摘要
以突出松软煤层钻机的螺旋钻杆为研究对象,重点介绍了螺旋钻杆两个重要参数——叶片的螺旋升角和螺距的设计过程,简要地说明了螺旋钻杆在 ZY-1250型矿用全液压坑道钻机上的应用情况,验证了螺旋钻杆参数设计的正确性。
Taking the drill anger stem in outburst loose coal seam as studying object, the design process of key parameters including the lead angle and thread pitch of blades is expounded. The application of the auger stem in ZY-1250-type mining full hydraulic tunnel drill is introduced, which shows the correctness of the auger stem parameter design.
