By said structure, upper anchor plate assembly 4 can rotate relative to end basin 2, the most then can be with end basin 2
Move together.End basin 2 then can move along the relative lower slider plate 1 of track-type facilities 6 in the horizontal direction, therefore goes up anchor plate assembly 4 He
Cylinder body 31 also can move relative to lower slider plate 1 in the horizontal direction.
In such scheme, bottom lower slider plate 1, it is provided with the many pad rod irons 12 that cast anchor, during installation, the many pad rod irons 12 that cast anchor
Stretch into inside bridge pier column, this bearing is fixed on pier stud.
In such scheme, track-type facilities 6 includes the guide-track groove 11 being arranged on lower slider plate 1 and is fixed on bottom end basin 2
Guide rail 24, described guide rail 24 is positioned at guide-track groove 11 and can slide by opposite rail groove 11, and then when bearing low speed horizontal loading
End basin 2 is made relatively to slide by lower slider plate 1.
In such scheme, end basin 2 is respectively provided on two sides with a pair outward extending wing plate 22, the cylinder body 31 of fluid linking damper 3
Be fixed between a pair wing plate 22, be positioned on two wing plates 22 of the same side and have coaxial through hole 23, through hole 23 axis with lead
The axis of rail device 6 is parallel, and described lower slider plate 1 is provided with fixed block 13, the work of fluid linking damper 3 with wing plate 22 correspondence position
Stopper rod 32 two ends are each passed through that described through hole 23 is fixing with described fixed block 13 to be connected.Cylinder body 31 is arranged at two wings of the same side
Between plate 22 so that cylinder body 31 can move with end basin 2；The two ends of piston rod 32 are each passed through wing plate 22 and are connected to fix
On block 13 so that piston rod 32 can move with lower slider plate 1.Piston rod 32 can move by opposing cylinder 31, therefore when end basin 2
During relative to lower slider plate 1 horizontal movement, wing plate 22 can promote cylinder body 31 to move relative to piston rod 32.
In such scheme, upper anchor plate assembly 4 includes anchor pad rod iron 43 on piston 41, upper anchor plate 42 and Duo Gen, described
Being positioned at groove 21 and spherical crown 5 mating spherical surfaces of end basin 2 bottom piston 41, the center of upper anchor plate 42 is provided with pin-and-hole, shear pin 7
Extending in this pin-and-hole, upper anchor plate 42 is fixed on piston 41 top by shear pin 7, and described upper anchor pad rod iron 43 is fixed on
Anchor plate 42 top, during installation, upper anchor pad rod iron 43 extend into inside beam body.
In such scheme, cylinder body 31 two ends are provided with end cap 33, and for closed cylinder 31, described piston rod 32 two ends are from end cap
33 stretch out, and are provided with the annular piston body 34 of evagination in the middle part of described piston rod 32, and piston body 34 is positioned in cylinder body 31 and is divided into
One chamber 36 and the second chamber 37, piston body 34 is communicated with the multiple trickle damping of the first chamber 36 and the second chamber 37
Hole 35, fills damping fluid 38, piston rod 32 horizontal movement in cylinder body 31 in first chamber 36 and the second chamber 37 of cylinder body
Time, in the first chamber 36 and the second chamber, the damping fluid 38 of 37 mutually can be flowed by damping hole 35.In the present embodiment, damping
Liquid 38 is dimethicone.
In such scheme, between upper anchor plate assembly 4 and spherical crown 5, between spherical crown 5 and end basin 2, end basin 2 and lower slider plate 1
Between be equipped with friction pair 8.
After this utility model is arranged between beam body and pier stud, when beam body has slight phase in the horizontal direction relative to pier stud
To motion time, such as due to temperature Change produce bridge stretch, end basin 2 together with upper anchor plate assembly 4 relative to lower slider plate 1
The level produced is slided more slowly and soft, and suffered load is low speed load.Now, the damping fluid 38 in cylinder body 31 is permissible
Flow to the second chamber 37 by damping hole 35 lentamente from the first chamber 36, or flow to first lentamente from the second chamber 37
Chamber 36.Thereby, the piston body 34 on piston rod 32 can move horizontally relative to cylinder body 31, thus allows that bearing is in level
Direction produces slides relatively.
When there is earthquake, the horizontal loading suffered by bearing of the present invention is high speed load, and piston body 34 has relative to cylinder
The trend that body 31 quickly moves, but owing to damping fluid 38 cannot run through damping hole 35 at two chamber indoor moveables, Zhi Nenghuan
Slow flow, thus piston body is formed the most reversely resistance, it is achieved microinching consumes energy, and reaches to maximize earthquake energy
Purpose.
Above content is to combine the further description that the present invention is done by specific embodiment, it is impossible to assert this
Bright being embodied as is confined to these explanations.For the those of ordinary skill of the technical field belonging to the present invention, not
