The Track Inspection And Maintenance Technology Research Based On Zhangji Railway

With the development of China’s railway construction standards,the density and operation speed of train are also increasing,especially in the construction of railway passenger line,making the existing railway transport capacity being further liberation towards high-speed,heavy load direction.In order to improve the overall transport capacity of the railway to reduce transportation costs,should raise the level of China’s railway construction heavy-duty,heavy-duty rail transport development,increase the weight of the train,to "less input,multi-output" effect,in order to get the best economic benefits.Reload railroad operating in the process,the inertia force generated more common big trains,the rail under a lot of additional longitudinal force,when on the curve,due to the transverse horizontal component of the additional longitudinal force generated,plus big outer rail side wear and lateral squeeze the amount of rail,greatly increasing the chances of locomotives derailed,which also overloaded railway track maintenance and repair put forward higher requirements.In this paper,Zhangji rail project basis,at home and abroad on the basis of a detailed analysis of the static and dynamic track detection technology and repair system to repair the regulatory overview,from the aspects of heavy rail rail injury,disease roadbed,bridges and other diseases studied overloaded railway maintenance maintenance problems,combined with its long experience in track maintenance work through numerical analysis TQI Jining Public Works section lines,exploring the line due to repair and maintenance of status over the money from the management,provides a new way of thinking for the big machine maintenance.Mainly the following:1.System introduced abroad static and dynamic testing technology and heavy rail track repair system repair process overview,a comprehensive analysis of the existence of the Jining Public Works Maintenance line segment at this stage,pointing out that the current"check,raise,repair "under the system,track inspection car maintenance and repair of test data on line guidance.2.Summarized introduced five works of conservation management analysis tool.Regression analysis and probabilistic analysis of two analytical methods,explore TQI variation and related maintenance and repair management practices.3.In-depth analysis of Jining Public Works Section ancient Ying Pun line track inspection car workshop collecting data value from money management will TQI ancient camp were specific line shop,find the best point in time a large machine maintenance;explore owe line maintenance and over the maintenance of the status,the use of money management approach,the analysis of line for predictive maintenance approach,rational and efficient use TQI values to guide management of maintenance and repair work of the line.On line using a "Preventive Maintenance" approach,rational planning of maintenance and repair of the best time to ensure that the line is in equilibrium steady state.4.From the study of the rail damage,roadbed diseases,bridges and other diseases introduced heavy haul railway prone to disease problems,and to work with their own experience,analysis of the corresponding solutions,so prevention issues,problems and timely solutions to ensure that the track structure and operational safety of the line.
