180/50/10t四梁桥式铸锭起重机主起升机构断轴事故原因探讨

Discussion of Reason of Axle Breaking of the Key Lifting Mechanism for 180/50/10 t four Beam - Ingot Charging Bridge Crane

分析了180/50/10t四梁桥式铸锭起重机在满负荷升降时,两棵高速万向联轴器突然断裂,造成整包钢水坠落的原因,对关键部位的受力情况进行了分析和计算。采取了轻型更换为重型万向联轴器等安全措施,实施后提高了设备安全可靠性,至今运行正常,保证了安全生产。

Sudden breaking of two high speed universal cou- pling resulted in the molten of whole ladle dropping when 180/ 50/10 t four beam- ingot charging bridge crane is full- load lifting. The accident reason is analyzed. The force of the key parts is calculated. Taking the safe measurements of substitu- tion of heavy universal coupling for light universal coupling can improve the safety and reliability of equipment and ensure the normal operation and safe production.
