[0002] A pipeline is a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids, or fluids with solid particles. After the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part, or can also be transported by the pressure or gravity of the fluid itself. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations. It is necessary to use the lifting tools of a crane to hoist and load the pipeline. However, in the prior art, during the hoisting process of the pipeline, generally, multiple pipelines need to be bundled together by ropes, and the bundled pipelines are lifted by hanging the steel wire rope in the middle part of the pipeline with a hook. However, this hoisting method has certain risks. If the pipelines are not firmly bundled, they are likely to become loose and fall. When hoisting the pipeline with a single crane hook, the pipeline is prone to deformation and other technical problems, and it is also prone to swing and vibration. Therefore, in the prior art, it is inconvenient to hoist and transport the pipeline. Content of the Utility Model

Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. The driving mechanism includes several horizontally arranged and coaxially arranged rotating shafts. The parts of each rotating shaft are connected by a coupling, and the rotating shaft can be rotatably transferred to the support frame. The support frame is provided with an electric motor. The power output shaft of the motor is connected to the rotating shaft. The rotating shaft is provided with a drum for retracting and releasing the wire rope, which is arranged one by one corresponding to the support plate. The upper end of the wire rope is connected to the drum. When the motor is started, the motor drives the rotating shaft to rotate, and the drum on the rotating shaft is wound around the wire rope to realize the retraction and release of the wire rope.
