    • A weight-based tubular interlock apparatus adapted to determine whether a tubular is engagingly gripped by a rig-based hoisting device or a secondary gripping device is described. The apparatus includes at least two gripping mechanisms and an interlock system operatively connected that is adapted to measure a tubular load on at least one of the gripping mechanisms and to compare the tubular load to a predetermined load to deter nine whether the at least one gripping mechanism is gripping the tubular. The gripping mechanism is adapted to release the tubular only when the tubular load meets the predetermined load, upon which a release force sufficient to release the tubular from the gripping mechanism is applied to the tubular relative to the gripping mechanism. Methods of using the interlock apparatus are also described.
    • 描述了一种重量为基础的管状互锁装置,其适于确定管是否由基于钻机的提升装置或辅助夹紧装置啮合地夹紧。 该装置包括至少两个抓握机构和可操作地连接的互锁系统,其适于测量至少一个夹持机构上的管状载荷,并将管状载荷与预定的载荷进行比较以阻止所述至少一个夹持机构 正在抓住管状物。 夹紧机构仅当管状负载满足预定负载时才释放管状物,在该预定负载上,相对于夹持机构将足以将管状件从夹紧机构释放的释放力施加到管状体上。 还描述了使用联锁装置的方法。
