ABSTRACT:
A gripping apparatus for supporting a tubular includes a longitudinal opening extending therethrough. A bowl is formed on an inner wall of the housing to provide an incline surface for one or more gripping members. As the gripping members are move down along the incline, the incline causes the gripping members to move radially toward the tubular and contact the tubular. In one embodiment, the housing comprises two body portions coupled together using one or mores hinges. In one aspect, the bowl is formed as a recess in the inner wall of the housing. The hinges of the housing are progressively curved to accommodate the recess bowl, thereby increasing the tubular size handling capacity of the gripping apparatus. In another embodiment, the apparatus may include guide keys that mate with guide slots formed on an outer surface of the gripping members to minimize the rotational movement of the gripping members relative to the housing. In another embodiment, the apparatus may include a leveling ring connected to the one or more gripping members for synchronizing the movement of the one or more gripping members. In another embodiment still, the flange may include one or more blocks for mating with a rotary table. In another embodiment still, the apparatus may include one or more adjustable guide rollers to facilitate movement of the tubular within the housing.
