The Up Marshalling Design Of The Xinfengzhen Automatic Hump Yard

Marshalling stations are generally located in a large number of freight trains and the disintegration of the distribution center and the railway intersection point.The port and large enterprises with railway operations generally have a marshalling station in front of port and in line with the enterprise.The marshalling station is equipped with the locomotive depot and depot,for pick up the car to start the starting line for line(or both at the start line and line function to the hair line),and for a large number of goods train disintegration,assembly and marshalling operation for shunting line(also known as marshalling line),is used for shunting locomotive pull disintegration and marshalling for traction line and hump etc.The yard head line to a certain height,let the vehicle in its weight and the line height by rolling into a predetermined shunting line,the disintegration of shunting device is used hump train.Hump plays an important function in the whole railway transportation,and it is also an important characteristic of the marshalling station,which is a powerful guarantee for the efficient current freight car.In the optimization of the adaptation ability of the marshalling station,the disintegration and the formation are the main abilities of the modern hump.In order to meet the needs of modern large cargo capacity of the hump,in order to cope with the current increase in freight volume and the optimization of its capacity to strengthen the organization.Zhengzhou is our country in the heart of railway transport,freight volume increased year by year,making the region to implement measures to relieve.The Xinfengzhen station,located in the west of our country,is established in the area of the hump yard,which not only effectively relieve the pressure of transport in Zhengzhou,but also maintain the balance of the passenger volume in the eastern and western regions.Xi’an hub,the Xinfengzhen station is a large marshalling station,this station will usher in the future should adapt to changes in the traffic flow and the increase in the amount of freight,the efficiency of the hump can not meet the requirements of the disintegration.So it is necessary to consider the separation of the uplink and downlink system,which is based on the original foundation to build up the uplink system which is in line with the expected formation.This paper is to optimize the design of the uplink hump.Optimization design of the Xinfengzhen hump plane,according to the arrangement of the original wire harness,switch selection is analyzed,and the distribution curve,determined the number of hump marshalling yard,related to the line shunting line length,line number and the rolling line beam layout,to find out the suitable and effective type of switch curve layout.Longitudinal section design of hump.The operation for basic resistance,humping existing switch resistance,wind resistance and resistance of the corresponding curve,determine the relevant hump height value,thereby completing the basic design of the vertical section of the hump related,and the reference peak will optimize the analysis of its high profile to.Operation with high braking energy.First calculate the speed of the reducer area in the import and export situation,which can be high,the period to do a good job in the scientific distribution of the braking position.The optimization design of the advantage and disadvantage of running environment by this paper,calculation of rolling cut time and speed of the curve,the difficulty of rolling driving time interval test operation.The design of the program,the need to refer to the actual situation of the construction site to do a real timely correction,in accordance with the actual situation in order to achieve more reasonable.According to the actual inspection and analysis,this design is scientific and reasonable in the design of the Xinfengzhen hump.
