基于状态监测的门机计划性预警维修管理机制

On Condition Monitoring Based Planned Warning and Maintenance Management Mechanism for Portal Cranes

门座式起重机是散杂货码头公司使用最为广泛的港口装卸设备,它担负着港口装卸的最主要任务。因此,门机工作性能的优劣、完好率以及维修成本的高低都直接影响着港口企业的生产任务与经济效益。然而,由于检测手段较少,故障隐患的诊断较难,导致门机在线故障频发,维修时间及成本大幅增加。为了将维修模式变被动为主动,我们尝试实施计划性预警维修机制,通过多种监测方式开展门机状态监测,合理利用生产空档,使故障隐患被及时处理,大幅减低在线故障停时及维修成本,同时保障生产,为公司创造经济效益。

Portal crane is the most widely used port handling equipment in bulk cargo wharfs.However,as there are less detection methods,the diagnosis of potential faults is difficult,and the on-line fault of the portal machine is frequent,therefore,the maintenance time and cost increase greatly.In order to change passive maintenance mode to an active mode,this paper describes the implementation of a planned maintenance warning mechanism.Through a variety of monitoring based on condition monitoring,the production gap was well used and hidden troubles were timely treated,which significantly reduces online shutdown and maintenance cost and guarantees enterprise benefit.
