Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leveling structure technology, specifically relating to a leveling structure for a storage rack. Background Technology
[0002] Leveling is widely used in daily production and life. Taking mechanical equipment as an example, leveling structures are used to adjust the force relationship between workpieces, thereby ensuring the overall relative balance and stability. Leveling is especially important for large machine frames (such as storage racks).
[0003] For example, patent (CN117184731A) discloses a horizontal multi-layer intelligent scroll storage, which includes sprocket drive assemblies located on both sides of the frame. The sprocket drive assembly includes a drive chain and sprockets. The drive chain is bent in multiple ways, and multiple sprockets mesh with the drive chain. The two ends of the connecting shaft are fixedly connected to the drive chains in the two sprocket drive assemblies respectively. The connecting shaft is provided with two hooks, and items are suspended on the hooks to realize the transfer and storage of items.
[0004] As can be seen from the above, the lack of a leveling structure in the rack may cause the entire reel storage to be in a non-level state. On the one hand, being in a non-level state for a long time may cause deformation of the rack structure. Especially for heavy equipment, uneven load distribution will accelerate metal fatigue, reduce the overall load-bearing capacity and safety of the rack. Moreover, the deformation of the rack will cause meshing deviation and misalignment between the transmission chain and sprocket, resulting in jamming and wear, affecting the normal operation of the entire transmission component. On the other hand, the tilt of the rack can easily cause items to slide along the tilt angle during storage, thereby detaching from the hook and falling, posing a threat to other equipment or personnel in the vicinity. Summary of the Invention
[0005] In view of this, the purpose of this utility model is to provide a leveling structure for storage racks to solve the technical problem that the lack of a leveling structure in the racks in the prior art causes the suspended objects to fall off easily.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A leveling structure for a storage rack includes a frame and a rotating system mounted on both sides of the frame. The rotating system includes multiple sprockets distributed on the sides of the frame and a transmission chain meshing with the sprockets. The transmission chain has multiple bends. Each sprocket includes guide wheels at its four apex and multiple steering wheels distributed at different heights inside. Connecting rods are provided between the transmission chains, and multiple connecting rods are evenly distributed on the transmission chains. At least two hooks are rotatably connected to the connecting rods. The frame has a square frame structure. A leveling structure is provided at the bottom of the frame. The leveling structure includes an adjusting rod. A clamping part is provided in the middle of the adjusting rod. A threaded section is formed above the clamping part. A lifting plate is threadedly connected to the threaded section. The upper end of the threaded section passes vertically through the bottom surface of the frame and extends into the interior of the frame. The lifting plate abuts against the bottom surface of the frame to support the frame. A grounding section is located below the clamping part, and a pad is provided between the grounding section and the ground.
[0008] Furthermore, the frame includes two opposing rectangular uprights, the interior of which is hollow, and the uprights are connected and fixed together by crossbars;
[0009] Furthermore, the outer surface of the clamping part includes at least a pair of clamping surfaces located on opposite sides and both being vertical planes;
[0010] Furthermore, the clamping part is shaped like a regular hexagonal prism;
[0011] Furthermore, the grounding section is cylindrical, with its bottom end uniformly contracting from top to bottom and from the outside to the inside to form a circular grounding surface, which makes smooth contact with the pad.
[0012] Furthermore, a pair of casters are provided on the bottom surface of the frame. The casters are located inside the leveling structure and close to it, which enhances the flexibility of the entire storage rack.
[0013] The beneficial effects of this utility model are as follows:
[0014] Compared with existing technologies, the leveling structure ensures that the storage rack is in a horizontal state. On the one hand, it can prevent the rack structure from deforming due to tilting during operation, thus ensuring the overall safety and reliability. It can also prevent wear between parts and extend the service life of the entire equipment. On the other hand, it can prevent items from becoming detached during storage, thus preventing them from threatening surrounding equipment or personnel. Attached Figure Description

[0021] The following labels are shown in the attached diagram:
[0022] Frame 1, upright frame 11, crossbar 12, support plate 13, slewing system 2, sprocket 21, guide wheel 211, steering wheel 212, transmission chain 22, connecting rod 3, hook 31, leveling structure 4, adjusting rod 41, clamping part 411, threaded section 412, grounding section 413, grounding surface 414, lifting plate 42, pad 43, caster wheel 5, electronic level 6. Detailed Implementation
[0023] Example 1, specifically as follows: Figures 1-4 As shown.
[0024] A leveling structure for a storage rack includes a rack 1 and a rotating system 2 installed on both sides of the rack 1. The rack 1 has a square frame structure, and a leveling structure 4 is provided at the bottom of the rack 1. The leveling structure 4 is used to adjust the level of the entire storage rack so that the storage rack is in a horizontal and stable state.
[0025] The slewing system 2 includes multiple sprockets 21 distributed on the side of the frame 1 and a transmission chain 22 meshing with the sprockets 21, wherein the transmission chain 22 has multiple bends. The sprockets 21 are generally rectangular in shape, and each sprocket 21 includes guide wheels 211 at its four apex, with multiple steering wheels 212 distributed at different heights inside. In this embodiment, the steering wheels are distributed in a "W" shape, and the steering wheels 212 include three upper steering wheels and two lower steering wheels, wherein the lower steering wheels are at the same height as the bottom guide wheel 211, and the three upper steering wheels are at the same height and are all located below the top guide wheel 211. In this embodiment, a pair of lower steering wheels are driven to rotate by a rotary motor, thereby enabling the two sides of the slewing system 2 to operate synchronously.
[0026] Multiple support plates 13 are fixedly connected to the inner side of the frame 1 by welding. Each support plate 13 corresponds to a sprocket 21, and the two are rotatably connected by a shaft. A connecting rod 3 is provided between the two transmission chains 22. Multiple connecting rods 3 are evenly distributed on the transmission chains 22. The two ends of the connecting rods 3 are welded to the two transmission chains 22 to achieve a fixed connection between them. At least two hooks 31 are rotatably connected to the connecting rods 3, and hanging objects are placed through the hooks 31.
[0027] The frame 1 includes two opposing rectangular uprights 11. The uprights 11 are hollow inside and connected and fixed by crossbars 12. In this embodiment, crossbars 12 are provided at the apex of the inner side surface of the uprights 11 and at the lower edge of the inner side surface. Figure 1 As shown, the leveling structure 4 is located at both ends of the bottom surface of the frame 11, that is, the leveling structure 4 is distributed at the corners of the bottom of the frame 1.
[0028] Leveling structure 4 includes, for example: Figure 2 , Figure 3 The vertical adjusting rod 41 shown has a clamping part 411 in the middle. By clamping and rotating the clamping part 411, the entire adjusting rod 41 can be rotated. A threaded section 412 is formed above the clamping part 411. A lifting plate 42 is threadedly connected to the threaded section 412. The upper end of the threaded section 412 passes vertically through the bottom surface of the frame 11 and extends into the interior of the frame 11. The lifting plate 42 abuts against the bottom surface of the frame 11 to support the frame 1.
[0029] Below the clamping part 411 is the grounding section 413. A circular pad 43 is provided between the grounding section 413 and the ground. The pad 43 can not only evenly transmit the force from above to the ground, but also prevent ground moisture or other pollutants from corroding the adjusting rod 41.
[0030] The clamping part 411 is fixedly connected to the adjusting rod 41. The two can be integrally formed or welded. In this embodiment, the two are preferably integrally formed, which is beneficial to the transmission of force between them. The outer side of the clamping part 411 includes at least a pair of clamping surfaces located on opposite sides and both being vertical planes. In this embodiment, the shape of the clamping part 411 is preferably a regular hexagonal prism, which is convenient for clamping common tools such as wrenches and calipers.
[0031] like Figure 4 As shown, in this embodiment, the grounding section 413 is cylindrical, and its bottom end is rounded to form a circular grounding surface 414 that is uniformly contracted from top to bottom and from the outside to the inside. The grounding surface 414 is in smooth contact with the pad 43. The grounding surface 414 can reduce the contact area between the adjusting rod 41 and the pad 43, thereby reducing the friction experienced by the adjusting rod 41 during rotation.
[0032] A pair of casters 5 are also provided on the bottom surface of the upright frame 11. The casters 5 are located inside the leveling structure 4 and close to the leveling structure 4. The casters 5 improve the flexibility of the entire storage rack. It should be explained in detail that by rotating the adjusting rod 41 to make an upward movement, a large gap is left between the ground contact 414 and the ground, preventing the ground contact 414 from contacting the ground during the movement of the storage rack, which would hinder the movement of the storage rack and cause wear to the adjusting rod 41.
[0033] In addition, to achieve high-precision leveling, a digital display electronic level (model ACE-SP800) is also installed on frame 1. The two are magnetically connected, and the digital display electronic level can display angle values, relative measurement values, etc. in real time, which facilitates precise leveling.
[0034] In use, first move the storage rack to the predetermined area, then use a wrench or other tools to clamp the clamping part 411 and rotate it, so that the adjusting rod 41 rotates clockwise or counterclockwise, corresponding to the lifting plate 42 lowering or rising. While supporting the frame 1, adjust the height of the corner of the frame 1 from the ground, thereby achieving the leveling of the frame 1.
[0035] The leveled storage rack is horizontal, which on the one hand prevents the rack structure from deforming due to tilting during operation, ensuring overall safety and reliability, and also prevents wear between parts, extending the service life of the entire equipment; on the other hand, it prevents items from becoming detached during storage, threatening surrounding equipment or personnel.
[0036] Example 2, as Figure 5 As shown.
[0037] Unlike the previous embodiment, in this embodiment, the bottom of the frame 11 is provided with multiple leveling structures 4, including leveling structures 4 located at both ends of the frame 11 and at least one leveling structure 4 located in the middle. In this embodiment, a leveling structure 4 is added at the middle position of the bottom of the frame 11, which can not only share the load with the leveling structures 4 on both sides, but also prevent the bottom of the frame 11 from bending and deforming due to excessive weight at the top.
[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
