2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this The most recent version of the document, including all modifications, applies to this document.

3 Principle of the method

3.1 vertical straightness measurement principle The use of a level to establish a horizontal datum, read from the ruler of the wheel or the cylinder is the highest point relative to the horizontal reference plane height, And according to the diameter of the wheel and the belt and the cylinder between the top gap, calculate the rotation of the kiln bearing the center of the cylinder in the vertical direction Relative height difference, the vertical straightness of the cylinder axis. 3.2 Horizontal Straightness Measurement Principle The use of the theodolite in the rotary kiln side of the establishment of a kiln and kiln tail wheel center of the center line parallel to the vertical reference plane, measuring wheel The horizontal displacement of the belt or cylinder relative to the vertical datum, calculate the horizontal displacement of the center of the belt or cylinder, and obtain the level of the cylinder axis Straightness.

4 measuring instruments

4.1 level. in line with GB/T 10156 requirements, the accuracy of ± 3mm/km. 4.2 optical theodolite. in line with GB/T 3161 regulations, not less than the national J6-class technical standards. 4.3 scale. accuracy of ± 1mm. 4.4 level (accuracy of 0.02mm /.200mm), shift ruler, steel tape, feeler (accuracy of 0.01mm). 4.5 vernier caliper (accuracy 0.02mm). ......
