摘要
 
 掘進機是煤炭生產和建設的基礎工程，在煤炭工業中具有基礎性的關鍵地位。本設計力圖結合行業標準和設計規范，根據工作要求和設計目的進行掘進機總體方案設計與液壓系統設計，確定符合要求的掘進機的總體參數。
 在液壓系統設計部分，基本上確定各零部件的液壓使用原理及參數計算。這里分析計算了截割部、行走機構、裝運機構、中間運輸機等載荷分析。馬達部分的確定：裝載部的星輪機構馬達、行走機構的驅動馬達、中間運輸機的驅動馬達等。油缸部分的確定：升降油缸、回轉油缸、伸縮油缸、履帶行走機構的張緊油缸、鏟板部的升舉油缸的計算設計。
 液壓缸的結構設計部分，進行了伸縮油缸的機構設計計算，并繪制零件圖。也進行了泵站的參數計算確定和液壓系統的計算，評估液壓系統性能。
 最后進行掘進機的通過性分析與穩定性分析。
關鍵詞：掘進機；總體方案設計；液壓系統
 
 
Abstract
 
 Roadheader is the foundation of the Coal Industry. In the coal industry, Roadheader is in the key foundation status. This paper attempts to combine industry standards and design specifications, in accordance with the requirements and design of general purpose, make general design of longitudinal roadheader and design of hydraulic system, determined to meet the requirements of the overall tunneling machine parameters.
 In the design of the hydraulic system, this paper basically establishes the principle of the use of hydraulic components and parameters. Here analysis of the cutting unit, operating agencies, shipping agencies, transport planes, and other intermediate load analysis. The set of Motor part include: the motor of star ferry carrying, the drive motor running, the middle of the drive motor and other transport planes. Part of the fuel tanks identified: the fuel tank movements, rotary fuel tank, the fuel tank of stretching, walking track the take-up fuel tanks, shovel board or give the Department of the calculation of the fuel tank design.    Cylinder part of the structural design, the paper discusses a telescopic design of the fuel tank of the bodies, parts and drawing plans. Also had a pumping station and determine the parameters of the hydraulic system, hydraulic system performance assessment.     Finally, roadheader through analysis and stability analysis is discussed.
Key words: roadheader; Overall concept design; hydraulic system
