Description

Technical Field

[0001] This utility model relates to the field of intelligent shelving technology, specifically to an intelligent shelving system that prevents goods from being overweight. Background Technology

[0002] Intelligent shelving that prevents overloading is a warehousing equipment that integrates mechanical structure and sensing technology. By dynamically monitoring the load-bearing weight of the shelving, it automatically triggers an early warning when the load is overloaded, avoiding safety hazards such as shelving damage and cargo tipping caused by overloading, and improving the safety and intelligence level of warehouse management.

[0003] A search revealed Chinese patent CN222273024U, which discloses an intelligent shelving system to prevent overloading. This patent describes an integrated structure where an auxiliary ladder and a shelving unit are combined using an auxiliary mechanism and an electric push rod. Unlike traditional shelving where goods at the top are difficult to retrieve, this new shelving system increases height, allowing for more goods to be placed. An automatic entry and exit auxiliary mechanism is incorporated within the bottom placement slot. One end of the electric push rod is fixed to the placement slot, and the other end is fixed to the base plate inside the auxiliary mechanism. Activating the electric push rod extends or retracts the auxiliary mechanism, allowing users to easily retrieve goods from the top of the shelving while standing on the platform. Furthermore, the lifting support rod at the bottom of the base plate is height-adjustable, ensuring it is in contact with the ground. To distribute the pressure on the auxiliary mechanism and prevent it from collapsing and injuring the user, large and small shelves are set inside the support frame to facilitate the classification and retrieval of goods. Mixing small and large goods can easily lead to the loss of goods. Weighing detectors are installed inside different shelves. When the goods are overweight, an alarm will be sound to prevent the shelves from being damaged due to excessive pressure, thus effectively improving the service life of the shelves. A processor is added to the top of the shelves to improve their intelligence. A facial recognition system can view all the user's goods information and storage and retrieval status, making it easier for users to quickly retrieve goods and increasing the convenience of goods retrieval.

[0004] In this solution, staff can only visually determine if there is overloading. Furthermore, the weight of goods on each shelf is uneven, making it impossible to accurately determine overloading. This leads to problems such as bending, deformation, and collapse of the shelves, reducing their lifespan. To solve this technical problem, this utility model proposes an intelligent shelf that prevents goods from being overloaded. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In this solution, staff can only visually determine if there is overloading. Furthermore, the weight of goods on each shelf is uneven, making it impossible to accurately determine overloading. This leads to problems such as bending, deformation, and collapse of the shelves, reducing their lifespan. To solve this technical problem, this utility model proposes an intelligent shelf that prevents goods from being overloaded.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an intelligent shelf for preventing overweight goods, comprising a base plate and a shelf, wherein the shelf is located above the base plate, and a pair of rotating plates are provided between the shelf and the base plate. A sliding groove is provided inside the base plate, and a slider is slidably connected inside the groove. Both ends of the rotating plates are rotatably connected to the shelf and the slider via positioning rods. A spring is fixedly connected to both sides of the slider. A pressure rod is fixedly connected to the bottom of the shelf. An outer frame is fixedly connected to the top of the base plate, and a triggering device is slidably connected inside the outer frame. An alarm device is fixedly connected to the outer wall of the shelf.

[0009] Preferably, one end of the spring is fixedly connected to the inner wall of the slide groove, and the signal output end of the triggering device is connected to the signal receiving end of the alarm device.

[0010] Preferably, a pair of damping rods are fixedly connected to the top of the base plate, and the other end of each damping rod is fixedly connected to the bottom of the cargo rack. A pair of springs are fixedly connected between the cargo rack and the base plate, and the springs are sleeved on the outer wall of the damping rods.

[0011] Preferably, an airbag is fixedly connected inside the outer frame, and the airbag is located below the triggering device.

[0012] Preferably, a pair of mounting plates are fixedly connected to the outer walls on both sides of the base plate, a bracket is fixedly connected to the top of each mounting plate, and an electric push rod is fixedly connected to the bottom of the other end of the bracket. Four casters are fixed to the bottom of the base plate.

[0013] Preferably, a pair of limiting rods are fixedly connected to both sides of the top of the base plate, and a pair of connecting blocks are fixedly connected to both sides of the outer wall of the cargo rack, with the connecting blocks slidably connected to the outside of the limiting rods.

[0014] (III) Beneficial Effects

[0015] This utility model provides an intelligent shelf to prevent goods from exceeding their weight limit. It has the following beneficial effects:

[0016] (1) The base plate serves as the basic support. The rack is connected to the positioning rod and slider through the rotating plate. The slider slides in the groove. When the rack carries goods, the weight causes the slider to compress the spring and move down. At the same time, the damping rod and the spring work together to buffer. As the weight of the goods increases, the pressure bar at the bottom of the rack gradually presses down on the triggering device in the outer frame, squeezing the airbag. When the pressure exceeds the set threshold, the triggering device activates the alarm device and issues an alarm. This design solves the problem that existing racks cannot automatically monitor overload. Traditional racks rely on manual judgment of weight, which can easily lead to rack deformation or even collapse due to overload. This device can quickly detect weight and alert staff through mechanical transmission and pressure triggering, thereby extending the service life of the rack and ensuring the safety of warehousing operations.

[0017] (2) The casters installed at the bottom of the base plate make the rack move flexibly. The staff can easily push the rack to adjust its position. The bracket on it supports the electric push rod. When the rack needs to be fixed, the electric push rod starts to extend and lift the casters off the ground, so that the base plate is firmly in contact with the ground and forms a rigid support. When it needs to be moved, the electric push rod retracts and the casters touch the ground, restoring the rack's mobility. This design solves the problems of inconvenient movement and fixed height of existing racks. Traditional racks have fixed positions, and adjustments require multiple people to move them. They cannot adapt to goods of different heights and have poor flexibility. This device significantly improves the utilization rate of storage space and the convenience of operation through the linkage of the electric push rod and the casters, and reduces labor costs and the risk of goods handling.

[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] Example 1: An intelligent shelving system for preventing overweight goods includes a base plate 1 and a shelf 2. The shelf 2 is located above the base plate 1. A pair of rotating plates 3 are arranged between the shelf 2 and the base plate 1. The base plate 1 has a groove 6 inside, and a slider 5 is slidably connected inside the groove 6. The two ends of the rotating plates 3 are rotatably connected to the shelf 2 and the slider 5 respectively through positioning rods 4. Springs 7 are fixedly connected to both sides of the slider 5. A pressure rod 11 is fixedly connected to the bottom of the shelf 2. An outer frame 12 is fixedly connected to the top of the base plate 1, and a triggering device 14 is slidably connected inside the outer frame 12. An alarm device 21 is fixedly connected to the outer wall of the shelf 2. The other end of the spring 7 is fixedly connected to... A pair of damping rods 8 are fixedly connected to the top of the bottom plate 1 on the inner wall of the slide 6. The other end of each damping rod 8 is fixedly connected to the bottom of the cargo rack 2. A pair of springs 10 are fixedly connected between the cargo rack 2 and the bottom plate 1, and the springs 10 are sleeved on the outer wall of the damping rods 8. An airbag 13 is fixedly connected inside the outer frame 12, and the airbag 13 is located below the triggering device 14. A pair of limiting rods 16 are fixedly connected to both sides of the top of the bottom plate 1. A pair of connecting blocks 15 are fixedly connected to both sides of the outer wall of the cargo rack 2, and the connecting blocks 15 are slidably connected to the outside of the limiting rods 16. The signal output end of the triggering device 14 is connected to the signal receiving end of the alarm device 21.

[0025] After the goods are placed on the shelf 2, the connecting block 15 moves smoothly down along the limiting rod 16. The weight of the goods is transmitted to the rotating plate 3 through the shelf 2, driving the slider 5 to slide in the groove 6. During this process, the spring 7 is compressed and undergoes elastic deformation, using its rebound force to offset part of the pressure. It works in tandem with the damping rod 8 and the spring 10 to effectively reduce the downward impact of the shelf 2 through damping buffering and elastic support, ensuring the stability of the shelf. As the goods continue to stack, when the weight approaches the critical value, the pressure bar 11 at the bottom of the shelf 2 gradually approaches the triggering device 14, squeezing the airbag 13 inside the outer frame 12. Once the weight exceeds the preset threshold, the triggering device 14 immediately activates the alarm device 21, alerting the staff with sound and light. The entire system, through precise mechanical transmission and pressure triggering logic, significantly reduces the risk of shelf collapse caused by overloading, building a solid safety barrier for warehousing operations.

[0026] Example 2: The difference between this example and Example 1 is that a pair of mounting plates 18 are fixedly connected to the outer walls on both sides of the base plate 1, a bracket 19 is fixedly connected to the top of each mounting plate 18, and an electric push rod 20 is fixedly connected to the bottom of the other end of the bracket 19. Four casters 17 are fixed to the bottom of the base plate 1.

[0027] The bracket 19, mounted on the mounting plate 18, supports the electric push rod 20. The height of the shelving unit 2 can be precisely adjusted by extending and retracting the push rod to accommodate the storage needs of goods of different sizes. The bottom casters 17 provide the shelving unit with flexible movement, allowing staff to easily push it to adjust its position. When the shelving unit needs to be fixed, the electric push rod 20 extends, lifting the casters 17 off the ground and firmly anchoring the shelving unit to provide rigid support. The combination of height adjustment, flexible movement, and stable fixing allows the shelving unit 2 to quickly respond to changes in warehouse layout while maintaining stability during operation, significantly improving the convenience and efficiency of warehouse operations.

[0028] Working principle: The weight threshold corresponds to the elastic and damping forces of spring 7, damping rod 8, and spring 10. When goods are placed on the shelf 2, the shelf 2 moves up and down via connecting block 15 and limiting rod 16. The weight is transmitted to rotating plate 3 through shelf 2, causing slider 5 to slide in groove 6 of base plate 1. Compression spring 7 buffers the downward pressure of shelf 2 through its elasticity. At the same time, damping rod 8 and spring 10 work together to buffer the downward pressure of shelf 2. As the weight of goods gradually increases, pressure rod 11 at the bottom of shelf 2 gradually moves down and presses down trigger device 14, squeezing airbag 13 inside outer frame 12. When the weight of goods exceeds the threshold, the pressure threshold is reached. When a threshold is set, the triggering device 14 triggers the alarm device 21 to issue an alarm, thereby alerting the staff that the load is overloaded. This design, through mechanical linkage and weight triggering mechanism, monitors the weight of goods in real time and issues an early warning, preventing damage to the shelves or safety hazards caused by overloading, and improving work efficiency. The electric push rod 20 is mounted on the mounting plate 18 via the bracket 19, which can adjust the height of the shelf 2. The bottom casters 17 facilitate the movement of the shelf and achieve flexible position adjustment. When it needs to be fixed, the electric push rod 20 is activated to lift the casters 17 off the ground and fix the shelf 2. Through their cooperation, the movement and fixation of the shelf 2 are facilitated.
