摘 要
随着我国国民经济的快速发展,人类的生产生活方式趋于集中,城市的规模逐渐变大,人在城市里的生存空间却越来越小,仓储物流的立体化集中化就变的越发重要。立体仓库为现代的物流系统重要部分之一,是多层的存放货物的高架仓库,主要由:控制与管理系统、物流升降平台、计算机管理控制系统、高位货架、出入库以及其他得辅助设备组成。
其中重点研究的是基于立体仓库的物流升降平台的设计与使用。文章设计了立体仓库的物流升降平台的支撑结构并校核通过。设计了物流升降平台中液压系统的横向移动、纵向推送和提升运动的系统,并计算选取了相应的液压系统和元件。画出了液压系统的原理图,液压站示意图,液压缸图与整体示意图。其中物流升降平台的货架是可以堆叠增加层数的,由钢结构组成,增加了仓储容量的可调性。而货物从入货口由传送带送入仓库,也可由传送从仓库送到出货口,实现货存取方便性提高。
关键词:立体仓库。结构设计。液压升降平台。物流。
ABSTRACT
With the rapid development of China's national economy, human production and lifestyle tend to focus on the scale of the city gradually become larger, people in the city's living space is getting smaller and smaller, three-dimensional storage of logistics become more important The Three-dimensional warehouse is an important part of modern logistics system, is a multi-storey storage of goods warehouse system, by the control and management system, high shelves, logistics platform, warehousing, storage, computer management and control systems and other auxiliary equipment composition.
Which focuses on the study is based on the three-dimensional warehouse logistics platform design and use. This paper designs the support structure of the logistics platform of the three-dimensional warehouse and checks and passes it. The system of lateral movement, longitudinal pushing and lifting movement of the hydraulic system in the platform is designed and the corresponding hydraulic system and components are calculated. The hydraulic system schematic diagram, hydraulic cylinder diagram, hydraulic station map and tank welding map. Which is the platform of the logistics platform can be stacked to increase the number of layers, composed of steel structure, increasing the storage capacity of the adjustable; and the goods from the mouth into the warehouse by the conveyor belt can also be sent from the warehouse to the export port .To achieve the convenience of cargo access to improve.
KEY WORDS: three-dimensional warehouse; structural design;
hydraulic lifting platform; logistic

1.1本课题研究的内容与意义
课题研究的内容为:立体仓库整体结构的设计、钢结构框架的选型计算、液压升降平台的设计、结构强度的校核以及液压系统与液压站的设计。并绘制出了零件图纸和装配图。
本课题研究的意义是: 随着我国国民经济的快速发展,人类的生产生活方式趋于集中,城市的规模逐渐变大,人在城市里的生存空间却越来越小,仓储物流的立体化集中化就变的越发重要。立体仓库为现代的物流系统重要部分之一。且立体仓库是我国的新兴产品。他具有广阔发展前景。该设备是现代物流的重要组成部分,可以充分的利用原有空间。(具有降低储运损耗、减少流动资金的积压、消除差错、提高仓储管理水平、减轻劳动的强度、提高操作人员的素质、提高物流效率等优点)[1]。
而立体仓库的液压升降平台是一种升降性能好,适用范围广的货物举升机构,可用于生产流水线中有高度差的设备之间的货物运送,物料上线,下线,大型机库上料,下料等场所,可以与叉车等工作设备配套使用。它用液压系统控制,采用液压系统有如下特点:
