【摘要】：随着经济的发展和时代的进步,社会分工越来越明确和细化。工程设备越来越大,运输要求也越来越高,海上货物运输日渐也呈现出专业化、科技化、多样化的趋势。大型工程设备像船闸、游艇、核电蒸发器、桥墩等等,体积、重量逐渐增大。传统的杂货船已经跟不上时代的脚步,渐渐不适应运输这类重大件货物,需要使用现代化专业的重大件运输船舶来代替。大多港口岸吊装卸能力有限,自然而然也就满足不了类似上述货物的装卸要求,因此船舶配备重吊是一种趋势,本文主要研究重吊船装卸超长、超重件方案设计研究。船舶装卸重大件时,船舶吃水、吃水差、横倾角、稳性等参数会产生相应的变化。货物质量越大,对船舶的影响越大,船舶参数变化也就越大,因货物和船舶的价值十分高昂,保证货物安全装卸和运输至关重要。传统的人工计算,程序繁琐,操作过程中还需要进行压载水的配合,这就使得工作人员操作时顾此失彼、工作紧张。无法提前预知操作过程中的未知风险,容易造成船舶及货物的损坏,进而给船东和货主造成巨大财产损失。要想减轻工作量,保证大件运输安全,船公司及货主应提前做好装卸和运输计划,以保证船舶装卸重大件期间的安全操作,也急需将计算机技术投入到船舶装卸和运输重大件工作中。首先,本文在对重大件货物、重大件货物运输船舶等相关概念、分类和特点进行概述与总结,突出研究探讨了重吊船运输和装卸重大件的方案的编制。其次,重点推导重吊船双机联吊超长、超重货物稳性和横倾角计算公式。然后分析了双机联吊时货物受力,把联吊过程分解成两吊同时各自吊货物,并对双吊的水平角协调关系进行推导和解算。再次,基于VB 6.0程序设计软件和Auto CAD画图软件。设计了模拟船舶双机联吊在装卸重大件过程,并设计辅助计算程序,最终实现船舶装卸计算简化。最后,对未来重吊船全自动联吊和三维智能、动态重吊配载仪的设计提出构想。
[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.
