Description
Technical field
The present invention relates to a kind of equipment for reducing ships and light boats rolling motion, especially a kind of back folding type fin stabilizer.
Background technique
Stabilizer has become higher speed of a ship or plane naval vessel and reduces the important equipment for waving and improving navigation performance, existing stabilizer
Form is varied, and being summed up mainly has two major classes, i.e., non-extendible and extendible, and based on extendible, and extendible
Then include it is collapsible, telescopic and half is telescopic, wherein very fast with collapsible development, previous collapsible stabilizer was mostly preceding receipts
Formula structure, but can reduce that ship resistance, that fin is high-efficient, fin can be laid in naval vessel hull streamline is preferable since back folding type structure has
Position is to improve the advantages that anti-rolling effect, maintenance cost are low, fin case size is small.
Back folding type fin stabilizer is obtaining large development in recent years.For back folding type stabilizer, after fin takes in fin case,
Under gravity, fin may skid off outward, at this point, the left and right direction of the fin skidded off can exceed the beam (outboard), downward meeting
Baseline beyond ship, to influence ship running safety, such accident occurs in order to prevent, in back folding type stabilizer, works as fin
When in zero-bit, ad hoc stop mechanism need to be used, fin lock is no longer skidded off into accident in fin case；Fin stabilizer is in
When working condition, water flow produces the moment of resistance rotated to ship stern to executing agency, makes the trend recycled in the oriented fin case of fin, needs
Using ad hoc stop mechanism, it ensure that fin is in releasing state always.
Back folding type fin stabilizer folding and unfolding stop mechanism is mainly by retaining mechanism 1, revolving body 2, pilot sleeve 3, cunning at present
Set 4, folding and unfolding connecting rod 5, distance rod 6, folding and unfolding oil cylinder 7 and thrust block pad 8) composition, as shown in Figure 1, constituting slider-crank mechanism.
When needing to receive fin, the rod chamber oil inlet of folding and unfolding oil cylinder 7 moves piston rod to stem, and passes through piston rod two sides
Distance rod 6 push sliding sleeve 4 to move along a straight line along pilot sleeve 3, pass through the traction of folding and unfolding connecting rod 5, drive the equal components of revolving body 2
It is rotated to ship stern direction, so that fin is taken in fin case.Jack is lived using retaining mechanism lock 1, overcomes and skids off power, make fin always
In income state.Put fin process on the contrary, folding and unfolding oil cylinder rodless cavity oil inlet, make piston rod to ship stern direction move drive revolution
Body, crosshead are rotated to stem direction, so that fin is released fin case.Folding and unfolding mechanism of back-unfolding stabilizing fin device and locking machine at present
Structure, using non-standard de-sign, its structure is complicated, and part processing precision is high, and assembly difficulty, the manufacturing cycle is long, economical poor, no
It is used in equipment suitable for extending to low cost.Meet domestic market fast pace manufacturing cycle, low cost to research and develop
Ship stabilization fin apparatus folding and unfolding stop demand, is badly in need of the folding and unfolding stop mechanism that a kind of structure is simple, at low cost.
Summary of the invention
In order to solve the problems existing in the prior art, the present invention proposes a kind of back folding type fin stabilizer folding and unfolding and stop machine
Structure, the present invention make full use of the design feature of components itself in design, as folding and unfolding oil cylinder earrings during folding and unfolding from
To the effect for driving rotary disk, while when device receives, earrings itself step is utilized to carry out stop；And by lengthening revolution
The length of disk cantilever reduces the pressure that stop mechanism check plate is born, improves the reliability of product, wherein folding and unfolding oil cylinder and stop
Organization cylinder uses the engineering cylinder of standard, and the manufacturing cycle is short, makes that at low cost, versatility is stronger certainly, and passes through design folding and unfolding
Oil cylinder and stop mechanism oil cylinder stroke so that realize the adjustment of folding and unfolding angle and lock/unlock angle easily.
To achieve the above object, the technical scheme is that a kind of back folding type fin stabilizer folding and unfolding and stop mechanism,
With a jack, one is used for the stop mechanism of stop jack, at least has a receipts in the jack
It drains the oil cylinder, folding and unfolding oil cylinder is hinged on cylinder installation seat by shaft, can horizontal hunting, folding and unfolding in cylinder installation seat by shaft
The piston rod front end of oil cylinder connects the cantilever mechanism of rotary disk by oil cylinder and rotational pin one, is driven and is turned round by folding and unfolding oil cylinder
Disc spins go to rotary disk and put fin position or receipts fin position；At least there is a check plate, check plate in the stop mechanism
It is hinged in stop mechanism pedestal by check plate rotational pin, check plate rear upper end passes through stop oil cylinder rotational pin and stop oil
The piston rod of cylinder is hinged, and stop oil cylinder is connected on stop mechanism pedestal by stop oil cylinder free bearing, is stopped by the driving of stop oil cylinder
Movable plate overturning, the movement of disc spins or folding and unfolding oil cylinder is turned round for stop.
Further, the folding and unfolding oil cylinder by shaft and bearing hinge connection on cylinder installation seat, bearing and shaft end face it
Between be equipped with adjustment ring, cover board and lubricator cup are equipped with above bearing.
Further, it is equipped with adjustment block one between the check plate in the cantilever mechanism and stop mechanism of the rotary disk, passes through
Adjustment block one adjusts rotary disk and is put into parallactic angle degree.
Further, adjustment block two is set between the check plate and oil cylinder rear end, adjusts and turns round by adjusting block two
Disk receives the angle of position.
Further, the stop mechanism is mainly by stop oil cylinder, stop oil cylinder free bearing, check plate rotational pin, stop oil cylinder
Rotational pin, adjustment block three, check plate, stop mechanism pedestal and lubricator cup composition.
Further, adjustment block three is equipped between the check plate lower end surface and stop mechanism pedestal, it is thick by adjusting block three
The stroke of degree and stop oil cylinder, so that check plate reaches upper lock-bit or unlocking position.
Check plate when the contraction of folding and unfolding cylinder piston rod, which drives rotary disk to rotate to, puts fin position, in the stop mechanism
The cantilever mechanism of rotary disk is withstood, to prevent to produce the moment of resistance rotated to ship stern to executing agency because of water flow, makes fin band
The trend recycled in the dynamic oriented fin case of rotary disk.
When the piston rod of folding and unfolding oil cylinder stretches out, and revolution disc spins is driven to go to receipts fin position, stopping in the stop mechanism
Movable plate withstands the oil cylinder of folding and unfolding oil cylinder, and fin is prevented to skid off outward under the effect of gravity, and fin is made to drive the oriented fin case of rotary disk
The trend of interior recycling.
The beneficial effects of the present invention are:
Folding and unfolding stop mechanism of the invention compares with existing folding and unfolding stop mechanism:
1. in structure:
A) compact-sized simple, relative to current folding and unfolding stop mechanism, weight reduces 35%；
B) main parts size uses standardized product, and relative to current folding and unfolding stop mechanism, purchase cost reduces 50%.
2. functionally:
A) by designing different folding and unfolding oil cylinder strokes, thus it is possible to vary the folding and unfolding angle of device；
When b) being put into, using fixed rotary disk cantilever mechanism, thus overcome water flow to device generate to ship stern
The resistance torque of rotation；
When c) receiving, using fixed folding and unfolding oil cylinder, to avoid fin that from skidding off outward under the effect of gravity.
