摘 要
隨著高、重、大建筑的增多，錨桿支護技術應用越來越廣泛，隨之鉆鑿錨孔的錨桿鉆機也得到了快速發(fā)展。
本文針對現(xiàn)有錨桿鉆機存在的堅硬夾層及堅硬圍巖等的不適應問題，在收集、查閱大量資料的基礎上，提出了沖擊旋轉式液壓錨桿鉆機方案,并對其進行設計研究，因錨桿鉆機的機構比較復雜，所以重點放在錨桿鉆機的液壓系統(tǒng)設計。首先，在對沖擊旋轉鉆孔破巖機理進行分析的基礎上,結合沖擊旋轉式液壓錨桿鉆機的總體方案設計，制定出沖擊旋轉式液壓錨桿鉆機的液壓工作原理方案，并對組成液壓系統(tǒng)的各個子系統(tǒng)的原理和特點作了詳細的分析。在此基礎上，對錨桿鉆機的液壓動力裝置和系統(tǒng)原理進行了具體設計，通過計算選取了各主要元件，利用三維設計軟件進行管路連接和系統(tǒng)布置。
關鍵詞：錨桿鉆機；液壓系統(tǒng)；回轉沖擊器
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.
