Description
Technical field
The present invention relates to vibration damping antidetonation field, be specifically related to a kind of viscous damper that has axially stop block.
Background technique
The viscous damper of development is the speed interdependence both at home and abroad at present, mainly the structural dynamic response that causes is carried in greater impacts such as earthquake outward and play the damping energy dissipation effect, therefore low speed static load (causing as temperature variation) damping force is had only below 10% of former damping force, and the malformation that the distortion of basic load is caused does not have damping function.In case produce unexpected basic load and excess displacement, speed interdependence viscous damper will not satisfy function of use, and structure will be destroyed.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of antidetonation dynamic energy consumption technical requirements of satisfying for the defective that overcomes above-mentioned prior art existence, satisfies the viscous damper that has axially stop block of the technical requirements of basic load and the displacement of restriction excess simultaneously.
Purpose of the present invention can be achieved through the following technical solutions: the viscous damper that has axially stop block, comprise left ball pivot seat, piston rod, piston, resistance cylinders, balancing pole, right ball pivot seat, resisting medium, described left ball pivot seat is connected with piston rod, piston rod is arranged at the piston left side, balancing pole is arranged at the piston right side, described piston radial is arranged at resistance cylinders inside, described resisting medium is arranged in the resistance cylinders, it is characterized in that, also comprise dish-shaped-spring stack, spacing cylinder body, pressure ring A, pressure ring B, described spacing cylinder body is arranged between resistance cylinders and the right ball pivot seat, spacing cylinder body two ends are provided with internal thread, its left end is connected its right-hand member and pressure ring B by pressure ring A with resistance cylinders, right ball pivot seat connects, and the length lengthening of described balancing pole extends in the spacing cylinder body, and one screwed small column being set at the balancing pole right-hand member, described dish-shaped-spring stack is installed on the small column.
Described small column end is provided with outside thread, dish-shaped-spring stack is installed on the small column, and fixes with round nut.
Spacing rigidity of structure and spacing displacement are satisfied in the making of described dish-shaped-spring stack.
Described pressure ring A is provided with outside thread, respectively with resistance cylinders and spacing cylinder body by being threaded.
Described pressure ring B is provided with outside thread, respectively with spacing cylinder body and right ball pivot seat by being threaded.
Described spacing cylinder body adopts seamless steel pipe to make, and two ends are machining internal thread all.
Compared with prior art, the present invention prolongs the length of balancing pole on the basis of common viscous damper, and dish-shaped-spring stack is installed in the end of balancing pole, between right ball pivot seat and resistance cylinders, increase a spacing cylinder body simultaneously, the left side is connected with resistance cylinders by pressure ring A, and the right is connected with right ball pivot seat with pressure ring B.Under the viscous damper tension state, left ball pivot seat drives piston rod, piston, balancing pole toward left movement, and when the distortion of structure static load surpasses damping stroke S, fit in the A plane of dish-shaped-spring stack and pressure ring A.Dish-shaped-spring stack begins compression, produces spring resistance, plays the position-limiting action that draws direction.Under the viscous damper pressured state, left side ball pivot seat drives piston rod, piston, balancing pole toward right motion, when the distortion of structure static load surpasses damping stroke S, fit in the B plane of dish-shaped-spring stack and pressure ring B, dish-shaped-spring stack begins compression, produce spring resistance, play the position-limiting action that draws direction.This dish-shaped-spring stack resistance and loading velocity are irrelevant, and be only relevant with the structural static deformation position.In order effectively to guarantee the static load Deformation control within scope of design, the rigidity of this belleville spring can be selected for use according to the relation design of load and distortion.Make damper not only satisfy the technical requirements of antidetonation dynamic energy consumption, satisfy the technical requirements of basic load and the displacement of restriction excess simultaneously.
