Background
In recent years, the bridge construction industry in China is developed rapidly, and a large-section hoisting technology of steel box girders is adopted in the construction of some super-large bridges. For the construction of offshore bridges, the construction period at sea should be reduced as much as possible, the risk of offshore construction is reduced, and the economy of the construction scheme is improved. At the present stage, because the dead weight of the marine large-section steel box girder is large, in order to ensure that the steel box girder does not deform during hoisting, a truss type or a pressure bar type hoisting tool is generally adopted to distribute the weight of the steel box girder to a plurality of hoisting points and enable the hoisting points to bear the force only in the vertical direction, so that the hoisting points are prevented from being stressed by horizontal split force during hoisting to extrude and deform the steel box girder bridge deck. The truss type lifting appliance is relatively high in structural rigidity, large in self weight, high in self height, and high in cost due to the fact that a crane ship with a larger lifting height needs to be selected or a steel wire rope with higher strength needs to be adopted to meet the requirement of lifting height. At present, a pressing rod type lifting appliance commonly adopted mostly adopts a form of connection of a pulley set for ensuring the stress requirement of each lifting point, a steel wire rope is easy to separate from a sliding groove under the condition that a steel box girder has longitudinal and transverse slopes, and the steel wire rope needs to be replaced when the gradient changes to influence the construction period.
