Abstract

本实用新型提供的矿井下巷道支护用伸缩撑杆，包括中空套筒1、中空套筒2、紧固螺栓3和撑杆钩4，中空套筒1与中空套筒1嵌套链接，连接处设有紧固螺栓3，撑杆钩4固定于中空套筒1顶部。在采掘巷道对称两侧使用该装置后，可以很方便地将一根横梁支撑于巷道顶部，把钢丝网固定与高度不同的巷道顶板上。本实用新型结构简单，操作方便，可广泛应用于煤矿或其他矿产开采巷道支护中。

Description

矿井下巷道支护用伸缩撑杆
技术领域
本实用新型涉及一种矿井下巷道支护用伸缩撑杆。
背景技术
目前矿井下巷道支护要用W钢带将8#钢丝网通过膨胀螺栓固定与顶板上，且W钢带比较重，在W钢带孔内打眼固定时，要将W钢带暂时紧贴在顶板上，操作起来十分不方便。
实用新型内容
本实用新型提供的矿井下巷道支护用伸缩撑杆，在采掘巷道对称两侧使用该装置后，可以很方便地将一根横梁支撑于巷道顶部，把钢丝网固定与高度不同的巷道顶板上。
本实用新型提供的矿井下巷道支护用伸缩撑杆，包括中空套筒1、中空套筒2、紧固螺栓3和撑杆钩4，其特征在于：中空套筒1与中空套筒1嵌套链接，连接处设有紧固螺栓3，撑杆钩4固定于中空套筒1顶部。
本实用新型结构简单，操作方便，可广泛应用于煤矿或其他矿产开采巷道支护中。
附图说明
