Description

TECHNICAL FIELD

[0001] The present application relates to the field of logistics transportation, in particular to a folding rack and a transportation method. BACKGROUND

[0002] In the field of automobile parts manufacturing and logistics, the direction machine as a key safety component, its efficient and safe transportation is an important link to ensure the smooth operation of the supply chain. At present, the direction machine special transportation rack commonly used in the industry is mainly based on the design of traditional fixed frame structure. This kind of rack is usually composed of rigid metal skeleton, with specific positioning and supporting structure to ensure the stability of the direction machine during transportation and prevent damage caused by bumping.

[0003] However, this traditional fixed rack design has significant limitations, especially in terms of transportation efficiency: 1. Large volume in full load state: In order to firmly accommodate and protect the irregularly shaped and relatively large direction machine parts, the rack structure itself is often designed to be large in size and occupy more space. This directly leads to a strict limitation on the number of direction machines that can be loaded in the transportation vehicle (such as trucks, containers), and the loading capacity of single transportation cannot be maximized. 2. Serious waste of space during empty return: When the rack completes the transportation task of the direction machine and needs to return to the delivery location or go to the next loading point, its volume does not have any substantial reduction. The rack structure that occupies a large space in full load state still maintains the same large size in empty state. This means that the transportation vehicle during return is essentially transporting a large amount of "air", and the effective payload space is severely occupied by the idle rack structure.

[0004] Therefore, it is urgent to develop a new type of direction machine transportation rack that can effectively solve the above problems, especially significantly reduce the volume during empty return, which has practical needs and important economic value for improving the efficiency of the entire automobile parts logistics chain and reducing operating costs.

DETAILED DESCRIPTION

[0107] The present application provides a folding rack and a transportation method. In order to make the purpose, technical scheme and effects of the present application more clear and definite, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0108] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence, and it should be understood that such data can be interchanged under appropriate circumstances. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0109] Combination Figure 1 and Figure 7As shown, the folding rack disclosed in the present application comprises a base 1 and a folding frame 2 mounted thereon. The folding frame 2 is rotatably connected with the base 1 and has two states of folding and unfolding: in the folding state, it can be compactly folded above the base 1; in the unfolded state, it forms a stable space above the base 1 for loading direction machines. The key benefit of this design is to significantly improve the space utilization, maximize the storage and transportation space in the folding state when not in use, and provide a stable and reliable loading platform in the unfolded state when in use. Through state switching, the minimum space occupation (folding state) and maximum use function (unfolding state) are flexibly converted, optimizing the efficiency of warehouse and operation process, thereby realizing the high unification of storage convenience and use functionality.

[0110] Further, in a preferred embodiment of the folding rack of the present application, in combination with Figure 2 and Figure 8 As shown, the base 1 is composed of a bottom frame 11 and a connecting piece 12 perpendicular to the plane of the bottom frame and fixed to the bottom frame, forming a stable support base. The folding frame 2 is movably connected with the connecting piece 12 through a rotatable connecting piece, realizing the rotational movement of the folding frame 2 in the vertical direction of the bottom frame. This design enables the folding frame 2 to be efficiently folded above the base 1 to save storage space, and to form a direction machine loading space when unfolded. At the same time, the connecting piece 12 optimizes the force transmission path, improving the overall durability of the rack.

[0111] Preferably, as shown in Figure 2 In another preferred embodiment of the folding rack of the present application, the folding frame 2 is composed of a support column 21 and a material loading frame. The first end of the support column 21 is rotatably connected with the connecting piece 12, and the second end extends away from the bottom frame 11, so that the support column 21 can rotate around the connecting point with the connecting piece 12 to the direction close to the bottom frame 11 to be parallel with the bottom frame 11, facilitating storage and space saving. Moreover, the support column 21 can also rotate reversely around the connecting point of the connecting piece 12 from parallel with the bottom frame 11 to perpendicular with the bottom frame 11. One end of the material loading frame is rotatably connected with the support column 21, and the other end (i.e. the free end) extends in the direction parallel with the bottom frame 11, so that the material loading frame can rotate around the connecting point with the support column 21 to the direction away from the bottom frame 11 to be perpendicular with the bottom frame 11, facilitating the placement and retrieval of materials. Moreover, the material loading frame can also rotate reversely around the connecting point with the support column 21 from parallel with the bottom frame 11 to perpendicular with the bottom frame 11. This structural design realizes the flexible rotation and space optimization of the folding frame 2, improving the use convenience and space utilization of the rack.

[0112] The bottom frame 11 is connected to at least two connecting members 12, or more connecting members, each of which is arranged on opposite sides of the bottom frame 11, and each connecting member 12 is connected to a support column 21, and the area between the two support columns 21 forms a support area. Each support column 21 is connected to a support frame or a plurality of support frames, or each support frame is connected to two or more support columns 21, and preferably, each support frame is connected to only one side of the support column 21, for example, the support frame is connected to two or three support columns 21 on the same side, and the free end of the support frame extends to the other side.

[0113] When there is more than one support frame, the support frames can be arranged side by side in a direction parallel to the bottom frame 11 (e.g., connected in a row), or arranged in sequence in a direction perpendicular to the bottom frame 11, or as shown in Figure 1 , the support frames are arranged in multiple layers (at least two layers), and each layer is connected to at least two support frames side by side.

[0114] Further, in another preferred embodiment of the folding rack of the present application, the connecting members 12 can be arranged in pairs vertically on the two sides of the two bottom frames 11, and correspondingly, the connecting members 12 are also arranged in pairs, and each pair of support frames extends towards each other without contacting, thereby forming a two-part symmetrical structure. This structure makes the folding rack more stable during support and rotation, and at the same time, through the symmetrical arrangement on both sides, the overall balance and carrying capacity of the rack are enhanced, and the reliability and safety of the rack during use and folding are improved.

[0115] Preferably, in another preferred embodiment of the folding rack of the present application, the connecting members 12 are provided with grooves (e.g., the connecting members 12 are made of channel steel), and the openings of the grooves of the connecting members 12 on the same side are the same and face the other side, forming a guide structure, and in the case of a pair of connecting members 12, the openings of the grooves of each pair of connecting members 12 face each other. The connecting members 12 are inserted and connected with the support columns 21 through the grooves, and specifically, a rotatable connecting member is arranged in the groove, and the first end of the support column 21 is inserted into the groove of the connecting member 12 and connected with the rotatable connecting member, so that the support column 21 can be rotated inwardly to be parallel to the bottom frame 11; the support frame is hinged to the support column 21, and can be fixed parallel to the bottom frame 11 to form a loading space, or can be folded inwardly synchronously. In the folded state, the support column 21 and the support frame are completely folded into the plane of the bottom frame 11 by synchronous inward rotation, and the storage efficiency is improved by more than 50%; and the unified inward folding path simplifies the operation logic and avoids the risk of structural interference.

[0116] Further, in combination with Figure 2 and Figure 3As shown, in another preferred embodiment of the folding shelf of the present application, the structure of the shelf is further optimized. The shelf comprises a bearing rod 221 and a connecting rod 222, the bearing rod 221 is connected vertically with the support column 21, the connecting rod 222 is parallel to the plane where the support column is located, and the bearing rod 221 is connected between the connecting rod 222 and the support column 21, thereby enhancing the overall structural stability of the shelf. For example, each connecting rod 222 can be connected with 2 or 3 or more bearing rods 221, and each bearing rod 221 is connected with one support column 21. This design not only improves the carrying capacity of the shelf, but also ensures the reliability and durability during folding and use through the reinforcing effect of the connecting rod 222, thereby prolonging the service life and improving the safety of the shelf.

[0117] Preferably, as Figure 9 As shown, in another preferred embodiment of the folding shelf of the present application, a pad 223 is arranged on the surface of the connecting rod 222 away from the bottom frame 11, which is used to place the direction machine. The pad 223 is arranged according to the shape of the direction machine, and the pad 223 is detachable. Different pads 223 can be replaced according to the shape and size of the direction machine, which can firmly fix the direction machine on the shelf, effectively prevent the direction machine from shifting or falling during transportation and storage, ensure the integrity and safety of the direction machine, avoid damage and quality problems caused by insecure fixing, and improve the adaptability of the shelf.

[0118] Further, in another preferred embodiment of the folding shelf of the present application, the folding shelf 2 is further provided with a fixed frame 224 structure. The fixed frame 224 is rotatably connected with the support column 21 and is perpendicular to the support column 21 (parallel to the bottom frame 11 or the shelf), and the shelf is located in the space between the fixed frame 224 and the bottom frame 11. The end of the fixed frame 224 away from the support column 21 is provided with a pressing block 226 facing the bottom frame 11. The fixed frame 224 can be arranged on only one of the support columns 21, for example, on one side of the support column 21, or can be arranged on both sides of the support column 21. The fixed frame 224 can be rotated away from the bottom frame 11 to be perpendicular to the bottom frame 11. This design makes the folding shelf provide additional fixation and stability through the fixed frame 224 and the pressing block 226 during use, thereby further enhancing the carrying capacity and safety of the shelf.

[0119] Preferably, in another preferred embodiment of the folding shelf of the present application, the surface of the connecting rod 222 facing the bottom frame is also provided with a pressing block 226. After the shelf is rotated to be parallel to the bottom frame 11, the pressing block 226 of the connecting rod 222 abuts against the direction machine on the other layer of the shelf facing the pressing block 226, which is used to fix the direction machine. The pressing block 226 is arranged according to the shape of the direction machine, and the pressing block 226 is detachable. Different pressing blocks 226 can be replaced according to the shape and size of the direction machine, thereby improving the adaptability of the shelf.

[0120] Furthermore, in another preferred embodiment of the folding rack of this application, the free end of the carrier (preferably the support rod 221) is rotatably connected to a pressure frame 23 arranged parallel to the bottom frame 11. The pressure frame 23 may be connected to one carrier (preferably the support rod 221) or between two or more support rods 221 on the same side. The pressure frame 23 can rotate toward the bottom frame 11 to be perpendicular to the bottom frame 11 (the state perpendicular to the bottom frame 11). The pressure block 226 is disposed on the surface of the pressure frame 23 facing the bottom frame 11. When the pressure frame 23 is perpendicular to the bottom frame 11, the pressure block 226 presses on the steering mechanism of the carrier facing the pressure block 226, fixing the steering mechanism. The rotatable pressure frame 23 improves the stability and adaptability of fixing the steering mechanism, and at the same time improves the flexibility of folding the overall structure.

[0121] Better, such as Figure 6 As shown, in a preferred embodiment of the folding rack of this application, the pressure frame 23 is connected to the support rod 221 via a damping hinge 225. The damping hinge 225 provides a self-locking or hovering function, allowing the pressure frame 23 to remain stable at any angle, preventing the steering gear from accidentally shifting due to gravity or external forces, ensuring the structural reliability of the loading space, and improving the adaptability of the pressure frame 23 to steering gears of different sizes. The damping hinge 225 typically contains a hydraulic or friction buffer mechanism, generating controllable resistance when the support rod 221 and the pressure frame 23 rotate relative to each other. The damping hinge 225 absorbs kinetic energy through internal damping materials or mechanical structures, enabling the pressure frame 23 to move slowly during folding / unfolding, avoiding impact vibrations to the steering gear caused by rapid folding, and protecting precision components from damage.

[0122] Preferably, in a preferred embodiment of the folding rack of this application, the pad 223 is made of polyurethane elastomer to absorb the energy of vehicle vibration and prevent damage to the precision components of the steering gear; the modular quick-release design of the pad 223 allows for quick replacement to adapt to different models of steering gear, improving switching efficiency; the pad 223 isolates hard metal contact, reduces surface wear of the connecting rod 222, and extends service life.

[0123] Furthermore, such as Figure 4As shown, in another preferred embodiment of the folding rack of this application, the rack further includes a first rotating member 227 fixedly disposed on the support column 21. The support column 21 and the rack (preferably the support rod 221) are rotatably connected via the first rotating member 227. The first rotating member 227 and the support rod 221 are rotatably connected. Rotating the support rod 221 outward makes it parallel to the support column 21, and then folding the support column 21 inward puts the rack in a folded state. At this time, the first rotating member 227 is perpendicular to the support rod 221 and the support column 21. The first rotating member 227 has a preset length, and the length of each first rotating member 227 can be different or the same. In this way, the distance between the connection point between the first rotating member 227 and the support rod 221 and the support column 21 can be adjusted according to this length, thereby determining the distance between the support rod 221 and the support column 21 in the folded state, which can better control the compressed volume after folding.

[0124] Preferably, in another preferred embodiment of the folding rack of this application, a circular hole is provided on the first rotating member 227. The circular hole is perpendicular to the plane where the pair of support columns 21 are located and faces the support rod 221. An oblong hole is provided at the end of the support rod 221 near the support column 21 along the length direction. The first rotating member 227 and the support rod 221 are connected by bolts 228 passing through the circular hole and the oblong hole. The oblong hole allows the support rod 221 to retract downward when it rotates outward to be perpendicular to the bottom frame 11, reducing the total length of the support rod 221 and the support column 21 in the folded state, and further reducing the folded volume.

[0125] Furthermore, in another preferred embodiment of the folding rack of this application, a limiting plate 229 is provided on the support column 21. The limiting plate 229 includes at least a first plate perpendicular to the support column 21. The first plate contacts the surface of the end of the bearing rod 221 away from the bottom frame 11. The bearing rod 221 is perpendicular to the support column 21, or, as... Figure 4 As shown, the limiting plate 229 also includes a second plate perpendicular to the first plate (parallel to the support column 21). The end of the support rod 221 connected to the support column 21 is arc-shaped to prevent the support rod 221 from contacting the second plate of the limiting plate 229 when rotating. Tightening the bolt 228, through the bidirectional limiting of the bolt 228 and the limiting plate 229, prevents the support rod 221 from accidentally rotating and moving horizontally when it is parallel to the bottom frame 11, thus preventing displacement of the steering gear and improving the stability of the entire mechanism. When the steering gear is mounted on the support rod 221, the support rod 221 is subjected to a force towards the center of the bottom frame 11. Therefore, the end of the support rod 221 near the support column 21 abuts against the first plate, allowing the support rod 221 to remain parallel to the bottom frame 11. The end of the support rod 221 near the support column abuts against the second plate to prevent the support rod 221 from sliding towards the support column 21 along the direction of the oblong hole.

[0126] Further, in another preferred embodiment of the folding rack of the present application, the bottom of the support column 21 is provided with a second rotating member 230 (as a rotating connecting member connecting the support column 21 and the connecting member 12), the support column 21 is connected to the end of the second rotating member 230, and the connecting member 12 is provided with an ear plate 121 protruding towards the loading area of the rack, and the second rotating member 230 is rotatably connected with the ear plate 121. The second rotating member 230 is arranged so that the support column 21 can be more closely inserted into the connecting member 12, and will not interfere with the connecting member 12 when the support column 21 rotates. At the same time, the length of the second rotating member 230 can control the distance between the support column 21 and the bottom frame 11 when the support column 21 is folded, and better adjust the volume after folding. The first rotating member 227 is arranged on the side of the second rotating member 230 away from the bottom frame 11, and the rotating connection point of the second rotating member 230 and the connecting member 12 serves as the rotating shaft of the support column 21. When the support column 21 is pushed, it rotates around the rotating shaft to be parallel to the bottom frame 11.

[0127] Preferably, in another preferred embodiment of the folding rack of the present application, a bolt hole is formed in the end of the connecting member 12 away from the bottom frame 11, and the connecting member 12 is connected with the support column 21 by a bolt, so that the support column 21 is fixed and locked in the unfolded state, avoiding accidental rotation of the support column 21.

[0128] Further, in combination with Figure 1 and Figure 2 shown, in a preferred embodiment of the folding rack of the present application, a plurality of racks are arranged along the vertical direction of the support column 21 and the bottom frame 11 (each rack is independently hinged to the support column 21 at different heights), forming a layered loading unit. The space utilization is improved, and the vertical stacking design is improved to increase the loading capacity of a single rack, and the transportation efficiency of the production line is doubled. The multiple layers of racks are folded and folded synchronously, reducing the cost of warehousing. Upgrading the production line compatibility: the height-adjustable design is compatible with different sizes and directions of machine mixing, improving switching efficiency. Independent bearing of each layer ensures that heavy direction machines and precision components are layered to avoid shock isolation. Operation efficiency optimization: modular layered structure supports single-layer maintenance and replacement, reducing maintenance costs.

[0129] The folding rack of the present application expands the loading space in the vertical dimension, while maintaining the ultra-thin folding characteristics to achieve three-dimensional loading: when unfolded, it forms a three-dimensional warehouse type transportation unit, and the single carrying capacity is 3 times that of the traditional rack; when folded, each layer of the rack is synchronously turned in along the track of the support column 21. The core contradiction between the limited space of the large-scale assembly workshop and the transportation batch demand is solved, breaking through the industry bottleneck.

[0130] Preferably, Figure 5 for Figure 1 the enlarged view of the connection between the bottom frame 11 and the support column 21 in B of the above figure, as Figure 5As shown, the folding rack of the direction machine of the present application is provided with a gas spring 24 hinged structure at the intersection of the bottom frame 11 and the support column 21, and the two ends of the gas spring 24 are rigidly connected with the bottom frame 11 and the side wall of the support column 21, respectively, and together with the second rotating part 230, a bidirectional linkage mechanism is formed. The folding operation is labor-saving, the state switching is stable, and the unfolded state is self-locked and stable.

[0131] The gas spring can play the role of auxiliary support and buffering during the unfolding and folding of the folding rack, making the operation more labor-saving and stable, and also reducing the impact and wear caused by frequent operation on the structure of the rack, prolonging the service life of the rack.

[0132] The present application also provides a transportation method, which specifically comprises the following steps:

[0133] The base 1 is placed at the loading site, the direction machine is loaded onto the folding rack 2 and fixed, the loaded direction machine is transported to the unloading site and unloaded. After unloading is completed, the folding rack 2 is pushed to rotate relative to the base 1, realizing the folding operation. This method realizes the folding function through the relative rotation of the folding rack 2 and the base 1, which not only facilitates transportation and storage, but also improves the flexibility and efficiency of the transportation process, simplifies the operation process, and reduces labor costs.

[0134] Further, in a preferred embodiment of the transportation method of the present application, the base 1 is composed of a bottom frame 11 and a connecting piece 12 fixed thereon, the folding rack 2 includes a support column 21 arranged perpendicularly to the bottom frame 11 and rotationally connected with the connecting piece 12, and a carrier arranged parallel to the bottom frame 11 and rotationally connected with the support column 21. After the unloading of the direction machine is completed, the bolts on the connecting piece 12 and the support column 21 are loosened, the carrier is pushed away from the bottom frame 11 to rotate to be perpendicular to the bottom frame 11, and then the support column 21 is pushed towards the bottom frame 11 to rotate to be parallel to the bottom frame 11, and the connecting piece 12 and the support column 21 are fixed by bolts to prevent accidental opening after folding, thereby completing the folding operation. This structure and method not only realize the rapid folding of the folding rack 2, but also improve the space utilization, facilitate transportation and storage, and improve the transportation efficiency and use convenience.

[0135] Preferably, in another preferred embodiment of the transportation method of the present application, the connecting pieces 12 are arranged in pairs on both sides of the upper surface of the base frame 11, and each connecting piece 12 is connected with a support column 21. In the folding process, first, the object carrier and the support column on the same side of the upper surface of the base frame 11 are pushed in sequence to rotate to be perpendicular to the base frame 11 and parallel to the base frame 11, respectively; then the object carrier and the support column on the other side are pushed in sequence to complete the folding operation of the entire folding frame 2. This design of arranging in pairs and pushing in steps not only enhances the structural stability of the folding frame 2, but also makes the folding process more orderly and efficient, further improving the convenience and reliability of operation, reducing the risk of misoperation in the folding process, and improving the overall transportation and storage efficiency.

[0136] Further, in another preferred embodiment of the transportation method of the present application, the folding frame 2 is provided with a fixed frame 224 which is arranged parallel to the base frame 11 and rotatably connected with the support column 21, and the end of the fixed frame 224 is provided with a pressing block 226 which is perpendicular and downward to the base frame 11. In the folding operation, the fixed frame 224 is first pushed to be perpendicular to the base frame 11, and then the object carrier and the support column 21 are pushed to complete the folding. This structural design provides additional support and stability for the folding frame 2 through the cooperation of the fixed frame 224 and the pressing block 226, further enhancing the reliability of the folding frame 2 during transportation and folding, and improving the overall transportation efficiency and use safety.

[0137] Preferably, in another preferred embodiment of the transportation method of the present application, the end of the connecting rod 222 is provided with a rotatable pad 223 for providing additional support and stability during the folding operation. Before rotating the bearing rod 221, the pad 223 is first pushed to rotate to be parallel to the base frame 11 to ensure a smooth and smooth folding process. This design not only improves the stability and safety of the folding frame 2 during operation, but also further simplifies the operation steps, reduces the operation difficulty, improves the transportation and storage efficiency, and reduces the risk of damage caused by improper operation.

[0138] Further, in another preferred embodiment of the transportation method of the present application, the object carrier further comprises a first rotating piece 227 fixedly arranged on the inner side of the support column 21, the first rotating piece 227 is in the shape of a long strip, the first rotating piece 227 and the bearing rod 221 are rotatably connected, the bearing rod 221 is rotated outward to be parallel to the support column 21, and then the support column 21 is folded inward to be in a folded state, at this time the first rotating piece 227 is perpendicular to the bearing rod 221 and the support column 21, the length of the first rotating piece 227 determines the distance between the bearing rod 221 and the support column 21 in the folded state, which can better control the compressed volume after folding.

[0140] Further, in another preferred embodiment of the transportation method of the present application, a limiting plate 229 is arranged on the support column 21 close to the bearing rod 221 and perpendicular to the bottom frame 11, the bolt 228 limits the inward horizontal movement of the bearing rod 221 when the bearing rod 221 is perpendicular to the support column 21, and the limiting plate 229 limits the outward horizontal movement of the bearing rod 221, so that the horizontal movement of the bearing rod 221 is prevented when it is parallel to the bottom frame 11, the displacement of the mechanism is prevented, and the stability of the whole mechanism is improved.

When folding, the uppermost carrier is first pushed to be perpendicular to the base frame 11, and then the carriers are sequentially pushed until all carriers are perpendicular to the base frame 11, and then the support column 21 is pushed inward to be parallel to the base frame 11.
