【摘要】：针对巷道临时支护支架的推移油缸在工作面工作过程中承受的偏载,设计了负载敏感系统与同步阀相结合的液压同步系统,使得推移油缸在承受偏载下也能达到较高的位移同步精度;使用AMESim仿真软件对该液压同步系统进行了建模和仿真分析,得到推移油缸的位移同步精度为0.68%;搭建了推移油缸液压同步系统的试验台,在推移油缸承受偏载下对液压同步系统进行了试验研究和分析,得到该系统推移油缸位移同步精度为1.32%,满足1.5%以内的设计目标。研究结果表明:负载敏感系统结合同步阀能在油缸承受偏载时抑制压力和流量的波动,保证流量不变,使得油缸同步运行,同时具有调速方便和节能的优点。
[Abstract]:Aiming at the partial load of the bed oil cylinder in the working face of the temporary support support in the roadway, a hydraulic synchronous system combining the load sensitive system and the synchronous valve is designed. The displacement synchronization accuracy of the bed load cylinder is also high under the bias load, and the hydraulic synchronous system is modeled and simulated by using the AMESim simulation software. The displacement synchronization accuracy of the bed load cylinder is 0.68. The test bench of the displacement synchronization system is built, and the hydraulic synchronization system is tested and analyzed under the load of the bed oil cylinder. The displacement synchronization accuracy of the system is 1.32, which meets the design goal of less than 1.5%. The research results show that the load sensitive system combined with the synchronous valve can suppress the fluctuation of pressure and flow rate when the cylinder is subjected to bias load, and ensure that the flow rate remains unchanged. The oil cylinder runs synchronously and has the advantages of convenient speed regulation and energy saving.
