Beschreibung
Zusammenfassung:	The utility model provides a pipeline lifting mechanism which comprises a pipeline clamp, a first lifting mechanism and a second lifting mechanism, and the pipeline clamp is arranged on the outer side of a target pipeline in a sleeving mode. The first lifting mechanism is provided with a first lifting end, the first lifting end is connected with the pipeline clamp, and the first lifting mechanism is used for lifting the target pipeline to a first distance; the second lifting mechanism is provided with a second lifting end, the second lifting end is connected with the pipeline clamp, and the second lifting mechanism is used for lifting the target pipeline to a second distance on the basis of the first distance; the first distance is at least larger than the vertical distance of the second lifting mechanism in the contraction state. According to the pipeline lifting mechanism, the first lifting mechanism serves as a pre-supporting mechanism, then the second lifting mechanism is used for lifting the pipeline to
