摘要
目前,循环前移单元式超前液压支架在超前支护、滞后支护、上下隅角支护等方面使用越来越广泛。归纳了现有单元式超前液压支架常用的4种底座结构形式,介绍了各自的功能、结构特点和使用工况,阐述了2种新型单元支架底座结构形式,为单元支架结构选型提供了参考依据。
At present,the cyclic forward moving unit type advanced hydraulic support is increasingly used in advanced support,lagging support,upper and lower corner support,and other aspects.The four commonly used base structures of existing unit type advanced hydraulic supports were summarized,introduced their respective functions,structural characteristics,and usage conditions,and elaborated on two new types of unit support base structures,which provides reference basis for the selection of unit support structures.
