Parallel four-bar linkage is specially: pedestal 1 is installed on the deck level identical with keel block, pedestal 1 is provided with the first hinge axis 7 and the second hinge axis 8 in vertical direction, main connecting rod 2 one end are by the second hinge axis 8 and pedestal 1 fixed-link, and auxiliary connecting rod 4 one end are by the first hinge axis 7 and pedestal 1 fixed-link; The other end of main connecting rod 2 and auxiliary connecting rod 4 passes through the 3rd hinge axis 9, the four hinge axis 10 and prevents that waving pin 5 links respectively, and pedestal 1 and main connecting rod 2, auxiliary connecting rod 4, the anti-pin 5 that waves form parallel four-bar linkages like this.
The 3rd hinge axis 9 on pedestal 1 and the 4th hinge axis 10 are in the direction perpendicular to deck.
Main connecting rod 2 is provided with the crank drive shaft 13 of doing driving effect, between crank drive shaft 13 and the second hinge axis 8, part is the driving crank of main connecting rod 2, crank drive shaft 13 is hinged with drive link 3 one end, and drive link 3 other ends pass through axle drive shaft 6 fixed-link on keel block principal arm 12.
The described mechanical linkage formula anti-sway device that is applied to lifesaving keel block is two, is placed in respectively keel block both sides, synchronization action.
3, beneficial effect:
This device of mechanical linkage formula anti-sway device that is applied to lifesaving keel block of the present utility model is to have applied parallel four connecting rod principles, take keel block body as propulsion source, the passive keel block of following, in the process of routing up at keel block, any position has all guaranteed that the push rod that rubber plate face is housed is close to hull, thereby effectively reached anti-ship, protects the object that ship reduces amplitude of fluctuation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model mechanism principle figure.
The specific embodiment
Pedestal 1 is installed on the deck level identical with keel block, pedestal 1 is provided with the first hinge axis 7 and the second hinge axis 8 in vertical direction, main connecting rod 2 one end are by the second hinge axis 8 and pedestal 1 fixed-link, and auxiliary connecting rod 4 one end are by the first hinge axis 7 and pedestal 1 fixed-link; The other end of main connecting rod 2 and auxiliary connecting rod 4 passes through the 3rd hinge axis 9, the four hinge axis 10 and prevents that waving pin 5 links respectively, and pedestal 1 and main connecting rod 2, auxiliary connecting rod 4, the anti-pin 5 that waves form parallel four-bar linkages like this.
The first hinge axis 7, the second hinge axis 8, the 3rd hinge axis 9 and the 4th hinge axis 10 form four summits of parallelogram, due to the 3rd hinge axis 9 on pedestal 1, the 4th hinge axis 10 is in the direction perpendicular to deck, so with the 3rd hinge axis 9, the four hinge axis 10 and main connecting rod 2, the anti-pin 5 that waves that auxiliary connecting rod 4 connects is just all the time perpendicular to deck.Like this keel block rout up in process anti-wave pin 5 will be parallel with ship longitudinal plane of symmetry all the time, can remain on ship body one side, thereby restriction ship is to the amplitude of this side oscillation.On main connecting rod 2, separately there is the thirdly driving crank axle 13 of doing driving effect, between driving crank axle 13 and hinge axis 8, part is the driving crank of main connecting rod 2, in other words the double driving crank of doing of main connecting rod 2, driving crank axle 13 is hinged with drive link 3 one end, drive link 3 other ends pass through the 5th hinge axis 6 fixed-link on keel block principal arm 12, the propulsive effort of this link-type anti-sway device is from keel block principal arm body, during keel block upset, principal arm drives drive link 3 to move by the 5th hinge axis 6, drive link 3 pulls main connecting rod 2 by driving crank axle 13, thereby drive, prevent that waving pin 5 follows keel block, hull is mobile routing up together, the anti-pin 5 that waves can be pressed close to come out boldly all the time and follows keel block and ship is routed up, actv. has played the effect of restriction hull rocking tendency.
When keel block drives while routing up at hydraulic ram, keel block principal arm 12 drives drive link 3 by axle drive shaft 6, by driving crank axle 13, affects main connecting rod 2 to rotate around seat axle 8, thereby promote the anti-pin 5 that waves, follows that life boat 11 is parallel to be shifted out.By planned course, shown, the anti-pin 5 that waves keeps the distance of 0-116 millimeter all the time with ship side, the amplitude of fluctuation that has well stoped ship, the position of finally transferring moment is limited in possible amplitude of fluctuation 20 degree of ship in 10 degree, has reached preferably anti-object of waving.Anti-wave pin 5 fronts with countersunk-heat bolt fixedly rubber plate prevent from damaging life boat 11 surfaces.
