【摘要】：能源节约与环境保护作为当今社会最关注的问题，对港口装卸行业制约尤为突出。经济的飞速发展促使港口装卸设备的必须朝着大型化、专业化、自动化的方向发展，传统的卸船设备由于能耗高、环境污染大已经不能适应时代的要求，螺旋卸船机在此背景下被港口广泛采用。它由于生产率及利用系数高，易于实现物料的自动化输送，同时由于是封闭式输送，对环境的污染小，所以螺旋卸船机的广泛应用对节能和环境保护都有重要意义。螺旋卸船机的优点明显，但是其设计难度也显而易见。螺旋卸船机由于结构复杂，设计参数繁多且参数相关性程度高，导致方案在设计过程中被不断修改，设计难度大大增加，传统的方法面对如此复杂的设计环境显得捉襟见肘。一方面是螺旋卸船机的大量需求，另外一方面则是螺旋卸船机的复杂设计计算，计算机技术的飞速发展带来的参数化设计方法为解决此问题提供了契机。参数化设计方法采用参数驱动计算、尺寸约束模型的方式进行产品设计，能够快捷、方便的完成产品整个设计过程。本文以新型研发的L型螺旋卸船机为例，详细介绍了L型螺旋卸船机参数化设计系统的实现。文章阐述了课题研究背景、目的及与本课题相关的国内外发展现状，详细介绍了新旧设计方法在螺旋卸船机设计上的应用。文中针对L型螺旋卸船机的总体设计以及各机构设计做了大量工作。在总体设计中对输送系统的主尺寸进行设计、对关键部件受力分析、对轮压、抗倾覆稳定性进行计算校核。在机构设计中对水平螺旋部分、垂直螺旋部分、俯仰平衡系统、回转机构、运行机构的关键性能及选型参数的进行设计计算。在系统设计工作中，详细的阐述了系统的设计思想及工作流程，介绍了系统的主界面及子窗口的组成及运行原理，对编程中的过程代码的都做出了明确的说明，在上述任务完成的基础上开发出L型螺旋卸船机参数化设计系统。本课题开发的L型螺旋卸船机参数化设计系统界面美观，操作方便，能够快速的用于L型螺旋卸船机设计，，系统在设计过程中运行稳定，通过与已完成的设计数据对比，系统设计数据准确。本系统不仅降低了L型螺旋卸船机的设计难度，同时提高了设计效率，具有很大的实用性。
[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.
