摘要
随着科技的发展，港口技术日益精进，目前港口和港口机械都向着智能化、标准化、大型化、多式联运和节能环保 等方向发展，对于港口机械结构的强度刚度和稳定性也有了更高的要求。对于港口起重机的外形尺寸很大，工的情况十分严酷，启动和制动的频率大，并且启动制动造成的冲击载荷大，这些情况。对于装卸集装箱，我们有定位精确，高速度高效率的要求。这些都要依赖设计刚性良好的钢结构和现代电控系统，并且需要严格的设计来保证。
装船机作为装卸货物的极其重要的港口机械，在物流运输的过程中起了很大的作用。本着港口机械装卸更有效率，更环保的角度出发设计出了港口所需的效率为7500t/h装船机。本文从装船机的结构尺寸及风力距、轮压等方面进行了总体设计；并对该装船机的俯仰机构进行了设计。
利用设计的总体尺寸及俯仰机构的设计尺寸进行画图；生成CAD的图纸。
关键词：装船机，风力距，轮压，俯仰系统，总体设计，俯仰系统，CAD
Abstract
With the development of science and technology, port technology is increasingly sophisticated. At present, ports and port machinery are developing in the direction of intelligence, standardization, large-scale, multimodal transport, and energy conservation and environmental protection. The strength and stability of port mechanical structures are also higher. The request. For port cranes, the dimensions of the crane are very large, the condition of the work is very severe, the frequency of starting and braking is large, and the impact load caused by the starting brake is large. For loading and unloading containers, we have precise positioning, high speed and high efficiency requirements. All these depend on the design of steel structures with good rigidity and modern electronic control systems, and they need to be strictly designed to ensure. [资料来源：http://doc163.com]
As an extremely important port machinery for loading and unloading goods, the ship loading machine plays a very important role in the process of logistics and transportation. Based on a more efficient and environmentally friendly port loading and unloading operation, the port has designed an efficiency of 7500 t/h for ship loading. In this paper, the overall design of the ship's structure size, wind distance and wheel pressure is carried out. The pitching mechanism of the ship loader is designed.
Use the overall dimensions of the design and the design dimensions of the pitch mechanism to draw; generate CAD drawings.
Key words:Ship loader, wind distance, wheel pressure, pitch system, overall design, pitch system, CAD
