摘要
介绍了一种混联式新型TBM掘进机构试验台的实体建模、仿真分析、整机组装等概况;在TBM支撑-推进-换步控制中,根据机构运动的单环掘进、双环掘进、三环掘进和连续掘进等4种工况,模拟施工掘进作业,并将4种工况的机构运动时序动作进行细化,以更好地进行PLC的程序设计和编制;最后,在完成本试验台掘进机构的电液控制系统PLC硬件配置及选型后,根据掘进运动控制要求,采用程序初始化、手动控制、自动控制等三种程序控制模式,分别设计了试验台的加载器、支撑器、辅推进器、主推进器的PLC逻辑控制程序,试验结果表明,所设计的电液控制系统能准确控制推进机构的推进和换步动作,并能够实时反馈压力、位移和流量等模拟量的变化量,达到预期设计目标,相关理论数据为TBM的施工提供了参考。
This paper introduces the solid modeling, simulation analysis and the whole machine assembly of a new-type mixed TBM test-bed boring machine. In the control of TBM support-propulsion-change step, according to four working conditions of the mechanism motion, including single tunneling, double tunneling, triple tunneling and continuous tunneling, construction tunneling operation is simulated, and the movement timing sequence of the mechanism under four kinds of working conditions is refined to better design and compile PLC programming. After completing the hardware configuration and selection of the electro-hydraulic control system of the tunneling mechanism of the test bench, according to the requirements of the tunneling motion control, three program control modes, such as program initialization, manual control and automatic control, are used to design PLC logic control program of the loader, support, auxiliary propeller and main propeller of the test-bed respectively. The test results show that the designed electro-hydraulic control system can accurately control the propulsion and step-change action of the propulsion mechanism, and can feedback the variation of the analog quantity such as pressure, displacement and flow in real time to achieve the expected design goal.Relevant theoretical data provides reference for TBM construction.
