Servo frame of rake arm pipe

The utility model discloses a rake arm pipe servo frame which comprises a base, the base is movably connected with a first assembly, the first assembly comprises a first through pipe, the first assembly is movably connected with a second assembly, the second assembly comprises a second through pipe, the second assembly is movably connected with a third assembly, and the third assembly comprises a third through pipe. A pipeline can sequentially penetrate through the first through pipe, the second through pipe and the third through pipe, the first through pipe, the second through pipe and the third through pipe can move along with the pipeline, and a cable and the pipeline which need to be connected sequentially penetrate through the first through pipe, the second through pipe and the third through pipe and then are connected with a rake arm pipe. Meanwhile, due to the fact that all the components are movably connected, when the drag suction hopper dredger works, the drag suction hopper dredger can move along w
