单体液压支柱 毕业设计.doc

摘要
本论文所设计的是适用于大倾角煤层使用的单体液压支柱。主要目的是为了保证工作人员的安全,所谓大倾角煤层就是指煤层倾角大于25°的煤层。其主要的改进部位是顶盖,由原来的通用式改为现在的防倒式。通过楔卡的安装与改进,使井下开采工作更为安全。其次,本次设计除了采用传统的绘图工具CAD画图外,还利用Pro/E进行三维实体造型,充分发挥出了Pro/E的优点,使商家与使用者对该产品在感观上有更进一步认识和了解。
关键词:大倾角顶盖防倒式楔卡三维实体造型
Abstract
Ascend and descend the horizontal move type stereoscopic stop the garage to is local in recent years of newly arisen property, the solution is big, inside city car parking the difficult exit consist in constructing mechanization stereoscopic stop the garage. The main purpose of designing aim as the current parking lot the problem that exits, and design a stereoscopic garage for with less place stopping putting more cars. The method depend on electrical engineering, trolley...etc. the ambulation the car regarding flat surface parking lot as the cores, and make use of the PLC to control the system to control the car the position to change into the. Consequently designed 125 hardware electric circuit for ascend and descending the stereoscopic garage of horizontal move types. Combine to proceeds to this the plait, and improved the speed. That method has the widespread meaning.
Want to realize this purpose, and must choose fit of contact, pass the the point to attain to make the electrical engineering the positive and negative function that turn. The heat of fit choice avoid because of the electric current after the electric appliances over big but result in of need not want to lose, and proceeds to carry the aegis. Route of travel of fit choice switch,then attain to position the function. Introduced the every variety stereoscopic stop the garage's construction, control the system and its characteristics, and give out stereoscopic stop that the garage's main function index sign, combined to stand opposite the design important point to stop the garage to proceeds the analysised with study.
Key words: Stereoscopic garage contact the electric appliances route of travel switch
