Description

Technical Field

[0001] This invention relates to the field of tooling technology for parts storage and transfer, and particularly to a pallet and a pallet assembly containing the pallet. Background Technology

[0002] In the shipbuilding and steel structure manufacturing industries, pallets are important tooling equipment used for stacking and transferring materials such as finished pipes, scaffold boards, scaffold parts and outfitting components.

[0003] Currently, existing pallets are not suitable for different types of materials. When loading long, narrow materials, the side panels can easily cause interference, and when loading loose items, they lack effective protection, resulting in poor versatility. In addition, existing pallets occupy a large amount of floor space during storage, leading to low site utilization. Furthermore, the wide variety of pallet types and inconsistent specifications make on-site fixed-position management difficult.

[0004] Therefore, there is an urgent need for a pallet that can flexibly change its shape according to the materials being loaded and can improve the utilization rate of the site. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of poor pallet versatility and large storage area in the prior art, and to provide a pallet and pallet assembly containing the pallet.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A pallet includes a base plate, two first side plates arranged opposite each other along a first horizontal direction, two second side plates arranged opposite each other along a second horizontal direction, and a connecting assembly. The connecting assembly includes a first connector and a second connector. The first horizontal direction and the second horizontal direction are perpendicular to each other. The two first side plates are respectively fixedly connected to both sides of the base plate along the first horizontal direction. The two second side plates are respectively detachably connected to the two first side plates through the connecting assembly.

[0008] The first side plate is fixedly connected to the bottom plate to ensure the integrity and stability of the pallet body structure. The second side plate is detachably connected to the first side plate, and the same pallet can flexibly switch forms according to the type of material being loaded. When the pallet is used to place finished pipes or scaffold boards, the two second side plates can be removed to accommodate longer loading materials. When the pallet is used to place bulk materials, the two second side plates can be installed to prevent the bulk materials from falling off in the second horizontal direction.

[0009] Preferably, the bottom of the base plate is provided with a sleeve structure, and the top of the first side plate is provided with a plug-in structure adapted to the sleeve structure.

[0010] By combining the plug-in structure and the sleeve structure, the plug-in structure can be inserted into the sleeve structure of another pallet, thereby enabling the stacking of two adjacent pallets and effectively improving the utilization rate of the space.

[0011] Preferably, the internal cavity of the sleeve structure is a circular cavity, the insertion structure is a cylinder, and the radial dimension of the insertion structure is smaller than the radial dimension of the sleeve structure.

[0012] The combination of the circular cavity and the cylinder allows for easy insertion of the upper and lower pallets without the need for precise angle alignment, enabling insertion at any circumferential position. The radial dimensional difference creates a guide gap, allowing the insertion structure to smoothly enter the sleeve structure, reducing the requirements for operational precision and improving stacking efficiency.

[0013] Preferably, the first connector is a fixed ear plate, the first connector is a pin, the fixed ear plate is correspondingly disposed on the first side plate, the pin is fixedly connected to the second side plate, and the pin passes through the fixed ear plate to realize the detachable connection between the second side plate and the first side plate.

[0014] The mechanical connection method using fixed ear plates and pins is simple and reliable. The insertion and removal operations can be completed without the aid of tools, which makes it easy for workshop workers to quickly switch pallet forms according to the type of materials loaded, thus improving the flexibility and efficiency of production operations.

[0015] Preferably, the tray further includes lifting lugs, which are provided at all four corners of the tray.

[0016] The lifting lugs are located at the corners to ensure that the pallet is subjected to even force during lifting, keeping it level and stable in the air, preventing materials from slipping due to tilting, and ensuring the safety of lifting operations.

[0017] Preferably, the first side plate has a mesh structure;

[0018] And / or, the second side plate has a mesh structure;

[0019] And / or, the base plate, the first side plate, and the second side plate are all welded from structural steel;

[0020] And / or, the first side plate is provided with a reinforcing structure.

[0021] By designing the first and second side panels as a grid structure, the weight of the side panels is significantly reduced while ensuring sufficient enclosure strength. This achieves further lightweight design of the pallet, reducing material costs and energy consumption during logistics and transportation. Furthermore, the bottom plate, first side panel, and second side panel are all welded from structural steel, providing excellent structural strength and resistance to deformation.

[0022] Preferably, the base plate, the first side plate, and the second side plate together form a receiving space for receiving bulk materials, which include one or more of scaffold parts, lamp holders, and cable supports.

[0023] The base plate, together with the first and second side plates in two directions, forms a three- or four-sided enclosed space, which can effectively prevent small outfitting parts such as scaffolding parts, light frames and cable brackets from falling off due to bumps during logistics transfer, ensuring the cleanliness and safety of the transfer process.

[0024] Preferably, the base plate includes a grid-like bottom surface, the size of the grid holes of the grid-like bottom surface being smaller than the minimum size of the bulk material contained in the pallet.

[0025] The grid-like bottom surface significantly reduces the pallet's weight while maintaining load-bearing strength, achieving a lightweight design that lowers material costs and energy consumption during logistics and transportation. The grid holes prevent small-sized bulk materials from leaking out from the bottom.

[0026] Preferably, the base plate further includes a plurality of support members disposed at the bottom of the grid-shaped base surface.

[0027] While reducing weight, the grid-like bottom surface sacrifices some structural rigidity. By adding multiple support components at the bottom, a reinforcing structure is formed below the grid nodes or grid edges on the bottom surface, which effectively compensates for the strength loss caused by the grid design. This allows the pallet to meet the rated load requirements while being lightweight, thus balancing the dual needs of weight reduction and load-bearing capacity.

[0028] The present invention also provides a pallet assembly comprising at least two pallets stacked on top of each other as described above, wherein the bottom of the base plate is provided with a sleeve structure, and the top of the first side plate is provided with a plug-in structure adapted to the sleeve structure, wherein the plug-in structure of the lower pallet is inserted into the sleeve structure of the upper pallet.

[0029] Pallet assemblies, formed by stacking multiple pallets, allow for the simultaneous lifting of two layers of pallets during logistics transfers, reducing the number of lifting operations and improving efficiency. In warehousing, they significantly reduce floor space requirements, greatly enhancing site utilization. The interlocking and sleeve structures, combined with the stacked arrangement, create a self-locking mechanism to prevent horizontal slippage of the upper pallet during transport, ensuring stability and safety in the stacked configuration.

[0030] The positive advantages of this invention are as follows: the first side plate is fixedly connected to the bottom plate, ensuring the integrity and stability of the pallet body structure; and through the detachable connection between the second side plate and the first side plate, the same pallet can flexibly switch forms according to the type of material being loaded. When the pallet is used to place finished pipes or scaffold boards, the two second side plates can be removed to accommodate longer loads. When the pallet is used to place bulk materials, the two second side plates can be installed to prevent the bulk materials from falling off in the second horizontal direction.

[0055] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0056] like Figures 1-6 As shown, this embodiment provides a tray 1, which includes a base plate 10, two first side plates 20 arranged opposite each other along a horizontal first direction A, two second side plates 30 arranged opposite each other along a horizontal second direction B, and a connecting assembly 40. The connecting assembly 40 includes a first connector 41 and a second connector 42. The horizontal first direction A and the horizontal second direction B are perpendicular (see details). Figure 2 The two first side plates 20 are fixedly connected to the two sides of the base plate 10 along the first horizontal direction A, and the two second side plates 30 are detachably connected to the two first side plates 20 through the connecting assembly 40.

[0057] In this embodiment, the first side plate 20 is fixedly connected to the bottom plate 10 to ensure the integrity and stability of the pallet 1 body structure. Furthermore, the second side plate 30 is detachably connected to the first side plate 20, allowing the same pallet 1 to flexibly switch forms according to the type of material being loaded. When the pallet 1 is used to place finished pipes or scaffold boards, the two second side plates 30 can be removed to accommodate longer loading materials. When the pallet 1 is used to place bulk materials, the two second side plates 30 can be installed to prevent the bulk materials from falling off from the horizontal second direction B.

[0058] like Figures 1-6 As shown, the bottom of the base plate 10 is provided with a sleeve structure 11, and the top of the first side plate 20 is provided with a plug-in structure 21 that is adapted to the sleeve structure 11. The top of the plug-in structure 21 is provided with a sealing plate 210.

[0059] In this embodiment, through the cooperation of the plug-in structure 21 and the sleeve structure 11, the plug-in structure 21 can be inserted into the sleeve structure 11 of another pallet 1, thereby realizing the stacking of two adjacent pallets 1 and effectively improving the space utilization rate.

[0060] like Figures 1-6 As shown, the internal cavity of the sleeve structure 11 is a circular cavity, the insertion structure 21 is a cylinder, and the radial dimension of the insertion structure 21 is smaller than the radial dimension of the sleeve structure 11.

[0061] In this embodiment, the combination of the circular cavity and the cylinder allows the upper and lower trays 1 to be inserted at any circumferential position without needing to be aligned when stacking, making operation convenient. The radial dimensional difference forms a guide gap, allowing the insertion structure 21 to be smoothly inserted into the sleeve structure 11, reducing the requirements for operational precision and improving the efficiency of stacking operations.

[0062] like Figures 1-6 As shown, the first connector 41 is a fixed ear plate, and the second connector 42 is a pin. The fixed ear plate is correspondingly disposed on the first side plate 20, and the pin is fixedly connected to the second side plate 30. The pin passes through the fixed ear plate to realize the detachable connection between the second side plate 30 and the first side plate 20.

[0063] In this embodiment, a mechanical connection method using a fixed ear plate and a pin is adopted. The structure is simple and reliable, and the insertion and removal operation can be completed without the aid of tools. This makes it easy for workshop workers to quickly switch the form of pallet 1 according to the type of loaded materials, thereby improving the flexibility and efficiency of production operations.

[0064] like Figures 1-6 As shown, the tray 1 also includes lifting lugs 50, with each of the four corners of the tray 1 having a lifting lug 50. Furthermore, the outer end of the lifting lug 50 has a smooth transition structure. Specifically, in this embodiment, the lifting lug 50 is located at the connection between the base plate 10 and the first side plate 20.

[0065] In this embodiment, the lifting lug 50 is located at the corner so that the pallet 1 is subjected to uniform force during lifting, and remains horizontal and stable in the air, avoiding material slippage due to tilting and ensuring the safety of lifting operations.

[0066] like Figures 1-6 As shown, both the first side plate 20 and the second side plate 30 have a mesh structure. Specifically, in this embodiment, the first side plate 20 and the second side plate 30 are made of steel mesh. The bottom plate 10, the first side plate 20, and the second side plate 30 are all welded from structural steel. The first side plate 20 is provided with a reinforcing structure 22 in the shape of a right-angled isosceles triangle (e.g., Figure 6 As shown in the figure), and a sign 60 is also provided on the tray 1.

[0067] In this embodiment, by setting the first side plate 20 and the second side plate 30 as a grid structure, the weight of the side plates is significantly reduced while ensuring sufficient enclosure strength. This achieves further lightweight design of the pallet 1, reducing material costs and energy consumption during logistics and transportation. In addition, the bottom plate 10, the first side plate 20, and the second side plate 30 are all welded from structural steel, possessing good structural strength and resistance to deformation.

[0068] like Figures 1-6As shown, the base plate 10, the first side plate 20, and the second side plate 30 together form a receiving space, which is used to receive bulk materials, including one or more of scaffold parts, lamp holders, and cable supports.

[0069] In this embodiment, the base plate 10, together with the first side plate 20 and the second side plate 30 in two directions, forms a three- or four-sided enclosed space, which can effectively prevent small-sized outfitting parts such as scaffolding parts, lamp holders and cable brackets from falling off due to bumps during logistics transfer, thus ensuring the cleanliness and safety of the transfer process.

[0070] like Figures 1-6 As shown, the base plate 10 includes a grid-like bottom surface, and the size of the grid holes 12 on the grid-like bottom surface is smaller than the minimum size of the bulk material contained in the pallet 1.

[0071] In this embodiment, the grid-like bottom surface significantly reduces the weight of the pallet 1 while ensuring load-bearing strength, achieving a lightweight design and reducing material costs and energy consumption during logistics and transportation. The grid holes 12 prevent small-sized bulk materials from leaking out from the bottom.

[0072] like Figures 1-6 As shown, the base plate 10 also includes a plurality of support members 13, which are disposed at the bottom of the grid-like bottom surface.

[0073] In this embodiment, the grid-shaped bottom surface sacrifices some structural rigidity while reducing weight. By adding multiple support members 13 at the bottom, reinforcement is formed below the grid nodes or grid edges of the bottom surface, which effectively makes up for the strength loss caused by the grid design. This allows the pallet 1 to meet the rated load requirements while being lightweight, thus taking into account both the needs of weight reduction and load-bearing capacity.

[0074] like Figures 1-6 As shown, the present invention also provides a pallet assembly, which includes at least two pallets 1 stacked on top of each other as described above. The bottom of the base plate 10 is provided with a sleeve structure 11, and the top of the first side plate 20 is provided with a plug-in structure 21 adapted to the sleeve structure 11. The plug-in structure 21 of the lower pallet 1 is inserted into the sleeve structure 11 of the upper pallet 1.

[0075] In this embodiment, the pallet assembly formed by stacking multiple pallets 1 can lift two layers of pallets 1 at once during logistics transfer, reducing the number of lifting operations and improving logistics transfer efficiency. In warehousing mode, it can significantly reduce the floor space occupied, greatly improving site utilization. After stacking, the interlocking structure 21 and the sleeve structure 11 cooperate to form a self-locking limit, preventing the upper pallet 1 from sliding horizontally during transportation, ensuring the stability and safety of the stacked state.

[0076] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
