AI Technical Summary
Technical Problem
Existing drilling equipment cannot effectively drill peripheral holes at the edge of the rock surface, which limits the drilling range of the drill rod.
Method used
A peripheral hole drilling device is adopted, which connects the drill rig and the drill rod by staggered placement. The drill rod is driven by belt transmission and combined with the propulsion beam and cylinder system to ensure that the drill rod can drill close to the edge position. After drilling, the splitting rod is flipped and split directly.
Benefits of technology
This technology enables the drill rod to reliably reach the perimeter of the rock surface, reducing working time, improving drilling efficiency and stability, and reducing the limitations imposed by equipment size on drilling.
