1, it realizes the lifting of girder horizontal bidirectional, is more applicable for Practical Project and convenient for promoting the use of.
2. the spheroid of Intermediate Gray gear is displaced under severe earthquake action by the engagement of gear, while by
Power area is constant, uniform force, reduces danger of toppling, and limit ellipsoid rotor angle of rotation by gear ring two sides limited block
Degree effectively prevents the phenomenon that being mutually disengaged between different component.
3. making whole device that there is stronger self-resetting capability by the engagement of gear under the effect of gravity.4. support plate with
It is laid with rubber layer between limit plate, is connected by tiny card slot, robber cement, which is heaved, moves energy consumption, reduces earthquake displacement response, limit
Circle limitation rubber alternate displacement, prevents element falling.
5. Gong She tri- prevents element falling: upper limit circle, limited block, lower limit circle, it is ensured that whole device is high
Security performance.
6. being equipped with the transverse shearing stress that protrusion mitigates bolt under earthquake load at limit plate peg, the strong of connector is improved
Degree.
It 7. the present invention meets multi-level heating net requirement, can satisfy work requirements when normal work, can also meet under small shake
By shear connector limiting displacement, the energy consumption demand of girder is lifted under macroseism by ellipsoid rotor.
8. the gap between rubber layer and spacing collar is deformed to adaptive temperature, meet the needs of normal work.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
Referring to Fig. 1-7.
The invention discloses a kind of three-dimensional gear type Self-resetting energy consumption shock isolating pedestals, including are successively upper limit from the top down
Plate, upper rubber layer, upper bracket plate, band tooth ellipsoid rotor, lower support plate, lower rubber layer, upper undersetting described in lower limiting board are logical
It crosses and more shear connectors are set are connected, be provided with rubber seal on the outside of shear connector.
Further, the upper limit plate is connected by peg with girder, and the lower limiting board is connected by peg with bent cap.

Further, spacing collar length is greater than rubber layer thickness, and there are a fixed gaps between spacing collar and rubber layer.
Use principle of the invention is summarized as follows:
Under normal utilization, vertical deformation is resisted in the supporting role of ellipsoid rotor and the restraining force of shear connector is resisted laterally
Deformation, the gap between rubber layer and spacing collar are strained to adaptive temperature, and whole device is made to maintain to stablize.
In the case of small shake, rotor weak vibrations, two sides shear connector limiting displacement has ellipsoid rotor and upper undersetting concurrently
The ratcheting supporting role of plate makes whole device maintain to stablize.
In the case of big shake, two sides shear connector is destroyed, and band tooth ellipsoid is moved under active force by gear engagement
Position, upper beam are elevated, and by converting kinetic energy into gravitional force, realize support energy consumption.Later, due to gravity, band tooth is ellipse
Ball engages automatic homing by gear, completes entire Self-resetting energy consumption process.
After shake, replacement shear connector restores to use.
It is described further,
As shown in fig. 6, system remains stable substantially under the normal application of structure and in the case of small shake.
If figure five is to shown in Fig. 7, when structure meets with macroseism, rotor is under active force relative to undersetting and upper bracket
It swings, active force is larger at this time, and shear connector fracture, rotor is rotated by gear engagement, raises upper bracket.Outer ring
It is provided with limited block, when rotating to a certain degree, block provides constraints, and is forced to stop operating.After shake, under the effect of gravity,
Rotor restores initial state automatically.
After shake, it is only necessary to which replacing shear connector can restore rapidly to use.
