Description

Technical Field

[0001] This utility model relates to a storage rack, specifically a storage rack with internal layered stacking suitable for storing and retrieving metal sheets, belonging to the field of storage rack technology. Background Technology

[0002] Factories typically store sheet metal such as steel and copper plates directly on the warehouse floor, stacking them sheet by sheet. This direct stacking method presents significant problems, especially for thin sheet metals with relatively small dimensions and thickness. Because sheet metals come in various specifications and thin sheets are relatively soft and easily warped, not only is storing and retrieving each batch inconvenient and inventory checking difficult, but also the placement and securing of these sheets is unsafe. Existing technologies include drawer-type storage racks for thin sheet metals. While these racks allow for layered and categorized stacking, the drawer-type structure has a cantilever problem when the pallets are pulled out, limiting their load-bearing capacity. To increase load-bearing capacity, it is usually necessary to increase the rigidity of the pallets themselves and equip them with a complex sliding rail system with sufficient cantilever support rigidity, resulting in high costs. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a storage rack with internal layered stacking, which can increase the load-bearing capacity of the storage pallet without increasing the rigidity of the storage pallet itself or the complexity of the slide rail system. It is particularly suitable for storing thin metal sheets with relatively small dimensions and thickness.

[0004] To achieve the above objectives, this internally layered stacking storage rack includes a frame, which is a cuboid frame structure including a long side, a wide side, and a high side. The front side of the frame corresponding to the long side of the cuboid frame structure has an open storage pallet inlet and outlet. The storage pallet inlet and outlet are provided with door frames that are symmetrically arranged on the left and right and respectively hinged to the frame. The two door frames together form a storage door that can be opened and closed from the left and right. The left and right sides of the frame are equipped with multiple inner guide rails arranged in pairs and in layers. The inner guide rails are horizontally arranged in the front-to-back direction and are fixedly connected to the frame. The inner sides of the two door frames are equipped with outer guide rails arranged in layers, corresponding to the positions of the inner guide rails. The outer guide rails are horizontally arranged and are fixedly connected to the door frames. When the two door frames are fully closed, the outer guide rails are perpendicular to the inner guide rails. When the two door frames are fully open, the outer guide rails are aligned with the inner guide rails. Multiple storage pallets are arranged in layers inside the frame, and the storage pallets are mounted on the inner guide rails through a translational connection mechanism that cooperates with the inner guide rails.

[0005] As a further improvement of this utility model, the bottom of the door frame is provided with support rollers that contact the ground.

[0006] As a further improvement of this utility model, the length of the outer guide rail is greater than the length of the inner guide rail.

[0007] As a further improvement of this utility model, the ends of the inner guide rail and the outer guide rail are respectively provided with translational limiting mechanisms.

[0008] As a further improvement of this utility model, a pallet handle is fixedly provided on the storage pallet at the position of the storage pallet inlet and outlet corresponding to the frame.

[0009] As a further improvement of this utility model, a door frame handle is fixedly provided on the door frame.

[0010] As a further improvement of this utility model, a cargo identification nameplate is provided on the storage pallet at the position of the storage pallet inlet corresponding to the frame.

[0011] As a further improvement of this utility model, positioning baffles are provided at the four edges of the top plane of the storage pallet.

[0012] As a further improvement of this utility model, lifting lugs are fixedly provided on the frame.

[0013] As one embodiment of this utility model, the translational connection mechanism is a translational connection structure including a guide wheel, which is a single-rimmed wheel or a double-rimmed wheel.

[0014] Compared to existing technologies, this internally layered stacking storage rack allows the outer guide rail to align with the inner guide rail when the door frame is fully opened. This enables the storage pallet to be moved from the inner guide rail to the outer guide rail via a sliding connection mechanism for storing, retrieving, or hoisting goods. The outer guide rail also supports the weight of the storage pallet, preventing it from being suspended and increasing its load-bearing capacity. After storing or hoisting goods, the pallet can be pushed back into the rack and the door frame closed. This internally layered stacking storage rack increases the load-bearing capacity of storage pallets without increasing their rigidity or the complexity of the slide rail system, making it particularly suitable for storing thin metal sheets with relatively small dimensions and thickness.

[0016] In the diagram: 1. Frame, 2. Door frame, 3. Inner guide rail, 4. Outer guide rail, 5. Storage pallet. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings (the following description takes the movement direction of the storage pallet 5 as the front-to-back direction).

[0018] like Figure 1 , Figure 2 As shown, the internally layered stacking storage rack includes a frame 1, which is a cuboid frame structure including a long side, a wide side, and a high side. The front side of the frame 1, corresponding to the long side of the cuboid frame structure, is provided with an open storage pallet inlet and outlet. The storage pallet inlet and outlet are provided with door frames 2 that are symmetrically arranged on the left and right and are respectively hinged to the frame 1. The two door frames 2 together form a storage door that can be opened and closed from the left and right.

[0019] Multiple inner guide rails 3 are provided on the left and right sides of the frame 1, which are arranged in pairs and in layers. The inner guide rails 3 are arranged horizontally in the front-back direction and are fixedly connected to the frame 1. On the inner sides of the two door frames 2, corresponding to the positions of the inner guide rails 3, there are outer guide rails 4 arranged in layers. The outer guide rails 4 are arranged horizontally and are fixedly connected to the door frames 2. When the two door frames 2 are fully closed, the outer guide rails 4 are perpendicular to the inner guide rails 3. When the two door frames 2 are fully open, the outer guide rails 4 are aligned with the inner guide rails 3.

[0020] Multiple storage pallets 5 are arranged in layers inside the frame 1, and the storage pallets 5 are mounted on the inner guide rail 3 through a translation connection mechanism that cooperates with the inner guide rail 3. The translation connection mechanism can be a translation connection structure including a guide wheel structure, or a translation connection structure including a guide slide rail, or other translation connection structures.

[0021] When using this internally layered stacking storage rack, after fully opening door frame 2, as follows: Figure 2 As shown, the outer guide rail 4 can be docked with the inner guide rail 3. Therefore, the storage pallet 5 can be moved to the outer guide rail 4 via the inner guide rail 3 through the translation connection mechanism for the storage, retrieval or hoisting of goods. The outer guide rail 4 can bear the weight of the storage pallet 5, thereby avoiding the storage pallet 5 being in a suspended state and increasing the load-bearing capacity of the storage pallet. After the storage, retrieval or hoisting of goods is completed, the storage pallet 5 can be directly pushed into the frame 1 and the door frame 2 can be closed.

[0022] When the storage pallet 5 moves onto the outer guide rail 4, in order to effectively support the weight of the storage pallet 5, as a further improvement of this utility model, the bottom of the door frame 2 may be provided with support rollers that contact the ground.

[0023] To enable the storage pallet 5 to be completely moved to the outside of the frame 1, as a further improvement of this utility model, the length of the outer guide rail 4 can be greater than the length of the inner guide rail 3.

[0024] To prevent the storage pallet 5 from detaching from the guide rail, as a further improvement of this utility model, the ends of the inner guide rail 3 and the outer guide rail 4 are respectively provided with translational limiting mechanisms. The translational limiting mechanisms can be other limiting and blocking structures such as limiting blocks or limiting baffles to prevent the storage pallet 5 from detaching from the guide rail.

[0025] To facilitate pulling out or pushing in the storage pallet 5, as a further improvement of this utility model, a pallet handle is fixedly provided on the storage pallet 5 at the position corresponding to the storage pallet inlet and outlet of the frame 1.

[0026] To facilitate opening or closing the door, as a further improvement of this utility model, a door frame handle is fixedly provided on the door frame 2.

[0027] To facilitate the identification of goods, as a further improvement of this utility model, a goods identification nameplate is provided on the storage pallet 5 at the position corresponding to the storage pallet inlet and outlet of the frame 1.

[0028] For thin metal plates, in order to facilitate stacking and positioning, as a further improvement of this utility model, positioning baffles are provided at the four edges of the top plane of the storage pallet 5.

[0029] To facilitate the hoisting and relocation of the internally layered storage racks, as a further improvement of this utility model, lifting lugs are also fixedly provided on the frame 1.

[0030] As one embodiment of this utility model, the translation connection mechanism is a translation connection structure including guide wheels, and the guide wheels are single-flanged wheels or double-flanged wheels that can laterally position the storage pallet 5 in the left and right directions.
