冶金铸造起重机安全制动器的设计改进

Design and Improvement of Safety Brake for Metallurgical Casting Crane

八钢钢渣系统使用的五台冶金铸造起重机安全制动器只能靠人工干预工作,当主起升出现超速、断轴等异常状况时,无法自动检测识别,存在安全隐患。文章介绍了针对五台冶金铸造起重机电控系统进行的设计改进并应用到生产中,保证了起重机安全运行。

Five metallurgical foundry cranes are used in the hot cinder system of Bayi steel,the safety brake can only work by manual intervention,when the main hoisting occurs abnormal conditions such as over-speed and broken axle,it can not be automatically detected and identified.This paper introduces the modification of the electric control system for five metallurgical foundry cranes,which has been improved and applied to production to ensure the safe operation of cranes.
