Automatic Detection Apparatus Development of Steel Cord Conveyor Belt

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.

Identification of Selected Failures in a Pipe Conveyor’s Operation with the Use of the Discrimination Method Based on Continuous Measurement

“…The principle of discrimination is that, based on different combinations of CF values at three positions, one of the properties is assigned to the device: failure-free state, missing roller including its position, or other failures. Compared to the results presented in [21][22][23][24][25], the solution is more complex and more innovative. However, this research did not examine a single method application to identify one type of damage.…”

“…Until now, most of the presented papers have dealt with the detection of various failures in continuous transport systems, for example, [21][22][23][24][25]. Their common feature is the use of specific methods to identify various types of failures in continuous transport systems.…”

Belt Tear Detection for Coal Mining Conveyors

“…As a typical NDT method, X-ray detection is widely used to construct and analyze internal images of samples. X-ray based NDT methods [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ] used in online industrial inspection require special designs since X-ray has the characteristics of high penetration and can be harmful to human beings. In simple terms, the X-ray goes through the running conveyor belt, and the intensity of radiation received on the other side constantly fluctuates in a fixed range if the conveyor belt is in good condition.…”
