地铁用带随车吊轨道平车线路试验中出现的问题及其解决方案

Problems and Solutions in the Test of Rail Flat Car with Mounted Crane for Metro

介绍地铁用带随车吊轨道平车的主要结构组成和主要技术参数。针对轨道平车样车在线路试验过程中出现的运输长钢轨时车组无法通过半径为65 m的S形曲线、抓轨器不能有效抓住钢轨、车组通过半径为65 m的S形曲线时U型吊与车轴存在摩擦或干涉,以及随车吊无报警装置等问题,通过分析研究,制定相应解决方案。现场运用表明,轨道平车的解决方案可行。

The paper introduces the main structure and technical parameters of the rail flat car with mounted crane for metro.In the process of rail flat car sample line test,there are some problems,such as the train crew cannot pass the S-shaped curve with a radius of 65 m when the long rail is being transferred,the rail grabby cannot grasp the rail effectively,the friction or interference between the U-shaped crane and the axle when the train crew passes the Sshaped curve with a radius of 65 m,and there is no alarm device for the on-board crane,etc.,the corresponding solutions are formulated based on analysis and research.Field application shows that the solution to the problem of rail flat car is feasible.
