[0046] The utility model will be further described in detail in combination with the drawings and examples, and it should be pointed out that the following examples are intended to facilitate the understanding of the utility model and do not have any limiting effect on the utility model.

[0047] Example 1, a molded pallet

[0048] As shown in the drawings, Figure 1 The utility model provides a molded pallet, which comprises a pallet base 1, a foot column 2 and a support plate 3.

[0049] As shown in the drawings, Figures 2-3 and Figure 5As shown, the tray base 1 is square, and the upper surface thereof is provided with a first anti-skid pad 4 and a second anti-skid pad 5. The foot block 2 includes a non-molded foot block 6, a first molded foot block 7, a second molded foot block 8, and a third molded foot block 9, which are arranged below the tray base 1. The first anti-skid pad 4 and the second anti-skid pad 5 are rectangular, the size of the first anti-skid pad 4 is smaller than that of the second anti-skid pad 5, the first anti-skid pad 4 is arranged on the four corners of the upper surface of the tray base 1, and the second anti-skid pad 5 is arranged at the middle of the diagonal angle of the upper surface of the tray base 1. The tray base 1 can fix four barrel-shaped cargos, the lower chassis edge 10 of each barrel-shaped cargo is in contact with the anti-skid pad, and one barrel-shaped cargo needs one first anti-skid pad 4 and two second anti-skid pads 5. The anti-skid pad effectively prevents the cargo from sliding or swinging during transportation by increasing the friction, thereby avoiding damage to the cargo or causing injury. The anti-skid pad is often easily misaligned when transporting empty barrels, and the material of the anti-skid pad includes but is not limited to rubber, PVC, and silicone. The non-molded foot block 6 is arranged on the four corners below the tray base 1, the non-molded foot block 6 is a shavings foot block, and the non-molded foot block 6 is not integrated with the tray base 1, which is fixed below the tray base 1 by means of nails, strong glue, etc., and the number of non-molded foot blocks 6 is four. The first molded foot block 7 is arranged at the middle of the two parallel sides below the tray base 1, and the number thereof is two. The second molded foot block 8 is arranged at the middle of the remaining two parallel sides below the tray base 1, and the number thereof is two. The third molded foot block 9 is arranged at the center position of the diagonal line below the tray base 1, and the number thereof is one. The above three kinds of molded foot blocks are integrated with the tray base 1. The total number of foot blocks is nine, which are arranged in three columns below the tray base 1, and each column has three foot blocks. The first column and the third column are the same, and are respectively non-molded foot block 6-first molded foot block 7-non-molded foot block 6. The second column of foot blocks is respectively second molded foot block 8-third molded foot block 9-second molded foot block 8. The spacing of foot blocks in each column is equal, and the spacing of foot blocks in the same column is also equal, which facilitates the insertion of a forklift to take and place the cargo.

[0050] As Figures 4-6As shown, the non-molded foot block 6, the first molded foot block 7, and the second molded foot block 8, in addition to their supporting function when placed on a flat surface, can also fix and support the goods located below the foot blocks when stacked barrel-shaped goods. When molded pallets and goods are stacked in multiple layers, a structure is formed: bottom molded pallet - bottom barrel-shaped goods - top molded pallet - top barrel-shaped goods. In this case, the lower bottom edge 10 of the lower barrel-shaped goods is fixed by the pallet base 1 of the bottom molded pallet, and the upper bottom edge 11 of the lower barrel-shaped goods is jointly fixed by the non-molded foot block 6, the first molded foot block 7, and the second molded foot block 8 of the top molded pallet. That is to say, except for the topmost goods, the remaining stacked goods have double fixation. During transportation, the goods are more stable with double fixation, less prone to slipping, and increase the stability and safety of the transportation process; during loading and unloading, multi-layer stacking improves the efficiency of goods transfer. It should be noted that molded pallets have a certain load-bearing limit, so molded pallets and goods cannot be stacked indefinitely.

[0051] like Figures 7-8 As shown, the pallet base 1 is also provided with a first reinforcing rib 12, a second reinforcing rib 13, a third reinforcing rib 14, and a fourth reinforcing rib 15. There are four first reinforcing ribs 12, radially distributed along the diagonals of the pallet base 1; there are eight second reinforcing ribs 13, parallel to the four sides of the pallet base 1; there are eight third reinforcing ribs 14, arranged in an arc shape; and there are eight fourth reinforcing ribs 15, perpendicular to the second reinforcing ribs 13. The second reinforcing ribs 13, third reinforcing ribs 14, and fourth reinforcing ribs 15 are distributed along the four sides of the square pallet base 1. A third mold pressing foot 7 located at the center of the pallet base 1 is connected to the four first reinforcing ribs 12; each first mold pressing foot 7 is connected to two second reinforcing ribs 13 and two third reinforcing ribs 14; each second mold pressing foot 8 is connected to two second reinforcing ribs 13 and two third reinforcing ribs 14; and each fourth reinforcing rib 15 is connected to one second reinforcing rib 13 and one third reinforcing rib 14. One first reinforcing rib 12, two second reinforcing ribs 13, two third reinforcing ribs 14, and two fourth reinforcing ribs 15 form a reinforcing rib module, and there are a total of four reinforcing rib modules on the pallet base 1. By distributing the above four different types of reinforcing ribs alternately on the pallet base, the load-bearing capacity and service life of the molded pallet are improved.

[0052] like Figure 9 As shown, the support plate 3 is installed on the foot block and is detachable. The support plate 3 can be installed on three rows of foot blocks, with a total of three plates. By installing the support plate 3, the contact area between the molded pallet foot block and the flat surface can be increased, reducing pressure. Especially when the weight of the goods is close to the load-bearing limit, it can protect the molded pallet and extend its service life.

[0053] Example 2: The Influence of Different Types of Foot Blocks on the Ultimate Load of Molded Pallets

[0054] The difference between this embodiment and embodiment 1 is that the foot blocks at positions 1-8 are changed to different combinations and numbers of non-molded foot blocks, first molded foot blocks, and second molded foot blocks, as shown in Table 1. Figure 10

[0055] Table 1, different combinations of foot blocks

[0056]

[0057]

[0058] The foot block combination of the molded tray provided in combination 1 is the same as that of embodiment 1, the difference between combination 2 and combination 1 is that the positions of the molded foot blocks are exchanged with those of the non-molded foot blocks, the foot blocks of combination 3 are all molded foot blocks, and the foot blocks of combination 4 are all non-molded foot blocks.

[0059] The molded trays made of the above four different foot block combinations are subjected to limit load detection, and the detection method is referred to the limit load U in the “Performance Requirements and Test Selection for Intermodal General Pallets” (standard number: GB / T 4995-2014). The detection results are shown in Table 2. It should be noted that the size of the first molded foot block is slightly larger than that of the second molded foot block, but it can be ignored when detecting the limit load.

[0060] Table 2, limit load of molded tray with different combinations of foot blocks

[0061] footing assembly assembly 1 assembly 2 assembly 3 assembly 4 ultimate load (t) 1.85 1.63 1.54 1.46

[0062] According to the data analysis in Table 2, the limit load of the molded tray containing the foot blocks of combination 1 and combination 2 is higher than that of the molded tray containing the foot blocks of combination 3 and combination 4, indicating that the combination of non-molded foot blocks and molded foot blocks can improve the limit load of the molded tray. The foot blocks of combination 3 are all molded foot blocks, which have lower compressive strength than non-molded foot blocks, so the limit load is reduced. The foot blocks of combination 4 are all non-molded foot blocks, but the non-molded foot blocks are not integral with the tray base, so they are not connected with the reinforcing ribs, resulting in a reduction in the limit load. Comparing the molded trays containing the foot blocks of combination 1 and combination 2, it is shown that the limit load of the molded tray containing the foot blocks of combination 1 is higher, indicating that the effect of improving the limit load is better when the non-molded foot blocks are arranged at the four corners of the tray base than when they are arranged in the middle of the four edges of the tray base.

[0063] Preferably, the foot block combination mode of combination 1 is selected.

[0064] ​Although the utility model discloses as above, the utility model is not limited to this. Any person skilled in the art, without departing from the spirit and scope of the utility model, can make various changes and modifications, therefore the protection scope of the utility model should be limited to the range defined by the claims.
