摘 要
掘进机在当今的社会生产中,无论是在矿物开采,还是在巷道的开掘都是有着重要的地位。
EBZ-160型悬臂式掘进机,它是一种能够实现连续切割,装载,运输的掘进设备。其特点是截割头可以伸缩达到 500 mm ;有提高机器稳定性的后支撑装置;刮板运输机和铲板部均采用低速大扭矩液压马达直接驱动,减少故障环节;行走部采用液压马达驱动;履带采用油缸张紧装置;刮板链的涨紧均采用弹簧与油缸组合的涨紧装置;截割电机为水冷电机,有热敏保护;在液压系统为液压锚杆钻机留有液压接口。该机截割效率高,机器稳定性好,操作与维护方便,运行安全可靠。
本论文主要对掘进机的整机部件,总体结构,液压系统,进行了具体的说明、分析、计算、设计和校核;其中对液压系统进行了详细的设计。

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.
