Hydraulic driving two-stage feeding dovetail groove guiding asymmetrically-arranged anchor drilling machine

The invention belongs to the technical field of anchor drilling machines, in particular to a hydraulic driving two-stage feeding dovetail groove guiding asymmetrically-arranged anchor drilling machine, solving the problems existed in the conventional anchor drilling machine. A carriage assembly of the hydraulic driving two-stage feeding dovetail groove guiding asymmetrically-arranged anchor drilling machine comprises a carriage; the rear end of the carriage is of an outer dovetail shape; the rear end of the carriage and a front guiding pressure plate with an inner dovetail shape form a translational pair; a short feed oil cylinder and a long feed oil cylinder are respectively arranged outside the carriage assembly and symmetrically arranged at two sides; the back side of a frame assembly is connected to a rear guiding pressure plate; the rear guiding pressure plate is of the inner dovetail shape; the rear guiding pressure plate and an outer dovetail guide rail in the sleeve of a support column assembly form t
