基于变磁场的防止带式输送机驱动打滑装置

摘要

The paper discusses effective method for preventing drive slipping based on analyzing drive mechanism of belt conveyor, and proposes a variable magnetic field based drive slipping prevention device that can change tensioning force by adjusting the position of tensioning device. The device depends on speed sensor and control system to measure drum speed so as to determine whether conveyor belt is slipping and automatically adjust the tensioning force, which effectively solves dive slipping of the belt conveyor in the case of insufficient tensioning force or tension lagging.%在带式输送机驱动机理分析的基础上,讨论了防止驱动打滑的有效方法,提出了一种基于改变磁场大小,调整张紧装置位置从而改变张紧力防驱动打滑的装置.该装置利用测速传感器和控制系统实现滚筒速度测量,从而判断输送带是否打滑,自动调整张紧力大小,有效解决了在张紧力不足或张紧滞后情况下带式输送机驱动打滑的问题.
