Description
Technical field
The present invention relates to drilling rig technique field more particularly to a kind of borer frame angle regulation positioning devices.
Background technique
Coal mine gas content is higher, in order to ensure safety, needs to bore drawing-off gas hole in underground coal mine, thus handle watt
This is emitted.There are many coal mine down-hole drilling machine class at present, have manually, automanual, however manual, automanual coal mine
Drilling machine needs multiple people's cooperatings, and underground coal mine spatial complex, and punching angular range is wide, and manual adjustment punches angle
Heavy workload, perforating efficiency are low.In order to adapt to the punching of underground coal mine multi-angle, now with a kind of automatic drilling rig of crawler type,
