The invention provides a welding rolling wheel bracket with low noise and the good supporting effect. Each supporting plate is provided with a double-head driving motor and two pairs of fixing brackets. Two side arc-shaped brackets are arranged on the two sides of each main supporting wheel respectively. Each main supporting wheel is installed between the two corresponding fixing brackets through a rotating shaft penetrating through the middles of the corresponding two side arc-shaped brackets. Two rotating shafts at the two ends of each double-head driving motor are each provided with a driving gear. One end of the rotating shaft of each main supporting wheel is provided with a driven gear which is engaged with the corresponding driving gear. Each main supporting wheel corresponds to one pair of side supporting wheels. Each side supporting wheel is fixed between the ends of the two corresponding side arc-shaped brackets through a rotating shaft. Each end of the rotating shaft of each side supporting wheel is provided with a limiting piece. The bottom of each supporting plate is provided with a bottom frame. The two supporting plates are connected through a connecting plate. The bottom of each supporting plate is provided with damping suckers. According to the welding rolling wheel bracket, the double-head driving motors are adopted for driving rolling wheels at the two ends, in this way, the cost is low, and the supporting effect is good; in addition, damping cushions are arranged at the bottom, so that the damping effect is obvious.
