冲天炉上料料斗卷扬机是用电磁离合器制动机组来驱动料斗上下运动的,为了防止突然停电而发生的危险,还装有弹簧闭合安全电磁制动器。使料斗卷上、卷下的金属绳绞盘通过离合器制动器组件由附有减速齿轮的可逆电机来驱动。卷上卷下的停车位置由限位开关来检测,假如料斗位置确定下来,限位开关就接通机组的制动器,从而准确地停止在所给定的位 Cupola feeding hopper winch is the use of electromagnetic clutch brake unit to drive the hopper up and down movement, in order to prevent the sudden power outages and the danger occurred, but also equipped with spring-closing safety electromagnetic brake. The hopper is wound up and the coiled metal winch is driven by a reversible motor with a reduction gear via the clutch brake assembly. The parking position on the roll is detected by the limit switch. If the hopper position is determined, the limit switch is turned on the brake of the unit to stop exactly at the given position
