The invention provides an elevator anti-falling device. The device comprises a platform, a support arranged on the platform, a motor arranged on the support, a first double-chain roller, a second double-chain roller, a first tensioning wheel shaft, a second tensioning wheel shaft, a third tensioning wheel shaft and a fourth tensioning wheel shaft. Chain wheels on the first double-chain roller andthe second double-chain roller are connected with the first tensioning wheel shaft, the second tensioning wheel shaft, the third tensioning wheel shaft and the fourth tensioning wheel shaft which vertically correspond to one another through transmission belt strips respectively. A lifting table is arranged on the transmission belt strips, and the motor is in transmission connection with the firstdouble-chain roller and the second double-chain roller. Firstly, braking is reliable, double sensors are powered on by electric signals for braking, once the sensors sense that the signals exceed therange, a tensioning motor loosens a tensioning rope, an induction female base is connected with an induction plug under the action of the spring, a braking device brakes, and motor operation is more reliable. Secondly, the response is fast.
本发明提出了一种升降机防坠落装置,包括平台、设在平台上的支架,设在支架上的电机、第一双链滚筒、第二双链滚筒、第一张紧轮轴、第二张紧轮轴、第三张紧轮轴、第四张紧轮轴,第一双链滚筒、第二双链滚筒上的链轮分别通过传动带条与上下对应位置的第一张紧轮轴、第二张紧轮轴、第三张紧轮轴、第四张紧轮轴连接,升降台设在传动带条上,电机与第一双链滚筒、第二双链滚筒传动连接;其一是制动可靠,二重传感器加电信号制动,一旦传感器感检测到信号超范围,张紧电机松开张紧绳,在弹簧作用下感应母座与感应插头接合,制动装置制动,电机操作更加可靠;其二响应迅速。
