The invention discloses an elevator safety braking device and an elevator, and provides the following technical scheme that the elevator safety braking device comprises a detection mechanism and a parking mechanism which are installed at the output end of an elevator, and the detection mechanism is used for driving the parking mechanism to lock the output end exceeding the preset rotating speed. According to the elevator safety braking device and the elevator, the situation that a sensor detects the abnormal rotating speed of the output end of the elevator through a mechanical structure is abandoned, and when the rotating speed detected by the detection mechanism exceeds the preset rotating speed, the parking mechanism is driven to lock the output end of the elevator, and emergency risk avoiding is conducted.
本发明公开了一种电梯安全制动装置及电梯,本发明提供如下技术方案:一种电梯安全制动装置,包括安装于提升机输出端的检测机构和驻车机构,所述检测机构用于驱动所述驻车机构对超出预定转速的所述输出端进行锁止。本发明提供的电梯安全制动装置及电梯,摒弃传感器利用机械结构检测提升机输出端的异常转速,并当检测机构检测获取转速超过预定转速的时候,就会驱使驻车机构对提升机输出端进行锁止,进行应急避险。
