摘要： The assembly is designed to convert a conventional land rig to "top drive". It comprises a torque track that is shipped in sections and is assembled to form a rigid track extending vertically in the derrick. The track is rigidly attached to the derrick only at its base, so that the track is free to twist and deflect laterally along its length. The housing of the top drive is connected by an angled, pivotally mounted link means with a tubular bushing that embraces and slides along the track. The link means and bushing are adapted to restrain rotation of the housing relative to the track, while transmitting both side and torque reactive loads to the track. The angled pivoting link enables the top drive to be displaced outwardly to a position over the mousehole. The top drive incorporates a hydraulic motor and gear drive assembly for rotating a drive shaft connecting the drill string and hoisting means. The housing does not carry the drill string load and can be made lighter and more compact as a result.
摘要翻译：该组件旨在将传统的陆地钻机转换为“顶级驱动”。它包括扭矩轨道，该扭矩轨道部分运输并组装成形成在井架中垂直延伸的刚性轨道。轨道仅在其底座处刚刚附接到井架，使轨道自由地沿其长度横向扭曲和偏转。顶部驱动器的壳体通过成角度的，可枢转地安装的连杆装置连接，管状衬套沿着轨道包围和滑动。连杆装置和衬套适于在将两侧和扭矩无功负载传递到轨道的同时，相对于轨道限制壳体的旋转。倾斜的枢转连杆使顶部驱动器向外移位到鼠标孔上方的位置。顶部驱动器包括用于旋转连接钻柱和提升装置的驱动轴的液压马达和齿轮驱动组件。壳体不承载钻柱负载，因此可以使其更轻更紧凑。
