摘 要
掘進機在當今的社會生產中，無論是在礦物開采，還是在巷道的開掘都是有著重要的地位。
EBZ-160型懸臂式掘進機，它是一種能夠實現連續切割，裝載,運輸的掘進設備。其特點是截割頭可以伸縮達到 500 mm ；有提高機器穩定性的后支撐裝置；刮板運輸機和鏟板部均采用低速大扭矩液壓馬達直接驅動，減少故障環節；行走部采用液壓馬達驅動；履帶采用油缸張緊裝置；刮板鏈的漲緊均采用彈簧與油缸組合的漲緊裝置；截割電機為水冷電機，有熱敏保護；在液壓系統為液壓錨桿鉆機留有液壓接口。該機截割效率高，機器穩定性好，操作與維護方便，運行安全可靠。
本論文主要對掘進機的整機部件，總體結構，液壓系統，進行了具體的說明、分析、計算、設計和校核；其中對液壓系統進行了詳細的設計。
關鍵詞：掘進機；橫軸式；總體設計；液壓系統
Abstract
Boring machine in the contemporary social production, both in mineral exploration, exploitation or in the roadway are important position.
EBZ-160-cantilevered boring machine, it is to achieve a continuous cutting, loading, transport of tunneling equipment. Its characteristics are cutting head can be extendable to 500 mm; enhance the stability of the machine after the Support Unit; scraper and shovel board of the transport planes are used large low-speed torque direct drive hydraulic motors, reducing fault links run by the Department of Pressure motor-driven; tracked by the fuel tank of tensioning devices; scraper chain rose bear in spring and fuel tanks are used up tight combination of devices; cutting the electrical motors for water-cooled, thermal protection in the hydraulic system for hydraulic Roofbolter have a hydraulic interface. Cutting efficient aircraft, machinery good stability, operation and maintenance of convenient, safe and reliable operation.
The present paper mainly to mechanical boring machine's complete machine part, the gross structure, the hydraulic system, has carried on the concrete explanation, the analysis, the computation, the design and the examination; And has carried on the detailed design to the hydraulic system.
