毕业论文摘要煤仓作为煤炭生产运输中重要的存储装置，原煤不断地输入和输出煤仓。由于原煤中含有水分和其他杂质，随着时间的推移，原煤会在仓壁上形成一层粘结物。这层粘结物使煤仓壁表面凹凸不平，不仅阻碍了原煤在煤仓中的流动，而且还减少了煤仓的有效空间，降低了生产效率，所以煤仓要经常性地进行清理。传统的煤仓清理方式是靠人工清理的，这种清理方式不仅工作效率低下，而且还具有一定的危险性，在煤矿生产自动化程度越来越高的今天，这显然不符合大型煤矿的生产需求。因此，该文设计并研究了一种中心回转式全液压清仓机，旨在实现矿用清仓设备的智能化和自动化，促进了安全本质化矿井建设进程的进一步开展。41057

首先，该文根据工况要求，肯定了全液压清仓机的动力源使用的是液压驱动，同时它的清煤方式使用的是中心回转的方式，而且也整体把握了整机的结构设计。这篇文章主要针对清仓机的支撑机构、回转机构和和工作机构等核心的零件进行设计和计算，三文模型的建模则采用的是依据的是UG软件来进行绘制的，同时根据ANSYS软件对静力学进行了液压清仓机的模型分析。
该文设计了中心回转式清仓机液压系统。该液压系统一共可以分为四个回路,分别是工作机构回路、支撑机构回路、回转机构回路和走形机构回路。本文使用常规计算方法对液压系统的关键元件和辅助元件进行选型和设计计算,并对关键元件进行校核。

Design and Simulation of structure of rotary hydraulic machine clearance center
Abstract
Coal bunker as an important storage device of coal production and transport,raw coal constantly input and output of bunker.Because coal contains moisture and other impurities, as time goes on, coal bin wall will form a layer of the adhesive.This layer of the adhesive will make the surface of coal silo wall uneven, not only impede the flow of coal in the bunker, but also reduces the available space of bunker,reducing the production efficiency,so bunker should be cleaned regularly.The traditional way to clean up coal bunker is rely on manual cleaning,this approach not only work inefficient,but also has a certain degree of risk,in the increasing high degree of automation of coal production today, which obviously does not meet the production needs of large coal mines.This paper designed and studied a central rotary hydraulic clearing machine,Therefore, this article designed and studied a central rotary hydraulic clearing machine, Aims to achieve intelligent and automated of mine clearance equipment, and promote the further development of the nature of the mine safety building process.
First, the paper according to the requirements of working conditions, affirmed the full hydraulic clearing machine power source using a hydraulic drive, at the same time, the use of the clean coal is in such a manner that the center of rotation, but also grasp the whole structure design. And core of this article mainly for clearing machine supporting mechanism, slewing mechanism and working mechanism and parts of the design and calculation, modeling of 3D model is used is based on is UG software to draw, at the same time, according to ANSYS software of static hydraulic cleaning the cabin model analysis.
This paper designs a central rotary cleaning machine hydraulic system. The hydraulic system can be pided into four loops, namely the work loop mechanism, a supporting mechanism circuit, rotating mechanism loop and contorts institutions loop. In this paper, the key components and auxiliary components of the hydraulic system are selected and calculated by the conventional calculation method, and the key components are checked.
