Ship body segment butt joint cutting device for segmented ship body

Abstract

The invention relates to the technical field of ship construction, in particular to a ship body section butt joint cutting device which comprises a first guide rail detachably connected to a section ship body at the edge of a butt joint, and the extension direction of the first guide rail is perpendicular to the length direction of a first ship body section (changed to be parallel to a welding seam, and some sections are folded left and right). The first guide rail is provided with a walking mechanism, the walking mechanism is provided with a first cutting piece and a second cutting piece, the first cutting piece and the second cutting piece are arranged in a spaced mode, and the walking mechanism moves on the first guide rail so that the first cutting piece and the second cutting piece can cut the to-be-folded end of the first ship body section and the to-be-folded end of the second ship body section correspondingly. Due to the fact that the distance between the first cutting piece and the second cutting piece is fixed, it can be guaranteed that the widths of butt joints of ship body sections are completely consistent at all the positions, the cutting efficiency is high, and the high-precision ship body folding welding requirement can be met.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a segmented butt seam cutting device for a hull. Background technique [0002] During the construction of a large ship, the hull needs to be divided into several sections for construction. After the construction of the sections is completed, the adjacent sections are welded to realize the closure of the hull sections. Such as figure 1 As shown, in order to ensure the accuracy of the hull construction, when the hull is constructed in sections, it is necessary to reserve a certain machining allowance at the closing mouth; The machining allowance is used to ensure that the butt joint width of adjacent hull sections is uniform. [0003] At present, when the hull sections are closed, it is necessary to cut the repair allowances at the closing openings of two adjacent hull sections respectively. After the repair allowances are cut, it is difficult to ensure that the width of the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a hull segment butt seam cutting device. The technical problem to be solved by the hull segment butt seam cutting device of the present invention is: the existing hull segment cutting device cannot guarantee the alignment of the hull segment. The seam width is uniform in all parts, and it is difficult to meet the requirements of high-precision hull closing welding
