Description

Technical Field

[0001] This utility model relates to the field of beam hanging plate technology, and in particular to a beam hanging plate for warehouse racks. Background Technology

[0002] The beam hanger of a warehouse racking system is a crucial component, playing a key role in the overall structure. By definition, a warehouse racking beam hanger is a connector specifically designed to link the racking beams to the uprights. It typically has a specific shape and structure to precisely fit the beams and uprights. However, most existing warehouse racking beam hangers are fixed using welding or a single bolt, which has significant shortcomings. While welding provides a relatively strong connection, problems such as incomplete welds or false welds can easily lead to weld cracking under the weight of goods and frequent handling over long-term use. This can cause the beam-to-upright connection to loosen, affecting the overall stability of the racking. Similarly, the single bolt fixing method can result in the bolt loosening or even falling off due to long-term vibration and uneven stress, also weakening the connection between the beam and upright and increasing the risk of racking collapse. Instability in the racking system can not only damage goods but also endanger the lives of warehouse workers. Therefore, it is urgent to develop a more robust and reliable method for fixing crossbeam hangers in order to improve the safety and service life of warehouse racking. Utility Model Content

[0003] The purpose of this invention is to address the problem that a single fixing method in the background technology is not strong enough, and to propose a storage rack beam hanging plate.

[0004] The technical solution of this utility model: a storage rack beam hanging plate, including a hanging plate connecting plate, characterized in that: The hanging plate connecting plate is fixedly connected to the corner of the shelf beam by fastening bolts. A card is fixed to the front end of one side of the hanging plate connecting plate, and a control hanging plate is fixed to the rear end of the hanging plate connecting plate. A gap is formed between the card and the control hanging plate to accommodate the angle steel leg of the shelf. A connecting piece is fixed inside the control hanging plate. A square insertion hole is opened on the outer wall of the connecting piece. A clamping column is movably connected in the square insertion hole. A push rod is fixed on the inner side of the clamping column, and the outer side is used to press or insert the angle steel leg of the shelf. An L-shaped insertion slot is provided between the card and the upper part of the control panel. A long threaded rod is inserted through the insertion slot. The front end of the long threaded rod passes through the control panel, the angle steel leg of the shelf, and the card in sequence, and is limited by the front side of the card by a second nut. Its rear end extends to the outside of the control panel and is locked by a first nut. A tapered push wheel is fitted on the outer wall of the long threaded rod on the control panel. The tapered surface of the tapered push wheel abuts against the end of the push rod.

[0005] Optionally, the front end of the clamping column is provided with a one-way toothed groove group, and an extension piece is fixed on one side of the connecting piece, the end of which is connected to the one-way clamping teeth through a spring telescopic rod.

[0006] Optionally, the one-way locking teeth engage with the one-way tooth groove group, restricting the clamping column to move outward in only one direction.

[0007] Optionally, the end of the push rod that contacts the conical push wheel has a spherical structure, forming a sliding pair.

[0008] Optionally, the card is made of flexible aluminum alloy.

[0009] Optionally, when tightening nut number one, the long threaded rod moves axially backward, driving the tapered pusher to push the push rod so that the clamping column extends outward, while nut number two pushes the card to bend backward to clamp the angle steel leg of the shelf.

[0010] Optionally, the bending angle of the L-shaped insertion slot is 90°, which facilitates the disassembly and assembly of the long threaded rod.

[0011] Compared with the prior art, this application includes at least one of the following beneficial technical effects: First, this technology uses a hanging plate connecting plate to fix the corner of the shelf beam, and the L-shaped slot facilitates the disassembly and assembly of the long threaded rod, simplifying the installation and maintenance process. Second, the card is made of flexible aluminum alloy. When tightening the No. 1 nut at the rear end, the long threaded rod moves axially backward, pushing the No. 2 nut at the front end to bend the card backward, thereby tightly clamping it against the shelf angle steel leg to achieve initial clamping. At the same time, the conical push wheel on the long threaded rod pushes the push rod with the displacement, driving the clamping column to move outward and press against the shelf angle steel leg to increase support. With the meshing design of the one-way toothed groove group and the one-way clamping teeth, it can be ensured that the clamping column can only extend in one direction to prevent retraction due to operation, forming a firm anti-loosening protection. This design allows the card bending clamping and the clamping column pressing to work simultaneously, greatly enhancing the rigidity and stability of the overall connection and improving the long service life of the storage rack.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example: Figure 1 and Figure 2 As shown, this utility model proposes a storage rack beam hanger, including a hanger connecting plate 5, a card 4, a control hanging plate 3, a clamping column 7 assembly, and a long threaded rod 8. The hanger connecting plate 5 is fixedly connected to the corner of the rack beam 1 by fastening bolts to form a basic installation base. A card 4 is fixedly installed at the front end of one side of the hanger connecting plate 5, and a control hanging plate 3 is fixedly installed at the rear end. A gap is formed between the card 4 and the control hanging plate 3 to accommodate the rack angle steel leg 2, facilitating the insertion and positioning of the rack angle steel leg 2. An L-shaped insertion groove 6 is opened between the card 4 and the upper end of the control hanging plate 3, with a bending angle designed to be 90°. This groove structure facilitates the installation and removal of fasteners and the long threaded rod 8. The long threaded rod 8 is installed through the L-shaped insertion slot 6. Its front end passes through the control mounting plate 3, the angle steel leg 2 of the shelf inserted into the gap, and the card 4 in sequence, and is limited by the second nut 18 on the front side of the card 4. Its rear end extends to the outside of the control mounting plate 3 and is finally locked by the first nut 16. This basic structural design, especially the use of the L-shaped insertion slot 6, simplifies the installation and maintenance process, which is one of the advantages of this practical design.

[0021] At the same time, such as Figure 2 and Figure 3As shown, the double clamping structure of this utility model has a square insertion hole 9 on the connecting piece 17 fixed inside the control mounting plate 3. The clamping column 7, which is movably set in the square insertion hole 9, is the key structure for implementing double clamping. A push rod 14 is fixed on the inner side of the clamping column 7, and its end for applying outward pushing force is designed as a spherical structure. The outer side of the clamping column 7 directly acts on the angle steel leg 2 of the shelf for pressing or insertion fixation. The conical push wheel 11, which is sleeved on the long threaded rod 8 and located inside the control mounting plate 3, is the core of realizing the action conversion. Its conical surface slides against the spherical end of the push rod 14 to form a sliding pair. When the first nut 16 located on the outer side of the control mounting plate 3 is tightened, the long threaded rod 8 moves axially backward. This movement produces two synchronous actions: First, the second nut 18 at the front end of the long threaded rod 8 moves backward. Since the card 4 is made of aluminum alloy with moderate elasticity and bending properties, the second nut 18 will push the card 4 to bend backward, so that the front end of the card 4 and the control plate 3 apply pressure together, forming an initial bending clamping force on the shelf angle steel leg 2 embedded in the gap. This clamping achieved by the plastic bending of the card 4 solves the problems of irreversibility of traditional welding connection and easy loosening of single bolt, and provides a new fixing method. The aluminum alloy card 4 has a certain rigidity and deformability, which can ensure stable clamping while solving the problem of difficult installation with certain tolerances.

[0022] In addition, such as Figure 3 and Figure 4 As shown, to achieve a more stable fixation, this utility model incorporates further fixing and anti-retraction designs. A one-way toothed groove group 15 is provided at the front end of the clamping column 7. Correspondingly, an extension piece 10 is fixedly provided on one side of the connecting piece 17. The end of the extension piece 10 is connected to a one-way locking tooth 12 via a spring telescopic rod 13. When the first nut 16 is tightened, causing the long threaded rod 8 to move backward, the conical push wheel 11 moves backward synchronously with the long threaded rod 8. Because the diameter of the contact point between its conical surface and the end of the push rod 14 increases, it pushes the push rod 14 and the clamping column 7 fixedly connected to it to move in the square insertion hole 9 in a specified direction. At this time, the one-way locking tooth... Under the elastic action of the spring telescopic rod 13, the tooth 12 engages and locks with the one-way tooth groove group 15 on the clamping column 7. This one-way engagement design forcibly restricts the clamping column 7 to move only in one direction, preventing retraction. The outwardly extending clamping column 7 firmly presses against or inserts into the side of the shelf angle steel leg 2, forming a second layer of rigid fixing force after the card 4 bends and clamps. This double clamping combined with the one-way anti-retraction design solves the problem of possible loosening and failure of single bolt fixing or welding, improves the rigidity and long-term stability of the connection node between the beam and the upright, i.e. the shelf angle steel leg 2, thereby improving the safety and load-bearing life of the entire warehouse rack.

[0023] It should be added that, such as Figure 5As shown, when installing the hanging plate of the warehouse rack beam 1, the operator first fixes the hanging plate connecting plate 5 to the corner of the rack beam 1 with fastening bolts. Then, the rack angle steel leg 2 is placed into the gap formed between the card 4 and the control hanging plate 3. Next, the long threaded rod 8 is conveniently placed through the L-shaped insertion slot 6, so that its front end passes through the pre-drilled hole of the control hanging plate 3, the corresponding hole on the rack angle steel leg 2, and the hole on the card 4 in sequence, and the second nut 18 is screwed on for initial positioning but not fully tightened. The part of its rear end that extends after passing through the control hanging plate 3 is screwed on the first nut 16. The key operation of this technology is that when tightening the first nut 16 on the outside of the control hanging plate 3, when the long threaded rod 8 is subjected to tightening force and moves backward as a whole, on the one hand, the second nut 18 at its front end pushes the aluminum alloy card. 4. The card 4 is plastically bent backward, so that the control plate 3 works together to clamp the main body of the shelf angle steel leg 2. On the other hand, the tapered push wheel 11 on the long threaded rod 8 moves backward, and its increased tapered radius pushes the ball end of the push rod 14 on the inner side of the clamping column 7, forcing the clamping column 7 to overcome possible initial resistance and push outward. The one-way toothed groove group 15 at the front end of the clamping column 7 engages with the one-way tooth 12 of the spring telescopic rod 13 on the extension plate 10 of the connecting piece 17, preventing the clamping column 7 from retreating under pressure or vibration. Finally, the clamping column 7, which extends outward and is stable, presses against or embeds into the side wall of the shelf angle steel leg 2. The L-shaped insertion slot 6 design simplifies the disassembly and assembly of the long threaded rod 8. This technology can achieve multiple fixations with only one tightening operation, solving the problems of weld cracking and bolt loosening pointed out in the background technology.

[0024] The working principle of this embodiment is as follows: This technology includes a hanging plate connecting plate 5 connected to the corner of the shelf beam 1 and fixed by fastening bolts. The shelf beam 1 designed in this technology is used to support the storage of goods. Cards 4 and control hanging plates 3 are fixed to the front and rear ends of the other side of the hanging plate connecting plate 5. An insertion groove 6 is opened between the upper ends of the card 4 and the control hanging plate 3 near the hanging plate connecting plate 5. A long threaded rod 8 is set inside the insertion groove 6. The L-shaped insertion groove 6 facilitates the removal and disassembly of the long threaded rod 8. A tapered push wheel 11 is fixedly sleeved on the long threaded rod 8 located inside the control hanging plate 3 to hold the shelf angle steel leg 2. One side is inserted into the gap between the card 4 and the control plate 3. At the same time, the front end of the long threaded rod 8 passes through the shelf angle steel leg 2. The front end of the long threaded rod 8 is attached to the front side of the card 4 with the second nut 18. The rear end is tightened with the first nut 16. Since the tightening operation is performed from the rear end, the long threaded rod 8 will move backward, which will drive the second nut 18 at the front end to push the card 4 backward. Since the card 4 is made of aluminum alloy, it has a certain degree of toughness and can be bent slightly. Therefore, the card 4 will bend backward to cooperate with the front end of the control plate 3 to squeeze and fix the shelf angle steel leg 2, so as to achieve the effect of fixing. During the aforementioned fixed operation, the control plate 3 of this technology is internally equipped with a connecting piece 17. A square insertion hole 9 is provided inside the connecting piece 17. A clamping post 7 is movably installed inside the square insertion hole 9. A one-way toothed groove assembly 15 is provided at the front end of the clamping post 7. A push rod 14 is fixed to the inner side of the clamping post 7. One end of the push rod 14 has a spherical design and contacts the tapered push wheel 11 of the long threaded rod 8. An extension piece 10 is fixed to one side of the connecting piece 17 near the one-way toothed groove assembly 15. A spring telescopic rod 1 is fixed to the rear end of the extension piece 10. 3. The rear end of the spring telescopic rod 13 is fixed with a one-way locking tooth 12, which works in conjunction with the one-way tooth groove group 15. When the long threaded rod 8 moves backward, the contact surface between the conical push wheel 11 and the push rod 14 will become wider and wider, thereby pushing the clamping column 7 to move outward. It also engages with the one-way tooth groove group 15 and the one-way locking tooth 12 to prevent retraction. It can only move outward in one direction, so that one end of the clamping column 7 contacts the shelf angle steel leg 2 to achieve top pressure fixation, or is inserted into the shelf angle steel leg 2, thereby achieving a double fixation effect.

[0025] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
