摘 要

本文主要是有轨堆垛机的机械部分设计，包含堆垛机的行走机构、升降机构、伸缩机构的设计，其中重点放在了行走机构的设计上。根据比较选择了单立柱堆垛机，在进行机构的设计时，根据电机确定机构的总体结构，再由运行阻力计算行走电机的功率，进而确定电机型号。本设计升降轨道采用双柱型轨道，结构简单工艺性好，货叉伸缩机构借鉴了抽屉轨道的原理。根据设计要求对各主要部件初步选型后再对部件进行强度的校核，来保证选择的合理性。在本文最后部分，对该堆垛机的刚性和稳定性进行了较为详细的分析，从而保证了堆垛机工作时运行的平稳性和可靠性。 关键词：有轨堆垛机，行走机构，双柱型轨道

Abstract

This paper describes the design of the mechanical structure , including the walking、lifting、stretch outing and draw backing mechanism of a stacker crane, in my design work I focus on the design of the walking mechanisms. According to the comparison we choice the single pillar stacker , In the design of the mechanism ,we according to he motor institutions determine the general structure of a stacker crane, Then cording the resistance to calculation traveling motor power and determine the motor model. Tracking the movement double column type orbit. Structure is simple and good in usability. The goods for the expansion institutions fork drawer the principle of orbit. According to the design requirements of the main components of preliminary selection, then to parts of checking intensity. to ensure that the choice of rationality . In the last part of this paper , the stacker strength and stability for a more detailed analysis , so as to ensure the smoothness of work stacker slide may run and reliability .

Keywords: stacker crane, walking mechanism, double column type orbit
