摘要: 为解决目前双三角钻臂液压系统参数设计采用相关经验值加安全系数的方法存在的系统压力设计偏高、液压部件选配耐压等级大、系统发热严重、制造维保成本高、系统功耗大等问题,对双三角钻臂结构进行理论分析,采用运动轨迹投影和静力学分析的方法,建立钻臂运动过程中双三角负载与运动位置之间的关系,根据臂架设计参数获取其极值及其极值位置的油缸负载参数。根据双三角结构工作原理并结合臂架工作环境,设计一种负载敏感液压控制系统,经理论分析和计算,确定系统的原理和液压元件的主要参数并试验。试验结果表明,运动极值位置的液压系统负载参数与理论分析参数基本一致,系统运行整体平稳可靠,随动油缸调节功能正常,隧道内试验3 h液压系统温升65.5 ℃,证明该液压系统设计的合理性和可应用性。

Abstract: When using the relevant empirical value and safety factor to design the hydraulic system parameters of doubletriangular drill boom, problems such as high system pressure, large pressure resistance level of hydraulic components, serious system heating, high manufacturing and maintenance cost, and high power consumption exist. To address these problems, the structure of the doubletriangular drill arm is theoretically analyzed, the extreme position of the doubletriangular load in the process of the drill arm movement is calculated using the methods of motion trajectory projection and static analysis, and the oil cylinder load parameters at the extreme position are obtained. Then, a load sensitive hydraulic system is designed based on the working principle of doubletriangle structure and the working environment of boom. The principle of the system and the main parameters of hydraulic components are determined through theoretical analysis and calculation. The test results show that the load parameters of the hydraulic system at the extreme position of motion are basically consistent with the theoretical analysis parameters, the overall operation of the system is stable and reliable, and the adjustment function of the servo cylinder is normal. The temperature rise of the hydraulic system in the tunnel for 3 hours is 65.5 , which validates the rationality and applicability of the design of the hydraulic system.
