摘要:
An apparatus (201; 301; 401; 501; 601) and a method to support a tubular member (291; 391A; 391B; 491; 691) are disclosed herein. The apparatus (201; 301; 401; 501; 601) comprises a bowl (203; 303; 403; 503; 603) having a longitudinal axis extending therethrough, in which the bowl (203; 303; 403; 503; 603) comprises a first opening (207) formed at a top side of the bowl (203; 303; 403; 503; 603), a second opening (209) formed at a bottom side of the bowl (203; 303; 403; 503; 603), an inner wall (211; 311; 411; 611) extending from the first opening (207) to the second opening (209) about the longitudinal axis, and a shoulder (213; 313; 413; 613) disposed on the inner wall (211; 311; 411; 611) that extends towards the longitudinal axis with respect to the inner wall (211; 311; 411; 611). A top surface (215; 315; 415; 615) of the shoulder (213; 313; 413; 613) is angled upwardly in a radially inward direction with respect to the longitudinal axis. The apparatus (201; 301; 401; 501; 601) further comprises a plurality of slip assemblies (221; 321; 421; 621) movably disposed within the bowl (203; 303; 403; 503; 603) and having a tapered inner surface (223; 323; 423; 623) with respect to the longitudinal axis.
