Support assembly for a core drill

Abstract

A support assembly for a core drill which utilizes an improved high strength spoked reinforcer. The reinforcer may be removably mounted a core drill tube by fasteners. A drive connection is removably mounted and centrally located on an outer disc of a pair of discs. The drive connection is adapted to connect with a drive shaft to cause rotation of the tube. The assembly can also include a split in the disc when the high strength spoked reinforcer is not welded thereto, thereby providing a means of water control. The high strength spoked reinforcer can be a separate piece that is bolted to the disc or can be integrally formed as one piece therewith.

1 . A drive assembly having a reinforcement structure for a tubular core drill, the drive assembly comprising a tool coupling element having an axis aligned with a center axis for receiving from a first direction a drive tool element for a core drill, a structure for supporting a cylindrical core, a plurality of non-planar extensions extending from an area near a center of the tool coupling element to an area adjacent the structure for supporting the cylindrical core.
