Three-dimensional seismic mitigation and isolation support
The invention discloses a three-dimensional shock absorption and isolation support which comprises a base, a lead core rubber support, a belleville spring set and a torsion reed damper, the torsion reed damper comprises a damper sleeve, a flat spiral reed, a ball screw and a lead screw nut block, the ball screw and the lead screw nut block form a ball screw pair, the lead screw nut block is sleeved with the damper sleeve, and the lead screw nut block is sleeved with the belleville spring set. The lead screw nut block rotates in the damper sleeve and is relatively and fixedly connected with the damper sleeve in the axial direction, the bottom end of the damper sleeve is fixed to the base, the inner end of the flat spiral reed is fixed to the lead screw nut block, the outer end of the flat spiral reed is fixed to the inner wall of the damper sleeve, and the bottom end of the lead core rubber support is fixed to the base. The damper sleeve is sleeved with the belleville spring set, the belleville spring set is supported on the lower supporting plate, the lower supporting plate is connected with the top ends of the lead core rubber supports, and the upper supporting plate is arranged at the top end of the belleville spring set and fixedly connected with the top end of the ball screw. The height of the support can be effectively reduced, the stability of the support is improved, and the shock insulation effect is improved.
本发明公开一种三维减隔震支座，包括底座、铅芯橡胶支座、碟形弹簧组和扭转簧片阻尼器，扭转簧片阻尼器包括阻尼器套筒、平面涡卷簧片、滚珠丝杠和丝杠螺母块，滚珠丝杠和丝杠螺母块构成滚珠丝杠副，丝杠螺母块外套设阻尼器套筒，丝杠螺母块转动于阻尼器套筒内，并在轴向与阻尼器套筒相对固定连接，阻尼器套筒底端固定在底座上，平面涡卷簧片的内端固定在丝杠螺母块上，外端固定在阻尼器套筒内壁，铅芯橡胶支座底端固定在底座上，碟形弹簧组套设于阻尼器套筒外，并支撑于下支撑板上，下支撑板与各铅芯橡胶支座顶端连接，碟形弹簧组顶端设置上支撑板，上支撑板与滚珠丝杠顶端固定连接。本发明可以有效降低支座高度，提升支座稳定性，提升隔震效果。
