The back-retraction fin stabilizer retracting and extending mechanism is characterized in that an adjusting plate with an adjustable thickness is assembled on a front vertical plate of a fin box; the adjusting plate is correspondingly sleeved on one end of a guide sleeve and is in contact with one end of a slide sleeve in the working position of the fin; another adjusting plate with an adjustable thickness is assembled on the rear vertical plate of the fin box on the other end of the guide sleeve and is in contact with the other end of the slide sleeve in the fin retracting position; and a radical spherical plain bearing is arranged on a retracting and extending connection rod; a rotating arm has a combination structure; and a split-type dustproof ring is adopted. The back-retraction fin stabilizer retracting and extending mechanism is suitable for various back-retraction fin stabilizers.

Description

Folding and unfolding mechanism of back-unfolding stabilizing fin device
Technical field:
The present invention relates to a kind of equipment that reduces the ship of rolling, particularly a kind of equipment that uses hydrofoil to act on the motion of the ship of water surface minimizing on every side.
Background technology:
Ship is in ocean navigation, to produce rolling motion under wind wave action, the rolling meeting of boats and ships makes navigability reduce the injured vessel body structure, influence equipment, instrument is normally moved, goods displacement or bump are damaged, passenger crewman is swooned, serious rolling also may cause danger, to combat vessel may influence or even the forfeiture fighting capacity, in order to reduce ship rolling, the dealer adopts various methodologies, as bilge keel, antirolling tank, subtract and shake gyro, subtract and shake weight and stabilizer or the like and subtract the equipment of shaking; Increase day by day along with development of technology and high speed ship quantity, also since the stabilizing efficiency of stabilizer and the speed of a ship or plane on naval vessel be directly proportional, stabilizer has become the visual plant that higher speed of a ship or plane naval vessel reduces to wave and improve navigation performance, existing stabilizer form is varied, conclude and get up to mainly contain two big classes, be non-extendible and extendible, and based on extendible, extendible then comprises collapsible, telescopic and partly telescopic, wherein very fast with collapsible development, previous collapsible stabilizer mostly is preceding receipts formula structure, but because the back folding type structure has and can reduce running resistance, fin efficient height, fin can be laid in the better position of hull streamline, naval vessel to improve stabilizing efficiency, maintenance cost is low, advantages such as fin case size is little, the back folding type fin stabilizer obtains large development in recent years;
The key components of back folding type fin stabilizer are its jacks, the prior art scheme of this mechanism is to include the folding and unfolding oil cylinder, the fin case, sliding sleeve, the folding and unfolding connecting rod, pilot sleeve, gyro-rotor and catch gear etc., the folding and unfolding oil cylinder is located in the pilot sleeve, sliding sleeve can be made axial motion on pilot sleeve, folding and unfolding oil cylinder and pilot sleeve be installed in the fin case and and the planking solid welding, the angle of designer between the folding and unfolding connecting rod line of centers and the fin axis of emitting set one " from the locking angle ", the friction force that should the axial force that act on the sliding sleeve be produced less than diametral load from the locking angle, sliding sleeve can self-locking, thereby it is motionless to make fin remain on control position; The above-mentioned friction force value of setting up from the locking angle is subjected to all multifactor impacts and changes, when from the locking angle hour, the sliding sleeve self-lock ability is strong, the organization cylinder starting resistance is big, it is then opposite when the locking angle is big, existing fin stabilizer jack, mostly value is 5 ° of left sides, right, this value is to be contacted with sliding sleeve by fin case overhead gage to define, and baffle plate is therefore solid welding is at fin case riser,, the minimum of existing structure is from the locking angle, be baffle plate with after sliding sleeve contacts, the angle between the folding and unfolding connecting rod line of centers and the fin axis of emitting is " definite value ", and it can't adapt under all multifactor impact conditions, device can be selected preferable minimum from the locking angle, thereby bring negative effect for the function of fin, on this external existing structure, also there is the technical matters that remains to be improved in aspects such as its working service and technology.
Summary of the invention:
Technical matters to be solved by this invention provides a kind of improved folding and unfolding mechanism of back-unfolding stabilizing fin device, and it can make the minimum of jack can select optimum value on demand from the locking angle, shakes performance to guarantee fin control position and corresponding good subtracting.
The technical scheme that the present invention solves the problems of the technologies described above employing is: folding and unfolding mechanism of back-unfolding stabilizing fin device, this mechanism includes the folding and unfolding oil cylinder, the fin case, sliding sleeve, the folding and unfolding connecting rod, pilot sleeve, gyro-rotor and latch assembly, oil cylinder drives through propelling rod and is connected with sliding sleeve, the sliding sleeve endoporus is equipped with pilot sleeve and is bearing fit, sliding sleeve is connected with an end of folding and unfolding connecting rod, the folding and unfolding connecting rod other end is connected with gyro-rotor, gyro-rotor is provided with the folding and unfolding rotating shaft of fin, be characterized in: on the front vertical plate of fin case, be assembled with the adjustable adjustment plate of thickness, this adjustment plate correspondence is set in an end of pilot sleeve, control position at fin, one end in contact of this sliding sleeve has this adjustment plate to be formed with from the locking angle, be assembled with the adjustable adjustment plate of another thickness on the back vertical plate of fin case, this adjustment plate correspondence is set in the other end of pilot sleeve, in the income position of fin, an end in contact of this sliding sleeve have this another adjust plate.The self-locking position that fin is received or put can be by the thickness adjustment of adjusting plate, and is preferable from locking angle value to obtain.
The folding and unfolding connecting rod is provided with plain radial bearing, and gyro-rotor is compound type, and dust ring adopts the subdivision structure.
The present invention adopts the adjustment plate structure that can adjust thickness, the minimum that makes folding and unfolding mechanism of back-unfolding stabilizing fin device is from the locking angle, can be according to the naval vessel, the design condition of fin and corresponding navigation operating mode, select optimum value, with simple structural element conversion, can obtain preferable or best subtracting and shake performance, plain radial bearing structure of the present invention, can obviously improve the carrying condition of each moving member, prolong the service life of member, the combined type rotary body can obviously improve the manufacture craft of big part, part dust ring structure, fundamentally change conventional confguration and need dismantle the time-consuming operation of complex combination part, improve the maintenance condition of mechanism greatly.
