瓦斯钻机前动力头(夹持器)两用装置
Dual Purpose Device of Former Power Head (Gripper) for Gas Rig
摘要
Abstract
The conventional downhole gas drill needs to start and stop frequently in the drilling process to connect the drill pipe, this kind of frequent start and stop will cause the coal hole wall not easy to form, damage and loss of drill pipe and other situations. In view of this situation, a new front power head (gripper) device without stopping and continuous connection of drill pipe is proposed to solve the above problems. Based on the detailed introduction of the device, the mechanical performance of the whole mechanism is analyzed by means of ANSYS, and the fatigue life of the drill pipe clamp column is discussed. The results show that the overall static strength of the mechanism meets the requirements.关键词
