 摘要

 矿山企业的井下水仓是同一开采作业水平各处水的流经通道，并承担着沉淀水中的煤粉及杂质作用。水仓的线性长度一般为300～1000米，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，水仓被淤满后必须及时清理，否则会影响矿井的正常排水，导致淹井等重大事故。国内目前所采取的主要清仓方式多为人工清理。由于作业空间狭窄，工作环境恶劣，工人劳动强度大，作业效率低，鉴此，需要开发一种矿山水仓清理设备，实现矿山辅助生产的机械化。
 矿山水仓清理机械化是矿山企业一直未能很好解决的难题。目前，从事矿山机械化的技术人员虽然研发了一些不同形式的清仓设备，但这些设备存在着效率低，或费用高、或维护困难等不同缺点。所以开发一种高效可靠，符合井下工作要求的水仓清理机械具有非常重要实际工程意义。该课题源于企业实际，研究目标是提高清理水仓效率、降低工人劳动强度。
 作者所设计的履带式清仓机主要有行走装置、工作装置、传动系统、操纵系统等组成。本文介绍了履带式清仓机工作装置的设计思路与过程。工作装置是体现履带式清仓机作业效率关键部件。文中在国内外现状分析、方案设计的基础上对工作装置的总体设计、铲斗运料过程的变轨结构设计、传动零部件设计及计算、物料铲装仿真进行了较详细的阐述。

Abstract

 The underground mine water warehouse is the same level of mining operations throughout the water flowing through the channel, and assume the precipitation of pulverized coal and water impurities role. Water stores linear length generally 300 to 1,000 meters, the exit of the row to pump water from the ground. As the deposition of pulverized coal and impurities, water warehouses were full after the deposition must be cleared in time, otherwise it will affect the normal mine drainage, leading to submerged wells, and other major incidents. China currently taken by the major clearing the way for many of liquidation.As operating room narrow, poor working environment, workers in labour-intensive, low operating efficiency, the view of this, the need to develop a mine clearance equipment store water, and mine-assisted  production mechanization.
 Mine water clean-up mechanized warehouse is a good mine has been unable to resolve the problem. At present, the mechanization in mining technology research and development staff Although a number of different forms of clearing equipment, but the equipment there is a low efficiency, or the high cost, difficulties in maintaining or different shortcomings. Therefore, the development of a highly efficient and reliable, consistent with the requirements of the underground water clean-up machinery warehouse is very important practical significance. The issue stems from the actual business, research goal is to improve the water clean-up warehouse efficiency and reduce labor intensity of workers.     Designed by the author tracked the clearing of a major operating unit, installation work, drive system, control system and other components. This article tracked the clearing work for the design and installation process. Installation of the work is tracked clearing machine operating efficiency of key components. At home and abroad in the text of the status quo analysis, design work on the basis of the device design, process the material transported bucket swing structural design, design and transmission parts, materials simulation with a spade a more detailed exposition. Key words: mud cleaning machine, working equipment,continuous loading
