Self-aligning plug removal and installation system and method
View Patent ↗A plug removal and/or installation system 400 , which has a structural framework configured to support a removal assembly and that, allows approximately one axis motion of the removal device. The removal device is configured with a plug attachment device that is configured to pass through a lower framework structural opening. The structural framework is configured to movably self align so that the removal device exerts approximately a linear force on a plug 300 along an approximately single axis 335 parallel to a plug central axis.
1. A plug removal system, comprising:
a movable structural framework member configured to support and non-fixedly attach to a pull device to apply a force in a plug single axis to a non-threaded, tapered plug so that the plug moves along the plug single axis;
the structural framework member is configured to movably self align so that the framework member exerts a linear force on the plug along the plug single axis;
a force application assembly including a push/pull device and/or a flexible assembly;
the push/pull device comprises a threaded rod configured with a non-fixedly attached t-handle; and
the flexible assembly includes a shackle that is non-fixedly attached to the push/pull device with a bolt passing through a hole in the second end of the threaded rod, a clasp hook configured to rotate that is non-fixedly attached to the shackle, and a lanyard loop assembly that is non-fixedly attached to the rotating clasp hook.
2. The plug removal system of claim 1 , wherein the structural framework member further comprises:
a top plate;
a bottom plate with a circular opening;
a bottom plate lower surface is low friction material; and
an intermediate support structure configured to fixedly attach the top plate to the bottom plate.
3. The plug removal system of claim 2 , wherein:
the structural framework is made from materials comprising metal, steel, stainless steel, composites, plastics, aluminum, PVC, wood or any combination thereof; and
the bottom plate lower surface is made from materials composites, plastic and PVC.
4. The plug removal system of claim 1 , wherein the plug can further comprise manhole covers, sealing plugs for cone-type tie rod openings in concrete walls, conical plug in a preformed-formed shape for sealing blast holes open cut mining, cone shape flow meter plugs, or conical shaped plugs.
