When repairing the running pipeline, it is necessary to first seal the ruptured part of the pipeline with a sealing device, and then carry out maintenance work.

[0003] The existing plugging devices are unable to adjust the position of the plugging block according to the rupture of the pipeline. For example, the pipeline plugging device for urban gas projects disclosed in utility model patent CN214305895U is not fixed in position, so it is necessary to adjust the clamping position of the fixed plate first so that the plugging block can be realigned with the rupture of the pipeline before plugging. This operation is cumbersome and inconvenient, and when it is not needed, the plugging device has a complex structure and occupies a large area.

[0004] In addition, if there are more than two ruptures in one section of the pipeline, the existing plugging device cannot plug all the ruptures at the same time and can only plug them one by one, resulting in low maintenance efficiency. Utility Model Content
