【摘要】：能源節(jié)約與環(huán)境保護(hù)作為當(dāng)今社會最關(guān)注的問題，對港口裝卸行業(yè)制約尤為突出。經(jīng)濟(jì)的飛速發(fā)展促使港口裝卸設(shè)備的必須朝著大型化、專業(yè)化、自動化的方向發(fā)展，傳統(tǒng)的卸船設(shè)備由于能耗高、環(huán)境污染大已經(jīng)不能適應(yīng)時(shí)代的要求，螺旋卸船機(jī)在此背景下被港口廣泛采用。它由于生產(chǎn)率及利用系數(shù)高，易于實(shí)現(xiàn)物料的自動化輸送，同時(shí)由于是封閉式輸送，對環(huán)境的污染小，所以螺旋卸船機(jī)的廣泛應(yīng)用對節(jié)能和環(huán)境保護(hù)都有重要意義。 螺旋卸船機(jī)的優(yōu)點(diǎn)明顯，但是其設(shè)計(jì)難度也顯而易見。螺旋卸船機(jī)由于結(jié)構(gòu)復(fù)雜，設(shè)計(jì)參數(shù)繁多且參數(shù)相關(guān)性程度高，導(dǎo)致方案在設(shè)計(jì)過程中被不斷修改，設(shè)計(jì)難度大大增加，傳統(tǒng)的方法面對如此復(fù)雜的設(shè)計(jì)環(huán)境顯得捉襟見肘。一方面是螺旋卸船機(jī)的大量需求，另外一方面則是螺旋卸船機(jī)的復(fù)雜設(shè)計(jì)計(jì)算，計(jì)算機(jī)技術(shù)的飛速發(fā)展帶來的參數(shù)化設(shè)計(jì)方法為解決此問題提供了契機(jī)。參數(shù)化設(shè)計(jì)方法采用參數(shù)驅(qū)動計(jì)算、尺寸約束模型的方式進(jìn)行產(chǎn)品設(shè)計(jì)，能夠快捷、方便的完成產(chǎn)品整個(gè)設(shè)計(jì)過程。 本文以新型研發(fā)的L型螺旋卸船機(jī)為例，詳細(xì)介紹了L型螺旋卸船機(jī)參數(shù)化設(shè)計(jì)系統(tǒng)的實(shí)現(xiàn)。文章闡述了課題研究背景、目的及與本課題相關(guān)的國內(nèi)外發(fā)展現(xiàn)狀，詳細(xì)介紹了新舊設(shè)計(jì)方法在螺旋卸船機(jī)設(shè)計(jì)上的應(yīng)用。文中針對L型螺旋卸船機(jī)的總體設(shè)計(jì)以及各機(jī)構(gòu)設(shè)計(jì)做了大量工作。在總體設(shè)計(jì)中對輸送系統(tǒng)的主尺寸進(jìn)行設(shè)計(jì)、對關(guān)鍵部件受力分析、對輪壓、抗傾覆穩(wěn)定性進(jìn)行計(jì)算校核。在機(jī)構(gòu)設(shè)計(jì)中對水平螺旋部分、垂直螺旋部分、俯仰平衡系統(tǒng)、回轉(zhuǎn)機(jī)構(gòu)、運(yùn)行機(jī)構(gòu)的關(guān)鍵性能及選型參數(shù)的進(jìn)行設(shè)計(jì)計(jì)算。在系統(tǒng)設(shè)計(jì)工作中，詳細(xì)的闡述了系統(tǒng)的設(shè)計(jì)思想及工作流程，介紹了系統(tǒng)的主界面及子窗口的組成及運(yùn)行原理，對編程中的過程代碼的都做出了明確的說明，在上述任務(wù)完成的基礎(chǔ)上開發(fā)出L型螺旋卸船機(jī)參數(shù)化設(shè)計(jì)系統(tǒng)。 本課題開發(fā)的L型螺旋卸船機(jī)參數(shù)化設(shè)計(jì)系統(tǒng)界面美觀，操作方便，能夠快速的用于L型螺旋卸船機(jī)設(shè)計(jì)，，系統(tǒng)在設(shè)計(jì)過程中運(yùn)行穩(wěn)定，通過與已完成的設(shè)計(jì)數(shù)據(jù)對比，系統(tǒng)設(shè)計(jì)數(shù)據(jù)準(zhǔn)確。本系統(tǒng)不僅降低了L型螺旋卸船機(jī)的設(shè)計(jì)難度，同時(shí)提高了設(shè)計(jì)效率，具有很大的實(shí)用性。
[Abstract]:Energy conservation and environmental protection, as the most concerned issues in the society today, are particularly important to the port loading and unloading industry.With the rapid development of economy, the port loading and unloading equipment must develop towards the direction of large scale, specialization and automation. Because of the high energy consumption, the environmental pollution has not been able to meet the requirements of the times.Helical ship unloader is widely used in port under this background.Because of its high productivity and utilization coefficient, it is easy to realize the automatic transportation of materials, and because of the closed conveying, the pollution to the environment is small, so the wide application of screw ship unloader is of great significance to energy saving and environmental protection.The advantages of spiral ship unloader are obvious, but its design difficulty is also obvious.On the one hand, there is a lot of demand for screw ship unloader, and on the other hand, the complex design calculation of screw ship unloader. The parametric design method brought by the rapid development of computer technology provides an opportunity to solve this problem.The parameterized design method adopts parameter-driven calculation and dimension constraint model to design the product, which can finish the whole design process quickly and conveniently.Taking the new developed L type screw ship unloader as an example, the realization of the parameter design system of L type screw ship unloader is introduced in detail in this paper.This paper expounds the research background, purpose and the development status of this subject at home and abroad, and introduces in detail the application of the new and old design methods in the design of screw ship unloader.In this paper, a great deal of work has been done on the overall design of L-type screw ship unloader and the design of each mechanism.In the overall design, the main dimensions of the conveying system are designed, the stress of the key components is analyzed, the wheel pressure and the stability against overturning are calculated and checked.In the design of the mechanism, the key performances of the horizontal screw, the vertical screw, the pitching balance system, the rotary mechanism and the operating mechanism are designed and calculated.In the design work of the system, the design idea and work flow of the system are elaborated in detail, the composition and operation principle of the main interface and sub-window of the system are introduced, and the process code in the programming is clearly explained.On the basis of the above tasks, a parameterized design system for L type screw ship unloader is developed.The system design data is accurate.This system not only reduces the design difficulty of L type screw ship unloader, but also improves the design efficiency.
