中文摘要：

在桥式起重机运行过程中经常会遇到啃轨问题,严重时会造成脱轨事故,因此。对轨道状态的定期检测十分重要。文中测量对象为长期处于高温、高湿度、强腐蚀工作环境下的100 t重载桥式起重机,利用全站仪和轨道行走机器人测量其2根轨道的跨距、单轨直线度和双轨高度差等参数,以此为依据对轨道的安全性进行评估,并给出其轨道整改建议。

英文摘要：

Rail gnawing is a common problem in the operation of bridge cranes, which can be serious sometimes and cause derailment, making regular track inspection especially significant. The object measured in the paper is a bridge crane with a load of 100 t operating in high-temperature, high-humidity and highly corrosive environment. Total station and railway walking robot are used for measuring parameters such as the span of two tracks, straightness of a track and the height difference of two tracks. Measured parameters are used to assess the track safety. The paper further proposes suggestions on track rectification.
