摘要中国是一个煤炭生产大国,煤矿井下煤仓是井下煤炭运输的咽喉部位,传统的清仓方式为人工清仓,其劳动强度大,且仓内有有毒气体和仓壁塌方等一直是一个难解决的问题,清仓机器人的出现无疑可以实现了机械化清仓,提高清仓安全性。70351

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摇臂式全液压清仓机，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。

首先，根据工作条件的要求，确定了全液压间隙电机的功率源，使用液压传动清煤。分析和确定机床主要技术参数，在此基础上，对关键部件的支承机构和摇杆机构和工作机构进行了设计计算，设计了液压系统的摇杆机构。采用常规的计算方法，对液压系统的关键部件和辅助部件进行了选型和设计计算。

Abstract

China is a big country of coal production and coal mine coal bunker is the throat in the underground coal transportation, the traditional way of clearing for artificial clearance, the labor intensity is large and warehouse have toxic gases and the silo wall collapse has been a problem difficult to solve, clearing robot can undoubtedly be mechanized clearing is implemented to improve the security of the clearance.

As an important coal storage device of coal production and transportation of coal to the input and output of coal. As the raw coal contains water and other impurities, with the passage of time, the coal will form a layer of bonding material on the wall. Make this layer of bonding material 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, reduce the production efficiency, so should regularly clean coal bunker. The traditional coal cleaning is by manual cleaning, the cleaning way not only the efficiency is low, but also has certain risk, in the coal mine production automation degree is more and more high today. This is clearly not in line with large-scale coal production needs. Therefore, the design and study the a rocker type full hydraulic clearing machine, designed to achieve the intelligence and automation of mine clearance equipment, to promote the further development of intrinsically safe mine construction process.

First, according to the requirements of working conditions, the power source of the whole hydraulic gap motor is determined. The main technical parameters of the machine tool are analyzed and determined. Based on this, the supporting mechanism and the rocker mechanism and the working mechanism of the key parts are designed and calculated, and the rocker mechanism of the hydraulic system is designed. The selection and design calculation of the key components and auxiliary components of the hydraulic system are carried out by the conventional calculation method.
