The technical scheme that this utility model provides is by arranging described main part and described slave part, described main part and described slave part all include piston rod and sleeve, described piston rod can move along described slip expansion, and the stretching motion of described piston rod is damped power, described amortisseur is had, hence in so that the vibrations produced during the motion of described motion parts are delivered to during described standing part be cut down owing to connecting between described motion parts and described standing part.Simultaneously, further, owing to described main part becomes herringbone structure with described slave part, the auxiliary set cylinder of described slave part is articulated with described master collet outer wall, the power that described slave part is subject to has component along orthogonal both direction, a part of component that a portion component and described main part are subject to cancels each other, thus the motion parts further reducing external equipment passes to the active force of standing part, therefore improve the damping effect of amortisseur, further reduce vibrations during equipment work.
Preferably, it is provided with damping material between described piston rod and sleeve.
Damping material can be gas, liquid or solid, it is possible to is used in mixed way.Such as, when damping material is gas, it is possible to use air damper；When damping material is liquid, it is possible to use hydraulic damper；When damping material is solid, it is possible to use spring-damper.Preferably, described damping material is oil-containing damping material, to reduce frictional resistance.Preferably, oil-containing damping material is siliceous fatty oil cotton material, is placed between piston and loop bar, has viscous damping effect.
Preferably, when described main part 10 is air damper or hydraulic damper or spring-damper, described slave part 20 can also be air damper or hydraulic damper or spring-damper.Below these three damping shock absorber is briefly described one by one.
The resisting medium of air damper is air, is a kind of damping device utilizing air viscosity, can overcome some shortcoming that liquid sticky damps.Owing to the compressibility of air is relatively big, larger displacement therefore can be born.For liquid, the viscosity of air varies with temperature not quite, thus performance is more stable.
The structure of hydra-shock absorber with suction-type pump basic simlarity, difference be the cylinder body upper end of hydraulic damper be to close, and leave aperture on the piston valve being connected with piston rod.When piston moves down in inner cylinder tube relatively, the oil of inner cylinder tube intracavity piston underside is flowed on the upside of piston by the aperture on piston valve.Meanwhile, this part oil flows in the oil pocket between inside and outside cylinder barrel also by the aperture on bottom valve.The most effectively decay impact load.When piston moves up relative to cylinder barrel, on the downside of the aperture flow direction on piston valve of the oil on the upside of inner cylinder tube piston.Now during fluid flows through aperture, preferable damping action can be this creates the terminal by the biggest resistance, serves the purpose of damping.
Damping spring amortisseur is provided with spring between piston rod and sleeve, in order to shock absorbing load, it is achieved damping purpose.
Further, as it is shown on figure 3, the length of described slave part 20 is more preferably less than the length of described main part 10, described master collet afterbody supports the motion parts of described external equipment obliquely.It should be noted that the length of described slave part 20 mentioned here is less than the length of described main part 10, refer to the length when piston rod of described slave part and described main part stretches out simultaneously or retracts simultaneously.When motion parts is in the top of described amortisseur, described main part 10 and described slave part 20 play a supportive role simultaneously.
Preferably, as it is shown on figure 3, the angle of described slave part 20 and described main part 10 is acute angle.
During actual application, as shown in Figure 4, hinged between master collet 12 and auxiliary set cylinder 22.Described amortisseur is carried out force analysis as follows: in figure, F1 represents main part damping force (X, Y-direction component Fx1, Fy1), F2 represents slave part damping force (X, Y-direction component Fx2, Fy2), then make a concerted effort Fv=Fy1+Fy2, horizontal direction of vertical component is made a concerted effort Fh=Fx1-Fx2.Visible, main part 10 and slave part 20 power in the horizontal direction can cancel each other a part, thus reduce vibrations.
