内容简介：

I 摘 要 潜孔钻机是一种典型的工程机械，液压系统缓冲技术是影响回转运动平稳性的重要因素，既要满足回转机构的快速回转运动以获得较高的作业效率，又要保证回转运动的平稳停止和精确定位性能，就必须有效的优化 动力头 液压回转系统的 工作原理 。 本文首先分析了工程机械和潜孔钻机的发展趋势及市场需求，以及潜孔钻机的 动力头 液压回转机理，回转作业下对潜孔回转机构 工作原理 的要求，分析了潜孔钻机 动力头 液压回转系统的 工作原理 是影响钻孔回转机构 工作原理 的关键因素，在工程机械中具有典型性，国内外工程机械企业都十分重视回转运动平稳性及精确定 位性能的研究与应用，提出了解决现有技术问题的意义，以及进行本课题研究的必要性。 本文是本人在湖南山河智能股份有限公司的生产实习与理论相结合的前提下，分析了潜孔钻机 动力头 液压回转系统的 工作原理 ，建立了潜孔钻机 动力头 液压回转系统的 工作原理图 ，研究分析了潜孔钻机 动力头 回转机构 各种执行元件 对机构回转的 工作原理 的影响，通过对 动力头回转液压系统的回路压力 损失 和 液压系统的发热温升 的验算 ，获得了具有设计指导意义的数据， 取得了较显著的效果。 通过本次的设计，使我了解并得到了潜孔钻机 动力头 液压回转系统的 工作原理分析的理论依据 ，掌握了合理应用基础的液压元件对液压系统进行优化匹配的科学方法，同时为以后的潜孔钻机设计提供了可参考的理论依据，希望可以提升国产工程机械产品的技术性能及整体的技术水平，为中国潜孔钻机走向国际化打下了基础。 nts II Abstract Down-hole drilling rig is a representative construction machine, whose cushion technology of hydraulic system is the important factor of influencing the stability of rotary motion. The effective optimized dynamic characteristic of hydraulic rotary system not only can meet the high rotary speed of rotary mechanism to reach a higher work efficiency, also guarantee workelements of rotary motion . Firstly this thesis analysis the development and market demand of firstly this analysis the development and market demand of Construction machine and Down-hole drilling rig, Down-hole drilling rig and its hydraulic rotary theory， hen propose the work elements of hydraulic rotary system is a key factor of influencing work elements of rotary mechanism and representative in construction work elements of rotary mechanism and representative in construction machine field in view of the requirements the moving performance of rotary mechanism. In overseas or at home, the construction machinery enterprises attach importance to the study and application of the steady and pinpointing of rotary mechanism. For this reason, I address the signification of solving the present problem and the necessity of carrying out this study . This thesis based on the combination of production practice and theory study by author in Hunan Sunward Co. Ltd analysis the workelements of hydraulic rotary system, built Down-hole drilling rig of hydraulic rotary system and workprinciple study, Disquisition analysis the Down-hole drilling rig power hydraulic rotary system enforce element face to face rotary of workprinciple of infection.Through the of hydraulic rotary system test of loop drang loss and hydraulic rotary system fever rise checking computations.we get the significant data for design and instruction, achieving distinguished aims. Through this study, I get to know the dynamic the workelements and analysis theory basis of hydraulic rotary system of Down-hole drilling rig nts III and grasp the scientific methods of applying basic hydraulic component to optimize the hydraulic system.At the same time, this thesis offer theory basis for the future design of Down-hole drilling rig for the hope of advancing the total technic
