Embodiment Construction

[0009] Hereinafter, a method for processing a plate row for leveling a hull of the present invention will be described.

[0010] First, in the vicinity of the paneling station, sort out a flat cement site that is greater than or equal to the size of the panel row. According to the maximum plate row size of the hull parallel to the mid-body part, the plate row to be rectified after tailor welding is laid on the site;

[0011] Then, roll the road roller 1 (two or three wheels, preferably two-wheel type) for general road construction along the weld bead direction of the plate row to be straightened after tailor-welding, generally one round trip. Meet the technical requirements of flatness.

[0012] Figures 1 and 2 show the schematic plan view of the two-wheeled road roller when rolling back and forth. Figure 1 shows the roller 1 rolling along the direction of the straightened plate row weld bead, and Figure 2 shows the road roller 1 rolling along the straightening process. The ...

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 leveling a ship hull. Background technique [0002] The deck, side plate, outer bottom plate, inner bottom plate and inner and outer wall plates of superstructures in the parallel mid-body part of the hull are all composed of single strake (generally t×8000×1600mm, namely: thickness×length×width), which is 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 and the flatness of the plate row is affected. 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 calibrating and rolling machine (with a width of 6-12 meters) is about 6 to 10 million yuan, and it needs to have a board entry area, a rolling machine working area and a board exit ar...
