Abstract

本发明提供了一种锥式圆尖锚杆,有效地避免了以往钝式锚杆的弊端,该锚杆由紧固螺母、托盘、杆体、杆头组成,杆头采用圆锥式设计,锥尖成圆弧状,注入锚杆时,圆锥壁起到良好的导向作用,即使操作中有偏差,该锚杆也能顺利地注入,达到良好的锚固效果。

Description

一种锥式圆尖锚杆
技术领域
本发明属于巷道锚固、支护领域,具体的说是一种锥式圆尖锚杆。
背景技术
目前,广泛使用的锚杆顶部多为钝式设计,使用时,先在需要锚固或支护的地方打眼,然后将锚杆注入,钝式设计的锚杆在注入时,往往因为工人操作不当造成注入角度偏差,造成锚杆眼壁的戗起,给锚杆注入工作带来不便,重新注入往往造成外漏较长,达不到锚固或支护的效果。
发明内容
本发明提供了一种锥式圆尖锚杆,有效地避免了以往钝式锚杆的弊端。
本发明是这样实现的:该锚杆由紧固螺母、托盘、杆体、杆头组成,杆头采用圆锥式设计,锥尖成圆弧状。
本发明的有益效果是:杆头采用圆锥式设计,锥尖成圆弧状,注入锚杆时,圆锥壁起到良好的导向作用,即使操作中有偏差,该锚杆也能顺利地注入,达到良好的锚固效果。
附图说明
下面结合附图作进一步说明
图1是本发明的结构示意图
图中1、杆头2、杆体3、托盘4、紧固螺母
具体实施方式
将杆头加工成圆锥形,顶部打磨成圆弧状,使用时,将锚杆注入锚杆眼,杆头1的圆锥形设计有导向作用,操作中即使有偏差,杆头也不会将锚杆眼壁戗起,能够顺利地引导杆体2注入锚杆眼,达到锚固位置时,安装托盘3,旋紧紧固螺母4,完成锚固操作。
