The invention relates to the technical field of slack rope protection, in particular to an all-digital slack rope protection device, which comprises two sets of magnetoelectric encoders respectively mounted on a head sheave and an elevator and used for detecting operation pulses of the head sheave and the elevator in real time; the PLC is installed in a control cabinet of the elevator, pulse data of a head sheave of the magnetoelectric encoder and pulse data of the elevator are received by the PLC through a transmission line, the running speed of the head sheave and the running speed of the elevator are obtained through PLC program calculation and analysis, and whether rope loosening occurs or not is judged according to speed comparison; the control screen is installed in a driver control room and used for displaying the speed values of the head sheave and the elevator in real time, recording the occurrence frequency of the rope loosening phenomenon and providing data for follow-up equipment maintenance and fault analysis; an emergency processing unit; according to the device, through the arrangement of the magnetoelectric encoder, the defects that a traditional mechanical rope loosening protection device is insensitive and unreliable are overcome, and rope loosening accidents caused by the defects of a mechanical device are fundamentally avoided.
本发明涉及松绳保护技术领域,尤其是全数字松绳保护装置,包括:两套磁电编码器,分别安装于天轮和提升机上,用于实时检测天轮和提升机的运行脉冲;PLC,安装于提升机的控制柜内部,磁电编码器的天轮和提升机的脉冲数据通过传输线被PLC接收,经过PLC程序计算分析,得出两者的运行速度,以根据速度对比判断是否发生松绳;控制屏,安装于司机控制室,用于实时显示天轮和提升机的速度值,并记录松绳现象发生次数,为后续设备维护和故障分析提供数据;应急处理单元;此装置通过磁电编码器的设置,摈弃了传统机械式松绳保护装置不灵敏、不可靠的弊端,从根本上避免了因机械式装置缺陷而导致的松绳事故发生。
