AI Technical Summary

Technical Problem

Existing mining hoisting equipment suffers from high energy consumption, short service life, low efficiency, and insufficient reliability, especially in terms of drive type and structural design.

Method used

The device employs a coaxial dual-self-driven synchronous control permanent magnet external rotor lifting mechanism. By using a shared coaxial shaft for the two permanent magnet external rotor lifting structures on the left and right sides, and equipped with water-cooled circulation components and precise control methods, including PLC control, cross-coupling adaptive control, and neural network PID control, it achieves synchronous rotation of the two drums and energy recovery.

Benefits of technology

It improves the stability and reliability of the lifting device, reduces energy consumption, extends service life, realizes the flexibility and efficient synchronous control of dual-load bidirectional transportation, and overcomes the heat dissipation and synchronization problems of traditional devices.
