Therefore, in this paper, a new type of pipe grabbing mechanical arm for well dressing machine is designed, the motion simulation of the mechanical arm under different working conditions is carried out, and the mechanism parameters or structure of the mechanical arm are optimized to realize the high efficiency and accuracy of lifting and lowering the pipe column.	cache/ajst-30187.pdf	txt/ajst-30187.txt
