在水文钻孔施工巾往往要多次拧卸各种套管,不仅工序频繁,而且钻工体力劳动强度大,配属时间长,影响施工进度.在广大钻探工人的迫切要求下,我们试制了两用套管卡帽,可以在北京500—1型钻机上使用,也可在北京800—1型钻机上使用.试用效果很好,很受钻探工人欢迎.如图所示:套管卡帽1坐在转盛心管上,使与心管的凸台接合,用齿瓦2把套管3卡牢,加长扭柱4,用钳子5咬住套管接头,开动转盘,即可实现机械扭卸套管.在卡帽下头,用螺丝固定
In the hydrological drilling construction towel often have to unscrew a variety of casing, not only the process is frequent, but also the manual labor strength, associated long time, affect the construction progress.In the urgent request of the majority of drilling workers, we trial two With casing cap, can be used in Beijing 500-1 drilling rig, also can be used in Beijing 800-1 drilling rig.Probing effect is very good, very popular with drilling workers.As shown: casing cap 1 Sit and turn Sheng heart tube, so that with the heart tube boss engagement, with the tile 2 casing 3 stuck, lengthening the torsion column 4, with a pliers 5 bite sleeve connector, start the turntable, you can achieve the mechanical torsion Remove the tube. Fix it with a screw under the cap
