Research of precise pushing control scheme for hydraulic support and its application
摘要
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.关键词
