In the field of construction machinery, the drill rod of rotary drilling rig has always faced many difficulties in handling due to its own characteristics, which urgently need to be solved.

The situation of drill rods for rotary drilling rigs is quite complex, with varying lengths. Some drill rods can be as long as 25m or even longer, and there are multiple key bars distributed on the drill rods. In the automatic production process, the drill rod needs to go through multiple stages such as the positioning machine and the welding station of the robotic arm, which means that the drill rod needs to be circulated between different stations, and the requirements for handling are quite high.
