Description
Technical field
The utility model is related to a kind of mutative damp viscous damper, belongs to field of civil engineering.
Background technology
Viscous damper is a kind of important form in energy-dissipating and shock-absorbing technology, and the device is general by cylinder body, piston, damping
The part such as hole, viscous fluid damping material and guide rod constitutes, and piston can move back and forth in cylinder barrel, have on piston appropriate aperture into
It is damping hole, viscous fluid damping material is filled in cylinder barrel.When there is relative motion between piston and cylinder barrel, fluid damping material
Material from damping hole by when produce damping force, so as to reach the purpose of power consumption.Effects of Viscous Fluid Damper vibrates to structure
The mechanism of control is that the portion of energy of structural vibration is dissipated by the viscous power consumption of viscous fluid damping material in damper,
Reach the purpose for reducing structural vibration earthquake or Wind Vibration Response.
Existing damping viscous damper can not provide the damping force of stabilization under big shake effect for structure, reduce variable resistance
The mutative damp meaning of Buddhist nun's viscous damper.So proposing that it is have very much that can stablize the mutative damp viscous damper for keeping big damping state
It is necessary.
Utility model content
For the defect that prior art is present, the purpose of this utility model is to provide a kind of mutative damp viscous damper,
So that viscous damper provides larger damping force in the case of big shake.
In order to achieve the above object, to solve the scheme that its technical problem used as follows for the utility model：
A kind of mutative damp viscous damper, including master cylinder, outer sleeve, variable damper control valve, guide rod, additional damping passage,
Piston, secondary cylinder, sealing ring；The master cylinder is placed in outer sleeve, and the secondary cylinder is arranged on the outside of outer sleeve, the mutative damp control
Valve processed is respectively arranged on master cylinder, and the additional damping passage is connected with master cylinder；The guide rod is through in master cylinder, outer sleeve
The heart, piston is provided between the both sides of guide rod and master cylinder, and the close of oil-leakage-prevention is provided between the two ends tapping and guide rod of master cylinder
Seal ensures that viscous liquid does not leak outside, the opening and closing control additional damping channels operation of variable damper control valve.
The variable damper control valve is made up of damping control baffle plate, valve controling rod and block rubber；The damping control gear
One end of plate is hinged on the inwall of master cylinder, other end freedom, and damping control baffle plate is provided with chute, the valve controling rod
One end is arranged in the chute of damping control baffle plate, and the other end is arranged on the outer wall of master cylinder, and the upper end of valve controling rod is fixed
There are two block rubbers as spacing；The outlet of the additional damping passage is arranged at the top of damping control baffle plate.
Compared with prior art, the utility model has advantages below：
1st, viscous damper provides the big control targe for damping under the utility model can meet big displacement state.
2nd, after variable damper control valve closure, additional damping passage closed permanent, mutative damp viscous damper keeps big
Damping state, and relative displacement change is influenceed not by after.
3rd, consumed energy under big damping state and increased, the seismic response of structure can be effectively reduced.
Brief description of the drawings
Fig. 1 is mutative damp viscous damper structural representation.
Fig. 2 is variable damper control valve detail drawing.
Fig. 3 is valve controling rod side view.
Fig. 4 is damping control baffle plate schematic diagram.
Specific embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of mutative damp viscous damper, including master cylinder 1, outer sleeve 2, variable damper control valve 3,
Guide rod 4, additional damping passage 5, piston 6, secondary cylinder 7, sealing ring 8；The master cylinder 1 is placed in outer sleeve 2, and the secondary cylinder 7 is installed
In the outside of outer sleeve 2, the variable damper control valve 3 is respectively arranged on master cylinder 1, and the additional damping passage 5 connects with master cylinder 1
It is logical；The guide rod 4 is provided with piston 6, in master through master cylinder 1, the center of outer sleeve 2 between the both sides of guide rod 4 and master cylinder 1
The sealing ring 8 of oil-leakage-prevention is provided between the two ends tapping and guide rod 4 of cylinder 1.
The variable damper control valve 3 is made up of damping control baffle plate 9, valve controling rod 10 and block rubber 11；The damping
One end of controlling baffle plate 9 is hinged on the inwall of master cylinder 1, other end freedom, and damping control baffle plate 9 is provided with chute, the valve
One end of gate control bar 10 is arranged in the chute of damping control baffle plate 9, and the other end is arranged on the outer wall of master cylinder 1, valve control
The upper end of bar processed 10 is fixed with two block rubbers 11 as spacing；The outlet of the additional damping passage 5 is arranged at damping control
The top of baffle plate 9.
During thin tail sheep state, variable damper control valve 3 is in open mode, and now viscous fluid is simultaneously by piston 6
Damping hole and additional damping passage 5, produced damping force are smaller.As displacement increases, piston 6 promotes variable damper control valve 3
Damping control baffle plate 9, valve controling rod 10 is pushed up, when the protruding parts of control-rod 10 are by the spacing work of block rubber 11
With valve controling rod 10 will not be moved downward again, and damping control baffle plate 9 forever closes additional damping passage 5, viscous damper
Keep big damping state.
