The rudder blade hoisting and centering tool and the hoisting and centering method realize that mechanical equipment replaces manual chain block operation, welding hanging codes, welding top codes and chain block operation are omitted, the designed and manufactured rudder blade hoisting and centering tool is suitable for rudder blade hoisting and centering operation, when the rudder blade hoisting and centering tool is used, the hoisting and centering tool is hoisted to the site, the rudder blade is installed in a clamping device of the tool, the rudder blade is clamped and fixed, and then the crane is connected with a hanging code of a hoisting support frame of the tool, so that the rudder blade hoisting operation is realized, after the rudder blade is hoisted basically in place, the rudder blade is centered by adopting a centering adjusting device, the hoisting and centering integrated operation is realized, the welding hanging code, top codes and other operations are replaced, and the purposes of improving the production efficiency, guaranteeing the hoisting safety and quality, reducing the production cost and reducing the labor intensity are achieved.
That is, when using, hoist and mount centering frock handling to scene to install the rudder blade in the clamping device of frock, and press from both sides tight rudder blade, adopt the loop wheel machine to be connected with the hoist and mount hanging bracket's hoist and yard, thereby realize the hoist and mount operation of rudder blade, hoist and mount basically in place after, adopt centering adjustment device to carry out centering operation to the rudder blade, realized the integration of hoist and mount centering, utilize the hoist and mount centering device of design preparation, can high-efficient and safe with the rudder whole hoist deck face, and can realize that the installation position is the hull cabin in front, the top is upper ship cabin, under the circumstances that installation height space severely receives the restriction, hoist the rudder whole into the installation position, and can realize centering function, operation platform station people carry out the function of construction operation. The welding lifting device replaces the operations of welding lifting codes, lifting codes and the like, and achieves the purposes of improving production efficiency, guaranteeing the safety and quality of lifting, reducing production cost and reducing labor intensity.
The present invention is not limited to the above embodiments, but is capable of modification and variation in all aspects, including those of ordinary skill in the art, without departing from the spirit and scope of the present invention.
