The utility model discloses intelligent drilling detection equipment based on a dobby drill platform and a detection method thereof. The device comprises a multi-arm trolley, a drill rod, a detectiondrill, a geophysical prospecting detector and vehicle-mounted test equipment, a geophysical prospecting detector is arranged on the basis of one drill rod of an original multi-arm trolley to form a detection drill, the detection drill is connected with a vehicle-mounted test device through the geophysical prospecting detector, the detection drill is used for detection after the drill rods drill holes, and correction and adjustment of the drill holes are carried out according to detection data when the rest drill rods drill holes. The tunnel drilling device solves the problems that in the original tunnel drilling process, earlier-stage sampling is needed, and the drilling efficiency is low, and has the advantages of being simple in structure, integrating intelligent and automatic drilling detection, and being high in accuracy, simple and applicable in method and high in drilling efficiency.
