悬臂式掘进机断面轮廓监控系统

Section profile monitoring system for boom-type roadheader

为了有效控制掘进机截割断面的准确性,建立了截割机构工作参数和巷道断面尺寸关系的数学模型,推导了悬臂转角、液压缸行程及截割头空间坐标的位置关系,并以8051f系列单片机为核心,开发了悬臂式掘进机断面轮廓的监控系统。该系统能够根据传感器采集的实时数据,精确控制悬臂的摆动行程,及时准确地计算截割头的位置和断面截割情况,实现了巷道断面截割的自动控制。

Aimed at the effective control section profile accuracy of a roadheader, this paper introduces a mathematical model designed for relation of work parameters of a cutting mechanism to section sizes of a roadway. The relation between cantilevered comer, the fuel tank trip and cutting head space location is deduced. A monitoring system capable of controlling the cutting size by 8051f MCU is developed. The system allows real-time data to be collected by sensors, the cantilever swing trip to be precisely controlled, cutting head position and cutting section to be calculated on a timely basis, and above all automation excavation to be achieved.
