Device for solving problem of local differential settlement of pipeline through two rotating compensation devices

The invention discloses a device for solving the problem of local differential settlement of a pipeline through two rotating compensation devices. The device comprises a first pipeline body (3) and a second pipeline body (5). The first rotating compensation device (1) is mounted on the first pipeline body, and the second rotating compensation device (2) is mounted on the second pipeline body. The axes of the first pipeline body and the second pipeline body are parallel, and the axes of the first rotating compensation device and the second rotating compensation device are parallel. The first pipeline body is connected with the second pipeline body through a short pipe (4). By arranging a heating pipeline in the mode, the problem of differential settlement of the pipeline can be effectively solved; and through rotation of the rotating compensation devices, the short pipe and a bend form a force arm, accordingly, free rotation in a pipeline constraint range is achieved, and free settlement of the two pipeline bo
