摘要 锚杆钻机是锚杆支护的关键设备，它影响着锚杆支护的质量——锚杆孔的方位、深度、孔径的准确性以及锚杆安装质量，又涉及操作者的人身安全、劳动强度与作业条件等。采用旋转切削方式破岩的单体锚杆钻机是目前钻孔机具的主导产品，但机体笨重、可靠性低，这些制约着它们进一步推广使用，迫切需要研制高性能的锚杆钻机机具。针对这一状况，本次设计主要针对全液压旋转推进型锚杆钻机进行设计。 全液压旋转推进型锚杆钻机是一部具有很大应用价值的工程机械，施工对象主要是硬度较大的岩石。全液压旋转推进型锚杆钻机因其工作压力高、扭矩大、动力系统不受外界影响，在一些场合下是合理的机型。它的出产必将推动我国的社会主义建设事业的全面发展。 本次设计主要涉及到以下几个部分： 1.采用履带式液压挖掘机液压系统的设计思想，对全液压旋转推进型锚杆钻机的液压系统进行重新设计，以满足各种工况的要求； 2.对整机的制造、使用、验收等技术制定了相关的技术指标。 关键词：全液压旋转推进型锚杆钻机，单斗液压挖掘机 Abstract Bolt rig is the key equipment, which affects the quality of bolt hole location, depth, accuracy and the bolt installation hole quality, it also involves the safety of the operator, labor strength and operating conditions. The monomer roofbolter by rotary cutting breaking rock has become the main trend of the production and development of drilling machines for bolt support. Heavy machine body and low reliability is one of the main common factors restricting them further sprdeading use. It is urgently necessary to develop a kind of roofbolter with high performance. According to the existing problem, the main aim of the design for the non-valve-hydraulic bolt rig design is as follows. Full hydraulic rotary propulsion type Roofbolter, is a great value of construction machinery, mainly for the large hardness of the rock. Full hydraulic rotary propulsion type Roofbolter, has its high working pressure, torque, power systems are not subject to outside influence, in some situations it is a reasonable to mode. It’s produced in China will promote the comprehensive development of socialist construction. This design mainly involves the following parts: 1. I used crawler excavator boom design, the impact of non-valve-type hydraulic bolter’s boom re-designed to meet the requirements of various working conditions. 2. On the machine’s manufacture, use, inspection and other technical develop the relevant technical indicators. Key words: Full hydraulic rotary propulsion type Roofbolter, Single bucket hydraulic excavators
