摘　　要：冶金行业炼铁烧结矿主要以铁精粉矿为主,用料量大,目前主要以20 t双桥式抓斗起重机为上料的重要设备,4 m^(3)抓斗使用强度高。为了延长重型抓斗的使用寿命,使四绳双瓣重型抓斗在冶金行业装卸作业中具有更好的稳定性能,针对传统四绳双瓣抓斗设计中的几个关键部位,通过日常点检维修、优化改进和实践检验的方法,验证了关键结构设计、制造的可行性。运用该方法可提升四绳双瓣重型抓斗的稳定性、可靠性,大幅降低生产过程的故障率,从而有效提升抓斗的作业率。Iron sinter in metallurgical industry is mainly iron concentrate powder,and a large amount of material is used.At present,20 t double-bridge grab crane is an important equipment for feeding,4M^(3) grab use strength.From the traditional four-rope double-valve grab construction,the technical optimization and improvement measures and manufacturing requirements of the key parts of the grab construction are expounded.This method can improve the stability and reliability of the four-rope double-valve heavy grab,greatly reduce the failure rate of the production process,so as to effectively improve the operation rate of the grab.
