Research on Interference Prevention of Cantilever Roadheader Based on Cutting Track

针对巷道施工空间狭小、悬臂式掘进机自动化程度不高的问题,进行了基于截割轨迹的悬臂式掘进机防干涉控制监测一体化系统研究。从悬臂式掘进机机械干涉原理分析入手,分析了防干涉研究存在的不足,并在此基础上,设计出了智能液压限位控制系统。此系统根据记忆程控截割技术记录的截割轨迹控制截割臂和铲板的相对位置,通过传感器传输到操控室,实现可视化监督。此技术的研究改进为悬臂式掘进机机械干涉问题的防治提供了新的思路,以期能够推动悬臂式掘进机向更加智能的方向发展。

Aiming at the small construction space of roadway and the low automation degree of cantilever roadheader,the integrated system of anti-interference control and monitoring of cantilever roadheader based on cutting track is studied. Based on the analysis of mechanical interference principle of cantilever roadheader, the deficiency of anti-interference research is analyzed, and an intelligent hydraulic limit control system is designed. The system controls the relative position of the cutting arm and the shovel plate according to the cutting track recorded by the memory program-controlled cutting technology and transmits to the control room through the sensor to realize visual supervision. The research and improvement of this technology provides a new idea for the prevention and cure of the mechanical interference problem of the cantilever roadheader. Road, with a view to driving the cantilever roadheader to a more intelligent direction.
