摘　　要：在岩土工程穿凿作业中,气动冲击器被广泛应用于多种中、高硬的可钻性差的坚韧性岩石开凿。开凿过程中,要求气动冲击器具备良好的排岩效果、低的岩渣重复破碎率、高的钻头耐磨性和钻进效率。通过对HC80型气动冲击器的优化设计,利用最新凿岩理论进行设计计算,验证证实结构优化后具有理想能量传递效果,具有凿岩速度快、耗风量低的优点。气动冲击器采用先进的热处理工艺,保证稳定的使用性能、较高使用寿命。优化后前接头和与外缸采用多头螺纹连接结构设计,方便钻头拆卸和维修维护。In rock and soil engineering,pneumatic hole impinger is widely used in many kinds of hard and tough rock with poor drillability.In the process of drilling,it is required that the pneumatic hole impinger has good effect of discharging rock,low rate of repeated crushing of rock slag,high wear resistance of the bit and drilling efficiency.The design and calculation based on the latest drilling theory has the ideal energy transfer effect,fast drilling speed and low air consumption.It adopts advanced heat treatment technology to ensure stable performance and high service life.The front connector and the outer cylinder are connected with multiple screw threads,which is convenient for bit disassembly and maintenance.
