The invention relates to the technical field of elevator buffer seats, in particular to a movable buffer for an elevator, which comprises an anti-collision pad and two single-side supporting mechanisms, the anti-collision pad is fixedly mounted on a base, and each single-side supporting mechanism comprises a buffer, a swing arm, a torsion spring and a clamping mechanism. The swing arm can be pushed to rotate through the torsional spring, and the swing arm drives the buffer to move to the bottom of a cross beam of an elevator car at a higher speed in a rotating motion mode. And under the condition that the elevator is powered on, the swing arm can be released through the clamping mechanism, so that the swing arm drives the buffer for supporting. And in case of power failure, if the elevator does not fall, the clamping mechanism keeps clamping the swing arm, and falling occurs, the elevator car can drive the clamping mechanism to be separated from the swing arm, so that the device can be used under the condition of power failure, and the elevator car is protected.
本发明涉及电梯缓冲器座技术领域,具体涉及一种电梯用移动式缓冲器,包括固定安装在底座上的防撞垫和两个单边支撑机构,每个单边支撑机构均包括缓冲器、摆动臂、扭簧和卡接机构,该电梯用移动式缓冲器,能够通过扭簧推动摆动臂进行旋转运动,而通过旋转运动的方式,使得摆动臂带动缓冲器能够以更快的速度运动至电梯轿厢的横梁底部。且电梯通电的情况下,能够通过卡接机构进行释放摆动臂,使得摆动臂带动缓冲器进行支撑。而若是发生断电的情况,若是电梯没有发生下坠,卡接机构保持对摆动臂的卡接,而发生下坠,则可以通过电梯轿厢带动卡接机构与摆动臂分离,保证该装置能够在断电的情况下使用,对电梯桥厢进行保护。
