Description

Technical Field

[0001] The present invention relates to the field of rail transportation, and in particular to a component storage and transportation device and a rail vehicle axle box storage and transportation method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Some components, such as axle boxes, lack integrated storage and transportation tooling. Instead, they must be placed sequentially on vehicles for transportation and then moved from the vehicle to the workstation via manual lifting or forklifts (including pallets). During transportation, the axle boxes are not positioned, and only cardboard is used to separate the materials. The process is as follows: loading and unloading (overhead crane lifting, with a total of three people operating the crane and the loading and unloading truck) - forklift transportation (with one forklift operator) - placement of the axle boxes in the work area (overhead crane lifting, with a total of two people operating the crane and the loading and unloading truck) - placement of the axle boxes sequentially.

[0004] The following problems exist: ①The lifting times are high, which occupies the crane resources for a long time and results in low work efficiency; ② There are many operators, the work intensity is high, and the safety is low; ③The axle boxes cannot be stacked, resulting in a large occupied working area; ④ It does not meet the needs of existing digital engineering and production line construction. Materials such as axle boxes need to be automatically transported from the material preparation area to the operation station.

[0005] There are many storage and transportation plates in the existing technology. Some of them simply support the components and cannot limit the components. Moreover, the mass of components such as axle boxes is relatively large. If there is no limit, it is easy to cause problems such as easy bumps and inability to stack during transportation and handling of components. If it is just a simple limit, there is also a problem of insufficient limit for components with more complex structures such as axle boxes; some other storage and transportation plates are aimed at plate-like components or other components, which are not suitable for axle boxes. Moreover, there are many types of axle boxes, and the existing storage and transportation plates are not versatile enough.

[0006] In addition, the space on the storage and transportation plate is limited, and how to reasonably arrange it to transport more axle boxes is also an issue that needs to be considered. Summary of the Invention

[0039] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0040] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly indicated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations; As introduced in the background technology, in the prior art, components such as axle boxes are prone to collision and lack universality during storage and transportation. In order to solve the above technical problems, the present invention proposes a storage and transportation device for components.

[0041] Example 1 In a typical embodiment of the present invention, referring to Figure 1 、 Figure 2 As shown, a storage and transportation device for components can realize the storage and transportation of components such as axle boxes, including a support 34, and the support 34 is provided with a retractable column 6. The storage and transportation device can be stacked when supporting the components, and can also be stacked after the column 6 is retracted. At least one support unit is provided on the surface of the support 34, and the support unit includes a first limiting support member and a second limiting support member. The first limiting support member and the second limiting support member are set at a distance. The first limiting support member supports and limits one side of the component, and the second limiting support member supports and limits the other side of the component. The first limiting support member and the second limiting support member are both movable relative to the support 34, and the height of the second limiting support member is adjustable.

[0042] The storage and transportation device provided in this embodiment has a first limiting support member and a second limiting support member that limit and support one side and the other side of the component respectively, thereby ensuring stable support for the component and fully avoiding interference problems of the component during storage and transportation; the entire support 34 can be stacked, and through the setting of the retractable columns, the support 34 can also support the component after stacking, which is convenient for storage and transportation and effectively increases the transportable volume of the component in a single transportation.

[0043] Regarding the issue of how to achieve stacking, the support 34 is usually rectangular, and the columns 6 are arranged at the four corners of the support. The support 34 includes two layers, one side is the base plate 1, and the other side is the panel 5. The base plate 1 and the panel 5 are set at a distance. The base plate 1 is hollowed out to reduce the mass of the base plate. The base plate 1 and the panel 5 are connected by a connecting column 31, and a fork hole is formed between the two to cooperate with the forklift arm, so that the four sides of the support can cooperate with the forklift arm, and the panel 5 is provided with a support unit.

[0044] refer to Figure 4As shown, the bottom plate 1 is formed by connecting multiple transverse plates and longitudinal plates, which reduces the weight of the entire storage and transportation device while ensuring strength, and can be used for conveyor line rollers for circulation, storage, etc.; the bottom plate 1 is provided with multiple external equipment positioning interfaces 16, and the external equipment positioning interfaces 16 can be circular holes. The external equipment positioning interfaces can cooperate with AGV (autonomous guided vehicle) / RGV (shuttle vehicle), and the AGV / RGV telescopic rod mechanism can be extended into the external equipment positioning interface 16. The power of the AGV / RGV drives the storage and transportation device (with or without materials) to be pulled into the AGV / RGV or pushed out of the AGV / RGV, which is simple and practical.

[0045] Specifically, the panel 5 fixes the protective frame 7 at the four corners respectively, and a recess 17 is provided on the other side of the support away from the protective frame 7. The column 6 is located in the protective frame 7 when upright. The height of the column 6 when upright is greater than the height of the component. When the column 6 is lying down, the height is lower than the protective frame 7. The top of the column 6 and the top of the protective frame 7 can both be inserted into the recess 17 of the support in the adjacent storage and transportation device.

[0046] Among them, a protruding cover 24 is provided on the top of the column 6, the size of the protruding cover 24 is increased, and a bulge is provided on the top of the protruding cover 24. The shape of the recess 17 is the same as the shape of the top of the protruding cover 24, and the size of the recess 17 is slightly larger than the size of the protruding cover, so that the top of the column 6 can be inserted into the recess 17 to realize multi-layer stacking when the support supports the component. In some examples, the protruding cover 24 can be engaged and connected with the recess to further ensure the stability of the support when stacked.

[0047] In this embodiment, the protective frame 7 is a frame-type structure with an opening. The openings of the two protective frames 7 on one side of the support are arranged opposite to each other. The height of the support is less than the height of the column. The size of the protective frame 7 is the same as the size of the column protrusion cover 24, so that the top of the protective frame 7 can be inserted into the support recess 17, realizing multi-layer stacking of the support when there is no material, reducing the storage area. In some examples, the protective frame 7 can be connected by snapping with the column protrusion cover.

[0048] Among them, the bottom of the column 6 is hingedly connected to the bottom of the protective frame 7, and can be specifically connected by a pin 27, so that the column 6 can rotate relative to the protective frame 7 to achieve flat and upright placement of the column 6. The protective frame 7 is provided with a first card slot from the side to the bottom, and the first card slot 33 is L-shaped. The column with a pin 27 is installed on the protective frame 7, and the pin 27 is placed in the first card slot 33. An elastic pin is provided in the middle section of the column, and a second card slot 32 is provided at the top of the protective frame 7. The elastic pin can be inserted into the second card slot 32 of the protective frame 7. Pressing the elastic pin can make the column 6 lie down relative to the protective frame 7; It is easy to understand that after lying down, the column 6 can be placed flat or obliquely on the support 34, as long as the column is set lower than the protective frame 7. The column 6 lies down along the length direction of the support 34. After lying down, the column 6 is placed on the outside of the first limit support member to ensure the rationality of the space setting.
