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.

Field[0003]The field of this invention relates generally toward cutting implements and more particularly to the construction of a core drill.[0004]2. Related Art[0005]Core drills are commonly used for drilling holes in hard materials, such as concrete and masonry. These holes are then used to support a structural member, such as a post, which is used on a support member for a building structure or for forming a large diameter borehole with the borehole being used for the passage of pipe lines or...

Benefits of technology

[0023]In another example of reinforcement, the reinforcement can include a slanted element. In the present configurations, “slanted element” will refer to a structural support element that is both nonparallel to the Z axis and to the X-Y plane. A slanted element improves structural support in the reinforcement when used with a device such as a core drill during operation of the core drill. In one example, a slanted element can be associated with a respective spoke, arm or extension for improving the strength of the structure. In another example, a slanted element can be formed monolithic with a spoke, arm or extension, for example in one configuration by extrusion, and in another configuration by forming metal into the desired structure. In a further example, a slanted element can be combined with an extension in the X-Y plane to form a combined extension, arm or spoke, and in another configuration a slanted element can be combined with an extension in the Z-axis direction to form a combined extension, arm or spoke. In another example, multiple slanted elements can be used to form an extension, arm or spoke for helping to form a support for a structure such as a core drill. In an additional example, at least one slanted element can be incorporated in an arm, extension or spoke in the form of a triangular-shaped channel or a triangular-shaped tube. A rectangular-shaped tube can also be configured in a reinforcement structure to have a slanted element. Additionally, a polygon structure having more than four sides can be configured to have a slanted element to assist in forming a support for a structure such as a core drill.

Problems solved by technology

Furthermore, there is a certain amount of deflection associated with the use of the core drill.
