桥式起重机车轮啃轨的分析和处理

Analysis and Treatment of Track-biting for Bridge Cranes

分析了由于轨道平行度超差、标高超差、车体变形、备件超差等各种原因引起的桥式起重机啃轨现象,并就不同的啃轨原因提出了相应的解决方案。特别介绍了利用调整车轮解决啃轨问题的方法,并对调整车轮时加垫铜皮的具体方法和步骤进行了详细的说明。

In this paper, the reasons of causing track-biting of bridge cranes are analyzed, including the out of tolerances of runway elevation, parallelism, spare part, and the framework transmutation. The corresponding solutions are given. In particular, the way to solve the track-biting by rectifying rail wheels direction is introduced. The specific methods and steps of filling copper in bearing housing during rectifying rail wheels direction are explained in detail.
