Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, and particularly relates to a stacked wheel set packaging and transportation rack with axle boxes. Background Art

[0002] The wheel set uses the Y25 series bogie as the most mainstream 25t axle load freight bogie in Europe and even the world at present. It is a railway freight bogie with an integral welded frame and a primary suspension, and has the characteristics of light weight and good flexibility. It has been recognized by the International Union of Railways (UIC) as the standard freight bogie for European railways. The BA319 wheel set axle box assembly is mainly used for Y25 or similar structure bogies and is one of the extremely important components.

[0003] The packaging cost of the wheel set affects the selling price of the wheel set, and thus affects the market competitiveness. During handling and transportation, it is required that the stacked wheel sets are firmly packaged without loosening, side slipping, bruising, etc. Each stack of packages stacks 6 wheel sets, and the wheel sets are placed staggeredly with each other. At the same time, the collision of the axle boxes needs to be considered. For the conventional 6-wheel set packaging rack, the distance between the wheel sets is only staggered by about the width of one wheel rim, which is far from enough for the wheel set with axle boxes.

[0004] It is expected to provide a stacked wheel set packaging and transportation rack with axle boxes that can solve the above technical problems. Summary of the Utility Model
