Detailed Description
The utility model is further described below with reference to the following figures and specific examples.
As shown in fig. 1-3, the present invention is a schematic structural diagram of a quick retrieval and lowering device capable of lifting a plurality of life rafts, and mainly comprises a seat frame 1, a boom 2 and a winch 4.
The seat frame 1 is fixed on a ship deck and is fixed close to a ship board; a plurality of life rafts in a storage state are fixed on the edge of the seat frame 1.
The suspension arm 2 is fixed on the seat frame 1, and the improvement of the utility model is that the suspension arm 2 is hinged on the seat frame 1 through a turnover shaft device 11, and the suspension arm 2 can be overturned towards the direction outside the ship; after the dumping and turning over, most of the suspension arm 2 is positioned outside the ship.
A head pulley 3 is arranged at the end part of the suspension arm 2, and a winch 4 is arranged on the seat frame 1; a sling rope wound on the winch 4 penetrates through the head pulley 3 and is connected with a release hook 6; the release hook 6 is an automatic release hook which meets the international life-saving equipment specification.
As shown in fig. 1, the front section of the body of the suspension arm 2 is bent, and a support base 21 is arranged in the middle of the lower part of the suspension arm 2, and when the suspension arm 2 is inclined, the lower part is horizontal, and the support base 21 is pressed on a deck; the main part upper portion of davit 2 is for stretching out the davit of extra-ship, works as after davit 2 packs up, its upper portion is vertical form, saves and accomodates the space, and whole focus is in the place ahead of trip shaft device 11, when using, only need remove fixing device, davit 2 just can receive the action of gravity, falls down automatically, supporting seat 21 presses on the deck, has just accomplished preparation work, and it is extremely convenient to operate. In order to buffer the impact force when the suspension arm 2 falls freely, a buffer device is arranged in the support seat 21.
