Abstract
Steel core belts are widely used in long-distance, large capacity, large angle of mine, metallurgy, port, electricity and other departments of the large-scale transportation systems. According to incomplete statistics, this kind of belt accident 93.75% occurred in the joints and most are due to joints tic was not timely detected. Hence, non-destructive detection of belt is the key to the whole transportation system’s safety. For steel core belt automatic detection technology, deep research has been carried out at home and abroad. Detection apparatus was developed based on the electromagnetic theory and principle of X-ray, however, some varying defects existed in the industrial applications. Automatic detection apparatus of steel cord conveyor belt, developed by Pingdingshan Industry Polytechnic College and Shanxi Huaning Beier Measurement & Control Co. Ltd., integrated both advantages of electromagnetic detection and X-ray detection. It overcomes the difficulties of X-ray machine explosion proof and long time radiation. This kind of automatic detection apparatus has been installed and worked well in more than 30 mines and achieved good economic and social benefits since it was installed in Zhong Ping Energy Chemical Group’s 12th main slope conveyor.
