The invention discloses a quick-response elevator braking device. The device comprises a supporting frame, a brake assembly; a brake wheel and a brake driving assembly, wherein the brake wheel is arranged in the supporting frame, and the brake wheel comprises at least three brake positions arranged on the surface of the brake wheel; the brake wheel is arranged opposite to the other side of an elevator guide rail, and the brake positions and a friction assembly can jointly clamp the elevator guide rail to brake an elevator; the brake wheel comprises a brake wheel shaft and a brake wheel rotation driving device, the brake wheel shaft is rotationally mounted on a mounting seat, and the brake wheel rotation driving device is fixedly mounted on the brake wheel shaft; and the brake driving assembly drives the friction assembly and the brake wheel to be close to or away from the elevator guide rail in the horizontal direction. The response time of the brake device can be shortened, and malfunction of the brake device due to rotation of the brake wheel when the elevator is started and stopped can be prevented. An elevator system is further disclosed.
本发明公开了一种快速响应电梯制动装置,包括:支撑框架;制动组件;制动轮,其设置在所述支撑框架内,所述制动轮包括至少三个设在其表面的制动位置;所述制动轮设置在相对于所述电梯导轨的另一侧,所述制动位置能够与所述摩擦组件共同夹紧所述电梯导轨以使电梯制动;所述制动轮包括制动轮轴和制动轮旋转驱动装置,所述制动轮轴旋转地安装在所述安装座上,所述制动轮旋转驱动装置固定安装在制动轮轴上;制动驱动组件,其驱动所述摩擦组件和制动轮在水平方向上靠近或离开电梯导轨。不仅可以缩短制动装置的响应时间,而且可以防止由于电梯的启停时制动轮旋转导致制动装置误动作。本发明还公开了一种电梯系统。
