The utility model relates to an auxiliary transportation device for upright construction of a jacket, which comprises a load-bearing base, a support artificial leg is coaxially arranged on the load-bearing base, a plurality of reinforcing rib plates are symmetrically arranged on the
peripheral side of the support artificial leg, the top end of the support artificial leg is fixedly connected with a jacket leg, and the bottom of the support artificial leg is fixedly connected with the load-bearing base through the reinforcing rib plates; the two sides of the bearing base are fixedly connected with
load sharing structures to form an H-shaped base, and the bearing base is loaded on the module transport vehicle through the
load sharing structures to vertically transport the jacket; according to the device, the supporting
artificial legs are fixedly connected with the jacket legs and matched with the reinforcing rib plates to achieve high connection strength, meanwhile, the H-shaped base is high in strength, one tool can be loaded on two transport vehicles at the same time, the weight of the jacket is shared, and the requirements for upright construction and transportation of the four-leg jacket with the large weight are met.
