The utility model discloses a pipeline-surrounding
pipe climbing operation
robot which comprises a
pipe climbing
robot body and a lengthwise track, and the
pipe climbing
robot body comprises a vehicle body and wheels. The wheel comprises an inner wheel used for walking on the surface of the track and an outer wheel abutting against the side wall of the track, the
radius of the outer wheel is larger than that of the inner wheel, and the
radius difference between the outer wheel and the inner wheel is smaller than the thickness of the track; a
cantilever is further arranged on the vehicle body in the axial direction of the pipeline to be operated, and an operation clamp is movably arranged on the
cantilever along the
cantilever. The pipe climbing robot has the advantages that the inner wheel walks on the track, the outer wheel is tightly attached to the edge of the track for limiting, the outer wheel does not make contact with the outer surface of the material pipe,
welding seams and pits in the material pipe can be effectively avoided, and it is guaranteed that the pipe climbing robot does not jump when walking, and the pipeline operation quality is not affected. All the devices are stored together through the movable cabinet, so that storage, movement and field operation are facilitated; and a
cutting torch, a
welding gun and the like can be selectively mounted according to operation requirements so as to realize different operations.
