Description

Technical Field

[0001] The present application relates to the technical field of storage structures, and in particular to a three-dimensional storage unit. Background Art

[0002] At present, the three-dimensional storage system is the most advanced storage method. The physical foundation of the three-dimensional storage system is composed of multiple stacked storage units, which can make full use of the vertical space in the warehouse. The existing storage units are composed of multiple supporting structures, and the bottom is mostly hollow. Although storage boards can be used to provide stable support for the stored goods, if the packaging of the goods is damaged during the transfer process, since most storage systems do not have visual observation capabilities, the goods placed in the storage units may continue to leak, especially for granular materials stored inside. After the materials leak out, they will not only shrink themselves, but also affect the storage units and goods below. Summary of the invention

[0003] The purpose of this application is to provide a three-dimensional storage unit with less mutual influence.

[0004] To achieve the above objectives, the present application provides a three-dimensional storage unit: comprising a pallet, the pallet being in the shape of an inverted quadrangular pyramid, a material receiving cavity being provided on the upper surface of the pallet, a clearance groove being provided on the front side of the pallet, the clearance groove extending downward from the upper surface of the pallet and passing through the material receiving cavity, a pair of left-right symmetrical brackets being fixedly connected to the upper surface of the pallet, the two brackets being respectively located on the left and right sides of the material receiving cavity, both ends of each of the brackets being fixedly connected to brackets, and the upper ends of the four brackets being fixedly connected to another pallet, which can catch materials leaked from the goods.

[0005] Preferably, the bracket comprises a bridging plate located outside the material receiving cavity, and a side surface of the bridging plate has a supporting plate located above the material receiving cavity for directly contacting a storage plate for goods.

[0006] As a preference, the upper surface height of the supporting plate is lower than the upper surface height of the bridging plate, and the supporting plate and the bridging plate are of equal length in the front-to-back direction, thereby increasing the contact area with the cargo rack and reducing local compressive stress.

[0007] As a preferred embodiment, the bottom inclined corners of the pallet are provided with fitting grooves located below the bracket, and there are two making way grooves, which are symmetrically arranged on the left and right and correspond to the forks of the palletizer.

[0008] As a preferred embodiment, an inwardly contracted groove is provided at the bottom of the tray, and the material thickness of the inner wall of the receiving cavity of the tray from the bottom surface to the outer side surface is uniform, so as to minimize unnecessary materials, thereby reducing the dead weight and improving the lightweight.

[0009] As a preferred embodiment, a diagonal bracket is fixedly connected between the two brackets located at the rear, which can effectively prevent the brackets from tilting.

[0010] As a preference, a crossbeam close to the upper end is fixedly connected between the two brackets located on the left side, and a crossbeam close to the upper end is fixedly connected between the two brackets located on the right side, so as to ensure the stability of the upper ends of the brackets.

[0011] As a preferred embodiment, a rib plate is fixedly connected between the bracket and the bridging plate, and a rib plate is fixedly connected between the bracket and the crossbeam, so as to improve the connection strength between the supporting structures.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By providing a tray structure with a material receiving cavity at the bottom of each storage unit, the stored goods can be caught when leakage occurs, thereby reducing material damage and avoiding impact on the storage unit below and the stored goods;

[0014] (2) By opening a clearance groove structure on the side of the pallet, the fork of the palletizer can be easily inserted into the receiving cavity, and the goods can be placed in the storage unit or taken out from the storage unit smoothly. The bracket with a stepped structure can reduce the movement of the placed goods. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] like Figure 1-8The three-dimensional storage unit shown in the figure comprises a tray 1 in the shape of an inverted quadrangular pyramid, the upper and lower surfaces of the tray 1 are both rectangular, a receiving cavity 101 is provided on the upper surface of the tray 1 for holding particles or debris that may fall from the upper package, and an inner shrinkage groove 103 is provided at the bottom of the tray 1 for making more space under the tray 1, while reducing the consumables of the tray 1 and reducing its own weight. The material thickness of the inner wall of the receiving cavity 101 of the tray 1 is uniform on the bottom and the outer side, that is, due to the shrinkage of the inner shrinkage groove 103, the inner wall of the receiving cavity 101 will also bulge upward A clearance groove 102 is provided on the front side of the pallet 1 for the fork of the palletizer to pass through. Since the palletizer usually has two forks, the number of the clearance grooves 102 is also two, and the two clearance grooves 102 are arranged symmetrically and correspond to the positions of the forks of the palletizer. The clearance groove 102 extends downward from the upper surface of the pallet 1 to avoid movement interference between the fork and the pallet 1. The clearance groove 102 passes through the receiving cavity 101, so the fork of the palletizer can be inserted into the receiving cavity 101, which is conducive to stably placing the package body directly above the pallet 1.

[0029] A pair of left-right symmetrical brackets 2 are fixedly connected to the upper surface of the tray 1 for directly contacting the storage plate under the packaging body. The two brackets 2 are respectively located on the left and right sides of the material receiving cavity 101. Specifically: the bracket 2 includes a bridge plate 201 located outside the material receiving cavity 101 for connecting other supporting structures. The side of the bridge plate 201 has a supporting plate 202 located above the material receiving cavity 101. As the main component providing support for the storage plate of the packaging body, the upper surface height of the supporting plate 202 is lower than the upper surface height of the bridge plate 201, that is, a stepped groove structure is formed between the upper surface of the supporting plate 202 and the inner side surface of the bridge plate 201 to prevent the storage plate of the packaging body from moving in the horizontal plane. The supporting plate 202 and the bridge plate 201 are of equal length in the front-to-back direction, and are slightly larger than the width of the storage plate of the packaging body in the front-to-back direction, so that the projection of the storage plate of the packaging body in the horizontal plane can be completely located within the material receiving cavity 101.

[0030] Both ends of each bracket 2 are fixedly connected with a bracket 3, all brackets 3 are vertical, and are usually made of hollow alloy square tubes, and ribs 4 are fixedly connected between the bracket 3 and the bridge plate 201 to improve the connection strength between the bracket 3 and the bridge plate 201. The upper ends of the four brackets 3 are commonly fixedly connected with another pallet 1, and the upper surface of the other pallet 1 also has the same support frame structure, which can increase the storage height layer by layer. The bottom inclined corners of the pallet 1 are provided with a fitting groove 104 located below the bracket 3, which is used to be plugged with the upper end of the bracket 3, and the plugging is usually welded. Fixed, can well ensure the connection stability between the upper and lower pallets 1, a diagonal frame 6 is fixedly connected between the two brackets 3 located at the rear, which is used to disperse the force of the bracket 3, and can effectively prevent the bracket 3 from tilting, so that the bracket 3 has higher compression and bending resistance. A crossbeam 5 close to the upper end is fixedly connected between the two brackets 3 located on the left, and a crossbeam 5 close to the upper end is fixedly connected between the two brackets 3 located on the right, and the crossbeam 5 is used to ensure the stability of the spacing at the upper ends of the brackets 3. A rib plate 4 is fixedly connected between the bracket 3 and the crossbeam 5, and similarly, it is used to improve the connection stability between the crossbeam 5 and the bracket 3.

[0031] Working principle: During installation, first fix the bracket 3 structure on the factory floor, directly fix it with cement casting, then fix the pallet 1 on the upper end of the bracket 3, and then fix the bracket 2, bracket 3, beam 5 and inclined bracket 6 on the upper surface of the pallet 1 in sequence, and weld the rib 4 at the required position, so that the storage unit of the lowest layer is configured. The storage unit of the lowest layer is suspended and away from the ground, which can effectively prevent the goods placed on the lowest layer from getting damp, and then continue to fix the pallet 1 on the upper end of the bracket 3 of the storage unit of the lowest layer, and stack the storage units upwards to form a three-dimensional storage space. When performing the storage operation, the fork of the palletizer lifts the storage board with the goods placed on it to the corresponding height of the target storage unit, and the fork By aligning and inserting it with the give way slot 102 of the pallet 1, the storage plate of the goods will be located directly above the supporting plate 202, and the fork will move down slightly so that the bottom of the storage plate contacts the upper surface of the supporting plate 202. The pressure exerted on the fork is connected by the supporting plate 202. After the goods are connected to the storage rack and placed, the fork can be withdrawn and follow the palletizer back to the initial position to wait. If the cargo packaging body is damaged and the smaller items contained inside leak out, they will fall into the receiving cavity 101 of the pallet 1, which will not affect the goods in other storage units and the leaked items can be easily found, so that the storage system has the function of making up, which improves the safety of cargo storage and effectively reduces the occurrence of missing storage objects.
