The life and property loss that special violent earthquake causes is startling, if special violent earthquake occurs in nuclear power station region, the consequence causing will be catastrophic.Collection collection in 1999 earthquake causes 2 compressor emergency shutdowns of Taiwan the first nuclear power station; Japan Niigata earthquake in 2007; causing Bai Qi to cut plumage nuclear power station closes; there are 9.0 grades of violent earthquakes in coastal waters, Miyagi Prefecture, Japan in 2011; cause 4 units of Fukushima nuclear power station to be blasted; cause serious nuclear leakage accident, the economy causing, environmental loss are difficult to estimate.
Current nuclear power station structure design is still take traditional anti-seismic technology as main, emerging earthquake isolation technology lags behind with application is serious in the research in nuclear power station structure field, in the whole world all commercial off-the-shelfs nuclear power plant, only have two to use base isolation technology up to now.Within 1977, first rubber isolator is used for to the Koeberg nuclear power station in South Africa, within 1984, is applied to French Cruas nuclear power station.Shock insulation can effectively reduce the acceleration earthquake reaction of nuclear island, but the over-large displacement of Seismic Isolation of Isolation Layer may cause passing in and out nuclear island line break simultaneously, easily causes secondary destruction.This becomes the key issue that restriction seismic isolation technology is applied in nuclear power structure.
Summary of the invention
The defect existing for prior art, the object of this invention is to provide a kind of horizontal shear locking earthquake isolating equipment, for the shock insulation design to Seismic Isolation of Isolation Layer displacement Sensitive Buildings structure, make nuclear power station isolation structure under small earthquakes effect, by superstructure opposing geological process, earthquake isolating equipment is in blocking, when large shake carrys out interim blocking device release, shock isolating pedestal enters work, guarantees the safety of superstructure by the level of shock isolating pedestal to distortion earthquake energy.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of horizontal shear locking earthquake isolating equipment, comprises rubber earthquake isolation support, shears blocking device, steel plate, sheet rubber, upper junction plate and lower connecting plate; Shown in being arranged in, described steel plate and sheet rubber intersecting in rubber earthquake isolation support, make steel plate and sheet rubber bonding by sulfuration process; Described shearing blocking device hoop on described rubber earthquake isolation support, make rubber earthquake isolation support in level to locking; Described rubber earthquake isolation support is fixed by upper junction plate and superstructure, fixing by lower connecting plate and basis.
Further, described rubber earthquake isolation support center is reserved with lead for retractable pencil hole.
Further, described shearing blocking device comprises the four block-shaped steel members that are quadrant arc, and high-strength shear key and nut; Described steel member one end is provided with groove, and the other end is provided with projection, and is provided with at groove, high spot the fixing hole being parallel to radially; By mutually chimeric to the groove of four blocks of steel members and projection, described high-strength shear key is passed to fixing hole, and fix by nut, form closed shearing blocking device, shear the internal diameter of blocking device and the external diameter of rubber earthquake isolation support and equate; On the inwall of steel member, have hoop dead slot, by the duty of hoop dead slot monitoring rubber earthquake isolation support.
Further, according to the chimeric position of the groove of described steel member, projection default two weak sections on high-strength shear key, guarantee that section when high-strength shear key is cut off is positioned at two weak sections.
Compared with prior art, the utlity model has following outstanding advantage:
1) solved in, under small earthquake effect, thereby the excessive problem that causes line fracture to cause secondary destruction of shock insulation nuclear power station Seismic Isolation of Isolation Layer displacement, and blocking device release under large shake effect, shock isolating pedestal enters consumption in operation seismic energy.
2) can change the lock-in threshold of blocking device by the material, quantity, size and the weak section diameter that regulate high-strength shear key, thereby reach designing requirement.
3) vertical force of superstructure is still born by shock isolating pedestal, and additional shearing blocking device does not change seating plane presses, without adjusting shock insulation design.
4) after blocking device release, high-strength shear key is cut off, and arc-shaped steel member is open but does not damage, and after shake, can reuse.
