Vertical shock isolation device
The invention relates to a vertical shock isolation device, and belongs to the technical field of shock isolation/vibration reduction. The vertical shock isolation device comprises an annular spring and a guide sleeve, and the annular spring is arranged in the guide sleeve; and the annular springs comprise a first group of annular springs and a second group of annular springs, the outer diameter of the second group of annular springs is smaller than the inner diameter of the first group of annular springs, and the first group of annular springs, the second group of annular springs and the guide sleeve are coaxially arranged. The first group of annular springs and the second group of annular springs are formed by alternately overlapping a plurality of inner rings and outer rings up and down, the inner rings are gasket-shaped spring steel with inner cylindrical surfaces and outer conical surfaces, and the outer rings are gasket-shaped spring steel with inner conical surfaces and outer cylindrical surfaces. The vertical shock isolation device can effectively isolate the vertical earthquake or vibration effect, and the engineering requirements are met.
本发明涉及一种竖向隔震装置，属于隔震/减振技术领域。该竖向隔震装置包括环形弹簧和导向套筒，所述环形弹簧设置在所述导向套筒内；所述环形弹簧包括第一组环形弹簧和第二组环形弹簧，所述第二组环形弹簧外径小于第一组环形弹簧内径，所述第一组环形弹簧、第二组环形弹簧与导向套筒同轴设置。所述第一组环形弹簧和第二组环形弹簧均由多个内环和外环上下交替叠加而成，内环为内圆柱面外圆锥面的垫圈状弹簧钢，外环为内圆锥面外圆柱面的垫圈状弹簧钢。本发明装置能有效隔离竖向地震或振动作用，满足工程需求。
