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 continuous development and innovation of highway tunnel construction technology，manual drilling and blasting of tunnels is gradually being replaced by mechanized supporting construction. Summarizes the efficiency and benefit of the three-arm rock drilling rig in the mechanized constructio

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.
