Abstract: Un dispositivo de cuña incluye un alojamiento que forma un barreno axial, un juego de cuñas superior separado axialmente sobre un juego de cuñas inferior, y un accionador de cremallera y piñón que mueve de manera radial el juego de cuñas superior y el juego de cuñas inferior entre una posición retraída y una posición extendida para sujetar un tubular dispuesto en el barreno; el juego de cuñas superior y el juego de cuñas inferior pueden orientarse para resistir el movimiento descendente de los tubulares sujetados y para permitir el movimiento ascendente del tubular sujetado; uno del juego de cuñas superior y del juego de cuñas inferior puede estar orientado para resistir el movimiento ascendente del tubular sujetado y el otro del juego de cuñas superior y del juego de cuñas inferior puede estar orientado para resistir el movimiento descendente del tubular sujetado.

Abstract: A slip device includes a housing forming an axial bore, an upper set of slips spaced axially above a lower set of slips, and a rack and pinion actuator radially moving the upper set of slips and the lower set of slips between a retracted position and an extended position to grip a tubular disposed in the bore. The upper set of slips and the lower set of slips can be oriented to resist downward movement of the gripped tubular and to permit upward movement of the gripped tubular. One of the upper set of slips and the lower set of slips can be oriented to resist upward movement of the gripped tubular and the other of the upper set of slips and the lower set of slips can be oriented to resist downward movement of the gripped tubular.
