Description

Technical Field

[0001] The utility model belongs to the technical field of on-line monitoring of steel wire rope core conveyor belts, and in particular relates to a novel X-ray real-time on-line monitoring device. Background Art

[0002] The steel cord conveyor belt is an important part of the belt conveyor for traction and transportation. The cost of the conveyor belt accounts for 30% to 50% of the total equipment cost. During use, the steel cord may break, scratch, rust, or elongate due to various reasons. Once a failure occurs, it will cause major safety accidents and casualties, resulting in huge economic losses such as production suspension and equipment damage, which will seriously affect production safety. Therefore, it is very important to take measures to prevent belt breakage accidents.

[0003] The earliest method used in China was manual inspection. Due to the long laying route, long transportation distance and many types of faults of belt conveyors, if only manual inspection is used to remove or determine belt conveyor faults, problems such as low efficiency and long time consumption will inevitably occur. With my country's accession to the WTO, many advanced technologies from abroad have flowed into China, including some advanced monitoring instruments and fault diagnosis methods. Since these monitoring technologies and equipment management software are very expensive, many companies cannot use this advanced technology and can only rely on the original inspection methods for inspection.

[0004] Wu Tao et al. studied the architecture and principle of the belt conveyor automation system, and analyzed the improvement and promotion methods of various key sensors, and achieved remarkable application results. In their technical description, the belt conveyor automation system architecture includes components such as sensors, data collectors, computers and displays. The sensor is used to collect data from the conveyor belt, the data collector processes and analyzes the data, and the computer automatically determines the type of fault of the conveyor belt based on the analysis results and displays the fault information on the display. The accuracy and efficiency of the system can be improved by improving and promoting various key sensors. However, the research on belt conveyors in the above literature is limited to equipment monitoring and control and remote monitoring, and has not yet been upgraded to fully automatic online monitoring of belt conveyor faults. In a belt conveyor, the conveyor belt is an important component for its traction and load-bearing.

[0005] Disadvantages of existing technology:

[0006] 1. Sensors are easily affected by environmental factors such as temperature, humidity, vibration, etc., which may lead to inaccurate data collection;

[0007] 2. The processing power of data collectors and computers is limited and may not be able to process large amounts of data, resulting in inaccurate analysis results;

[0008] 3. Harmful to the human body. The X-rays used in X-ray real-time monitoring technology have certain radiation damage to the human body. Long-term exposure to X-rays may increase the risk of cancer and other diseases. Therefore, appropriate protective measures are required when using this technology to ensure the safety of staff and examinees.

[0009] 4. For some complex faults, the system may not be able to accurately determine the fault type and manual intervention is required.

[0010] In the past, the monitoring of steel cord conveyor belts mainly relied on manual work, which required stopping the machine and only relying on the naked eye to observe the surface of the conveyor belt. Not only was the efficiency low, but it was also difficult to find internal damage and defects in the conveyor belt, which posed a huge safety hazard. The online monitoring technology for steel cord conveyor belts effectively solved the above problems. This technology is a non-destructive flaw detection technology recently developed in China. It can quickly and accurately monitor the operation of the conveyor belt, effectively prevent the occurrence of belt breakage accidents, and provide protection for safe production.

[0011] The conventional equipment management system is actually an offline management with relatively low efficiency. Managers at all levels cannot grasp the information of equipment operation in the first place. Instead, they need to input hidden dangers and equipment information manually, or verbally inform personnel at all levels of the equipment operation status. The response speed is relatively slow, and the equipment operation information is not comprehensive and there is a large lag. The optical detection of this new detection equipment is a device for implementing detection. Utility Model Content
