Detailed introduction
Belts and joints have different degrees of wear and aging, and the white conveyor belt has increased with the use of years. In view of this situation, the method of artificial flaw detection was used to detect. Artificial flaw detection is the method of visual inspection, directly observe the shape of the belt, see whether there are abnormal changes such as bubbling, mark the joint of the belt and measure with a steel ruler to determine whether the damage has changed, whether the belt joint is extended, and detect the damage of the belt. This is the most original detection method, although the mechanical and electrical maintenance personnel can see the changes on the surface of the belt, they can not explore the changes inside the steel rope core belt. The belt tearing and breaking accident usually stems from changes in the white conveyor belt, such as tapping of the steel rope core joint, rust or vulcanization process problems. When the surface does not change and the internal problem occurs, the visual method is difficult to detect. When the belt distance is long, this method has a long measurement period and a high error rate of the guard belt, which can not effectively ensure the safe operation of the belt transportation system. Therefore, it is of great significance to adopt on-line flaw detection and monitoring technology to strengthen the maintenance of steel rope core belt conveyor for safe and efficient production of belt transportation system. 2-line inspection and monitoring technology This technology uses X-ray and related processing software to carry out non-contact, on-line, real-time inspection of the steel wire core conveyor belt. It can realize the detection in the state of no stop, load and no load, not only can detect the movement and displacement of the steel wire rope core in the street of the conveyor belt, as well as the safety hazards such as broken rope, fatigue and rust that may lead to broken belt accidents, but also can accurately locate the problem parts. The use of technology can effectively reduce the use and maintenance costs of steel rope core conveyor belt and improve the production efficiency of coal mine.

Ultra-wide conveyor belt detection method: line real-time detection; 2 Detection belt speed: 110m/3 joint displacement detection accuracy (non-elastic change) ≥99%4 Internal strand break detection accuracy: ≥99%5 steel wire rope core fatigue, rust detection accuracy: ≥99%6 Longitudinal positioning error distance: ≤10mm2.1 Equipment composition The monitoring device with this technology is composed of: X-ray emission box, X-ray receiving box, control box and computer box, to achieve the following functions: 1 sensor part, to complete the rope core conveyor belt joint or broken signal pickup; 2 Signal transmission part, complete the sensor signal to the computer transmission; 3 Computer detection part, the realization of the input signal acquisition, analysis, processing, output, and get the corresponding results. 2.2 Working Principle The detection of the monitoring device applying the online flaw detection and monitoring technology is based on the principle of X-ray penetration. After the X-ray emitted by the product launching system penetrates the steel rope core conveyor belt, it is accepted by the receiving system placed on the other side of the conveyor belt. The highest detection accuracy of the receiving system can reach 0.4mm. In real time, the picture of the wire core is restored and the picture is fed back to the remote terminal display. The monitoring device uses X-rays, which mainly take advantage of their penetrating properties. Penetration refers to the ability of X-rays to pass through a substance without being absorbed.
