Abstract

The invention relates to a rock drilling pneumatic wrench which comprises a linear motor component, a drill rod component and a connecting component. The linear motor component serves as a driving source and is connected with the drill rod component through the connecting component to perform rock drilling operation. According to the rock drilling pneumatic wrench, a linear motor serves as a driving source, a drill rod is fixed by a drill rod guide seat, impact force is transferred by a screw nut and an elastic part, and the rock drilling pneumatic wrench has the advantages of low vibration and noise.

Description

technical field [0001] The invention relates to the field of rock drilling with jackhammers, in particular to a rock drilling gun. Background technique [0002] The so-called rock drilling is to drill blastholes in rocks (or ores). In mining engineering, eyeholes are often used to fill explosives for blasting. Sometimes large-diameter holes are formed by rock drilling, and they are directly used as wells without blasting. The holes are also used for geological exploration, material transportation, installation of bolts, pipelines, cables and other facilities, or as oil and gas wells in oil production projects. Therefore, rock drilling is also widely used in related rock crushing projects such as geology, petroleum, hydropower, transportation, etc. [0003] At present, most of the rock drilling is powered by a cylinder-type jackhammer. The jackhammer uses compressed air as power to push out and push back the chisel. When the chisel strokes, it impacts the rock and drills a ...
