    摘要:

    冲击回转挤密法钻进是一种先进的土层锚杆成孔工艺方法\[1\]。双向气动冲击机构是其成孔设备双向气动潜孔锤的核心机构,配气行程长度的设计是否合理关系到潜孔锤正向冲击时的工作性能及能否实现有效的反向冲击。在分析配气原理的基础上,采用分段计算法,结合有限差分原理对双向气动冲击机构的配气行程长度设计进行了研究,并提出了双向气动冲击机构配气行程长度比的设计参考值。

    Abstract:

    Impact rotary compacting drilling is a kind of advanced soil anchor hole forming method, two-way pneumatic DTH hammer is the main equipment used for it. Its critical device is two-way pneumatic impact mechanism; the gas distribution stroke design is related to the DTH hammer conventional working performance and realization of effective reverse impact. Based on the analysis on DTH hammer gas distribution theory, using section calculation method and finite difference principle, the study was made on the design of gas distribution stroke length of two-way pneumatic impact mechanism and put forward the design reference value of gas distribution stroke length ratio.
