解析起重机械存在的不安全因素 Analysis on unsafe factors of heavy machinery 随着中国起重机械制造水平的不断提高,起重机械的效率和可靠性也在持续提高,但起重机械在实际运用中出现故障的情况仍较多,完善系统设计、做好定期维护、提高操作人员水平是提高起重机械可靠性的关键,总结经验,针对不同的故障采用针对性的方法对减少事故及提高工作效率也非常重要。 With the development of Chinese hoisting machinery manufacturing level unceasing enhancement, since the efficiency and reliability of heavy machinery continued to improve, but the hoisting machinery faults in practical application is more perfect, system design, complete the regular maintenance, improve the level of operating personnel is to improve the key, heavy mechanical reliability summary experience, in view of the different the fault using the targeted approach to reduce accidents and improve the work efficiency is also very important. 在企业里运用较为平凡的主要有电动葫芦、电动单梁起重机及通用桥式起重机。一般情况下生产型企业运用起重机械主要是在检 In the enterprise in the use of more ordinary mainly electric hoist, electric single girder crane and bridge crane. General production enterprise use of lifting machinery mainly in the examination 修的时候辅助使用,且运行环境较恶劣,使用率不高,但是故障率较高,据统计,检修用起重机械每年平均的使用次数约为6次,但是发生故障为1.2次,从而影响检修进度、增加维修费用及成本,且对检修时的安全埋下了极大的隐患。因此,判断起重机械的故障原因并采取有效的的措施预防其故障的发生就显得尤为重要。 When repairing auxiliary use, and the operation environment is very bad, the utilization rate is not high, but the failure rate is high, according to statistics, the overhaul by use of hoisting machinery annual average number is about 6 times, but failure is 1.2 times, thus affecting the maintenance schedule, increasing repair costs and cost, and the repair of the safety buried the huge hidden trouble. Therefore, judge fault reason of lifting and take effective measures to prevent the fault is particularly important. 1.起重机械的详细分类 A detailed classification of 1 hoisting machinery 目前,国内已经正式使用的起重机设备种类多样,从不同的角度对其进行分类的结果是不一样的。详细划分起重机的类别有助于了解各类设备的故障问题,引导操作人员掌握相应的机械性能,提高机械故障的故障防范意识,实现安全故障率的降低。常用的分类方式是参照机械结构划分,包括: At present, the domestic has been officially used crane species diversity, the results of its classification from the different angle is not t
