【摘要】：隨著經(jīng)濟(jì)的發(fā)展和時(shí)代的進(jìn)步,社會(huì)分工越來(lái)越明確和細(xì)化。工程設(shè)備越來(lái)越大,運(yùn)輸要求也越來(lái)越高,海上貨物運(yùn)輸日漸也呈現(xiàn)出專(zhuān)業(yè)化、科技化、多樣化的趨勢(shì)。大型工程設(shè)備像船閘、游艇、核電蒸發(fā)器、橋墩等等,體積、重量逐漸增大。傳統(tǒng)的雜貨船已經(jīng)跟不上時(shí)代的腳步,漸漸不適應(yīng)運(yùn)輸這類(lèi)重大件貨物,需要使用現(xiàn)代化專(zhuān)業(yè)的重大件運(yùn)輸船舶來(lái)代替。大多港口岸吊裝卸能力有限,自然而然也就滿(mǎn)足不了類(lèi)似上述貨物的裝卸要求,因此船舶配備重吊是一種趨勢(shì),本文主要研究重吊船裝卸超長(zhǎng)、超重件方案設(shè)計(jì)研究。船舶裝卸重大件時(shí),船舶吃水、吃水差、橫傾角、穩(wěn)性等參數(shù)會(huì)產(chǎn)生相應(yīng)的變化。貨物質(zhì)量越大,對(duì)船舶的影響越大,船舶參數(shù)變化也就越大,因貨物和船舶的價(jià)值十分高昂,保證貨物安全裝卸和運(yùn)輸至關(guān)重要。傳統(tǒng)的人工計(jì)算,程序繁瑣,操作過(guò)程中還需要進(jìn)行壓載水的配合,這就使得工作人員操作時(shí)顧此失彼、工作緊張。無(wú)法提前預(yù)知操作過(guò)程中的未知風(fēng)險(xiǎn),容易造成船舶及貨物的損壞,進(jìn)而給船東和貨主造成巨大財(cái)產(chǎn)損失。要想減輕工作量,保證大件運(yùn)輸安全,船公司及貨主應(yīng)提前做好裝卸和運(yùn)輸計(jì)劃,以保證船舶裝卸重大件期間的安全操作,也急需將計(jì)算機(jī)技術(shù)投入到船舶裝卸和運(yùn)輸重大件工作中。首先,本文在對(duì)重大件貨物、重大件貨物運(yùn)輸船舶等相關(guān)概念、分類(lèi)和特點(diǎn)進(jìn)行概述與總結(jié),突出研究探討了重吊船運(yùn)輸和裝卸重大件的方案的編制。其次,重點(diǎn)推導(dǎo)重吊船雙機(jī)聯(lián)吊超長(zhǎng)、超重貨物穩(wěn)性和橫傾角計(jì)算公式。然后分析了雙機(jī)聯(lián)吊時(shí)貨物受力,把聯(lián)吊過(guò)程分解成兩吊同時(shí)各自吊貨物,并對(duì)雙吊的水平角協(xié)調(diào)關(guān)系進(jìn)行推導(dǎo)和解算。再次,基于VB 6.0程序設(shè)計(jì)軟件和Auto CAD畫(huà)圖軟件。設(shè)計(jì)了模擬船舶雙機(jī)聯(lián)吊在裝卸重大件過(guò)程,并設(shè)計(jì)輔助計(jì)算程序,最終實(shí)現(xiàn)船舶裝卸計(jì)算簡(jiǎn)化。最后,對(duì)未來(lái)重吊船全自動(dòng)聯(lián)吊和三維智能、動(dòng)態(tài)重吊配載儀的設(shè)計(jì)提出構(gòu)想。
[Abstract]:With the development of economy and the progress of the times, the social division of labor becomes more and more clear and detailed.The engineering equipment is getting bigger and bigger, the transportation request is higher and higher, the sea cargo transportation also presents the specialization, the science and technology, the diversification trend day by day.Large-scale engineering equipment such as locks, yachts, nuclear evaporators, piers and so on, volume, weight gradually increased.The traditional general cargo ship has been unable to keep pace with the times, and gradually can not adapt to the transport of this kind of major goods, need to use modern professional transport ship to replace it.The loading and unloading capacity of most port ports is limited, so the loading and unloading requirements of the above mentioned cargo can not be satisfied naturally, so it is a trend for ships to be equipped with heavy hoisting. This paper mainly studies the design of overlong loading and unloading of heavy lifting vessels and overweight parts.The parameters such as draught, draught difference, inclination angle and stability will change when loading and unloading heavy parts.The greater the cargo quality, the greater the impact on the ship, and the greater the change of ship parameters. Because the value of cargo and ship is very high, it is very important to ensure the safe loading and unloading and transportation of cargo.The traditional manual calculation, the procedure is tedious, the operation process also needs to carry on the ballast water cooperation, this causes the staff operation to ignore one another, the work is tense.The unknown risk in the course of operation can not be predicted in advance, which can easily cause damage to ship and cargo, and then cause huge property loss to shipowners and shippers.In order to reduce the workload and ensure the safety of large cargo transportation, shipping companies and cargo owners should make good handling and transportation plans in advance in order to ensure the safe operation during the loading and unloading period of ships.It is also urgent to apply computer technology to ship handling and transportation.First of all, this paper summarizes and summarizes the related concepts, classification and characteristics of heavy cargo and major cargo transport vessels, and studies and discusses the compilation of the scheme of heavy lifting ship transportation and loading and unloading.Secondly, the formulas for calculating the stability and heeling angle of the heavy lifting ship with double crane are derived.Then the paper analyzes the loading force of the cargo when the double hoisting machine is connected, and decomposes the process of the joint hoisting into two hoists and each of them simultaneously, and deduces and calculates the horizontal angle coordination relation of the double hoists.Again, based on VB 6.0 program design software and Auto CAD drawing software.The process of simulating the loading and unloading of heavy parts by double crane is designed, and the program of auxiliary calculation is designed to simplify the calculation of ship loading and unloading.Finally, the design of the automatic hoisting and three-dimensional intelligent and dynamic crane stowage for the future heavy lifting platform is put forward.
