Description

Technical Field

[0001] This utility model relates to a heat treatment pallet rack for aluminum sheets. Background Technology

[0002] During heat treatment of aluminum sheets, they are often placed on wooden pallets and fed into the heat treatment equipment together. However, due to the significant difference in thermal conductivity between wood and aluminum, excessive heat transfer occurs at the contact points between the aluminum sheet and the wooden pallet during heat treatment. This results in uneven heating of the aluminum sheet, affecting the quality of the heat treatment. Furthermore, wooden pallets are prone to damage from prolonged exposure to high temperatures, leading to a shorter lifespan. Utility Model Content

[0003] This utility model addresses the problems existing in the prior art by providing a heat treatment pallet rack for aluminum sheets, which is reasonably designed to improve the heat uniformity of aluminum sheets during heat treatment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an aluminum sheet heat treatment pallet rack, comprising a top steel frame and a bottom steel frame distributed vertically, wherein the bottom steel frame comprises multiple bottom support steel pipes evenly distributed horizontally, and the multiple bottom support steel pipes are arranged longitudinally; the top steel frame comprises multiple top support steel pipes evenly distributed longitudinally, the multiple top support steel pipes are arranged horizontally on top of the multiple bottom support steel pipes, and the bottom of each top support steel pipe is fixedly connected to the top of the multiple bottom support steel pipes respectively.

[0005] Furthermore, each top-level support steel pipe is provided with two clearance grooves along its length, the clearance grooves being longitudinally continuous to facilitate the insertion of forklift forks.

[0006] Furthermore, in the top steel frame, two rectangular steel pipes are provided at the bottom of the top support steel pipes located at the frontmost and rearmost sides. The positions of the two rectangular steel pipes correspond to the positions of the two clearance grooves. The inner cavity of the rectangular steel pipes serves as a fork slot to facilitate the insertion of forklift forks.

[0007] Furthermore, the cross-section of the relief groove is rectangular.

[0008] Furthermore, both the bottom supporting steel pipe and the top supporting steel pipe have rectangular cross-sections.

[0009] Furthermore, the top-layer support steel pipe and the bottom-layer support steel pipe are fixed together by argon arc welding.

[0010] Furthermore, both the top-level support steel pipe and the bottom-level support steel pipe consist of three sections.

[0011] Furthermore, both the top-layer support steel pipe and the bottom-layer support steel pipe are made of Q235 steel.

[0012] Compared with the prior art, the present invention has the following advantages: The present invention has a simple and reasonable structural design. It uses a pallet frame made of steel pipe to support the aluminum plate. The thermal conductivity of the steel pipe is similar to that of the aluminum plate, which reduces the heat transfer between the aluminum plate and the pallet frame during the heat treatment process and improves the heat uniformity of the aluminum plate.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1-3 As shown, this utility model discloses a heat treatment pallet rack for aluminum sheets, entirely constructed of steel pipes. Specifically, it includes an upper steel frame 1 and a lower steel frame 2. The lower steel frame 2 comprises three horizontally spaced lower support steel pipes 3, arranged longitudinally. The upper steel frame 1 comprises three longitudinally spaced upper support steel pipes 4, horizontally positioned on top of the three lower support steel pipes 3. The bottom of each upper support steel pipe 4 is welded to the top of each of the three lower support steel pipes 3. In use, the aluminum sheet is placed directly on the three upper support steel pipes of the upper steel frame, and the aluminum sheet and the entire pallet rack are then fed into the heat treatment equipment for heat treatment. The use of a steel pipe pallet rack to support the aluminum sheet, with a thermal conductivity similar to that of the aluminum sheet, reduces heat transfer between the aluminum sheet and the pallet rack during heat treatment, improving the uniformity of heating of the aluminum sheet. Furthermore, the entire pallet rack is constructed of steel pipes, resulting in better structural strength and extended service life.

[0019] In this embodiment, each top-level support steel pipe 4 is provided with two clearance grooves 5 along its length. The clearance grooves are formed by recessing downwards from the top of the top-level support steel pipe. The clearance grooves 5 are longitudinally continuous to facilitate the insertion of forklift forks. The clearance grooves on the three top-level support steel pipes are correspondingly positioned. When handling aluminum sheets, the forklift forks extend into the clearance grooves. That is, the clearance grooves are used to remove aluminum sheets from the pallet rack or transfer aluminum sheets onto the pallet rack.

[0020] In this embodiment, in the top layer steel frame 1, two rectangular steel pipes 6 are provided at the bottom of the top layer support steel pipes 4 located at the frontmost and rearmost sides. The positions of the two rectangular steel pipes 6 on each top layer support steel pipe correspond to the positions of the two clearance grooves 5. The inner cavity of the rectangular steel pipe 6 serves as a fork slot to facilitate the insertion of forklift forks. In use, the forklift forks extend into the fork slots, at which time the entire pallet frame and aluminum plates can be transported, facilitating their delivery to or removal from the heat treatment equipment.

[0021] In this embodiment, the cross-section of the clearance groove 5 is rectangular.

[0022] In this embodiment, the cross-sections of the bottom supporting steel pipe 3 and the top supporting steel pipe 4 are both rectangular.

[0023] In this embodiment, the top support steel pipe 4 and the bottom support steel pipe 3 are fixed together by argon arc welding, and the rectangular steel pipe and the top support steel pipe are also fixed together by argon arc welding.

[0024] In this embodiment, the top-layer supporting steel pipe 4, the bottom-layer supporting steel pipe 3, and the rectangular steel pipe 6 are all made of Q235 steel, which has good structural strength.

[0025] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0026] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0027] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
