Abstract
The invention relates to a damping cylinder for a launching and recovering device of a high-speed work boat. The damping cylinder is characterized by comprising a cylinder barrel, wherein the front end and the rear end of the cylinder barrel are respectively provided with a sealing cap and a barrel bottom, a piston rod is arranged in the cylinder barrel, a disc spring is arranged on the piston rod, and a piston is arranged at the inner end of the piston rod. The centre of the sealing cap is provided with a rod hole, and the outer end of the piston rod penetrates through the rod hole and then stretches out of the sealing cap. The piston matches with the cylinder barrel in a movable sealing mode. The sealing cap and the front end of the cylinder barrel, and the piston rod and the rod hole are both in sealing mode match. The damping cylinder for the launching and recovering device of the high-speed work boat has good damping effect. The service life of a winch can be prolonged by using the damping cylinder for the launching and recovering device of the high-speed work boat. The invention is suitable for launching and recovering devices of high-speed work boats of various kinds of large ships and warships.
Description
Technical field
The present invention relates to a kind of damping device.Specifically, be in when rescue, be used for the damper cylinder of folding and unfolding high speed operation ship, be applicable on the various large ships.
Background technique
All know in the shipbuilding industry, when the naval vessel runs into emergency or saves oneself situation in the navigation process,, often need the high speed operation ship is discharged on the water surface from the naval vessel for satisfying relief and lifesaving needs.After finishing rescue mission, need again the high speed operation ship is recovered on the naval vessel.Therefore, high speed operation ship unwinding and winding mechanism all is equipped with on the naval vessel.Unwinding and winding mechanism wherein contains winch and arm, and winch top is provided with fixing frame, vibration damper is arranged below the fixing frame, and the vibration damper upper end links to each other with fixing frame.Vibration damper lower end and arm front end all are equipped with pulley, between winch and arm wire rope are arranged, and wire rope one end connects and on the capstan winch of winch, and the other end links to each other with a suspension hook after walking around the pulley of the pulley of vibration damper lower end and arm front end successively.When need folding and unfolding high speed operation ship, make suspension hook catch on quick dink earlier, restart winch, wire rope is twined or release, thereby realize the folding and unfolding of high speed operation ship.When the high speed operation ship was subjected to wave stroke, pull of steel wire can produce acute variation in the folding and unfolding process, and the effect by vibration damper can prevent that the sudden change of lineoutofservice signal pull from bringing impact to winch, avoids the damage of winch.
At present, the vibration damper that uses in the high speed operation ship unwinding and winding mechanism mostly is a helical spring shock absorber.Because helical spring rigidity and decrement are limited, prevent the lineoutofservice signal pull sudden change to the influence that winch brings, just require helical spring to want enough big.Helical spring one is big, can increase the weight and the installing space of vibration damper again.The factor of comprehensive helical spring shock absorber each side, used helical spring can not be enough big.Therefore, adopt helical spring shock absorber, not only damping effect is poor, and can shorten the working life of winch.
Summary of the invention
The problem to be solved in the present invention provides a kind of high speed operation ship unwinding and winding mechanism damper cylinder.This high speed operation ship unwinding and winding mechanism damper cylinder, good damping effect.Adopt this high speed operation ship unwinding and winding mechanism damper cylinder, can prolong the working life of winch.
For addressing the above problem, take following technological scheme:
High speed operation ship unwinding and winding mechanism of the present invention is to comprise cylinder barrel with the damper cylinder characteristics, and the front-end and back-end of cylinder barrel have the capping and the tube end respectively, and piston rod is arranged in the cylinder barrel, and the dish spring is arranged on the piston rod, and there is piston the piston rod inner end.There is the bar hole at the capping center, and stretch out outside capping after passing the bar hole piston rod outer end.Be moving type between piston and cylinder barrel and be sealed and matched, between capping and cylinder barrel front end, all be the sealing shape between piston rod and described bar hole and cooperate.
Wherein, described dish spring be in twos concave surface to pile after stack together again.
The further improvement of the present invention scheme is, on the cylindrical of piston circumferential recess arranged, and motive sealing is arranged in the circumferential recess.
Further improvement project of the present invention is, the tubular internal projection is arranged on the inner side surface of described capping, and this tubular internal projection stretches in the cylinder barrel.On the interior circle of described tubular internal projection He on the cylindrical circumferential recess is arranged all, seal ring is arranged in the circumferential recess.
Take such scheme, have the following advantages:
By such scheme as can be seen, comprise that cylinder barrel, the front-end and back-end of cylinder barrel have the capping and the tube end respectively because the present invention adopts, piston rod is arranged in the cylinder barrel, the dish spring is arranged on the piston rod, there is piston the piston rod inner end.There is the bar hole at the capping center, and stretch out outside capping after passing the bar hole piston rod outer end.Be moving type between piston and cylinder barrel and be sealed and matched, between capping and cylinder barrel front end, all be the sealing shape between piston rod and described bar hole and cooperate.When piston rod is subjected to tensile impact, the Piston Compression spring, piston rod is protruding, absorbs impact energy, plays damping effect.Because concave surface stacks together after piling up again to adopt the dish spring to be in twos, can absorb bigger impact energy, by regulating the pretightening force of dish spring, can improve damping effect, prevent the adverse effect that the lineoutofservice signal pull sudden change brings winch, thereby prolong the working life of winch.
