Rock drilling machine drilling direction measuring device and method

The invention provides a rock drilling machine drilling direction measuring device and method, and relates to the field of handheld geological drilling machines. A first steel bar, a second steel barof an orientation rod and a third steel bar of the orientation rod are arranged in a rectangular opening mode, an iron clamp is fixedly welded to one side of the third steel bar, a single-section universal joint is arranged at the bottom end of the first steel bar, and the first steel bar is hinged with the steel plate through the single-section universal joint. According to the rock drilling machine drilling direction measuring device and method, during drilling, the drill rod and the orientation rod are firmly connected through the iron clamp and can be fixed in time after the angle is determined, the space direction of a hole is directly determined through a protractor, the drilling is stable and accurate, and the angle precision during drilling is greatly optimized.
