1. An omnidirectional slip bowl comprising:
a support frame having a central axis and defining an opening therein to receive a tubular passing into or coming out of a wellbore;
a plurality of pivot arms for moving between an open configuration and a closed configuration;
a plurality of cylinder mounts slidably engaging the support frame and moving between the open configuration and the closed configuration, each of the plurality of cylinder mounts associated with one of the plurality of pivot arms;
a plurality of actuators each having a first end connected to one of the plurality of pivot arms and a second end connected to one of the plurality of cylinder mounts, wherein each of the plurality of actuators moves the associated pivot arm and the associated cylinder mount between the open configuration and the closed configuration;
a plurality of pipe inserts for engaging the tubular in the closed configuration to prevent the tubular from moving perpendicular to the central axis of the support frame;
a plurality of carriers each associated with one of the plurality of pivot arms having a first side for supporting a pipe insert of the plurality of pipe inserts and a second side defining a first plurality of alternately angled surfaces, wherein a first portion of the first plurality of alternately angled surfaces are angled in a first direction and a second portion of the first plurality of alternately angled surfaces are angled in a second direction;
a plurality of slide plates, each of the plurality of slide plates having a first side for engaging a corresponding surface on one of the plurality of pivot arms and a second side defining a second plurality of alternately angled surfaces, wherein a first portion of the second plurality of alternately angled surfaces are angled in the first direction and a second portion of the second plurality of alternately angled surfaces are angled in the second direction;
wherein when the plurality of pivot arms are in the closed configuration and the tubular is moving out of the wellbore, the plurality of slide plates move in a third direction along the plurality of pivot arms and the first portion of the second plurality of alternately angled surfaces angled in the first direction of the plurality of slide plates engage the first portion of the second plurality of alternately angled surfaces angled in the first direction of the plurality of carriers to cause the plurality of pipe inserts associated with the plurality of carriers and the plurality of slide plates to more firmly engage the tubular to prevent the tubular moving out of the wellbore; and
wherein when the plurality of pivot arms are in the closed configuration and the tubular is moving into the wellbore, the plurality of slide plates move in a fourth direction along the plurality of pivot arms and the second portion of the second plurality of alternately angled surfaces angled in the second direction of the plurality of slide plates engage the second portion of the second plurality of alternately angled surfaces angled in the second direction of the plurality of carriers to cause the plurality of pipe inserts associated with the plurality of carriers and the plurality of slide plates to more firmly engage the tubular to prevent the tubular moving into the wellbore.
