摘 要

有轨式巷道堆剁起重机是随着立体仓库的出现而发展起来的专用起重机，通常简称为堆剁机。堆剁机是立体仓库中最重要的起重运输设备，是代表立体仓库特征的标志。其主要用途是在高层货架仓库的巷道内沿轨道运行，将位于巷道口的货物存入货格，或是取出货格内的货物运送到巷道口，完成出入库作业。

20世纪70年代初期，我国开始研究采用巷道式堆剁机的立体仓库，不久便广泛应用于各行业和地区，有的已经形成系列化，据不完全统计，到目前已建成三百余座。随着现代工业生产的发展，有轨巷道堆垛起重机的技术也在不断提高和完善。世界主要工业国家都把着眼点放在开发性能可靠的新产品和采用高新技术上，更加注重实用性和安全性。如今，自动化立体仓库及堆垛机已成为企业生产管理不可获缺的重要组成部分。

本文从实际问题出发，以现有设备为依托，先确定出堆垛机的总体结构及各部分的结构草图，然后运用理论力学、材料力学、机械设计、制造技术等专业知识，并查阅相关设计手册，对其机械部分进行了详细的设计计算，包括：机架、行走机构、提升机构、载货台和货叉伸缩机构。设计过程中，以实现堆垛机的机械性能为目的，在满足其强度、刚度、运行稳定性等要求的前提下，综合考虑结构的合理性和所选材料的经济性，力求达到高质量、低成本。

Abstract

Track Tunnel-Stacker Crane is developed by a special crane with the emergence of three-dimensional warehouse, usually referred to as stacker crane. Stacker crane is the most important lifting and transportation equipment in a three-dimensional warehouse, and is one characteristic of three-dimensional warehouse. Its main use is orbit along the roadway in tunnel of high-rise warehouse, put the goods that be located at the mouth of the tunnel into the shelves, or take out goods and delivered to the tunnel mouth, complete the storage operations. 

At the early 70’s of 20th, China started to develop the three-dimensional warehouse with stacker crane, and soon have be widely used in various industries and regions，some have formed serialization. According to incomplete statistics, more than 300 warehouses have been completed now. With the development of modern industry, the technology of stacker crane is being improved. All the world's major industrial countries focus on the development of new products with reliable performance and the use of high-tech，and pay more attention to the practicality and safety. At present, automatic three-dimensional warehouse and stacker crane have become an important component of production management.

This paper starts from the practical problems, and bases on existing equipments. Firstly confirm the overall structure of stacker crane and the draft of parts of the structure. Then use Theoretical Mechanics, Material Mechanics, Machine Design and Manufacturing Technology, and according to relevant design manuals, elaborates on its machinery parts, including: Rack, Running Mechanism, Lifting Mechanism, Loading Stations and Telescopic Fork Mechanism. In the design process, considering the rationality of structure and the economy of the selected materials in order to achieve the mechanical properties of stacker and request of strength, stiffness, running stability, attempt to reach the aim of high-quality, low-cost.
