摘 要
随着高、重、大建筑的增多,锚杆支护技术应用越来越广泛,随之钻凿锚孔的锚杆钻机也得到了快速发展。
本文针对现有锚杆钻机存在的坚硬夹层及坚硬围岩等的不适应问题,在收集、查阅大量资料的基础上,提出了冲击旋转式液压锚杆钻机方案,并对其进行设计研究,因锚杆钻机的机构比较复杂,所以重点放在锚杆钻机的液压系统设计。首先,在对冲击旋转钻孔破岩机理进行分析的基础上,结合冲击旋转式液压锚杆钻机的总体方案设计,制定出冲击旋转式液压锚杆钻机的液压工作原理方案,并对组成液压系统的各个子系统的原理和特点作了详细的分析。在此基础上,对锚杆钻机的液压动力装置和系统原理进行了具体设计,通过计算选取了各主要元件,利用三维设计软件进行管路连接和系统布置。

Abstract
Suspension roof support technical application increasingly abroad in company with high, weightiness, large structural manifold, came along of the jumbolter with anchor eye too get know clearly instant development.
This text aim at existence jumbolter available stiffness interlining or stiffness wall rock uniform maladjustment problem,set know clearly impact rotary system hydr- aulic pressure jumbolter proposal combine versus his proceed design studies,on the foundation of collection, consult a great amount of information. because of the jumbolter's institution compare intricacy,so emphases lay in jumbolter 'hydraulic system design. First of all,above versus impact rotary boring broken rock mechanism proceed analytic foundation,incorporation of the impact rotary system hydraulic pressure jumbolter 'general planning design,map out impact rotary system hydraulic pressure jumbolter 'hydraulic pressure principle of operation scheme,and combine versus compose hydraulics severalty subsystem theory and point did know clearly detailed analyses. Both that of hereon foundation upper,versus jumbolter hydraulic power unit and system theory proceed know clearly detailed design,through the medium of figure choose know clearly each major component,turn three-dimensional design software proceed ducting connection and system layout to advantage up.
