摘要
为改进常规手动控制、反四连杆结构放顶煤过渡液压支架,研制一种自动化控制、高效又能安全支护的电液控制正四连杆放顶煤过渡液压支架。介绍了该液压支架的设计方案、技术参数、主要结构、使用中的优势、液压及电液控制系统等。为智慧矿山开采的发展提供一种更具优势的选型方案。
To improved the conventional structure of manual control and reverse four-bar linkage for transition hydraulic support of caving, developed a kind of electro-hydraulic control normal four-bar linkage caving transition hydraulic support with automatic control, high-efficiency and safe support.Introduced the design scheme, technical parameters, main structure, using advantages, hydraulic system and electro-hydraulic control system of the hydraulic support. It provides a more advantageous selection scheme for the development of intelligent mining.
