矿山水仓清淤机工作装置的设计 摘要：水仓是井下同一水平处水的流经通道，同时还肩负着沉淀水中的煤粉及杂质的作用，其出口处的清水由水泵排至地面。由于煤粉及杂质不断沉积，水仓被淤泥装满后必须及时的清理，否则会影响矿井的正常排水，甚至导致淹井等重大事故。这也是本课题中所要研究开发的清淤机的功用所在。 矿山水仓清理的机械化是众多矿山企业多年来一直未能很好解决的难题。随着煤炭工业的机械化、自动化水平的不断提高，实现矿山水仓清淤的机械化已经是摆在矿山企业面前急需解决的问题。以前的各种清仓方式和设备存在着工期长、效率低，或是费用高、维护困难等不同缺点。所以研制一种全新的、高效可靠的、符合井下工作要求的水仓清理工作装置具有非常重要和长远的意义。该课题源于目前企业的实际情况提出，且需求量大。全国有近万家矿山开采企业，该课题的研究对提高清理水仓效率、降低工人劳动强度意义重大，也拥有广阔的市场和应用前景。 本论文介绍了该新型矿山清淤机的工作装置的设计思路与过程。在该课题中所研制的矿山清淤机应当具有以下主要特点：（1）体积小，结构紧凑，机动灵活可实现原地转向，特别适用井下狭小空间里作业；（2）工作装置可以相对车身进行旋转，本身不动的情况下也同样可以铲泥工作；（3）该工作装置应该具有通用性，改型容易；（4）该工作装置应该实现连续式的装载要求，切实提高井下的工作效率和安全可靠性。根据上述的功能要求，本文作者在查阅了许多相关文献资料并分析比较了国内外现有对水仓清理技术的研究的优缺点基础上，确定了该工作装置的设计方案并进行了相应的结构设计。 本论文通过对国内外现状的分析、方案设计、工作装置的结构设计以及零部件的设计与计算等多方面阐述了该新型工作装置的创新。 关键词：清淤机；工作装置；圆环链；连续装载 Abstract：Underground sump is the channel where the water flows through under the mine well. And it should precipitate the coal and impurities in water at the same time, and the clean water is drained off through the pumps. Because the continuous precipitation of the coal and impurities, the storage must be cleaned in time after being filled with the sludge, otherwise it may affect the normal mine drainage, and may even lead to the big incidents as drown the well. This is the issue in which the research of the clean mud machine’s functions lie. The mechanization of the clean machine used in the mine sumps is the problem which many mining enterprises have failed to properly resolve. With the level of mechanization and automation in mining industry improved, the sump’s cleaning is mechanized has been placed before the mining enterprises which need to solve. The previous clearing methods and equipment exists many different disadvantages, such as long period, inefficient, or the high cost and difficulty of maintenance. Therefore, it is very important and long-tem significant that to develop a new sump cleaning machine, which is highly efficient and reliable, and underground work in line with the requirements. This issue stems from th
