Description
Technical field
The utility model is related to a kind of built-in expansion boat davit.
Background technology
Lifeboat belongs to crash equipment important on ship, is used for sea escape, lifeboat need when unused
Fix on boat davit aboard ship, and can be put on sea for crewman's escape in clutch.Conventional boat davit needs
Space on more ship is taken, therefore reduces the storage quantity of boat davit and lifeboat, the number that can be succoured is reduced；And
And the telescopic arm of boat davit by space on ship due to being limited in the past, extension elongation is not long, causes the people on lifeboat can not
The rapid remote scene of the accident；The necessary hot line job of simultaneously conventional boat davit, once occurring peril on ship, causes boat davit
When not powering, the arm of boat davit just can not be allowed to stretch release lifeboat, the escape of crewman is have impact on.
The content of the invention
The purpose of this utility model be to overcome it is above-mentioned it is not enough there is provided one kind to take space on ship less, extension elongation compared with
It is long, and the built-in expansion boat davit that can be used in power failure state.
What the purpose of this utility model was realized in：
A kind of built-in expansion boat davit, it includes support frame, and support frame as described above bottom is provided with a slide rail, slide rail and set
Have arm, the arm is telescopic hoist boom, it by first segment arm, second section arm, Section three arm this three save and constitute, wherein
First segment lifting arm sleeve is in second section arm outer wall, and second section lifting arm sleeve is outside Section of three arm, and the first segment arm
Roller, the first segment arm and second are provided between second section arm and between second section arm and Section of three arm
Promotion oil cylinder is provided between section arm and between second section arm and Section of three arm, and the bottom of Section of three arm is consolidated
Surely have and hydraulic accumulator is additionally provided with suspension hook, support frame as described above, the hydraulic accumulator is with promoting the cylinder body of oil cylinder to connect.
Compared with prior art, the beneficial effects of the utility model are：
The arm of this built-in expansion boat davit is set to telescopic three sections, can increase boat davit and lifeboat
Quantity is deposited, while not increasing on ship on the premise of space-consuming, the extension elongation of lifeboat is added, lifeboat can be made
On people it is rapid away from the scene of the accident；The oil cylinder of simultaneous retractable arm is also connected with hydraulic accumulator, when boat davit is not powered, can
So that pressure oil therein is discharged into oil cylinder with accumulator, promotes oil cylinder to stretch out arm, just can guarantee that crewman normally escapes.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model built-in expansion boat davit.
Fig. 2 is Fig. 1 top view.
Wherein：Support frame 1, slide rail 2, first segment arm 3, second section arm 4, Section of three arm 5, roller 6, promotion oil cylinder
7th, suspension hook 8, hydraulic accumulator 9.
Embodiment
Such as Fig. 1 and Fig. 2, the utility model is related to a kind of built-in expansion boat davit, and it includes support frame 1, the support
The bottom of frame 1, which is provided with a slide rail 2, slide rail 2, is provided with arm, and the arm is telescopic hoist boom, and it is by first segment arm 3, second
Save arm 4, Section three arm 5 this three section to constitute, wherein first segment arm 3 is enclosed on the outer wall of second section arm 4, second section arm 4
It is enclosed on outside Section of three arm 5, and between the first segment arm 3 and second section arm 4 and second section arm 4 and the 3rd
Be provided with roller 6 between section arm 5, roller 6 be used to allowing Section of three arm 5 and second section arm 4 can with sliding extension, described the
Promotion oil cylinder 7 is provided between one section arm 3 and second section arm 4 and between second section arm 4 and Section of three arm 5, and
And the bottom of Section of three arm 5 is fixed with suspension hook 8, suspension hook 8 is used to hang to be additionally provided with hydraulic pressure on lifeboat, support frame as described above 1
Accumulator 9, the hydraulic accumulator 9 is with promoting the cylinder body of oil cylinder 7 to connect, and hydraulic accumulator 9 is one in hydropneumatic system
Energy savings device is planted, it stores pressure oil, when needed, pressure oil, which is thrown into promotion oil cylinder 7, promotes three to save arms
Stretch out.
