Description
Technical Field
[0001] This utility model belongs to the field of shelving technology, specifically relating to a storage shelving unit with anti-tipping function. Background Technology
[0002] Currently, heavy-duty storage racks are widely used in various warehouses. However, due to misaligned stacking, uneven loading, or long-term overloading, the overall center of gravity of the racks is easily unbalanced, leading to tilting or even collapse. In warehouse environments, to maximize space utilization, racks are usually arranged in close rows. Once one row of racks tilts, it can easily trigger a chain reaction, impacting adjacent racks and causing large-scale, continuous overturning accidents, resulting in huge economic losses and safety hazards. Traditional rack structures themselves lack effective active anti-tipping mechanisms, typically relying only on increasing structural strength or reinforcing the foundation to passively resist tilting. This is insufficient to cope with sudden instability and cannot provide early warning or intervention in the initial stages of tilting, failing to prevent subsequent chain collapses. Therefore, this utility model proposes a storage rack with anti-tipping functionality to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a storage rack with anti-tipping function, which can solve the above-mentioned technical problems.
[0004] The specific technical solution adopted by this utility model is as follows: This utility model provides a storage rack with anti-tipping function, including a rack body and side support mechanisms arranged on both sides of the rack body. Multiple connecting rods are arranged on the two side support mechanisms on the same side, and a horizontal sensor installed at the bottom corner of the rack body is arranged on the lower side of the side support mechanism. The shelving body includes uprights and crossbeams and cross braces mounted on the uprights. A mounting plate is installed on the upper cross brace, and a level sensor is installed on the mounting plate. A controller electrically connected to the level sensor is installed on the middle cross brace.
[0005] Preferably, the side support mechanism includes a side support rod, a hinge seat, and two fixed seats. The side support rod is located on the outer side of the column, and the upper end of the side support rod is hinged to the hinge seat. The hinge seat is provided with two first fasteners, and the hinge seat is installed on the side of the column through the first fasteners. The two fixed seats are provided with an elastic pushing mechanism that is linked to the side support rod.
[0006] Preferably, the side support rod has multiple through holes, and the connecting rod passes through the corresponding through holes on two side support rods. The two ends of the connecting rod have openings, and cotter pins are used to prevent it from leaving the through holes.
[0007] Preferably, the elastic push mechanism includes a pin and an expansion frame. The upper and lower ends of the pin pass through two fixed seats and are fastened with nuts to prevent detachment. A second fastener is provided on the fixed seat, and the fixed seat is installed on the side of the column by the second fastener.
[0008] Preferably, the expansion frame is disposed between the side support rod and the pin, and an elastic element and a sliding sleeve are sleeved on the pin. The elastic element and the sliding sleeve are both disposed between two fixed seats, and the sliding sleeve is located below the elastic element. One end of the expansion frame is hinged to the sliding sleeve, and the other end is hinged to the side support rod.
[0009] Preferably, the side support rod is supported by the expansion frame and the angle between it and the column is 15–25°, and the horizontal distance between the lower end of the side support rod and the column is 800–1200 mm when the side support rod is unfolded.
[0010] Preferably, the lower two ends of the shelf body are provided with clamping and mixing devices, the bottom end of the side support rod is provided with a limiting structure that cooperates with the clamping and mixing devices, the clamping and mixing devices are installed on the mounting base, and the mounting base is fixed to the lower side of the column.
[0011] The beneficial effects are: This utility model forms an anti-tipping system through the linkage of a side support mechanism, a horizontal sensor, and a clamping device. This anti-tipping system not only responds quickly and provides reliable support, but also effectively prevents chain collapse accidents caused by the tipping of a single shelf, greatly improving the safety and reliability of the storage system. Moreover, its structural design makes it easy to install and modify on existing shelves, making it convenient to implement and widely applicable. Attached Figure Description

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0015] like Figure 1-3 As shown, a storage rack with anti-tipping function includes a rack body 1 and side support mechanisms 2 arranged on both sides of the rack body 1. Multiple connecting rods 3 are arranged on the two side support mechanisms 2 on the same side. A horizontal sensor 7 is installed at the bottom corner of the rack body 1 on the lower side of the side support mechanism 2. The shelving body 1 includes uprights and beams and cross braces 4 mounted on the uprights. A mounting plate 6 is installed on the upper cross brace 4, and a level sensor 7 is installed on the mounting plate 6. A controller 5 electrically connected to the level sensor 7 is installed on the middle cross brace 4.
[0016] As an optional implementation, the side support mechanism 2 includes a side support rod 21, a hinge seat 22, and two fixed seats 24. The side support rod 21 is located on the outer side of the column, and the upper end of the side support rod 21 is hinged to the hinge seat 22. The hinge seat 22 is provided with two first fasteners 22a, and the hinge seat 22 is installed on the side of the column through the first fasteners 22a. The two fixed seats 24 are provided with elastic pushing mechanisms that are linked to the side support rod 21, so that the upper end of the side support rod 21 forms a rotating connection structure. The side support rod 21 can be adjusted in terms of unfolding angle by means of the elastic pushing mechanism.
[0017] See attached document Figure 2 and attached Figure 3 The side support rod 21 has multiple through holes 21a. The connecting rod 3 passes through the corresponding through holes 21a on the two side support rods 21. The two ends of the connecting rod 3 have openings, and the connecting rod is restricted from leaving the through holes 21a by cotter pins, so that the two side support mechanisms 2 on the same side of the rack body 1 are connected as a whole, thereby enhancing the lateral support stability of the rack body 1.
[0018] Furthermore, the elastic push mechanism includes a pin 23 and an expansion frame 27. The upper and lower ends of the pin 23 pass through two fixed seats 24 and are fastened with nuts to prevent detachment. The fixed seats 24 are provided with second fasteners 24a. The fixed seats 24 are installed on the side of the column by the second fasteners 24a to adapt to the existing rack structure and facilitate the installation of the fixed seats 24.
[0019] Furthermore, the expansion frame 27 is positioned between the side support rod 21 and the pin 23. An elastic element 25 and a sliding sleeve 26 are fitted onto the pin 23. Both the elastic element 25 and the sliding sleeve 26 are positioned between the two fixed seats 24, with the sliding sleeve 26 located below the elastic element 25. One end of the expansion frame 27 is hinged to the sliding sleeve 26, and the other end is hinged to the side support rod 21, allowing the sliding sleeve 26 to slide upwards under the action of the elastic element 25. This causes the expansion frame 27 and the side support rod 21 to fold and retract, entering a side support ready state. Simultaneously, the elastic element 25... The sliding sleeve 26 and the expansion frame 27 apply a downward supporting force to the side support rod 21, enhancing the lateral support effect of the side support rod 21 on the rack body 1. The elastic element 25 uses spring steel wire with a preferred diameter of 5-8mm, a spring mean diameter of 40-60mm, a free length between 300-400mm, a spring stiffness coefficient of approximately 15-25N / mm, and a maximum working compression of not less than 150mm, to ensure that sufficient initial downward thrust can be provided to drive the side support rod 21 to quickly unfold and form effective support with the ground.
[0020] Furthermore, the side support rod 21 is supported by the expansion frame 27 and the angle between it and the upright is 15–25°, preferably 20°. When the side support rod 21 is unfolded, the horizontal distance between its lower end and the upright is 800–1200 mm. When the angle between the side support rod 21 and the upright is 20°, the distance between the side support rod 21 and the upright is 1000 mm. This allows the unfolding angle and distance of the side support rod 21 to adapt to the aisle width between adjacent shelves, making it easy to add and apply to existing shelf systems.
[0021] Furthermore, the lower ends of the rack body 1 are equipped with clamping devices 8, and the bottom of the side support rod 21 is equipped with a limiting structure that cooperates with the clamping device 8. The clamping device 8 is installed on the mounting base 81, and the mounting base 81 is fixed to the lower side of the column, so that the clamping device 8 can limit and fix the side support rod 21 in the state of the elastic element 25 storing force, realizing the trigger linkage function when the rack tilts. The clamping device is a normally closed energized self-holding electromagnet release device. Its selection requirements are: working voltage DC24V (safe voltage), rated holding force not less than 500N, pull-in power of 10W, and release response time less than 100ms, so as to ensure that it can be released instantly after the controller 5 issues the command, releasing the locked side support rod 21.
[0022] The preset linkage control steps in controller 5 are as follows: 1. The system performs a power-on self-test, and the level sensor 7 continuously monitors the levelness data of each bottom corner of the shelf body 1; 2. When the tilt angle of any monitoring point exceeds the preset safety threshold (e.g., 3°), controller 5 determines that it is in an unstable state; 3. Controller 5 immediately sends a power-off command to the electromagnet release device corresponding to the unstable side to release its clamping restriction on the bottom end of the side support rod 21; 4. Driven by the compression spring, the side support rod 21 quickly rotates and unfolds around the upper hinge point until the bottom end firmly touches the ground, forming a rigid support; 5. The system records the alarm event and maintains the support state until manual intervention is performed for manual reset and system restart.
[0023] Using the above structure, when the rack body 1 initially tilts due to uneven load distribution or overload, the level sensor 7 installed on the rack body 1 monitors the change in levelness in real time and transmits the signal to the controller 5; after the controller 5 determines that the tilt angle exceeds the preset safety threshold (e.g., 3°), it immediately sends a power-off command to the normally closed electromagnet release device corresponding to the unstable side; the electromagnet trips within a millisecond response time, releasing the clamping constraint of the bottom limiting structure of the side support rod 21; driven by the elastic potential energy stored in the pre-compressed spring, the side support rod 21 rotates around the upper end The hinge seat 22 quickly rotates outward and downward; the expansion frame 27 unfolds to a predetermined angle (15-25°) under the continuous downward pressure transmitted by the spring through the sliding sleeve 26, so that the bottom end of the side support rod 21 forms a stable support with the ground with a lateral span of 800-1200mm; at the same time, the connecting rod 3 connecting the two side support mechanisms 2 on the same side distributes and transmits the support force to form an integral support structure, effectively resisting the continued tilting of the shelf; the entire linkage process is completed automatically in a very short time, thereby realizing the active anti-tipping function until manual reset operation is performed.
