Novel friction pendulum support
The invention relates to the technical field of bridge engineering, and particularly discloses a novel friction pendulum support which comprises a bottom plate, a locking mechanism, a reset device and a support assembly. The locking mechanism comprises an elastic clamping tooth part, a rack plate used in cooperation with the elastic clamping tooth part and a trigger locking device. The support assembly comprises a first curved surface sliding pair, a second curved surface sliding pair, a third plane sliding pair and an anti-shearing assembly used for restraining the first curved surface sliding pair. Under a normal working condition, the anti-shearing assembly restrains the first curved surface sliding pair. Under the earthquake working condition, the trigger locking device is locked, the rack plate and the elastic clamping tooth part interact to enable a third plane sliding pair to be restrained, meanwhile, the anti-shearing assembly is sheared off, and the first curved surface sliding pair is released. After the earthquake is finished, the reset device drives the elastic clamping tooth part to move towards one side close to the support assembly, the locking device is triggered to recover to the initial state, and reset is completed. Compared with a traditional speed locking type friction pendulum support, the novel friction pendulum support is better in economical efficiency and durability, and resetting can be effectively achieved.
本发明涉及桥梁工程技术领域，具体公开了一种新型摩擦摆支座，包括底板、锁定机构、复位装置、以及支座总成；锁定机构包括弹性卡齿部、与弹性卡齿部配合使用的齿条板、以及触发锁定装置；支座总成包括曲面滑动副一、曲面滑动副二、平面滑动副三以及用于约束曲面滑动副一的抗剪组件；正常工况下，抗剪组件对曲面滑动副一进行约束；地震工况下，触发锁定装置锁定，齿条板与弹性卡齿部相互作用使得平面滑动副三被约束，同时抗剪组件剪断，释放曲面滑动副一；地震结束后，复位装置驱动弹性卡齿部向靠近支座总成一侧运动，触发锁定装置恢复到初始状态，完成复位。本发明相较传统的速度锁定型摩擦摆支座经济性和耐久性更好，并能够有效的实现复位。
