摘要
 随着现代化建设脚步的加快，矿山机械也在不断的发展，但由于能源和建设等施工要求的增大，掘进机的性能还不能够完全适应，所以迫切要求设计出新型掘进机以适应工况要求。
 横轴式掘进机的总体方案设计对于整机的性能起着决定性的作用。因此,根据掘进机的用途、作业情况及制造条件,合理选择机型,并正确确定各部结构型式,对于实现整机的各项技术指标、保证机器的工作性能具有重要意义。
 本设计是对横轴式掘进机总体方案设计与行走系统设计。通过应用掘进机设计的一系列知识，对掘进机的悬臂支撑机构；装运机构；行走机构；转载机；冷却喷雾系统；液压系统；电气系统加以分析，并且进一步对行走系统做了优化设计。最后使设计的系统达到本设计的目的，使该掘进机在满足原有要求的情况下实现体积小、成本低、效率高、结构简单、使用维护方便的要求。

ABSTRACT
 With the accelerated pace of modernization construction, mining machinery are also constantly development, but due to energy and building construction requirements of the increase, boring machine is not able to completely meet the performance, there is an urgent request to design a new boring machine to adapt to conditions Requirements.
 The boring machine design of the overall plan for the performance of the play a decisive role. Therefore, in accordance with the purposes boring machine, operating and manufacturing conditions, a reasonable choice of models and determine the right structure of ministries, for the achievement of the various technical indicators to ensure that the machines work performance is of great significance.
 The design is so boring machine to design specific analysis, and for some boring machine running the design calculations. Through the application of a series of boring machine design knowledge, the boring machine cantilever support institutions; shipment; walk; reproduced; cooling spray system; hydraulic system; electrical system analysis, the operating system and further optimize the design done . So that the final design of the system designed to achieve this purpose, so that the boring machine to meet the requirements of the original under small size, low cost, high efficiency, simple structure and facilitate the use of safeguard requirements.
Key words: Axial-boring machine；Overall Design；Operating system design.
