Abstract
The invention relates to a coal mine underground drill rig, in particular to an underground drill rig with complete functions which is separated into a front part and a back part capable of walking separately and is connected and combined after arriving at a drilling field. The drill rig is separated into a front part and a back part, so that the size is reduced effectively, a sub-walking function is provided, convenience is brought for drilling in the drilling field, and the gallery suitability of the drill rig is greatly enhanced. By adopting the drill rig, the problem of difficulty in controlling coal mine gas since the conventional overlarge drill rig cannot enter a coal mine with a small production scale is solved. In the drill rig, a hydraulic station of the entire drill rig is separated from the entire drill rig to form an independent walking module; a small-sized walking hydraulic station is arranged in the rest of the entire drill rig, so that the size of the entire drill rig is effectively reduced; and the two parts are connected through an oil pipe after arriving the drilling field to form an entire coal mine underground drill rig. The drill rig is convenient to transport, has a small size, is flexible for arranging in the drilling field, and has high suitability for small drilling fields.
