Inheriting the tradition, combined with the actual situation, on the basis of enriching and improving the "valveless" pneumatic rock drill mechanical simulation concept, the "three control" design concept is supplemented; In terms of structure, the implementation of one modification, three

With the continuous improvement of the design and manufacturing technology of large-scale tunnel machinery and its intelligence, the large-scale mechanized construction technology of drill-and-blast tunnels is becoming more and more mature. In this paper, the fully computerized 3-arm rock drilling

The article compiles diameter data of 11 dual-control rock drills and 4 rear-control rock drills from Epiroc. The ratio range of stressed areas of the piston in return and power strokes is determined. Based on the analysis of ratio data, the article points out using the design variables based on 3-

In order to improve the quality of tunnel construction, especially the weak surrounding rock tunnel, and ensure its construction safety, the traditional excavation method is replaced by a fully computerized three-arm rock drilling rig, so as to speed up the tunnel construction progress and enhance
