Pinion and rack type energy dissipation bridge support
The invention discloses a gear rack type energy consumption bridge support, which can consume kinetic energy of horizontal movement of a main beam relative to a bridge tower through an energy consumption unit while meeting the requirement of supporting the main beam on the bridge tower by utilizing a spherical support body, namely provides damping force for the main beam through an upper support plate. The horizontal displacement between the main beam and the bridge tower is effectively inhibited, and the fatigue damage of the bridge support caused by continuous movement of the main beam relative to the bridge tower can be reduced, so that the service life of the bridge support is prolonged, and the maintenance cost is reduced; moreover, the bridge support is divided into the spherical support body and the energy consumption unit which are independently mounted according to a modular design concept, so that the difficulty of mounting and subsequent maintenance work is reduced, and the maintenance cost is further reduced; moreover, by changing the resistance value of the terminal resistor, the damping force can be conveniently adjusted, and convenience is provided for application of the device in engineering practice.
本发明公开了一种齿轮齿条式耗能桥梁支座，在利用球型支座本体满足在桥塔上支撑主梁的需求的同时，通过耗能单元能够消耗主梁相对桥塔水平移动的动能，也即通过上支座板向主梁提供了阻尼力，有效抑制了主梁与桥塔之间的水平位移，能够减轻桥梁支座因主梁相对桥塔持续运动而导致的疲劳损坏，以延长桥梁支座的使用寿命，降低了维护成本；而且，本发明以模块化设计理念将桥梁支座分为球型支座本体和耗能单元该两个独立安装的部分，降低了安装和后续维护工作的难度，进一步降低了维护成本；并且，本发明通过改变终端电阻的阻值，即可以很方便的调节阻尼力的大小，为本发明应用在工程实际中提供了便利。
