Column plate longitudinal seam abutting and positioning tool

Abstract

The invention relates to a column plate longitudinal seam abutting and positioning tool and belongs to the technical field of shipbuilding and ship repairing. The column plate longitudinal seam abutting and positioning tool comprises a permanent magnetic lifting jack (6); a strip-shaped plate (7) is arranged at the front side of the permanent magnetic lifting jack (6) and is higher than the bottom surface of the permanent magnetic lifting jack (6). By adopting the column plate longitudinal seam abutting and positioning tool disclosed by the invention, a horse plate needs not to be sintered or cut and an iron needle needs not to be knocked during assembly of a plate seam, the permanent magnetic lifting jack needs to be moved, and the dislocated plate seam is assembled and positioned by utilizing the lever theory of a crowbar and the attraction theory of the permanent magnetic lifting jack, so time is saved, labor is saved, and welding materials are also saved; besides, no grinding is needed because the overall plate seam is free of a burst seam, so the labor intensity of a worker is alleviated, the surface quality of the plates at the two sides of a welding seam is guaranteed, and the appearance quality is considerably improved after painting is finished.

Description

technical field [0001] The invention relates to a butt joint positioning tool for longitudinal seams of tower plates, which belongs to the technical field of ship repairing and building. Background technique [0002] The vertical seam butt joint of the traditional tray adopts horse plate, iron pin and hammer for assembly and positioning (see figure 1 ), which has many disadvantages. First, it takes time. Second, there are flaws on the surface of the tower plate that need to be polished. Third, the quality of the final painted surface of the tower tube is poor. With the increasing production tasks of the business department and the increasingly picky appearance quality of customers, the existing technology can no longer meet the production requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a butt joint positioning tool for the longitudinal seam of the tower plate according to the above-mentioned prior ...
