Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a steel plate transportation device for shipbuilding. Background Art

[0002] During the construction of steel ships, the huge and complex hull structure is made up of several whole steel plates that are cut into certain specifications and shapes and assembled and welded. When the steel plates are shipped out for cold processing, they are usually transported to the cold processing area for rolling and forging by crane hooks or forklift forks. When the steel plates are transported by crane, it is easy for the steel plates to bend greatly, forming a large arch, causing the steel plates to deform. When unloading the steel plates, manual cooperation is required to avoid the continuous bending of the steel plates, which causes the crane to be unable to unhook quickly. Especially for steel plates with thinner thickness, they are easy to deform or even break, which is labor-intensive for workers and inconvenient to use.

[0003] In this regard, China's authorized patent publication number CN202020611649.8 discloses "a flexible steel plate transportation device", which effectively avoids the problem of steel plate deformation by placing the steel plate on a base, then using a crane to hook the lifting lug for lifting, using a lifting rope to connect the lifting lug, and then hooking the lifting rope with the crane's hook for lifting;

[0004] However, after the steel plate is placed on the base, the patent mainly limits the steel plate by fixing the tube to prevent it from sliding. However, during the actual transportation process, the size of the steel plate varies, and some large-sized steel plates cannot be limited, which results in the base being unable to support the steel plate.
