Technical field
This utility model relates to crane gear field peculiar to vessel, particularly to a kind of keel block.
Background technology
Keel block peculiar to vessel of the prior art, is the main lifesaving appliance of various boats and ships, various offshore platform.The arm-type boat davit of existing gravity inverted, workload is less, when number is more, need to join and overlap lifesaving appliance more, not only takes up room big, and considerably increases cost, and add the expense of C&M in installation site.The utility model patent that publication number is CN202863720U discloses a kind of arm-type boat davit of gravity inverted, including arm, mounting and lifting mechanism, described arm is connected with mounting by tumbler, described lifting mechanism is connected with boat fall, described boat fall walks around mounting, arm and floating block by assembly pulley, and described mounting and lifting mechanism are all fixedly installed above deck.
In such scheme, arm is made as one, and such arm extremely takes up room, if lifeboat is put to from lash ship body position farther out, then arm size to do very big, take lash ship space.
Utility model content
The purpose of this utility model is in that to provide a kind of link-type keel block, and arm is combined by bar linkage structure, can be put by lifeboat to position farther out, is not take up space during storage simultaneously.
Above-mentioned purpose of the present utility model has the technical scheme that a kind of link-type keel block, including mounting, mounting is provided with arm, it is characterized in that: described arm includes crossbeam, swing arm, support muscle, crossbeam head is connected to boat davit, the hinged described support muscle of afterbody, the support muscle other end is hinged on mounting；Swing arm head is hinged in the beam body of crossbeam, and afterbody is hinged on mounting and pin joint is positioned at below support muscle pin joint, and described crossbeam head is provided with pulley, and the arm body of described swing arm is provided with directive wheel.
By adopting technique scheme, crossbeam, swing arm, support muscle, mounting constitute a quadric chain, by good for support muscle length adjustment, when ensureing swing arm storage to vertical state, crossbeam is exactly in level, now no matter arm takes up room, or laying the space vacateed to new rescue boat can accomplish optimization；Swing arm is opened counterclockwise, and support muscle, owing to limiting the distance between crossbeam afterbody and mounting, supports the dynamic crossbeam of rib tape and continues to open, and crossbeam, under swing arm with self dual extension, opens speed soon, lifeboat is put distance far, and action is efficiently coordinated, and improves the lifesaving time.
Preferably, being provided with unhook link assembly between described crossbeam and swing arm, unhook link assembly includes unhook head, deckle rod, transiting rod, drive link, ajusts head and is hinged on crossbeam lower head, ajusts the hooked projection being provided with boat davit on head；Transiting rod afterbody is hinged on lower section in the middle part of crossbeam, and drive link is hinged between transiting rod head and swing arm, and deckle rod is hinged between unhook head and transiting rod.
By adopting technique scheme, this unhook assembly is automatically-unhooked along with arm puts in place, and execution efficiency is high, it is not necessary to additionally manual operation, saves rescue time.
Preferably, described transiting rod is V-arrangement, and opening is towards transmission bar side, and the pin joint of deckle rod and transiting rod is positioned at the corner of transiting rod.
By adopting technique scheme, the transiting rod of V-arrangement avoids stress and concentrates on a place, reduce transiting rod and crossbeam hinged place impact force, and make transiting rod and drive link distance closer to, it is shorter that drive link length can be done, but being because the amplification of v-shaped structure, deckle rod remains able to the swing realized by a relatively large margin, realize smoothly breaking off relations.
Preferably, described drive link is shorter in length than deckle rod.
By adopting technique scheme, principle is with similar to the above, it is possible to reduces the long risk causing deformation of drive link, simultaneously works as the effect that deckle rod amplitude of fluctuation is amplified.
Preferably, described hooked projection and unhook head are integrally cast.
By adopting technique scheme, the structure good integral strength of integrally casting, hooked projection and unhook head are not likely to produce crackle, it is ensured that safe falling lifeboat.
In sum, this utility model has the advantages that has carried out space utilization maximization by arm linkage, utilizes unhook linkage to carry out servo-actuated unhook, and execution efficiency is high, seizes rescue time.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of link-type keel block, including mounting 2, mounting 2 is provided with arm, it is characterized in that: described arm includes crossbeam 5, swing arm 3, support muscle 4, and crossbeam 5 head is connected to boat davit 6, the hinged described support muscle 4 of afterbody, and support muscle 4 other end is hinged on mounting 2；Swing arm 3 head is hinged in the beam body of crossbeam 5, and afterbody is hinged on mounting 2 and pin joint is positioned at below support muscle 4 pin joint, and described crossbeam 5 head is provided with pulley 7, and the arm body of described swing arm 3 is provided with directive wheel 10.Crossbeam 5, swing arm 3, support muscle 4, mounting 2 constitute a quadric chain, by good for support muscle 4 length adjustment, it is ensured that when swing arm 3 storage is to vertical state, crossbeam 5 is exactly in level, now no matter arm takes up room, or laying the space vacateed to new rescue boat 1 can accomplish optimization；Swing arm 3 is opened counterclockwise, and support muscle 4 is owing to limiting the distance between crossbeam 5 afterbody and mounting 2, and support muscle 4 drives crossbeam 5 to continue to open, crossbeam 5, under swing arm 3 with self dual extension, opens speed soon, lifeboat is put distance remote, action is efficiently coordinated, and improves the lifesaving time.
Wherein, being provided with unhook link assembly 8 between crossbeam 5 and swing arm 3, unhook link assembly 8 includes unhook 11, deckle rod 12, transiting rod 13, drive link 14, ajusts head and is hinged on crossbeam 5 lower head, ajusts the hooked projection 11a being provided with boat davit 6 on head；Transiting rod 13 afterbody is hinged on lower section in the middle part of crossbeam 5, and drive link 14 is hinged between transiting rod 13 head and swing arm 3, and deckle rod 12 is hinged on unhook between 11 and transiting rod 13.This unhook assembly is automatically-unhooked along with arm puts in place, and execution efficiency is high, it is not necessary to additionally manual operation, saves rescue time.
As it is shown on figure 3, transiting rod 13 is V-arrangement, opening is towards drive link 14 side, and the pin joint of deckle rod 12 and transiting rod 13 is positioned at the corner of transiting rod 13.The transiting rod 13 of V-arrangement avoids stress and concentrates on a place, reduce transiting rod 13 and crossbeam 5 hinged place impact force, and make transiting rod 13 and drive link 14 distance closer to, it is shorter that drive link 14 length can be done, but it is because the amplification of v-shaped structure, deckle rod 12 remains able to the swing realized by a relatively large margin, realizes smoothly breaking off relations.
Wherein, drive link 14 is shorter in length than deckle rod 12.Principle is with similar to the above, it is possible to reduces the long risk causing deformation of drive link 14, simultaneously works as the effect that deckle rod 12 amplitude of fluctuation is amplified.
Wherein, hooked projection 11a is integrally cast with unhook 11.The structure good integral strength of integrally casting, hooked projection 11a is not likely to produce crackle with unhook 11, it is ensured that safe falling lifeboat.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
