摘　　要：介绍国内外带式输送机张紧装置的功能及各自的特点,以及在煤矿井下应用中存在的问题。通过分析提出动态自动张紧的控制策略,基于电机电流与负载有一一对应的关系,利用变频技术作为技术关键达到动态控制的目标。A brief description of the performances and respective characteristic of take - up devices for belt conveyor in the world is showed, and the problems that exist during used in coal mining are also introduced. Based on the analyses, the control strategy of dynamic automatic take - up is brought forward, which is based on the correspondence relationship of electrical current and load of the electromotor, moreover using the technology of frequency conversion as know - how to bring the dynamic control to success.
