The invention provides a pipeline lifting appliance which comprises a lifting rope, a base body, a lifting ring, an adjusting wheel, an adjusting wheel shaft used for fixing the adjusting wheel, pressing wheels, pressing wheel shafts used for fixing the pressing wheels and lifting hooks arranged on the lifting rope. The pressing wheel shafts and the adjusting wheel shaft are arranged on the base body. The pressing wheels are located above the adjusting wheel. The lifting rope penetrates through a U-shaped groove in the periphery of the adjusting wheel in the circumferential direction. The upper side of the lifting rope is in contact with the pressing wheels. The lifting hooks are arranged at the two ends of the lifting rope respectively. The base body is of a U-shaped structure with an opening facing downwards. An annular groove is formed in the periphery of each pressing wheel. A self-lubricating bearing is arranged between each pressing wheel and the corresponding pressing wheel shaft. A self-lubricating bearing is arranged between the adjusting wheel and the adjusting wheel shaft. According to the pipeline lifting appliance, the structure is simple, the fabrication cost is low, the balance of a lifted pipeline can be adjusted automatically through the adjusting wheel, the pressing wheels used for preventing the lifting rope from disengaging are further arranged, and the reliability and safety are high.
