After the transportation of the lengthened bulb-shaped steel 92 is completed, the clamping plate 74 is far away from the lengthened bulb-shaped steel 92, so that the lengthened bulb-shaped steel 92 is separated from the limiting frame 73, the positioning trolley 7 is lifted upwards, the positioning trolley 7 is withdrawn, and the transportation of the next lengthened bulb-shaped steel 92 is prepared.

According to the flat bulb steel lengthening method, the two fed flat bulb steels 91 are cut to form a crevasse, then are lengthened through welding, then the lengthened flat bulb steels 92 are transported to a flat bulb steel installation station, and the lengthened flat bulb steels 92 are directly installed. The flat bulb steel is not required to be cut, processed and welded to be lengthened at a flat bulb steel installation station, so that the time is saved, and the ship building efficiency is improved.
