The invention belongs to the technical field of transmission of mine hoists, and particularly provides a standby power assembly based on a head sheave of a mine hoist, which mainly comprises a speed regulating device, a motor, a photoelectric encoder, a clutch, the head sheave and the like. The head sheave is made of high-strength, the steel wire rope liner is preferably made of a high-friction-coefficient material, and the friction coefficient can meet the requirements of the bearing load in the standby and emergency lifting process under the traction force generated under the action of the lifting steel wire rope and the strength of the head sheave; when needed, the clutch is closed, under the action of the speed regulating device, the alternating-current motor operates at the rotating speed corresponding to 0-fe (rated frequency), the direct-current motor operates at the rotating speed corresponding to 0-Ue (rated voltage), the head sheave is driven by the clutch to rotate, the head sheave drives a lifting steel wire rope to operate through a high-friction liner nested in the rope sheave, and the lifting steel wire rope is driven by the high-friction liner to rotate. And a standby or emergency lifting task is completed. Under the normal condition, the clutch is separated, and the standby power assembly is in a standby state.
