摘要
根据TK-3型液压立轴式岩心钻机结构分析产生液压卡盘失灵、主动钻杆卡死等故障的原因．提出了两套改造方案。通过车间空载试车及野外现场钻进验证，改进方案可行，完全符合煤炭地质钻探金刚石钻进、绳索取心技术工艺要求。
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.
