Protective mechanism for high-altitude erection of pipeline

The utility model relates to the technical field of pipeline erection, and discloses a pipeline high-altitude erection protection mechanism which comprises a cloth bag frame, U-shaped plates are fixedly connected to the left side and the right side of the cloth bag frame correspondingly, a mounting mechanism is arranged outside the cloth bag frame, and adjusting assemblies are arranged on the front side and the rear side of the cloth bag frame correspondingly. Through the design of the mounting mechanism, when different fire-fighting pipelines are spliced, two groups of first arc-shaped plates and second arc-shaped plates can be respectively placed outside two different pipelines, and are tightened through bolt rods, so that the first arc-shaped plates and the second arc-shaped plates are fixed outside the pipelines after being matched; the length of the whole cloth bag frame can be adjusted by pulling the distance between the two U-shaped plates so that the cloth bag frame can meet the requirements of differ
