rock drill

To address long-standing challenges in tunnel construction，such as difficulties in controlling over-excavation and under-excavation，high consumption of jumbo materials，and excessive energy consumption，this article provides a high-performance rock drill with a small edge-to-center distance ( model:

The numerical control processing technology is used to process the drilling tool, and the high-precision numerical control processing center is adopted, by matching the special wear-resistant coating cutter, the precision error of each process can be reduced by precise measurement, the production

The three-arm hydraulic rock drilling jumbo is equipped with a high-performance imported rock drill. If the rock drill breaks down frequently during tunnel excavation, it will seriously affect the construction progress and increase the construction cost. This paper analyzes the working principle

In this paper, through the description of the oil emulsification failure analysis and treatment results of the hydraulic system of the Atlas COP1838HD+ rock drill equipped with TBM, the arrangement and working conditions of this type of rock drill on the TBM equipment are different from those of

Through the analysis of the mechanism of small excavator and rock drill, the advantages and disadvantages of the two and their correlation degree are found.Adding various auxiliary tools on the excavator can not only expand the application scope of the excavator, but also adapt to
