Description

Technical Field

[0001] The utility model relates to the field of photovoltaic component packaging and transportation, in particular to a pallet and a photovoltaic component transportation device. Background Art

[0002] In the photovoltaic module packaging and transportation industry, pallets are often used for packaging. After the PV modules are packaged, a forklift reaches under the pallet for conventional transport. The pallet consists of a frame on which the PV modules are placed, with square feet at the corners and bottom.

[0003] In the related art, during transshipment and transportation, the forklift's tines may hit the pallet's footrests. Since the footrests are glued and fixed to the frame body, if the footrests are hit by external force, it is easy to cause the footrest plates to tilt or break and fall off, which may cause the photovoltaic modules to be unstable at the least and cause the photovoltaic module packaging to collapse at the worst, causing the entire pallet of photovoltaic modules to tilt and thus affect the transportation of the modules; and, if the abnormality occurs in a transit warehouse or other place, since the transit warehouse generally does not have corresponding spare pallets, strapping tapes, strapping machines and other materials, it is very likely that the entire pallet of photovoltaic modules cannot be transshipped and can only be unpacked and sorted, which increases the difficulty of the operation.

[0004] Therefore, how to improve the reliability of the pallet is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0005] The purpose of the utility model is to provide a pallet and photovoltaic module transportation device, which can effectively avoid the risk of the foot pier in the pallet falling and improve the reliability of the pallet.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0027] The core of the utility model is to provide a pallet and a photovoltaic module transportation device, which can improve the reliability of photovoltaic module installation and transportation and reduce the risk of collision and damage to the foot piers in the pallet.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a specific embodiment of the pallet provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the structure of the supporting foot pier in the tray shown.

[0030] In this embodiment, the tray comprises:

[0031] The frame body 1 is provided with a bearing surface for bearing photovoltaic modules, and the bottom of the frame body 1 is provided with a receiving space for inserting the fork tines of a forklift;

[0032] A plurality of supporting foot piers 2 are installed on the frame body 1;

[0033] Furthermore, the supporting foot pier 2 includes a supporting inner shaft 21 and a circular ring component 22 . The circular ring component 22 is rotatably sleeved on the outer portion of the supporting inner shaft 21 .

[0034] Specifically, in order to ensure the smooth rotation of the circular ring component 22, the height of the circular ring component 22 should be less than the height of the supporting inner shaft 21. In the absence of an applied force, the circular ring component 22 is on the same surface as the supporting inner shaft 21 under the action of gravity. When subjected to a certain force, the circular ring component 22 will rotate. At the same time, the height can be appropriately adjusted to adapt to the position changes of the fork teeth in the horizontal and vertical directions, to eliminate the applied force, and to avoid impact damage to the supporting foot pier 2 during transportation.

[0035] The pallet improves the structure of the support foot 2 and utilizes the relative rotation between the support inner shaft 21 and the annular component 22. When the fork tine of the forklift hits the support foot 2 first when inserting into the accommodating space, the annular component 22 can reduce a part of the force from the fork tine during the rotation process, and guide the force generated by the collision to be dispersed. When the linear force of the fork tine is too large, the annular component 22 will be damaged without damaging the support inner shaft 21. The annular component 22 can protect the support inner shaft 21 and protect the support inner shaft 21 from damage as much as possible, thereby reducing the impact on the overall load-bearing capacity of the pallet. At the same time, since the annular component 22 can rotate relative to the support inner shaft 21, the annular component 22 can play a certain guiding role in the moving direction of the fork tine.

[0036] In some embodiments, the frame body 1 is square, and the supporting feet 2 are located at the four corners of the frame body 1 to effectively support the frame body 1 .

[0037] In some embodiments, the frame body 1 includes an upper frame 11 and a side frame 12. The surface of the upper frame 11 constitutes a load-bearing surface for placing photovoltaic components. The side frame 12 is located on the side of the upper frame 11, and can be located on the side of the upper frame 11, or at the bottom of the upper frame 11 near the side. Specifically, the length of the side frame 12 should be consistent with the length of the upper frame 11, so that the side frame 12 can effectively support the entire upper frame 11. The support foot 2 is arranged at both ends of the side frame 12 and does not exceed the upper frame 11, so that the support foot 2 can effectively support the upper frame 11; specifically, a cavity 121 for accommodating the support foot 2 is provided in the side frame 12, and the support inner shaft 21 and the circular ring component 22 are both located in the accommodating space to facilitate the installation of the support foot 2. The cavity 121 faces the accommodating space, that is, the support foot 2 may only be touched when the fork tines of the forklift are inserted into the accommodating space.

[0038] In some embodiments, the upper frame 11 includes a plurality of frame strips 111 . The frame strips 111 are arranged at intervals and in parallel, and are connected and fixed to each other via the side frames 12 .

[0039] In some embodiments, the side frame 12 includes an upper slat 122, a side slat 123, and a lower slat 124. The extension directions of the upper slat 122, the side slat 123, and the lower slat 124 are perpendicular to the extension direction of the frame slat 111. The upper slat 122 is connected to the frame slat 111, and the side slat 123 is connected to the side of the upper slat 122 and the lower slat 124 away from the accommodating space. The support foot 2 is installed between the upper slat 122 and the lower slat 124, that is, the upper part of the support foot 2 is fixedly connected to the upper slat 122, and the lower part of the support foot 2 is fixedly connected to the lower slat 124, to ensure the supporting force effect of the support foot 2. In the normal state, the annular component 22 stands on the surface of the lower slat 124. During the transportation of photovoltaic modules, if foreign objects such as forklift forks touch the part of the support foot 2 of the pallet, the annular component 22 will rotate.

[0040] In some embodiments, the side frame 12 includes a first side frame 12 and a second side frame 12, and the first side frame 12 and the second side frame 12 are respectively located on both sides of the upper frame 11 to ensure balanced force, and the cavities 121 of the first side frame 12 and the second side frame 12 are relatively arranged, that is, the cavities 121 of the first side frame 12 and the second side frame 12 are both facing the accommodating space, which is convenient for guiding the movement of the fork teeth and eliminating the force.

[0041] In some embodiments, the side frame 12 also includes a front baffle 125 and a rear baffle, which are respectively located at the front and rear ends of the extension direction of the side strips 123, and the cavity 121 is surrounded by the upper strips 122, the side strips 123, the lower strips 124, the front baffle 125 and the rear baffle, and the support foot pier 2 is arranged close to the front baffle 125 and the rear baffle; specifically, after installation, the support foot pier 2 is blocked by the upper strips 122, the side strips 123, the lower strips 124, the front baffle 125 or the rear baffle to ensure the reliability of the support foot pier 2 during normal use.

[0042] In some embodiments, the top of the supporting inner shaft 21 is glued and fixed to the bottom surface of the upper strip 122, and the bottom of the supporting inner shaft 21 is glued and fixed to the upper surface of the lower strip 124; and the outer diameter of the annular component 22 is ≤ the width of the upper strip 122, and the outer diameter of the annular component 22 is ≤ the width of the lower strip 124. The above arrangement is to avoid the size of the annular component 22 being too large, which affects the installation of the supporting inner shaft 21; that is, there are gaps between the annular component 22 and the front baffle 125 or the rear baffle, and between the annular component 22 and the side strips 123, which can ensure the smooth rotation of the annular component 22. Figure 2 The upper strip 122 and the lower strip 124 shown in FIG are only partial schematic views.

[0043] In some embodiments, the frame body 1 further includes an intermediate support member 13, which has the same extension direction as the side frame 12. The intermediate support member 13 is installed at the bottom middle position of the upper frame 11 and divides the accommodating space into two parts; the intermediate support member 13 not only plays a reinforcing role, but also divides the accommodating space into two parts, which can be adapted to the structure of the two fork tines of a forklift.

[0044] In some embodiments, a clearance fit is adopted between the inner wall of the annular component 22 and the outer surface of the supporting inner shaft 21, and the clearance is 1-2 mm. The clearance should not be too large, causing the annular component 22 to shake easily, nor too small, affecting the rotation of the annular component 22.

[0045] In some embodiments, the circular ring component 22 is a wooden circular ring component 22; specifically, the material of the circular ring component 22 is the same as the material of the support inner shaft 21, and can be processed from a material with a certain hardness. This setting is to have a certain impact resistance and is not easy to be damaged. At the same time, it rotates through the collision with the fork teeth, which is more conducive to the dissipation of the impact force, reduces damage to the support inner shaft 21, ensures the support effect of the support inner shaft 21, and thus ensures the installation and transportation reliability of the photovoltaic module.

[0046] The tray improves the shape and structure of the supporting foot pier 2 so that the supporting foot pier 2 can reduce the probability of being damaged by external force impact, and the double-layer structural protection significantly improves the impact resistance of the supporting foot pier 2 itself.

[0047] In addition to the above-mentioned pallet, the present invention also provides a photovoltaic module transport device including the above-mentioned pallet. For the structure of other parts of the photovoltaic module transport device, please refer to the relevant technology and will not be described in detail herein.
