摘　　要：针对孙家岔龙华煤矿人工开槽作业效率低、施工进度慢等问题,采用传动匹配、液压系统匹配、软件设计、理论公式计算等方法,对矿用巷道开槽机结构参数进行全面系统的研究设计。研究结果表明:开槽机胶轮行走结构更易布置,行驶速度快;通过软件建模、理论计算,设计确定了驱动桥长度、最大输入扭矩及轮胎直径宽度等参数;开槽机工作装置工作臂左右旋转角度设计为25°,并选取了满足安全使用要求的转向、举升及调节油缸;提出KC-8防爆柴油开槽机液压系统设计要求,需要匹配油缸和马达;确定主回路结构形式,液压泵首选额定压力稍大于系统工作压力的变量液压泵,解决了煤矿机械在巷道内行走和作业的难题,提高了生产效率。Aiming at the problems of low operation efficiency,slow construction progress and others of manual slotting in Sunjiacha Longhua Coal Mine,a comprehensive and systematic study and design of the structural parameters of the mine used roadway slotting machine are conducted using methods such as transmission matching,hydraulic system matching,software design,theoretical formula calculation and so on.The research results indicate that the rubber wheel walking structure of the slotting machine is easier to arrange and has a faster driving speed;Through software modeling and theoretical calculation,parameters such as drive axle length,maximum input torque,and tire diameter width,etc,are designed and determined;The working arm of the slotting machine's working device is designed to rotate left and right at an angle of 25°,and steering,lifting,and adjusting oil cylinders that meet safety using requirements are selected;Propose the design requirements for the hydraulic system of KC-8 explosion proof diesel slotting machine,which requires matching the oil cylinder and motor;By determining the structural form of the main circuit,variable hydraulic pumps with a rated pressure slightly higher than the system working pressure are preferred,which solves the difficult problem of coal mine machinery walking and operating in roadways and improves production efficiency.
