Embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the utility model mainly comprises hydraulic cylinder 8, is provided with piston plate 6 in hydraulic cylinder 8, between piston plate 6 and hydraulic cylinder 8 sidewalls, is provided with certain gap.Hydraulic cylinder 8 upper ends, by the second bolt 12 adpting flange lids 3, are provided with an O RunddichtringO 4, the sealing guaranteed between hydraulic cylinder 8 and blind flange 3 by an O RunddichtringO 4 between hydraulic cylinder 8 and blind flange 3.
Piston plate 6 is threaded connection piston rod 2, and blind flange 3 is stretched out in piston rod 2 upper ends, and piston rod 2 upper ends are threaded connection mounting plate 1.
Piston plate 6 upper ends connect clamping panel 14 by the first bolt 11, clamp an end of elastic packing interlayer 5 between clamping panel 14 and piston plate 6, and the other end of elastic packing interlayer 5 clamps by hydraulic cylinder 8 and blind flange 3.Described elastic packing interlayer 5 adopts rubber material to make, and has certain extensibility, can leak by sealed hydraulic cylinder body 8 interior hydraulic oil.
Be provided with the 2nd O RunddichtringO 10 between described clamping panel 14 and piston rod 2, the sealing guaranteed between clamping panel 14 and piston rod 2 by the 2nd O RunddichtringO 10.
Described piston plate 7 is provided with a plurality of damping holes 13, meeting frictional heat when fluid is flowed through damping hole 13, and the relative movement energy of consumption systems, the peak response characteristic of improvement system, reduce the power augmentation factor.And the movement velocity that can block piston, the response time that has delayed vibration or impacted, thereby the response that reduces vibration or impact.
Connect gas charging valve 9 on hydraulic cylinder 8 outer side walls, gas charging valve 9 is communicated with the air bag 7 in hydraulic cylinder 8, realizes inflation or the venting of air bag 7 by gas charging valve 9.
Working principle of the present utility model is: when work, in hydraulic cylinder 1, fill hydraulic oil.Be filled with initial air by gas charging valve 9 in air bag 7 before using, make it keep certain interior pressure.Under given external load state, air bag 7 is in internal and external pressure balance state (being original state), and at this moment system has the natural frequency (being generally 1.5～2HZ) of setting; Can be by regulating the initial gas pressure in air bag 7, to reach different load bearing requirements.
When the utility model is subject to extraneous vibration or percussion, piston rod 2 and piston plate 6 can pump along hydraulic cylinder 8.Incompressibility due to fluid; the pressure of determining volume fluid in hydraulic cylinder 8 changes and can force interior pressure and the volume of air bag 7 interior gases to change; the input energy that makes vibration or impact is converted into the pressure energy of sealing gas-liquid; thereby reduce vibration or the shock response of hydraulic cylinder 8, effectively protected the supporting basis of hydraulic cylinder 8.In addition, be provided with a plurality of damping holes 13 on piston plate 6, meeting frictional heat when fluid is flowed through aperture, the relative movement energy of consumption systems, the peak response characteristic of improvement system, reduce the power augmentation factor.And the movement velocity that can block piston, the response time that has delayed vibration or impacted, thereby the response that reduces vibration or impact.
