Analysis On Heavy Haul Transportation Unloading Organization For DA-Qin Line

In recent years, China's national economic and social maintained sustained, rapid developm-ent, which drove the rapid growth of energy demand,. Especially, the requirement of coal will rise with steady steps, railroad transportation demand will be higher. While our technology for railway heavy-load transportation is behindhand, it must be very important for improving efficie-ncy of railway transportation to study heavy haul railroad transportation mode with improving efficiency of unloading.Da-Qin railway as China's first modernization first heavy-duty coal line and important channel for "Western coal shipped East", freight volume increases annually by 5 thousand tons, freight volume reached 1.034 million tons in 2002, and completed 3.5 million tons in 2008, it had made great contribution to our national's sustained rapid growth of economic.So the rail ministry advanced that the transport capacity of the Da-Qin railway will improve to 400 million ton. The organize principle of the railway is "first unload, second eject, and then load", On the transportation, unloading is the important node, and the trustiness assure of complete loading and ejecting. So, it must be done well for the unloading arrangement, improving the efficiency of unloading.The paper first introduced that the transportation composing of Da-Qin 400 million, the rebuilding work on the loading place, the improving of engine and vehicle, and the fetching of the advanced communicate technique. And introduced that how to combine the train of 10 thousand and 20 thousand, and the using mode of engine. It say that the Da-Qin railway can transport 400 million. And then the peculiarity of unloading and the effect of unloading were analyzed and summarized.The paper put forward the way that can solve the effect from the points of the unloading equipment and the unloading arrangement on the unloading place. We choose the fit equipment that can unload great movement efficiently by analyzing the stage, the unloading equipment and the rain flow. The paper introduced and analyzed the using model of the engine and the unite working of railway and port at the principle that load and unload the whole line, come and back straightly, and dispel solid. At the same time, the paper analyzed the model of answering the problem that the flow arrived imbalance, the construction task is heavy, the port is sluggish and scatter. And the paper analyzed the enjoy of the information between railway and port, and advanced the system of checking on the unloading station. All that we do affected importantly on the unloading for the Da-Qin railway.
