Auxiliary steel ladder structure of transformer

The utility model relates to an auxiliary steel ladder structure of a transformer, and belongs to the technical field of transformer manufacturing equipment. According to the technical scheme, a hole (22) and a notch (21) are formed in a connecting pipe (2), the diameter of the hole is matched with that of round steel (3), the round steel and the connecting pipe are vertically welded through the hole, and a connecting rod (1) is welded to the top end of the connecting pipe (2) through the notch (21); a first round hole (11) is formed in the connecting rod (1), the first round hole is matched with the fastening piece, and the connecting rod (1) is connected to the lower end of the original steel ladder (5) through the fastening piece (4). The auxiliary steel ladder has the beneficial effects that the auxiliary steel ladder is connected below the original steel ladder through the fastener, so that the problem that the lowermost end of the conventional steel ladder cannot be lower than the lower surface of a tra
