摘要
由于国内陆地钻机利用钻台气动绞车或吊车实现钻杆上下钻台时不稳定、效率低,本文设计了一套用于陆地钻机的钻杆自动起升系统,该系统可以实现钻杆在井场排放架和钻台之间自动传送,极大地缩短了钻井周期,提高了钻井效率。并利用ANSYS有限元软件对该系统的关键部件进行了有限元分析和结构优化,优化后的系统具有足够的强度、刚度和稳定性,满足长期使用的需要。
It is the instability and low efficiency that land rig lift drill rod up and down using pneumatic hoist rig or crane. This paper designs a set of automatic lifting system for land drill rod. The system can made drill rod automatic transmission between the drill pipe rack and the derrick floor, greatly shorten the drilling cycle and improve drilling efficiency. Some key parts structure of the system is analyzed and optimized in ANSYS software. So strength of optimized system, stiffness and stability are enough, and meet the requirements for long-term use.
