Description

硬岩钻杆
技术领域
本实用新型涉及一种硬岩钻杆,与风动凿岩钻机配套使用进行硬岩打孔。
背景技术
以前的硬岩钻杆采用螺纹与风动凿岩钻机连接,装拆麻烦,传动的扭矩小,连接不牢固,抗冲击能力差。
发明内容
本实用新型的目的是提供一种硬岩钻杆,解决原有钻杆装拆麻烦、传动扭矩小、连接不牢固、抗冲击能力差的缺陷。
本实用新型的目的是以如下方式实现的:钻杆体的中心有水孔,钻杆体的前端为外锥柄,钻杆体的后部外周上有圆箍,钻杆体处于圆箍后部的部分为截面为六方的钻柄。使用时,六方钻柄与风动凿岩钻机连接,圆箍轴向限位。
钻杆体处于圆箍前部的外周截面为六棱形,便于排屑。
本实用新型与钻机连接牢固,装拆方便,传动扭矩的能力强,抗冲击能力大,钻进方便。
附图说明
附图是本实用新型的结构示意图。
具体实施方式
参照附图,钻杆体2的中心有水孔3,钻杆体2的前端为外锥柄1,钻杆体2的后部外周上有圆箍4,钻杆体2处于圆箍4后部的部分为截面为六方的钻柄5,钻杆体2处于圆箍4前部的外周截面为六棱形。

Claims (2)
