Specific embodiment

With reference to the accompanying drawings, this utility model is further described below.

The utility model discloses a kind of telescopic life raft suspension bracket, it is different from prior art and is：It includes one Horizontally disposed arm 1, arm is the primary load bearing structure that this fall puts device, relies on the structure that arm stretches out to can achieve lifesaving Raft is pushed out to the functions such as outboard by inboard；One end of this arm 1 is in hanging shape, is provided with an arm front end and slides at arm 1 free end Wheel 2, arm 1 other end is provided with head sheave 3 after an arm, and before cable wire 4 one end bypasses above-mentioned arm, head sheave 2 is connected with coaster 4, After cable wire 4 other end bypasses above-mentioned arm, head sheave 3 is connected with the reel 6 of hoister winch 5, and hoister winch 5 is the master of folding and unfolding raft Want part, by the guiding of head pulley gear, control the folding and unfolding of steel wire rope on raft winch to reach the purpose of folding and unfolding raft；Raising The side of winch 5 is provided with hydraulic power unit 7, and the inlet end of this hydraulic power unit 7 is connected with accumulator 8, the outlet side of hydraulic power unit 7 with Telescopic oil cylinder 8 at arm 1 connects, and arm 1 is made up of main arm and secondary arm, and telescopic oil cylinder 8 is arranged in main arm, and master hangs The expansion link that arm 9 passes through telescopic oil cylinder 8 is connected with secondary arm 10, and secondary arm is stretched under the driving of telescopic oil cylinder 8 in main arm Condense shifting, be provided with stopping means 11 at the secondary arm 10 of head sheave 2 lower section before arm, stopping means are used to prevent raft raising A kind of excessive safety.

In the specific implementation, it is additionally provided with a sticking device 13 at coaster 4.

Operating procedure is as follows：

Decentralization raft (electric power), when hanging life raft, first removes the binding apparatus of life raft, switches on power, and starts hydraulic pump Stand, open button box, take out remote control knob and press the knob of lifting mechanism, roll tightly cable wire.Press raising knob, until raft from Open deck and can avoid enough release when barrier, then direction of operating valve one is so that raft can release outboard position Put.Raft is opened, and occupant steps on raft.Operator pull the brake of remote-control handle release mechanism lifting mechanism, and raft will rely under deadweight It is down to the water surface, then automatic release hook is opened, raft just can sail out of lash ship.

Reclaim raft, operator lifts winch weight above deck, take out wind, the Kong Zuoji of insertion winch wind is suitable Hour hands rotate (right machine rotates counterclockwise), so that decentralization release hook, release hook transfers in life raft personnel always lifesaving On raft hook, operator press raising button simultaneously, are raised to above deck until life raft rises, then direction of operating valve one, Raft is received deposit position, operator are left behind remote-control handle or lift winch weight and slowly drop and put raft to deck, when occupant is complete Portion is fixed raft in deposit position after leaving raft.

Dead electricity situation transfers raft, after the binding apparatus removing raft, opens stop valve two, operator take out wind, The insertion hand delthyrium of winch rotationally clockwise, extremely can avoid turning round obstacle height, release three of then leaving behind by raising raft Square ring (emergent relief valve 1 is opened, and while arm is released, pulls remote control rope, the brake of release mechanism lifting mechanism), pushes away raft Go out outboard, raft is opened, occupant starts to step on and takes advantage of.Leave behind decline handle, raft relies on the gravity of itself to drop to the water surface, automatic release hook Open, raft sails out of lash ship.

Above content be with reference to specific preferred implementation further detailed description of the utility model it is impossible to Assert that this utility model is embodied as being confined to these explanations above-mentioned.Common skill for this utility model art For art personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should It is considered as belonging to protection domain of the present utility model.
