Mainly include upper bracket plate, lower support plate in structure and be positioned at spherical cap components between the two, upper bracket
The first wearing plate it is provided with, under spherical crown liner plate between plate domed lower surface and the spherical upper surface of spherical crown liner plate
The second wearing plate it is provided with between surface and undersetting upper surface.When bridge temperature deformation makes support displacement
Time beam body have certain lifting, railroad track or highway pavement arching phenomenon, shadow at bearing can be caused
Ring the traffic capacity of road, jump particularly at a high speed car phenomenon；When bridge is because of wind-force, braking, earthquake etc.
Factor can not share horizontal load when producing significant shock.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of without lifting bidirectional damping friction pendulum
Formula bearing, during to eliminate bridge temperature deformation displacement, beam body raises phenomenon, when bridge because of wind-force, braking,
When the factors such as earthquake produce significant shock, part of horizontal load shared by bearing, reduces earthquake to top beam body
The effect destroyed.
It is as follows that this utility model solves the technical scheme that its technical problem used:
Of the present utility model a kind of without lifting bidirectional damping friction pendulum support, including upper bracket plate,
Lower support plate and be positioned at spherical crown liner plate between the two, upper bracket plate lower surface and spherical crown liner plate upper surface
Between there is the first friction pair and be provided with the first wearing plate, in spherical crown liner plate lower surface and lower support plate
There is between surface the second friction pair and the second wearing plate is set, it is characterized in that: described first friction pair,
Second friction pair is sphere friction pair, lower support plate is arranged the second friction pair is formed the horizontal of constraint
Spacing shear pin；Be provided with base plate below described lower support plate, lower support plate bottom surface and plate top surface it
Between form planar slide friction pair be provided with the 3rd wearing plate；Arrange outside the direction across bridge side of lower support plate
Speed lockup's device, speed lockup's device is fixed with lower support plate, base plate and is connected.
The beneficial effects of the utility model are, realize normal design displacement and the rotation of beam body when normality
And do not raise beam body；When bridge is because of factor generation significant shock such as wind-force, braking, earthquakes, plane is sliding
Part of horizontal load is shared in dynamic secondary speed lockup's device locking by being connected on bearing, and curved surface rubs simultaneously
Wipe secondary along longitudinal oscillation power consumption, reduction beam body vibration frequency, reduce the work that top beam body is destroyed by earthquake

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
See figures.1.and.2, of the present utility model a kind of without lifting unidirectional damping friction pendulum support,
Including upper bracket plate 2, lower support plate 6 be positioned at spherical crown liner plate 4 between the two, upper bracket plate 2
There is between lower surface and spherical crown liner plate 4 upper surface the first friction pair and be provided with the first wearing plate 3,
There is between spherical crown liner plate 4 lower surface and lower support plate 6 upper surface the second friction pair and to arrange second resistance to
Nog plate 5.Described first friction pair, the second friction pair are sphere friction pair, and lower support plate 6 is arranged
Second friction pair is formed the cross spacing shear pin 16 of constraint.Arrange below described lower support plate 6
There is base plate 8, form planar slide friction pair between lower support plate 6 bottom surface and base plate 8 end face and arrange
There is the 3rd wearing plate 7.Outside the direction across bridge side of lower support plate 6, speed lockup's device 12, speed lockup are set
Device 12 is fixed be connected with lower support plate 6, base plate 8.
When bearing relative sliding velocity is slow, speed lockup's device 12 is not had an effect, it is allowed to it is certainly
By sliding.When bridge produces significant shock because of factors such as wind-force, brake force, earthquakes, bearing is quick
During slip, speed lock 12 is had an effect, and lower support plate 6 is locked with base plate 8, shares part

Change, do not affect bearing and use.
The above this utility model one that simply explains through diagrams is without lifting bidirectional damping friction pendulum
Some principles of bearing, be not intended to be confined to this utility model shown in and described concrete structure and
In the scope of application, therefore every corresponding amendment being likely utilized and equivalent, belong to this reality
With novel apllied the scope of the claims.
