Description

Technical Field

[0001] This utility model relates to the field of stacking racks, specifically a ground-protecting stacking rack. Background Technology

[0002] Stacking racks are a type of multi-functional warehousing equipment derived from pallets. They need to be used in conjunction with forklifts. They can be used as static storage racks or dynamic handling tools to realize the unitized flow of goods from storage to distribution. Their biggest feature is that they can be stacked 3 to 4 layers to form a three-dimensional storage mode without the need for traditional racks. They are particularly suitable for rented warehouses, low old warehouses or temporary storage areas in workshops, and can effectively improve space utilization.

[0003] Currently, when using stacking racks, the goods on the inner side are stacked to a relatively high height. This presents a problem: when operators need to retrieve or place goods on the upper layer, they must climb external ladders, which undoubtedly increases the workload of the operators. Therefore, the inventors urgently need to design a stacking rack with a ladder structure to reduce the operators' reliance on external ladders and improve the ease of use of the stacking rack. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a protective ground stacking rack to solve the technical problem of poor convenience for operators to retrieve and place items on the upper layer of the stacking rack.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ground protection stacking rack, including a base frame, with support feet welded at each of the four corners of the base frame, support rods inserted above the support feet, and reinforcement components installed between adjacent support rods; The reinforcement component includes a reinforcement rod, on which an installation rod is welded. An installation sleeve is welded on the base frame at a position opposite to the installation rod. The installation rod is inserted into the installation sleeve. The installation rod is parallel to a support rod on one side. A ladder mechanism is provided between the installation rod and the support rod for operators to climb. The climbing mechanism includes a rotating frame. The two sides of the rotating frame are rotatably connected to the support rod and the mounting rod through positioning pins. The two sides of the rotating frame are provided with movable grooves for the positioning pins to engage. A fixed frame is welded to one side of the mounting rod to limit the angle position of the rotating frame.

[0006] By adopting the above technical solution, the ladder function and the main structure of the stacking rack are organically integrated, which fundamentally eliminates the cumbersome step of operators having to find and move separate ladders, significantly simplifies the operation process of storing and retrieving goods at high levels, and directly improves work efficiency.

[0007] Furthermore, a limiting frame is welded onto the support rod at a position opposite to the end of the reinforcing rod, and the reinforcing rod is engaged with the inner side of the limiting frame by a pin.

[0008] By adopting the above technical solution, this connection is not only convenient to construct and facilitates quick assembly or disassembly on site, but more importantly, it effectively transfers and distributes the force borne by the reinforcing rod to the vertical support rod, greatly enhancing the overall lateral stiffness and stability of the stacking frame, and effectively resisting the frame deformation that may be caused by forklift operation or off-center loading of goods.

[0009] Furthermore, at least two sets of the climbing mechanism are provided on the stacking rack, and they are arranged longitudinally.

[0010] By adopting the above technical solution, a continuous, phased safe climbing path is created for operators, which can effectively reduce fatigue and the risk of falling, and meets the safety regulations for working at heights.

[0011] Furthermore, in the folded state of the rotating frame, one corner of the rotating frame is engaged with the inside of the fixed frame; When the rotating frame is in the unfolded state, it rotates to abut against one side of the fixed frame via the positioning pin.

[0012] By adopting the above technical solution, the specific positioning method of the rotating frame in both folded and unfolded states is defined. In the folded state, one corner of the rotating frame is engaged with the inside of the fixed frame. This mechanism can effectively constrain the structure of the fixed frame to prevent the ladder from unfolding on its own due to vibration or shaking during handling or stacking, thus avoiding accidental damage or collision and ensuring cleanliness and safety during storage and transportation.

[0013] Furthermore, the movable groove has a straight groove structure, and the positioning pin is slidably connected to the movable groove for unlocking or locking the rotating frame and the fixed frame.

[0014] By adopting the above technical solution, the operator only needs to slide or move the positioning pin a short distance along the straight groove to easily release the rotation constraint on the rotating frame. The whole process is simple and intuitive, requires little operating force, and greatly improves the ease of use.

[0015] Furthermore, at least four sets of support cups are provided below the base frame, and the support cups are stacking support components for the stacking rack and the ground or lower stacking rack.

[0016] By adopting the above technical solution, the support cup, as a standard stacking interface, can be precisely fitted with the top of the support foot or support rod on the top of the lower stacking rack, ensuring stable force transmission between the upper and lower racks, preventing slippage and misalignment, and ensuring the safety of three-dimensional storage.

[0017] Furthermore, the reinforcing components and stacking racks are coated with anti-rust paint.

[0018] By adopting the above technical solutions, the storage environment, especially poorly ventilated warehouses or cold storage facilities, may contain a certain amount of humidity or corrosive components in the air. Metal frames exposed to this environment for a long time are prone to electrochemical corrosion, which leads to a decrease in structural strength. The anti-rust paint layer can effectively isolate the steel from contact with humid air, fundamentally delaying the rusting process and significantly extending the service life of the product.

[0019] In summary, the present invention has the following main advantages: 1. This utility model uses a climbing ladder mechanism that is directly integrated into a stable frame composed of support rods and reinforcing components. Operators do not need to rely on or use an external climbing ladder. They can directly use the built-in climbing ladder to store and retrieve goods at heights, simplifying the workflow and reducing labor intensity and time costs. At the same time, the rotating frame of the climbing ladder can be unfolded and folded through the cooperation of the positioning pin and the movable slot. When unfolded, the fixed frame provides reliable support to form a stable climbing path. When folded, it can be compactly stored without taking up space, solving the problems of inconvenient ladder handling, messy storage, and potential safety hazards in traditional operation methods. 2. In this utility model, the reinforcing component is inserted into the mounting sleeve on the base frame via a mounting rod, and the end of the reinforcing rod is engaged with the limiting frame on the support rod via a pin. This structure significantly enhances the overall rigidity and stability of the frame and can effectively resist lateral forces during operation. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this embodiment: A type of protective ground stacking rack, such as Figure 1-5 As shown, it includes a base frame 1, with support feet 2 welded at each of the four corners of the base frame 1, support rods 4 inserted above the support feet 2, and reinforcement components 6 installed between adjacent support rods 4; The reinforcement component 6 includes a reinforcement rod 601, on which an installation rod 602 is welded. An installation sleeve 603 is welded on the base frame 1 at a position opposite to the installation rod 602. The installation rod 602 and the installation sleeve 603 are inserted into each other. The installation rod 602 is parallel to a support rod 4 on one side. A ladder mechanism 7 is provided between the installation rod 602 and the support rod 4 for operators to climb. The climbing mechanism 7 includes a rotating frame 702. The two sides of the rotating frame 702 are rotatably connected to the support rod 4 and the mounting rod 602 through positioning pins 703. The two sides of the rotating frame 702 are provided with movable grooves 704 for the positioning pins 703 to cooperate with. A fixed frame 701 is welded to one side of the mounting rod 602. The fixed frame 701 is used to limit the angle position of the rotating frame 702.

[0024] This design achieves an organic integration of the ladder function with the main structure of the stacking rack, fundamentally eliminating the cumbersome step of operators having to find and move separate ladders. This significantly simplifies the process of storing and retrieving goods at higher levels, directly improving work efficiency. At the same time, the reinforcement component 6, which enhances structural stability, serves as the installation base for the ladder mechanism 7. The mounting rod 602 is inserted into the mounting sleeve 603 of the base frame 1 to form a reliable connection, ensuring that the load-bearing capacity of the ladder mechanism 7 is shared by the sturdy frame body, thus guaranteeing stability and safety during the climbing process.

[0025] See Figure 1 , Figure 2 , Figure 3A limiting frame 5 is welded onto the support rod 4 at a position opposite to the end of the reinforcing rod 601. The reinforcing rod 601 is snapped into the inner side of the limiting frame 5 by a pin. This connection is not only convenient for construction and facilitates quick assembly or disassembly on site, but more importantly, it effectively transfers and distributes the force borne by the reinforcing rod 601 to the vertical support rod 4, greatly enhancing the lateral stiffness and stability of the stacking rack as a whole. It can effectively resist the frame deformation that may be caused by forklift operation or off-center loading of goods. At the same time, the cooperation structure between the limiting frame 5 and the pin constitutes a clear mechanical positioning, preventing the reinforcing rod 601 from accidentally coming off or shifting when under force. This ensures the structural integrity and reliability of the frame system composed of the support rod 4 and the reinforcing component 6 under long-term use, and provides an extremely stable support environment for the ladder mechanism 7 integrated above, further ensuring the safety of climbing operations.

[0026] See Figure 1 , Figure 2 , Figure 3 The climbing mechanism 7 has at least two sets on the stacking rack, arranged longitudinally, creating a continuous, phased safe climbing path for operators. This effectively reduces fatigue and the risk of falls, and complies with safety regulations for working at heights. At the same time, the multi-level climbing mechanism provides greater operational flexibility, eliminating the need for operators to climb from the ground to the top in one go. This not only optimizes the workflow but also reduces excessive load on the lower limb joints, making it suitable for complex warehousing scenarios where various sizes of goods are stored or where frequent access to goods at different levels is required.

[0027] See Figure 4 , Figure 5 When the rotating frame 702 is folded, one corner of the rotating frame 702 is engaged with the inside of the fixed frame 701; When the rotating frame 702 is in the unfolded state, it rotates via the positioning pin 703 until it abuts against one side of the fixed frame 701. This defines the specific positioning method of the rotating frame 702 in both the folded and unfolded states. In the folded state, one corner of the rotating frame 702 engages with the inside of the fixed frame 701. This mechanism effectively constrains the structure of the fixed frame 701, preventing the ladder from unfolding on its own due to vibration or shaking during handling or stacking, thus avoiding accidental damage or collisions and ensuring cleanliness and safety during storage and transportation. Meanwhile, in the unfolded state, the rotating frame 702 rotates via the positioning pin 703 until it abuts against one side of the fixed frame 701. At this time, the fixed frame 701 acts as a solid mechanical limit stop, ensuring that the ladder can stably maintain the optimal tilt working angle after unfolding, providing solid support for the operator.

[0028] See Figure 4 , Figure 5The movable groove 704 has a straight groove structure, and the positioning pin 703 is slidably connected to the movable groove 704. It is used to unlock or lock the rotating frame 702 and the fixed frame 701. The operator only needs to slide or move the positioning pin 703 a short distance along the straight groove to easily release the rotation constraint on the rotating frame 702. The whole process is simple and intuitive, requires little operating force, and greatly improves the convenience of use. At the same time, this sliding locking mechanism itself has a self-locking characteristic. When the positioning pin 703 slides to one end of the movable groove 704 and locks, it ensures that the ladder will not be accidentally released when it is in the unfolded working state. Its reliability is far superior to simple pin or hook methods.

[0029] See Figure 1 , Figure 2 , Figure 3 At least four sets of support cups 3 are installed under the base frame 1. The support cups 3 are stacking supports for the stacking rack and the ground or lower stacking rack. As a standard stacking interface, the support cups 3 can be precisely connected to the top of the support feet 2 or support rods 4 on the top of the lower stacking rack, ensuring stable force transmission between the upper and lower racks, preventing slippage and misalignment, and ensuring the safety of the three-dimensional storage. At the same time, the design of the support cups 3 also indirectly protects the ground. It concentrates the overall weight of the stacking rack and the load of goods to several specific, reinforced contact points, rather than pressing the entire base frame 1 plane onto the ground. This reduces the pressure on the floor. If a buffer pad is installed at the bottom of the support cups 3, the pressure can be further distributed, and noise and vibration can be reduced. It is suitable for modern warehouses with high requirements for floor conditions.

[0030] See Figure 1 , Figure 2 , Figure 3 Component 6: The surface of the stacking rack is coated with anti-rust paint. In storage environments, especially poorly ventilated warehouses or cold storage facilities, there may be a certain amount of humidity or corrosive components in the air. Metal racks exposed to this environment for a long time are prone to electrochemical corrosion, which leads to a decrease in structural strength. The anti-rust paint layer can effectively isolate the steel from contact with humid air, fundamentally delaying the rusting process and significantly extending the service life of the product. At the same time, a high-quality surface coating can also improve the overall appearance quality of the product, making the stacking rack look cleaner and more professional. Different colors can also be used to distinguish shelves of different load-bearing levels, different departments, or different uses, assisting in the visual management of the warehouse.

[0031] The implementation principle of this embodiment is as follows: The stacking rack uses the base frame 1 as the bearing foundation. The support feet 2 welded at the four corners and the support cups 3 at the bottom together form a stable ground support and stacking interface. The support rods 4 are inserted into the support feet 2 to form the main structure of the frame. The stability is achieved by the reinforcement component 6. The mounting rod 602 in the reinforcement rod 601 is inserted into the mounting sleeve 603 on the base frame 1 for fixation. The two ends are connected to the limiting frame 5 on the support rod 4 by pins, thereby rigidly connecting the adjacent support rods 4 into one.

[0032] The core innovation lies in the climbing mechanism 7, whose rotating frame 702 is rotatably connected to the support rod 4 and the mounting rod 602 via a positioning pin 703. When climbing is required, the operator slides the rotating frame 702 to move the positioning pin 703 within the movable slot 704, thereby unlocking the rotating frame 702 from the fixed frame 701. The rotating frame 702 is then rotated downwards and unfolded until it abuts against one side of the fixed frame 701 welded to the mounting rod 602. At this point, the rotating frame 702 forms a stable and inclined ladder for climbing, providing the operator with a large number of stepping points. After the operation is completed, the rotating frame 702 can be folded upwards, with its top corner inserted into the fixed frame 701 for compact storage without affecting the stacking function of the stacking rack. The entire device is coated with anti-rust paint to ensure durability.
