新型石油钻杆液压矫直机结构分析

Analysis and Design of Oil Drill Pipe Hydraulic Straightening Machine

目前的钻杆矫直装置存在矫直精度低和工作效率低的问题。设计了一种新型的石油钻杆液压矫直机。采用三点矫直原理对弯曲钻杆进行矫直,通过旋转机构旋转钻杆,并检测出弯曲位置。由移动式主机移动钻杆,使弯曲位置对准压头,提高了工作效率和矫直精度。应用有限元方法分析了关键部件的强度,满足使用要求。

Considering the disadvantages of the existing drill pipe hydraulic straightening machines which have low straightening accuracy and low efficiency,a new kind of drill pipe hydraulic straightening machine was designed,adopting three-point straightening principle to straighten curving drill pipe.Its rotating mechanism first rotates the curving drill pipe and detects the curving position,and then the movable machine moves the drill pipe to make the curving position aligned to the pressure head.The finite element method is used to check the key parts of strength,which satisfied the operating requirement.
