Shock absorption and isolation device for power transmission tower foot
The shock absorption and isolation device comprises an upper top plate, a lower bottom plate and a shock absorption and isolation support, the shock absorption and isolation support comprises an upper bearing plate, a lower bearing plate and a corrugated flexible protection shell, the two ends of the corrugated flexible protection shell are connected with the upper bearing plate and the lower bearing plate correspondingly, a sliding block body is arranged in the corrugated flexible protection shell, and a pivot ball is arranged on the bottom face of the upper bearing plate; the ball portion of the pivot ball is embedded into the containing cavity of the sliding block body and freely rotates in the containing cavity, the bottom face of the sliding block body is provided with a limiting portion and a sliding groove, a sliding pedestal is arranged below the sliding groove in a matched mode, the top face of the sliding pedestal is concaved inwards to form a limiting groove in the center position, and the limiting portion of the bottom face of the sliding block body is arranged in the limiting groove. Sliding rolling balls are embedded in the sliding grooves, the bottoms of the sliding rolling balls are tightly attached to the top face of the sliding pedestal, a viscoelastic cushion layer is arranged at the bottom of the sliding pedestal, and the viscoelastic cushion layer, the lower bearing plate and the lower bottom plate are fixedly connected in sequence. Shock absorption and isolation protection of the power transmission tower is achieved, and damage of earthquake disasters to the structure of the power transmission tower is effectively reduced.
本发明提供了一种用于输电塔脚的减隔震装置，包括上顶板、下底板和减隔震支座，减隔震支座包括上承板、下承板和波纹柔性保护壳，波纹柔性保护壳两端分别与上承板和下承板连接，内部设有滑块体，上承板底面设有枢轴球体，枢轴球体的球体部嵌入滑块体的容置腔内，在容置腔内自由转动，滑块体的底面设有限位部和滑动槽，滑动槽下方配套设置滑动台座，滑动台座顶面向内凹陷在中心位置处形成限位槽，滑块体底面的限位部置于限位槽内，滑动槽内嵌有滑动滚球，滑动滚球底部紧贴于滑动台座顶面，滑动台座底部设有粘弹性垫层，粘弹性垫层、下承板和下底板依次固定连接。本发明实现了对输电塔的减隔震防护，有效降低了地震灾害对输电塔结构的损害。
