摘要： A gearbox for a roller in a spinner wrench is provided. In some embodiments, the gearbox can be disposed internally to the roller and can include a sun and planet type epicyclical gear-reduction assembly. In further embodiments, the gearbox can include a second sun and planet type epicyclical gear-reduction assembly to provide for a second, or final, stage reduction. Some embodiments can provide for reduction-ratios close to 3:1 and can be driven by a relatively small motor. The planet gears can be used to drive an annular gear which can spin the roller. In some embodiments, the gearbox can use high-capacity bearings.

摘要： 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.

摘要： A wrench for making up or breaking up a pipe joint is provided. The wrench comprises a tong assembly having an upper tong and a lower tong. The upper tong has a first upper tong half pivotably connected to a second upper tong half at their first ends. The lower tong has a first lower tong half pivotably connected to a second lower tong half at their first ends. A central bearing operatively couples the upper tong and the lower tong to allow the upper tong to rotate relative to the lower tong or vice versa. The tong assembly has a ram assembly for pushing or pulling the upper tong at a tangential location thereof and the ram assembly is retracted or extended to move the tong assembly between an open position, a closed position, and a rotated closed position where the upper tong is rotated relative to the lower tong.

摘要： 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.
摘要翻译：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。
