With the rapid development of China 's economy , cities , railways, highways and other infrastructure supporting efforts also continued to increase , while the fast and efficient construction equipment to become a strong guarantee . Needs of the construction , both the regulatory requirements for construction and construction of rotary drilling rig recognition , prompting the rotary drilling rig market is showing good prospects . This will not only promote the development of our foundation construction machinery , advanced infrastructure . Paper Rotary drilling rig power plant development at home and abroad , the structure and the basis of the composition , the use of three-dimensional engineering software to establish a model of the power plant , and its study of the following aspects : the analysis of rotary drilling rig power plant overview of the development of the working principles, characteristics , as well as at home and abroad , and at the same time introduce the the rotary bucket load status and characteristics of the short spiral drill drilling conditions . Analysis of the composition and structure of the rotary drilling rig power plant , as a platform to build a three-dimensional software SolidWorks four different forms of power plant model . The working principle and structure of the hydraulic control system of a typical power plant , hydraulic circuit design and simulation software control loop simulation, the optimum simulation results . Static and modal analysis of the key components of the power plant , and understanding of the various components of the stress and displacement distribution , and to meet the structural strength of the optimized design quality conditions to minimize the structural dimensions of the parts , and then as a driving force improvement and production of the device provides a theoretical basis and method .
