适应货运改革的铁路编组站设备配置研究
发布时间：2018-11-20 14:04
【摘要】：随着我国高速铁路陆续建成通车,铁路货运能力得到了释放,为铁路部门根据市场需求优化运输组织创造了条件。自2012年9月20日起,铁路部门开展了 "实货制"运输组织方式,依托货运电子商务系统,简化了货主办理托运的手续,节约了运输时间,同时也提高了铁路部门自身的工作效率,使铁路的物流服务得到了进一步的拓展。编组站作为铁路系统中最重要的子系统之一,其对货运改革的适应性决定了货物运输质量。本文首先介绍了我国铁路编组站的分类及分布,分析了目前全国编组站的运输组织和设备配置现状,阐述了在货运组织改革的趋势下,编组站通过能力、改编能力在运量下滑情况下基本适应货物运输需求。接着,从货物运输改革的内容、对货流的影响和对车流的影响三方面入手,分析了货物运输改革的特点,总结货物运输改革后铁路推出的新运输产品,介绍快运货物列车及其时效性要求。通过定性分析快货列车在编组站内的运输组织需求,得知快货车组由于有18小时时限,其在到达、解体和编组作业过程中有一定的优先权。因此,编组站需改变以往以大组车流为核心的组织方式,改为以快货车组为核心进行运输组织。定量计算了编组站到发线、调车机车、驼峰和调车线等设备因货运改革而产生的额外作业所导致的空费能力。以到发线为研究对象,提出快货车组到达组合的概念,给出四种列车到达组合。基于排队论的思想,结合最小间隔法计算四种组合的最小列车到达间隔,求出到达场的平均列车最小达到间隔,得到了到发线通过能力,进一步算得到发线因为货改而产生的空费。最后以成都北编组站作为实例,分析其适应货改的编组站设备运用情况。
[Abstract]:With the completion and opening of high-speed railway in China, railway freight capacity has been released, which creates conditions for railway departments to optimize transportation organization according to market demand. Since September 20, 2012, the railway department has launched the "real cargo system" transportation organization mode, relying on the freight electronic commerce system, which simplifies the procedures for consignments by cargo owners and saves transportation time. At the same time, it also improves the working efficiency of railway department itself, and makes the logistics service of railway get further expansion. As one of the most important subsystems in railway system, the adaptability of marshalling yard to freight transport quality determines the quality of freight transportation. This paper first introduces the classification and distribution of railway marshalling yards in China, analyzes the present situation of transportation organization and equipment allocation of marshalling yards in China, and expounds the passing capacity of marshalling yards under the trend of freight transportation organization reform. Adaptation capacity in the case of declining capacity to adapt to the basic freight transport demand. Then, starting with the content of the freight transport reform, the impact on the freight flow and the impact on the vehicle flow, the characteristics of the freight transport reform are analyzed, and the new transport products introduced by the railway after the freight transport reform are summarized. This paper introduces the express freight train and its timeliness requirements. Through the qualitative analysis of the transportation organization demand of the express freight train in the marshalling yard, it is found that the fast freight train has certain priority in the process of arrival, disintegration and marshalling because of the 18 hour time limit. Therefore, the marshalling yard needs to change the former organization mode with large group traffic as the core, and change to take the fast freight train group as the core to carry on the transportation organization. The capacity of extra work caused by freight reform for the equipment of marshalling station to departure line, shunting locomotive, hump and shunting line is calculated quantitatively. Taking the arrival and departure line as the research object, this paper puts forward the concept of fast train group arrival combination, and gives four kinds of train arrival combination. Based on the thought of queuing theory and the method of minimum interval, the minimum arrival interval of four kinds of combined trains is calculated, and the average minimum train arrival interval of arrival field is obtained, and the transit capacity of arrival and departure line is obtained. Further calculation of the shipping line due to the cargo change caused by the cost of space. Finally, taking Chengdu North marshalling Station as an example, the application of the equipment adapted to cargo reform is analyzed.
