Description

Technical Field

[0001] The utility model relates to the technical field of cargo ship construction, in particular to a cargo ship trough-type segmented dangerous node measuring device. Background Art

[0002] The pier and corrugated bulkhead of a bulk carrier are two important parts of the hull structure. The pier is an important structure at the bottom of a bulk carrier, which is mainly used to support the hull, disperse the gravity exerted on the hull, and bear the load of the hull under various working conditions. The corrugated bulkhead is a special structure inside the cargo hold of a bulk carrier, and its grooves are along the depth direction of the ship, that is, the grooves are vertical.

[0003] At present, when the trough sections of bulk carriers are manufactured, it is difficult to use conventional angle rulers to measure due to the particularity of the structure of the docking position between the bottom pier and the trough bulkhead, which makes it difficult to check the position of dangerous nodes. The so-called dangerous nodes refer to key nodes where stress is relatively concentrated or fatigue requirements are high. Extra attention needs to be paid to process detection to ensure accuracy requirements such as alignment. When using instruments for measurement, only the bow and stern end positions can be measured, and the middle position cannot be measured at all. When shipowners use measuring rulers to inspect sections, dangerous nodes are must-check items, which are very important. The existing measuring rulers are divided into two: one is the bow measuring ruler, and the other is the stern measuring ruler. The measuring rulers have no effective protective structure and are easily damaged and lost. The deviation of dangerous nodes cannot be intuitively checked. They are very inconvenient to use and carry, and have poor practicality. Therefore, it is necessary to provide a dangerous node measuring device for cargo ship trough sections to solve the above problems. Utility Model Content
