摘要
本文根据对海洋石油116装置吊机限位保护系统现状的分析,提出了三个限位保护系统优化的方法。第一,通过增加接近开关保护实现吊臂限位保护逻辑优化;第二,通过修改PLC控制逻辑取消变幅强制功能的方式实现吊机吊臂的限位旁通方式设置优化;第三,通过改变吊机信号旁通管理程序实现旁通管理优化。三个限位保护系统优化增强了吊机运行的安全性。
Based on the analysis of the current situation of crane limit protection system in "Hai Yang Shi You 116", three optimization methods of limit protection system are put forward in this paper. Firstly, boom limit protection logic optimization is realized by adding proximity switch protection. Secondly, the optimization of limit bypass mode of crane boom is realized by modifying the PLC control logic to cancel the variable amplitude coercive function. Thirdly, bypass management optimization is realized by changing the bypass management procedure of crane signal. After optimizing the limit protection system of crane, the safety and stability of crane operation have been improved.
