Abstract

The utility model relates to a universal device to decrease the swing of ships, comprising a return leg bracket fixed on a deck, a longitudinal arc orbit, a transverse arc orbit, longitudinal guide wheels, transverse guide wheels, a slide vehicle body, a counterweight, a pallet, etc. The restoring torque supported by a ship body which is sloped can be converted into relative motion between the slide vehicle and the two arc obits to reduce the amplitude value of roll obviously according to the slide vehicle which has the characteristic of doing centripetal motion along a radius direction pointing the circle center of the two arc obits when the slide vehicle moves on the two arc obits. The utility model can be popularized into parts, such as cooking stoves, cookers, instrument, chairs, command stations, chart house, aid couches, etc. which request swing decrease and in ships according to the design principle of the universal device to decrease swing of ships.

Description

Universal device to decrease roll of vessel

The utility model is the universal antirolling apparatus that a kind of suitable boats and ships use.

Boats and ships navigation on the sea with periodically wave motion, meeting bring a series of trouble, influence crewman's normal operation and having a pleasant journey of passenger because of waving to crewman and passenger of boats and ships.

Existing universal antirolling apparatus peculiar to vessel (Chinese patent ZL88220150,6) utilize spherosome to have that the characteristics of universal rotation and ball have the effect that reduces friction, the righting moment that is subjected to after hull is tilted is converted into the relative motion between spherosome and ball and reach subtract shake purpose but this antirolling apparatus to exist static pressure between spherosome and ball when practical application bigger than normal and cause to subtract to shake and make the defective that lags behind.

Task of the present utility model is to make a kind of simple in structure, cheap and better universal antirolling apparatus peculiar to vessel of stabilizing efficiency.

The purpose of this utility model be realize like this, universal antirolling apparatus peculiar to vessel comprises fixing four foot supports, vertically camber rail, laterally camber rail, vertically guide wheel, laterally guide wheel, coaster body, counterweight, pallet above deck, need subtract the object that shakes, comprise instrument, stove and accessory cooker, seat ... Deng, just can be placed on the pallet of this device.When pitching (is that lift up on the front and back top in axle center with the hull central, transverse axis) takes place in boats and ships under sail, four foot supports of this device and the vertical camber rail that is fixed on the support also tilt forward and back, the righting moment that four foot supports and vertical camber rail are subjected to after tilting acts on the coaster body by vertical guide wheel of coaster body lower end, because vertically guide wheel has the effect that reduces friction, make the coaster body vertically can rely on action of gravity to slide to its balance position rapidly after the inclination of camber rail, thereby make the horizontal camber rail of frame on the coaster body, counterweight and pallet still remain on original horizontality; When rolling (is the wigwag motion at center with the hull major axis) takes place in boats and ships under sail, four foot supports of this device and vertical camber rail also tilt, because the direction of vertical camber rail bevelled direction and vertical guide wheel movement in vertical state, so vertical guide wheel is slack, whole coaster body is also along with inclination, at this moment, the righting moment that hull is subjected to after tilting then directly acts on horizontal camber rail by the horizontal guide wheel of coaster body upper end, because coaster body upper end laterally guide wheel has the effect that reduces friction, make horizontal camber rail when being subjected to the hull obliquity effects, can under the action of gravity of counterweight, slide to its balance position, thereby make the pallet that is fixed on the horizontal camber rail also be in horizontality; When comprehensively waving of pitching, rolling takes place in boats and ships under sail simultaneously, the righting moment that is subjected to of hull act on simultaneously vertical camber rail, laterally the camber rail, because vertical guide wheel of coaster body is arranged, thereby the laterally action of gravity of the interoperation of guide wheel and counterweight, make pallet when being subjected to the comprehensive obliquity effects of hull, still remain on original horizontality to make the object that is placed on the pallet reduce the amplitude of waving significantly and reach the universal effect of shaking that subtracts.

The utility model because be conceived to has when pulley move on the camber rail along radius and points to the characteristics doing entad to move in the center of circle, the righting moment that is subjected to after the hull inclination is converted into relative motion between pulley and the camber rail, action of gravity by counterweight simultaneously makes pallet can remain on original horizontality when being subjected to the hull obliquity effects, so stabilizing efficiency is good, simple in structure, use also makes things convenient for.

Concrete structure of the present utility model is drawn by following embodiment and accompanying drawing thereof.

Below in conjunction with details and the service condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

This device comprise four foot supports 1., vertically the camber rail 2., the coaster body 3., vertically guide wheel 4., laterally guide wheel 5., laterally the camber rail 6., counterweight 7., pallet 8..

When pitching takes place in boats and ships under sail, four foot supports that are fixed on hull 1., being installed in vertical camber rail that 1. four foot supports go up 2. tilts forward and back too, the righting moment that four foot supports are subjected to after 1. and vertically 2. the camber rail tilts by the coaster body 3. vertical guide wheel of lower end 4. act on the coaster body 3., because vertically 4. guide wheel has the effect that reduces friction, when 2. vertical camber rail tilts, whole coaster body 3. along the longitudinal the camber rail 2. the bevelled direction slide into its balance position, thereby make horizontal camber rail that 3. frame go up at the coaster body 6., counterweight 7., 8. pallet also keeps original horizontality; When rolling takes place in boats and ships under sail, 2. 1. four foot supports of this device also tilt with vertical camber rail, since vertically the camber rail 2. bevelled direction and vertical guide wheel 4. travel direction is in vertical state, then vertically 2. 4. guide wheel gone up slack at vertical camber rail, whole coaster body is 3. also motionless, at this moment, the righting moment that is subjected to after hull tilts then directly acts on frame, and 3. laterally the horizontal camber rail 5. gone up of guide wheel is 6. in the upper end at the coaster body, because laterally 5. guide wheel has the effect that reduces friction, make horizontal camber rail 6. when being subjected to the hull obliquity effects, can rely on counterweight action of gravity 7., 6. slide into its balance position at horizontal guide wheel between, be fixed on the pallet that 6. horizontal camber rail go up and 8. still be in horizontality and make; When boats and ships are in vertical under sail simultaneously, when horizontal stroke comprehensively waves, vertical camber rail of this device 2., it is vertical that 6. horizontal camber rail is subjected to hull simultaneously, the obliquity effects of rolling, since have the coaster body 3. vertical guide wheel of lower end 4. reach the coaster body 3. the upper end horizontal guide wheel interoperation 5., and counterweight action of gravity 7., make pallet 8. in that to be subjected to hull vertical, when influencing, bank still remains on original horizontality, thereby reduced the amplitude of waving significantly and reached the universal effect of shaking that subtracts, like this, needs are subtracted the object that shakes, comprise instrument, the stove and accessory cooker, seat ... Deng, just can be placed on pallet 8. go up, can reduce hull tilts to its influence.
