伞形钻架一般悬吊在井架翻矸平台下面,即在垂直于翻矸方向上,安设一根工字钢梁,吊挂着伞形钻架的小滑车以工字钢梁作移运轨道,滑车行走可用人力或11.4千瓦内齿轮绞车通过滑轮组移位到主提升位置附近,伞形钻架由主提升钩头夺钩下井。伞形钻架的井下夺钩对中,一般用辅助提升钩头挂一根长30米的钢丝绳,从吊盘中心孔下放到伞形钻架挂钩位置,或在吊盘的主提升喇叭口至井筒中心专留一个钢丝绳移位的孔道,用人力将伞形钻架推至井筒中心进行定位。以上所述的伞形钻架安放、移位和夺钩
Umbrella-shaped drill frame is generally suspended in the derrick turn rock platform below, that is perpendicular to the turn in the direction of refuse, the installation of an I-beam, hanging umbrella tower drill a small pulley to I-beam for movement Tracks, trolleys can be used to move manpower or 11.4 kilowatts internal gear winch through the pulley group to move to the main lift near the location, the umbrella-shaped rig by the main lifting hook to grab the hook. Umbrella-shaped drill rack downhole hook, generally with the auxiliary lifting hook hanging a 30-meter-long wire rope, hanging down from the center hole to the umbrella-shaped drill rack hook position, or in the lifting of the main hoist to the bell Wellhead center dedicated to leave a hole in the wire rope displacement, the manpower to push the umbrella-shaped drill rig to the center of the wellbore positioning. The umbrella-shaped drill holder described above is mounted, displaced and grabbed
