A boom 5 is mounted on top of the lifting column 4, and a gantry 6 is hinged to the end of the boom 5. The gantry 6 lifts the mud-water outlet pipe onto the platform of the transport vehicle 2. The transport vehicle 2 travels on a track 1, powered by rail-based electricity. The lifting equipment on the transport vehicle 2 handles the lifting, dismantling, and relocation of the mud-water pipes. The lifting equipment lifts the mud-water pipe, raises it, and then transfers it into the transport vehicle 2 via a traveling mechanism.

[0039] In the preferred embodiment, the lifting column 4 has a hydraulic lifting column body inside. The end of the telescopic rod of the lifting column 4 is rotatably connected to the lower end of the support rod 10, and the upper end of the support rod 10 is connected to one end of the boom 5.

The boom 5 can also be adjusted in height. In a small space, the boom 5 combined with the lifting column 4 can adapt to the rapid dismantling of the mud discharge pipe in different positions.

[0040] In the preferred embodiment, the boom 5 includes two parallel lifting booms 501 and lifting slender booms 502.

The boom 5 is finely adjusted so that the hanger 6 at the end of the movable boom 504 is close to the sludge discharge pipe.

[0054] The third hydraulic cylinder 1203 controls the gripper 12. Multiple third hydraulic cylinders 1203 control the opening of the gripper arm 1204 of the gripper 12. Multiple third hydraulic cylinders 1203 control the gripper arm 1204 to clamp the mud discharge pipe.
