Reinforcnig device for ship hatch cover

Abstract

The present invention relates to a reinforcement device for hatch cover, fixedly connected on the top portion of original top plate. It includes new surface plate, supporting and external web plate. The described external web plate is connected with new surface plate, and they are formed into one body with T-shaped structure or the described external web plate and original top plate are formed into one or several box body structures together. After the above-mentioned reinforcement device is adopted, the main structure of original hatch cover can be remained, has no need of makking new component, and the technical transformation with large range can be implemented.

Description

technical field [0001] The invention relates to a reinforcing device for reinforcing existing ship hatch covers. Background technique [0002] The hatch covers of existing ships have the following problems: [0003] 1. For parts such as hatch covers of ships, due to daily use and seawater corrosion, the thickness of the steel plates gradually becomes thinner, which reduces the strength and affects the safety of the ship. [0004] 2. to figure 1 Take the components shown as an example. After the upper part of the top panel is subjected to loads such as huge waves, the top plate will be subjected to a compressive stress. When the compressive stress exceeds a certain limit value, the top plate will buckle and the entire device will be completely damaged. , causing marine accidents, and even threatening the safety of ships and personnel. [0005] 3. Because the above-mentioned ship hatch covers are assembled and manufactured by welding, it is difficult to disassemble and repl...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the daily use and corrosion of seawater, the thickness of the steel plate gradually becomes thinner for the hatch cover and other parts of the ship, which reduces the strength and affects the safety of the ship.

[0004] 2. to figure 1 Take the components shown as an example. After the upper part of the top panel is subjected to loads such as huge waves, the top plate will be subjected to a compressive stress. When the compressive stress exceeds a certain limit value, the top plate will buckle and the entire device will be completely damaged. , causing maritime accidents, as well as threatening the safety of ships and personnel

[0005] 3. Because the above-mentioned ship hatch covers are combined and manufactured by welding, it is difficult to disassemble and replace them. Once a major problem occurs, the only way to solve it is to replace the entire hatch cover device.

In addition, because the structure of the hatch cover is generally flat, the longitudinal strength of the device is relatively weak, the section coefficient of the beam is small, the deformation after loading is large, and the stress generated on the top and bottom plates is also high, which is difficult to meet the requirements of the classification society. specification requirements
