Abstract
The invention relates to a steel cord belt flaw detection system and a detection method therewith. The system is characterized in that: a magnetizer distributing at the front of the steel cord belt and a detection sensor distributing at the back of the steel cord belt are connected with an underground fiber receiver, a ground fiber receiver, an underground computer, and a ground computer. The method comprises the following steps: a steel cord array in a magnetized belt of the magnetizer generates a stray field when detection is performed; the detection sensor detects magnetic signals and converts the magnetic signals to electrical signals; the electrical signals are sent to the underground computer after pretreating and carrying out digital/analog conversion; an analysis result of the underground computer is sent to a belt conveyor operation controller; and the other result is sent to the ground computer through the underground fiber transceiver, optical cables and the ground fiber transceiver. By adopting the system and the method of the invention, the magnetizer and the detection sensor are stationary when the adhesive tape normally operates. When defects appear, a belt conveyer is stopped through the belt conveyer operation controller, detection data are sent to the ground computer through the ground fiber transceiver, the underground fiber transceiver, and the communicating optical cables to analyze, display and store. The system of the present invention which is convenient to manufacture and use can monitor in real time and accurately detects damages of strand break, cord break, splice displacement and the like.
Description
Technical field
The present invention relates to a kind of to disconnected strand, the disconnected rope of the wire rope in the steel cable belt, the technology that the splice slippage is carried out Non-Destructive Testing.
Background technology
Belt feeder is the common continous way transportation equipments of enterprise such as metallurgy, electric power, mine, steel cable core conveying belt is its critical component, at work, steel cable core conveying belt need to bear repeated stock and the friction of the initial materials such as ore, coal, will occur damage after having used a period of time.Conveying belt can not endless, and the form that often adopts the conveying belt of regular length to knit from beginning to end finally forms the conveying belt of ring-type.Owing to be not one-piece construction, the performance of conveying belt can be greatly affected, and wherein the woollen yarn knitting position between conveying belt and the conveying belt is the weakest link.After cycle, the splice position will occur loosening conveying belt at bearing certain pressure and pulling force, and the loosening direct result of splice is that load-bearing capacity descends, and after the slippage of splice reached certain numerical value, conveying belt can fracture.Wire rope in the steel cable core conveying belt is carried out the full tunnel monitoring, also do not have at present effective way, its main cause is as follows: wire rope is embedded under the rubber layer, and conventional method can't be found its change conditions; Wire rope in the section of conveying belt has tens of, even over one hundred more than, therefore, monitoring system data volume to be dealt with is huge, it directly has influence on follow-up signal processing and analyzing, relies on merely existing equipment can't satisfy the monitoring requirement of big data quantity and real-time.
And the rays method that adopts now, though be a kind of method of ripe inspection metal inside situation, but for steel cable core conveying belt, three-dimensional wire rope is projected on the film of two dimension, the loosening of joint can't be differentiated at all, and it is too many to add joint, may not realize the comprehensive monitoring of joint, therefore, a large amount of undetected inevitable;
