The technical scheme of the invention is further explained by combining the attached drawings and the embodiment. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.
In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
In order to reduce the operation difficulty in the stage of sectional carrying and folding, the period of ship construction is shortened. As shown in fig. 1, the invention provides a process method for controlling the carrying precision of ship segments. The process method for controlling the carrying precision of the ship section comprises the following steps:
s1, after the ship is built in a segmented mode, measuring the segments to obtain segmented three-dimensional data;
s2, comparing the three-dimensional data with the design data to form a segment precision adjustment report;
s3, correcting the segments according to the segment precision adjustment report, so that the manufacturing precision of the segments meets the requirement of carrying operation;
s4, drawing a butt joint line at the butt joint position of the segments;
and S5, carrying the adjacent segments, aligning the involution lines between the two adjacent segments, and completing the involution positioning between the adjacent segments.
Through the mode, the work that originally needs just to be accomplished in the carrying stage is migrated to the level land stage in a large number and is accomplished, the production environment has been optimized by a wide margin, make the carrying stage directly can to closing and assemble, need not to adjust the segmentation in the high altitude, through drawing to establish to closing the line and make the operation process directly perceived, convenient, quick, can promote the operating efficiency who carries the location by a wide margin under the prerequisite of guaranteeing the operation precision, reduce the segmentation and carry the operation degree of difficulty that closes the stage, shorten the cycle of shipbuilding, and facilitate for the operation of other work types.
Further, in step S1, the segment is measured with a total station. The Total Station, i.e. the Total Station Electronic distance meter (Electronic Total Station), is a high-tech measuring instrument integrating light collection, mechanical measurement and electrical measurement, and is a surveying instrument system integrating horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measurement functions. The manual optical micrometer reading is replaced by automatic recording and displaying of the reading, so that the angle measuring operation is simplified, and the reading error can be avoided. The requirement for measuring segmented data can be well met.
Further, in step S2, the segmented three-dimensional data is compared with the segmented data corresponding to the designed ship model, so as to obtain a segmented accuracy adjustment report. By the method, the accuracy of the obtained segmentation accuracy adjustment report can meet the requirement by using the designed segmentation model to correspond to the segmented entity.
And further, comparing the segmented three-dimensional data with the data of the corresponding segments in the designed ship model by using data processing software. The data processing software can improve the speed and the precision of data processing, prevent larger errors caused by manual processing, and provide accurate data for the adjustment of the segmented entities.
Further, in step S2, the segment precision adjustment report is generated into a paper version. The segmentation precision adjustment report form through generating the paper version is convenient for use at the job site, and at the job site, the constructor is every to a data adjustment, can utilize the stroke to fall, and the constructor of being convenient for in time accurately masters the construction progress, avoids because not colluding the construction chaos that causes of data to the cycle of extension construction.
Further, in step S3, the modifying the segment includes cutting the margin of the segment. And cutting redundant parts to enable the segmentation to meet the precision requirement of involution and assembly. Specifically, the margin of the segment is cut by the flame cutting. The high-heat flame cutting steel plate is produced by mixing oxygen and acetylene or propane in the flame welding cutting process, and pipelines can be arranged according to the on-site requirements, so that the construction flexibility and the on-site adaptability are greatly improved.
Further, in step S3, the correcting the segment includes replacing the slab at the starved position and adjusting the position where the deviation exists. By adjusting the segments, the segments can meet the requirements of involution and assembly.
Further, in step S4, a butt line is scribed at the butt position of the segments using paint. The butt joint line is arranged by painting, so that the butt joint line is not easily smeared during construction, when the sections are butt jointed, a constructor can conveniently and visually observe, the difficulty of butt joint and assembly is reduced, the butt joint efficiency is improved, and the building speed of the ship is accelerated.
And further, carrying the subsections by using a gantry crane. The gantry crane can meet the requirement of large-scale sectional hoisting and ensure that the closing work is carried out smoothly.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
