摘　　要：设计了一种煤矿坑道瓦斯抽采钻机的变幅机构,介绍了其结构组成和工作原理,建立了其力学模型,推导出油缸的受力表达式。使用MATLAB软件描述了2组油缸的受力状态,并对安装稳固装置后变幅机构的受力情况进行了分析,为设计提供了理论依据。This paper designed the luffing mechanism in the coal tunnel gas drainage rig, introduced its structure and working principle, established its mechanics model, and derived the force expressions of oil cylinder. Base on the MATLAB software the force state of the two sets of the oil cylinder was described. The force state of the luffing mechanism was analyzed after installed the steady device. Those achievements provide a kind of theoretical basis for the design.
