Embodiment Construction

[0009] The processing method of a flat row of hulls of the present invention will be described below.

[0010] First of all, a flat cement site larger than or equal to the size of the board column is sorted out near the paneling station. According to the maximum plate row size of the parallel mid-hull part of the hull, the plate rows to be rectified after tailor welding are laid flat on the site;

[0011] Then, roll the general road roller 1 (two-wheel or three-wheel, preferably two-wheel) along the weld bead direction of the plate column to be rectified after tailor welding, and generally go back and forth once. Meet the technical requirements of flatness.

[0012] figure 1 , 2 Shown is a schematic plan view of a two-wheeled road roller rolling back and forth. figure 1 For the road roller 1 to carry out rolling along the direction of the plate column welding bead of the rectification treatment, figure 2 Shown is the case where the roller 1 is rolling along the direction...

Abstract

The invention provides a method for flattening the plates of ship, which comprises following steps: first, preparing a flat cement ground larger than the plates near the assemble position, and arranging the plates on it; then, rolling the plates with road roller along the soldering channel, while one time can reach the demand. The invention has the advantages that: 1, selecting the road roller to reach the same effect of correct rolling device, and better than the water flattening, which can reduce the cost as 6-10 million yuan; 2, the road roller can be moved to another place to avoid possessing area; 3, the road roller uses diesel oil as power, to reduce the oil consumption; 4, the road roller can be operated by one driver, while the rolling device need more people; 5, the maintenance of road roller is easier than the rolling device.

Description

technical field [0001] The invention relates to a processing method of a plate row for flattening a hull. Background technique [0002] The deck, side plating, outer bottom plating, inner bottom plating and superstructure inner and outer wall panels of the parallel mid-body part of the hull are all made of single strakes (generally t×8000×1600mm, that is: thickness×length×width), composed of Submerged arc automatic welding or manual welding, etc. are spliced ​​into plates. Due to the thermal influence of welding, the weld bead area is deformed, which affects the flatness of the plate row. There are two traditional methods: one is to use a nine to eleven roller leveling machine for overall correction to eliminate welding stress and deformation. The investment of this large-scale leveling roller leveling machine (with a width of 6 to 12 meters) is about 6 to 10 million yuan, and it needs to have a plate entry area, a roll leveling machine work area and a plate exit area, whi...
