The invention discloses a construction method and device of a medium-length hole drilling machine in a raise, and belongs to the technical field of mining engineering. The problem that medium-length holes are difficult and inconvenient to drill in narrow courtyards is mainly solved. The device comprises a platform supporting structure and a moving structure. The supporting structure comprises a base, a telescopic lead screw, a main frame body, a safety fence and a safety cover plate. The moving structure comprises a lower disc pulley, a front-back moving guide rail and a fixing frame. The footwall pulley is close to the footwall of the ore body, so that the platform integrally moves up and down in the courtyard; the drilling machine is installed on the fixing frame and can move front and back along with the front-back moving guide rail, and the angle of the drilling machine can be freely adjusted. The method has the advantages of being flexible and convenient to operate, high in construction safety and the like, and the efficiency and safety of stope blast hole construction are remarkably improved.
