Description

Technical Field

[0001] This utility model relates to the field of cantilever rack technology, and in particular to anti-tipping components for cantilever racks. Background Technology

[0002] In modern warehousing and logistics and industrial production, cantilever racks, as a type of storage equipment specifically designed for long, cylindrical, and sheet-like goods, are widely used in various fields such as the building materials industry (e.g., pipe and profile storage), the timber processing industry (e.g., log and plank stacking), and the machinery manufacturing industry (e.g., large shaft and rod parts storage) due to their advantages of high space utilization, convenient goods access, and strong load-bearing capacity adaptability. Their structure mainly consists of uprights, cantilever beams, a base, and connectors. The cantilever beams are arranged in layers along the height of the uprights, and the spacing can be flexibly adjusted according to the specifications of the goods. The base serves as the supporting foundation and must ensure the overall stability of the rack. Some cantilever racks are also equipped with reinforcing ribs to further enhance structural strength and meet the storage needs of goods of different weights.

[0003] As a key supporting structure to ensure the safe use of cantilever racks, the current mainstream solutions in the industry to address the risk of tipping over cantilever racks are to add support structures or counterweights to the bottom of the rack to improve the overall anti-tipping capacity of the rack and meet the basic safety requirements when the cantilever rack is carrying heavy goods. However, these solutions have significant shortcomings in terms of structural flexibility and spatial adaptability, making it difficult to adapt to the diverse usage needs in modern warehousing scenarios.

[0004] Most existing anti-tipping solutions for cantilever racks adopt a structure in which fixed support plates are welded to both sides of the base. The support area is fixed, which has limitations and cannot flexibly adjust the support range according to changes in the weight of the goods. When the rack is carrying lighter goods and no additional anti-tipping support is needed, the fixed support plates still occupy extra space, which increases the overall footprint of the rack, squeezes the storage operation aisle, and reduces the utilization rate of storage space. At the same time, the protruding support plates can cause inconvenience to the workers in handling the goods. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cantilever rack anti-tipping component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cantilever rack anti-tipping component, comprising two base plates, each base plate having a column fixedly installed at the upper center, and a rectangular groove extending through the sides of both base plates, with a rack plate installed inside the rectangular groove, teeth on both sides of the rack plate, an adjusting screw rotatably installed on one end of the rack plate, and the other end of the adjusting screw extending through to the outside of the base plate and fixedly connected to a crank handle;

[0007] Three concave plates are symmetrically fixedly installed on both sides of the base plate. I-shaped rods are hinged to the inner side of each concave plate. The upper end of each I-shaped rod passes through the concave plate and is fixedly installed with a linkage gear. The side parts of the multiple linkage gears mesh with the side parts of the rack plate respectively. A support plate is fixedly installed on the side part of each I-shaped rod.

[0008] Preferably, the rectangular groove has guide rails at both the upper and lower ends, and the rack plate has slide bars that are adapted to the guide rails at both the upper and lower ends. The rack plate is slidably installed on the inner side of the guide rails through the slide bars, and the through connection between the adjusting screw and the base plate is a threaded connection.

[0009] Preferably, the inner side of the support plate is provided with a groove, the inside of the groove is provided with a stop block, and the bottom of the stop block is provided with multiple anti-slip textures.

[0010] Preferably, a threaded rod is rotatably mounted on the upper end of the abutment block, the upper end of the threaded rod extends through to the outer side of the upper end of the support plate and is fixedly mounted with a handwheel, and the through connection between the threaded rod and the support plate is a threaded connection.

[0011] Preferably, the inner wall of the groove is symmetrically provided with limiting slide rails at both ends, and the two ends of the abutment are fixedly installed with sliders. The abutment is slidably installed on the inner side of the limiting slide rails through the sliders.

[0012] Preferably, the length of the rack plate is less than the inner length of the rectangular groove, and when the adjusting screw is rotated to the outer limit position of the base plate, the sides of the multiple support plates are in contact with the two sides of the base plate.

[0013] Preferably, when the adjusting screw rotates and drives the rack plate to move to the extreme position away from the crank handle, at this time the plurality of support plates rotate 90° around the axis of the I-shaped rod to the unfolded state.

[0014] Preferably, multiple support arms are detachably connected to both sides of the column by fixing bolts, and two connecting rods are detachably connected to the corresponding surfaces of two columns by bolts.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model features multiple sets of foldable support plates on both sides of the base plate. Turning the crank causes the adjusting screw to rotate, allowing the rack plate to slide along the guide rail in the rectangular groove. This, in turn, drives the I-beam rod to rotate the support plate around the hinge point via gear meshing. When the rack plate moves to its limit position away from the crank, the support plate unfolds 90° to expand the support area and enhance the anti-tipping ability of the shelf. When the rack plate moves to its limit position towards the crank, the support plate retracts into contact with the base plate, achieving flexible adjustment of the anti-tipping support area. This ensures the stability of the shelf under heavy loads, reduces space occupation during light loads or when idle, improves the utilization rate of storage space, and avoids the risk of tripping due to protruding support plates, ensuring operational safety.

[0017] 2. This utility model features a stop block on the support plate, with anti-slip texture on the bottom of the stop block. The upper end is connected to a threaded rod and a handwheel. Rotating the handwheel drives the threaded rod to rotate, causing the stop block to move up and down along the limiting slide rail. The length of the stop block extending out of the groove is adjusted until the anti-slip texture on the bottom of the stop block is in close contact with the ground. The contact state between each support plate and the ground can be adjusted individually according to the flatness of the ground or the load-bearing requirements of the shelving. The anti-slip texture enhances the friction between the stop block and the ground, further improving the anti-tipping effect of the shelving. At the same time, the independent adjustment design of each stop block allows the shelving to maintain stable support on uneven storage floors, expanding the applicable scenarios of the shelving.

[0031] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0033] Example: Reference Figures 1-5 The cantilever rack anti-tipping component includes two base plates 1. Each base plate 1 has a column 2 fixedly installed at the upper center. Both base plates 1 have rectangular grooves 3 through them. A rack plate 5 is installed inside the rectangular groove 3. The rack plate 5 has teeth on both sides. An adjusting screw 501 is rotatably installed on one end of the rack plate 5. The other end of the adjusting screw 501 extends through to the outside of the base plate 1 and is fixedly connected to a crank handle 502.

[0034] Three concave plates 4 are symmetrically fixedly installed on both sides of the base plate 1. I-shaped rods 402 are hinged to the inner side of each concave plate 4. The upper end of each I-shaped rod 402 passes through the concave plate 4 and is fixedly installed with a linkage gear 403. The side parts of the multiple linkage gears 403 mesh with the side parts of the rack plate 5 respectively. A support plate 401 is fixedly installed on the side of each I-shaped rod 402.

[0035] Specifically: In actual use, the adjusting screw 501 is threadedly connected to the base plate 1, which can convert the rotational force of the crank handle 502 into the driving force to push the rack plate 5 to slide. At the same time, the rack plate 5 meshes with the linkage gear 403 through the teeth on both sides, converting its own linear sliding into the rotational motion of the linkage gear 403. This can drive the I-shaped rod 402 to rotate around the hinge point on the inner side of the concave plate 4, thereby driving the support plate 401 to expand or retract synchronously. When the support plate 401 is expanded, it can greatly increase the contact support area between the base plate 1 and the ground, enhancing the anti-tipping ability of the shelf. When retracted, it fits the base plate 1, reducing space occupation.

[0036] By turning the crank handle 502, the adjusting screw 501 rotates and drives the rack plate 5 to slide along the rectangular groove 3. The rack plate 5 meshes with the linkage gear 403 through its teeth, driving the linkage gear 403 to rotate. The linkage gear 403 then drives the I-shaped rod 402 to rotate around the hinge point of the concave plate 4, ultimately realizing the unfolding or retraction of the support plate 401. The entire process can be completed without disassembling any parts to adjust the anti-tipping support structure, simplifying the operation process and ensuring the stability of the adjustment process, effectively improving the flexibility and safety performance of the cantilever rack.

[0037] The upper and lower ends of the rectangular groove 3 are provided with guide rails 503. The upper and lower ends of the rack plate 5 are fixedly installed with slide bars 504 that are compatible with the guide rails 503. The rack plate 5 is slidably installed on the inner side of the guide rail 503 through the slide bars 504. The setting of the guide rail 503 provides a precise guiding path for the slide bars 504 of the rack plate 5, ensuring that the rack plate 5 always moves in the preset direction when sliding, avoiding lateral deviation or jamming. The through connection between the adjusting screw 501 and the base plate 1 is a threaded connection. When the crank handle 502 is turned to drive the adjusting screw 501 to rotate, the axial force generated by the threaded engagement can smoothly push the rack plate 5 to move along the guide rail 503.

[0038] The inner side of the support plate 401 is provided with a groove 6, and the inside of the groove 6 is provided with a stop block 601. The bottom of the stop block 601 is provided with multiple anti-slip textures 602. A threaded rod 603 is rotatably installed on the upper end of the stop block 601. The upper end of the threaded rod 603 extends through to the outer side of the upper end of the support plate 401 and is fixedly installed with a handwheel 604. The threaded rod 603 and the support plate 401 are connected by a thread. The inner wall of the groove 6 is symmetrically provided with limit slide rails 701 at both ends. The two ends of the stop block 601 are fixedly installed with sliders 7. The stop block 601 is slidably installed on the inner side of the limit slide rails 701 through the sliders 7.

[0039] Specifically: In actual use, the setting of the abutment block 601 can enhance the support stability by contacting the ground, and its bottom anti-slip texture 602 can increase the friction with the ground, reduce the risk of slippage during support, and further improve the anti-tipping effect. At the same time, the threaded rod 603 is threadedly connected to the support plate 401, which can convert the rotational force of the handwheel 604 into the driving force to push the abutment block 601 up and down.

[0040] After the support plate 401 is unfolded, if the warehouse floor is uneven, the operator holds the handwheel 604 and applies rotational force. The handwheel 604 drives the threaded rod 603 to rotate synchronously. The threaded rod 603 drives the abutment 601 to move up and down along the guide structure formed by the limit slide rail 701 and the slider 7 through the threaded engagement until the bottom of the abutment 601 is in close contact with the ground. If there are local bumps or depressions in the ground, the height of the abutment 601 can be adjusted individually for the corresponding support plate 401 to ensure that each support plate 401 can form effective support with the ground. There is no need to adjust the entire rack, which simplifies the ground adaptation operation. At the same time, the anti-slip texture 602 enhances the adhesion to the ground and further improves the overall anti-tipping stability of the rack.

[0041] The length of the rack plate 5 is less than the inner length of the rectangular groove 3. When the adjusting screw 501 is rotated to the outer limit position of the base plate 1, the sides of the multiple support plates 401 are made to fit against the two sides of the base plate 1, allowing the support plates 401 to be completely stored when not in use, reducing space occupation and eliminating the risk of people tripping. When the adjusting screw 501 is rotated and drives the rack plate 5 to move away from the crank handle 502 to the limit position, the multiple support plates 401 rotate 90° around the axis of the I-shaped rod 402 to the unfolded state, and the two sides of the column 2 are fixed. The support arms 201 are detachably connected by fixed bolts. The support arms 201 on both sides of the upright 2 are detachably connected by fixed bolts, which makes it easy to adjust the number and spacing of the support arms 201 according to the specifications of the goods, adapt to the storage needs of goods of different lengths and heights, and improve the versatility of the rack. The corresponding surfaces of the two uprights 2 are detachably connected by bolts with two connecting rods 202. The setting of connecting rods 202 can enhance the connection rigidity between the uprights 2, so that the two uprights 2 form a stable whole. Combined with the bottom anti-tipping structure, it further improves the overall stability of the rack.

[0042] The working principle of this utility model is as follows: In specific use, firstly, based on the weight and specifications of the goods to be stored on the cantilever rack, determine whether the anti-tipping support structure needs to be deployed. If the weight of the goods is large and there is a risk of tipping, the operator first rotates the handle 502 on the outer side of the base plate 1. The handle 502 drives the adjusting screw 501 to rotate. Since the adjusting screw 501 is threadedly connected to the base plate 1, and the rack plate 5 slides and adapts to the guide rail 503 inside the rectangular groove 3 through the upper and lower end slide bars 504, the rotation of the adjusting screw 501 will drive the rack plate 5 to move away from the handle along the rectangular groove 3. 502 slides smoothly on one side; during the sliding process of the rack plate 5, the teeth on both sides of the rack plate 5 mesh with the linkage gear 403 at the top of the I-shaped rod 402 on both sides of the concave plate 4 of the base plate 1. The gear transmission causes the I-shaped rod 402 to rotate synchronously around the hinge point on the inner side of the concave plate 4 until the rack plate 5 moves to the limit position of the rectangular groove 3 away from the crank handle 502. At this time, the I-shaped rod 402 drives the side support plate 401 to rotate 90° around the axis and be in a horizontal unfolded state, which greatly expands the support contact area between the base plate 1 and the ground, providing stable anti-tipping support for the rack.

[0043] After the support plate 401 is unfolded, if the storage floor is uneven, the operator can rotate the upper handwheel 604 individually for each support plate 401. The handwheel 604 drives the threaded rod 603 to rotate. The threaded rod 603 is threadedly connected to the support plate 401 at the through-hole. The abutment 601 slides with the limiting slide rail 701 on the inner wall of the groove 6 through the sliders 7 at both ends. The rotation of the threaded rod 603 will drive the abutment 601 to move vertically downward along the limiting slide rail 701 until the anti-slip texture 602 at the bottom of the abutment 601 touches the ground. The support plates 401 are tightly fitted, and the height of each abutment 601 is adjusted to ensure that each support plate 401 can make effective contact with the ground, avoiding some support points from being suspended due to uneven ground, and further enhancing the stability of the support. If the weight of the goods is reduced or the shelf needs to be moved, the crank handle 502 is turned in the opposite direction, so that the rack plate 5 slides towards the side closer to the crank handle 502. Through the reverse transmission of the gear, the I-shaped rod 402 is driven to reset with the support plate 401 until the side of the support plate 401 is completely fitted with both sides of the bottom plate 1, thus completing the storage of the support structure.

[0044] Meanwhile, during the overall assembly and use of the rack, the support arms 201 can be detachably installed at preset positions on both sides of the uprights 2 by fixing bolts according to the length and height requirements of the goods. The spacing of the support arms 201 can be flexibly adjusted to accommodate the storage of goods of different specifications. Then, the connecting rods 202 on the corresponding sides of the two uprights 2 are fixed with bolts to enhance the connection rigidity between the two uprights 2, so that the rack body and the bottom anti-tipping structure form a coordinated support, further improving the overall structural stability of the cantilever rack when carrying goods, and ensuring the safe and orderly operation of warehousing.
