Description
Technical field
The present invention relates to a kind of ship lifesaving appliance, especially a kind of inflatable life raft frame and method of jettisoninging belong to ship
Field of engineering technology.
Background technology
Throwing type inflatable life raft is a kind of lifesaving appliance used when casualty occurs for ship for distress personnel, is put down
When be fixed in the life raft frame of ship deck, it is discharged and jettisoninged into outside water from life raft frame when using, now
Life raft discharges mixed gas from inflation steel cylinder itself is equipped with to be made its inflation shaping and bubbles through the water column, on ship and persons falling in water
It can login in life raft and be succoured.Throwing type inflatable life raft is because with taking, floor space is small, application method is easy, rescue
Fruit of coming into force is fast to wait main lifesaving appliance of the characteristics of being better than replacing his type lifeboat as modern navigation ship.The knot of life raft frame
Structure should consider storage when do not influence the routine work of ship, and can guarantee that life raft after quick release can it is accessible leave to
The water surface, or accessible can depart from after raft body is intake with life raft frame.
Existing throwing type inflatable life raft frame is in addition to base and support, and the vertical type for being alternately provided with only a limited length falls
Bar.After inflatable life raft release, the length of bar directly affects the coverage that raft casts hull aside.Particularly work as inflatable life raft
Place beam over deck is less than hull molded breadth, or when hull is jettisoninged in life raft and is provided with barrier on route, the length of bar
Corresponding lengthening must be done according to actual conditions.The bar that falls after lengthening is stood upright on inflatable life raft frame, has both hindered the visual field of crewman,
Also the characteristics of reducing inflatable life raft frame shock resistance and wind wave prevention significantly.
The content of the invention
It is an object of the invention to provide a kind of throwing type inflatable life raft frame and method of jettisoninging for lengthening distance of jettisoninging.
Invention is achieved by the following technical programs：
A kind of throwing type inflatable life raft frame, including the base being fixed on upper deck, the first rocking arm being sequentially hinged,

The rocking arm cross bar of arm bottom is hinged, and the rocking arm of the connecting rod other end is fixed clasp and is resisted against outside base cross bar, and pull bar one end is worn successively
Cross rocking arm and fix clasp and base cross bar, the pull bar other end passes through the rack cross-bar of support bottom, is supported on support；Stop pin
Successively pass perpendicularly through base cross bar and pull bar one end termination locking pull bar；It is resisted against on the downside of inflatable life raft on base, colligation system
The binding strap of system bypasses inflatable life raft, and the snare of binding strap lower end is on pull bar one end, and head line one end passes through Weak link device
It is connected with base, the head line other end is connected with deck.
Foregoing throwing type inflatable life raft frame, wherein the length ratio of first rocking arm, the second rocking arm and the 3rd rocking arm
For 1：1.7~1.9：1.05~1.15.
Foregoing throwing type inflatable life raft frame, wherein the second rocking arm shakes with the outside of the first rocking arm tie point and the 3rd
Baffle plate is respectively equipped with the outside of arm and the second rocking arm tie point.
Foregoing throwing type inflatable life raft frame, wherein between the first rocking arm, the second rocking arm and the 3rd rocking arm, the first rocking arm
It is hinged respectively by bolt and nut group between one end and base.
A kind of application method of throwing type inflatable life raft frame, comprises the following steps：
1）3rd rocking arm, the second rocking arm are pushed out successively, make it with the first rocking arm into a straight line tilted down；
2）Stop pin is first extracted, then pull bar is pulled to direction on the inside of ship side, pull bar one end departs from base cross bar, shaken successively
Arm fixes the snare of clasp and binding strap lower end, and inflatable life raft departs from base, while three rocking arms are into free state；
3）Inflatable life raft is tumbled in the presence of its deadweight along the inclined upper side of base, promotes three rocking arms to ship
Outboard is rolled down in water after opening as yi word pattern inclined ramp end to end each other, inflatable life raft along slideway.
The present invention is simple in construction, easy to use, the first rocking arm mutually hinged, the second rocking arm and the 3rd rocking arm fold after with
The inclined upper side formation four sides of base surrounds the structure of inflatable life raft so that inflatable life raft is reliablely and stablely positioned at bottom
On seat.Each rocking arm is launched into yi word pattern inclined ramp and increases distance of jettisoninging between inflatable life raft and main hull, and sends out this
It is bright to be limited by Ship Structure or other barriers.The connecting rod of inflatable life raft relieving mechanism of the present invention and Tiebar structure energy
Ensure that usually each rocking arm can be fixedly supported on base after folding.The present invention's jettisonings method when occurring casualty, only
Pull bar need to be pulled out after the stop pin on extracting pull bar, pull bar is extracted out from rocking arm clip and fake, just can be easily quick
Open each rocking arm and each rocking arm is launched into the inclined slideway of yi word pattern immediately, so that inflatable life raft is quick from slideway
Roll the entry, it is very convenient to operate, improve the probability that distress personnel is rescued safely.
