The invention relates to a method for continuously hoisting rolling mill housings by hydraulic pushing and lifting. The method comprises the following steps: a traveling crane is used as a platform, the traveling crane is equipped with a makeshift trolley (14) which has the same span as that of a trolley of the traveling crane, then a hydraulic lifter (11) is positioned on the makeshift trolley,a movable support (9) is connected below a main beam (17) of the traveling crane so as to increase the loading capacity of the main beam of the traveling crane, a hydraulic propeller (12) is arrangedon the ground, then the mill housings (18) are lifted and hoisted to the mounting position by the traveling crane, the makeshift trolley, the hydraulic lifter and a hoister (13), and the mill housingmoves freely in the vertical and horizontal directions, thus realizing continuous hoisting of a plurality of the milling housings in place. The method has the advantages of being capable of realizingthe continuous hoisting of the milling housings, short construction period, simple hoisting process and easy operation, thus improving construction safety factor and lowering construction cost. The method is especially suitable for realizing the continuous hoisting of the milling housings under the condition that lifting capacity of the traveling cranes in a factory building can not meet the requirement of mounting the mill housings.

The invention discloses a floating hoisting protection device for a transport ship, which comprises a synchronous lifting unit and a damping support unit; the synchronous lifting unit is arranged at the center of gravity of the fan blade, and the synchronous lifting unit raises the fan blade by a certain distance; the damping support unit is arranged at the fan blade The tail end of the blade supports the suspended tail of the fan blade. The fan blades are raised by the synchronous lifting unit, and the suspended tail of the fan blades is supported by the damping support unit. The damping support unit can not only reduce the deformation of the fan blades due to its own weight, but also prevent the fan blades from colliding with the ship during hoisting. Plate contact collision can also absorb the force of the fan blades caused by the turbulence of the sea surface. The above scheme directly lifts the fan blades from the transport ship, which saves the process of hoisting and transshipment, simplifies the hoisting process, improves the hoisting efficiency, and prevents the fan from The blades are damaged during the hoisting process, which eliminates potential safety hazards and reduces the bumping force of the fan blades.
