Damping structure of bridge expansion joint
The invention discloses a damping structure of a bridge expansion joint. The damping structure of the bridge expansion joint comprises a damping assembly arranged between a first bridge plate and a second bridge plate, and the damping assembly comprises a first fixing box, a first sleeving plate, a first moving rod, a first fixing rod and a first-stage damping part formed by an elastic piece; first-stage damping is carried out under the action of the elastic pieces firstly, second-stage damping is carried out under the action of the second movable rod, and if the first fixed rod makes contactwith the second movable rod, the second fixed rod makes contact with the second fixed box, and hydraulic oil forms second-stage damping. when the first bridge plate or the second bridge plate vibrates, if the first fixed rod makes contact with the first movable rod, the first moving rod is pushed to drive the first sleeving plate to move, so that hydraulic oil is extruded to the second fixing boxfrom the first fixing box, the hydraulic oil drives the second sleeving plate to drive the third moving rod to make contact with the second fixing rod, damping is conducted on the second bridge plateor the first bridge plate, secondary damping is achieved, the damping effect is good, and the structure is simple; installation is convenient, and damping cost is saved.
本发明公开了一种桥梁伸缩缝的减震结构，包括在第一桥板和第二桥板之间设置的减震组件，减震组件包括第一固定箱、第一套装板、第一移动杆、第一固定杆和弹性件形成的一级减震，以及第二套装板、第二移动杆、第三套装板、第三移动杆、第二固定杆、与第一固定箱连通的第二固定箱和液压油形成的二级减震，在第一桥板或第二桥板震动时，首先在弹性件作用下进行一级减震，若第一固定杆和第一移动杆相接触时，会推动第一移动杆带动第一套装板运动，从而将液压油从第一固定箱挤压至第二固定箱，液压油驱动第二套装板带动第三移动杆与第二固定杆接触，对第二桥板或第一桥板进行减震，实现二级减震，减震效果好，结构简单，安装方便和节省减震成本。
