Description

Technical Field

[0001] This utility model belongs to the field of transport racking technology, and specifically relates to a multi-layer reversible turnover cart. Background Technology

[0002] In industrialized production, the efficient flow of materials plays a crucial role in improving production efficiency. The importance of trolleys, as reusable transport tools used in factory operations and logistics warehousing for carrying parts and transferring goods, is self-evident.

[0003] However, existing material handling carts have revealed numerous problems in practical applications, especially regarding the turnover efficiency of heavy materials. Due to the weight of the materials, personnel cannot directly transport them from the cart to the automated production line; hoisting operations are typically performed using mechanical devices such as crane arms. However, hoisting operations require that the materials be unobstructed from above, otherwise vertical hoisting is impossible. To improve feeding efficiency, the carts are usually equipped with multi-layered tilting frames, but in existing carts, the rotation axes of each tilting frame are located in the same vertical plane, limiting their tilting angle. Production line hoisting can only successfully hoist the first layer of materials, while the second and lower layers cannot be hoisted due to obstruction by the first layer structure, thus reducing turnover efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-layer reversible turnover vehicle that is convenient for hoisting.

[0005] The technical solution of this utility model is:

[0006] This utility model provides a multi-layer flip-over turnover cart, comprising: a frame, including a base and a plurality of support columns disposed on the base, the base and the support columns forming an accommodating space with an opening on at least one side, the support columns including a first support column away from the opening; and a placement assembly, including a plurality of rotating frames stacked in the accommodating space, each rotating frame having one side flipped and connected to the first support column, and each having a flip center line, wherein the projections of the flip center lines of any two rotating frames on the base do not overlap.

[0007] Optionally, at least two first support columns are provided, and a plurality of support crossbars for flipping and connecting the rotating frame are provided between the at least two first support columns, wherein the projections of any two support crossbars on the base do not overlap at least partially.

[0008] Optionally, there is a height difference between the rotating frame and the base, and there is an offset distance between the rotation center line of the rotating frame and the first support column. Along the height direction of the first support column, the offset distance decreases as the height difference increases.

[0009] Optionally, the support column further includes a second support column disposed near the opening, a vertical column is provided between the first support column and the second support column, the vertical column is disposed near the second support column, and a telescopic rod for driving the rotating frame is provided between the vertical column and the rotating frame.

[0010] Optionally, the maximum angle at which the rotating frame rotates along the rotation center line is greater than or equal to 90°.

[0011] Optionally, the rotating frame and the base are provided with a plurality of product limiting blocks, and / or, the rotating frame is provided with a soft pressing block on the side facing the base, and / or, the frame is provided with a file slot.

[0012] Optionally, the rotating frame includes a top rotating frame away from the base, the top rotating frame being provided with a locking element to prevent the top rotating frame from flipping; and / or, at least one of the rotating frames is detachably connected to the first support column.

[0016] The beneficial technical effects of this utility model are:

[0017] This utility model discloses a multi-layer flip-over turnover cart. By ensuring that the projections of the flipping center lines of any two rotating frames on the base do not overlap (i.e., there is a horizontal distance between the rotation centers of any two rotating frames), structural interference between the rotating frames during the flipping process is effectively avoided. This allows each rotating frame to achieve a large-angle flip, meeting the need for multi-layer unobstructed lifting of heavy materials and greatly improving material flow efficiency. This utility model ensures that there are no obstructions above each layer of material during lifting operations, enabling smooth vertical lifting and avoiding lifting difficulties caused by structural obstructions. This reduces labor costs and enhances the stability and safety of the equipment, meeting the demand for efficient handling of heavy materials in modern industrial production. Furthermore, by setting a reasonable offset distance for the flipping center lines, the forces generated by each rotating frame during the flipping process are evenly distributed, preventing structural deformation or damage caused by force concentration and improving the overall structural stability and service life of the turnover cart.

Detailed Implementation

[0024] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] Please see Figures 1 to 4 As shown, the present invention provides a multi-layer reversible turnover cart 100, including a frame 10 and a placement component disposed on the frame 10.

[0026] The frame 10 includes a base 11 and a plurality of support columns 12 disposed on the base 11. The base 11 and the support columns 12 enclose a receiving space having an opening on at least one side. Materials are placed into the receiving space through the opening.

[0027] In this embodiment, the frame 10 is a cuboid frame. In other embodiments, the frame 10 may also be a frame with other structures, such as a cube, polygon, hemisphere, or sphere.

[0028] Optionally, the base 11 is provided with a tow hook 71 and a trailer column 72. The tow hook 71 and the trailer column 72 are arranged on two opposite sides. By providing the tow hook 71 and trailer column 72 on the base 11 of the turnover cart 100, when multiple multi-layer tiltable turnover carts 100 need to be towed and transported, the tow hook 71 of the next turnover cart 100 can be connected to the trailer column 72 of the previous turnover cart 100, realizing convenient connection of multiple turnover carts 100 and significantly improving turnover efficiency. In addition, the tow hook 71 of this utility model adopts a hinged design and can be folded upward when not in use, effectively reducing the floor space occupied. At the same time, the trailer column 72 is recessed into the inside of the base 11 of the turnover cart 100, which can reduce the distance between two turnover carts 100 when connecting them, further optimizing space utilization.

[0029] Optionally, the base 11 is provided with a forklift slot 90, which has a through hole for the forklift arm to pass through. By providing the forklift slot 90, it is convenient to cooperate with the forklift for operation, making the operation convenient.

[0030] Optionally, the base 11 is also provided with casters 15. The casters 15 can be swivel casters or other wheel structures. By providing casters 15, the movement of the turnover cart 100 is facilitated.

[0031] Optionally, the base 11 is also equipped with a ground brake 80, which allows the moving wheels 15 to detach from or contact the ground. When the trolley 100 needs to be stably placed, operating the ground brake 80 will bring the support member 81 into contact with the ground, causing the moving wheels 15 to detach from the ground, ensuring the stability of the lifting operation. When the trolley 100 needs to be moved, simply operate the ground brake 80 again to detach the support member 81 from the ground, causing the moving wheels 15 to re-contact the ground, allowing for convenient movement. This design not only improves the stability of the trolley 100 during lifting operations but also facilitates its movement and positioning, enhancing the overall user experience.

[0032] The support column 12 includes a first support column 121 located away from the opening and a second support column 122 located close to the opening. The first support column 121 and the second support column 122 form the outer peripheral frame of the vehicle frame 10.

[0033] Optionally, the support column 12 includes a first end near the base 11 and a second end away from the base 11. The first end is provided with a positioning groove 123, and the second end is provided with a positioning protrusion 124 that cooperates with the positioning groove 123. By providing the positioning groove 123 and the positioning protrusion 124, multiple multi-layer flip-over turnover carts 100 can be stacked, increasing storage capacity and improving stability during stacking.

[0034] Furthermore, the placement assembly includes multiple rotating frames 20 stacked within the accommodating space. One side of each rotating frame 20 is flipped and connected to the first support column 121, and each has a flipping center line. The projections of the flipping center lines of any two rotating frames 20 onto the base 11 do not overlap. That is, the rotation centers of any two rotating frames 20 are offset from each other on the horizontal plane, effectively avoiding structural interference between the layers of rotating frames 20 during the flipping process. This allows each layer of rotating frames 20 to achieve a large-angle flip, meeting the need for multi-layer unobstructed lifting of heavy materials and greatly improving material flow efficiency. This invention ensures that there are no obstructions above each layer of material during lifting operations, enabling smooth vertical lifting, avoiding lifting difficulties caused by structural obstructions, reducing labor costs, and enhancing the stability and safety of the equipment, thus meeting the needs of modern industrial production for efficient flow of heavy materials. In addition, by setting a reasonable offset distance for the flipping center line, it helps to evenly distribute the force generated by each layer of rotating frame 20 during the flipping process, avoiding structural deformation or damage caused by force concentration, and improving the structural stability and service life of the entire turnover cart 100.

[0035] Please see Figures 1 to 3 As shown, a plurality of support crossbars 13 for flipping and connecting the rotating frame 20 are provided between the two first support columns 121, and the projections of any two support crossbars 13 on the base 11 do not overlap at least partially. Figure 2 and Figure 3 As shown, the top-level support crossbar 13 is positioned between the two first support columns 121. The lower support crossbar 13 is positioned on the side of the two first support columns 121 near the opening. The next lower support crossbar 13 is connected to the first support column 121 via a connecting rod, thus ensuring that the support crossbars 13 do not overlap on the horizontal plane, thereby allowing...

[0036] Furthermore, the support crossbar 13 is connected to the rotating frame 20 by a hinge or rotating column, etc., so that the rotating frame 20 can rotate at a greater angle along the rotation center line.

[0037] By setting up the support crossbars 13, the frame 10 is stabilized, enhancing its overall structural stability and ensuring it does not deform or sway during material transport and hoisting. Furthermore, each rotating frame 20 is connected to the first support column 121 via a corresponding support crossbar 13. This connection method better distributes the force generated during the rotation of the rotating frame 20, improving connection reliability. Because the support crossbars 13 employ a non-overlapping layout, structural interference between the rotating frames 20 and other components of the frame 10 during rotation is effectively avoided, ensuring each rotating frame 20 can independently and smoothly complete its rotation, improving equipment operating efficiency and reliability. In addition, this layout helps improve space utilization, allowing multiple rotating frames 20 to be arranged compactly, increasing material storage capacity; it also facilitates installation and maintenance, reducing maintenance costs and time; and it enhances operational flexibility, allowing operators to flexibly adjust the angles of each rotating frame 20 according to actual needs, improving work efficiency.

[0038] like Figure 2 and Figure 3 As shown, there is a height difference between the rotating frame 20 and the base 11, and an offset distance between the rotation center line of the rotating frame 20 and the first support column 121. Along the height direction of the first support column 121, the offset distance decreases as the height difference increases. That is, the rotating frame 20 includes a top-level rotating frame 21 away from the base 11 and at least one layer of rotating frames 20 sequentially downwards. The rotation center line of the top-level rotating frame 21 is close to the first support column 121, and the offset distance between the rotation center line of the rotating frame 20 and the first support column 121 increases as it descends. This arrangement ensures that the rotating frames 20 do not interfere with each other during rotation. The rotation center line of the top-level rotating frame 21 is close to the first support column 121, thus occupying less space during rotation, while the distance between the rotation center line of the lower rotating frames 20 and the first support column 121 gradually increases, providing sufficient space for the rotation of the lower rotating frames 20 and ensuring that each rotating frame 20 can perform independent and smooth rotation operations. During hoisting operations, the rotating frames 20 on each layer can smoothly rotate to the appropriate angle, ensuring that there are no obstructions above the material, thereby improving hoisting efficiency, reducing hoisting time and labor costs, and meeting the demand for efficient material flow in modern industrial production.

[0039] Please continue reading. Figure 2 and Figure 3As shown, a column 14 is provided between the first support column 121 and the second support column 122. The column 14 is positioned close to the second support column 122, and a telescopic rod 141 for driving the rotating frame 20 is provided between the column 14 and the rotating frame 20. By positioning the telescopic rod 141 on the column 14 away from the first support column 121, the telescopic rod 141 does not interfere with other installation structures. The maximum rotation angle of the rotating frame 20 is theoretically determined by the stroke of the telescopic rod 141, thus allowing a single rotating frame 20 to rotate to approximately 90° or a greater angle.

[0040] In this embodiment, multiple uprights 14 are provided between the first support column 121 and the second support column 122, and each rotating frame 20 is connected to the corresponding upright 14 via a telescopic rod 141. This arrangement improves the stability of the frame 10, enhances the load-bearing capacity of the entire structure, and ensures that the frame 10 will not deform or shake when multiple rotating frames 20 simultaneously store heavy objects. Furthermore, this layout allows for a more rational installation position of the telescopic rod 141, evenly distributing the force generated by each rotating frame 20 during rotation, thus improving the working efficiency and service life of the telescopic rod 141. In addition, by providing multiple uprights 14, telescopic rods 141 of the same specification can be selected, which not only facilitates production and maintenance, reducing manufacturing and replacement costs, but also ensures the consistency of the rotation action of each rotating frame 20, improving operational accuracy and reliability, and further optimizing the overall performance and user experience of the turnover cart 100.

[0041] In other embodiments, a column 14 is provided between the first support column 121 and the second support column 122, and multiple telescopic rods 141 are connected to the column 14. This invention does not limit this aspect.

[0042] Optionally, the telescopic rod 141 is a nitrogen spring rod or a hydraulic rod, which can provide a stable and adjustable driving force for the rotation of the frame 20, ensuring a smooth and stable rotation process.

[0043] Optionally, the maximum angle at which the rotating frame 20 rotates along the rotation center line is greater than or equal to 90°. During material loading, unloading, or hoisting operations, the rotating frame 20 can achieve a large-angle rotation, resulting in unobstructed overhead access and providing operators with a more spacious operating area. This makes material handling more convenient and unobstructed, effectively improving work efficiency. For hoisting equipment or production lines of different heights and positions, a rotation angle of 90° or higher allows the rotating frame 20 to better adapt, ensuring that materials are accurately placed in designated locations, enhancing the applicability of the turnover cart 100 in complex working conditions. Figure 4 As shown, when the rotating frame 20 is rotated along the rotation center line, the red area is the material placement area, thus providing a large operating space.

[0044] Optionally, the top rotating frame 21 is provided with a locking member 60 to prevent the top rotating frame 21 from flipping. The locking member 60 is used to fix the top rotating frame 21, preventing it from flipping due to vibration or external force, and ensuring the stable stacking of materials.

[0045] Optionally, at least one of the rotating frames 20 is detachably connected to the first support column 121. This design allows the turnover cart 100 to flexibly adapt to materials of different heights and volumes. Users can quickly adjust or replace the rotating frames 20 according to actual needs to meet the storage requirements of shorter or taller materials, ensuring the wide applicability of the turnover cart 100. At the same time, the detachable connection greatly facilitates the replacement and maintenance of the rotating frames 20, reduces operating costs, and improves the maintenance efficiency of the equipment.

[0046] Optionally, the rotating frame 20 and the base 11 are provided with a plurality of product limiting blocks 30. The shape of the product limiting blocks 30 can be designed to conform to the product to improve the stability of the material during transportation and hoisting, and prevent material displacement or collision. This design not only enhances the adaptability of the turnover cart 100 to materials of different shapes and sizes, but also simplifies loading and unloading operations and improves work efficiency. At the same time, the rationally arranged product limiting blocks 30 can optimize space utilization, reduce space waste, and ensure that more material can be stored in a limited space. In addition, by effectively fixing the material, the product limiting blocks 30 also reduce safety hazards during operation and improve the reliability and service life of the equipment.

[0047] Optionally, a soft pressure block 40 is provided on the side of the rotating frame 20 facing the base 11. By providing the soft pressure block 40, the surface of the material can be effectively protected, preventing scratches or damage caused by friction or collision. This is especially suitable for precision parts or high-value materials with easily damaged surfaces. The elastic properties of the soft pressure block 40 make the contact between adjacent rotating frames 20 or between the rotating frame 20 and the base 11 smoother, reducing material displacement caused by bumps or vibrations, thereby improving stability during transportation. Furthermore, the soft pressure block 40 can adapt to materials of different shapes and sizes, filling the gaps between the rotating frame 20 and the material, ensuring the material is tightly fixed and improving space utilization. In addition, the soft pressure block 40 also has a certain shock absorption effect, absorbing the impact force generated during transportation and hoisting, further protecting the material and the structure of the turnover cart 100, and extending the service life of the turnover cart 100.

[0048] Optionally, the frame 10 is provided with a document slot 50. By providing the document slot 50, the materials on the turnover cart 100 can be easily identified, which facilitates management.

[0049] In summary, the multi-layer flip-over turnover cart 100 of this utility model effectively avoids structural interference between the rotating frames 20 during the flipping process by ensuring that the projections of the flipping center lines of any two rotating frames 20 on the base 11 do not overlap. That is, there is a horizontal distance between the rotation centers of adjacent rotating frames 20. This allows each rotating frame 20 to achieve a large-angle flip, meeting the need for multi-layer unobstructed lifting of heavy materials and greatly improving material flow efficiency. Furthermore, by setting a reasonable offset distance for the flipping center lines, the forces generated by each rotating frame 20 during the flipping process are evenly distributed, avoiding structural deformation or damage caused by force concentration, thus improving the structural stability and service life of the entire turnover cart 100. By setting the telescopic rod 141 on the column 14 away from the first support column 121, the telescopic rod 141 does not interfere with other installation structures. The maximum flipping angle of the rotating frame 20 is theoretically determined by the stroke of the telescopic rod 141, allowing a single rotating frame 20 to flip to approximately 90° or a greater angle. This invention ensures that there are no obstructions above each layer of material during hoisting operations, enabling smooth vertical hoisting. It avoids hoisting difficulties caused by structural obstructions, reduces labor costs, and enhances the stability and safety of the equipment, meeting the needs of modern industrial production for efficient handling of heavy materials.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
