Said numerical control jack is through the hydraulic jack of power and the opening and closing of recoil simulator control flap valve, has the function of the initial level of formation shock isolating pedestal to locking and release under prescribed condition, and its end that links to each other with driven rod is provided with a hinge ring.
Said numerical control jack adopts number-controlled large-tonnage hydraulic jack, is the best with slim top, like the slim top of YZB/RCS/RSM.
Said shock isolating pedestal is the lead core stacking rubber earthquake isolation support of square sectional, and the length of side is 20cm, and thickness is 80cm, is formed by 100 layers of rubber layer and 100 layers of steel plate arranged alternate, and the centre has vertical through hole, and the circular lead for retractable pencil rod of diameter 5cm vertically inserts wherein.
Said concrete bearing is a reinforced concrete structure, is seated on the ground of building.
Said superstructure base plate is a steel concrete raft plate.
The remarkable result of the utility model is:
(1) " steel plate-driven rod-dividing plate is advanced in resistance " forms initial level to shock isolating pedestal to locking, promptly when original state, shock isolating pedestal in level to moving.When being no more than antidetonation benchmark acceleration, shock isolating pedestal only plays the effect of common bearing, can not cause breaking of pipeline because of big basic displacement;
(2) effect that steel plate also plays the protection shock isolating pedestal is advanced in resistance, can prevent that the external world from flying thing shock isolating pedestal is damaged;
(3) four numerical control jack be arranged in isolate bearing around, distribute with 90 ° of spacings.After the initial level lockout of a horizontal direction, if the earthquake acceleration of another horizontal direction does not surpass benchmark antidetonation acceleration, then the initial lock of this horizontal direction still can work on;
(4) acceleration transducer degree of will speed up signal feedback is given power and recoil simulator, the work of power and recoil simulator control numerical control jack, and the acceleration that is directly obtained by monitoring comes the locking of controlling level direction, need not carry out the stressed inverse of bearing;
This device performance is reliable, easy to maintenance, and earthquake finishes the back only to be needed adjustment numerical control jack and close its flap valve to get final product.
