Detailed Implementation

[0018] Example 1: Please refer to Figures 1-4 This embodiment is a pallet 100, which includes a supporting base frame 1, a pair of end support components 2 disposed on the supporting base frame 1 and located at both ends in the long side direction, and a plurality of middle support components 3 disposed on the supporting base frame 1 and located between the two end support components 2; the end support components 2 are mounted on the supporting base frame 1 in an adjustable position along the long side direction.

[0019] The pallet 100 is adjustable in length by mounting the end support assembly 2 on the support base frame 1 in an adjustable position along the long side.

[0020] To achieve adjustable dimensions of the pallet 100 in the short-side direction, this embodiment optimizes the structure of the end support assembly 2 and the middle support assembly 3. Specifically, both the end support assembly 2 and the middle support assembly 3 include a short-side support beam 21 / 31 extending along the short-side direction, an end fixed support seat 22 / 32 fixedly disposed at one end of the short-side support beam 21 / 31, and an end movable support seat 23 / 33 disposed at the other end of the short-side support beam 21 / 31 whose position can be adjusted along the short-side direction.

[0021] The pallet 100 is adjustable in the short-side direction by means of the adjustable end support seats 23 / 33 mounted on the short-side support beams 21 / 31. This allows the pallet 100 to be adjusted in both the long and short sides, thus meeting the requirements for carrying materials of various sizes.

[0022] The supporting base frame 1 includes at least two parallel long-side support beams 11 extending along their long sides, and a pair of short-side connecting rods 12 connecting the ends of all the long-side support beams 11 together to form a rectangular frame structure. The two short-side connecting rods 12 are located at both ends of the long-side support beams 11 and extend along their short sides, connecting all the long-side support beams 11 together. In this embodiment, two long-side support beams 11 are provided, serving as the main support beams of the pallet 100. In other embodiments, three or more long-side support beams 11 may be provided. The short-side connecting rods 12 can be fixedly installed to the long-side support beams 11 by bolting, welding, or other fixed connection methods. The supporting base frame 1, with its rectangular frame structure formed by the long-side support beams 11 and the short-side connecting rods 12, improves the overall structural integrity and strength of the supporting base frame 1.

[0023] To enable the position of the end support component 2 to be adjustable, several first threaded holes 111 are provided in the designated sections at both ends of the long side support beam 11 along the long side direction. A horizontal first connecting plate 24 is provided at the bottom of the short side support beam 21. The first connecting plate 24 is provided with a first mounting through hole 241. By screwing the screw through the first mounting through hole 241 into the first threaded hole 111, the end support component 2 is locked and fixed on the support base frame 1. By screwing into different first threaded holes 111, the position of the end support component 2 can be adjusted.

[0024] To improve the installation firmness of the end support assembly 2 on the support base frame 1, the first connecting plate 24 extends horizontally out of both sides of the short side support beam 21, and the first mounting through hole 241 is provided on both sides of the extended section. The end support assembly 2 is locked and fixed from both sides of the short side support beam 21 by two screws, and the end support assembly 2 is provided at both ends of the end support assembly 2, so that the two ends of the end support assembly 2 are respectively fixedly installed on the long side support beam 11.

[0025] To enable the adjustable position of the end movable support 23 / 33 on the short side support beam 21 / 31, a number of second threaded holes 25 / 35 are arranged along the short side in a designated section at one end of the short side support beam 21 / 31. A second connecting plate 231 / 331 is provided at the bottom of the end movable support 23 / 33, and a second mounting hole 2311 / 3311 is provided on the second connecting plate 2311 / 3311. By screwing a screw through the second mounting hole 2311 / 3311 and into the second threaded hole 25 / 35, the end movable support 23 / 33 is locked and fixed on the short side support beam 21 / 31. By screwing into different second threaded holes 25 / 35, the position of the end movable support 23 / 33 can be adjusted.

[0026] In this embodiment, the two ends of the short side support beam 31 in the middle support assembly 3 are welded and fixed to the long side support beam 11.

[0027] To improve the overall strength and service life of the pallet, the pallet in this embodiment is an iron pallet, that is, the supporting bottom frame 1, the end supporting components 2 and the middle supporting components 3 are all made of iron.

[0028] Since the pallet 100 is made of iron, its overall weight will increase. In order to reduce the overall weight of the pallet 100, in this embodiment, the long side support beam 11, the short side support beams 21 / 31 and the short side connecting rod 12 are preferably hollow structures.

[0029] Since the long-side support beam 11 and the short-side support beams 21 / 31 are hollow structures, the thickness of their top profiles is insufficient to form an effective threaded hole structure. Therefore, in order to achieve the threaded hole structure, in this embodiment, a first mounting plate 13 extending along the long side direction is fixedly provided on the upper surfaces of both ends of the long-side support beam 11, and a plurality of first threaded holes 111 arranged along the long side direction are provided on the first mounting plate 13. The top profile body of the long-side support beam 11 is provided with clearance through holes (not shown in the figure) corresponding one-to-one with the positions of the first threaded holes 111, so as to allow for the insertion of clearance screws. A second mounting plate 26 / 36 extending along the short side direction is fixedly provided on the upper surface of one end of the short-side support beam 21 / 31, and a plurality of second threaded holes 25 / 35 arranged along the short side direction are provided on the second mounting plate 26 / 36. The top profile body of the short-side support beam 21 / 31 is provided with clearance through holes (not shown in the figure) corresponding one-to-one with the positions of the second threaded holes 25 / 35, so as to allow for the insertion of clearance screws.

[0030] When the pallet 100 carrying materials is moved to the operating station, there may be situations where its position needs to be precisely positioned. To facilitate the pallet positioning mechanism on the operating station in positioning the pallet 100, this embodiment has positioning slots 112 on the side profile of the long side support beam 11, so that the pallet positioning mechanism can position the pallet horizontally by inserting positioning blocks into the positioning slots 112. In this embodiment, a total of four positioning slots 112 are provided on the support base frame 1 to achieve precise positioning in the long and short side directions. In other embodiments, five or more positioning slots 112 may be provided.

[0031] In some applications, the pallet 100 carries materials that need to be transported on a roller conveyor line to multiple workstations for related operations. Since the pallet 100 is made of iron and the materials it carries are generally heavy, prolonged contact and friction between the iron pallet 100 and the roller conveyor line can easily wear down the conveyor rollers, shortening their lifespan and increasing conveying costs. To address this issue, a pad 14 made of nylon is installed at the bottom of the long-side support beam 11. This pad 14 contacts the conveyor roller, reducing wear. Later replacement only requires replacing the pad 14, not the roller itself, thus lowering conveying costs. Furthermore, the two downward-facing ends of the pad 14 are chamfered to reduce impact on the rollers.

[0032] To improve the reliability of material support and prevent central collapse due to insufficient support in the middle area, this embodiment further optimizes the structure of the end support assembly 2 and the middle support assembly 3. Specifically, in the end support assembly 2, at least one intermediate fixed support seat 27 is fixedly installed on the short side support beam 21 in the middle section. An intermediate movable support seat 28 is provided between the intermediate fixed support seat 27 and the end movable support seat 23, and / or between the intermediate fixed support seat 27 and the end fixed support seat 22. The intermediate movable support seat 28 is adjustable along the short side direction on the short side support beam 21, and the adjustable position is achieved in the same way as the adjustable position of the end movable support seat 23. In the middle support assembly 3, at least one intermediate movable support 38 is provided on the short side support beam 31 between the end fixed support 32 and the end movable support 33. The intermediate movable support 38 is provided on the short side support beam 31 with adjustable position along the short side direction. The position adjustment is achieved in the same way as the position adjustment of the end movable support 33.

[0033] In this embodiment, intermediate movable supports 28 are provided between the intermediate fixed support 27 and the end movable support 23, and between the intermediate fixed support 27 and the end fixed support 22. There are two intermediate movable supports 38 on the middle support assembly 3, which are respectively located close to the end fixed support 32 and the end movable support 33.

[0034] The intermediate movable support base 28 / 38 and the intermediate fixed support base 27 provide multi-point support for the central area of ​​the material, improving the reliability and safety of material support. The adjustable position design of the intermediate movable support base 28 / 38 allows for adjustments to accommodate materials of various sizes and specifications.

[0035] Both the end fixed support 22 / 32 and the middle fixed support 27 are welded and fixed to the short side support beam 21 / 31.

[0036] In this embodiment, the top of the end fixed support 22 / 32, the end movable support 23 / 33, the middle fixed support 27, and the middle movable support 28 / 38 are all provided with support pads 29 / 39 for contacting the material to prevent damage or scratches to the material surface.

[0037] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
