Description
Technical Field
[0001] This utility model belongs to the technical field of mining belt conveyors, specifically relating to an intelligent automatic tensioning protection device for mining belt conveyors. Background Technology
[0002] Intelligent mining belt conveyors are modern transportation equipment integrating advanced sensing technology, automated control, and data analysis. Widely used in the mining industry, they efficiently and safely transport materials such as ore and coal. The equipment uses sensors installed at key locations to monitor belt speed, tension, temperature, belt misalignment, and the operating status of rollers and idlers in real time, ensuring stable system operation. Employing a programmable logic controller (PLC) as the core control unit, it automatically adjusts drive power, braking system, and belt correction devices based on preset programs and real-time data, effectively reducing energy consumption and failure rates. Intelligent mining belt conveyors are also equipped with a remote monitoring and fault diagnosis system. Operators can view equipment operating parameters, historical data, and video feeds in real time at the control center via industrial Ethernet or wireless network. In the event of an anomaly, the system immediately issues an alarm and automatically takes emergency measures, while simultaneously pushing fault information to maintenance personnel's mobile terminals for rapid response and precise repair. Furthermore, this equipment supports seamless integration with other intelligent systems in the mine, such as data sharing and collaborative operations with mining equipment, warehousing systems, and dispatch centers, building a complete intelligent production chain for the mine, significantly improving production efficiency, reducing operating costs, and ensuring personnel safety. The application of intelligent mine belt conveyors marks a solid step forward in the mining industry's transformation towards digitalization and intelligence.
