The invention discloses a single double-roller engine driven winching device which comprises a supporting frame. A first roller and a second roller are mounted on the left end surface of the supporting frame and are placed in parallel. Fasteners are mounted on the outer side of the supporting frame. A supporting plate is arranged on the lower left end of the supporting frame, and a winching rope brake rod is mounted on the surface of the supporting plate. A reduction gearbox is mounted on the surface of the middle of the supporting frame, and an engine is mounted on the right end surface of the supporting frame. According to the engine driven winching device, the safety coefficient in the weight lifting and falling process is improved, the phenomenon that a winching rope slips always is comprehensively improved especially under the condition that the single double-roller engine driven winching device is used in the previous tower pole assembly or wire stringing construction process, and the problem that the winching rope fails to achieve winching is solved. The safety of hoisted pieces lifting and falling in the iron tower assembly process is guaranteed, and meanwhile the safety risk of personnel controlling the winching rope behind the winching device is reduced.
