| Abstract: | Analyzed causation of TK-3 hydraulic vertical shaft coring drilling rig easy to bring hydraulic chuck failure, get stuck with actuating rod ere, put forward two alteration schemes. Through workshop idling test-drives and field drilling validation confirmed the schemes, fully satisfying coal geological diamond drilling, and wire-line coring drilling technological requirements. |
