1. A multi-diameter thrust device, comprising:
one or more thrust cups, each thrust cup of the one or more thrust cups comprising:
a first axial end hub disposed at a first axial end of the thrust cup, wherein the first axial end of the thrust cup is configured to receive a flow of fluid;
a second axial end hub disposed at a second axial end of the thrust cup, wherein the second axial end of the thrust cup is configured to at least partially block the fluid from flowing axially past the second axial end of the thrust cup;
a plurality of bowsprings, each bowspring of the plurality of bowsprings having a first axial end portion coupled to the first axial end hub and a second axial end portion coupled to the second axial end hub, wherein the plurality of bowsprings are disposed circumferentially about a central axis of the multi-diameter thrust device;
a wheel arrangement connected to the one or more thrust cups via one or more support members, wherein the wheel arrangement is configured with a wheel with an exterior diameter that is configured to contact an interior diameter of a wellbore prior to a portion of the plurality of bowsprings;
a mandrel;
an internal rod, wherein the internal rod is disposed within the mandrel and is coupled to the first axial end hub by way of a first mechanical connection, and wherein the internal rod and the first axial end hub are configured to translate along the mandrel; and
the wheel arrangement is coupled to the internal rod such that when the interior diameter of the wellbore changes, the exterior diameter of the wheel is configured to change in accordance with the change in the interior diameter of the wellbore and translate the internal rod along the mandrel.
