为了推广人造金刚石钻探技术,我们对北京800型钻机做了改进:制造了与之配套的小口径高速转盘.使用结果表明,基本上满足了高速钻进的工艺要求.高速转盘的主要技术性能最大开孔直径φ91转盘通孔直径φ94转盘可变角度 70～90°增速器变挡级数 2转速(转/分)正转6级:955、650、358、283、192、105反转2级:264、77适应孔深 800～1000米结构这种高速转盘,是迁就北京800型钻机升降和给进系统而设计的.在小转盘一侧安装一增速器,使转盘捉高转速并增加挡数.传动系统如图1所示.它由底座、增速器和
In order to promote the synthetic diamond drilling technology, we have made improvements to the Beijing 800 drilling rig: we have built a small diameter high speed turntable with the results that basically meet the high speed drilling requirements. The main technical performance of high speed turntable Hole diameter φ91 turntable through hole diameter φ94 turntable variable angle 70 ~ 90 ° gearbox gear shift series 2 speed (r / min) Forward 6: 955,650,358,283,192,105 reverse 2 Level: 264,77 Hole depth 800 to 1000 meters Structure This high-speed turntable is designed to accommodate the lifting and feeding system of the Beijing 800-type drilling rig.A speed increaser is installed on the side of the turntable to make the turntable catch high speed Increase the number of gears. Transmission system shown in Figure 1. It consists of base, speed increaser and
