The invention discloses an elevator traction sheave with an emergency protection function and a protection method thereof, and relates to the technical field of traction sheaves, the elevator traction sheave comprises a sheave body, mounting frames and an intelligent monitoring module, wheel shafts are arranged on the surfaces, close to each other, of the mounting frames in a penetrating mode, the outer surfaces of the wheel shafts are sleeved with the sheave body, and rope grooves are formed in the outer walls of the wheel bodies; and an intelligent monitoring module is mounted at the top of the mounting frame and comprises a wear detection unit, an operation state detection unit and an offset detection unit. The intelligent monitoring module is arranged to detect whether the steel wire rope deviates or not, whether rope groove abrasion exceeds the abrasion safety range or not and whether the moving speed of the steel wire rope exceeds the linear speed standard value or not in the using process of the traction wheel, and the microcontroller outputs a driving control instruction to the action protection assembly to conduct emergency action protection. The purpose of integrating monitoring, warning and protection is achieved, the traction sheave has the protection function, and the intelligence of the traction sheave is improved.
