Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a lifting and flipping mechanism for H-shaped steel. Background Art

[0002] The H-shaped steel is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has strong bending resistance in all directions; moreover, it has the advantages of simple construction and light weight, and has been widely used. In steel structure projects, there are a large number of hoisting operations and pre-assembly operations for H-shaped steel structures; the current lifting tools mainly use a single lifting tool to maintain balanced support for the H-shaped steel symmetrically left and right, and cannot realize the flipping of the H-shaped steel. After the H-shaped steel structure is hoisted to the designated platform, it can only keep the plane upward during hoisting, and it is difficult to flip; moreover, during processing, when flipping is required, a crowbar is used for operation, the operation is complex, and it is not conducive to the stable landing of the H-shaped steel structure, which not only reduces the production efficiency, but also poses a safety risk to the operators.
