As for the re-claimer with 6 000 t/h loading ability, which was brought into operation in the first-phase coal terminal of Huanghua Port ten years ago, its rotary support rail often distorts and collapses in the operation, and has to be replaced by new one twice or more per year. Based on the above case, the cause of rail damage is investigated by calculating the deadweight of re-claimer and the rotary wheel pressure under overloading working condition. The existing problems of the re-claimer rotary wheel and its rail are researched deeply. In addition, the solution is proposed, which will provide the reference for the safety operation and maintenance of the machine.%投产10 a的黄骅港煤码头一期工程6 000 t/h取料机的回转支撑轨道在作业过程中经常变形或塌陷,其更换频率为2次/a以上.以此为研究对象,通过计算取料机整机自重和重载工况下回转轮的轮压,探讨轨道损坏的原因.就取料机回转车轮和轨道存在的问题进行深入研究,并提出解决方案,可为该类设备的安全使用和维护提供参考和借鉴.
