Include abutment, bridge pier and basis；Attached structure then refers to transition slab at bridge head, truncated cone banking, shore protection, training works etc..
Bridge refers to the building built across natural or cultural obstacle for road.Bridge is generally by five big portions
Part and five widgets are constituted, and five big parts refer to that bridge bears the spanning superstructure of automobile or other vehicle transport loads with
Portion's structure, be bridge structure safe guarantee include bridge span structure (or bridge opening structure superstructures), bridge pad system,
Bridge pier, abutment, cushion cap, dig a well or pile foundation.Five widgets refer to part directly relevant with bridge service function, and the past is referred to as bridge
Surface construction includes deck paving, waterproof and water drainage system, railing, expansion joint, lighting.Large bridge accessory structure also has end of the bridge
Fort, access bridge etc. are set.
With the development and the raising of construction standard of transportation, bearing in bridge and Other Engineering not only
Play a supporting role, but also with vibration damping, resistance to plucking, the effect for discharging moment of flexure, resist displacement.At present, occur often in earthquake pre-
The situation that bridge plate processed falls from bridge pier beam, be the reason for bridge plate falls from bridge pier beam, when there is earthquake,
Very big horizontal force and vertical force is generated, makes precast bridge plate occurred level displacement and upper and lower displacement, when displacement exceedes in advance
Bridge plate processed on bridge pier shelve width after, bridge plate will fall, and now, not only bridge is damaged, Er Qieqiao
Pedestrian and vehicle under upper, bridge occur serious accident.
Accordingly, it would be desirable to a kind of can effectively block the damping due to rotation formula bridge that vibration is transmitted from bridge pier to bridge in earthquake
Damping device.
The content of the invention
In view of this, the purpose of the present invention is to overcome defect of the prior art, there is provided one kind can be effective in earthquake
Block the damping due to rotation formula bridge aseismic devices that vibration is transmitted from bridge pier to bridge.

The beneficial effects of the invention are as follows：Damping due to rotation formula bridge aseismic devices of the invention, pedestal can be fixed on bridge pier,
Supporting plate is used for supporting bridge, and supporting plate is supported by multiple damping wheels simultaneously, and damping wheel passes through damper and damping spring edge
Vertical direction is supported, and so as to realize buffering and damping action of the supporting plate in vertical direction, the vehicle on bridge causes bridge small
During amplitude vibrations, bridge will drive supporting plate to vibrate in the horizontal direction, and this will drive damping wheel to rotate, and damping wheel passes through planet tooth
The rotating speed of damping wheel is amplified (now planet carrier is engaged with pedestal makes it keep fixing) by wheel mechanism, and drives damping shaft to rotate,
Barrel-type casing is securable to bridge pier, and damping shaft is rotated relative to barrel-type casing, effect of the gear piece on damping shaft in magnetic flow liquid
Lower generation damping force, the damping force will hinder the rotation of damping wheel and finally hinder the horizontal vibration by a small margin of bridge, work as generation
During earthquake, ground drives bridge pier that violent oscillatory motion occurs, and bridge will drive damping wheel to rotate, and now go with the horizontal movement of bridge pier
The planet carrier of star gear mechanism and base-separation, planet carrier are free to rotate, therefore the rotation of damping wheel will only drive planet carrier
Idle running, damping wheel will not be subject to any damping action, and now, the vibration of bridge pier will not be passed up to bridge, it is ensured that bridge exists
Will not be destroyed in earthquake.
