When bearing is subject toThe transmission of La Shili: building and upper junction plate (power is upwards) → steel column and location-plate and limiting plate (power is upwards) →Moving lever and tension tighten up screw rod (power is downward) → moving lever support (power is downward) → bedplate and ground.
5, the self-starting principle of shock insulation: in the time that horizontal seismic force acquires a certain degree (earthquake of 4-5 level), due to place kickBearing 12 (steel ring) is little, and place kick 11 (steel ball) is large, place kick 11 horizontal position poor stabilities, place kick 11 HesPlace kick bearing 12, ball cover plate 4 can not be synchronized with the movement, and place kick 11 tumbles ball lid from place kick bearing 12On plate 4, reset pilot pin 10 loses support, and at Action of Gravity Field downslide eject lever locating hole, positioning function is removed, everyShake function on. Big or small when constant when place kick 11, the stability of place kick 11 depends on the large of place kick bearing 12Little, i.e. greatly good stability of place kick bearing 12, the little poor stability of place kick bearing 12.
6, reset principle: reset rubber 8 is connected on upper junction plate 1 above, is connected on moving lever 15 below, byHave certain elasticity in reset rubber 8, in the time of upper junction plate 1 after shake and the 15 generation dislocation of moving lever, reset rubber 8 is carriedThe restoring force of confession makes building return to original state. On reset rubber 8, can leave vertical hole, the inside inject lead for retractable pencil withVibration while increasing deattenuation reset, the while can also regulate the damping ratio of bearing, makes bearing reach best shock insulation state.
7, the operation principle of reset pilot pin 10: reset pilot pin 10 is shuttle type, its middle part is cylinder, one end isCone, the other end is round platform, cone and middle part cylinder are connected, and on the bottom surface axle center of round platform, are provided with threaded rod,Round platform is connected with the screwed hole in cylinder axle center, middle part by threaded rod; Round platform one end of reset pilot pin 10 is arranged on fixedThe top of position ball 11, cone one end of reset pilot pin 10 enters spacing locating dowel 9 through the locating hole of location-plate 3Post locating hole; The effect of upper end cone: due to the load of wind, and the damage etc. of bearing when aging, the earthquake of bearingFactor, the original reset function of bearing can not allow building reset completely after shake, post locating hole and plate locating hole axiallyNot point-blank, the column part of reset pilot pin 10 can not enter bar locating hole to center line. Now can drive except multiplePosition pilot pin 10 bottom round platforms, by jack make to reset stressed the moving up in middle and upper part of pilot pin 10, centrum inclined-plane sideTo squeezing rod locating hole import department, (the micro-funnel type of import department, reduces extruding centrum inclined-plane is caused to damage, avoids increasing multiplePosition difficulty), allow building produce horizontal shift to resetting completely, continue upwards column part upper end and enter post locating holeAfter complete reset and positioning function. The effect of middle part cylinder: the upper end of column part is in post locating hole, and lower end is fixed at plateIn hole, position, when while making to shake, motionless layer is with shake, mobile layer cannot produce dislocation, and opposing wind and other External Force Actings keep buildingStablizing of thing. The effect of lower end round platform: under the little shake state of the favourable maintenance of plane, place kick is stable, and the end face of round platform is little,Can contact area little with place kick 11, can keep reaching 4-5 grades of earthquakes time, place kick 11 can property not stable in performance,Be conducive to the startup of shock insulation function. In the time that place kick 11 is rolled from place kick bearing 12, reset pilot pin 10 is done by gravityWith decline, round platform inclined-plane lateral compression place kick 11, can make it to roll decentre position and further be beneficial to the fast of shock insulation functionSpeed starts.
