Targeted at the domestic market, YYG18U hydraulic rock drill has seen its main applications in hard rock drilling and construction such as tunnels and mines. Based on more than 2 years of using experience of YYG18U hydraulic rock drill from Epiroc, the paper covers the structure

In this paper, in the light of the principle of impact drilling work of hydraulic rock drill, the main factors of affecting the rock drill pore forming efficiency are analyzed. This provides the reference for hydraulic rock drill design and optimization of hydraulic rock drill performance parameters

With the rapid development of Chinas high-speed railway construction，the construction standards continue to increase． In order to ensure the rapid excavation of long and large tunnels，to ensure the safety of operators，to reduce the number of operators，and to reduce labor intensity，

The rotation chuck bushing is one of the important parts of the buffer mechanism in hydraulic rock drill ZYYG170A, and also one of the parts that is frequently damaged during operation. Whether in the buffering process or the resetting process,Tish arttcle chuck bushing is always clamped between the

With the rapid development of science and technology in China, great changes have taken place in the construction technology of tunnels. "Mechanization, informatization and intelligence" has become the inevitable trend of future development. Combined with the application of multi-arm rock

A single-arm rock drilling jumbo rig is used to drill holes in Ganyue Road, Chongqing, and then the rock stratum is split by hydraulic fracturing machine, and then removed by excavator. Large-diameter drilling increases the drilling tool loss of single-arm rock drilling jumbo.
