Description

Technical Field

[0001] The utility model belongs to the technical field of lifting devices, in particular to a lifting hook used for building construction. Background Art

[0002] During the construction process, a large amount of materials and equipment need to be transferred in space, and the transfer process requires the cooperation of lifting equipment, which mainly includes motors, hangers, ropes and hooks. The reliability of lifting equipment directly determines the safety of equipment and personnel on the construction site, and the performance of the hook plays a key role. Especially at the construction site, workers' safety awareness is relatively weak, and the hook is used frequently every day, so the quality and reliability of the hook deserve special attention.

[0003] Based on the above, the inventors found that the existing hooks have the following shortcomings:

[0004] 1. The anti-dropping piece of the hook is closed by elasticity, which is easy to fail in elasticity during long-term use. It is not convenient to add a threaded column and a threaded barrel at the opening position of the hook to make the threaded barrel engage and move to achieve closing and opening.

[0005] 2. The hook rope hole and the hook are integrated, so they cannot be replaced separately after wear and damage. It is not convenient to install a bearing seat on the top of the hook and install a rope column on the bearing seat to achieve separate replacement after damage.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a hook for building construction is provided, in order to achieve a more practical purpose. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a hook for construction, so as to solve the problem that the existing hook anti-dropping plate is easily elastically failed during long-term use through elastic sealing, and it is inconvenient to install a threaded column and a threaded barrel at the opening position of the hook to make the threaded barrel mesh and move to achieve closing and opening; the hook rope threading hole and the hook are integrated, resulting in the inability to replace them separately after wear and damage, and it is inconvenient to install a bearing seat on the top of the hook and install a rope column on the bearing seat to achieve separate replacement after damage.
