【摘要】 液压锚杆钻机是岩土锚固工程的关键设备,对锚固施工质量有重要影响。本文在分析液压锚杆钻机旋转机构工作原理的基础上,提出了前腔常压式冲击旋转型液压锚杆钻机动力头。据此进行动力头结构设计,并运用Pro/ENGINEER建立旋转机构和前腔常压式液压冲击机构的三维数字化模型并进行虚拟装配和优化;然后将其导入到动力学仿真分析软件ADAMS中,对动力头进行机液耦合动力学仿真。结果表明经过优化的旋转冲击型动力头在符合土锚钻机的工况要求,体积小,冲击力稳定,运行平稳。本文综合运用现代设计方法、三维CAD软件、仿真分析软件,对前腔常压式冲击旋转型液压锚杆钻机动力头进行设计,为液压冲击动力头机构的设计提供了重要参考依据,所采用的思想和方法对开发类似产品具有一定的指导意义和参考价值。更多还原

【Abstract】 Hydraulic roofbolter is the key equipment for Ground Anchorage, and have an important impact on project quality, for ground anchorage engineering.Base on analysizing of revolving apparatus hydraulic roofbolter, that the impact of drilling speed, then a design method has been carry out, that it adopted the driving head of cavity-front constant-pressure impact-rotary hydraulic roofbolter. Accordingly, designed the structural of the driving head and revolving apparatus; Established the 3D digital model of revolving apparatus and impact institutions, and carry on virtual assemble by Pro / ENGINEER software,. Then the model is imported into ADAMS (Automatic Dynamic Analysis of Mechanical System)software and the machine-hydraulic coupling simulation of hydraulic control system was done. The results showed that optimized the driving head of impact-rotary with small size, impact of the stability and operation stability.The paper, optimizing the use of modern design, 3D CAD software, simulation software, optimized design for the driving head of cavity-front constant-pressure impact-rotary hydraulic roofbolter. and provided an important reference. The ideas and methods of this paper have a certain significance and value for the development of similar products.更多还原
