    • A spinner wrench for use on a drilling rig is provided. In some embodiments, the wrench can comprise three or more spinning rollers that can be disposed around a tubular. The three or more rollers can be connected to three or more hydraulic rams. In some embodiments, each ram can be connected to a single roller and the axis of the ram can be in a plane perpendicular to the pipe axis but not intersecting the pipe axis. For improved performance during make-up, in planar view, each ram axis can be offset to a counterclockwise direction around the drill pipe axis. For improved performance during break-out, in planar view, each ram axis can be offset to the clockwise direction. In some embodiments, the three or more rollers can be disposed around the drilling pipe or other tubular by a main body and one or more latching bodies.
    • 提供了一种用于钻机的旋转扳手。 在一些实施例中,扳手可以包括可以围绕管状物设置的三个或更多个纺丝辊。 三个或更多个辊可以连接到三个或更多个液压柱塞。 在一些实施例中,每个压头可以连接到单个辊,并且压头的轴线可以在垂直于管轴线的平面中,但不与管轴线相交。 为了在化妆时提高性能,在平面视图中,每个柱塞轴线可以偏置到围绕钻杆轴线的逆时针方向。 为了在突破期间提高性能,在平面视图中,每个柱塞轴可以偏移到顺时针方向。 在一些实施例中,三个或更多个辊可以通过主体和一个或多个闩锁体设置在钻孔管或其它管状物周围。

    • A floor wrench for a drilling rig floor is provided. The wrench can include a tong assembly having upper and lower tongs made up of articulated tong blocks that can move and lock together to enclose and make or break a joint between sections of drilling pipe. Each tong block can include a pair of die ram assemblies wherein each tong can have dies to grip the drilling pipe around its circumference. The tong assembly can be mounted in a frame configured for horizontal and vertical movement to and from the pipe joint. In some embodiments, the wrench can further include a pipe spinner having motorized spinners that can spin the upper pipe to form the joint prior to torqueing the joint together, or for uncoupling the upper pipe after the joint is broken.
    • 提供了一个用于钻机地板的地板扳手。 扳手可以包括钳组件,其具有由铰接的钳块组成的上钳和下钳,所述钳和钳可以移动并锁定在一起以封闭和制造或打破钻管的部分之间的接头。 每个钳块可以包括一对模具冲头组件,其中每个夹具可以具有模具以围绕其圆周夹持钻管。 钳组件可以安装在框架中,用于水平和垂直移动到管接头和从管接头移动。 在一些实施例中,扳手还可以包括具有电动旋转器的管旋转器,其可以在将接头扭转到一起之前旋转上管以形成接头,或者在接头断裂之后解开上管。
