刮板输送机伸缩机尾自动控制系统设计

Auto Control System Design of AFC's Extendable Tail Frame

分析输送机运行过程中链条张紧力变化规律,根据机尾链轮松边链条的运动特点,提出检测链条张紧力的有效方法,对伸缩机尾自动控制装置进行了初步设计。

Analyses the changing character of chain tensioning force during conveyor running, advances a new way to measure tension according to the movement character of chain at return end of the tail frame,designs the auto control system of the AFC＇s extendable tail frame.
