Steel plate conveying device for ship construction
Technical Field
The utility model relates to the technical field of ship construction, in particular to a steel plate conveying device for ship construction.
Background
In the steel ship construction process, huge and complex ship structures are formed by cutting a plurality of whole steel plates into a certain specification shape, assembling and welding. When the steel plate is lifted by the crane, the steel plate is easy to generate larger bending to form larger arch shape, so that the steel plate is deformed, and the steel plate needs to be manually matched when being lifted off, so that the phenomenon that the crane cannot be unhooked rapidly due to continuous bending of the steel plate is avoided, particularly, the steel plate with smaller thickness is easy to generate deformation, even fracture, the labor intensity of workers is high, and the steel plate is inconvenient to use;
In view of the above, chinese issued patent publication No. CN202020611649.8 discloses a "movable steel plate transporting device", which is configured to prevent the steel plate from being deformed by placing the steel plate on the base, hooking the lifting lug by the crane with the hook, and hooking the lifting rope by the crane with the lifting lug for lifting by the hook connected with the lifting rope;
However, after the steel plate is placed on the base, the steel plate is limited and prevented from sliding mainly through the fixing pipe, and in the actual transportation process, the size of the steel plate is changeable, and some large-size steel plates cannot be limited, so that the base cannot support the steel plate.
