The invention discloses an elevator rope clamping prevention safety protection system which comprises two rotatable feeler levers, two servo motors, two angle sensors, a comparator, an alarm and a controller. The two feeler levers are installed on an elevator car door on one side at the same time and distributed at the positions, close to the upper corner and the lower corner of a door slot, of the same elevator car door. Each feeler lever is in driving connection with a transmission shaft of a configured servo motor, and the two servo motors are in signal connection with the controller; an angle sensor is further arranged on a transmission shaft of each servo motor in a linkage mode, the two angle sensors are in signal connection with a comparator, the comparator is in signal connection with an alarm and a controller at the same time, and the controller is connected with an elevator control system. The invention belongs to the technical field of safety protection equipment, and solves the problem of safety accidents caused by the fact that a car door system in the prior art cannot identify and prevent flexible rope obstacles with small diameters.
本发明公开了电梯防夹绳安全保护系统,包括两个可旋转的触杆、两个伺服电机、两个角度传感器、比较器、报警器、控制器,该两个触杆同时安装在一边轿厢门上,并且分布在该同一个轿厢门靠近门缝的上下角位置,每一个触杆与所配置的一个伺服电机的传动轴驱动连接,总共两个伺服电机均与控制器信号连接;每一个伺服电机的传动轴上还联动设置有一个角度传感器,总共两个角度传感器均与比较器信号连接,比较器同时与报警器、控制器信号连接,控制器再与电梯控制系统连接。本发明属于安全防护设备技术领域,解决了现有技术的轿厢门系统不能识别、不能防止直径小的柔性的绳类障碍物,从而造成安全事故的问题。
