Each side of the piston in the main cylinder inner is provided with an unidiameter piston rod; wherein, the piston rod of one side crosses a sealing sleeve and the centre hole of the end of the casing cap to connect the end cover of the protect cylinder; the piston rod at the other side crosses the sealing sleeve and the center hole of the end of the casing cap to reach the chamber of the auxiliary cylinder. A damping interstice is formed between the damping orifice arranged on the piston and the piston diameter which is smaller than the inner diameter of the master cylinder. The viscosity damping buffer has simple structure, cheap manufacturing cost and high price ratio for the convenience of production and popular application. The utility model can not only be used for newly-made structure, but also can be used for existed structural reinforcing reconstruction.
Description
Technical field
The utility model relates to a kind of viscous damping buffer, is applicable to engineering vibration damping and structure control field.
Background technique
Along with the progress of expanding economy and human society, earthquake is also increasing to the harm that the mankind cause.Socioeconomic Security, applicability and the travelling comfort that develops rapidly modern building fabric had higher requirement simultaneously.Traditional Aseismic Structure System is to come " resisting " geological process by the performance that strengthens structure itself, is promptly stored and earthquake energy by structure itself, to satisfy the requirements for fortification against earthquake of structure.Because people still can not estimate intensity, the frequency spectrum of the earthquake motion that structure may meet with in future exactly and characteristic such as when holding, and do not possess the ability of self-control and oneself's control according to its anti-seismic performance of structure of traditional anti-shock methods design, therefore under this probabilistic geological process, structure can not satisfy the requirement of Security.Therefore, structure energy-eliminating shock-absorbing method and technical system are arisen at the historic moment.This system is that design power consumption rod member is set at some position of structure, when structure shake (shaking) is moving, these member rates are introduced into plastic state, consume shake (shaking) energy to guarantee the safety of building under big shake or high wind, and wherein key technology is power consumption member---the damper of high performance-price ratio.The present viscous damper that uses of engineering circle exists defectives such as power consumption weak effect, viscous medium are revealed easily, cost height, the dustproof anticorrosive measure is improper, volume is big.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art, and the viscous damping buffer of a kind of highly energy-consuming, good airproof performance, simple in structure, high performance-price ratio is provided, and is used for the antidetonation vibration damping of building structure.
A kind of viscous damping buffer of the present utility model is seen accompanying drawing 1, the viscous medium that it includes master cylinder, is arranged at the piston that can move vertically in the master cylinder, the piston rod that is connected with piston and master cylinder inner chamber are filled; It is characterized in that: the master cylinder 1 outer protection cylinder 2 that is arranged with, a uncovered end of master cylinder 1 is connected with secondary cylinder 6; The both sides of the piston 3 that is provided with in the Master cylinder body 1 respectively are connected with piston rod 4; wherein an end of Yi Bian piston rod passes stuffing box gland 5, holds the center hole of plug 8 to link to each other with the end cap 15 of protection cylinder 2, and an end of the piston rod of another side passes the center hole of stuffing box gland 5 and end plug 8 to secondary cylinder chamber 14.And the end of secondary cylinder and protection cylinder all is connected with earrings 10.
Have damping hole 11 on the piston 3 described in the utility model, the diameter of piston 3 forms damping gap 7 less than the internal diameter of master cylinder 1, between the two; And piston 3 both sides are provided with isodiametric piston rod 4.
Two ends are provided with stuffing box gland 5 in master cylinder described in the utility model 1 chamber, respectively have 5 cover seal rings 13 inside and outside the stuffing box gland, and stuffing box gland is fixing by end plug 8, and end plug 8 and master cylinder are with being threaded.
The working principle of viscous damping buffer of the present utility model is to try hard to recommend outside to move down, promoting piston 3 moves in master cylinder, viscous medium in piston pushing master cylinder 1 cavity, make the viscous medium by damping hole 11 and damping gap 7, produce the damping of contracting of frictional damping and hole, consume the energy of vibration, make kinetic energy be converted into heat energy, heat energy is dissipated in the air.Because the viscous medium is flowed in gap and aperture by external force, can not produce bounce-back when being subjected to impacting, thereby do not make this structure very steadily, do not beat.
The viscous damping that viscous damping buffer of the present utility model produced, earthquake, wind to structure shakes, mechanical vibration are very responsive, the power consumption curve is very full, test shows, curve can be ellipse, also can be " returning " shape, and have under micro-displacement highly energy-consuming and characteristics such as speed hypersensitivities.

Among the figure: the inner chamber 14 of master cylinder 1, protection cylinder 2, piston 3, piston rod 4, stuffing box gland 5, secondary cylinder 6, damping gap 7, end plug 8, viscous medium 9, the screw thread 12 that connects setting in earrings 10, damping hole 11, the mechanical part connection, seal ring 13, secondary cylinder 6, the end cap 15 of protection cylinder 2.
Embodiment
Viscous damping buffer embodiment of the present utility model 1 is done following specifying in conjunction with the accompanying drawings.Adopt universal accessories according to Fig. 1, the elongated axial damping hole of processing on piston is placed on the design attitude of master cylinder with piston, and stuffing box gland and end plug are installed in design attitude, utilizes pot-type equipment that the damping viscous material is full of master cylinder 1; Secondary cylinder and protection cylinder are installed again, are carried out the connection of earrings, promptly can realize the utility model.
In addition, for realizing desired linear damping of engineering structure and nonlinear dampling, the piston of viscous damping buffer is provided with damping hole and damping gap; For guaranteeing the multi-sealed of viscous medium, viscous damping buffer is provided with ten cover seal arrangements; Avoid foreign impacts and corrosion, viscous damping buffer peripheral hardware protection cylinder for preventing master cylinder; And piston rod links to each other with the protection cylinder of peripheral hardware, has avoided the pressurized unstability at the volley.Adopt the viscous medium of stable performance in the master cylinder cavity, evidence, this product can be suitable in-40 ℃~110 ℃ ambient temperature.
Viscous damping buffer of the present utility model also can be by changing the viscous medium kind and the parameter of physical dimension, manufacture and design performance difference, product that Applicable scope is different.
Viscous damping buffer Applicable scope of the present utility model is extensive, can be widely used in the earthquake resistant engineering, wind resistance of building structure, bridge structure, lifeline engineering, tall and slender structure etc.And both can be used for newly-built structure, also can be used for the strengthening reconstruction of existed building.
