Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a fast-connected identification plate fixing device. Background Art

[0002] Crane signage is an indispensable part of cranes, and there are various ways to fix it. At present, the fixing carrier of crane signage is usually the crane railing. The crane railing is welded by three horizontal bars and multiple vertical bars, and the signage is mainly fixed on the three horizontal bars. The traditional installation of signage on the crane railing is to bundle and install it by wire rope. However, the bundling installation method is not only time-consuming and labor-intensive to install, but also the signage is very easy to loosen and fall off during the long-term operation of the crane. Therefore, in order to ensure the firm and stable installation of the signage, the existing signage is often prepared with connecting parts compatible with the crane railing for installation. However, since the diameters of the welded round tubes and the spacing between the railing cross bars of different crane railings are different, the connecting parts of the signage will change with the changes in the diameter of the crane railing round tube and the spacing between the cross bars, and cannot be unified. Therefore, there is an urgent need for a signage fixing device that can adapt to the changes in the diameters of different crane railings and can also be adjusted according to the changes in the spacing between the crane railing cross bars.
