摘要:: 为了满足二次衬砌逐层逐窗布料的控制需求，设计一套液压自动控制系统。该系统采用双联液压泵，分别对回转驱动液压马达和浇筑对接口油缸进行不同压力的供油。对比3种回转圆周点位控制方法的优缺点，最终选择增量式旋转编码器对回转布料管圆周位置进行反馈。该系统的建立，实现了隧道二次衬砌的自动逐层逐窗浇筑，减少了工人劳动强度，提高了工作效率和浇筑质量。

Abstract:: According to the actions and control requirements of automatic concrete distributors of secondary lining,a set of hydraulic automatic control system was designed.Double hydraulic pump system was adopted to fuel supply to the rotary driver and hydro-cylinder pair interface of connecting casting with different pressures.The positions of the distributing pipes were fed by the encoder.The advantages and disadvantages of three kinds of control methods were compared,the incremental rotary encoder was finally selected to feedback the position of the rotary distributing pipe.The establishment of this system realized the casting of window-by-window and layer-by-layer of tunnel secondary linings,and reduced labor intensity of workers,and improved working efficiency and casting quality.
