摘要
为促进煤矿钻头打捞工作的顺利进行,基于常见打捞方法存在的主要技术缺陷,分析一种卡夹式打捞钻头,具体介绍了该钻头的结构及工作原理,并提出了具体的卡夹式打捞工艺流程,总结了卡夹式打捞钻头卡紧钻杆的条件,以供打捞工作参考。
In order to promote the smooth progress of the salvage work of coal mine bit,based on the main technical defects of common salvage methods,a clip-type salvage bit is designed,the structure and working principle of the bit are introduced in detail,clip-type salvage process flow is put forward.The paper summarizes the conditions of clamping drill bit for fishing work.
