Collision detection method for anchor digging machine water drilling rig

Loading water drilling rig on the anchor digging machine can effectively increase the tunneling efficiency. In order to avoid the interference between the water drilling rig and the anchor machine in the working process, it is necessary to calculate the joint variables of the drilling rig accurately. Using the robot kinematics analysis method, the kinematics model of the system is established. At the same time, combined with bounding box collision detection technology, the key parts of the equipment are mathematically modeled. A method for collision detection of onboard water exploration and drainage drilling rig of anchor digging machine is proposed. The simulation results show : The designed collision detection method can be used to guide the attitude adjustment of the equipment during the drilling operation of the equipment, and can accurately analyze the interference characteristics and collision detection of the equipment. It provides a theoretical basis for the automatic excavation of the research object and the automatic control of drilling. The azimuth adjustment range of the water drilling rig for the experiment is : ± 15°, and the pitch angle adjustment range is : + 5° to -10°.
