摘要:

介绍了“地壳一号”万米钻机新型铁钻工伸展机构的组成以及工作原理，对所采用的平行四边形机构的速度进行了理论计算，应用ADAMS软件对伸展机构进行了动力学仿真分析，通过对伸展油缸施加不同的载荷和驱动方式，考察伸展机构动力学过程。研究结果表明伸展机构结构设计合理、工作平稳可靠。

Abstract:

The paper introduced the composition and working principle of new stretching mechanism of iron roughneck for “crust Ⅰ” myriameter drilling rig, made theoretical calculation on the velocity of the parallelogram mechanism used and conducted dynamic simulation analysis by ADAMS software. With different load and drive modes on the stretching cylinders, the dynamics process of stretching mechanism was investigated. The results indicate that the design of stretching mechanism is reasonable, smooth and reliable.
