Description

Technical Field

[0001] This invention relates to the field of warehouse racking locking technology, specifically a heavy-duty anti-deviation intelligent warehouse racking locking mechanical structure. Background Technology

[0002] Heavy-duty anti-deviation intelligent storage racks are advanced steel structure systems designed specifically for three-dimensional storage scenarios that bear large tonnage goods and need to cope with frequent inbound and outbound impacts and uneven loads. Their core feature is that they use high-strength columns and a rigid locking base as the foundation, and integrate a multi-source sensor network, such as inclinometers, strain gauges and laser displacement sensors, to monitor the verticality of the racks, node deformation and foot displacement in real time.

[0003] In existing technology, when mechanically locking the bottom, adjustable anchor bolts and anti-loosening locking are used: double nuts for anti-loosening, eccentric self-locking washers or hydraulic tensioning sleeves are used, along with pre-embedded steel plates at the bottom, and quantitative locking is achieved by torque wrench or hydraulic wrench to ensure that the bottom plate of the rack upright is rigidly fixed to the ground and resists horizontal shearing force.

[0004] However, while adjustable anchor bolts and anti-loosening locking schemes can achieve rigid fixation, they rely on thread friction and preload to maintain locking. Under heavy load dynamic impact or long-term vibration conditions, thread loosening and preload attenuation are prone to occur. Furthermore, they lack adaptive compensation capabilities and cannot utilize the wedge-face squeezing effect under heavy load to automatically eliminate fit clearances and increase frictional resistance as the load increases. Therefore, when the bolt preload decreases due to creep or fretting wear, slight separation may occur between the base plate and the embedded steel plate, resulting in a sharp reduction in horizontal shear resistance. At the same time, external tools such as torque wrenches are required to periodically retighten the bolts, resulting in high maintenance costs and difficulty in responding to sudden off-center loads in real time.

[0005] Although the above problems can be solved, the overall stability is poor when no goods are placed on it. It cannot perform the corresponding stable guiding operation when locking by gravity. It is prone to impact-induced movement or jamming and deflection. Not only can it not complete the self-locking action smoothly, but it may also cause additional bending moment and local stress concentration in the column base plate due to uneven displacement of the wedge blocks. This will aggravate the accumulation of initial installation errors of the entire structure and reduce the reliability and safety of the equipment in long-term operation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a heavy-duty anti-deviation intelligent warehouse rack locking mechanism, which has the advantages of automatically locking using its own weight and not being able to guide downward movement during automatic locking, thus solving the problems mentioned in the background technology.

[0007] The present invention provides the following technical solution: a heavy-duty anti-deviation intelligent warehouse rack locking mechanical structure, including a ground and a base plate, wherein the upper surface of the ground and the lower surface of the base plate are disposed therebetween, and the ground and the base plate are not in direct contact, a pre-embedded block is fixedly installed inside the ground, the pre-embedded block has a bottom groove inside, the top inner wall of the pre-embedded block has a top groove, and the pre-embedded block is provided with a downward locking mechanism that converts the heavy-duty downward pressure into locking force; The power output end of the pressing locking mechanism is equipped with a guide mechanism that converts the downward pressure into a guiding sliding force. The pressing locking mechanism ensures the stability of the whole when placed by the action of heavy load force, and avoids the occurrence of displacement.

[0008] Preferably, the pressing and locking mechanism includes a connecting frame, a top wedge, a limiting rod, a side wedge, a connecting spring, and a telescopic rod. The upper surface of the connecting frame is fixedly installed on the upper surface of the base plate, and the upper surface of the top wedge is fixedly installed on the lower surface of the connecting frame. A rectangular groove is provided on the left side of the interior of the embedded block. Both ends of the limiting rod are fixedly installed on the inner walls of the rectangular groove. The bottom inner wall of the side wedge is slidably connected to the outer surface of the limiting rod. One end of the connecting spring is fixedly installed on the left side of the interior of the embedded block. One side of the telescopic rod is fixedly installed on the left side of the interior of the embedded block. The upper width of the top wedge is the same as the opening size of the top groove, and after installation, the upper side of the top wedge is parallel to the upper surface of the embedded block.

[0009] Preferably, the guiding mechanism includes a guide rod, the guide rod is fixedly installed on the lower surface of the base plate, the interior of the embedded block is provided with a guide groove, and the inner wall of the guide groove is slidably connected to the outer surface of the guide rod.

[0010] Preferably, one end of the connecting spring is fixedly installed to the left side of the side wedge block, and one side of the telescopic rod is fixedly installed to the left side of the side wedge block.

[0011] Preferably, a rectangular groove 2 is provided on the right side of the interior of the embedded block, a limiting rod 2 is fixedly installed on the inner wall of the rectangular groove 2, and a side wedge 2 is slidably connected to the outer surface of the limiting rod 2.

[0012] Preferably, a connecting spring is fixedly installed on the right side of the second side wedge block, and a telescopic rod is fixedly installed on the right side of the second side wedge block. One end of both the connecting spring and the telescopic rod is fixedly installed inside the right side of the pre-embedded block.

[0013] Preferably, a pulling frame is fixedly installed on the left side of the rectangular groove 2, the outer surface of the pulling frame 1 is slidably connected to the inner wall of the embedded block, and a pulling block 1 is fixedly installed on the left end of the pulling frame 1.

[0014] Preferably, a second pulling frame is fixedly installed on the right side of the second limiting rod, and a second pulling block is fixedly installed on the right end of the second pulling frame.

[0015] Preferably, after the top wedge moves down, it fits against the opposite sides of the first side wedge and the second limiting rod, forcing the first side wedge and the second limiting rod to move to both sides. When the top wedge continues to move down, it enters the interior of the bottom groove, and the first side wedge and the second limiting rod rebound. The opposite sides of the second rectangular groove and the second limiting rod abut against the two sides of the connecting frame, locking the whole.

[0016] Preferably, a connecting block is fixedly installed on the upper surface of the base plate, and columns are fixedly installed on all four sides of the upper surface of the connecting block. Multiple trays are fixedly installed on one side of each of the four sets of columns, and a top cover is fixedly installed on the top of each of the four sets of columns. A screw is installed in the internal thread of the base plate, and an installation groove is opened in the interior of the ground. A hand-tightening bolt is threaded on the outer surface of the screw. After the entire installation is completed, the lower surface of the hand-tightening bolt abuts against the upper surface of the base plate, and the outer surface of the screw is connected to the interior of the installation groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This heavy-duty anti-deviation intelligent warehouse rack locking mechanism, through the setting of a downward locking mechanism, includes a connecting frame, a top wedge, a limit rod, a side wedge, a connecting spring, and a telescopic rod, and cooperates with the top groove, bottom groove, rectangular groove one, and rectangular groove two structures inside the pre-embedded block. This solves the defects of existing adjustable anchor bolts that rely on thread friction and preload to maintain locking, and experience thread loosening and preload attenuation under heavy-duty dynamic impact. When heavy-duty goods are placed on the pallet, gravity is transmitted to the base plate through the uprights and connecting blocks, driving the top wedge to press vertically downwards, with its two inclined surfaces interacting with the side wedges. The inclined surfaces of the first and second side wedges generate a wedge-shaped clamping effect, automatically converting the vertical load into a horizontal locking force. This forces the two sides to give way and then locks them onto the sides of the connecting frame under the rebound action. This achieves an adaptive compensation mechanism where the greater the load, the stronger the locking force. It avoids slight separation between the base plate and the embedded block due to bolt creep or fretting wear, thus ensuring that the horizontal shear resistance does not decrease over time. At the same time, it eliminates the need to rely on external tools such as torque wrenches for regular re-tightening, reducing maintenance costs. It can also respond to sudden off-center load impacts in real time, improving the long-term operational reliability and safety of the rack under heavy load conditions.

[0018] 2. This heavy-duty anti-deviation intelligent warehouse racking locking mechanism, through the setting of a guiding mechanism, including guide rods and guide grooves, ensures that the base plate always slides along the precise vertical path of the guide rods and guide grooves during heavy-load pressing or unloaded lifting. This effectively overcomes the shortcomings of existing wedge self-locking structures, such as poor stability under no-load conditions and lack of stable guidance during instantaneous gravity loading, which can easily lead to impact-induced movement or jamming. Under no-load conditions, the sliding cooperation of the guide rods and guide grooves maintains the base plate and top wedge in a definite vertical posture, preventing free swaying due to the lack of gravity constraint and ensuring that the bottom of the racking upright always has a stable initial positioning. During heavy-load loading, the guiding mechanism ensures that the top wedge enters the top and bottom grooves with a smooth vertical trajectory, preventing additional bending moments and local stress concentrations in the upright base plate caused by uneven wedge displacement. Simultaneously, the auxiliary pre-tightening of the screw and mounting groove, along with the locking operation of the hand-tightened bolts, makes the overall locking action smooth, precise, and repeatable, eliminating the risk of accumulated initial installation errors.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 , Figure 4 and Figure 5 A heavy-duty anti-deviation intelligent warehouse rack locking mechanical structure includes a ground 1 and a base plate 2. The upper surface of the ground 1 and the lower surface of the base plate 2 are disposed between them, and the ground 1 and the base plate 2 are not in direct contact. A pre-embedded block 7 is fixedly installed inside the ground 1. A bottom groove 11 is opened inside the pre-embedded block 7. A top groove 10 is opened on the inner wall of the top of the pre-embedded block 7. A downward locking mechanism that converts heavy-duty downward pressure into locking force is provided inside the pre-embedded block 7. The power output end of the downward locking mechanism is equipped with a guide mechanism that converts the downward pressure into a guiding sliding force. The downward locking mechanism ensures the overall stability during placement through the action of heavy load, preventing deviation. The downward locking mechanism includes a connecting frame 8, a top wedge 9, a limiting rod 13, a side wedge 14, a connecting spring 15, and a telescopic rod 16. The upper surface of the connecting frame 8 is fixedly installed with the upper surface of the base plate 2, and the upper surface of the top wedge 9 is fixedly installed with the lower surface of the connecting frame 8. A rectangular groove 12 is opened on the left side inside the embedded block 7. Both ends of the limiting rod 13 are connected to... The inner walls of rectangular groove 12 are fixedly installed on both sides. The bottom inner wall of side wedge block 14 is slidably connected to the outer surface of limit rod 13. One end of connecting spring 15 is fixedly installed to the left side inside embedded block 7. One side of telescopic rod 16 is fixedly installed to the left side inside embedded block 7. The upper width of top wedge block 9 is the same as the opening size of top groove 10, and after installation, the upper side of top wedge block 9 is parallel to the upper surface of embedded block 7. One end of connecting spring 15 is fixedly installed to the left side of side wedge block 14, and one side of telescopic rod 16 is fixed to the left side of side wedge block 14. The embedded block 7 is fixedly installed with a rectangular groove 24 on its right side. A limit rod 25 is fixedly installed on the inner wall of the rectangular groove 24. A side wedge 26 is slidably connected to the outer surface of the limit rod 25. A connecting spring 27 is fixedly installed on the right side of the side wedge 26, and a telescopic rod 28 is fixedly installed on the right side of the side wedge 26. One end of both the connecting spring 27 and the telescopic rod 28 is fixedly installed to the right side of the embedded block 7. A pulling frame 17 is fixedly installed on the left side of the rectangular groove 24. The outer surface of the pulling frame 17 is slidably connected to the inner wall of the embedded block 7. A pull block 18 is fixedly installed on the left end of the first 17, and a pull frame 29 is fixedly installed on the right side of the second limit rod 25. A pull block 30 is fixedly installed on the right end of the pull frame 29. After the top wedge 9 moves down, it fits against the opposite sides of the side wedge 14 and the second limit rod 25, forcing the side wedge 14 and the second limit rod 25 to move to both sides. When the top wedge 9 continues to move down, it enters the interior of the bottom groove 11, and the side wedge 14 and the second limit rod 25 rebound. The opposite sides of the rectangular groove 24 and the second limit rod 25 abut against the two sides of the connecting frame 8, locking the whole.

[0023] Specifically, the downward pressure from the heavy load on the rack drives the top wedge 9 to move downwards. The wedge surface then converts this downward pressure into a lateral thrust from the side wedge 14 and the limiting rod 25. No external power source is required; it automatically locks after installation. No manual intervention or power supply is needed during operation. After the top wedge 9 moves downwards, it simultaneously presses the side wedge 14 and the limiting rod 25 to both sides. These slide along the limiting rod 13 and the limiting rod 25 within the rectangular grooves 12 and 24. Ultimately, the side wedge 14 and the inner wall of the rectangular groove 24, and the limiting rod 25 and the two sides of the connecting frame 8, form opposing contact, achieving bidirectional mechanical locking and effectively preventing the rack from shifting under heavy loads or lateral forces. The connecting spring 15, telescopic rod 16, connecting spring 27, and telescopic rod 28 provide reset preload for side wedge block 14 and side wedge block 26, respectively. When disassembly is required, the side wedge blocks can be retracted by pulling the pulling frame 17 by pulling the pulling block 18 and pulling the pulling frame 29 by pulling the pulling block 30. The top wedge block 9 can then smoothly exit the bottom groove 11, achieving quick unlocking and facilitating the relocation or rearrangement of the shelving. The left limit rod 13 and side wedge block 14 are symmetrically arranged with the right limit rod 25 and side wedge block 26. The connecting spring 15 and connecting spring 27, and the telescopic rod 16 and telescopic rod 28 correspond one-to-one to ensure that both sides move synchronously when pressed down to lock, avoiding the problem of uneven load caused by unilateral force.

[0024] Please see Figure 1 , Figure 6 and Figure 7 The guiding mechanism includes a guide rod 19, which is fixedly installed on the lower surface of the base plate 2. A guide groove 20 is provided inside the pre-embedded block 7, and the inner wall of the guide groove 20 is slidably connected to the outer surface of the guide rod 19.

[0025] Specifically, the guide rod 19 slides into the guide groove 20, restricting the bottom plate 2 to move only in the vertical direction during the pressing process. This prevents the bottom plate 2 from tilting due to uneven force distribution, ensuring that the top wedge 9 accurately aligns into the top groove 10 and bottom groove 11. Consequently, the side wedges 14 and 26 are simultaneously subjected to force, preventing uneven locking caused by initial contact on one side. The guide rod 19 bears all the lateral force when the bottom plate 2 is pressed down, so that the contact surface between the top wedge block 9 and the top groove 10 and the bottom groove 11 only bears the positive pressure in the vertical direction, reducing the friction and lateral scraping between the wedge surfaces, and reducing the wear rate of the embedded block 7 and the connecting frame 8.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4A connecting block 3 is fixedly installed on the upper surface of the base plate 2. Columns 4 are fixedly installed around the upper surface of the connecting block 3. Multiple trays 5 are fixedly installed on one side of each of the four sets of columns 4. A top cover 6 is fixedly installed on the top of each of the four sets of columns 4. A screw 21 is installed inside the base plate 2. An installation groove 23 is opened inside the ground 1. A hand-tightening bolt 22 is threaded onto the outer surface of the screw 21. After the entire installation is completed, the lower surface of the hand-tightening bolt 22 abuts against the upper surface of the base plate 2, and the outer surface of the screw 21 is connected to the interior of the installation groove 23.

[0027] Specifically, the screw 21 inside the base plate 2, in conjunction with the hand-tightening bolt 22 in the mounting groove 23 of the ground 1, automatically locks the base plate after the locking mechanism is pressed down. Then, the hand-tightening bolt 22 is tightened manually to achieve a dual fixation of gravity self-locking and mechanical anchoring. This is especially suitable for anti-tipping and anti-pull-out in heavy-load scenarios. The hand-tightening bolt 22 can be manually tightened without tools. When the shelf needs to be moved or rearranged, the bottom anchor can be released by loosening the hand-tightening bolt 22. With the help of the pull block 18 and pull block 20 to unlock the locking mechanism, disassembly can be completed quickly without destructive construction.

[0028] Working principle: When the shelf is not in use, the base plate 2 slides with the guide groove 20 inside the pre-embedded block 7 via the guide rod 19, maintaining initial vertical positioning. At this time, the top wedge 9 is located above the top groove 10. The side wedges 14 and 26 are held in their initial retracted positions within the rectangular grooves 12 and 24 by the elastic action of the connecting spring 15, telescopic rod 16, connecting spring 27, and telescopic rod 28, respectively, and do not contact the top wedge 9. At the same time, the screw 21 passes through the base plate 2 but does not screw into the mounting groove 23 in the ground 1. The hand-tightened bolt 22 only lightly touches the upper surface of the base plate 2 to provide auxiliary pre-tightening, but the overall locking force has not yet been established. When goods are placed... On the tray 5, gravity is transmitted to the base plate 2 through the column 4 and connecting block 3. The base plate 2 slides vertically downward smoothly along the constraints of the guide rod 19 and guide groove 20, ensuring that the top wedge 9 enters the top groove 10 of the embedded block 7 in a precise vertical posture, avoiding impact-induced movement or jamming and tilting. At the same time, the connecting frame 8 moves downward, driving the top wedge 9 deeper into the embedded block 7. The top wedge 9 continues to move downward, and its two inclined surfaces first contact the opposite inclined surfaces of the side wedge 14 and the side wedge 26. Using the wedge surface squeezing effect, the vertical downward pressure of the top wedge 9 is decomposed into a horizontal thrust, forcing the side wedge 14 to slide to the left along the limiting rod 13 and compress the connecting spring 15 and the telescopic rod 16, and the side wedge 26... Slide the limit rod 25 to the right and compress the connecting spring 27 and the telescopic rod 28 to allow the wedges on both sides to clear the passage; when the top wedge 9 is fully inserted into the bottom groove 11, its top width is flush with the upper surface of the embedded block 7. At this time, the compressed connecting spring 15 and connecting spring 27 rebound, pushing the side wedge 14 and side wedge 26 to reset towards each other, so that the inner walls of the opposite sides of the two wedges abut against the outer walls of both sides of the connecting frame 8, forming a mechanical self-locking, and rigidly locking the bottom plate 2 and the embedded block 7 into one piece. The greater the load, the stronger the wedge surface clamping force, which adaptively eliminates the fit gap and greatly enhances the resistance to horizontal shearing. After locking, tighten the hand-tightened bolt 22 manually or with a tool, so that the screw 21 is in place. Tensioning within the loading slot 23 provides additional pre-tensioning force, while the sensor network monitors verticality and displacement signals in real time, forming a closed-loop monitoring system. When the goods are removed, gravity disappears, and the pulling frame 17 and pulling frame 29 can be manually or electrically pulled outwards via pulling block 18 and pulling block 20 to overcome the elasticity of connecting spring 15 and connecting spring 27, causing side wedge block 14 and side wedge block 26 to retract back into rectangular slot 12 and rectangular slot 24, releasing the locking of the connecting frame 8. Subsequently, the bottom plate 2 rises smoothly and resets under the guidance of guide rod 19 and guide slot 20, and the top wedge block 9 exits the bottom slot 11, restoring the entire system to its initial unloaded standby state, ready for the next heavy-load operation.

[0029] The embedded block 7, serving as the core load-bearing base, must be integrally cast from high-strength ductile iron or cast steel and undergo annealing to eliminate internal stress, ensuring the dimensional accuracy and impact toughness of the top groove 10, bottom groove 11, rectangular groove one 12, rectangular groove two 24, and guide groove 20. Its surface must be carburized or high-frequency quenched to enhance the wear resistance of the contact surfaces with the top wedge block 9, side wedge block one 14, side wedge block two 26, and guide rod 19. The wedge surfaces of the top wedge block 9, side wedge block one 14, and side wedge block two 26 should be made of alloy tool steel, and additional cutting should be performed at the wedge surfaces. Oil reservoirs or molybdenum disulfide solid lubricant coatings should be provided to prevent adhesive wear or scratches caused by frequent heavy-load compression. Connecting springs 15 and 27 should be made of fatigue-resistant silicon manganese steel and reinforced by shot peening. Telescopic rods 16 and 28 should use chrome-plated piston rods with copper-based guide sleeves to prevent jamming due to rust or dust intrusion during long-term use. Load-bearing structural components such as columns 4 and trays 5 should be cold-formed from high-strength low-alloy steel, and all welds should be subjected to ultrasonic testing. Screw 21 should be made of 40Cr material.

[0030] During the initial installation phase, a laser alignment instrument must be used to calibrate the concentricity of the embedded block 7 and the base plate 2 to ensure the clearance control between the guide rod 19 and the guide groove 20. Too small a clearance will cause sliding resistance, while too large a clearance will weaken the guiding accuracy. After installation, a no-load lifting test should be performed to check whether the top wedge 9 can smoothly enter the top groove 10 and fully settle into the bottom groove 11, and whether the side wedges 14 and 26, under the push of the connecting springs 15 and 27, synchronously rebound and lock onto both sides of the connecting frame 8. If asynchronous rebound or jamming is found, it is necessary to check whether there are foreign objects or burrs in the rectangular grooves 12 and 24. During daily use, the fatigue condition of the connecting springs 15 and 27 and the wear condition of the wedge surfaces of the side wedges 14 and 26 should be checked regularly. Simultaneously, the guide rod 19 and the guide groove 20 should be kept clean. Clean and regularly add extreme pressure grease to prevent dust or metal shavings from scratching the sliding surface and affecting the smoothness of the guide. In addition, it is strictly forbidden to overtighten the hand-tightening bolt 22 when no goods are placed on it, so as not to cause excessive extra preload on the screw 21, so as not to cause elastic deformation of the embedded block 7 or the base plate 2, affecting the normal stroke of the wedge self-locking mechanism. If it is necessary to unlock after unloading the goods, the operation should be carried out in the following order: first, pull the side wedge block 14 and the side wedge block 26 outward by using the pull frame 17 and the pull frame 29 in conjunction with the pull block 18 and the pull block 20, and then lift the base plate 2. It is strictly forbidden to forcibly lift the column 4 to avoid damaging the guide rod 19 or causing the top wedge block 9 to get stuck in the bottom groove 11. At the same time, it is necessary to use the sensor network to monitor the verticality and displacement data of the rack in real time. Once abnormal deviation or stress exceeding the limit is found, the operation should be stopped immediately and a comprehensive inspection should be carried out.
