The steel tray for transporting the aluminum coils has the advantages that through the structural design of the steel tray, light weight can be achieved; due to the structural design of the supporting beam, namely the bending of the cover plate and the bottom edge (namely the design of the lower flange and the upper flange), the structure can be more stable, and supporting is firmer.

Description

Technical Field:

[0002] The utility model relates to a steel pallet, in particular to a steel pallet for transporting aluminum coils, which can be applied to aluminum coils with a diameter of 1400 - 1800 mm. Background Art:

[0004] An aluminum coil is a cylindrical coil formed by winding aluminum plates. In the past, after the aluminum coil was formed by winding, it was placed on a wooden pallet. The wooden pallet includes a cuboid frame board and two retaining bars arranged on the upper surface of the cuboid frame board. Due to the large weight of the aluminum coil, the wooden pallet collapses, deforms or breaks after being used several times, with a short service life. Moreover, after being damaged, the supporting effect on the aluminum coil is poor, and the phenomenon of the aluminum coil slipping is likely to occur, resulting in safety accidents.

[0005] Therefore, the disadvantages of the wooden pallet are as follows: 1) The connection strength between the components of the existing wooden pallet is insufficient, and it is easily damaged by collision during transportation and cannot be repaired or recycled after being damaged; 2) There is no felt or the felt cannot be fixed on the existing wooden pallet, resulting in quality defects; 3) The service life or the frequency of recycling of the wooden pallet is short; 4) The flatness of the manufacturing angle of the two bars on the wooden pallet is insufficient, resulting in insufficient contact surface and easy generation of problems such as bumps or indentations.

[0006] Currently, the Chinese patent "An Aluminum Coil Pallet" with the publication number CN220221583U is retrieved. It includes a pallet main body, and two stabilizing structures are symmetrically installed on the pallet main body. The stabilizing structures can slide on the pallet main body. The stabilizing structure is composed of an installation connecting rod and stabilizing base rods. There are two stabilizing base rods and they are symmetrically installed at the left and right ends of the installation connecting rod. Four limiting baffles are symmetrically installed on the pallet main body, and the limiting baffles can rotate on the pallet main body. Although the stabilizing structure is slidably arranged on the pallet main body, when transporting the aluminum coil main body, the stabilizing structure on the pallet main body can be pulled outwards and unfolded, thereby increasing the stability of the placement of the pallet main body. Furthermore, the pallet main body and the aluminum coil main body thereon are not easily toppled when being transported. When storing the aluminum coil main body, the stabilizing structure can be pushed inwards and contracted, so that the overall occupied space is smaller. However, the structure of this patent is not reasonably designed, with a large weight and poor supporting effect. Summary of the Invention:

[0008] In view of the above existing problems, the purpose of the utility model is to provide a steel pallet for transporting aluminum coils. The steel pallet for transporting aluminum coils is reasonably designed, which is beneficial to improving the service life and supporting stability of the steel pallet, and has a relatively light weight.

A plurality of reinforcing rib plates are arranged at intervals in the body surrounded by the bottom plate, the two side plates and the cover plate in the length direction of the bottom plate. The bottom plate, the two side plates, the cover plate and the reinforcing rib plates are fixedly connected by welding to each other.
