Steel wire rope guiding device of vertical shaft type drilling machine

The invention provides a steel wire rope guiding device of a vertical shaft type drilling machine. The steel wire rope guiding device comprises a winch, a cylindrical cam assembly, a shifting fork assembly and a fixed pulley assembly. Based on the cylindrical cam structure, the steel wire rope guiding device is arranged on the rack of the winch, effective guiding of the vertical shaft type drilling machine steel wire rope is achieved, the phenomena of steel wire rope abrasion and winding drum side wall damage caused by tight contact of the steel wire rope and the winding drum side wall under the action of lateral component force are avoided, and the service life of the steel wire rope is greatly prolonged. Meanwhile, by adjusting the transmission ratio between the friction driving wheel and the friction driven wheel, the steel wire rope can be evenly wound on the winding drum, the rope pressing and rope stacking phenomena are avoided, a drilling tool in a hole is made to ascend and descend stably, and drillin
