Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a clamp for hoisting section steel. Background Art

[0002] Ship steel and plates are used to construct the ship's inner and outer plates, platforms, decks and bulkheads. Steel is an important part of the ship's hull structure, providing lateral and longitudinal support for the hull and ensuring the stability of the hull structure. Due to its low specific gravity and good processing performance, ship steel can reduce the weight of the ship and improve its efficiency. In the hull structure, the weight of steel usually accounts for about 12% of the total weight of the hull structure, but the amount of raw materials and steel welds accounts for more than 50%.

[0003] When steel sections are in use, they generally need to be lifted by a practical lifting device for easy installation, and clamps are generally required to assist in lifting during lifting. Therefore, some people have designed steel section lifting clamps, such as the Chinese utility model patent with announcement number CN219906686U, which specifically discloses a steel section lifting device.

[0004] However, in actual use of the clamps used for lifting the steel section, people will find that when installing the clamps, the clamps need to be separately clamped on the steel section, and then passed through the lifting rope for lifting. However, since the clamps are separate, it is difficult to ensure that the two clamps are aligned with each other during installation, and in this lifting method, the lifting rope is easy to move in the ear hole of the lifting ear during lifting, resulting in unstable lifting.
