旋挖钻机作为一种基础工程中成孔作业的桩工机械,具有多功能、高效率等特点,在我国基础设施建设工程中得到广泛应用。结合旋挖钻机的特点,分析工作过程中各种不利工况极限状态,采用稳定角法对作业及行走工况下动态稳定性的分析计算进行研究,以便对整机重心进行合理布置,确保产品工作安全性。
Rotary drilling rig as a basic engineering into the hole operation pile machinery, with multi-function, high efficiency and other characteristics, in China’s infrastructure construction projects have been widely used. Combining with the characteristics of rotary drilling rig, this paper analyzes the limit state of various unfavorable working conditions during the working process, and uses the method of stable angle to analyze and calculate the dynamic stability under working and walking conditions so as to arrange the center of gravity of the whole machine rationally and ensure the products Work safety.
