The invention discloses a three-shaft remote-controlled drill pipe vehicle for a coal mine. The three-shaft remote-controlled drill pipe vehicle for the coal mine comprises a crawler base plate arranged at the bottom and used for supporting, an automatic drill pipe box fixed on the upper portion of the crawler base plate, a pump power system for providing power and a control module. The pump powersystem outputs high pressure oil to power the crawler base plate and the automatic drill pipe box. The automatic drill pipe box includes a mechanical arm with a manipulator, a drill pipe box used forplacing a drill pipe and with drive mechanisms transversely arranged on both sides and sliding mechanisms arranged on both sides of the drill pipe box and with vertical sliding rails. The control module realizes the signal control of the automatic drill pipe box, the crawler base plate and the pump power system. According to the three-shaft remote-controlled drill pipe vehicle for the coal mine,workers are free from poor construction sites or away from first construction sites, direct injury to the workers in emergency situations is avoided, at the same time, the labor intensity is reduced,the work performance is stable, the operation is simple, and the three-shaft remote-controlled drill pipe vehicle for the coal mine is suitable for promotion in the industry.
