Forming method of balancing weight of solid ballast

Abstract

The invention discloses a forming method of a balancing weight of a solid ballast. The forming method comprises the steps of material preparation, batten hoisting and welding. A forming tool in the hoisting and welding steps comprises at least two vertical supporting rods arranged at intervals, and a supporting plate is vertically arranged above each supporting rod; and L-shaped containing notches are formed in the upper ends of the supporting plates in an inwards-sunken manner, the short arm end points of the containing notches are lower than the long arm end points of the containing notches, the short arm end points of the containing notches are collinear, and the connecting line of the short arm end points is parallel to the connecting line of the long arm end points. According to the forming method, the L-shaped containing notches are formed in the supporting plates, and when battens fall into the L-shaped containing notches due to the self-gravity of the battens, alignment of the side faces of the stacked battens and the opposite side edges of the battens is automatically achieved; and in the welding process, the balancing weight does not need to be turned over, so that the labor intensity of workers for aligning the side edges of the battens one by one and turning over the balancing weight is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ship transformation, in particular to a method for forming a solid ballast counterweight. Background technique [0002] When the cargo carried by the sailing ship arrives at a specific port, the cargo will be unloaded. In order to maintain the balance of the ship when sailing and berthing, generally some materials with high density and high specific gravity are loaded on the bottom of the ship as counterweights. Also known as solid ballast. In the process of undertaking the refitting of the ship, our company encountered a project that needed to add more than 1,000 tons of solid ballast to the inner bottom plate to improve the stability of the hull. In order to facilitate the production of solid ballast, the overall solid ballast is divided into several counterweights for molding and fabrication respectively, and then the counterweights are combined. But every thousand tons of solid ballast needs to make...

AI Technical Summary

Problems solved by technology

But every thousand tons of solid ballast needs to make about 270 counterweights, and each counterweight weighs about 3.7 tons after forming. From this calculation, the counterweight requires a large number of slats, whether it is assembly or welding work The quantity is very large; and when making a single counterweight, it is necessary to align all the slats, and each slat weighs 206 kg, which requires lifting equipment to complete, which brings great difficulties to on-site assembly
