ABSTRACT:
A drive rod centralizer suitable for use with a roof bolting drill is described. A roof bolting drill, which includes a drive rod mounted on a drive head, has a support frame connected thereto that is disposed over the drive rod. The support frame includes a plurality of supporting members which are positioned such that a roof bolting plate or board may be slidably received within the supporting members whereby the central bolt hole of the bolting plate is aligned with the drive rod of the roof bolting drill. By this arrangement, the drive rod passes through and is guided by the bolt hole in the plate, thereby centralizing the drive rod during a drilling operation.
