Background technique

In the installation process of ring track, ring frame and other series of ring equipment of sintering ring cooler, the alignment measurement of ring track equipment has the characteristics of many measurement points, long measurement duration and high precision requirements. During the entire installation process of the sintered 102 square meter ring cooler, there are 330 points that need to be measured by the ring center point, including 38 points on the ring cooling frame, 38 points on the columns, 126 points on the horizontal track beam, and 96 points on the ring horizontal track Points, 58 points on the circular side rail, and 12 points on the curved track. According to the national standard, the error range of each point is ±2mm, and the pulling force of the ruler must be 50N.

At present, the ring track equipment is mainly measured by the following measurement methods: use theodolite to find the center point of the ring cooler, pre-embed a permanent center mark, one worker pulls one end of the tape to align with the center point, and another worker pulls the tape The other end of the measurement point required for measurement.

There are following deficiencies in the above-mentioned method:

(1) Aligning one end of the tape measure to the center point is manual operation, and the accuracy is not easy to guarantee; (2) There are many measurement points, the measurement duration is long, and the tape measure needs to be tightened for each measurement, which is likely to cause fatigue of the center point personnel and affect the measurement Accuracy; (3) The traditional method can only measure ring-shaped equipment on the same elevation, and does not have the function of adjusting the center point up and down, but the circular horizontal track, circular side rail, curved rail, track beam and rack are not on the same elevation. ;(4) Each measurement requires a worker to climb to the center marking table to align the center point, which not only consumes a lot of manpower and time, but also has potential safety hazards during the climbing process; (5) Measure each measurement When pointing, it is necessary to confirm whether the workers at the end of the center point are aligned. Small ring coolers can also be confirmed through loud dialogues, but the radius of large ring coolers is usually tens of meters, making confirmation difficult and inefficient.
