摘要煤仓作为煤炭生产运输中必须的中间存储装置，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，原煤会在高压下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。75592

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，出现过很多工人死亡的真实案例。而且随着我国科技的发展进步，机械生产越来越趋于流水线，越来越趋于自动化，传统的清理方法显然不符合大型煤矿的生产需求。煤矿清仓机器人的诞生正是迎合了高工作效率、高安全性这种趋势，不仅提高了煤矿生产率，而且解放了高强度的人力劳动。

中心回转式全液压清仓机设计研究打破了传统的人工清仓限制，使煤矿工人不再受繁重的体力劳动和恶劣的工作环境所困扰。清仓机器人也大大提高了工作效率

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、回转机构回路和提升机构回路。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。

The design of hydraulic system of rotary cleaning machine center

Abstract Bunker as coal production and transportation to the intermediate storage device, coal constant input and output of coal bunker。 Due to moisture and other impurities in raw contain, with the passage of time, coal will be under high pressure on the wall of the chamber to form a layer of bonding material。 The bond from the bunker wall surface is uneven, which not only hinders the flow of coal in the bunker, but also reduce the coal bunker of the effective space, reduces the efficiency of production, so the coal bunker to regular cleaning。

The traditional coal cleaning is by manual cleaning, the cleaning way not only the efficiency is low, but also has certain risk, there have been many workers died in the real case。 And with the development and progress of science and technology of the people's Republic of China, the Machinery production more and more tend to be more and more automated。, the traditional cleaning method obviously does not meet the production needs of large coal mine。 The birth of mine clearance robot is to cater to the high work efficiency, high safety of the trend, not only improve the productivity of coal mine, and the liberation of the high intensity of human labor。

Design and research of the center of the rotary hydraulic clearance machine broke the traditional manual clearance limit, make mine workers are no longer subject to heavy manual labor and harsh working environment plagued。 Clearing robot also greatly improve the work efficiency

Center rotary clearing machine hydraulic system is designed in this paper。 The hydraulic system altogether can be pided into four loop, loop of working mechanism, support mechanism circuit, concretion mechanism and slewing mechanism circuits。 In this paper, the use of conventional calculation method of the hydraulic system key components and auxiliary components were design, selection and calculation, and checking of key components。

There are 17 figures, 5 tables and 49 references in this paper。

Key words: rotary center  clearing machine  hydraulic system
