摘要

钻机在矿床普查勘探中,特别是有色金属稀有金属等矿床普查勘探中,坑道

钻探用于追索矿床,加密勘探勘察地质构造圈定矿体及取样和验证等；钻机在矿山开凿中，常用坑道钻探技术来钻凿地下观测孔、通风孔、排水孔、瓦斯排放孔、注浆孔、爆破孔、锚定孔及开凿坑道的先导孔等；钻机在其他岩土工程施工领域中,坑道钻探的装备和工艺技术可用于坝基的边坡加固地质灾害的治理深基坑的支护,以及工业商业交通军事等方面的地下工程施工。

本文通过介绍顶驱钻机，根据机械振动理论,得出系统的运动微分方程,并针对研制的实际情况,合理的确定了顶驱系统的振幅、激振频率、激振力、偏心力矩等主要参数。根据顶驱的振动过程,进行动力学分析,在此基础上建立虚拟样机,得到了箱体质心位置、偏心块质心位置以及激振力等随时间变化的参数曲线,实现了对顶驱系统虚拟样机的动力学仿真分析。应用ANSYS软件对顶驱系统主要承力构件冲锤进行有限元分析,用此分析顶驱系统的设计是否满足使用要求,为研究生产样机提供了理论依据。同时,钻机进行了空运转实验和生产性实验用以验证顶驱结构设计合理。

Abstract

Census exploration drilling of the deposit, especially non-ferrous and rare metals deposits census exploration, drilling tunnels for recourse deposits, geological survey and delineation of encryption ore exploration and sampling and verification; rig drilled in the mine, the common tunnel drilling Ground observation technology to drilling holes, ventilation holes, drain holes, gas discharge hole, grouting holes, blasting holes drilled anchor holes and trenches of the pilot hole, etc drill in other areas of geotechnical engineering, tunnel drilling equipment And technology can be used for the dam foundation Slope control of geological disasters in the deep foundation of support, as well as industrial and commercial transport and military aspects of underground construction.

By introducing the top drive drilling rigs, according to mechanical vibration theory, the obtained differential equations of motion, and for the development of the actual situation, the reasonable determination of the top drive system, the amplitude, excitation frequency, the exciting force, eccentric torque, and other major parameters。According to the vibration of the top drive the process of dynamic analysis, based on this prototype, get a box center of mass position, eccentric, and exciting force centroid position changes with time parameter curves on the top drive system to achieve a virtual Prototype dynamic simulation analysis。Application of ANSYS software to the top drive system, load-bearing component hammer finite element analysis, using this analysis whether the top drive system design to meet the requirements for the study of the production prototype provides a theoretical basis. Meanwhile, the rig air operation conducted experiments to test and verify the production of top drive structure design.

Keywords: drilling rig; top drive design; virtual prototype; dynamic simulation analysis
