摘要

为了水泥生产过程的顺利进行,有必要对生产的各个组成部分进行维护。在水泥的维护和生产中起重要作用的工具之一是桥式起重机,它是一个独立的提升机构和一个框架的组合,可以自由悬挂或连接到起重机本身来提升和移动负载。桥式起重机出现的问题包括由于电机连接错误导致电机旋转方向相反,由于电源断开导致电机无法启动,由于超过最大容量的起重操作导致大梁发生弯曲(弯曲),这也会加速使用寿命。大梁在运行过程中,由于工作量大,对车轮产生磨损。由于需要很长时间的使用,因此需要定期维护,使其能够长期处于正常状态。支撑起重机整体重量的主要部件是轨道和车轮。本文讨论了水泥厂中由于钢轨和车轮之间的接触而发生的故障分析。失效分析是通过测试车轮和被认为已经失效或不再适合使用的支柱的硬度来完成的。然后用硬度测试数据和有关车轮和钢轨的文献研究回顾直接现场观察的结果。之后得出的结论是,该公司考虑采购轨道和车轮。得出的结论是:钢轨的硬度值低于车轮的硬度值。导致钢轨失效,必须更换钢轨。

Analisis Kegagalan Permukaan Kontak Rail dan Wheel pada Overhead Travelling Crane
For the sake of the smooth process of cement production, it is necessary to maintain each component of the production. One of the tools that play an important role in the maintenance and production of cement is the Overhead Traveling Crane, which is a combination of a separate lifting mechanism with a frame to lift and move loads that can be hung freely or attached to the crane itself. The problems that arise in the Overhead Traveling Crane include the reverse direction of the motor rotation due to an error in the motor connection, the motor cannot start due to a disconnected power supply, the occurrence of bending (curving) on ​​the girder due to lifting operations that exceed the maximum capacity which can also accelerate service life. of the girder, wear on the wheel due to high workload during operation. Due to the need for very long use, periodic maintenance is needed so that it can be in normal condition for a long time. The main parts that support the overall weight of the crane are rails and wheels. This journal discusses the analysis of failures that occur due to contact between rails and wheels that occur in a cement factory. Failure analysis is done by testing the hardness of both the wheel and the rely which is considered to have failed or is no longer suitable for use. Then review the results of direct field observations with data from hardness tests and literature studies related to wheels and rails. after that it was concluded that the company considered for the procurement of rails and wheels. The conclusion obtained is that the hardness value on the rail is lower than on the wheel. Resulting in failure of the rail so that the rail must be replaced.
