摘要: 针对液压支架液压系统存在控制精度差、支架推移步距不一致等问题，提出了一种液压支架精确推移控制方案。该方案通过引入推移控制逻辑阀，并优化电液控制系统自动推移控制流程，实现移架、推溜动作精确控制及销轴间隙自动消除功能。实验及现场应用结果表明，该方案提高了综采工作面液压支架自动推移控制精度，保证了支架推移步距的统一。Abstract: For problems of poor control precision of hydraulic system of hydraulic support and inconsistent step distance of support pushing, a precise pushing control scheme for hydraulic support was put forward. Precise control of support moving and scraper conveyor pushing and automatic elimination of pin roll gap are realized by introducing pushing control logical valve and optimizing automatic support pushing control flow of electro-hydraulic control system. The experimental and field application results show that the scheme improves automatic pushing control accuracy of hydraulic support on fully mechanized coal mining face and guarantees consistent step distance of support pushing.
