Description

Technical Field

[0001] This invention relates to the field of logistics and warehousing equipment technology, and in particular to a prefabricated hardware structure for heavy-duty logistics racks. Background Technology

[0002] Heavy-duty shelving is a core steel structure in warehousing and logistics systems used to support large-tonnage, large-sized goods. It is widely used in manufacturing warehouses, logistics distribution centers, and large supermarket warehouses. Traditional heavy-duty shelving is mostly made of columns, beams, and diagonal braces connected by bolts or clips. The connection nodes between components often lack rigidity. Under long-term heavy loads or accidental impacts from forklifts or other handling equipment, nodes are prone to loosening, beams to fall off, or even the whole structure to collapse. To improve safety, some shelving units are equipped with fixed guardrails or chains on the front of the shelves. However, the guardrails cannot be automatically flipped, causing interference when picking up and placing goods. In addition, the bottom support structure of the shelving is mostly fixed in spacing, which makes it difficult to adapt to the stable bearing of goods of different widths and has poor adjustment flexibility.

[0003] Patent document CN114056819A discloses a crash barrier structure for heavy-duty shelving. The structure has a buffer plate installed on the outside of the uprights by springs and a flip-up stop bar set on the edge of the shelf to mitigate impact and prevent goods from slipping.

[0004] While the aforementioned devices, including the anti-collision buffer plate and the flip-up stop bar, can improve safety to some extent, the stop bar requires manual flipping, resulting in low operational efficiency. Furthermore, the bottom support structure remains fixed, preventing flexible adjustment of the support bar spacing to accommodate goods of different sizes. Overall, the assemblability and adaptability need improvement. Therefore, we propose an assemblable hardware structure for heavy-duty logistics racks to address this issue. Summary of the Invention

[0005] The purpose of this invention is to provide an assembled hardware structure for heavy-duty logistics racks to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A prefabricated hardware structure for heavy-duty logistics racks, comprising: The logistics rack has multiple layer rods fixed on both sides, and reinforcing ribs are welded between the multiple layer rods. Anti-collision railings are provided on both sides of the logistics rack. A shelf assembly includes a slot fixed to the surface of a logistics rack, a shelf is fitted inside the logistics rack, insert rods are fixed around the shelf, and a first bolt is inserted between the slot and the insert rod. A support rod is attached to the surface of the logistics rack, a second bolt is installed between the support rod and the logistics rack, a support rod is connected to one side of the support rod, and a third bolt is installed between the support rod and the support rod. A pad is fixed to the upper end of the support rod. A protective frame assembly includes a connector fixed to the surface of a logistics rack, and a C-shaped plate is fixed to the surface of the connector. A rotating rod is rotatably connected to the inner cavity of the C-shaped plate, and a flipping frame is fixed to the surface of the rotating rod. A motor is fixed to one side of the C-shaped plate. The base frame assembly includes a groove that fits onto the surface of the logistics rack. A slide rail is fixed to the upper end face of the groove, and multiple threaded holes are equidistantly opened on the surface of the slide rail. A sliding sleeve is slidably fitted onto the surface of the slide rail, and a fourth bolt is fitted inside the sliding sleeve. A locking rod seat is fixed to the upper end face of the sliding sleeve, and a support rod is fitted between two locking rod seats.

[0007] Preferably, the insert rod and the slot form an assemblable structure through the first bolt, and the shelf forms a detachable structure through the insert rod and the slot.

[0008] Preferably, the support rod is connected to the logistics rack via a second bolt to form a detachable structure, and the pad is movably connected to the lower end face of the shelf.

[0009] Preferably, the motor output end is connected to the rotating rod through the C-shaped plate, and the tilting frame forms a rotatable structure with the rotating rod and the motor.

[0010] Preferably, the flip-over bracket is mounted on the front end of the shelf to cover the goods on the shelf surface.

[0011] Preferably, the fourth bolt is threadedly connected to the threaded hole, and the sliding sleeve forms a fixable structure with the slide rail through the fourth bolt.

[0012] Preferably, the support rod forms a slidable structure between the sliding sleeve and the slide rail, which is used to adjust the distance between the two support rods.

[0013] Preferably, the crash barrier is fixedly connected to the logistics rack by an elastic buffer, and the outer surface of the crash barrier is covered with a rubber layer.

[0014] Preferably, the reinforcing ribs are welded in an X-shape between two adjacent layer rods, and the thickness of the reinforcing ribs is greater than the thickness of the layer rods.

[0015] Preferably, the motor is a servo motor, and the motor is electrically connected to a controller, which is used to control the rotation angle of the tilting frame.

[0016] The beneficial effects of this invention are as follows: 1. In this invention, the device achieves efficient assembly, flexible adjustment and safe protection of heavy logistics racks through the quick disassembly and assembly structure of the shelf assembly, the electric flip protection of the guard frame assembly, the sliding adjustable support rod of the base frame assembly and the reinforced protection of the reinforcing ribs and anti-collision rails.

[0017] 2. In this invention, the base frame assembly is fixed to the bottom support legs of the logistics rack by a tight fit through a sleeve groove. A sliding sleeve is slidably connected to the slide rail. A self-lubricating copper sleeve is embedded in the inner wall of the sliding sleeve. The fourth bolt is a wing bolt for easy manual tightening. The support rod is connected to the sliding sleeve through a clamp seat. The distance between the two support rods can be flexibly adjusted. It can quickly adapt to the bottom support requirements of goods of different widths without tools. The anti-collision guard absorbs impact energy through elastic buffer and rubber layer, further enhancing the overall adaptability and impact resistance of the device. 3. In this invention, the shelf assembly adopts a quick assembly structure with a plug and slot and a first bolt. The end of the plug is chamfered for easy insertion. When disassembling, the shelf can be lifted by simply unscrewing the first bolt without moving other parts. At the same time, the support rod and the support rod form a detachable vertical support through the second bolt and the third bolt. The pad is movably connected to the lower end face of the shelf and a rubber pad is attached, which not only buffers the impact force but also allows for thermal expansion and contraction displacement, realizing the quick replacement and maintenance of the shelf and greatly improving the assembly efficiency. 4. In this invention, the protective frame assembly uses a servo motor to drive the tilting frame to rotate. The motor is electrically connected to the controller and has a built-in encoder, which can precisely control the rotation angle within the range of 0 to 120 degrees. When the tilting frame is unfolded to 90 degrees, it effectively shields the goods at the front of the shelf, preventing them from tilting forward and falling. The controller is equipped with a remote control receiver module, supporting remote operation with a handheld remote control. In an emergency, the power can be cut off to maintain the current angle. The surface of the tilting frame is painted with yellow and black warning stripes, and nylon mesh can be installed inside, significantly improving the active safety protection capability of the goods. 5. In this invention, the device uses X-shaped cross-welded reinforcing ribs, and the thickness of the reinforcing ribs is greater than the thickness of the shelf rods. Combined with the added circular reinforcing plates, the bending stiffness and overall load-bearing capacity of the shelf rods are significantly improved. Tests have shown that the load-bearing capacity of two adjacent shelf rods is increased by more than 30%. After welding, the grinding and anti-rust treatment avoids stress concentration and corrosion, effectively extending the service life of the logistics rack. It can stably support heavy goods and meet the needs of high-intensity warehousing operations. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1 - Figure 6 A prefabricated hardware structure for heavy-duty logistics racks, comprising: Logistics rack 1, multiple layer rods 2 are fixed on both sides of logistics rack 1, and reinforcing ribs 3 are welded between the multiple layer rods 2. Anti-collision railings 4 are set on both sides of logistics rack 1. In actual installation, the logistics rack 1 is made of high-strength steel. The layer bars 2 are evenly arranged on both sides of the logistics rack 1 by welding. The welding position of the reinforcing ribs 3 is located at the middle intersection of the layer bars 2, which can significantly improve the bending strength of the layer bars 2. The anti-collision rails 4 and the elastic buffers on both sides of the logistics rack 1 can be made of polyurethane springs with a rubber layer thickness of 5 mm, which are used to absorb the accidental impact energy of forklifts and other handling equipment.

[0022] Shelf assembly 5 includes a slot 501 fixed to the surface of logistics rack 1, a shelf 502 sleeved inside the logistics rack 1, insert rods 503 fixed around the shelf 502, and a first bolt 504 inserted between the slot 501 and the insert rods 503, a support rod 505 attached to the surface of logistics rack 1, a second bolt 506 installed between the support rod 505 and logistics rack 1, a support rod 507 connected to one side of the support rod 505, and a third bolt 509 installed between the support rod 507 and the support rod 505, and a pad 508 fixed to the upper end of the support rod 507; In the specific assembly process of shelf assembly 5, the slot 501 is first pre-fixed to the predetermined position on the inner wall of the logistics rack 1 by welding or bolting. The shelf 502 is made of rectangular steel pipe welded together. The diameter of the insert rod 503 around it forms a clearance fit with the inner diameter of the slot 501. The first bolt 504 is an M8 hexagonal socket head cap screw, which passes through the through hole on the side of the slot 501 to lock the insert rod 503, so as to achieve quick fixation. The support rod 505 fits against the outer column of the logistics rack 1. The second bolt 506 is an M10 bolt, which fastens the support rod 505 to the logistics rack 1. The support rod 507 and the support rod 505 are vertically connected by the third bolt 509. The pad plate 508 is a galvanized steel plate with a thickness of 4 mm, which is welded to the upper end face of the support rod 507 to support the bottom edge of the shelf 502 and prevent the shelf 502 from sinking and deforming.

[0023] The protective frame assembly 6 includes a connector 601 fixed to the surface of the logistics rack 1, and a C-shaped plate 602 fixed to the surface of the connector 601. A rotating rod 603 is rotatably connected to the inner cavity of the C-shaped plate 602, and a tilting frame 604 is fixed to the surface of the rotating rod 603. A motor 605 is fixed to one side of the C-shaped plate 602. In the protective frame assembly 6, the connector 601 is fixed to the front column of the logistics rack 1 by welding or high-strength bolts. The connector 601 is made of L-shaped angle steel. The opening of the C-shaped plate 602 faces the shelf 502. The two ends of the rotating rod 603 are installed in the upper and lower flanges of the C-shaped plate 602 by rolling bearings. The motor 605 is a DC 24-volt geared motor. The housing of the motor 605 is fixed to the outside of the C-shaped plate 602 by screws. The output shaft of the motor 605 is connected to one end of the rotating rod 603 by a flat key. When the motor 605 is powered on and rotates, the rotating rod 603 drives the tilting frame 604 to rotate around the axis. The tilting frame 604 is a rectangular steel tube frame, and its length is equal to the width of the shelf 502.

[0024] The base frame assembly 7 includes a groove 701 that fits onto the surface of the logistics rack 1. A slide rail 702 is fixed to the upper end face of the groove 701, and a plurality of threaded holes 703 are equidistantly opened on the surface of the slide rail 702. A sliding sleeve 704 is slidably fitted onto the surface of the slide rail 702. A fourth bolt 705 is fitted inside the sliding sleeve 704. A locking rod seat 706 is fixed to the upper end face of the sliding sleeve 704, and a support rod 707 is fitted between the two locking rod seats 706. The slot 701 of the base frame assembly 7 is a U-shaped channel steel, and its opening size is tightly fitted with the outer diameter of the bottom support leg of the logistics rack 1. The slot 701 is further secured by locking screws on both sides. The slide rail 702 is made of I-beam steel rail and is fixed to the upper end face of the slot 701 by welding. A threaded hole 703 is machined every 100 mm on the surface of the slide rail 702. The thread specification is M12. The slide sleeve 704 is a square slider with a nylon wear-resistant pad on the inner wall. The slide sleeve 704 slides along the length of the slide rail 702. The fourth bolt 705 passes through the through hole at the top of the slide sleeve 704 and is screwed into the threaded hole 703 to fix the slide sleeve 704 in the required position. The clamping rod seat 706 consists of two upright plates. Each upright plate has a semi-circular groove. The two ends of the support rod 707 are inserted into the groove and locked with spring retainers. The distance between the two support rods 707 is adjusted by sliding the slide sleeve 704 to adapt to the support requirements of the bottom of goods of different widths.

[0025] In this embodiment, the insertion rod 503 forms an assemblable structure with the slot 501 via the first bolt 504, and the shelf 502 forms a detachable structure with the insertion rod 503 and the slot 501. In practical applications, the end of the insertion rod 503 can be chamfered to facilitate insertion into the slot 501. The first bolt 504 uses an anti-loosening washer to prevent the bolt from loosening when the logistics rack vibrates. When disassembling the shelf 502, only the first bolt 504 needs to be unscrewed to lift the shelf 502 upwards without moving other parts, which is conducive to quickly replacing shelves of different specifications.

[0026] In this embodiment, the support rod 505 is connected to the logistics rack 1 by the second bolt 506 to form a detachable structure. The pad 508 is movably connected to the lower end face of the shelf 502. The second bolt 506 is symmetrically arranged at the upper and lower ends of the support rod 505, with two bolts at each end, to ensure that the support rod 505 is tightly attached to the column of the logistics rack 1. A rubber pad can be attached to the upper surface of the pad 508 to buffer the impact force when the shelf 502 is placed, and at the same time increase the friction to prevent the shelf 502 from slipping. The movable connection method allows the shelf 502 to have a small displacement when it expands and contracts with heat, avoiding structural stress concentration.

[0027] In this embodiment, the output end of the motor 605 is connected to the rotating rod 603 via the C-shaped plate 602. The tilting frame 604 forms a rotatable structure with the motor 605 through the rotating rod 603. An electromagnetic clutch can be installed at the connection between the motor 605 and the rotating rod 603. When the motor 605 is de-energized, the clutch disengages, and the tilting frame 604 can be manually rotated. The motor 605 is covered with a protective metal mesh to prevent debris from being rolled in. The rotation angle range of the tilting frame 604 is set from 0 degrees to 120 degrees, where 0 degrees corresponds to the tilting frame 604 being vertically retracted and 90 degrees corresponds to horizontally unfolded, which is used to prevent the goods from tilting forward.

[0028] In this embodiment, the tilting frame 604 is located on the front end of the shelf 502 to cover the goods on the surface of the shelf 502. When the tilting frame 604 is in the unfolded state, the vertical distance between its lower edge and the upper surface of the shelf 502 is 50 mm, ensuring that the forklift forks can be smoothly inserted into the bottom of the goods. Nylon mesh or wire mesh can be installed inside the frame of the tilting frame 604 to prevent small goods from falling through the gaps. The surface of the tilting frame 604 is sprayed with yellow and black warning stripes to remind operators to pay attention to safety.

[0029] In this embodiment, the fourth bolt 705 is threadedly connected to the threaded hole 703. The sliding sleeve 704 forms a fixed structure with the slide rail 702 through the fourth bolt 705. The fourth bolt 705 is a wing bolt or a bolt with a handle, which makes it easy for the operator to manually tighten or loosen it without using tools. Two fourth bolts 705 are provided on each sliding sleeve 704, located on both sides of the slide rail 702 respectively, to balance the locking force. The edge of the threaded hole 703 on the slide rail 702 is chamfered to facilitate the alignment and screwing of the fourth bolt 705.

[0030] In this embodiment, the support rod 707 forms a slidable structure with the slide sleeve 704 and the slide rail 702, which is used to adjust the distance between the two support rods 707. The inner wall of the slide sleeve 704 is embedded with a self-lubricating copper sleeve to ensure smooth sliding and wear resistance. The support rod 707 is made of circular hollow steel tube with rubber anti-slip caps at both ends to increase the contact stability with the bottom of the goods. When adjusting the distance, first loosen the fourth bolt 705, push the slide sleeve 704 along the slide rail 702 to the target distance, and then tighten the fourth bolt 705 again. The distance adjustment range of the two support rods 707 is between 200 mm and 1500 mm.

[0031] In this embodiment, the crash barrier 4 and the logistics rack 1 are fixedly connected by elastic buffers, and the outer surface of the crash barrier 4 is covered with a rubber layer. The elastic buffer is a cylindrical rubber spring or a hydraulic buffer, and three buffers are evenly arranged between each crash barrier 4 and the logistics rack 1. The rubber layer is made of natural rubber material, with a thickness of 8 mm, and the surface is provided with anti-slip raised textures. When the crash barrier 4 is impacted, the buffer can compress and deform to absorb the impact energy, while the rubber layer protects the crash barrier 4 from scratches.

[0032] In this embodiment, the reinforcing ribs 3 are welded in an X-shape between two adjacent layer rods 2, and the thickness of the reinforcing ribs 3 is greater than the thickness of the layer rods 2. The thickness of the reinforcing ribs 3 is 2 mm thicker than that of the layer rods 2. For example, when the thickness of the layer rods 2 is 4 mm, the thickness of the reinforcing ribs 3 is 6 mm. A circular reinforcing plate can be added at the center point of the X-shape intersection to further improve the torsional stiffness. After welding, all welds are ground and rust-proofed to prevent stress concentration and corrosion. This structure increases the overall load-bearing capacity of adjacent layer rods 2 by more than 30%.

[0033] In this embodiment, motor 605 is a servo motor, and motor 605 is electrically connected to a controller. The controller is used to control the rotation angle of the tilting frame 604. The servo motor has a built-in encoder, which can accurately feed back the rotation angle position of the rotating rod 603. The controller adopts a programmable logic controller (PLC) or a microcontroller, which can set the rotation speed, acceleration and positioning angle of the tilting frame 604. The controller is also connected to a remote control receiver module, and the operator can remotely control the opening and closing of the tilting frame 604 through a handheld remote control. In an emergency, the controller can cut off the power to motor 605 and maintain the current angle to prevent the goods from falling accidentally.

[0034] In this embodiment, the working principle of the prefabricated hardware structure for heavy-duty logistics racks is as follows: Firstly, the logistics rack 1 serves as the main support frame, with multiple layer rods 2 evenly welded on both sides. The layer rods 2 are reinforced with X-shaped cross-welded reinforcing ribs 3 to enhance bending strength, enabling the logistics rack 1 to withstand the vertical load of heavy goods. The thickness of the reinforcing ribs 3 is greater than that of the layer rods 2, and a circular reinforcing plate is added in the center to effectively resist torsional deformation, increasing the overall load-bearing capacity by more than 30%. Assembly and load-bearing principle of shelf assembly 5: The slot 501 is pre-fixed on the inner wall of the logistics rack 1. The insert rods 503 around the shelf 502 are inserted into the slot 501. The ends of the insert rods 503 are chamfered for easy alignment. The insert rods 503 are then locked through the through holes on the side of the slot 501 by the first bolt 504, forming a detachable assembly structure. At the same time, the support rod 505 is attached to the outer column of the logistics rack 1 by the second bolt 506. The support rod 507 and the support rod 505 are vertically connected by the third bolt 509. The pad 508 on the upper end of the support rod 507 supports the bottom edge of the shelf 502. The pad 508 is attached to the pad 508, which can not only buffer the impact force when the shelf 502 is placed, but also increase the friction to prevent slippage. The movable connection method allows the shelf 502 to move slightly when it expands and contracts with heat, avoiding stress concentration. When the shelf 502 needs to be replaced, only the first bolt 504 needs to be unscrewed to lift the shelf 502 upwards without moving other parts. Working principle of the protective frame assembly 6: The connector 601 is fixed to the front column of the logistics rack 1. The opening of the C-shaped plate 602 faces the shelf 502. The rotating rod 603 is installed in the C-shaped plate 602 through rolling bearings. The tilting frame 604 is fixed on the rotating rod 603. The motor 605 is a servo motor, and its output shaft is connected to the rotating rod 603 through a flat key. The controller precisely controls the rotation angle of the motor 605 through a built-in encoder, driving the rotating rod 603 to rotate the tilting frame 604 within the range of 0 degrees to 120 degrees. At 0 degrees, the tilting frame 604 is vertical. The lower storage unit unfolds horizontally at 90 degrees, with the front end of the cover shelf 502 preventing goods from tipping forward and falling. An electromagnetic clutch can be installed at the connection between the motor 605 and the rotating rod 603. When the power is off, the clutch disengages, allowing manual rotation of the tilting frame 604. The surface of the tilting frame 604 is painted with yellow and black warning stripes. Nylon mesh or wire mesh can be installed inside the frame to prevent small goods from falling. The controller is also connected to a remote control receiver module, allowing operators to remotely control the opening and closing of the tilting frame 604 via a handheld remote control. In an emergency, the controller can cut off the power and maintain the current angle. Adjustment principle of base frame assembly 7: The sleeve groove 701 is a U-shaped channel steel, which is tightly fitted to the bottom support leg of the logistics rack 1 and fastened with locking screws. The slide rail 702 is fixed on the upper end face of the sleeve groove 701. The surface of the slide rail 702 is machined with threaded holes 703 every 100 mm. The inner wall of the slide sleeve 704 is embedded with a self-lubricating copper sleeve, which slides along the length of the slide rail 702. The fourth bolt 705 at the top is a wing bolt, which passes through the through hole of the slide sleeve 704 and is screwed into the threaded hole 703 to fix the slide sleeve 704. The support rod 707 is sleeved between the locking rod seat 706 at the upper end of the two slide sleeves 704. The support rod 707 has rubber anti-slip caps at both ends. When in use, the fourth bolt 705 is loosened and the slide sleeve 704 is pushed to move to adjust the distance between the two support rods 707. The distance range is 200 mm to 1500 mm. Then the fourth bolt 705 is tightened so that the support rod 707 stably supports the bottom of the goods and adapts to goods of different widths. The crash barriers 4 are fixed to both sides of the logistics rack 1 by elastic buffers such as cylindrical rubber springs or hydraulic buffers. Each crash barrier 4 has 3 buffers evenly arranged, and the outer surface is covered with an 8 mm thick natural rubber layer with anti-slip raised texture. When a forklift or other handling equipment accidentally hits the rack, the buffers are compressed and deformed to absorb the impact energy, and the rubber layer protects the crash barrier 4 from being scratched, thereby protecting the logistics rack 1 and the goods. In summary, this device achieves efficient assembly, flexible adjustment and safe protection of heavy-duty logistics racks through the quick disassembly and assembly structure of the shelf assembly 5, the electric flip protection of the guardrail assembly 6, the sliding adjustable support rod 707 of the base frame assembly 7 and the reinforced protection of the reinforcing ribs 3 and crash barriers 4.
