1985年8月我队试制成功一台由圆柱齿轮减速器传动的全封闭单卷筒，可以自控、遥控运行的电动工作台，随即在铁东勘探区412号钻机投入试用，先后历经85—257；85—258；86—263等钻孔8个多月时间的施工应用，证明这种电动工作台的机械效率较高（和使用蜗轮蜗杆减速器时相比），而且具有工作可靠、使用安全、操作简单、维护方便、灵活耐用的优点，完全 In August 1985, our team successfully produced a fully enclosed single reel driven by a spur gear reducer, and an electric worktable that could be controlled by itself and remotely operated. It was then put into trial operation at No. 412 drilling rig in Tiedong Exploration District and successively experienced 85-257. 85-258;86-263 and other drilling applications for more than 8 months proved that this kind of electric workbench has higher mechanical efficiency (compared with the use of worm gear reducer), and it has reliable work and safe use. , Simple operation, easy maintenance, flexible and durable advantages, completely
