Description

Technical Field

[0001] This utility model belongs to the field of storage rack technology, specifically relating to a cargo anti-tipping device for warehouse racks. Background Technology

[0002] In the modern logistics warehousing sector, storage racks, as core equipment for cargo storage, have always been a key focus of the industry regarding safety and stability. With the diversification of stored goods and the continuous increase in stacking height, traditional storage racks often pose safety hazards when dealing with irregularly stacked goods and high-frequency access operations due to insufficient structural stability and simplistic anti-tipping protection mechanisms. While some existing anti-tipping devices can achieve basic cargo blocking functions, they generally suffer from poor adjustment flexibility, insufficient structural adaptability, and a lack of intelligent monitoring, making it difficult to meet the anti-tipping protection needs of goods of different heights and specifications. Furthermore, the main structure of the racks is prone to deformation under long-term loads, further exacerbating the risk of cargo tipping.

[0003] To address the aforementioned issues, existing technologies attempt to improve stability by adding fixed baffles or simple mechanical locking structures. However, such solutions have two major technical bottlenecks: First, fixed or semi-fixed anti-tipping components cannot be dynamically adjusted according to the actual height of the goods, which can easily create operational obstacles during the loading and unloading of goods, and the anti-tipping function fails when storing low-lying goods. Utility Model Content

[0004] The purpose of this utility model is to provide a cargo anti-tipping device for warehouse racks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cargo anti-tipping device for warehouse racks, comprising:

[0006] The side stabilizing brackets are provided in two. Each side stabilizing bracket has symmetrical reinforcing rods on its inner side for tightening and reinforcing the storage rack. The two side stabilizing brackets are provided with goods placement plates at equal intervals from top to bottom between them. The support uprights in each side stabilizing bracket are provided with anti-tipping lock blocks on their outer sides via vertical sliding rods.

[0007] The cargo placement platform is equipped with lifting anti-tilt plates that are linked to the anti-tilt lock blocks for lifting and adjusting. The lifting anti-tilt plates are provided with lifting grooves on both sides to allow the lifting anti-tilt plates to move up and down on the anti-tilt lock blocks for loading and unloading cargo and to prevent tipping.

[0008] Preferably, the vertical slide bar is vertically installed on the front and rear ends of the outer side of each side stabilizing bracket, and the anti-tilt lock block is slidably installed on the vertical slide bar. The outer side of the anti-tilt lock block is threaded with a locking bolt for sliding locking the anti-tilt lock block. The sliding cooperation between the vertical slide bar and the anti-tilt lock block allows the anti-tilt lock block to be freely adjusted in the vertical direction according to the height of the goods.

[0009] Preferably, the anti-tilt lock block has an L-shaped structure, and one end of the anti-tilt lock block extends to one side of the supporting column in each side stabilizing bracket, thereby achieving a close fit with the supporting column of the side stabilizing bracket and enhancing the stability of the overall structure.

[0010] Preferably, directional rods are vertically provided in the lifting grooves on both sides of the lifting anti-tilt plate. A directional slider slides through the directional rods, and a reset elastic element is sleeved at one end of the directional rod to automatically move the lifting anti-tilt plate upward after it is pulled down to protect the cargo from tipping. This provides a stable lifting guide for the lifting anti-tilt plate and ensures that it will not deviate during the lifting process.

[0011] Preferably, one end of the anti-tilt lock block is fixed to one end of the directional slider, so that the anti-tilt lock block drives the lifting anti-tilt plate to slide and lock according to the height of the goods. By fixing the anti-tilt lock block to the directional slider, the linkage control of the lifting anti-tilt plate by the anti-tilt lock block is realized.

[0012] Preferably, the cargo placement board is provided with blocking strips at both the front and rear, and the surface of the cargo placement board is provided with an anti-slip textured surface to prevent the cargo from slipping. The blocking strips at the front and rear of the cargo placement board can limit the cargo from the front and rear directions when the cargo is placed, preventing the cargo from sliding back and forth.

[0013] Preferably, the reinforcing tension rod includes a rotating sleeve rod with internal threads and a tension thread rod with threads. One end of the rotating sleeve rod is fitted with a bearing seat, and the bearing seat is fixed inside one side of each side stabilizing bracket. One end of the tension thread rod is threaded onto the inner side of one end of the rotating sleeve rod, and the other end of the tension thread rod is fixed to one side of the support upright in the side stabilizing bracket for tightening and reinforcing the storage rack. The extension and retraction of the tension thread rod can be adjusted by rotating the rotating sleeve rod according to the actual stress on the rack, thereby tightening and reinforcing the two side stabilizing brackets.

[0014] Preferably, tilt sensors are embedded and fixed at the front and rear of the side stabilizing bracket, and pressure sensors are embedded at the end of the cargo placement plate. The tilt sensors and pressure sensors are connected to an external PLC controller to realize intelligent monitoring and early warning of the status of the storage rack and cargo, which greatly improves the safety and reliability of warehousing operations.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are: the anti-tipping device for the warehouse rack,

[0016] By sliding the vertical slide bar and the anti-tilt lock block together, and with the secure locking bolt, the anti-tilt lock block can be freely adjusted according to the height of the goods, and drives the lifting anti-tilt plate to rise and fall synchronously. This effectively solves the problem of protection and adaptation for goods of different heights, and eliminates the functional limitations of fixed or semi-fixed components.

[0017] The L-shaped anti-tipping and slip-locking blocks fit tightly against the side stabilizing bracket support poles, evenly distributing the lateral pressure of the goods. The reinforced tension rods utilize the threaded transmission between the rotating sleeve rod and the tension threaded rod, allowing for adjustable extension and retraction to tighten the stabilizing brackets on both sides. These dual measures enhance the overall structural strength of the rack, suppress deformation under long-term loads, and significantly improve the stability and service life of the rack.

[0018] The lifting anti-tilt plate, together with the directional upright, directional slider and reset elastic element, automatically avoids and quickly resets when goods are picked up or placed, ensuring convenient operation; the fixed connection between the anti-tilt lock block and the directional slider realizes the linkage control of the lifting anti-tilt plate, simplifies the adjustment process and greatly improves the efficiency of warehousing operations.

[0019] By embedding tilt sensors and pressure sensors in the side stabilizing brackets and cargo placement plates, and connecting them to an external PLC controller, the tilt angle of the shelves and the load-bearing pressure of the goods can be monitored in real time. Once an abnormality is detected, an alarm will be issued or the equipment will be activated quickly, realizing intelligent monitoring and early warning. This fills the gap in safety monitoring of traditional technologies and provides comprehensive protection for the safety of warehousing operations. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a cargo anti-tipping device for warehouse racks, comprising:

[0027] The side stabilizing bracket 1 is integrally formed from high-strength steel, possessing excellent compressive and deformation resistance. Its structural design conforms to mechanical principles, effectively distributing the load borne by the entire shelving unit. Two side stabilizing brackets 1 are provided, arranged parallel and symmetrically on both sides of the storage rack. Each side stabilizing bracket 1 has symmetrically arranged reinforcing tension rods 2 on its inner side for tightening and reinforcing the storage rack. The installation of the reinforcing tension rods 2 allows for flexible adjustment of the rack's stability based on its actual load-bearing capacity. Between the two side stabilizing brackets, equidistant from top to bottom, are goods placement plates 3 for placing goods. The spacing of the goods placement plates 3 can be customized according to the height specifications of common goods to meet the storage needs of goods of different sizes. Each side stabilizing bracket 1 has an anti-tipping locking block 5 vertically sliding on its outer side via a vertical sliding rod 4. The vertical sliding rod 4 is connected to the supporting upright by welding or high-strength bolts to ensure a secure connection.

[0028] The cargo placement plate 3 is equipped with lifting anti-tilt plates 6 at the front and rear, which are linked to the anti-tilt lock blocks 5 for height adjustment. The outer surface of the lifting anti-tilt plate 6 is provided with handles to facilitate the lifting and placing of goods by pulling down the lifting anti-tilt plate 6. The lifting anti-tilt plate 6 is made of lightweight but high-strength alloy material, which can effectively prevent goods from tipping over and is easy to operate. The lifting anti-tilt plate 6 is provided with lifting grooves 7 on both sides, which allow the lifting anti-tilt plate 6 to move up and down on the anti-tilt lock blocks 5 to pick up and place goods and prevent tipping. The inner wall of the lifting grooves 7 is finely polished to ensure smooth sliding of the lifting anti-tilt plate 6.

[0029] Vertical slide bars 4 are vertically mounted on the outer front and rear ends of each side stabilizing bracket 1, and anti-tilt lock blocks 5 are slidably mounted on vertical slide bars 4. A precision guide rail fit structure is used between the two to ensure smooth sliding and accurate positioning of the anti-tilt lock blocks 5. A locking bolt 8, made of high-strength stainless steel, is threaded through the outer side of the anti-tilt lock block 5 to lock it in place. The bolt 8 has good rust resistance and its thread design conforms to standard specifications, providing reliable locking force.

[0030] The anti-tilt locking block 5 has an L-shaped structure. This structural design enhances the connection stability between the anti-tilt locking block 5 and the side stabilizing bracket 1. One end of the anti-tilt locking block 5 extends to one side of the supporting column in each side stabilizing bracket 1 and is tightly fixed by bolts or welding to ensure effective force transmission.

[0031] Both sides of the lifting anti-tilt plate 6 are vertically equipped with directional rods 9 in the lifting slide grooves 7. The directional rods 9 are made of high-rigidity metal rods with anti-corrosion treatment on their surfaces. A directional slider 10 slides through the directional rod 9. The high precision of the fit between the directional slider 10 and the directional rod 9 ensures that the lifting anti-tilt plate 6 will not wobble during lifting. Furthermore, one end of the directional rod 9 is sleeved with a reset elastic element 11 that automatically moves the lifting anti-tilt plate 6 upward after it is pulled down to protect the cargo from tipping. The reset elastic element 11 is preferably a compression spring, and its elastic coefficient has been rigorously calculated and tested to provide sufficient reset force while meeting the lifting requirements.

[0032] One end of the anti-tilt lock block 5 is fixed to one end of the directional slider 10. It adopts a high-strength connection method, such as riveting or high-strength adhesive connection, so that the anti-tilt lock block 5 drives the lifting anti-tilt plate 6 to slide and lock according to the height of the goods, so as to achieve precise protection of goods of different heights.

[0033] The cargo placement platform 3 is equipped with baffles 12 at both the front and back. The height of the baffles 12 is designed according to the size of common goods, which can effectively prevent the goods from sliding back and forth on the placement platform. In addition, the surface of the cargo placement platform 3 is provided with an anti-slip textured surface 13 to prevent the goods from slipping. The anti-slip textured surface 13 is formed by a special surface treatment process, which has good wear resistance and can maintain the anti-slip effect for a long time.

[0034] The reinforcing tension rod 2 includes a rotating sleeve rod 14 with internal threads and a threaded tensioning threaded rod 15. One end of the rotating sleeve rod 14 is fitted with a bearing seat 16, which uses a high-precision ball bearing to effectively reduce friction during rotation. The bearing seat 16 is fixed to one side of each side stabilizing bracket 1 and is tightly connected to the side stabilizing bracket 1 by bolts. One end of the tensioning threaded rod 15 is threaded onto the inner side of one end of the rotating sleeve rod 14, with high thread precision to ensure accurate adjustment. The other end of the tensioning threaded rod 15 is fixed to one side of the support upright in the side stabilizing bracket 1 for tightening and reinforcing the storage rack. The rack can be flexibly reinforced according to actual needs.

[0035] Tilt sensors 17 are embedded and fixed at the front and rear of the side stabilizing bracket 1. These sensors 17 possess high precision and sensitivity, enabling real-time and accurate monitoring of changes in the tilt angle of the rack. Pressure sensors 18 are embedded at the ends of the goods placement platform 3, accurately detecting the load-bearing pressure on the platform. The tilt sensors 17 and pressure sensors 18 are connected to an external PLC controller, transmitting data via a dedicated signal cable to ensure data stability and accuracy, thus enabling intelligent monitoring and early warning of the warehouse racking and goods status.

[0036] In this anti-tipping device for warehouse racking, tilt sensors 17 are embedded and fixed at the front and rear of the side stabilizing bracket 1. Honeywell's QTI series tilt sensors can be used, which offer ultra-high measurement accuracy of ±0.005° and a resolution of up to 0.001°, enabling real-time and accurate monitoring of the racking's tilt angle changes in the X and Y axes. Their working principle is based on MEMS technology, incorporating a high-precision accelerometer chip. By detecting the component of gravitational acceleration on the sensor's sensitive axis, the tilt angle is calculated. When the racking tilts due to uneven stacking of goods, ground subsidence, or external impact, the tilt sensor 17 quickly converts the angle data into an electrical signal, which is transmitted to an external PLC controller via a dedicated RS485 communication cable. The PLC controller has a preset safety angle threshold (e.g., ±3°). Once the monitored data exceeds the threshold, an audible and visual alarm system is immediately triggered, and an alarm message is sent to the warehouse management system to remind staff to handle the situation promptly and prevent the racking from tipping over due to increased tilt.

[0037] The pressure sensor 18 embedded at the end of the cargo placement plate 3 is recommended to be the PW20AC3M1 series pressure sensor from HBM, Germany. This sensor has a range of 0-500kg, a comprehensive accuracy of ±0.05%FS, and excellent long-term stability and resistance to off-center loading. Based on the strain gauge principle, when goods are placed on the cargo placement plate 3, the elastic body of the pressure sensor 18 undergoes slight deformation, and the resistance value of the strain gauge attached to the elastic body changes accordingly. This resistance change is converted into a voltage signal output through a Wheatstone bridge circuit. The pressure sensor 18 is connected to the PLC controller via a shielded cable, uploading the pressure data borne by the cargo placement plate 3 in real time. The PLC controller can analyze the data from multiple pressure sensors 18 on the same shelf layer to determine whether the goods are stacked evenly. If local pressure is too high or the pressure distribution is abnormal, the system will issue an early warning to prompt staff to adjust the placement of goods. Simultaneously, according to a preset program, it can adjust the anti-tipping plate 6 accordingly, enhancing the protection of unstable goods and effectively preventing tipping accidents caused by the shift of the cargo's center of gravity.

[0038] Specifically, in use, the side stabilizing bracket 1 is reinforced as a whole by symmetrically arranged reinforcing tension rods 2. The reinforcing tension rods 2 consist of a rotating sleeve rod 14 with internal threads and a threaded tension rod 15. One end of the rotating sleeve rod 14 is fixed to the inside of the side stabilizing bracket 1 via a bearing seat 16. One end of the tension rod 15 is screwed into the rotating sleeve rod 14, and the other end is fixed to the other side stabilizing bracket 1. When the rack needs reinforcement, the operator rotates the rotating sleeve rod 14, using the threaded transmission principle to extend and retract the tension rod 15, thereby adjusting the distance between the two side stabilizing brackets 1, tightening the entire rack, enhancing its structural stability, effectively resisting rack deformation caused by factors such as cargo weight and storage / retrieval operations, and providing a stable foundation support to prevent cargo from tipping over.

[0039] Each side stabilizing bracket 1 has vertically mounted sliding rods 4 at its front and rear ends, providing a vertical sliding track for the anti-tilt lock block 5. When dealing with goods of different heights, the operator loosens the locking bolts 8 on the outside of the anti-tilt lock block 5, allowing it to slide freely up and down along the vertical sliding rods 4. Since one end of the anti-tilt lock block 5 is fixedly connected to the directional slider 10, and the directional slider 10 slides in conjunction with the directional uprights 9 in the lifting slide grooves 7 on both sides of the lifting anti-tilt plate 6, the height adjustment of the anti-tilt lock block 5 will synchronously drive the lifting anti-tilt plate 6 to move up and down until the height of the lifting anti-tilt plate 6 matches the height of the goods. Then, the locking bolts 8 are tightened to lock the anti-tilt lock block 5 in the appropriate position, ensuring that the lifting anti-tilt plate 6 stably provides lateral protection for the goods.

[0040] During the loading and unloading of goods, the lifting anti-tilt plate 6 can flexibly avoid obstacles via the lifting slides 7 on both sides. When loading or unloading goods, the operator pulls the lifting anti-tilt plate 6 downwards, and the directional slider 10 slides down along the directional pole 9. At the same time, it compresses the reset elastic element 11 sleeved at one end of the directional pole 9, causing the lifting anti-tilt plate 6 to descend and avoid obstructing the loading and unloading operation. After loading or unloading is completed, the reset elastic element 11 releases its elastic potential energy, pushing the directional slider 10 to automatically move the lifting anti-tilt plate 6 upwards to reset, thus blocking the goods again and preventing them from tipping over.

[0041] The cargo placement platform 3 serves as a basic load-bearing and limiting element in the process of preventing cargo from tipping over. The front and rear blocking strips 12 can physically limit the cargo from the front and rear directions when it is placed, preventing the cargo from sliding back and forth; at the same time, the anti-slip textured surface 13 of the cargo placement platform 3 increases the friction between the cargo and the platform, further stabilizing the cargo and ensuring that it remains stable on the platform, reducing the risk of tipping over due to the cargo sliding itself.

[0042] The tilt sensors 17 embedded at the front and rear of the side stabilizing bracket 1 and the pressure sensors 18 embedded at the end of the goods placement plate 3 constitute the intelligent monitoring system of this device. The tilt sensors 17 monitor the tilt angle of the rack in real time, while the pressure sensors 18 detect the load-bearing pressure on the goods placement plate 3. Both transmit the real-time collected data to an external PLC controller, which analyzes and processes the data using a preset algorithm. When the rack tilt angle exceeds the safety threshold, or when the load-bearing pressure on the goods placement plate 3 fluctuates abnormally, the PLC controller will quickly issue an alarm and can trigger relevant equipment according to a preset program (such as stopping storage and retrieval operations, activating emergency reinforcement devices, etc.), realizing intelligent monitoring and early warning of the status of the warehouse racks and goods, taking timely measures before the goods tip over, and ensuring the safety of warehouse operations.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
