving stable horizontal placement.

Method used

A lifting device was designed that uses an adjustable hook spacing and height compensation mechanism, and a drive motor to drive a bidirectional lead screw and an adjusting screw to achieve flexible adjustment of the hook, ensuring that the ton bag remains horizontal and stable during the lifting process.

Benefits of technology

It enables the horizontal arrangement and stable placement of ton bags, improves the versatility and operational efficiency of the equipment, avoids material compression and deformation, simplifies the operation process, and reduces safety hazards.

Abstract

This invention relates to the field of ton bag stacking and lifting technology, specifically to a ton bag stacking and lifting device that facilitates arrangement. It includes a lifting frame with uprights symmetrically installed inside. Horizontal bars are slidably arranged between the uprights. Lifting crossbars are installed on both sides of the lifting frame, centered on the uprights. Each lifting crossbar has a first U-shaped frame and multiple second U-shaped frames. A first connecting rod is fixedly installed on the first U-shaped frame, and second connecting rods are slidably arranged on the second U-shaped frames. Hangers are installed at the lower ends of both the first and second connecting rods. The upper end of the second connecting rod slides through the second U-shaped frame and slidably connects to the horizontal bars. A hook is rotatably mounted on the hanger. The second U-shaped frames move horizontally along the lifting crossbars, thereby driving the second connecting rods and the hangers and hooks mounted on them to move horizontally. This, combined with the vertical movement of the horizontal bars along the uprights, allows for flexible adjustment of the distance between the hooks on both sides and the middle hook according to different ton bag sizes.
