摘要
针对矿用通风机叶尖间隙测量方法存在精度和自动化水平低等问题,对间隙测量技术、表征及评价方法等进行了研究,提出了一种基于2D激光测量的矿用通风机叶尖间隙测量方法。采用LS-100CN激光轮廓测量传感器采集了叶尖间隙几何信息,然后通过投影变换、特征提取等技术实现了叶尖间隙的高精度测量;采用叶片形位偏差、机壳形状偏差、综合叶尖间隙等参数,综合地表征和评价了通风机叶尖间隙的实际几何状态,得到了更全面、更科学的评价结果。研究结果表明:该方法具有精度高、非接触等特点,显著提高了测量的效率、精度和智能化水平。
Aiming at the problems of low accuracy,low automation level in the measurement methods of tip clearance of mine ventilator,a measurement method for tip clearance of mine ventilator based on 2D laser measurement was proposed.The geometric information of tip clearance was collected by a laser profile measurement sensor of LS-100CN,and the high-precision measurement of tip clearance was achieved by technologies of projection transformation and feature extraction.The parameters of form and position deviation of blades,form deviation of ventilator case and comprehensive tip clearance were used,the authentic geometric state of tip clearance was characterized and evaluated,and the more comprehensive and scientific evaluation results were obtained.The results show that the method has the characteristics of high accuracy and non-contact,and it can significantly improve the efficiency,accuracy and intelligent level of measurement.
