Abstract
The invention relates to a damper displacement speed amplifying device with a variable amplification factor. The damper displacement speed amplifying device comprises levers with variable amplification factors, fulcrum shafts, connecting plates, damper outer plates and a middle plate. The connecting plates are fixedly connected with an upper floor beam. The damper outer plates are fixedly connected with a lower floor beam. The upper ends of the levers are hinged to the connecting plates. The lower ends of the levers are hinged to the middle plate. The middle upper portion of each lever is provided with a groove. The fulcrum shafts penetrate through the damper outer plates and the grooves in the levers and are fixed to the damper outer plates, so that the fulcrum shafts cannot be moved relatively. When the upper floor beam moves, the levers can vertically move around the fulcrum shafts, and the purpose of changing the amplification factor is achieved. The story drift of a structure is amplified by the levers with the variable amplification factors and then acts on the middle plate of a damper, so that the relative displacement and the relative speed of the damper are increased, the energy-dissipating capacity of the damper is improved, and it is guaranteed that under the condition that the damper provides sufficient damping force, the relative displacement of the damper is within an allowable displacement range.
Description
Technical field
The present invention relates to the damper displacement speed amplifying device that a kind of enlargement ratio is variable.
Background technology
The existing damper energy consumption effect that only competence exertion is good under larger structure relative storey displacement and speed.As the relative storey displacement of fruit structure and speed relatively little, damper just fully can not provide damping force, and damping/effect of shaking is undesirable.In order to increase the damping force of damper in engineering practice, often adopting the mode increasing damper size to realize, so not only increasing construction cost, and the using function of impact building.Although existing patent can solve by additional displacement amplifying device the problem that damper fully can not provide damping force in the less situation of relative storey displacement, but also can exist relative storey displacement larger time, above-mentioned amplifying device still can amplify the relative displacement of damper, it is made to exceed tolerance limit displacement, damper damage inactivation.
Summary of the invention
For the defect that prior art exists, the object of this invention is to provide the damper displacement speed amplifying device that a kind of enlargement ratio is variable, make damper in the less situation of relative storey displacement, amplify its relative displacement and relative velocity, thus produce larger damping force, improve energy consumption effect.Along with structure relative storey displacement increases, enlargement ratio reduces even not amplify gradually, can ensure that the displacement of damper is no more than tolerance limit displacement like this, fully can provide damping force again, and energy consumption effect is desirable.
For achieving the above object, the present invention adopts following technical scheme:
The damper displacement speed amplifying device that enlargement ratio is variable, comprises the variable lever of enlargement ratio, fulcrum shaft, junction plate and damper outside plate, intermediate plate; Described junction plate is fixedly connected with upper floor beam, and described outside plate is fixedly connected with lower floor floor beam; Described lever upper end and junction plate hinged, lower end and intermediate plate hinged, have a groove in the middle and upper part of described lever, described fulcrum shaft through the groove on damper outside plate and lever, and is fixed on damper outside plate, relative movement can not occur; When upper floor Liangping is moved, described lever can move up and down around fulcrum shaft, realize the object changing enlargement ratio, the relative storey displacement of structure is by acting on the intermediate plate of damper after lever amplification, the relative displacement of damper and relative velocity are increased, promote its energy dissipation capacity, and guarantee damper fully provide damping force while its relative displacement be no more than tolerance limit displacement.
When structure relative storey displacement is less, damper displacement speed enlargement ratio is comparatively large, thus the relative displacement of damper and relative velocity comparatively large, energy consumption effect is remarkable.Along with structure relative storey displacement increases gradually, lever moves up around fulcrum shaft, and enlargement ratio constantly reduces even not amplify, thus damper can guarantee that its relative displacement is no more than tolerance limit displacement while fully providing damping force.After the velocity of displacement amplifying device that additional enlargement ratio is variable, in damper reciprocatory movement, energy efficiency is high, and can not destroy.
The slot length that the lever that described enlargement ratio is variable is arranged sets according to the maximum relative storey displacement of structure, the displacement of damper tolerance limit and lever amplification multiplying power.
The maximum damping force that the number of the damper displacement speed amplifying device that additional described enlargement ratio is variable can provide according to damper on damper is determined.
Compared with prior art, the present invention has following outstanding feature and significant technological progress:
The present invention, by adding the variable velocity of displacement amplifying device of enlargement ratio on damper, makes damper in the less situation of relative storey displacement, amplifies its relative displacement and relative velocity, thus produces larger damping force, improves energy consumption effect.Along with structure relative storey displacement increases, enlargement ratio reduces even not amplify gradually, and can guarantee that while damper fully provides damping force the displacement of damper is no more than tolerance limit displacement, damper can not destroy.

Detailed description of the invention
The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment.
Shown in composition graphs 1-Fig. 9, the damper displacement speed amplifying device that a kind of enlargement ratio is variable, comprises the variable lever of enlargement ratio 1, fulcrum shaft 2, junction plate 3 and damper outside plate 4, intermediate plate 5; Described junction plate 3 is fixedly connected with upper floor beam, and described outside plate 4 is fixedly connected with lower floor floor beam; Described lever 1 upper end and junction plate 3 hinged, lower end and intermediate plate 5 hinged, have a groove in the middle and upper part of described lever 1, described fulcrum shaft 2 through the groove on damper outside plate 4 and lever 1, and is fixed on damper outside plate 4, relative movement can not occur; When upper floor Liangping is moved, described lever 1 can move up and down around fulcrum shaft 2, realize the object changing enlargement ratio, the relative storey displacement of structure is by acting on the intermediate plate 5 of damper after lever 1 amplification, the relative displacement of damper and relative velocity are increased, promote its energy dissipation capacity, and guarantee damper fully provide damping force while its relative displacement be no more than tolerance limit displacement.
When structure relative storey displacement is less, damper displacement speed enlargement ratio is comparatively large, thus the relative displacement of damper and relative velocity comparatively large, energy consumption effect is remarkable.Along with structure relative storey displacement increases gradually, lever 1 moves up around fulcrum shaft 2, and enlargement ratio constantly reduces even not amplify, thus damper can guarantee that its relative displacement is no more than tolerance limit displacement while fully providing damping force.After the velocity of displacement amplifying device that additional enlargement ratio is variable, in damper reciprocatory movement, energy efficiency is high, and can not destroy.
The slot length that the lever 1 that described enlargement ratio is variable is arranged sets according to the maximum relative storey displacement of structure, the displacement of damper tolerance limit and lever amplification multiplying power.
