工业起重机的安全性和性能优化

在生产或运输中吊装设备和货物是所有重工业的共同功能,由起重机执行。提高工作条件安全性和操作效率的动力意味着起重机对改善重工业的贡献越来越大。

一些最常见的工业起重机是桥式起重机和门式起重机。在这些起重机中,货物通过缆绳从一个夹持装置上悬挂下来,其作用就像一个钟摆。这些摇摆荷载是一个安全隐患,并在起重机结构上施加额外的应力。摇摆控制的解决方案是使用一个交流驱动器上的输入电机密切地调节运动。

杂交

使用柴油和电池储能的结合创造了机会,以减少高峰负荷,优化使用更便宜的非高峰电力,并在停电时维持运行。

  • 将消耗从电网转移到非高峰时段。通过在夜间非高峰电价下给电池充电,然后在工作日需求增加时使用存储的电量,起重机操作员可以使用时移来降低日常操作的电力成本。
  • 对输入功率进行峰值负载剃除。通过使用电池存储的功率来提高峰值负载需求,例如当在提升操作开始时需要高扭矩时,电动机可以屏蔽峰值负载需求。最终,这意味着起重机制造商可以根据常规负载而不是峰值负载来确定电机的尺寸。
  • 备用电源或断电启动。使用备用电池来代替可能由柴油发电机驱动的旋转备用。随着电池变得越来越便宜,在电力供应失败的情况下,将电池集成到起重机上作为备份的可行性增加了。
