The invention discloses a shaft derrick head sheave, which comprises a lifting mechanism, a head sheave body, an oil storage part arranged on the head sheave body, a power part arranged on the head sheave body, an extrusion part arranged in the oil storage part, a spraying part arranged between the oil storage part and the head sheave body, and a pressurizing mechanism, comprising an inertia part arranged on the head sheave body and a piston part arranged in the inertia part. According to the shaft derrick head sheave, when the head sheave body finishes winding and unwinding of a steel wire rope, due to inertia, the counterweight handle continues to rotate by a certain distance, so that the piston block is driven to move along the annular frame, reciprocating motion of the piston block pressurizes the interior of the extrusion part, maintenance oil in the oil storage tank is sprayed to the surface of the steel wire rope through the atomization spray head, automatic spraying is achieved, and labor force is not
