Bridge shock isolation and absorption soft steel damping device
The invention, which relates to the technical field of bridge damping devices, discloses a bridge shock isolation and absorption soft steel damping device comprising a bridge body. A damping spring ismovably connected to the interior of the bridge body; the surface of the damping spring is fixedly connected with a guide rod, the top of the guide rod is movably connected with a supporting rod, thesurface of the supporting rod is movably connected with a clamping groove; the side, away from the supporting rod, of the clamping groove is movably connected with an anti-torsion box, the surface ofthe anti-torsion box is movably connected with a buffer bag, and the top of the buffer bag is movably connected with a rotating shaft. Therefore, the supporting rod in the bridge body can be extruded; the supporting rod is designed into an inclined plane, so that the limiting force on the damping spring at the bottom of the guide rod can be reduced in the moving process of the support rod; and thus the damping spring releases an elastic force to push the supporting rod to move and rotate upwards at the same time. A phenomenon of pushing a protruding plate away from the bridge body surface isshown in a figure 4, so that the longitudinal load is controlled according to the strength of transverse vibration to separate the bridge and thus the bridge body is protected from being broken and the vehicle safety is protected.
本发明涉及桥梁阻尼装置技术领域，且公开了一种桥梁隔减震软钢阻尼装置，包括桥体，所述桥体的内部活动连接有减震弹簧，减震弹簧的表面固定连接有导向杆，导向杆的顶部活动连接有支撑杆，支撑杆的表面活动连接有卡槽，所述卡槽远离支撑杆的一侧活动连接有抗扭箱，抗扭箱的表面活动连接有缓冲囊，缓冲囊的顶部活动连接有转轴。故会挤压桥体内部的支撑杆，且支撑杆为斜面设计，故支撑杆移动的过程中会减少对导向杆底部的减震弹簧的限制力，即减震弹簧释放弹力推动支撑杆边移动边向上转动，将凸起板推离桥体表面如图4所示，从而达到了根据横向震动的力度控制纵向载荷的大小使桥梁分离、保证桥体不会断裂且保护车辆安全的效果。
