摘要
分析了端头支架几种侧护帮装置的弊端,介绍了一种新型侧护帮装置及其工作原理;该侧护帮装置的应用,使端头支架在不拆除任何部件的前提下,能在巷道宽度变化较大的顺槽内顺利推进,且侧护帮板支顶、护帮效果好,增强了端头支架的适应能力。
The working principles and structure of new installation of protection wall from lean side are introduced. Has analyzed some kinds of end support installation of protection wall disadvantages. The new installation applied, no taking off unit of support, end support moves forward smoothly in width change greater transportation tunnel. It leans to protect wall and to support tunnel roof, strengthen end support adaptability.
