摘要
针对河钢宣钢推焦刮板机存在的链条磨损、焦炭烧链条、刮板弯曲、链轮处掉链等现状,进行了故障原因剖析,并采取了相应的措施。通过改变刮板机机槽机头架结构、刮焦方式,在刮板背部加筋,增加链条压紧装置,刮板机的使用寿命得到有效延长,抗弯曲能力明显提升,易损件(刮板、连接环)由原来每年更换3次减少到每年更换1次,抢修、检修频率由年20次减少到年4次,大大减轻了维修成本及劳动强度。
In view of the chain wear, coke burning chain, scraper bending and chain dropping at the sprocket of the pusher scraper in HBIS Xuansteel, the causes of the failure are analyzed and the corresponding measures are taken. By changing the structure of the head frame of scraper, changing the coke scraping mode, reinforcing the scraper back, and adding the chain pressing device, the service life of the scraper has been effectively extended, the bending resistance has been significantly improved, the vulnerable parts(scraper, connecting ring) have been replaced from 3 times a year to 1 time a year, and the frequency of emergency repair and maintenance has been reduced from 20 times a year to 4 times a year, which greatly reduces the maintenance cost and labor intensity.
