山东冶金地质勘探公司三队,遵照毛主席关于破除迷信,解放思想的教导,于1969年提出研究电钻的任务。在上级党组织和领导的关怀、支持下,大搞群众运动,坚持内外“三结合”,与上海电器研究所、沈阳电机厂等单位协作,经过三年来的紧张工作,终于试制出电钻样机,并进行了岩心钻探实验。结构及特性有杆电钻,是将地面动力移到地下直接驱动钻头的一种电动钻具。它的主要特点是动力机潛入孔内;钻杆不回转,与电机定子机壳相连,以克服反扭矩。
Shandong Metallurgical Geological Exploration Company three teams, in accordance with Chairman Mao on the eradication of superstition, emancipation of the mind, in 1969 put forward the task of studying electric drill. With the care and support of the party organizations and leaders at the higher level, the mass movement has been vigorously pursued and the “triple combination” of internal and external aspects has been adhered to. After three years of intense work, in collaboration with Shanghai Electric Research Institute, Shenyang Electric Machinery Factory and other units, And conducted a core drilling test. Structure and Features Rod electric drill, is an electric drill that moves the ground power directly to the ground to drive the drill bit. Its main feature is the power machine into the hole; drill rod does not rotate, connected with the motor stator casing to overcome the anti-torque.
