Rubber reinforced seismic mitigation and isolation support

CAO LANCHUN / SI GUOCAI / HU ZHIHUI

The invention provides a rubber reinforced seismic mitigation and isolation support, and relates to the field of seismic mitigation and isolation of bridge expansion joints. The farmland water conservancy irrigator with the flow dividing function comprises a fixed bottom plate mechanism, rubber protection pads are fixedly connected to the two sides of the fixed bottom plate mechanism, a lifting mechanism is fixedly connected to the upper end of the fixed bottom plate mechanism, a first motor is fixedly connected to the interior of one side of the lifting mechanism, and a supporting rod is connected to the front end of the first motor in a meshed mode; the other side of the supporting rod is rotationally connected with a supporting plate. The fixing bottom plate mechanism can fix the lower end of a bridge expansion joint through the lifting mechanism and the rubber support body, meanwhile, telescopic rods on the two sides of the fixing bottom plate mechanism can support the front end of the bridge expansion joint, and a linear motor can drive the rubber support body to slide in a sliding plate; and the rubber support body is fixed in the sliding plate through the clamping blocks, so that the rubber seismic mitigation and isolation support is not easy to detect and maintain after being damaged and used.

本发明提供一种橡胶加强型减隔震支座，涉及桥梁伸缩缝减隔震领域。该具有分流功能的农田水利灌溉器，包括固定底板机构，所述固定底板机构两侧均固定连接有橡胶保护垫，所述固定底板机构上端固定连接有升降机构，所述升降机构一侧内部固定连接有第一电机，所述第一电机前端啮合连接有支撑杆，所述支撑杆另一侧转动连接有支撑板。本发明中固定底板机构可以将升降机构和橡胶支座本体进行固定桥梁伸缩缝的下端，同时固定底板机构两侧的伸缩杆可以对桥梁伸缩缝前端一个支撑的作用，直线电机可以带动橡胶支座本体在滑动板内部进行滑动，卡块将橡胶支座本体固定到滑动板内部也方便在橡胶减隔震支座损坏和使用后不易对橡胶减隔震支座进行检测和维修。
