The roadheader is composed of cutting part, shovel plate part, first conveyor, body part, walking part, temporary support system, laser detection equipment, rear support, hydraulic system, water system, lubrication system and electrical system. It is a tunneling robot that can make independent decisions and intelligently control. It monitors the force changes of underground rock strata in real time, detects the underground roadway environment, generates surrounding rock and body coordinates independently, and decides the travel route by itself. Among them, the folding mechanical arm of the temporary support system is simple, fast, flexible and efficient, which can improve the safety of workers. Three-dimensional detection automatically positions the tunneling equipment and surrounding rock to realize accurate tunneling. The equipment in the system automatically completes detection, analysis and judgment, Manipulation control, to realize intelligent tunneling.
