【摘要】：港口作為水陸交通的重要樞紐,對(duì)我國(guó)經(jīng)濟(jì)建設(shè)起到了非常重要的作用。我國(guó)港口噸位規(guī)模不斷擴(kuò)大,貨物年吞吐量屢創(chuàng)新高,隨之而來(lái)的是能源的巨大浪費(fèi)和環(huán)境污染的不斷惡化。同時(shí)隨著港口間的競(jìng)爭(zhēng)加劇,進(jìn)口散貨碼頭向著大型化、多用途化、節(jié)能化的方向發(fā)展,然而目前很多專業(yè)化散貨碼頭的作業(yè)貨物種類單一,影響了港口經(jīng)濟(jì)的發(fā)展。因此,面對(duì)復(fù)雜的港口情況需要制定出一套系統(tǒng)的解決方案。本文通過(guò)結(jié)合港口裝卸設(shè)備、裝卸工藝和散貨物料的輸送路徑,以節(jié)能為目的并考慮多種因素,對(duì)進(jìn)口散貨碼頭的裝卸設(shè)備進(jìn)行選型,對(duì)碼頭的輸送系統(tǒng)進(jìn)行路徑規(guī)劃,采用減電機(jī)技術(shù)對(duì)堆場(chǎng)皮帶機(jī)進(jìn)行改造,達(dá)到港口節(jié)能的目的。首先,本文研究了進(jìn)口散貨碼頭卸船、運(yùn)輸和儲(chǔ)存作業(yè)的現(xiàn)狀和發(fā)展趨勢(shì)。目前進(jìn)口散貨碼頭朝著大型化、多功能化和節(jié)能化的方向發(fā)展,這就要求散貨碼頭能夠適應(yīng)不同的來(lái)港船型,可以接卸不同種類的散貨物料,并能夠盡量減少能源的浪費(fèi),降低成本,從而增強(qiáng)碼頭的競(jìng)爭(zhēng)能力。其次,大型散貨碼頭的裝卸設(shè)備、工藝和輸送系統(tǒng)影響著碼頭的能源消耗,文章采用層次分析法對(duì)卸船機(jī)進(jìn)行選型設(shè)計(jì),根據(jù)堆場(chǎng)作業(yè)情況選擇堆、取料設(shè)備。依據(jù)來(lái)港船型、貨物種類等因素,對(duì)皮帶機(jī)系統(tǒng)的輸送路徑進(jìn)行規(guī)劃設(shè)計(jì),并采用減電機(jī)技術(shù)對(duì)堆場(chǎng)皮帶機(jī)進(jìn)行改造。最后,本文以防城港20萬(wàn)噸礦石碼頭為例,采用層析分析法選擇橋式抓斗卸船機(jī)進(jìn)行卸船作業(yè),采用斗輪堆取料機(jī)進(jìn)行堆場(chǎng)作業(yè),對(duì)碼頭的輸送路徑進(jìn)行規(guī)劃,從而使得煤炭和礦石運(yùn)輸采用不同的輸送路徑,最后根據(jù)堆場(chǎng)皮帶機(jī)的4種作業(yè)工況使用減電機(jī)節(jié)能技術(shù),并用VC++6.0開(kāi)發(fā)出專門的減電機(jī)計(jì)算軟件。
[Abstract]:As an important hub of land and water transportation, port plays a very important role in the economic construction of our country. The tonnage of ports in our country is expanding and the annual throughput of cargo is reaching a new high. The huge waste of energy and the worsening of environmental pollution come with it. At the same time, with the intensification of competition between ports, the import bulk wharf is developing towards the direction of large-scale, multi-purpose and energy-saving. However, at present, many specialized bulk wharves have a single type of operating cargo, which has affected the development of port economy. Therefore, in the face of complex port situation, we need to work out a set of systematic solutions. In this paper, combined with port loading and unloading equipment, loading and unloading technology and transportation path of bulk materials, taking energy saving as the purpose and considering various factors, the paper chooses the loading and unloading equipment of import bulk cargo terminal, and plans the route of the terminal transportation system. The technology of subtraction motor is used to transform the belt conveyor in the yard to achieve the purpose of energy saving in port. Firstly, this paper studies the present situation and development trend of the loading, unloading, transportation and storage operations of the import bulk cargo wharf. At present, the import bulk cargo wharf is developing towards the direction of large-scale, multi-functional and energy-saving. This requires that the bulk cargo terminal can adapt to different types of incoming ships, be able to unload different kinds of bulk cargo materials, and reduce the waste of energy as much as possible. Reduce the cost, thereby enhancing the competitiveness of the wharf. Secondly, the loading and unloading equipment, technology and transportation system of large bulk cargo wharf affect the energy consumption of wharf. In this paper, the type selection design of ship unloader is carried out by AHP, and according to the working conditions of the yard, the reactor and material collection equipment are selected. According to the factors of ship type and cargo type, the conveyance path of belt conveyor system is planned and designed, and the belt conveyor in the yard is modified by subtraction motor technology. Finally, taking the 200000 ton ore wharf of Fangcheng Port as an example, the paper chooses bridge grab ship unloader to unload ship by using chromatography analysis, and uses bucket wheel stacker to carry out yard operation, and plans the transportation route of wharf. In order to make coal and ore transportation adopt different transportation routes, according to the four working conditions of the yard belt machine, the energy saving technology of subtraction motor is used, and a special calculation software of subtraction motor is developed with VC 6.0.
