Testing device for curved external board of ship body

Abstract

The invention discloses a testing device for a curved external board of a ship body. The testing device comprises a plurality of continuously distributed testing units. Each testing unit comprises a reference plane, and a plurality of rib position reference rods which are parallelly and separately distributed according to the rib distance of a to-be-tested curved external board of the ship board. Two ends and the middle point of each rib position reference rod are provided with vertical supporting rods which are perpendicular with the reference plane and can telescope for being adjusted. The testing unit further comprises rib position adjusting strips and longitudinal fixing strips. The rib position adjusting strips are respectively connected with top end of a vertical supporting rod which is vertically arranged on the rib position reference rod. The longitudinal fixing strip is connected with the left end point or the right end point or the middle point of the rib position adjusting strip. The testing device for the curved external board of the ship body is used as a measurement and auxiliary device which can replace a wooden sample box and has advantages of effective recyclability and high convenience in use. Furthermore the testing device has advantages of greatly reducing use of wood, reducing number of work procedures, and saving ship manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to an inspection device for a curved surface outer plate of a ship body. Background technique [0002] In the manufacture of ship and ocean engineering equipment, the curved outer plate and the section of the outer plate with curved surface need to be inspected with a sample box to see whether the curved shape meets the requirements of the hull line. The sample box is made according to the hull plate shape value generated by TRIBON ship design software and computer lofting, and it is used as a tooling for inspection of complex curved hull plate bending forming. Currently, the shipyards still use traditional wooden special sample boxes. A large number of wooden sample boxes are used in the production of hull panels, and the shipyard has specialized workshops and types of work for making wooden sample boxes. Workers use wood to make horizontal and vertical components based on ...

AI Technical Summary

Problems solved by technology

And the bending data of each outer plate is different. The sample box made of wood is too fixed, and it is made according to the ratio of 1:1. Each complex curved steel plate needs to customize a sample box, and each wooden sample box It is often scrapped after only one use, and its production is cumbersome, time-consuming and material-intensive, and inconvenient to store

The surface area of ​​a ship is basically more than 50% of the area of ​​the outer plate, and the production volume is huge, resulting in a sharp increase in the amount of wood and labor
