摘　　要：控制4 300 mm宽厚板剪切线横移台架运输链链臂的液压系统管路及升降限位接近开关装置存在设计缺陷,限位接近开关经常出现信号中断及损坏的情况。通过对液压系统管路及升降限位开关装置进行重新优化改造后,提高了液压缸动作同步性,解决了接近开关信号丢失及损坏的问题,保证了生产顺行,提高了作业效率。There were some design defects in the hydraulic control system for transverse platform chain arm ai^d the lifting limit switch devices, and so the signal interruption and damage of limit proximity switches often occurred. Through anew optimizing and upgrading the hydraulic system pipelines and the lift- ing limit switch devices, the synchronization of hydraulic cylinder movement was improved, the problem of signal loss and damage of proximity switches was solved, then the smooth production was ensured and the operation efficiency was raised.
