摘　　要：盾构是一种专用于地下隧道开挖的技术密集型重大工程装备,管片拼装机是盾构的重要组成部分,它主要负责将管片安装到刚开挖好的隧道表面,形成衬砌,使隧道一次成型。要实现对管片拼装的准确定位,就必须采用电液比例控制技术。对实现管片拼装的6个自由度运动及一个抓持运动的液压控制系统进行了详细分析,包括管片拼装机纵向、径向及周向液压控制系统以及姿态液压控制系统和抓持液压控制系统,同时对液压控制系统的关键元器件液压泵和电液比例多路阀的选型进行了分析。现场管片拼装测试表明该液压控制系统是合理可靠的,能完成管片的拼装工作。同时该液压控制系统设计时综合考虑了整个管片拼装的运动过程,不但能实现完全自动控制,而且能准确定位,可为不同类型盾构管片拼装的液压驱动控制提供参考。Shield is a kind of technology-concentrated heavy construction equipment dedicated for underground tunnel boring.Pipe piece installing machine is the important composition of a shield.It is responsible for installing pipe pieces onto the tunnel surface just bored to form a lining.In this way,a tunnel can be shaped by one path of TBM.In order to realize accurate positioning in pipe installation,electro-hydraulic proportional control technology has to be applied.A hydraulic control system that realizes 6 degree of freedom movements of the pipe piece and one holding movement is expatiated,which includes hydraulic control systems of the pipe piece installation machine in longitudinal,radial and circumferential directions,hydraulic control system for posture and hydraulic control system for holding.At the same time,model selection for key hydraulic parts,such as hydraulic pump and electro-hydraulic proportional valves,is analyzed.Field pipe installation test shows that the hydraulic control systems are rational and reliable and can fulfill the pipe installation project.Besides,the complete pipe installing is totally treated as a moving procedure in the design of hydraulic control systems so that not only is completely automatic control realized but also accurate positioning.All these provide reference for hydraulic drive control of different kind of shield pipe piece installation.
