Description

Technical Field

[0001] This application belongs to the technical field of mechanical equipment, and particularly relates to a shelf. Background Technology

[0002] During the transportation of large items, due to the enormous size, weight, and columnar shape of large goods such as towers and monopiles, it is often difficult to secure them or they may be damaged. To address this, the industry has adopted support frames for towers or monopiles during transportation and transfer. The support frames can adjust the opening of the support surface according to the actual dimensions of the tower or monopile and the load requirements, thus adapting to the transportation requirements of products with different diameters.

[0003] In related technologies, rollers are used to support objects. The roller surface is in direct contact with the supported object, which can easily damage the roller. Furthermore, the contact between the roller and the supported object is point-to-point, resulting in unstable support. Summary of the Invention

[0004] This application aims to at least partially solve the technical problem of unstable installation of objects on current shelving units. To this end, this application provides a shelving unit.

[0005] This application provides a shelf, comprising:

[0006] The system comprises two sliding components, two supporting components, and a load-bearing component. The two supporting components are rotatably connected to the load-bearing component. Each supporting component has a central supporting surface, and each sliding component has a lateral supporting surface. The sliding components are disposed on the load-bearing component and on both sides of the supporting components.

[0007] In some embodiments, the load-bearing component has a load-bearing surface, and the angle between the lateral support surface and the load-bearing surface is greater than 0 degrees.

[0008] In some embodiments, the load-bearing component includes a base and a load-bearing portion, the load-bearing surface is located on the base, the load-bearing portion is disposed on the load-bearing surface, and is supported by the sliding component.

[0009] In some embodiments, the support assembly further includes a support leg connected to the base and located at the bottom of the base.

[0010] In some embodiments, the load-bearing component further includes a support portion disposed at the bottom of the load-bearing component and fixedly connected to the base.

[0011] In some embodiments, the sliding assembly includes a sliding support platform and a sliding support base. The sliding support platform is disposed on the load-bearing surface, and the sliding support base is movably disposed on the sliding support platform so that the sliding support base can move along the sliding support platform. The lateral support surface is located on the sliding support base.

[0012] In some embodiments, the sliding assembly further includes a guide rail disposed on the sliding support platform, and the sliding support base is slidably connected to the guide rail.

[0013] In some embodiments, the sliding assembly further includes a threaded screw drive and a drive unit. The drive unit is disposed on the sliding support platform and is connected to the sliding support seat via the threaded screw drive to drive the sliding support seat to move along the guide rail.

[0014] In some embodiments, the shelf further includes an anti-slip portion disposed on the central support surface and the central support surface.

[0015] In some embodiments, the anti-slip portion has multiple grooves spaced apart along a preset direction.

[0016] In the shelf proposed in this application embodiment, the object is supported by a support component and a sliding component. The support component and the sliding component are respectively provided with a central support surface and a side support surface. When supporting the object, the contact method is surface-to-surface contact, which increases the contact area, disperses the force, and stabilizes the supported object. In addition, the central support surface and the side support surface are provided to avoid direct contact between the support component and the sliding component and the supported object, thereby reducing damage.

[0017] The support component is rotatably connected to the load-bearing component and can adjust its opening by rotating itself to accommodate objects with different outer diameters.

[0018] The sliding components and support components are symmetrically arranged on the shelf. When supporting an object, they can jointly bear the weight applied by the supported object, thereby reducing the pressure on individual components, reducing the chance of damage, and increasing the service life of the object.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Please see Figures 1-4 This application discloses a shelf, including a sliding component 100, a load-bearing component 300 and a support component 200.

[0034] The load-bearing component 300 is the basic component of the shelf. The load-bearing component 300 is equipped with a base 320, which provides an installation foundation for the other components of the shelf. The base 320 can be made of alloy or steel. An alloy base 320 is lighter and easier to handle, while a steel base 320 is less prone to damage. The base 320 utilizes various structural components to reduce stress and increase load-bearing capacity, thereby increasing its load-bearing capacity and resistance to damage. This application does not limit the material and structural composition of the base 320.

[0035] Two sliding components 100 are located on both sides of the base 320, and are symmetrically arranged with respect to the center line of the base 320. Each sliding component 100 is provided with a sliding support platform 120, which provides an installation base for the other components within the sliding component 100. The sliding support platform 120 can be a hollow structure to reduce manufacturing costs, or it can be a solid structure to prevent damage. This embodiment does not limit the internal structure of the sliding support platform 120.

[0036] The sliding support platform 120 is also equipped with a sliding support seat 130. When supporting an object, the sliding support seat 130 can be moved on the sliding support platform 120 in advance according to the required diameter of the supported object, so that the sliding support seat 130 just contacts the supported object and supports the supported object. The sliding support seat 130 is provided with a side support surface 110. The side support surface 110 can be made of tough materials such as industrial rubber sheet, which has strong surface friction and can prevent the supported object from sliding, making the supported object stable. The industrial rubber sheet has strong overall toughness and can play a buffering role while bearing a large torque, avoiding damage to the sliding support seat 130 and extending its service life. The side support surface 110 has grooves 180 evenly distributed on its surface. Compared with the side support surface 110 without grooves 180, it can reduce manufacturing costs while supporting the same supported object, and increase the friction with the surface of the supported object, making the load-bearing more stable.

[0037] Specifically, the sliding support platform 120 is provided with a guide rail 140, which is fixedly connected to the sliding support platform 120. The sliding support platform 120 provides an installation base for the guide rail 140, and the guide rail 140 provides a moving track for the sliding support seat 130. The sliding support seat 130 moves on the guide rail 140. The guide rail 140 adopts a mechanical guide rail structure, which can withstand a large load while providing a sliding track. The guide rail 140 adopts a double guide rail structure, with the two guide rails 140 symmetrically arranged with respect to the center line of the sliding support platform 120. The double guide rail 140 structure can reduce the load on a single guide rail 140, reduce the probability of damage to the guide rail 140, and also ensure the stability of the sliding support seat 130 along the guide rail 140.

[0038] Specifically, the sliding support 130 can adopt a rectangular structure, a cylindrical structure, or other structures; this embodiment does not impose any restrictions on this. The sliding support 130 can be made of alloy material or steel. The bottom of the sliding support 130 has a recessed groove, aligned with the guide rail 140. The size of the recessed groove is larger than that of the guide rail 140 to ensure that the guide rail 140 can be embedded within it. The bottom of the sliding support 130 also has a fixing baffle located at the lower part of the two end faces of the recessed groove. The fixing baffle is fixedly connected to the lower parts of both ends of the recessed groove to ensure that the recessed groove and the guide rail 140 will not detach after the guide rail 140 is embedded in the recessed groove. The fixing baffle is located at the bottom of the sliding support 130 and connected to both ends of the recessed groove to ensure that the sliding support 130 moves along the axial direction of the guide rail 140.

[0039] Specifically, the sliding support platform 120 is also equipped with a threaded screw drive unit 150. The sliding support platform 120 has two through holes, and the two ends of the threaded screw drive unit 150 are rotatably connected to the sliding support platform 120 through the through holes. The sliding support seat 130 is fixedly connected to the threaded screw drive unit 150. When the sliding support seat 130 needs to move on the guide rail 140, the threaded screw drive unit 150 rotates, driving the sliding support seat 130 to move along the axial direction of the guide rail 140. The inner wall of the sliding support platform 120 is provided with several fixed panels. In this embodiment, the number of fixed panels is not limited. The threaded screw drive unit 150 is connected to the fixed panels to ensure that when the support frame bears a large load, it provides a large support force to the threaded screw drive unit 150, avoiding bending or breakage of the rod. Conversely, the threaded screw drive unit 150 can also be set on the side and bottom of the sliding support seat 130, etc. In this embodiment, the setting position of the threaded screw drive unit 150 is not limited.

[0040] Specifically, the threaded screw transmission unit 150 also includes a drive unit 160, which is fixedly connected to the threaded screw transmission unit 150. The drive unit 160 can be located at any position of the threaded screw transmission unit 150, and there is no limitation on the position of the threaded screw transmission unit 150. The drive unit 160 can adopt any driving method, such as hydraulic motor drive, servo motor drive, etc. In this embodiment, there is no limitation on the type of drive unit 160. The threaded screw transmission unit 150 is fixedly connected to the sliding support seat 130. When the sliding support seat 130 moves along the guide rail 140, the drive unit 160 moves, providing power to the threaded screw transmission unit 150 to rotate. At the same time as the threaded screw transmission unit 150 rotates, it provides power to the sliding support seat 130 to move along the axial direction of the guide rail 140, so as to meet the needs of loads with different diameters and realize stepless adjustment of the supported diameter.

[0041] The base 320 is equipped with two support components 200, located between two sliding components 100. The two support components 200 are symmetrically arranged and rotatably connected to the base 320. Each support component 200 has a support base 220 with two holes. The base 320 also has a stabilizing convex plate with holes. The support base 320 is rotatably connected to the base 320 through these three holes. This rotatable connection allows the support components 200 to adaptively adjust their opening according to the surface size of the object when supporting it, ensuring a suitable opening when carrying an object. The symmetrical arrangement of the two support components 200 allows them to share the weight when bearing loads, reducing the weight borne by each individual support component 200 and increasing the overall weight capacity of the shelf.

[0042] Specifically, the support assembly 200 also includes a central support surface 210. The central support surface 210 can be made of a tough material such as industrial rubber sheet, which has strong surface friction to prevent the supported object from sliding, ensuring stability. The industrial rubber sheet also has high overall toughness, providing cushioning while withstanding large torques, preventing damage to the support assembly 200 and extending its service life. The central support surface 210 has grooves 180 evenly distributed on its surface. Compared to a central support surface 210 without grooves 180, this reduces manufacturing costs while supporting the same load, and increases friction with the surface of the supported object, resulting in more stable load bearing.

[0043] The base 320 is also provided with a load-bearing surface 310. The angle between the load-bearing surface 310 and the side support surface 110 is greater than 0 degrees. Furthermore, the sliding component 100 where the side support surface 110 is located and the base where the load-bearing surface 310 is located form a V-shaped structure.

[0044] Specifically, the two side support surfaces 110 and the two central support surfaces 210 jointly support the object. The two central support surfaces 210 are the main support points, and the two side support surfaces 110 are the auxiliary support points. The four support points together form a support surface, and the two groups of support points are relatively close to each other. The support surface formed by the four support points can be regarded as a triangle. The four support points form a triangular support, which supports the object stably. Moreover, the four points support each other at the same time, which can share the weight and avoid damage to the equipment caused by excessive force on a single point. Furthermore, the support of the object is achieved by adjusting the position of the sliding support seat 130 where the side support surface 110 is located and by the adaptive adjustment of the support component 200. In the process of supporting the object, the object is locked by the reaction force of the object to keep it stable.

[0045] The load-bearing component 300 also includes a support part 350, which is fixedly connected to the base 320. The connection method can be welding, bolting, riveting, or a combination thereof. This embodiment does not limit the connection method. The support part 350 can be rectangular, circular, or an irregular polygon. This embodiment does not limit its shape. The support part 350 is fixedly connected to the lower part of the base 320, and the number is not limited. When the shelf needs to be moved, the support part 350 acts as a support component and contacts the transfer vehicle. The support part 350 has a planar structure, which increases the contact area with the transfer vehicle. During the transfer process, the shelf can be stably placed on the transfer vehicle. The increased contact area between the support part 350 and the transfer vehicle reduces the damage to the vehicle's support shelf part during the transfer process.

[0046] The load-bearing component 300 is also equipped with legs 340, which are made of steel, making them sturdy and resistant to damage. The legs 340 are longer than the support portion 350, preventing the support portion 350 from contacting the ground and causing damage when the support frame is placed on the ground for support operations. The legs 340 are located at the four ends of the base 320, or at any position under the base 320; this embodiment does not impose any restrictions. The legs 340 have a rectangular columnar structure, increasing the load-bearing area while ensuring the support portion 350 is not easily damaged. Furthermore, when in contact with the ground, the increased contact area reduces the likelihood of ground damage.

[0047] Specifically, in this embodiment, during transfer, the required number, spacing, and vehicle placement of support racks are determined based on the diameter, length, and mass of the transport tower or monopile. Larger diameters, longer lengths, and higher masses of the tower or monopile require more support racks, denser spacing between racks, and more transport vehicles. Conversely, smaller diameters, shorter lengths, and lower masses of the tower or monopile require fewer support racks, sparser spacing between racks, and fewer transport vehicles. The required support racks are transported to the vicinity of the goods and placed according to the determined spacing and vehicle placement plan. The vehicle placement plan involves the required number and spacing of transport vehicles. The support rack positions are adjusted to ensure all racks are placed in a consistent manner, with their geometric centers aligned. When supporting objects, the objects are hoisted onto the support racks. The rack positions can be adjusted appropriately based on the contact between each support surface and the object.
