Description
Technical field
The invention belongs to unmanned boats to lift by crane technical field, and in particular to a kind of unmanned boat automatic deploying and retracting hanging apparatus.
Background technique
Unmanned boat is a kind of novel ships and light boats, is manipulated by intelligence system autonomous navigation or someone's long-distance remote control, navigation
With nobody on ship when operation, this is and the maximum difference of someone's ship.Someone's ship and unmanned boat require to receive lash ship or from mothers
It is put down on ship, the folding and unfolding of someone's ship is relatively simple, by lifting rope is manually hung over the suspension hook on lash ship, does not need folding and unfolding lifting
Device.
Traditional folding and unfolding hanging apparatus has the following problems: needing manually, the folding and unfolding of canoe needs someone on ship to grasp manually
Make, this is at all unworkable on unmanned boat；It is inconvenient, when lifting by crane canoe by lifting rope with the suspension hook on lash ship, it is thus necessary to determine that
The center of gravity of weight is to guarantee balance and safety when lifting.Therefore traditional approach lifting needs to manually adjust the center of gravity position of suspension hook
Set, as at sea this severe condition, hull rise and fall on the waves it is indefinite in the case where, operate very difficult.At nobody
It, even more can not be by manually adjusting balance on ship；Storage is inconvenient, traditional lifting material after canoe is put down, need by
Hanging apparatus stores, and hull is limited, also puts without so multiposition, and puts and be easy to trip on deck plane or lose
It loses；Security performance not can guarantee, and traditional hoisting mechanism is linked using the simple mode such as knotting or shackle, the severe or people of environment
The carelessness of member can all shine personnel or hull into serious consequence, mounting means it is single: the installation side of traditional hoisting mechanism
Formula be all it is more single, general mounting means is unable to satisfy all hull or ship type.
And unmanned boat due on ship nobody, folding and unfolding is completely different compared with someone's ship, and folding and unfolding process is complicated, it is desirable that safety, fast
Victory, therefore, how to design one kind unmanned boat that is convenient and efficient, will not occupying hull space with automatic deploying and retracting hanging apparatus becomes this
The problem of field urgent need to resolve.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of unmanned boat automatic deploying and retracting hanging apparatus, real without artificial
