Description

Technical Field

[0001] This utility model relates to the field of shelf reinforcement, specifically a heavy-duty shelf upright corner protector. Background Technology

[0002] For heavy-duty racking in warehouses and logistics centers, structural sturdiness and stability are the only crucial indicators. However, their working environment frequently exposes them to impacts from forklifts and other equipment. These impacts typically occur at low points near the ground, and their frequency inevitably damages the bottom of the racking uprights, causing surface dents, weld cracks, and even tilting and deformation. Corner guards are components specifically designed to address this problem. Corner guards are typically fixed to the bottom of the racking uprights with fasteners or welding to absorb impact forces and prevent the uprights from deforming, bending, or breaking due to collisions with forklifts or pallet trucks. Metal corner guards offer the highest level of protection. Common metal corner guards employ U-shaped and L-shaped designs. U-shaped corner guards "hold" the bottom of the upright, while L-shaped corner guards have a right-angle bend and only cover one side of the upright. However, both types of corner guards have limited impact resistance. After several impacts or severe impacts, the impact will still be transmitted to the upright, rendering the existing corner guards' impact protection ineffective. Utility Model Content

[0003] The purpose of this utility model is to provide a heavy-duty shelf upright corner protector. Its trapezoidal forward-protruding corner protector design can absorb most of the impact force through its own deformation, reduce the force transmitted to the upright, and thus improve the protection capability.

[0004] To achieve the above objectives, this utility model employs the following technical solution: A heavy-duty shelving upright corner protector includes an upright guard plate. The guard plate comprises a flat plate and an inclined plate of one-piece structure. The inclined plate is symmetrically arranged on both sides of the flat plate, forming an isosceles trapezoidal protruding structure. The inclined plate forms an angle of 45 degrees to 70 degrees with the flat plate. The flat plate is parallel to the outer facade of the shelving upright.

[0005] The flat plate and the inclined plate form an angle of 60±5 degrees.

[0006] The outer side of the flat plate is provided with an arc-shaped curved plate, which forms a 90-degree curved structure with the flat plate by arc bending.

[0007] The bottom side of the inclined plate is provided with an outwardly folded mounting plate. The mounting plate extends horizontally and is set perpendicular to the inclined plate. A first mounting hole is passed through the mounting plate, and a fastener is fitted in the first mounting hole.

[0008] A stiffening plate is fixed in the middle of the flat plate between the inclined plates. The stiffening plate extends vertically and is perpendicular to the flat plate. A wing plate is fixed on the side of the stiffening plate away from the flat plate and extends vertically to it. The wing plate is fixed to the shelf upright by fasteners.

[0009] A stiffening plate is fixed in the middle of the flat plate between the inclined plates. The stiffening plate extends vertically and is perpendicular to the flat plate. A wing plate is provided on the side of the stiffening plate away from the flat plate and extends vertically relative to the stiffening plate. A vertically extending slot is provided in the center of the side of the wing plate close to the flat plate. The side of the stiffening plate is movably inserted into or slidably connected to the slot. The wing plate is used to fix to the column.

[0010] It also includes multiple independently set strips, which are arranged parallel to the flat plate. Multiple ribs are fixedly welded to both sides of the wing plate. Long bolts pass through the ribs, and the other end of the long bolts passes through both ends of the strip plate and is fitted with several nuts.

[0011] The top side of the flat plate is fixedly connected to a folded plate that extends horizontally and perpendicularly to it. The folded plate is located between two inclined plates. The side of the folded plate away from the flat plate has a right-angle structure that bends downwards by 90 degrees to form a "┌" shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This corner protector protrudes forward in a trapezoidal protective structure, creating a buffer space between it and the fixed post. This design allows the corner protector to absorb most of the impact energy during a collision through deformation, thus reducing the force transmitted to the post. The trapezoidal structure offers good stability and can better withstand impacts from different directions. It also shifts the impact protection forward, keeping the danger away from the post. Furthermore, this structure can be uniformly installed in front of the post regardless of left or right orientation, without needing to consider interference with other structures, greatly improving its adaptability.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0022] Unless otherwise specified, the instruments, reagents, and materials used in the following embodiments are all conventional instruments, reagents, and materials already available in the prior art and can be obtained through legitimate commercial channels. Unless otherwise specified, the experimental methods and detection methods used in the following embodiments are all conventional experimental methods and detection methods already available in the prior art. Example 1:

[0023] This corner protector improves upon the L-shaped corner protector by modifying the shape of the impact-bearing portion. Its structure is as follows: The protective plate has a trapezoidal cross-section and extends vertically. The protective plate is the main body of the protection. The protective plate includes a flat plate 1 located in the center and inclined plates 2 located on both sides of the flat plate 1 and symmetrically arranged relative to the flat plate 1. The flat plate 1 and the inclined plates 2 form an angle of about 60 degrees, so that the inclined plates 2 extend outward at a large angle from both sides of the flat plate 1. The inclined plates 2 and the flat plate 1 together form a convex structure with an isosceles trapezoidal cross-section.

[0024] This raised design is a breakthrough compared to existing corner protectors. Existing corner protectors are designed to be fitted directly against the shape and position of the uprights for protection, with limited and consistent gaps between the corner protector and the uprights. They are basically fixed to the uprights, so the impact force is directly transmitted to the uprights, causing the uprights to deform or be damaged, thus affecting the stability of the shelving.

[0025] In addition, the limited location for use is also a problem with corner protectors. L-shaped corner protectors need to be installed at the corner of the column, so the installation direction needs to be considered. U-shaped corner protectors will also interfere with the shelves and connecting beams, resulting in a strong limitation on the specific installation location.

[0026] This guard plate, based on its symmetrical isosceles trapezoidal protrusions, creates an outwardly expanding support space with the column. This design absorbs most of the impact energy during a collision through the deformation of the corner guards, thereby reducing the force transmitted to the column. The trapezoidal structure offers good stability and can better withstand impacts from different directions. It also shifts the impact protection forward, keeping the danger away from the column.

[0027] In addition, this structure uses symmetrical inclined plate 2 for diffusion support. The installation position is not distinguished by left or right and can be uniformly installed in front of the column. There is no need to worry about interference with other structures, which greatly improves adaptability.

[0028] The outer side of the flat plate 1 is provided with an arc-shaped curved plate 3. The curved plate 3 forms a 90-degree curved structure with the flat plate 1 through an arc bend, thereby causing the outer side of the inclined plate 2 to fold outward and contact the upright or shelf beam through the curved surface of the curved plate 3. When the corner protector is impacted, the two sides of the inclined plate 2 contact the shelf through the curved plate 3. In the event of deformation, the contact position is smooth and can guide the deformation outward, without causing local damage to the upright.

[0029] The bottom side of the inclined plate 2 is provided with an outwardly folded mounting plate 4. The mounting plate 4 extends horizontally and is set perpendicular to the inclined plate 2. A first mounting hole 5 passes through the mounting plate 4. A fastener is fitted in the first mounting hole 5. The fastener is an expansion bolt or a regular bolt, which is nailed downward to the ground to fix the corner guard, depending on the site conditions.

[0030] The flat plate 1, inclined plate 2, mounting plate 4, and bent plate 3 are all integral structures, formed by metal bending or by welding.

[0031] Based on the raised corner design, a trapezoidal space exists between the corner protector and the column. To improve support strength and fixation, a vertically extending stiffening plate 6 is provided in the center of the upper half of the plate 1. The stiffening plate 6 is located between two inclined plates 2. A wing plate 7 is fixed to the side of the stiffening plate 6 away from the plate 1, perpendicular to it and extending vertically. Second mounting holes 8 are provided on both sides of the wing plate 7, symmetrically arranged relative to the stiffening plate 6. The spacing of the second mounting holes 8 is adapted to the spacing of the mounting holes on the column, or twice the spacing of the second mounting holes 8 is adapted to the spacing of the mounting holes on the column, thereby facilitating the reinforcement of the upper part of the guard plate to the column with fasteners.

[0032] This corner protector design, through the improved trapezoidal support shape, breaks through the limitation of existing L-shaped and U-shaped corner protectors that can only be close to the column for wrapping protection. It can protrude from the front side of the bottom of the column for enhanced protection, improve the life of storage equipment, and the upper part can be installed on the front side of any column, making it extremely versatile. Example 2:

[0033] The corner protector in this example also adopts a basic integrated structure of flat plate 1, inclined plate 2 and curved plate 3, and a horizontally outwardly folded mounting plate 4 is also provided on the bottom side of inclined plate 2.

[0034] For supporting the upper part of the corner protector, a flanged structure is adopted. A folded plate 13, perpendicular to and extending horizontally, is fixedly connected to the top side of the plate 1. The folded plate 13 is located between two inclined plates 2. The side of the folded plate 13 away from the plate 1 has a right-angle structure that bends downwards by 90 degrees to form a "┌" shape, and the right angle of the folded plate 13 also adopts an arc-shaped bending structure. The contact with the column is smooth.

[0035] The corner protector is fixed at the bottom by mounting plate 4, and combined with folding plate 13 at the top to form a support between the corner protector and the column, reducing impact deformation and enabling the corner protector to be used for a longer time. Example 3:

[0036] The corner protector in this example also adopts a basic integrated structure of flat plate 1, inclined plate 2 and curved plate 3, and a horizontally outwardly folded mounting plate 4 is also provided on the bottom side of inclined plate 2.

[0037] Considering that other components may be loaded on the column, such as tie rods, crossbeams, lining plates, shelves, etc., in order to reinforce the upper part of the corner guard, the plate 1 is provided with a stiffening plate 6 in the middle between two inclined plates 2. The stiffening plate 6 extends vertically and is set perpendicular to the plate 1. The width of the wing plate 7 is adapted to the width of the column. The stiffening plate 6 has a wing plate 7 on the side away from the flat plate 1. Two strip plates are fixedly welded to the center of the wing plate 7 on the side closer to the flat plate 1. The two strip plates are arranged side by side to form a slot 9. The width of the slot 9 is adapted to the thickness of the stiffening plate 6. The side of the stiffening plate 6 is movably inserted into the slot 9. Multiple reinforcing hoops 12 are fixedly welded to both sides of the wing plate 7. The reinforcing hoops 12 are made of bent steel bars welded to both sides of the wing plate 7. Long bolts 11 pass through the reinforcing hoops 12. The long bolts 11 are located on both sides of the column. It also includes multiple independently set strip plates 10. The two ends of the strip plates 10 are respectively provided with through holes that cooperate with the long bolts 11. The long bolts 11 are used to enclose and fix the column on both sides and inside the column through nuts and strip plates 10, so as not affected by the main structure of the rack and can be fixed to the column in a universal way.

[0038] In this structure, the fin plate 7 is the same width as the column. The transmission of impact force is completed through the flat plate 1 (sloping plate 2) - stiffener 6 - fin plate 7. The impact is fully absorbed by the deformation of the stiffener 6 and the main body of the guard plate. At the same time, the slot 9 can strengthen the stiffener 6 and improve its strength.

[0039] With the pluggable fin plate 7, the fin plate 7 can be fixed to the front side of the column first, and then the corner guard rib plate 6 can be inserted into the column and the corner guard can be fixed to the front side of the column by the mounting plate 4. This method can fully expose the position of installation and fastening operation, which is convenient for operation, and can simplify maintenance and replacement by replacing the guard plate part (retaining the long bolt 11 and fin plate 7).
