Description

Large aspect ratio solid wood structure pallet

technical field

The invention relates to a pallet for cargo transportation and logistics, in particular to a non-standard solid wood structure pallet with a large aspect ratio.

Background technique

Pallets are the most basic handling tools in the modern logistics industry, and play an extremely important role in the field of commodity circulation. At present, non-standard pallets are commonly used in many industries for collective packaging. For non-standard pallets with an aspect ratio between 1.5 and 2, due to the great difference in bending resistance in the length and width directions, during normal use, Non-standard pallets will have the problem of insufficient performance in one direction. A certain direction of the pallet is more easily damaged, and there are safety hazards in logistics and transportation, resulting in losses of transported products. At the same time, the service life of the pallet is also short.

Contents of the invention

In view of the above problems, the applicant has made research and improvement, and provides a solid wood structure pallet with a large aspect ratio, which balances the bending resistance in the length and width directions on the basis of minimizing the cost, prolongs the service life, and eliminates the need for logistics and transportation. Existing safety hazards to avoid product losses.

In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions:

A solid wood structural pallet with a large aspect ratio, including multiple horizontal top planks and at least 3 vertical support units, the longitudinal support units are arranged in parallel at equal distances, and the horizontal top planks parallel to each other are arranged on the top surface of the longitudinal support units, and the horizontal The laying direction of the top decking and the laying direction of the longitudinal support unit are perpendicular to each other; the longitudinal support unit includes the bottom decking, and the bottom decking is provided with 3 pads, and the 3 pads are arranged at the two ends and the middle of the bottom decking , the reinforcing plate is arranged on the cushion block; the transverse top plank is connected to the top surface of the reinforcing plate.

further:

Reinforcing pads are provided between the three pads of the longitudinal support unit.

There are 7 horizontal top planks, 3 longitudinal support units, 2 reinforcement blocks are respectively arranged at the front and rear of the longitudinal support unit, and 5 transverse top planks are arranged on the cushion blocks and Just above the reinforcement block.

The spacing ratio of the reinforcing pads to the end pads of the longitudinal support unit and the middle pads of the longitudinal support unit is 1:5.

The ratio of the distance between the horizontal top plank not arranged above the spacer or the reinforced spacer, the distance between the middle transverse top plank and the transverse top plank on the other side is 3:5.

Technical effect of the present invention is:

A solid wood structure pallet with a large aspect ratio disclosed by the present invention balances the length and width on the basis of cost minimization by rationally configuring the number and position of cushion blocks and reinforcing cushion blocks, and at the same time rationally adjusting the laying position of the horizontal top surface plank. The anti-bending performance of the pallet improves the overall anti-bending performance of the pallet, prolongs the service life, eliminates potential safety hazards in logistics and transportation, and avoids product losses.

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1, 2, and 3, the present invention includes 7 horizontal top planks 1 and 3 longitudinal support units 2, and the 3 longitudinal support units 1 are arranged in parallel at equal distances, and the horizontal top planks 1 parallel to each other are nailed together. The top surface of the longitudinal support unit 2, the laying direction of the horizontal top surface plank 1 and the laying direction of the longitudinal support unit 2 are perpendicular to each other, the transverse top surface plank 1 is flat, and the laying direction of the transverse top surface plank 1 is the width direction of the pallet. The laying direction of the vertical support unit 2 is the length direction of the pallet, and the quantity of the horizontal top surface plank 1 and the vertical support unit 2 is configured according to the overall length and width of the pallet. The longitudinal support unit 2 includes a bottom plank 3, on which there are three spacers 4, and the three spacers 4 are arranged at both ends and in the middle of the bottom plank 3, and between the three spacers 4 of the longitudinal support unit 2 Reinforcement pads 6, two reinforcement pads 6 are arranged on the front and rear of the longitudinal support unit 2 respectively, the reinforcement board 5 is arranged on the pad 4, and the horizontal top surface plank 1 is connected to the top surface of the reinforcement board 5, wherein , 5 horizontal top planks 1 are arranged directly above the cushion block 4 and the reinforced cushion block 6 . In this embodiment, the distance between the reinforcing pad 6 and the end pad 4 of the longitudinal support unit 2 is B, the distance between the reinforcing pad 6 and the middle pad of the longitudinal support unit is C, and the ratio of B to C is 1: 5. The distance between the horizontal top plank 1 not located above the spacer 4 or the reinforced spacer 6 and the middle transverse top plank is D, and the distance between the transverse top plank 1 and the transverse top plank 1 on the other side is E , the ratio of D and E is 3:5.

When assembling solid wood pallets, prepare 7 horizontal top planks 1, 3 bottom planks 3, 3 reinforcement plates 5, 9 spacers 4, and 6 reinforcement blocks 6. The pads 6 are nailed together according to the structure shown in Figure 1, and then the reinforcement board 5 is flatly laid on the pad 4 and the reinforcement pad 6 and nailed together to form the longitudinal support unit 2; finally, the horizontal top surface is paved 1 Lay on it in a direction perpendicular to the longitudinal support unit 2, and nail it together, among which, 5 horizontal top planks 1 are nailed on the top of the cushion block 4 and the reinforcement block 6, and the remaining 2 horizontal top surface planks 1 are nailed together On both sides of the plank 1 on the middle transverse top surface and nailed to the reinforcing plate 5 of the longitudinal support unit 2 . Each of the above nailing positions is nailed in a triangular shape with three nails.

The present invention effectively enhances the bending resistance of the pallet by arranging the reinforcing pad 6 and rationally adjusting the arrangement position and thickness of the horizontal top decking 1, which can not only ensure the efficient use of the plate consumption, but also enhance the overall bending resistance of the pallet , expanding the scope of use of non-standard pallets.
