Description

Technical Field

[0001] This application relates to the field of warehousing and logistics technology, and in particular to an anti-tipping early warning structure for intelligent warehouse racks. Background Technology

[0002] In the modern warehousing and logistics industry, racking is an essential storage device used to store various goods. With the continuous expansion of warehousing scale and the increase in the density of goods storage, the stability of racking has become crucial.

[0003] However, in actual use, due to uneven stacking of goods, external impact, ground subsidence and other reasons, the shelves are prone to tilting. If they are not detected and dealt with in time, they may tip over, causing serious property damage and personal injury.

[0004] Currently, some warehouses use manual inspections to check the stability of shelves. However, this method is inefficient, costly, and makes it difficult to monitor the status of shelves in real time, posing significant safety hazards. Therefore, an anti-tipping early warning structure for intelligent warehouse shelves is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-tipping early warning structure for intelligent warehouse racks to solve the problems mentioned in the background art.

[0007] An anti-tipping early warning structure for an intelligent warehouse rack includes a rack body, an audible and visual alarm fixedly installed on the outer wall of the rack body, two bearing plates fixedly connected to the inner walls of the bottom two sides of the rack body, and a floating triggering mechanism for triggering the audible and visual alarm installed above the two bearing plates.

[0008] The floating trigger mechanism includes a top plate, connecting rods, a fixed block, and a return spring. The connecting rods are arranged in two groups, each group containing two connecting rods, which are symmetrically inclined. The top of each connecting rod is rotatably connected to a connector. The tops of the connectors are connected to the bottom of the top plate via universal joints. The bottom of each connecting rod is rotatably connected to a connecting block. A trigger rod is fixedly connected to the outer wall of every two connecting blocks facing away from each other. The trigger rod is slidably connected to the outer wall of the fixed block, and the return spring is sleeved on the outer wall of the trigger rod.

[0009] Preferably, guide rails are fixedly connected to the top outer walls of the two bearing plates, and two sliders are slidably connected to the outer walls of the guide rails. The connecting block is fixedly connected to the top outer wall of the sliders.

[0010] Preferably, multiple fixing blocks are fixedly connected to the top outer wall of the bearing plate, with two fixing blocks distributed at both ends of the guide rail, and the reset spring is located between the fixing blocks and the connecting blocks.

[0011] Preferably, multiple mounting plates are fixedly connected to the top outer walls of the two bearing plates. A trigger switch is installed on the outer wall of the mounting plate. The trigger switch corresponds to the end of the trigger rod away from the connecting block. The trigger switch is electrically connected to the audible and visual alarm.

[0012] Preferably, the top plate has a U-shaped structure, with grooves on its two outer walls, and sliding rods slidably connected to the inner walls of the two grooves, with movable connecting rods movably connected to both ends of the two sliding rods.

[0013] Preferably, the bottom ends of each pair of movable connecting rods are rotatably connected to a fixing plate via a bearing seat, and the outer wall of the fixing plate is provided with multiple mounting holes.

[0014] Preferably, a telescopic rod is fixedly connected to the outer wall of the fixed block facing the connecting block, and the telescopic end of the telescopic rod is fixedly connected to the outer wall of the slider to limit the sliding range of the slider.

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses an anti-tipping early warning structure for intelligent warehouse racking. (Refer to...) Figure 1-3 An anti-tipping early warning structure for an intelligent warehouse rack includes a rack body 1. The rack body 1 serves as the core load-bearing frame and is welded from high-strength steel. An audible and visual alarm 22 is fixedly installed on its outer wall by bolts. The alarm is an industrial-grade waterproof model to ensure stable operation in a humid warehouse environment. Two load-bearing plates 2 are fixedly connected to the inner walls on both sides of the bottom of the rack body 1 by welding to provide rigid support for subsequent components.

[0024] The core components of the floating trigger mechanism include a top plate 9, connecting rods 6, a fixing block 14, and a trigger rod 15. The multiple connecting rods 6 are divided into two groups, with two connecting rods 6 in each group symmetrically and inclinedly distributed. The two groups of connecting rods 6 correspond to the two sides of the rack body 1, respectively. The top of the connecting rods 6 are rotatably connected through a connector 7. The connector 7 has a U-shaped groove structure and an internal bronze bushing to reduce friction. The top of the connector 7 is connected to the bottom of the top plate 9 through a universal joint 8. The universal joint 8 adopts a cross-shaft structure, which can achieve multi-angle rotation and ensure that the top plate 9 can flexibly adjust its posture when subjected to force.

[0025] The bottom end of the connecting rod 6 is rotatably connected by the connecting block 5. The connecting block 5 is a rectangular cast steel part. Its connecting shaft with the connecting rod 6 is made of 40Cr material and has been heat treated. The outer walls of every two connecting blocks 5 are fixedly connected to the trigger rod 15 by internal hex bolts. The fixing block 14 is a square cast iron part, which is fixed to the top of the bearing plate 2 by expansion bolts. Its center has a through hole that matches the trigger rod 15 to ensure that the trigger rod 15 slides smoothly. The return spring 16 is a cylindrical helical compression spring, which is sleeved on the outer wall of the trigger rod 15 and its two ends are in contact with the fixing block 14 and the connecting block 5 respectively.

[0026] The top outer walls of the two bearing plates 2 are fixedly connected to the guide rails 3 by bolts. The guide rails 3 are made of dovetail steel rails. The slider 4 is made of polytetrafluoroethylene and has built-in ball bearings. The bottom is provided with a groove that matches the guide rails 3, so that it can slide along the axial direction of the guide rails 3. The connecting block 5 is fixed to the top outer wall of the slider 4 by welding to ensure the stability of the connecting block 5 when it moves with the slider 4.

[0027] Multiple fixing blocks 14 are distributed in groups of two and are fixed to the top outer wall of the bearing plate 2 by bolts. Each group of fixing blocks 14 is located at both ends of the guide rail 3. The two ends of the return spring 16 are in close contact with the inner wall of the fixing block 14 and the outer wall of the connecting block 5, respectively.

[0028] Multiple mounting plates 18 are welded to the top outer wall of the bearing plate 2. The mounting plates 18 are L-shaped angle steel. The trigger switch 19 is fixed to the outer wall of the mounting plate 18 with screws. The trigger switch 19 is a limit switch. The distance between its trigger contact and the end of the trigger rod 15 is set to 5mm to ensure that the trigger rod 15 can accurately touch when it slides to the position. The trigger switch 19 is electrically connected to the audible and visual alarm 22 through an RVV type cable. The cable is passed through a pre-set wire hole inside the main body of the shelf 1 to avoid damage from external forces.

[0029] The top plate 9 adopts a U-shaped structure. The sliding grooves 10 on both outer walls are through grooves. The groove width is 0.5mm larger than the diameter of the sliding rod 11. The sliding rod 11 is made of chrome-plated round steel with a diameter of 10mm. It can slide freely in the sliding groove 10 without any jamming during the sliding process. The two ends of the two sliding rods 11 are movably connected to the movable connecting rod 12 through bushings. The bushings are filled with grease to reduce rotational friction.

[0030] The bottom ends of each pair of movable connecting rods 12 are rotatably connected to the fixed plate 13 via a bearing seat. The bearing seat is a seated bearing to ensure flexible rotation. The fixed plate 13 is a square steel plate with four 12mm diameter mounting holes on its outer wall. It is fixed to the ground with expansion bolts to provide a stable ground support point for the entire triggering mechanism.

[0031] The outer wall of the fixed block 14 facing the connecting block 5 is connected to the telescopic rod 17 by a thread. Its telescopic end is connected to the outer wall of the slider 4 by a fisheye connector. When the slider 4 slides to the maximum stroke, the telescopic rod 17 is in a fully extended state, which restricts the slider 4 from continuing to move and avoids excessive sliding of the trigger rod 15, which could cause damage to the components.

[0032] Two sliding jaw frames 20 are welded to the outer wall of the opposite side of the bearing plate 2. The sliding jaw frame 20 has a U-shaped groove structure. The connecting piece 7 is welded with a limiting post 21 on the side facing the sliding jaw frame 20, which can slide smoothly in the U-shaped groove of the sliding jaw frame 20. During the sliding process, the gap with the groove wall is uniform, ensuring that the connecting rod 6 moves along the preset trajectory when it rotates, and avoiding lateral deviation.

[0033] The implementation principle of the anti-tipping warning structure of the intelligent warehouse rack in this application embodiment is as follows: When the rack body 1 tilts, the bearing plate 2 on one side of its bottom will tilt in the front and back direction along with the rack body 1. Since the bearing plate 2 is fixedly connected to the rack body 1, during the tilting process, it will pry up the connecting rod 6, connecting piece 7 and other components above it, thereby lifting up the corresponding end of the top plate 9.

[0034] Because the two fixed plates 13 are firmly fixed to the ground through the mounting holes, when one end of the top plate 9 is lifted, the fixed plate 13 generates a traction force on the sliding rod 11 through the movable connecting rod 12. Under the action of the traction force, the sliding rod 11 slides along the sliding groove 10 of the top plate 9. During the movement, the sliding rod 11 will also generate a downward squeezing force, driving one end of the top plate 9 to press down.

[0035] One end of the top plate 9 moves downward under pressure, and the pressure is transmitted to the connecting rod 6 through the universal joint 8 and the connector 7. After the connecting rod 6 is subjected to force, its bottom end will expand outward, pushing the connecting block 5 to slide outward along the guide rail 3 with the slider 4. When the connecting block 5 slides, it simultaneously drives the trigger rod 15 to slide in the through hole of the fixed block 14. At this time, the return spring 16 is compressed and generates a reverse elastic force.

[0036] As the trigger rod 15 continues to slide outward, its end gradually approaches and eventually touches the trigger switch 19 on the mounting plate 18. After the trigger switch 19 is triggered, it transmits an electrical signal to the audible and visual alarm 22 through a wire. After receiving the signal, the audible and visual alarm 22 immediately emits a clear audible and visual alarm signal to remind the on-site staff that the main body of the shelf 1 has tilted and needs to be checked and dealt with in time to avoid the tilting degree from worsening and causing the shelf to tip over.

[0037] Once the tilt of the main body 1 of the shelf is corrected, the elastic force of the reset spring 16 pushes the connecting block 5, slider 4 and other components to slide back and reset. The trigger rod 15 separates from the trigger switch 19, the trigger switch 19 stops sending signals, the audible and visual alarm 22 stops alarming, and the entire anti-tipping warning structure returns to its initial standby state, waiting for the next tilt detection.
