YDT35型电动凿岩机1985年研制成功,经一年多的生产性试验,于1986年11月通过部级鉴定并投产,是具有国内先进水平的新型电动凿岩机。该机可在硬岩中钻凿炮孔,可不停机退钎,还可利用空打处理卡钎事故。是我国短浅坑道掘进中,钻凿炮孔用电动凿岩机较理想的换代产品。现仅就该机补气机构的补气与补气压力作一粗浅的探讨。 YDT35型电动凿岩机采用偏心块式两个自由度的冲击机构,这种机构结构简单、可
YDT35 electric rock drill was successfully developed in 1985, after more than a year of productive test, passed the ministerial appraisal and put into production in November 1986, it is a new type of electric rock drill with advanced domestic level. The machine can drill holes in the hard rock drilling, without stopping the brazing, but also the use of air handling card brazing accident. It is an ideal replacement product of electric rock drill for drilling chisel hole in China’s shallow shallow trench tunneling. Now only on the mechanism of qi and qi gas pressure make a superficial discussion. YDT35 electric rock drill eccentric two-degree-of-freedom impact mechanism, this mechanism is simple, can
