Embodiment Construction
[0016] The present invention will be further described below in conjunction with drawings and embodiments.
[0017] Such as figure 2 and image 3 As shown, the present invention includes a life raft 1 and a special crane 20 arranged in pairs at the rear of the weather deck 10 , and the life raft 1 is fixed on the life raft frame 2 through a lashing system 3 . The life raft 1 and its lower life raft frame 2 are respectively arranged in the aisles 101 on the left and right sides of the weather deck 10 , and the special cranes 2 are respectively arranged on top corner positions on both sides of the rear part of the weather deck 10 . The life raft frame base 4 is welded and fixed on the lower side of the life raft frame 2 , and the periphery of the life raft frame base 4 is limited by the base limit frame 5 fixed on the aisle 101 .
[0018] Such as image 3 As shown, the life raft frame base 4 includes a rectangular frame 41 welded by angle steel and rollers 42 respectively ar...

The invention discloses an arrangement mode of life rafts and special cranes and a life raft frame supporting device. The arrangement mode comprises the life rafts and the special cranes which are arranged at the rear part of an open deck in pairs. The life rafts and life raft frames are correspondingly arranged in passageways of the left side and the right side of the rear portion of the open deck. The special cranes are correspondingly arranged at the top angle positions of the left side and the right side of the rear portion of the open deck. A life raft frame base is fixedly welded to thelower side of each life raft frame. The periphery of each life raft frame base is limited by a base limiting frame fixed on the corresponding passageway. According to the arrangement mode and the liferaft frame supporting device, the rotating amplitude of crane jibs of the special cranes is reduced, and precious escape time is saved for sailors; the crane jibs can be manually rotated, so that themanufacturing requirements of the special cranes are greatly lowered, and the construction cost of a ship is reduced; and when the life rafts need to be transferred to the board sides, the life rafts, the life raft frames and the life raft frame bases can be conveniently pushed to one end of the open deck by one person, and the life-saving efficiency is greatly improved.
Description
technical field [0001] The invention relates to a ship's life-saving equipment and the layout type of the life-saving equipment crane, and also relates to a life-saving raft support device added at the bottom of the life-saving raft, belonging to the technical field of ship safety systems. Background technique [0002] For all ships that implement the SOLAS (International Safety of Life at Sea) convention, the life raft arrangement must be able to be easily transferred from side to side, otherwise it must be equipped with additional life rafts. In addition, the Convention requires that within 10 minutes after the ship is in distress and sends an abandon ship signal, the life raft must carry enough rated passengers and accessories to land on the water. To meet this requirement, if figure 1 As shown, the existing ship that implements the SOLAS Convention reserves a spacious open deck 10 at the midship line position, and two life rafts 1 and life raft frames 2 are concentrated...
