可移动式升降台设计毕业设计(前言摘要)

摘要

升降台主要应用于物流过程中高度差之间的货物输送、传递等，如与流水线、专用设备等配套使用；货物装卸；大型设备举升等,不同的工况要求可选择不同的台面形式（如:滚轴、滚珠、转盘等）。产品承载量大、行程范围广、安全高效，是现代工业提高工效之必备。

可移动式液压升降台是在原升降台的工作基础之上,将移动装置与升降台配合使用，摆脱了过去升降台固定不动的模式，使升降台实现货物或原料的快速装卸,不仅提高了升降台的工作效率，同时可以使升降台不再受工作场地的限制,扩大了升降台的使用范围。同时在控制系统上使用电气控制，用简单的接触器、开关等,控制升降台的起动、停止、上升、下降等工作步骤，方便,快捷，大大的节省了人力,提高了生产效率,因此在工厂等生产单位得到了广泛的应用。

在本设计中，分别从升降台，移动装置，控制装置三个方面着手研究。升降台的设计部分，着重对升降台的机构分析，机构设计，液压缸的选择以及各重要部件的强度进行了详细的计算和准确的校核；移动装置部分，主要是对装置的的传动设计的选择以及传动件的强度与刚度进行了深入的分析;控制部分则主要对控制系统的原理进行了详细的阐述。

通过以上的设计研究,可以确保产品各部件能够安全稳定的工作，各部分装置之间能够协调配合，以满足可移动式液压升降台的工作需要。

Abstract

Lifting table mostly appltes to the transportation and transfer of goods when there is difference in degree in goods flow process and so on。 For instance， to assort

with pipeline and specialized facility,To load and unload goods,To lift major equipment. Different working condition requires different flats form（for instance:Rolling shaft， bearing ball， turnplate and more）.The bearing capacity of this product is large， journey scope is expand and safety is height render.All of these are necessary when modern industry want to improve work efficiency。

Removable hydraulic pressure lifting table lifting table should use mixing shifter and lifting table basic on original lifting table. It gets rid of sedentary mode of past lifting table and makes quick dispatch of goods or raw material be true.It not only improves efficiency of lifting table’work，but also could get rid of the limit of working space of lifting table and enlarge the range of use of lifting table。At the same time,if uses electric control in control system with simple contactor，switch and more,it could control the start, stop, upgrade and decline of lifting table. All of these are convenience,immediacy and can economize human power, improve production efficiency. Wherefore,it comes into widely application in production of industry。

In this paper，I test from lifting table ，shifter and monitor three aspects。 In the part of lifting table'desinging,this paper will analyses institution of lifting table, institute on desinging， selection of hydraulic cylinder as well as detailed counts intensity of each important nodal and checks. In the part of shifter， this paper primarily designs transfer motion and intensity of driving medium as well as analyses rigidity。 Control section detailed expounds the theory of control system.

Through foregoing design studies, it could ensure each assembly that be able to operate stably， timing between each several part device in terms of satisfacting the demand of hydraulic pressure lifting table’work。
