Development and application of TGQ-200RC multi-technique automatic drill

摘要:

新一轮找矿突破战略行动对钻探技术提出更高要求，利用浅钻技术在浅覆盖区进行快速查证是重要的技术手段。多工艺钻探可以为复杂地层钻探施工提供绿色高效的钻探技术支撑。围绕这一需求研制了TGQ-200RC型多工艺自动化钻机，制定了钻机的总体方案，研制了多工艺动力头、夹持拧卸装置、6自由度移摆管机构、车装集成式液压储杆库、电液控制及参数监测系统等钻机主要部件，规划了自动加减钻杆过程中多机构协同动作控制流程。实钻试验表明，TGQ-200RC型钻机钻进效率高，取样质量好，具有多工艺、机动化、自动化、数字化等特点，单次自动加减钻杆平均用时约90 s，配合无线遥控可实现孔口无人操作，有效降低劳动强度，提高施工安全性。TGQ-200RC型多工艺自动化钻机可以为构建绿色、高效、经济的快速查证钻探技术体系提供坚实支撑，为推动国内浅层钻探装备自动化升级提供有益借鉴。

Abstract:

The new round of strategic action for mineral exploration breakthrough has put forward higher requirements for drilling technology， and the shallow drilling technology is of great important for rapid verification in shallow cover area. Moreover， the multi-technique drilling technology can provide technical supports for green and efficient drilling in complex formations. Based on this requirement， the TGQ-200RC multi-technique automatic drill is developed. The overall schedule of the drill is formulated， and the main components of the drill are designed such as the multi-techniques power head， clamping and unscrewing device， 6-DOF drill rod swinging mechanism， vehicle-mounted integrated hydraulic rod storage， electro-hydraulic control and parameter monitoring system. Furthermore， the process of multi-mechanism collaborative action during automatic adding and removing drill rods was planned. The field test shows that the TGQ-200RC drilli has high drilling efficiency， good sampling quality， and features of multi-technique capability， mobility， automation， and digitization， the average time for a single automatic adding or removing of drill rods is about 90s. With the wireless remote control， it can achieve unmanned operation in the wellhead， effectively reducing labor intensity and improving operational safety. The TGQ-200RC multi-technique automatic drill can provide solid support for building a green， efficient and economical rapid verification drilling technology system， and useful reference for promoting the automated upgrading of domestic shallow drilling equipment.
