Unexpected slide preventing type double-layer raft frame

Abstract

The invention relates to an unexpected slide preventing type double-layer raft frame. The unexpected slide preventing type double-layer raft frame comprises an inclined base, a fastening rope, gear levers and a hydrostatic pressure releaser, and further comprises a limiting rod, wherein the middle lower parts of one or more gear levers are hinged to the inclined base, and are uniformly distributedin an inclination direction of the inclined base; the upper parts of the gear levers are in puling connection onto the inclined base by the fastening rope wound and tightened on a life raft via the hydrostatic pressure releaser; the limiting rod is arranged on the lower part of the inclined base in a penetrating mode in a direction parallel to the inclination direction of the inclined base, and can be in a movable drawing and pulling state in the inclination direction of the inclined base; and the limiting rod is movably arranged in a limiting hole in the lower part of each gear lever in a penetrating mode. The unexpected slide preventing type double-layer raft frame is simple in structure, is stable and convenient to use, can effectively prevent the problem that the life raft drops unexpectedly or cannot be released through faults, and improves use safety performance.

Description

technical field [0001] The invention relates to ship equipment, in particular to a double-layered raft frame for preventing accidental slipping. Background technique [0002] At present, the double-deck life raft frame is widely used in ships that are in operation and construction, which saves space and is convenient to arrange. According to market feedback, life raft accidents often occur due to corrosion and aging of steel wire ropes or failure of hydrostatic pressure release devices during ship operation. Throwing away, the disposable life raft cannot be recovered after falling into the water, causing economic loss to the ship. At the same time, there is also a failure of the hydrostatic pressure release device, which prevents the life raft from being released, which poses a serious safety hazard. Contents of the invention [0003] The invention provides a double-layered raft frame with a simple structure, stable and convenient use, which can effectively prevent the lif...
