摘要

旋挖钻机主卷扬既可以安装在回转平台上,也可以安装在钻桅下部。为研究主卷扬在旋挖钻机中的布置对钻桅变幅油缸载荷性能的影响,基于钻桅变幅机构各刚体的受力及其围绕钻桅和三角架之间铰点的力矩平衡分别建立主卷扬位于回转平台上和钻桅下部时钻桅变幅油缸载荷的数学模型,在Simulink仿真平台上构建基于Matlab函数的仿真模型并进行仿真分析。结果表明:主卷扬安装在回转平台上时钻桅变幅油缸载荷稍微大于主卷扬安装在钻桅下部时钻桅变幅油缸载荷,且前者会受到动臂变幅的影响,不过其载荷的稳定性较好。最后,该载荷的仿真结果得到了实验验证。

Abstract

The main winch of rotary drilling rig is mounted on the platform or the lower part of the drilling mast. Effects of mount position of the main winch on the drilling mast hydraulic cylinder load are discussed in the present article. Based on forces on the body of the drilling mast luffing mechanism,and the torque equilibrium around the hinge between the drilling mast and the triangle,a mathematic model of the drilling mast hydraulic cylinder load was established when the main winch was mounted on the platform,and another mathematic model of the drilling mast hydraulic cylinder load with the main winch mounted on the lower part of the drilling mast was also developed by simplifying the mathematic model with the main winch mounted on the platform. A simulation model was built up and analyzed in Matlab software. The results show that the drilling mast hydraulic cylinder load with the main winch mounted on the platform is relatively larger than that on the lower part of the drilling mast,the former is influenced by the lift-arm angle,and compared with the latter,the former exhibits relatively good stability. At last,the simulated results with the main winch mounted on the platform are testified by the experimental data.
