发明名称 Tubular handling apparatus
摘要 A tubular gripping assembly for use with a top drive to handle a tubular includes a tubular gripping tool having a mandrel and gripping elements operatively coupled to the mandrel; and a link assembly attached to the mandrel, wherein a load of the link assembly is transferred to the mandrel. The tubular gripping assembly may also include one or more of a swivel having selectively actuatable seals, a thread compensator to facilitate tubular make-up, or a wedge lock release apparatus to facilitate the release of gripping elements from the tubular.

主权项 1. A tubular handling assembly for use with a top drive, comprising: a mandrel coupled to the top drive; an actuator for moving gripping elements between a tubular gripping position and a tubular releasing position; a tubular engagement member for engaging a tubular; a clamping indicator coupled to the gripping elements for indicating a position of the gripping elements; and a coupling indicator coupled to the engagement member for indicating a position of the tubular, the coupling indicator including a longitudinally movable elongated member having spaced apart tapered portions and a sensor linked to the elongated member for transverse movement relative thereto in response to engagement with the tapered portions.
