The invention provides a trackless type electric portal frame. The trackless type electric portal frame comprises a transverse beam, stand columns and base plates. An electric block is arranged on the transverse beam; the lower portions of the stand columns are connected with the base plates through first connecting pieces, and the upper portions of the stand columns are connected with the transverse beam through second connecting pieces; the two ends of the front face of each base plate are each provided with a driving wheel, and the two ends of the rear face of each base plate are each provided with a driven wheel; and each driving wheel is provided with an electric walking device. The trackless type electric portal frame has the beneficial effects that universal wheels are arranged on the base plates of the portal frame, and the electric walking devices are arranged on the driving wheels; trackless automatic walking of the portal frame can be achieved by controlling a motor, and the portal frame does not rely on definitive tracks on the ground and manual pushing any more; and the portal frame is simple in structure and convenient to use, manpower and material resources are greatly saved, the working efficiency is improved, and the cost is reduced.
