Method for rapidly detecting accuracy of position seaming in shipbuilding process

Abstract

The invention discloses a method of rapid detection of precision of the position and closure in the process of ship building, which is mainly used to detect the structure and the closure precision of block assembly, and the steps include: before the closure, presetting an assembly position line which is used for ensuring the position of closure on to-be-assembled plates or a truss; before position closure, arranging an another reference line parallel to the assembly position line on one side of the assembly position line on assembled plates or the truss via equidistance; when positioning to assemble, detecting the location precision of the reference line. The invention increases the precision and speed of the block assembly and position closure through the arrangement and application of the reference line (check line), thereby reducing the workload of trimming. Experiments have proved the invention, such as that in the sectioned position closure of vertical wall and horizontal wall of each ship body, the hoisting time of the method is saved by nearly one hour, and the trimming rate of 60% in the existing implementing method is reduced to 20%.

Description

technical field [0001] The present invention relates to the process of positioning and closing in the shipbuilding process, and more specifically, relates to the improvement of the detection / calibration process in the process of positioning and closing. Background technique [0002] In the process of ship construction, if the baseline (inspection line) is not set in advance, it will bring difficulties to the construction of the subsequent process, which is not conducive to ensuring the accuracy and speed of the construction of the subsequent process. During segmental fabrication, the alignment accuracy between the sloping bottom plate and the girder is often out of tolerance. After the transverse wall section and longitudinal wall section are positioned and closed, the inner structure of the transverse wall pier and the longitudinal frame of the bottom section, the longitudinal girders, the inner structure of the longitudinal wall pier and the ribs of the bottom section ofte...

AI Technical Summary

Problems solved by technology

After the transverse wall segment and longitudinal wall segment are positioned and closed, the inner structure of the transverse wall pier and the longitudinal frame of the bottom segment, the longitudinal girder and the inner structure of the longitudinal wall pier and the ribs of the bottom segment often appear out of alignment, and the pier side plate and the bottom The misalignment of segmental longitudinal trusses caused a large number of cutting and repairing phenomena

One of the reasons is that there is a lack of detection of installation inspection lines and angle templates during segmental production, and the lack of segmental positioning reference lines in vertical and horizontal segmental positioning.
