| Zusammenfassung: | A double-reel hydraulic oil pipe transportation device relates to a hydraulic power transmission device. The double-reel hydraulic oil pipe transportation device comprises a spindle, an oil transportation pipeline part and an oil return pipeline part, wherein a high-pressure oil pipeline and an oil return pipeline, which are used for being connected with an external hydraulic power source, are arranged in the spindle; the oil transportation pipeline part transports high-pressure hydraulic oil of the hydraulic power source to a hydraulic drive unit via an oil transportation channel arranged in the oil transportation pipeline part and communicating with the high-pressure oil pipeline and an oil transportation hose wound around the oil transportation pipeline part; and the oil return pipeline part enables hydraulic oil of the hydraulic drive unit to flow back to the hydraulic power source via an oil return channel arranged in the oil return pipeline part and communicating with the oil return pipeline and an oil |
