Embodiment Construction
[0019] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0020] Such as Figure 1-2 , the hull can be divided into several sections according to the actual situation. In this embodiment, the hull is divided into three general sections: bow, midship and stern. Shift to the stern general section 3, and then shift the bow general section 1 to the midship general section 2.
[0021] In this embodiment, the method is to arrange 32 sets of 226t (tons) hydraulic trolleys 13 respectively under the general section of the ship to be moved, and realize the displacement between the general sections through synchronous jacking and synchronous displacement, so as to achieve the purpose of displacement , the weight of the large total section to be moved is ≤6000 tons, and the gap between the total sections is ≤200mm. In the following, the method of shiftin...

The invention discloses a ship block displacement method which comprises the following steps: S1. a plurality of displacement devices are distributed in areas at the lower part of a block to be displaced, and the jacking platforms of the displacement devices are pre-jacked so as to contact with the bottom of the block to be displaced; S2. the displacement devices synchronously jack up the block to be displaced so as to isolate the block to be displaced from a docking block below the block to be displaced at preset distance, wherein, the preset distance meets the displacement requirement of the block to be displaced; S3. the jacking platforms drive the jacked block to be displaced to move forwards the other block, wherein, the block to be displaced moves along the direction of the center line of a ship in the displacement process; and S4. after the block to be displaced moves to a preset position, the jacking platforms synchronously descend so as to drive the block to be displaced to drop to the docking block synchronously. The ship block displacement method can greatly shorten ship construction period and shift a great amount of outfitting and coating operation to the platforms without affecting construction of other ships owing to short time of occupying a dock.
Description
technical field [0001] The invention relates to a method for displacing a large total section, in particular to the displacement of the midship or bow large general section of a bulk carrier and an oil tanker with a weight of the large total section less than 6,000 tons. Background technique [0002] With the rapid development of science and technology in the world, the design technology, manufacturing technology and management technology of shipbuilding are also constantly advancing. Modern shipyards not only apply individual advanced technologies, but successfully integrate ship design, production, precision Closely combined, under the new high-efficiency production mode, the advantages of the advanced shipbuilding method have been fully utilized, and obvious benefits have been achieved. It can be said that the method is one of the important symbols of a modern shipyard. [0003] When manufacturing the hull in the prior art, each general section is directly built in the do...
