ABSTRACT:
The locating of the local centre of rotation of a cylindrical body from outside the body, while the body is rotating upon supporting bearings is carried out using a number of distance-measuring diode lasers mounted upon a movable chassis. Such determination of local centres of rotation can be used in the case of hot kilns to re-align the supporting sets of bearings upon which the kiln is rotatably supported. The integrated triangulation monitoring chassis is located in sequence at respective axial stations located along the kiln, adjacent the supporting bearings, and at each station a simultaneous single set of readings from three diode lasers to the shell surface enables a computer to calculate the location of the centre of rotation relative to the chassis. The location of the chassis, relative to a selected datum, is determined by the use of an integrated total station theodolite, which is repositioned, as required, to enable it to access and locate the chassis. A pair of prism reflectors mounted to the chassis facilitate the action of the theodolite, remote radio control being used to align the respective prisms towards the theodolite, in reflecting relation therewith. With each relocation of the theodolite datum its location relative to the original datum is determined, so that the derived centre distances, as measured by the diode lasers, can be plotted in true relation with a common datum, enabling ready determination of the corrections to the supporting bearings that are necessary, in order to achieve a unified axis of rotation for the kiln.
