Plug-in lifeboat hook unit with on-load unhooking function

Abstract

The invention provides a plug-in lifeboat hook unit with an on-load unhooking function. The plug-in boat hook unit adopts a whole sealing and compact plug-in boat hook body structure which comprises a lifeboat hook and a gyrorotor. A plurality of lockable steel balls are used for bearing and double springs have a function of effectively preventing accidentally unhooking and a self-pretection function, and consequently the plug-in lifeboat hook unit is novel in design, changes a traditional open-type inverted lifting hook structural form, has on-load and no-load unhooking functions, is strong in corrosion resistance, convenient to maintain and reliable in functions, can adapt to big pitching and rolling states caused by sea waves in the process of lowering a lifeboat, and can not unhook accidentally.

Description

technical field [0001] The invention relates to a boat hook device, in particular to a plug-in lifeboat boat hook device with the function of on-load unhooking. Background technique [0002] As an important tool for ship safety and lifesaving, lifeboats are mainly used in cruise ships, cargo ships, offshore drilling platforms and other occasions that require lifeboats. The lifeboat carries the means of lifesaving when a marine disaster occurs, and the lifeboat hook is responsible for the function of releasing the lifeboat. Its working reliability and safety play a key role in the safety of personnel when the lifeboat is lowered. [0003] For a long time, due to the casualties caused by the lifeboat release process, the requirement for on-load release of the lifeboat hook has become a concern and concern in the industry about the safety of the lifeboat on-load release hook. Faced with this problem, the International Maritime Organization (IMO) Convention on the Safety of Lif...

Problems solved by technology

In order to prevent accidental decoupling of the lifeboat hook during hoisting of the lifeboat, an anti-detachment mechanism needs to be installed to block the exit of the hook. When the waves cause the big ship to shake at a large angle, it is easy to cause accidental decoupling of the lifeboat hook midway, causing casualties on board

[0005] The traditional open-type boat hook cannot design the boat hook device into a closed structure, which inevitably causes seawater salt spray corrosion problems. If the inherent limitations of the open-type boat hook can be avoided, a new hook connection method is used to design the boat hook as The closed structure improves the safety and reliability of the hook, improves the anti-rust and corrosion resistance of the hook, reduces maintenance costs, and increases the service life of the hook
