Description

Technical Field

[0001] This utility model relates to the field of cargo storage technology, and more specifically, to a heavy-duty pallet racking device with a self-locking connection. Background Technology

[0002] Pallet racking systems are a type of racking equipment used in warehousing. They are characterized by high load-bearing capacity and high safety, and are widely used in manufacturing, third-party logistics, and other fields. They have a wide range of height adaptability and can be customized according to the height of the warehouse, effectively utilizing the vertical space of the warehouse.

[0003] When forklifts retrieve goods from pallet-mounted heavy-duty racking systems, the forklifts may come into contact with the racking. Improper operation can cause the racking to tilt to one side, and if the tilt angle is too large, the racking may fall over, creating a chain reaction. Adding auxiliary support devices at the bottom to counteract the tilt would increase the floor space required, affecting both goods storage and forklift operation. Therefore, we propose a self-locking connection for heavy-duty pallet-mounted racking systems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a self-locking heavy-duty pallet racking device to solve the technical problem that it is not easy to handle the tilting state caused by the collision of the current heavy-duty racking when the forklift picks up the goods.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a self-locking heavy-duty pallet racking device, including two adjacent racks, and an active adjustment structure and a passive support structure respectively installed on opposite sides of the two racks. Both the active adjustment structure and the passive support structure are provided with positioning plates for connecting the racks. The positioning plate on the active adjustment structure is connected to a hook plate. The positioning plate on the passive support structure is connected to two side connecting plates and a spring rod. The side connecting plates are provided with a spring return assembly. The side of the spring return assembly away from the side connecting plates is provided with a locking plate that cooperates with the hook plate. The spring rod is provided with a compression spring and a support rod is connected based on the compression spring. The bottom of the locking plate is provided with an extension plate. The side connecting plates are provided with an inclined plate. The inclined plate is provided with a positioning block. The positioning block is provided with a limiting plate.

[0006] Preferably, both the active adjustment structure and the passive support structure are provided with semi-circular protrusions. The protrusion on the active adjustment structure is connected to the hook plate based on a ratchet. The protrusion on the passive support structure is fixed relative to the side connecting plate. The side of the hook plate away from the positioning plate is set in an upward bulging state. The card plate is provided with a recessed structure that matches the bulging state.

[0007] Preferably, the positioning rod on the spring reset assembly is inserted and fixed to the side connecting plate, a crossbar is provided between the two clamping plates, the bottom of the crossbar is connected to the extension plate, and the side of the extension plate away from the crossbar corresponds to the limiting plate.

[0008] Preferably, a limiting ring is provided on the outside of the spring rod of the compression spring, and the compression spring is connected to the support rod based on the limiting ring. The rod between the support rod and the limiting ring passes through an annular slot hole opened on the inclined plate.

[0009] Preferably, the limiting plate is configured as a right-angled plate structure, and a bearing is provided between it and the positioning block. The side of the limiting plate away from the positioning block is in contact with the limiting ring, and the compression spring at the rear end of the limiting plate is in a compressed state when it is in contact with the limiting ring.

[0010] Preferably, the support rod has a vertical buffer pad on the side away from the spring rod that is horizontal to the shelf, and the rod connecting the support rod and the limiting ring moves back and forth based on the annular groove on the inclined plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model involves setting an active adjustment structure and a passive support structure on the frame between two adjacent shelves. These structures are interconnected in a horizontal state based on hook plates and clamping plates. Simultaneously, the spring return assembly is in a stretched state when the clamping plates are connected. When the shelf where the active adjustment structure is located tilts, the hook plate tilts, disconnecting from the clamping plate. The clamping plate quickly retracts based on the spring return assembly, and the extension plate at its bottom springs back to adjust the angle of the limiting plate, removing the restriction between it and the spring rod. This causes the compression spring under pressure to pop out, driving the support rod to pop out and support and buffer the tilted shelf, achieving the purpose of supporting the tilted shelf and reducing the possibility of a chain reaction caused by continuous tilting under forklift impact. Furthermore, this device, installed on the shelf, will not affect the goods storage area or the forklift operating area. The installation positions of the active adjustment structure and the passive support structure, as well as the connection angle between the hook plate and the clamping plate, can be adjusted according to the distance between the two shelves, making it highly adaptable. It solves the technical problem of the difficulty in handling the tilting state caused by forklift collisions when heavy-duty shelves are being retrieved.

[0012] 2. This utility model also uses an extension plate, which works in conjunction with a limiting plate to restrict the position of the limiting ring. When the extension plate retracts, it impacts the upper position of the limiting plate. Based on the rotation of the positioning block, the side of the limiting plate connected to the limiting ring moves downward, thereby making the limiting ring make contact. The compression spring connected to the limiting ring releases pressure, causing the support rod to pop out quickly, supporting the tilted shelf and reducing the tilting speed.

Detailed Implementation

[0015] like Figures 1 to 4 As shown, this utility model relates to a self-locking heavy-duty pallet racking device, including two adjacent racks, and an active adjustment structure 100 and a passive support structure 200 respectively installed on opposite sides of the two racks. Both the active adjustment structure 100 and the passive support structure 200 are provided with positioning plates 110 for connecting the racks. The positioning plate 110 on the active adjustment structure 100 is connected to a hook plate 120, and the positioning plate 110 on the passive support structure 200 is connected to two side connecting plates 210 and... A spring rod 260 is provided, and a spring return assembly 220 is provided on the side connecting plate 210. The side of the spring return assembly 220 away from the side connecting plate 210 is provided with a locking plate 230 that cooperates with the hook plate 120. A compression spring 261 is provided on the spring rod 260 and a support rod 250 is connected based on the compression spring 261. An extension plate 231 is provided at the bottom of the locking plate 230. An inclined plate 240 is provided on the side connecting plate 210. A positioning block 241 is provided on the inclined plate 240. A limiting plate 242 is provided on the positioning block 241.

[0016] This invention features an active adjustment structure 100 and a passive support structure 200 installed on the frame between two adjacent shelves. These structures are interconnected in a horizontal state based on a hook plate 120 and a locking plate 230. Simultaneously, the spring return assembly 220 is in a stretched state when the locking plate 230 is connected. When the shelf containing the active adjustment structure 100 is tilted, the hook plate 120 tilts, disconnecting from the locking plate 230. The locking plate 230 then quickly retracts based on the spring return assembly 220, and its bottom extension plate 231 springs back to adjust the angle of the limiting plate 242, removing the restriction between it and the spring rod 260, thus allowing the pressure-bearing structure to adjust. When the compression spring 261 is in a certain state, it pops out, driving the support rod 250 to pop out and support and buffer the tilted shelf, thus achieving the purpose of supporting the shelf when it is tilted and reducing the possibility of a chain reaction caused by continuous tilting under forklift impact. At the same time, this device is installed on the shelf and will not affect the goods storage area or the forklift running area. The installation position of the active adjustment structure 100 and the passive support structure 200 and the connection angle between the hook plate 120 and the clamping plate 230 can be adjusted according to the distance between the two shelves. It has high applicability and solves the technical problem of the difficulty in handling the tilting state caused by the collision of heavy-duty shelves with forklifts when picking up goods.

[0017] Specifically, both the active adjustment structure 100 and the passive support structure 200 are provided with semi-circular protrusions. The protrusion on the active adjustment structure 100 is connected to the hook plate 120 based on a ratchet. The protrusion on the passive support structure 200 is fixed relative to the side connecting plate 210. The side of the hook plate 120 away from the positioning plate 110 is set in an upward bulging state. The clamping plate 230 is provided with a recessed structure that matches this bulging state. By setting the active adjustment structure 100 and the passive support structure 200 at corresponding positions on the two shelves, after installation, they are mutually restricted by the recess and bulge between the clamping plate 230 and the hook plate 120. At this time, the spring on the spring reset assembly 220 is in a stretched state, which facilitates the angle adjustment of the hook plate 120 when tilted, thereby realizing the separation operation after angle adjustment.

[0018] Furthermore, the positioning rod on the spring reset assembly 220 is inserted and fixed to the side connecting plate 210. A crossbar is provided between the two clamping plates 230. The bottom of the crossbar is connected to the extension plate 231. The side of the extension plate 231 away from the crossbar corresponds to the limiting plate 242. The movement of the clamping plate 230 drives the movement of the crossbar, thereby driving the movement of the extension plate 231 at the bottom of the crossbar. The extension plate 231 moves backward and contacts the limiting plate 242, so that the position of the limiting plate 242 can be adjusted, which facilitates subsequent operations.

[0019] It is worth noting that a limiting ring 262 is provided on the outside of the spring rod 260 on the compression spring 261, and the compression spring 261 is connected to the support rod 250 based on the limiting ring 262. The rod between the support rod 250 and the limiting ring 262 passes through the annular slot on the inclined plate 240. One end of the spring rod 260 is installed on the positioning plate 110 and connected to the compression spring 261 externally. At the same time, the end of the compression spring 261 is connected to the limiting ring 262 and connected to the support rod 250 above. This allows the support rod 250 to extend when the compression spring 261 extends. The relative position and angle are limited by the annular slot on the inclined plate 240, which facilitates a quick response and buffering of the tilted shelf and reduces the tilting speed.

[0020] It is worth mentioning that the limiting plate 242 is set in a right-angle plate structure, and a bearing is provided between it and the positioning block 241. The side of the limiting plate 242 away from the positioning block 241 is in contact with the limiting ring 262, and the compression spring 261 at the rear end of the limiting plate 242 is in a compressed state when it is in contact with the limiting ring 262. By having the limiting plate 242 in contact with the limiting ring 262 in the non-tilted state, it is ensured that the limiting plate 242 can be tilted by impact based on the extension plate 231, thereby releasing the compression spring 261 to extend the support rod 250, realizing a rapid tilting response and improving processing efficiency.

[0021] This utility model also uses an extension plate 231, which cooperates with a limiting plate 242 to restrict the position of the limiting ring 262. When the extension plate 231 retracts, it impacts the upper position of the limiting plate 242. Based on the rotation of the positioning block 241, the side of the limiting plate 242 connected to the limiting ring 262 moves downward, thereby making the limiting ring 262 make contact. The compression spring 261 connected to the limiting ring 262 releases pressure, causing the support rod 250 to pop out quickly, supporting the tilted shelf and reducing the tilting speed.

[0022] It is worth noting that the support rod 250 has a vertical buffer pad that is horizontal to the shelf on the side away from the spring rod 260. The rod connecting the support rod 250 and the limiting ring 262 moves back and forth based on the annular groove on the inclined plate 240. The diameter of the support rod 250 is larger than the diameter of the annular groove on the inclined plate 240, which ensures the maximum tilt angle limit of the inclined shelf. At the same time, the spring rod 260 realizes the rapid pop-out operation of the support rod 250 based on the compression spring 261, which improves the support performance.

[0023] Working Principle: This embodiment provides a self-locking heavy-duty pallet racking device. In use, the active adjustment structure 100 and passive support structure 200 are connected to two adjacent racks. The hook plate 120 is connected to the clamping plate 230. The clamping plate 230 is in a stretched state based on the spring return assembly 220. When the rack connected to the active adjustment structure 100 tilts, the hook plate 120 tilts downwards, breaking the connection with the clamping plate 230. The clamping plate 230 retracts, and the bottom extension plate 231 impacts the limiting plate 242. The limiting plate 242 rotates, breaking the contact between it and the limiting ring 262. This causes the compression spring 261 to release, quickly ejecting the limiting ring 262 and the support rod 250 to support the tilted rack. This embodiment is a preferred embodiment, but is not limited thereto. Those skilled in the art can easily understand the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
