Problems solved by technology

At this stage, most of the sections need to be transported to the section yard after being built on the tire frame after being hoisted and transported and put on the door frame to be outfitted / assembled / lifted. If the sections are simply stacked in this process It is easy to cause deformation. If it is not adjusted in time, some outfitting parts (pipes, etc.) installed in the subsequent process will objectively strengthen the deformation, resulting in difficult adjustment in the general assembly stage and a large amount of rework, which will adversely affect the hull construction. Therefore, it needs to be corrected by a horizontal correction device

Embodiment 1

[0029] A horizontal stacking correction device for hull sections, comprising a correction main body 1 and a correction accessory 2 that are not connected to each other, both the correction main body 1 and the correction accessory 2 can be fixed on the outer plate 3 of the hull section, and the hull sections are stacked on the mast 4, such as figure 1 As shown, a level 12 is provided at the end of the calibration main body 1 away from the outer panel 3, and a scale 22 is provided at the end of the calibration accessory 2 away from the outer panel 3, as figure 2 As shown, the laser beam emitted in the spirit level 12 is projected on the scale 22, as image 3 As shown; the calibration main body 1 and the calibration accessory 2 are set independently, and can be placed in different positions on the outer plate, not only for the segment where the outer plate 3 is flat, but also for the non-horizontal segment or total segment of the outer plate 3 In addition, the correction main b...

Embodiment 2

[0035] The hull section horizontal stacking correction device of this embodiment is basically similar to the structure in embodiment 1, including the correction main body 1 and the correction accessory 2 which are not connected to each other, and both the correction main body 1 and the correction accessory 2 can be fixed on the outer surface of the hull section. On the board 3 , a level 12 is provided at the end of the calibration main body 1 away from the outer board 3 , and a scale 22 is provided at the end of the calibration accessory 2 away from the outer board 3 , and the laser beam emitted from the level 12 is projected onto the scale 22 .

[0036] The difference is that the specific size of the calibration body 1 and the calibration accessory 2 is not limited, and the way of fixing the calibration body 1 and the calibration accessory 2 on the outer plate 3 is not limited; the calibration body 1 arranged at different positions on the hull section can be implemented Cooper...

Embodiment 3

[0038] A method for correcting horizontal stacking of hull segments, which is implemented using the segmented horizontal stacking correction devices for hulls in Embodiment 1 and Embodiment 2, comprising the following steps,

[0039] Step 1, at first select the datum point of the hull segment and a plurality of reference points of different orientations;

[0040] Step 2, attach the calibration body 1 to the reference point, and attach the calibration accessory 2 to the reference point;

[0041] Step 3, the laser beam emitted by the level 12 on the calibration main body 1 is projected onto the scale 22 of the calibration accessory 2, and the readings of each scale 22 are adjusted to the same reading through sleeper adjustment.

[0042] Both the datum point and the reference point are set at the position of the strong structure, which is the intersection point of the floor, girder or wall plate of the hull segment and the plate width. The position of the strong structure is not ...

Abstract

The invention discloses a horizontal ship body section stack correcting device and method, and relates to the technical field of shipbuilding. The horizontal ship body section stack correcting device comprises a correcting main body and correcting accessories; the correcting main body and the correcting accessories are not connected with each other, and the correcting main body and the correcting accessories can be fixed to outer plates of ship body sections; level gauges are arranged at one ends, far away from the outer plates, of the correcting main body; dividing rulers are arranged at the ends, far away from the outer plates, of the correcting accessories; and laser beams ejected from the level gauges can be projected to the dividing rulers. The horizontal ship body section stack correcting method can correct the level degrees of different positions by adjusting the values of the dividing rulers in different directions to be identical through the correcting device. By means of the horizontal ship body section stack correcting device and method, the structure is simple, operation and carrying are convenient, the adjusting accuracy is high, the application scope is wide, and the reworking amount of the next process can be reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a device and method for correcting horizontal stacking of hull sections. Background technique [0002] The hull segment is a partial hull structure composed of parts and components of the hull, and is an intermediate product that forms the overall hull. The use of segmented assembly and welding technology allows each segment to be constructed in parallel, thereby shortening the shipbuilding cycle and improving production efficiency. At this stage, most of the sections need to be transported to the section yard after being built on the tire frame after being hoisted and transported and put on the door frame to be outfitted / assembled / lifted. If the sections are simply stacked in this process It is easy to cause deformation. If it is not adjusted in time, some outfitting parts (pipes, etc.) installed in the subsequent process will objectively strengthen the deformation, result...
