AI Technical Summary
Existing automated drilling rigs are inefficient and complex to operate in offline pile-mounting operations, and require high levels of operator proficiency and collaborative control capabilities, making it difficult to further improve operational efficiency and automation levels.
The system adopts a single offline mouse hole layout, combined with dual-powered catwalks, single and dual-powered drill rod boxes, a lifting pipe laying system, and a retractable iron drill, which simplifies drill rod delivery and connection operations. It achieves the connection of the standpipe through a one-time drill rod delivery and a one-time top-down operation, and reverses the unloading process of the standpipe, reducing tool switching and manual intervention.
It significantly improves drilling efficiency, shortens operation cycles, enhances the level of automation and reliability of operations, adapts to different operation scenarios, and reduces operational difficulty and failure rate.
