Abstract

The detection of the spindle attitude for the mine hoist stands as a critical component within the scope of deformation monitoring in the coal mine industrial square. To tackle the challenges arising from considerable measurement space, stringent accuracy requirements, and insignificant feature elements, a combined measurement method is introduced, with the laser tracker as its nucleus. This method enables the dynamic tracking measurement of the circular running trajectory of the hoist's double-side profiles with the help of a laser tracker. Subsequently, through fitting procedures, the three-dimensional coordinates of the hoist spindle are calculated. In the aftermath, it facilitates the resolution of attitude parameters such as the inclination angle and the deflection angle of the hoist. Empirical observations demonstrate that the measurement error of the laser tracker's running trajectory is superior to ± 0.1 mm. Additionally, the residual of coordinate transformation between the winch room and the industrial square remains within ± 0.8 mm. In comparison with the conventional combined measurement method utilizing theodolite intersection, this approach enhances working efficiency by over twice the previous rate.
