Specific embodiment
The present invention is described in further detail below with reference to the drawings and specific embodiments.
Intelligent buffer device shown in Figure 1, that a kind of rigidity vibration isolation of the invention is automatically switched with damping buffering, including
The liquid cylinder being made of cylinder body body 20, cylinder end caps A21 and cylinder end caps B22, is installed in inside liquid cylinder from top to bottom
Non-porous piston A61, the flow check piston 4 for being internally provided with throttle orifice 40, non-porous piston B62, the T-shaped shifting being installed on flow check piston 4
Movable plate 3.
Shown in Figure 1, T-shaped movable plate 3 is through non-porous piston A61 and cylinder end caps B22 and extends to the outer of liquid cylinder
Portion；Metal coil spring A7 is installed between non-porous piston A61 and cylinder end caps B22.
It is shown in Figure 1, it is equiped with metal coil spring B8 between non-porous piston B62 and cylinder end caps A21.
Shown in Figure 1, non-porous piston A61, non-porous piston B62 and flow check piston 4 can be freely along cylinder body bodies 20
Inner wall is free to slide；It is internal there is no viscous liquid for first without sap cavity between non-porous piston A61 and cylinder end caps B22.It is non-porous
It is internal there is no viscous liquid for second without sap cavity between piston B62 and cylinder end caps A21；Non-porous piston A61 and flow check piston
Fluid chamber A51 is constituted between 4, fluid chamber B52 is constituted between non-porous piston B62 and flow check piston 4.
Shown in Figure 1, metal coil spring A7 and metal coil spring B8 is metal helical drawing-pressing spring, and in zero
During stress, viscous liquid is full of inside fluid chamber A51 and fluid chamber B52.
The course of work and operation principle：The equipment of this vibration isolation is installed in the upper end of T-shaped movable plate 3.When equipment be subject to it is larger
Outer diameter exciting force when, flow check piston 4 is synchronized with the movement with T-shaped movable plate 3, so that between fluid chamber A51 and fluid chamber B52
Viscous liquid flowed by the throttle orifice 40 on flow check piston 4, the flowing of viscous liquid will be generated to flow check piston 4 and T-shaped
The damping buffering power of movable plate 3, at this time non-porous piston A61 and non-porous piston B62 relatively small displacement will occur, i.e., just at this time
Degree vibration isolating effect can be ignored.
When external exciting force is very big suffered by flow check piston 4, with flow check piston 4 movement will so that fluid chamber A51 or
One of space vanishing of fluid chamber B52, at this time non-porous piston A61 or non-porous pistons B62 by be significantly compression compared with
Metal coil spring, almost non-viscous liquid in throttle orifice 51 at this time, hence into rigidity vibration isolation state.Therefore, the external world is worked as
When exciting force is smaller, the present invention is mainly damping buffering, and when extraneous exciting force is larger, the present invention initially enters damping buffering,
It automatically switches to afterwards in rigidity vibration isolation state.
