矿山大型胶带运输机驱动装置改造实践

胶带运输机以其输送距离长、安全可靠、经济适用等优点被广泛应用于大型矿山矿石运输中。针对内蒙古矿业公司选矿厂钢芯胶带运输机运行过程中由于共振作用引起的电动机轴承频繁损坏的问题,对驱动装置进行改造。选择在地面新建驱动机房,将驱动装置位置下移,采用变频器启动的软启动方式,从根本上解决了电动机轴承频繁损坏的问题,设备运转率达到98%,3年多来,设备运行平稳,安全可靠。

Modification of driving device of large-scale conveyor belt in mines

The conveyor belt is widely used in ore transportation of large-scale mines for its long transportation range,safety,economic applicability. Because of the resonance, the electric motor bearing is frequently down in the steel core transportation operation of conveyor belt in the ore-dressing plant of Inner Mongolia Mining Co.,Ltd.. In light of that,the option is: the driving motor station is set up on the ground,the driving device is moved down and the soft start of the frequency converter is adopted. The existing problems are solved fundamentally. The operation rate of the equipment is 98 %. For 3 years,the equipment has been running steadily and is safe and reliable.
