衡阳市第二汽车配件厂,用单轨加料机对冲天炉加料,由于钢丝绳放松后不能正常归槽,经常出现电葫芦卡钢丝绳现象。轻者影响正常加料,使铁水温度下降。重则卡断钢丝绳,影响正常生产。在单轨加料机上增加一个弹簧缓冲装置后,完全杜绝了卡钢丝绳的现象。弹簧缓冲原理如图,在加料桶被提升时,弹簧处于拉伸工 Hengyang City, the second auto parts plant, with a single-track feeder feeding cupola, the rope can not be normal due to the relaxation after the groove, often appear hoist card wire rope phenomenon. Light affect the normal feeding, so that the molten iron temperature drops. Heavy off the wire rope, affecting normal production. Add a spring buffer device on the monorail feeder, completely eliminate the phenomenon of the card wire rope. Spring buffer principle shown in Figure, when the bucket is raised, the spring is stretched
