Pipeline splicing auxiliary device

The utility model relates to an auxiliary device for pipeline splicing. The auxiliary device for pipeline splicing comprises a chain block, a movable pulley and a turntable, the movable pulley is fixed to the pipeline through a rope, and a gear disc capable of rotating is arranged in the movable pulley. One end of the chain block is fixed on the other pipeline, and the other end of the chain block bypasses the movable pulley inner gear disc; the rotating disc is arranged on one side of the movable pulley and fixedly connected with the gear disc in the movable pulley, and the gear disc can be driven to rotate by rotating the rotating disc. In the installation process of engineering pipelines, constructors can drive the gear disc in the movable pulley to rotate by rotating the rotary disc, tension the chain block through the gear disc and enable two sections of pipelines to move relatively for splicing through the chain block, so that the situation that the chain block is pulled manually in the pipeline splicin
