The invention discloses a traction device for a wheeled pipeline robot. The traction device comprises a housing and a four-axis differential driving device, wherein a power output bevel gear for driving a driving wheel transmission mechanism is arranged on each of four output ends of the four-axis differential driving device; a pipeline diameter adapting mechanism is arranged above the center between two front driving wheel transmission mechanisms, and another pipeline diameter adapting mechanism is arranged above the center between two rear driving wheel transmission mechanisms. According to the traction device for the wheeled pipeline robot, the rotating speed of four axes can be self-adaptively adjusted according to related running conditions in a pipeline; whether in a transition state or a turning state, the four driving wheels can perform differential movement during turning, thus the problem of movement interference on the traction device of a pipeline robot in obstacle crossing or turning can be solve
