AI Technical Summary
The boom system of the existing rock drilling rig has an uneven downward angle due to the dual pitch cylinder structure, which leads to interference problems. In addition, the dual reducer structure has strong degree of freedom coupling, complicated operation, and low hole position switching efficiency.
The system employs a seven-degree-of-freedom boom system, including a mounting base, outer boom, pitch rotation assembly, yaw rotation assembly, inner boom, yaw leveling assembly, pitch leveling assembly, slewing assembly, and propulsion beam base. Each kinematic pair can operate independently, achieving pitch, yaw, and slewing movements through independent control, thus reducing coupling.
It achieves high flexibility of boom, large construction range, precise positioning, convenient hole switching, and simple operation, thus improving construction efficiency and safety.
