The utility model discloses a movable type bridge crossing device for 220 kV GIS equipment. The movable type bridge crossing device for the 220 kV GIS equipment comprises four stand columns, the middles of the four stand columns are connected with the two ends of fixing rods on the two sides of a flat ladder respectively through corner connectors, the two stand columns at the two ends are respectively connected with an inclined ladder through an inclined connecting plate, the upper ends of the two inclined ladders correspond to the two ends of the flat ladder respectively, inclined railings are arranged on each inclined ladder, horizontal railings are arranged at the upper ends of the stand columns and are fixedly connected with the stand columns through corner connectors, and the inclined railings are fixedly connected with the inclined ladders through supporting rods. The movable type bridge crossing device for the 220 kV GIS equipment lowers the difficulty for the personnel of a transformer substation to arrange safety measures and reduces the workload of the personnel of the transformer substation to arrange the safety measures; meanwhile, the potential danger that the personnel walk in wrong operation intervals in the overhaul operation is avoided, a sole channel is ensured, and the reliability of the field safety measures is ensured. The field safety disclosure visualization is achieved, and the level of field safety management is improved.
