摘要： A system (10) for drilling a subterranean borehole (20). In an embodiment, the system includes a mast (12), and a pipe rotator (50) coupled to the mast. The pipe rotator includes a stem (52) that is configured to be coupled to an end of a drillstring (30) and a motor (51) that is configured to rotate the stem. In addition, the system includes a guide beam (150) coupled to the mast. The guide beam includes a longitudinal axis and is configured to guide vertical motion of the pipe rotator. The guide beam includes a plurality of elongate sections (151, 152, 153) configured to be generally aligned along the longitudinal axis. In addition, the guide beam includes a plurality of coupling assemblies configured to interconnect the plurality of elongate sections and align the plurality elongate sections along the longitudinal axis.
