Background technique
It is generally acknowledged the kind that to select vibration isolator according to the energizing frequency under the working environment, energizing frequency is when low frequency is more, select preferably steel-wire isolator of low frequency vibration isolation, energizing frequency is selected preferably liquid damping vibration isolator of high-frequency vibration isolation when high frequency is more.But the actual working environment of boats and ships is complicated and changeable, operating mode in the startup of ship power element, operation and the stopped process is also just complicated and changeable, so the vibration isolator of choosing should both adapt to low-frequency vibration and adapt to again dither, but existing vibration isolator seldom can be simultaneously carries out vibration isolation to low frequency operating mode and high frequency operating mode.
Most vibration isolator peculiar to vessel is as main take rubber vibration isolator and steel-wire isolator.Rubber vibration isolator low price, low frequency vibration isolation are functional, but there are the rubber shortcomings such as easily aging, high temperature resistance and impact resistance be weak in rubber vibration isolator.Steel-wire isolator has good vibration and impact property, has multidirectional large displacement resiliently deformable function, maximum dynamic deformation can reach about 100mm, although this dynamic deformation function is conducive to resist the large impact distortion and reduces shock response, but because the monotony of its structure, it all can produce displacement in three directions, can not the vibration isolation requirement of to satisfy effectively ship equipment under complex working condition.This just needs vibration isolator can adapt to vibration isolation requirement under changeable, the complex working condition.
Summary of the invention
The object of the invention is to provide a kind of metal spring wire rope liquid damping vibration isolator, and vibration and impact that it can effectively reduce ship equipment are quick on the draw, and can make the ship equipment of vibration keep the works fine performance.
The present invention adopts following technological scheme:
A kind of metal spring wire rope liquid damping vibration isolator comprises clamping plate, liquid condenser, metal spring, steel-wire isolator, yoke plate; Described clamping plate comprise punch holder, die holder, and the up and down two ends of described liquid condenser are fixed with punch holder, die holder bolt respectively; Described metal spring is enclosed within on the liquid condenser; Described steel-wire isolator and yoke plate bolt are fixed; Described yoke plate has four, is symmetrically arranged in the both sides of liquid condenser and is welded on the clamping plate.
Further, top, the die holder of described punch holder below be separately installed with the rubber plate that shore hardness is.
Further, described liquid condenser is the piston type damper.
Further, described steel-wire isolator has two, is symmetrically arranged in the both sides of liquid condenser.
Further, described steel-wire isolator is made of wire rope spring and wire rope spring clamping plate, be drilled with bolt mounting holes on the wire rope spring clamping plate, the bolt mounting holes of even number is used for connecting up and down wire rope spring clamping plate from left to right, and the bolt mounting holes of odd number is used for steel-wire isolator is fixed on yoke plate.
Further, be drilled with mounting hole above the described yoke plate, corresponding with the bolt mounting holes on the described wire rope spring clamping plate, be used for installing steel-wire isolator.
Further, described wire rope spring clamping plate are divided into wire rope spring punch holder and wire rope spring die holder; Have the identical semi-circular recesses of some sizes on described wire rope spring punch holder and the wire rope spring die holder corresponding position, form a circular hole; The radius of described circular hole is identical with the wire rope radius of wire rope spring; Distance between described per two circular holes is identical with the spacing of the spring thread of per two wire rope springs.
The present invention's beneficial effect compared with prior art is: safe and reliable, not only can effectively limit the displacement of wire rope on the three degree of freedom direction, effectively reduce the vibration of ship equipment, ship equipment Operation safety and reliability have been improved, and impact is quick on the draw, can make system keep the works fine performance, prolong the working life of vibration isolator.
