The invention discloses an elevator emergency braking safety protection device which comprises a box body. A control cavity is formed in the box body. Control required by the device is achieved through bevel gear transmission according to related knowledge of mechanical transmission, through different rotating speeds of output shafts of a motor rotating in a load state and a non-load state, speedcontrol gears beside the motor mesh with each other under the condition of large centrifugal force and then rotate, through gear and rack meshing transmission, a buffer column ascends to drag a lifting platform sliding from the upper side, and when a fault occurs, tension between a steel cable and the lifting platform almost disappears, the lifting platform and a lifting column are clamped under the action of the elastic force of a spring, so that the lifting platform falls down at a reduced speed.

    本发明公开的一种升降机紧急制动安全保护装置,包括箱体,所述箱体内设有控制腔,本发明根据机械传动的相关知识,通过锥齿轮传动实现装置的所需要的控制,通过电机转动在负荷状态和非负荷状态的输出轴的转速不同,进而使在电机旁的速控齿轮在离心力较大的情况下卡和,进而使之转动,通过齿轮齿条啮合传动,使缓冲柱向上升起拖住上侧滑落的升降升降平台,还有在出现故障时,钢缆和升降平台之间的拉力几乎消失,进而使弹簧弹力的作用下使升降平台与升降柱夹紧,使之减速下落。
