Technical field
The present invention relates to damping devices, more particularly to the damper using complex spring.
Background technology
Complex spring full name is rubber-metal spiral complex spring, is one layer of rubber material of package around metal coil spring
Expect a kind of spring made of composite sulfuration.Complex spring has the non-thread characteristic of rubber spring, and big with metal coil spring
The characteristic of deformation and large carrying capacity, stability and bearing capacity are better than rubber spring.Since complex spring has similar rubber
The characteristic working curve of glue air spring, but simple in structure compared with rubber air spring, gas-tight risk, therefore be also used for
Substitute rubber air spring be widely used in mine, the energy-eliminating shock-absorbing and building shock insulation of the large-scale vibratings equipment such as metallurgy, coal.
Single metal coil spring can only be independently operated on (i.e. so-called tension spring or pressure under stretching or compression one of which state
Spring), and rubber spring often can only operate in compressive state, tensile capacity is weak, therefore compound bullet made of the two composite sulfuration
Spring is typically compressed spring, can only unidirectional vibration damping.If being intended to complex spring being used for two-way vibration damping occasion, need to use at least two
Complex spring forms damper, cuts down direction vibration respectively using the elasticity of compression deformation of two complex springs.
Authorization Notice No. is that the utility application of 204081122 U of CN discloses a kind of wind resistance damping for building
Two elastomers (i.e. two helical springs) in guide sleeve are respectively and fixedly connected on center shaft by spring-damper, the damper
On centre limitation component, when damper is tension or in compression, one of elastomer tension, another elastomer is pressurized, to real
Existing wind resistance damping.But the utility model patent is clearly present following disadvantages：1, two helical springs, entire damper are needed
Length it is longer, be not suitable for installing in the smaller space of distance；2, it is difficult and even impossible two springs of guarantee in technique
Rigidity (including tensible rigidity and compression stiffness) is equal, therefore wind direction difference damping effect is difference；3, damper can not be changed
Initial stiffness, reach default wind resistance rank, reduce the purpose of damping cost；4, a helical spring is being stretched and is being compressed simultaneously
It works under two states, the metal material and production technology of existing spring are difficult to meet the requirements, can only be by reducing helical spring
Regime of elastic deformation come realize stretching with compression two kinds of working conditions, this will obviously result in waste of resources.To by compound bullet
Spring obviously also needs to form wind resistance damper using two complex springs as above-mentioned utility model patent for wind-resistant vibration, and
The damper so formed obviously also have above-mentioned patent it is the same the shortcomings that.
In addition, people for the design of the anti-seismic structure of anti-seismic structure especially high-rise pursue a kind of " anti-" and
The anti-seismic performance for the synthesis that " consumption " is combined, i.e., anti-seismic structure can be that building main body carries under the action of weak wind shake and small earthquake
The effect of external load is resisted for additional additional stiffness, the integrality of retainer body structure avoids in main structure body appearance
Portion is damaged；Anti-seismic structure then starts yield deformation under the action of high wind shakes with violent earthquake, passes through the damper in anti-seismic structure
Damping action come the external energy that dissipates, make main structure body shake and be unlikely to be seriously damaged in violent earthquake even to fall in high wind
It collapses.This just requires that rigidity can be kept under the action of external weak load applied to anti-seismic structure, does not deform；In external intense loading
Energy consumption can be then deformed under the action of lotus.However existing isolated component, either metal spring damper or rubber air bullet
Spring can not perfectly meet above-mentioned antidetonation demand.
The application for a patent for invention of Publication No. CN101457553A discloses one kind, and " spring stiffness adjustable tuning quality subtracts
Shake device ", which is a kind of composite buffer, and the thickness by changing mass block changes its characteristic frequency, viscous by changing
The flow of the working media of stagnant damper changes its damping ratio, and effective active length by changing spring changes its rigidity,
There are three types of the means of the middle effective active length for changing spring, first, spring to be located to one section cured in cylinder using curing materials
Solidification, second is that constraint block is filled in the center of helical spring, and the two is interference fitted, and makes contacted with constraint block one section of spring
Failure between helical raised is stuck in spring wire, makes to block between spring wire third, helical raised is arranged on constraint block surface
There is one section of spring failure of helical raised.The means of effective active length of above-mentioned three kinds of changes spring are simply not proposed to multiple
Close spring；In addition effective active length of the resistance damper of this form not only spring is obviously shortened, but also can only compress energy consumption
Vibration damping cannot stretch passive energy dissipation.
Invention content
Technical problem to be solved by the invention is to provide a kind of complex spring damper that early stage rigidity is predeterminable, the resistances

It can vibration damping.
The present invention solve above-mentioned technical problem technical solution be：
A kind of complex spring damper that early stage rigidity is predeterminable, which includes guide sleeve, the guiding
One of set is equipped with first end cover, and other end is equipped with second end cover；Spring, a drive member are coaxially provided in the guide sleeve
By being put on the outside of first end cover in the guide sleeve, which includes dynamic pressure plate and drive rod, wherein described is dynamic
Pressing plate is located at the head of the spring, and the drive rod is located on dynamic pressure plate and extends guide sleeve along guide sleeve axis；It is special
Sign is,
The spring is complex spring (full name is rubber-metal spiral complex spring), and the outer diameter of the complex spring is less than
The internal diameter of guide sleeve forms therebetween an annular space；
Be additionally provided with backpressure device in the guide sleeve, the backpressure device include quantity be at least respectively two groups of three it is pre-
Compressed steel rope and two pieces of floating platens, wherein
One piece of the floating platen is located between the dynamic pressure plate and complex spring, and another piece is located at second end cover and answers
Between conjunction spring；
Two groups of precompressed cable wires are symmetrically distributed in the annular space rotating around the axis of guide sleeve with linear state
It is interior, and one of one group of precompressed cable wire is separately fixed on the floating platen adjacent with second end cover, other end passes through and dynamic pressure
The adjacent floating platen of plate is separately fixed on dynamic pressure plate, one of another group of precompressed cable wire be separately fixed at it is adjacent with dynamic pressure plate
