地铁隧道多方位高精度钻孔设备的方案设计

摘要

针对地铁隧道内悬挂接触网汇流排安装中钻孔设备施工范围小、效率低、劳动强度大等缺点,设计了一种基于光机电一体化的地铁隧道多方位高精度钻孔设备.介绍了其总体方案、主要结构和控制方案.该钻孔设备采用激光测量仪、角传感器、光学摄像机等实现自动化精密定位,PC机和PLC实现自动化控制,伺服电机、电动缸、回转轴承实现6个自由度的精确调整,适应复杂多变的隧道地形和施工要求.该钻孔设备可安装4个钻机,不仅能向隧道顶部钻孔,还可以任意角度向隧道上部侧壁钻孔.%The lower scope,lower efficiency,higher labour intensity are the main problems existed in the installation of suspension catenary motherboard in subway tunnel.Aiming at which,a new subway tunnel drilling equipment with multi-direction and high precision based on opto-mechatronics integration is designed,the overall plan,main structure and control method of it are introduced.Laser measuring instrument,angle sensors and optical camera are used in this equipment to realise automatic precise positioning,PC and PLC are used to realize automatic control,servo motor,electric cylinder,slewing bearing are used to realize accurate adjustment of six degrees of freedom,so as to adapt to the complex terrain and construction requirements.This equipment installed with 4 drills can drill to the top of the tunnel and drill arbitrary inclined angle holes on the side.
