[0034] Working principle of this utility model:

[0035] Taking the measurement of the axis deviation of the side surface of the rotary kiln as an example, firstly, the laser emitter magnetic seat 3 of the laser emission assembly 25 is adsorbed on the side surface of one end of the rotary kiln axis. Since the bottom surface of the magnetic seat 3 is V-shaped, the line connecting the two V-shaped vertices is automatically parallel to the axis center line of the rotary kiln, driving the first support rod 4 to be perpendicular to the axis center line of the rotary kiln. Under the action of the weight 22, the surface of the base 18 is relatively parallel to the horizontal line. The groove 38 provided in the base 18 is loaded with the slope washer 33, and the slope of the slope washer 33 is consistent with the slope of the rotary kiln in the ideal state. Under the cooperation of the hinge joint 34 and the T-shaped locking bolt passing through the pin shaft hole, the relative position of the laser generator 17 is fixed, and the bottom surface of the laser generator 17 is tightly fitted with the slope washer 33. Under the intervention of the slope washer 33, the laser beam 27 emitted by the laser generator 17 is parallel to the center line of the rotary kiln in the ideal state, that is, a measurement reference line is created. A target 26 is adsorbed at the mirror image position of the laser emitting assembly 25 at the other end of the rotary kiln axis, so that the laser beam 27 passes through a laser through hole 11 set on the target plate 9. At this time, the laser beam 27 can be used as a measurement reference for the axis center line of the rotary kiln under ideal conditions, and this target 9 can be determined as a reference target.

[0036] Then, according to the measurement needs, the target 26 is adsorbed at different points, and the laser beam 27 is passed through the laser through-holes 11 on the target 26 at the same position as the reference target in sequence. The position difference between the laser through-holes 11 of the target plate 9 and the laser through-holes 11 of the reference target is measured, and the obtained value is the axis deviation data of the rotary kiln. The actual rotary kiln side axis can be obtained by drawing a chart.

[0037] The measurement of the axis deviation above the rotary kiln is consistent with the side measurement and will not be repeated here.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
