[0002] Long borehole drilling in coal mines is a fundamental measure and means to prevent and control coal mine gas disasters, mine water disasters, tunnel geological abnormal disasters and other mine accidents. During the drilling construction process, it is necessary to use a drilling rig to drive the drill rod into the coal seam or rock layer, and then recover the drill rod. With the construction of intelligent mines, automated and intelligent tunnel drilling rigs are becoming more and more popular. Automated drilling rigs are equipped with manipulators for loading / unloading drill rods and drill rod boxes, which can construct about 100 drill rods at a time, greatly reducing labor intensity and improving the safety of drilling construction. However, due to the limitations of tunnel space, the overall layout of the drilling rig is compact, and the capacity of the drill rod box is limited, which cannot meet the one-time long-distance drilling needs. The replacement of the drill rod box seriously restricts the further improvement of the working efficiency of the drilling rig. In addition, personnel are required to replace the drill rod box, which is labor-intensive and difficult. In addition, once an emergency occurs, it is often difficult for operators to dodge, which poses a great safety hazard to construction personnel. Summary of the invention
