The portal beam stretches across the deck and can move on the deck in the direction of a main beam of the ship. The bottom of the trolley frame is arranged on a cross rod of the portal beam and can axially move along the cross rod; the lifting mechanism comprises a plurality of telescopic assemblies which are distributed below the two sides of the trolley frame. The top of the balance beam is connected with a plurality of telescopic assemblies, the balance beam is hung below the trolley frame and the cross rod, and a clamping jaw is fixed to the balance beam. Compared with the prior art, the gantry beam and the trolley frame are matched to realize XY two-dimensional plane operation on a deck, and the trolley can cover the whole working plane; meanwhile, the transfer trolley is further provided with the lifting mechanism, so that XYZ thre
