AI Technical Summary

Technical Problem

In the existing lifting technology, the rigging is easily worn or cut off by sharp edges and angles of the items to be lifted during the lifting process, resulting in safety hazards, and the existing protection devices cannot effectively adapt to items to be lifted with different edge shapes.

Method used

A protective device for lifting is designed, including a protective plate and a pressing strip, which has a first and a second supporting surface, both arranged at an angle, and the pressing strip extends in the first direction and is rotatable to adapt to edges and angles of different angles. The device is attached to the edges and corners before lifting, so that the rigging does not directly contact the edges and corners to avoid damage.

Benefits of technology

It effectively avoids the rigging being damaged or cut off by edges during lifting, improves the safety of lifting, and can be suitable for items to be lifted with different edges and angles.

Abstract

A protection device for hoisting is used at a corner angle formed by intersection of edges of a first surface and a second surface of an article to be hoisted, the length direction of the corner angle is recorded as a first direction, and the protection device comprises a protection plate, a first supporting surface and a second supporting surface, the first supporting face and the second supporting face are arranged in an included angle mode, the side edges of the first supporting face and the second supporting face extend in the first direction after being connected, and therefore a space where the corner angle of the to-be-hoisted object is placed is defined, and a first surface forming the corner angle is attached to the first supporting face; the pressing strip extending in the first direction is arranged on the second supporting face in the mode that the pressing strip can rotate around the axis of the pressing strip, a part of the side circumferential face of the pressing strip is a flat and straight face extending in the first direction, and the flat and straight face protrudes relative to the second supporting face so that a second surface forming the corner angle can be attached to the flat and straight face. The lifting appliance can be suitable for articles to be lifted with different corner angle shapes.
