Column plate longitudinal seam abutting method

Abstract

The invention relates to a column plate longitudinal seam abutting method. The method comprises the following steps: taking a positioning tool, wherein the tool comprises a permanent magnetic lifting jack, a strip-shaped plate is arranged at the front side of the permanent magnetic lifting jack and is higher than the bottom surface of the permanent magnetic lifting jack; fixedly adsorbing the permanent magnetic lifting jack on one side of a column plate longitudinal seam so as to align the strip-shaped plate to the column plate longitudinal seam; inserting a crowbar into a clearance between the strip-shaped plate and a column plate, assembling and positioning the dislocated longitudinal seam by utilizing the lever force of the crowbar and welding the assembled and positioned part; moving the permanent magnetic lifting jack along one side of the longitudinal seam, assembling and positioning the un-welded part again and welding until the overall column plate longitudinal seam is abutted. The column plate longitudinal seam abutting method disclosed by the invention is convenient to operate, time-saving and labor-saving; the overall plate seam needs not to be grinded because an original horse plate is cancelled, the 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 method for butt jointing 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 method for butt jointing of vertical seams of tower plates in view of the above-mentioned prior art. The quality of th...
