Abstract

The invention provides a pallet, which comprises two parallel square bars and at least one middle square bar arranged between the two parallel square bars and parallel to the two parallel square bars; uniformly distributing plates between the two parallel square bars to form an upper supporting surface and a lower supporting surface of the pallet; and four corners of the upper supporting surface and the lower supporting surface are respectively fastened by adopting reinforcing steel bars. According to the invention, on the basis of a common wooden pallet, reinforcing steel bars are adopted to replace traditional wooden screws or iron nails, and the upper and lower transverse plates which are the most adjacent sides of the pallet are structurally improved, so that the problem of pallet looseness caused by the pallet edge picking of the forklift is thoroughly solved, the maintenance rate of the pallet is reduced by about 70%, the average service life is prolonged by more than half, and the energy-saving and environment-friendly effects on improving the utilization rate are achieved.

Description

Pallet

Technical Field

The present invention relates to pallets.

Background

The pallet is usually made of wood, so the pallet is also called as a wood pallet, and the wood pallet is a goods final carrier commonly used in wharfs and freight transportation industries and is an essential tool for a forklift to transport goods in a field and for checking the goods in cooperation with customs.

At present, a wood pallet is formed by splicing a bottom layer plate and an upper layer wood plate, and a space for inserting fork teeth of a forklift is reserved between the two layers of wood plates, so that when goods are loaded on the pallet, the pallet and the goods on the pallet can be directly forked together by the forklift, and the wood pallet is a goods support commonly used in the wharf freight industry.

In addition to long-term damage and accidental impact damage of the pallet, the condition that a driver needs to slightly lift half of the front fork tooth by means of a small segment of front fork tooth and then take the pallet out by means of friction and then go deep into the fork tooth again is commonly caused when the driver lifts the side plate close to the fork tooth to pull the pallet out of the container with the goods or the fork tooth cannot completely enter the bottom of the pallet at a proper position due to small space. This operating condition is an unavoidable condition, with the result that the outermost bearing plate of the pallet is often subjected to excessive stress, causing the side plates of the pallet to be detached from the square wooden frames, resulting in the pallet being scrapped loose. Through research, the connection screw falls off due to stress is the most main damage factor.

Disclosure of Invention

The invention provides a pallet aiming at the problems that the existing wooden pallet is easy to damage and cannot meet the requirements of the horsehead and freight industry.

The technical scheme adopted by the invention for realizing the technical purpose is as follows: a pallet comprises two parallel square bars, at least one middle square bar arranged between the two parallel square bars and parallel to the two parallel square bars; uniformly distributing plates between the two parallel square bars to form an upper supporting surface and a lower supporting surface of the pallet; and four corners of the upper supporting surface and the lower supporting surface are respectively fastened by adopting reinforcing steel bars.

According to the invention, on the basis of a common wooden pallet, reinforcing steel bars are adopted to replace traditional wooden screws or iron nails, and the upper and lower transverse plates which are the most adjacent sides of the pallet are structurally improved, so that the problem of pallet looseness caused by the pallet edge picking of the forklift is thoroughly solved, the maintenance rate of the pallet is reduced by about 70%, the average service life is prolonged by more than half, and the energy-saving and environment-friendly effects on improving the utilization rate are achieved.

Further, in the pallet described above: the steel bar is in a frame shape formed by winding steel bars for common buildings, and is embedded into four corners of the upper supporting surface and the lower supporting surface.

Further, in the pallet described above: the specification of the square bars and the middle square bars is 120 multiplied by 10 multiplied by 6cm³。

Further, in the pallet described above: the specification of the plate is 150 multiplied by 15 multiplied by 2cm³(ii) a The distance between adjacent sheets was 20 cm.

The present invention will be further described with reference to the accompanying drawings and detailed description.

Detailed Description

Embodiment 1, this embodiment is a pallet which is widely used in freight terminals, warehouses, and the like and facilitates manual operation of a forklift, and as shown in fig. 1, 2, and 3, the pallet 100 of this embodiment is formed by an upper supporting surface 10 and a lower supporting surface 20 which are formed by two parallel square bars 31 and a plate material 40 nailed between the two parallel square bars 31, in this embodiment, three middle square bars 30 are further provided between the two parallel square bars 31, one middle square bar 30 is provided in the middle of the two parallel square bars, and one middle square bar 30 is further provided between the middle square bar 30 and the square bar 31 in the middle. In this embodiment, the four corners of the upper support surface 10 and the lower support surface 20 are fastened by reinforcing bars 50, respectively. The reinforcing bars 50 are formed in a frame shape by winding reinforcing bars for general construction, and are inserted into four corners of the upper and lower supporting

surfaces

10 and 20, as shown in fig. 2. In this embodiment, the square bars 31 and the middle square bars 30 are made of the same square material and have a specification of 120 × 10 × 6cm³. On each of the upper and

lower support surfaces

10 and 20 are 7 sheets 40 of material to form a pallet 100, in this embodiment the sheet 400 is 150 x 15 x 2cm in size³(ii) a The distance between adjacent plates is 20cm。

In this example, the pallet was prepared as follows:

1. shallow grooves or hot-ironed shallow grooves are dug at the four corner panels.

2. And (4) pre-lengthening and cutting the round steel, and bending to complete the fork shape.

3. The four-corner drill guide hole is 10-15% smaller than the diameter of the steel bar, and allows rapid hot drill forming.

4. The hot bar fork is 200 degrees to 150 degrees.

5. The two-head fork is pressed into the guide hole, the upper edge of the two-head fork is compacted and attached to the embedded groove, and the upper reinforcing steel bar is hammered to be embedded into the upper embedded groove.

6. Turning over the clamping plate, bending the two ends into hooks, buckling the hooks into the lower plate embedding grooves, cooling, and tightly buckling the upper and lower boards and the square beams through the contraction of the reinforcing steel bars to finish the process.

7. Other process requirements are the same as for a normal wooden pallet.
