Problems solved by technology

[0002] In the prior art, the conventional hook structure cannot be hoisted and transported smoothly under turbulent and deep-sea (swaying and undulating) conditions, and cannot offset the impact caused by load or turbulence, and in low temperature environments, the cold shock requirements for materials higher
Under deep sea conditions and turbulent conditions, conventional hooks are subject to greater impact, which affects the stability and safety of lifting, and will reduce the service life of lifting equipment

Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0023] figure 1 Shows the structure diagram of the hook structure of this embodiment, including: hook 1, outer shell 2, buffer spring group 3, spring seat 4, lower nut 5, suspension rod 6, suspension seat 7 and anti-shock spring group 8 .

[0024] Wherein, the hook 1 and the outer shell 2 are fixedly connected, in this embodiment, it is specifically a screw connection, the outer shell 2 is cylindrical in shape, and its outer wall has threads, and the hook 1 is screwed to the outer shell 2 through the threads. connected together. Mounting holes are provided on the upper and lower bottom surfaces of the outer shell 2 , and the suspension rod 6 penetrates into the mounting holes and forms a flexible connection with the outer shell 2 .

[0025] The upper end of the susp...

Abstract

The invention provides a hoisting device and a hoisting hook structure of the hoisting device. The lifting hook structure comprises a hoisting hook, an external shell fixedly connected with the lifting hook, a hoisting rod fixedly connected with a hoisting seat, a lower nut fixedly connected with the hoisting rod, and a buffer spring seat arranged between the external shell and the lower nut, wherein the hoisting hook is used for pulling the external shell when being hoisted so as to extrude the buffer spring set, and the buffer spring set is used for transmitting the stress to the hoisting rod and the hoisting seat through the lower nut. The bump can be counteracted and reduced, and the cargo bump condition under deep sea working condition can be reduced, the stability and security are improved, and the cold blanking requirement is reduced.

Description

technical field [0001] The invention relates to a hoisting device and its hook structure, in particular to a hook structure with a buffer spring group and a hoisting device including the hook structure. Background technique [0002] In the prior art, the conventional hook structure cannot be hoisted and transported smoothly under turbulent and deep-sea (swaying and undulating) conditions, and cannot offset the impact caused by load or turbulence, and in low temperature environments, the cold shock requirements for materials higher. Under deep-sea working conditions and turbulent working conditions, conventional hooks are subject to greater impact, which affects the stability and safety of lifting, and will reduce the service life of lifting equipment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hoisting device and its hook structure, which can offset and reduce turbulence and cargo turbulence under deep-se...
