The emergency braking device for elevator safety comprises a traction motor, the traction motor is fixedly connected with a workbench through a machine base, the traction motor and a traction disc are arranged in a transmission mode through a reduction gearbox, meanwhile, a detection hole is formed in the surface of the traction disc, and a detection device is installed on the workbench; a control box is installed at the bottom of the workbench, an uninterruptible power supply is installed in the control box, meanwhile, a contactor is installed on the upper left side of the uninterruptible power supply, and a relay is installed on the upper right side of the uninterruptible power supply. According to the emergency braking device for elevator safety, under the condition that an elevator runs abnormally, if the optoelectronic switch suddenly detects that the running speed of the traction disc exceeds 110% of the normal running speed of the elevator, the detection plate immediately controls the relay to stop output, the contactor loses power, the braking loop of the traction machine brake is disconnected, the brake acts, and the elevator is immediately braked; and passengers in the elevator are protected.

    本发明公开了一种电梯安全用紧急制动装置,包括:曳引电机,所述曳引电机通过机座与工作台固定连接,且曳引电机通过减速箱与曳引盘传动设置,同时曳引盘的表面开设有检测孔,并且工作台上安装有检测装置,工作台的底部安装有控制箱,且控制箱的内部安装有不间断电源,同时不间断电源的左上侧安装有接触器,并且不间断电源的右上侧安装有继电器。该电梯安全用紧急制动装置,电梯在非正常运行的情况下,光电开关突然检测到曳引盘的运行速度超过电梯正常运行速度的110%,则检测板马上控制继电器停止输出,接触器失电,曳引机制动器的制动回路断开,制动器动作,马上制停电梯,对电梯内部的乘坐人员进行保护。
