Buffering energy dissipation beam falling prevention device
The invention belongs to the technical field of bridge engineering, and discloses a buffering energy consumption anti-beam-falling device which comprises a mounting bottom plate, energy consumption plates are arranged on the mounting bottom plate, every two energy consumption plates form a group, the horizontal distance of each group of energy consumption plates is adjustable, friction sliding grooves are formed in the opposite faces of the energy consumption plates, and the groove length of each friction sliding groove horizontally extends and is perpendicular to the distance adjusting direction. An energy consumption sliding block is arranged between the energy consumption plates, friction protruding blocks are arranged on the two sides of the energy consumption sliding block, the energy consumption plates penetrate through the rod-shaped component, and the axis direction of the rod-shaped component is parallel to the distance adjusting direction of the energy consumption plates. The rod-shaped component is provided with an elastic reset assembly for pressing the friction sliding groove on the friction protruding block, the energy consumption sliding block is provided with a strip-shaped through hole for the rod-shaped component to penetrate through, and the end of the energy consumption sliding block is provided with a collided part for a preset steel arm to collide. The self-resetting device has the working characteristics of first buffering and second braking by means of friction energy consumption, can avoid damage caused by excessive impact, and can be self-reset by means of elastic force.
本发明公开了一种缓冲耗能防落梁装置，属于桥梁工程技术领域，包括安装底板，安装底板上设有两两一组的耗能板，每组耗能板的水平间距可调，耗能板的相向面上设有摩擦滑槽，摩擦滑槽的槽长水平延伸并垂直于间距调节方向，摩擦滑槽由中部至两端槽深逐渐变浅，耗能板之间设置有耗能滑块，耗能滑块的两侧设有摩擦凸块，耗能板通过杆状构件贯穿，杆状构件的轴线方向平行于耗能板的间距调节方向，杆状构件上设有将摩擦滑槽压紧在摩擦凸块上的弹性复位组件，耗能滑块上设有供杆状构件贯穿的条形过孔，耗能滑块的端部设有供预设钢臂撞击的受撞部。依靠摩擦耗能，具有“先缓冲、后刹车”的工作特征，可避免撞击过大而损坏，能够依靠弹性力自复位。
