Shock absorption and isolation device for bridge and usage method of shock absorption and isolation device
The shock absorption and isolation device comprises a cylinder body and a piston rod, a top plate is arranged at the top, extending out of the cylinder body, of the piston rod, and a spring is arranged between the top plate and the cylinder body; an annular groove is formed in the side wall of the lower portion in the cylinder body, a piston, an oil storage cavity and an oil outlet groove are arranged in the cylinder body, an oil outlet hole communicated with the oil outlet groove is formed in the side wall of the cylinder body, and an oil outlet mechanism used for controlling the descending speed of the piston rod is arranged between the oil storage cavity and the oil outlet groove. The invention further discloses a usage method of the shock absorption and isolation device for the bridge. Through the arrangement of the spring and the hydraulic oil way control mechanism, shock absorption and shock isolation are conducted on the situation that shock generated by earthquakes, truck heavy loads and overload exceeds the spring shock absorption range through hydraulic oil way back pressure control and speed control, impact of geological vibration, vehicle loads and the temperature effect on a bridge is avoided, the shock resistance and pressure resistance of the support are improved, and the service life of the support is prolonged. And shear deformation of the support is avoided.
本发明公开了一种用于桥梁的减隔震装置，包括缸体和活塞杆，活塞杆延伸出缸体的顶部设置有顶板，顶板和缸体之间设置有弹簧；缸体内下部侧壁上设置有环形槽，缸体内设置有活塞、储油腔和出油槽，缸体侧壁上设置有与出油槽连通的出油孔，储油腔和出油槽之间设置有用于控制活塞杆下降速度的出油机构；本发明还公开了一种用于桥梁的减隔震装置使用方法；本发明通过设置有弹簧和液压油路控制机构，利用液压油路背压控制以及速度控制，对地震、卡车重载以及超载产生的震动超出弹簧减震范围的进行减震和隔震，解决了地质振动、车辆载荷和温度效应对桥梁的冲击，提高支座抗震抗压能力，避免支座剪切变形。
