Abstract

本实用新型公开了一种螺旋密封垫,主要包括本体,其中,本体外侧设有矩形螺纹,内侧设有内通孔,本体为橡胶环。本实用新型设置在锚索钻杆连接套内,内侧设置的内通孔可使压力水流通过,同时防止水流从连接套处外流,提高了钻眼时钻杆末端水的压力,从而提高了钻眼效率,本实用新型具有结构简单、安装使用方便的优点。

Description

一种螺旋密封垫
技术领域
本实用新型涉及一种煤矿井下锚索钻杆连接套配件,尤其涉及一种螺旋密封垫。
背景技术
煤矿井下支护用钻眼,普遍采用锚杆机和配套锚索钻杆湿式钻眼,因钻眼较深锚索钻杆需用连接套连接较多钻杆,连接套与钻杆是矩形螺纹连接,间隙较大,密封不严,连接处漏水比较常见,导致钻眼时末端水压较小,钻眼时产生的岩石或煤不能及时被水排出,导致钻杆被夹和被堵,不能拔出,钻眼效率较低。
实用新型内容                                             
有鉴于此,本实用新型提供了一种可防止连接套处连接漏水,提高钻眼时钻杆末端水流压力,提高钻眼效率的螺旋密封垫。
本实用新型所采用的技术方案是:
一种螺旋密封垫,主要包括本体,其中,本体外侧设有矩形螺纹,内侧设有内通孔。
本体为橡胶环。
本实用新型技术方案的积极效果是:
本实用新型设置在锚索钻杆连接套内,连接每根钻杆可起到密封作用,防止连接套处连接漏水,内侧设置的内通孔提高了钻眼时钻杆末端水的压力,从而提高了钻眼效率,并且具有结构简单、安装使用方便的优点。
附图说明
下面结合附图对本实用新型进一步说明。
图1是本实用新型的结构示意图。
具体实施方式
由图1可以看出,本螺旋密封垫,主要包括本体1,其中,本体1外侧设有矩形螺纹2,内侧设有内通孔3。
由图1还可以看出,本体1为橡胶环。
