摘要
分析了刮板输送机链条的常见故障及其产生原因,阐述了刮板输送机链条的预紧力计算过程,介绍了目前国内外5种主要的链条张紧力监控技术的原理和特点,即基于张紧力与功率或油缸压力关系的监控技术、基于链条悬垂量的监控技术、基于微应变的监控技术、基于滑模控制的监控技术、基于电流法的监控技术,总结了现有监控技术存在的不足,并从张力监控技术和自动控制技术两方面展望了链条张紧力监控技术的发展方向。
The common faults of scraper conveyor chains and its causes were analyzed.The calculation process of chain tension of scraper conveyor was expounded.The principles and characteristics of five main chain tension monitoring technologies at home and abroad were introduced,namely monitoring technology based on relationship between tension force and power or cylinder pressure,based on chain suspension,based on micro-strain,based on sliding mode control,and based on current method.The shortcomings of existing monitoring technologies were summarized,and the development direction of chain tension monitoring technologies was prospected from tension monitoring and automatic control technologies.
