Buoy split key removal device

摘要

A buoy split key (“BSD”) removal apparatus, system, and method are disclosed. The BSD utilizes a power screw to apply a steady and controllable compressive load onto the split key. The BSD applies a compressive force or load to the bitter ends of the split key in order to maximize the use of the moment on the split key. The spread and/or twisted split key is compressed by a compression assembly and compression power screw as supported by a compression frame. The compression assembly provides steady and controllable compression on a buoy split key. A compression power screw and extrusion power screw should be threaded in the opposite direction for maximum torque to remove the buoy split key. Once the split key is fully compressed by the compression assembly, the compressive load from the power screw and split key are then removed.

主权项

1. A buoy split key removal apparatus, comprising:
a compression assembly comprising a compression cart and a compression power screw, wherein said compression cart grips a pin back rest of a buoy split key, and said compression power screw compresses said pin back rest of said buoy split key and said compression power screw is thereafter released; and an extrusion assembly comprising an extrusion cart and an extrusion power screw, wherein said compressed buoy split key is lined up with said extrusion cart and wherein said extrusion power screw moves in an opposite manner of said compression power screw, thus releasing said buoy split key.
