【摘要】 通过对气力输送技术和土的破坏理论的研究,借鉴目前国内外先进的钻尖结构,设计了一种适用于市政道路非开挖干法输送泥屑的非对称断屑槽变螺距螺旋面的新型钻头。通过对该钻头工作时的受力分析,建立了钻头的力学模型,为钻头参数的进一步优化及干法气力输送非开挖钻孔机器人的结构设计与计算奠定了理论基础。更多还原

【Abstract】 Through study of pneumatic conveying and soil damage theory and experiencing advanced drill structure of our country and abroad,a new asymmetrical clay chip drill is designed which has break chip groove and variable-pitch and is used dry clay chip pneumatic conveying in the process of trenchless drilling of urban road. The mechanical models are established after the mechanical analysis when the drill working. It is the basis of optimization of the drill parameters and structure design and calculation of trenchless drilling robots with dry clay chip pneumatic conveying systems.更多还原
