Description

Technical Field

[0001] The utility model relates to the field of transportation and storage of plastic pallets, in particular to a placement rack for stacking plastic pallets. Background Art

[0002] Plastic pallets are also plastic support plates and plastic table tops; they are the main equipment for warehouse storage and cargo transfer. In the plastic pallet production factory, there are a large number of plastic pallets and they need to be transported to the customer's location.

[0003] When storing plastic pallets, they are stacked together without fixed racks or other devices to restrain them. Usually, ropes are used to tie the stacked plastic pallets together. In this way, because the ropes are soft, the plastic pallets are easy to slip, or the stacked plastic pallets are misaligned with each other, resulting in a shift in the center of gravity, which in turn causes the stacked plastic pallets to tip over. When transporting plastic pallets, in order to ensure transportation efficiency, it is necessary to carry as many plastic pallets as possible under the premise of load and height limits, so plastic pallets are also stacked in the cargo hold of the truck, and the stacking height is usually higher than the cargo hold; the part above the cargo hold is also restrained by ropes, which may also cause the plastic pallets to slip or the stack to tip over, and it is even more likely to happen during the bumpy journey of transportation. Whether it is the slipping of plastic pallets or the tipping of stacks, it may pose a danger to factory personnel, transportation personnel, etc.

[0004] Therefore, in order to ensure the stability of the stacking of plastic pallets and to ensure the safe stacking of plastic pallets during transportation and storage, it is necessary to provide a placement rack for restraining the plastic pallets. Utility Model Content

The locking screw is threadedly connected to the threaded hole and abuts against the outer wall of the lower section of the tube.

[0013] Furthermore, all constraint rods are fixedly connected to the base plate; or all constraint rods are hinged to the base plate; or some constraint rods are hinged to the base plate, called hinged rods, and another part of constraint rods are fixedly connected to the base plate, called fixed rods, and the positions of all hinged rods and all fixed rods are symmetrical about the same geometric diagonal position on the base plate.

[0022] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0023] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0024] Example 1

[0025] like Figure 1 As shown, a placement rack for stacking plastic pallets includes a base plate 1, the geometric size and shape of the plastic pallet match the geometric size and shape of the base plate 1, for example, the plastic pallet is a polygon, and the base plate 1 is also a polygon with the same number of sides; at least one hard restraint rod 2 is connected to each side of the base plate 1, the restraint rod 2 is vertically assembled, and the spacing between adjacent restraint rods 2 is less than the side length of the base plate 1, all the restraint rods 2 restrain the plastic pallets stacked on the base plate 1 by surrounding them, and the spacing between adjacent restraint rods 2 is less than the side length of the base plate 1, the geometric size and shape of the plastic pallet match the geometric size and shape of the base plate 1, thereby effectively preventing the plastic pallet from slipping and stacking and tipping over, and improving the stability and safety of the plastic pallet stacking.

[0026] In this embodiment, all the restraining rods 2 are connected to and locked to the same clamping member 3 for clamping the plastic pallets. The clamping member 3 clamps the plastic pallets so that the stacked plastic pallets are constrained in the vertical direction. That is, the clamping member 3 cooperates with all the restraining rods 2 to further constrain all the plastic pallets in the stack into a whole, effectively preventing the center of gravity from shifting and the plastic pallets from jumping up and down during transportation, thereby improving the stability and safety of the plastic pallet stacking.

[0027] Example 2

[0028] Based on Example 1, a specific implementation method that can be implemented is further proposed.

[0029] A feasible implementation method, for the pressing member 3, this embodiment proposes the following several feasible implementation methods.

[0030] In the first embodiment, the clamping member 3 is a star-shaped frame having clamping strips having the same number as the total number of the restraining rods 2. The end of each clamping strip is provided with a through hole 31 for the restraining rod 2 to pass through. After the stacking of the plastic pallets is completed, the star-shaped frame is put on all the restraining rods 2, that is, the top of the restraining rod 2 passes through the through hole 31, and the star-shaped frame is pressed against the top of the topmost plastic pallet, thereby achieving the stacking of the plastic pallets.

[0031] In the second embodiment, the clamping member 3 is a plate member having through holes 31 which are the same in number and matched in position as the total number of the restraining rods 2; after assembly, the restraining rods 2 pass through the through holes 31; the clamping principle is the same as that of the star frame described in the first embodiment, and no further detailed description is given here.

[0032] It should be noted that the clamping member 3 is preferably a star-shaped frame, which can ensure that the plastic pallet is clamped and restricted while having a larger space gap. The star-shaped frame is lighter than the plate, which is convenient for operators to install and disassemble.

[0033] On the basis of the first and second embodiments, a feasible embodiment is further proposed, in which a threaded section 22 is provided on the top of the constraint rod 2, and a clamping nut 4 is connected to the threaded section 22. The assembly position of the clamping piece 3 is located between the clamping nut 4 and the base plate 1, and the aperture of the through hole 31 is smaller than the outer diameter of the clamping nut 4. The clamping nut 4 is threadedly connected to the screw rod, and the base plate 1 and the plastic pallets stacked on the floor are cooperated to lock the clamping piece 3, and then the pre-tightening force of the threaded connection between the clamping nut 4 and the threaded section 22 acts on the clamping piece 3, which is converted into a pressure for pre-tightening the clamping piece 3 on the plastic pallet.

[0034] Example 3

[0035] Based on any one of the implementations in Examples 1-2, a specific implementation method that can be implemented is further proposed.

[0036] In order to adapt to the stacking height of various plastic pallets and save the placement space occupied by the placement rack when not in use, the restraint rod 2 is a multi-section telescopic rod with a multi-section tube body 21. Adjacent tube bodies 21 are slidably connected to each other, and the extension and retraction of the multi-section telescopic rod is achieved by sliding the tube body 21, thereby adjusting the overall length of the restraint rod 2 to further adapt to the stacking height of the plastic pallets.

[0037] Furthermore, there are locking pieces between adjacent tubes 21 in the multi-section telescopic rod for locking the telescopic length, so as to lock the length of the restraining rod 2 so that the length of the restraining rod 2 will not change during transportation, thereby ensuring that the plastic pallet will not jump up and down during transportation.

[0038] Specifically, there are an upper section of the tube and a lower section of the tube in the adjacent tube body 21, and the upper section of the tube is sleeved in the lower section of the tube, that is, the lower section of the tube can extend or retract into the upper section of the tube; the locking member is a locking screw 23, and a threaded hole is opened on the upper section of the tube, and the threaded hole passes through the tube wall. The locking screw 23 is threadedly connected to the threaded hole and abuts against the outer wall of the lower section of the tube. The outer wall of the lower section of the tube is tightened by the locking screw 23 so that the outer wall of the lower section of the tube is tightly attached to the inner wall of the upper section of the tube, and then there is a high friction between the two to achieve locking.

[0039] Example 4

[0040] Based on any one of the implementations in Examples 1-3, a specific implementation method that can be implemented is further proposed.

[0041] Regarding the connection method between the restraining rod 2 and the base plate 1, the following implementation methods are proposed in this embodiment.

[0042] In the first implementation mode, all the restraining rods 2 are fixedly connected to the bottom plate 1 . In this manner, when placing the plastic pallet, it is necessary to place it from the top of the space surrounded by the restraining rods 2 .

[0043] In the second embodiment, all the restraint rods 2 are hinged to the base plate 1, and the restraint rods 2 can rotate around the hinge position. In this way, when placing plastic pallets, the restraint rods 2 rotate to release the space surrounded by all the restraint rods 2, and the plastic pallets can be directly placed on the base plate 1 for stacking; compared with the first embodiment, this method is more convenient for stacking plastic pallets.

[0044] In the third embodiment, some of the constraint rods 2 are hinged to the bottom plate 1, which are called hinged rods, and the other part of the constraint rods 2 are fixedly connected to the bottom plate 1, which are called fixed rods. The positions of all the hinged rods and all the fixed rods are symmetrical about the same geometric diagonal surface on the bottom plate 1. In this way, when placing plastic pallets, the hinged rods can be rotated to release the space surrounded by all the constraint rods 2, and the plastic pallets can be directly placed on the bottom plate 1 for stacking. At the same time, the fixed rods can also be used to position the plastic pallets, that is, when placing the plastic pallets, the side of the plastic pallets rests on the fixed rods to ensure that all plastic pallets are stacked in the correct position. Taking the bottom plate 1 as a rectangle as an example, there are 4 constraint rods 2, of which two adjacent constraint rods 2 are used as hinged rods, and the other two adjacent constraint rods 2 are used as fixed rods. The fixed rods and the hinged rods are symmetrical with respect to the diagonal surface of the rectangle.

[0045] In summary, among the three implementation modes, the third implementation mode is preferred.

[0046] In this embodiment, a rotating shaft 11 is provided at a hinged position of the bottom plate 1 with the restraining rod 2 , and the restraining rod 2 is rotatably connected to the rotating shaft 11 , and the restraining rod 2 rotates in a vertical plane.

[0047] Example 5

[0048] Based on any one of the implementation methods in Examples 1-4, a specific implementation method that can be implemented is further proposed.

[0049] The bottom of the base plate is provided with a universal wheel 5 with a brake, which is convenient for moving the stacked plastic pallets; the universal wheel 5 with a brake is available in the market and will not be described in detail here.

[0050] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
