Abstract
The utility model provides a passive anti-swing device for a ship-mounted crane, which is characterized by comprising a base, a swing mechanism, a hinge, a hydrocylinder, a damping hole and an energy accumulator; under the effect of drag force applied by a ship-mounted crane hook and through expanding and contraction of the piston rod of the hydrocylinder, the rotation of the hydrocylinder relative to the swing mechanism, and the rotation of the swing mechanism relative to the base, the passive anti-swing device for the ship-mounted crane can move in the space along with the crane hook, and the damping effect of the damping hole can reduce the swing of the crane hook, so that the passive anti-swing effect is achieved. The device can effectively reduces the influences of swing of the ship-mounted crane hook on lifting operation, and improve the safety and efficiency of the ship-mounted crane in lifting operation.
Description
Technical field
The invention discloses a kind of deck crane passive type anti roll device, belong to the anti-technical field of shaking of hoisting crane.
Background technology
Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, claims again crane, belongs to material carrying machine.Conventionally, elevator machinery is by lifting mechanism (making load up-and-down movement), operating unit (elevator machinery is moved), luffing mechanism and swing type mechanism (making load make parallel motion), add metallic magnetism, engine installation, handles control and necessary auxiliary device combines.The work characteristics of hoisting crane is to do intermittent, cyclicity motion, a working cycle comprises: load-engaging device is mentioned load from getting thing, is then moved horizontally to appointed place and falls load, then carries out counter motion, make load-engaging device reposition, to circulate next time.In general, hoisting crane hangs load by steel rope, suspension hook, by lifting mechanism, carries out lifting, by luffing mechanism and swing type mechanism, carries out parallel motion.Because steel rope belongs to compliant member, when carrying out luffing, gyroscopic movement, load will be made simple harmonic motion, and this can increase the time of task difficulty and working cycle.Particularly for deck crane, impact due to Marine Environment Factors such as wind, wave, streams, boats and ships can produce rolling, pitching, yawing, swaying, surging, hang down and swing six-freedom motion, and this has just more aggravated waving of load, when sea situation is severe, almost cannot carry out operation.For hoisting crane, hang thing and wave problem, adopt at present conventionally Maryland rigging mechanism, comprehensive compensating device to solve, but its mechanism and control all more complicated.
Summary of the invention
In order to overcome the weak point in background technology, the present invention proposes a kind of deck crane passive type anti roll device.
In order to achieve the above object, the technical solution used in the present invention is:
A deck crane passive type anti roll device, is characterized in that: this device comprises pedestal, swing type mechanism, hinge, hydraulic ram, damping hole, energy storage.Pedestal is fixed on deck correct position according to deck crane deployment scenarios aboard ship, and pedestal top is swing type mechanism, and swing type mechanism can freely rotate in the horizontal direction, and swing type mechanism relatively pedestal has the motion of vertical direction; On swing type mechanism, arrange hinge, chain connection is to hydraulic ram earrings, and hydraulic ram can freely rotate at perpendicular around hinge; Hydraulic cylinder piston rod top is connected to weight, crane hook by steel rope respectively, and crane hook hanging point is than slightly close hinge one side of weight hanging point; The oil pocket of hydraulic cylinder piston both sides connects together by damping hole, and on associated line, energy storage is set.
A deck crane passive type anti roll device, the specific implementation of its rocking-prevention function is: (1) hoisting crane falls puts suspension hook, and crane hook is fixed together by steel rope and hydraulic cylinder piston rod top; (2) weight that will lift hangs over hydraulic cylinder piston rod top; (3) hoisting crane hoists, the action such as revolution, luffing moves to desired location by weight, when hoisting crane carries out these actions, crane hook hauls hydraulic cylinder piston rod top in space motion by steel rope, and then hauls hydraulic cylinder piston rod and overcome the shock damping action of damping hole and stretch; (4) at hoisting crane, hoist, during these actions of revolution, luffing, hydraulic ram can freely rotate at perpendicular with respect to swing type mechanism by hinge, swing type mechanism can freely rotate at horizontal surface with respect to pedestal; (5) under the power that the pulls effect applying at marine crane hook, flexible, the hydraulic ram of deck crane passive type anti roll device by hydraulic cylinder piston rod rotates relative to pedestal relative to the rotating of swing type mechanism, swing type mechanism, can follow crane hook in space motion, the shock damping action of damping hole can alleviate waving of crane hook, thereby realizes passive anti-effect of shaking.
The present invention compares with background technology, has useful effect to be:
(1) under the power that the pulls effect applying at marine crane hook, flexible, the hydraulic ram of deck crane passive type anti roll device by hydraulic cylinder piston rod rotates relative to pedestal relative to the rotating of swing type mechanism, swing type mechanism, can follow crane hook in space motion, the shock damping action of damping hole can alleviate waving of crane hook, thereby realizes passive anti-effect of shaking;
(2) with respect to Maryland rigging mechanism, comprehensive compensating device, deck crane passive type anti roll device has advantages of structure structure, without controlling, cost is low.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of deck crane passive type anti roll device, is characterized in that: this device comprises pedestal 1, swing type mechanism 2, hinge 3, hydraulic ram 4, damping hole 5, energy storage 6.Pedestal 1 is fixed on deck correct position according to deck crane deployment scenarios aboard ship, and pedestal 1 top is swing type mechanism 2, and swing type mechanism 2 can freely rotate in the horizontal direction, and swing type mechanism 2 relatively pedestal 1 has the motion of vertical direction; On swing type mechanism 2, arrange hinge 3, hinge 3 is connected to hydraulic ram 4 earrings, and hydraulic ram 4 can freely rotate at perpendicular around hinge 3; Hydraulic ram 4 piston rod tops are connected to weight 7, crane hook 8 by steel rope respectively, and crane hook 8 hanging points are than slightly close hinge 3 one sides of weight 7 hanging points; The oil pocket of hydraulic ram 4 piston both sides connects together by damping hole 5, and energy storage 6 is set on associated line.
A deck crane passive type anti roll device, the specific implementation of its rocking-prevention function is: (1) hoisting crane falls puts suspension hook, and crane hook 8 is fixed together by steel rope and hydraulic ram 4 piston rod tops; (2) weight 7 that will lift hangs over hydraulic ram 4 piston rod tops; (3) hoisting crane hoists, the action such as revolution, luffing moves to desired location by weight, when hoisting crane carries out these actions, crane hook 8 hauls hydraulic ram 4 piston rod tops in space motion by steel rope, and then hauls hydraulic ram 4 piston rods and overcome the shock damping action of damping hole 5 and stretch; (4) at hoisting crane, hoist, during these actions of revolution, luffing, hydraulic ram 4 can freely rotate at perpendicular with respect to swing type mechanism 2 by hinge 3, swing type mechanism 2 can freely rotate at horizontal surface with respect to pedestal 1; (5) under the power that the pulls effect applying at marine crane hook, flexible, the hydraulic ram 4 of deck crane passive type anti roll device by hydraulic ram 4 piston rods rotates relative to pedestal 1 relative to the rotating of swing type mechanism 2, swing type mechanism 2, can follow crane hook in space motion, the shock damping action of damping hole 5 can alleviate waving of crane hook 8, thereby realizes passive anti-effect of shaking.
