[0009] The cargo guide rail is T-shaped and vertically installed in the middle of the side of the frame. The conveyor-type cargo platform is connected to the cargo guide rail.

[0010] The lifting drive assembly is connected to the conveyor-type loading platform and the frame respectively. The lifting drive assembly drives the conveyor-type loading platform to rise and fall in coordination through a gear and rack structure.

[0011] In one feasible implementation, a set of lifting drive components is provided, and the set of lifting drive components is fixedly disposed in the middle of the conveyor loading platform;

[0012] Alternatively, the lifting drive assembly may be provided in two sets, with the two sets of lifting drive assemblies fixedly and spaced apart on the conveyor-type cargo platform.

[0013] In one feasible implementation, each set of lifting drive components includes a drive motor, two gears, and two racks. One drive motor is mounted on the conveyor-type cargo platform, and the two racks are respectively vertically mounted on two cargo guide rails in opposite positions. One drive motor is connected to the two racks through the two gears, and the drive motor drives the two gears to rotate synchronously through a synchronous shaft.

[0014] In one feasible implementation, the lifting drive assembly is provided in four groups, which are arranged in a rectangular pattern. Each group of lifting drive assemblies includes a drive motor, a gear, and a rack. The drive motor is fixedly mounted on the conveyor-type loading platform, and the rack is vertically mounted on the loading guide rail. The drive motor is connected to the rack through the gear, and the drive motor drives the conveyor-type loading platform to rise and fall through the gear and the rack.

[0015] In one feasible implementation, the heavy-duty pallet lift further includes a counterweight assembly. Two counterweight assemblies are provided, each of which is connected to the frame via a counterweight guide rail. Each counterweight assembly is also connected to the opposite sides of the conveyor-type loading platform via flexible components to balance the weight of the loading platform.

[0016] In one feasible implementation, the conveyor loading platform includes a frame and a conveying assembly, wherein the frame is connected to the loading guide rail via a limiting assembly, and the conveying assembly is disposed on the frame;

[0017] The lifting drive assembly is located below the frame;

[0018] And / or, the conveying assembly is configured as a chain conveyor assembly or a roller conveyor assembly.

[0019] In one feasible implementation, the conveyor platform further includes a shuttle track disposed beside the conveyor assembly, the shuttle track being used to support the shuttle as it travels onto the conveyor platform and moves up and down with the conveyor platform to change layers.

[0020] In one feasible implementation, at least one set of guiding components is also included, the guiding components being disposed on the conveyor-type loading platform, the guiding components including multiple pairs of oppositely arranged guide wheels, the multiple pairs of guide wheels being respectively clamped to the side of the loading guide rail.

[0021] In one feasible implementation, the cargo guide rail includes a wing and a belly, the rack in the lifting drive assembly is disposed on the inner side of the belly of the cargo guide rail, and the guide wheel in the guide assembly abuts against the outer side of the belly of the cargo guide rail.

[0022] In one feasible implementation, the conveying assembly is provided with a pallet arrival detection component, which is used to detect whether the pallet has reached the designated position.

[0023] Secondly, embodiments of this application provide a warehousing system including a heavy-duty pallet lift as described in any of the first aspects, the heavy-duty pallet lift being used to lift heavy goods.

[0024] Firstly, this application provides a heavy-duty pallet lift, including a frame, a conveyor-type loading platform, a loading guide rail, and a lifting drive assembly. The frame is fixed to the ground or a mounting base. The conveyor-type loading platform is movably disposed within the frame, capable of conveying goods onto its conveying surface and transporting goods from its conveying surface to the outside. It rises and falls within the frame to increase the height of the goods. The loading guide rail is T-shaped and vertically positioned in the middle of the side of the frame, independent of any columns. This eliminates the need for large columns, reducing column costs and making the overall equipment more compact. Furthermore, because the loading guide rail is located in the middle of the frame and contacts the middle of the conveyor-type loading platform, it provides support to the platform, ensuring even stress distribution and preventing damage due to uneven stress.

[0025] The conveyor-type loading platform inside the frame is connected to the loading guide rail. The lifting drive component drives the conveyor-type loading platform to move vertically along the loading guide rail through a gear and rack structure, so as to lift the goods on the conveyor-type loading platform to a specified height.

[0038] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0039] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] With the rapid development of the modern logistics industry towards automation and intelligence, smart warehousing applications are becoming increasingly widespread.

[0043] In related technologies, warehousing systems are equipped with elevators, which are used to lift goods to a designated height so that the goods can be moved by other equipment to the storage location on the shelf at that height.

[0044] In existing hoists, the guide rails that cooperate with the loading platform and the racks used to drive the platform's lifting and lowering are all located on the columns at the edge of the hoist. This results in a relatively large column design and higher cost. Furthermore, to cooperate with the racks on the columns, the gears are located on the side edge of the loading platform, leading to uneven stress on the platform. When the loading platform carries heavy loads, the central area bears a greater force, making it prone to damage.

[0045] To address the aforementioned problems, this application provides a heavy-duty pallet lift and a warehousing system. The solution provided by this application will be described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1As shown in the illustration, this application provides a heavy-duty pallet lift, including a frame 100, a conveyor-type loading platform 200, a counterweight assembly 300, a loading guide rail 400, and a lifting drive assembly 500. The frame 100 is fixed to the ground or some mounting base. The conveyor-type loading platform 200 is movably disposed within the frame 100, allowing it to input goods into its interior or output goods to the outside, and to rise and fall within the frame 100 to increase the height of the goods. For example, the frame 100 is composed of multiple uprights 110 and crossbeams 120 connected sequentially, making it stable and compact. The dimensions and specifications of the uprights 110 and crossbeams 120 can be adapted to the overall lifting load requirements of the equipment and are not limited here.

[0047] A counterweight assembly 300 is movably mounted on the frame 100 and is connected to the conveyor platform 200 via a flexible component (e.g., connecting steel rope or chain) bypassing the top of the frame 100. This allows the weight of the counterweight assembly 300 to balance the weight of the conveyor platform 200, thereby reducing the power consumption of the conveyor platform 200 on the lifting drive assembly 500. For example, the counterweight assembly 300 can be configured as a metal counterweight, with its two sides movably mounted on the frame 100 via counterweight guide rails 700 vertically mounted on the frame 100. For instance, in some examples, the two ends of the counterweight guide rails 700 are fixedly mounted on the frame 100, and the left and right sides of the counterweight assembly 300 have mating grooves that engage with the counterweight guide rails 700.

[0048] The counterweight guide rail 700 is used to limit the counterweight assembly 300, ensuring it can only move vertically and preventing it from swaying. The top of the counterweight assembly 300 is connected to one end of a connecting steel cable, the other end of which passes over a pulley located at the top of the frame 100 and connects to the conveyor platform 200 located within the frame 100. Since the weight of the counterweight assembly 300 is equal to the weight of the conveyor platform 200, they are balanced. Therefore, the lifting drive assembly 500 does not need to provide the driving force to raise and lower the conveyor platform 200, reducing the consumption of the lifting drive assembly 500 while maximizing the load capacity of the conveyor platform 200.

[0049] In this application example, the cargo guide rail 400 is T-shaped and is vertically installed on the side of the frame 100 near the middle position, without being attached to the column 110. This eliminates the need for a large column, reduces the cost of the column 110, and makes the overall equipment more compact.

[0050] like Figure 1As shown, the conveyor-type loading platform 200 inside the frame 100 is connected to the loading guide rail 400 through the guide component 600. The lifting drive component 500 is connected to the conveyor-type loading platform 200 and the frame 100 respectively. The lifting drive component 500 drives the conveyor-type loading platform 200 to move up and down in the vertical direction along the loading guide rail 400 through a gear and rack structure.

[0051] The drive motor 510 of this application drives the lifting of the conveyor-type loading platform 200 through the gear 520 and rack. The transmission method of the gear 520 and rack can improve the transmission accuracy, speed and stability, ensuring that the heavy-duty pallet lift can carry heavier goods.

[0052] Figure 2 yes Figure 1 A schematic diagram showing the connection between the conveyor-type loading platform 200 and the loading guide rail 400.

[0053] Reference Figure 1 and Figure 2 As shown, in some examples, four loading guide rails 400 are provided, which are respectively located on both sides of the frame 100 and are respectively connected to the conveyor loading platform 200 through limiting components. For example, every two loading guide rails 400 are located on one side of the frame 100, and the loading guide rails 400 on both sides of the frame 100 are positioned opposite each other.

[0054] In some examples, the limiting component includes at least one guide component 600 disposed on the conveyor loading platform 200. The guide component 600 includes multiple pairs of opposing guide wheels 610, which are respectively clamped to the sides of the loading guide rail 400.

[0055] In some examples, such as Figure 2 As shown, the guide assembly 600 includes three guide wheels 610, which abut against three sides of the corresponding loading guide rail 400 to allow the conveyor loading platform 200 to move along the loading guide rail 400. Exemplarily, in some examples, the limiting assembly includes two guide assemblies 600, which are vertically spaced on the conveyor loading platform 200, and each guide assembly 600 is connected to the same loading guide rail 400. Each guide assembly 600 has three guide wheels 610, each rotatably mounted on a support. The three guide wheels 610 are arranged in a triangular pattern and abut against three sides of the loading guide rail 400, allowing the conveyor loading platform 200 to move only along the loading guide rail 400. Exemplarily, the rack on the loading guide rail 400 is positioned parallel to the movement trajectory of the guide wheels 610; that is, the rack and guide wheels 610 are side-by-side, with the guide wheels 610 moving on one side of the rack, and the two do not affect each other.

[0056] For example, the cargo guide rail 400 includes a wing and a belly, a rack in the lifting drive assembly 500 is disposed on the inner side of the belly of the cargo guide rail 400, and a guide wheel 610 in the guide assembly 600 abuts against the outer side of the belly of the cargo guide rail 400.

[0057] Figure 3 yes Figure 1 A schematic diagram showing the connection relationship between the counterweight component 300 and the conveyor-type loading platform 200.

[0058] Reference Figure 1 and Figure 3 As shown, exemplarily, the heavy-duty pallet lift includes two counterweight components 300, which are arranged side-by-side on the same side, and each counterweight component 300 is vertically mounted on the frame 100 via a counterweight guide rail 700. Furthermore, each counterweight component 300 is connected to the conveyor platform 200 via at least two connecting steel cables. At least one connecting steel cable passes over a pulley located at the top of the frame 100 and connects to one side of the conveyor platform 200; at least one connecting steel cable passes over a pulley located at the top of the frame 100 and connects to the other side of the conveyor platform 200. The two counterweight components 300 have the same weight, and their total weight is equal to the weight of the conveyor platform 200.

[0059] Figure 4 yes Figure 1 A schematic diagram of the conveyor platform 200 is shown. In some examples, a set of lifting drive assemblies 500 is provided, which are located in the middle of the conveyor platform 200 and drive the conveyor platform 200 to rise and fall by applying a force to the middle of the conveyor platform 200.

[0060] In some other examples, two sets of lifting drive components 500 are provided, and the two sets of lifting drive components 500 are fixedly arranged at intervals on the conveyor platform 200. The two sets of lifting drive components 500 operate simultaneously to drive the conveyor platform 200 to rise and fall.

[0061] Reference Figure 1 and Figure 4 As shown, there are two sets of lifting drive components 500, which are arranged opposite to each other, and the two sets of lifting drive components 500 simultaneously drive the conveyor-type loading platform 200 to rise and fall.

[0062] For example, each lifting drive assembly 500 includes a drive motor 510, two gears 520, and two racks. One drive motor 510 is fixedly mounted on the conveyor platform 200. The two racks are vertically mounted on two opposite loading guide rails 400. The conveying end of the drive motor 510 is connected to a drive shaft, which is rotatably mounted on the conveyor platform 200 via bearings. Gears 520 are fixedly mounted at both ends of the drive shaft, and each gear 520 meshes with a rack. That is, one drive motor 510 is connected to the two racks via the two gears 520. The two drive motors 510 are electrically connected to the same controller, which controls the two drive motors 510 to operate simultaneously. The two drive motors 510 drive the conveyor platform 200 to rise and fall via the gears 520 and racks. Specifically, when the drive motor 510 rotates, it drives the gears 520 to rotate via the drive shaft. Since the rack is in a fixed position, the gear 520 moves along the rack, thereby driving the conveyor platform 200 to rise and fall. It should be noted that using the same controller to control two drive motors 510 to operate simultaneously is existing technology, and since this application does not improve this part of the solution, it will not be described in detail here.

[0063] like Figure 4 As shown, two sets of lifting drive components 500 are arranged opposite each other, with the drive shaft parallel to the bottom of the conveyor platform 200. Four gears 520 are fixedly mounted on the ends of the drive shaft. Each pair of gears 520 is located on one side of the conveyor platform 200, close to the center of the conveyor platform 200, and corresponds to the position of the loading guide rail 400 on the frame 100. That is to say, during the lifting and lowering process of the conveyor platform 200, the conveyor platform 200 has four force-bearing points, ensuring that the conveyor platform 200 is evenly stressed and can bear heavy goods.

[0064] In some examples, four sets of lifting drive assemblies 500 are provided, all mounted on the conveyor platform 200 and arranged in a rectangular pattern. In these examples, each set of lifting drive assemblies 500 includes a drive motor 510, a gear 520, and a rack. The rack is vertically mounted on the corresponding loading guide rail 400, the drive motor 510 is mounted on the conveyor platform 200, and the gear 520 is located at the output end of the drive motor 510, meshing with the rack at the corresponding position. The four drive motors 510 operate simultaneously, driving the conveyor platform 200 to rise and fall. It is understood that by mounting the rack and loading guide rail 400 together, the fixing components for the rack are saved, the installation space within the frame 100 is saved, and costs are reduced, ensuring a compact overall structure of the equipment.

[0065] Reference Figure 1 and Figure 2As shown, in some examples, the conveyor platform 200 includes a frame 210 and a conveying assembly 220. The frame 210 is connected to the loading guide rail 400 via a limiting component. The conveying assembly 220 is fixedly mounted on the frame 210, and the conveying drive assembly of the conveying assembly 220 is located below the frame 210. Similarly, the drive motor 510 and drive shaft of the lifting drive assembly 500 are both located below the frame 210. Since both the conveying drive assembly and the lifting drive assembly 500 are located below the frame 210, the space utilization below the frame 210 is improved, making the mechanism on the conveyor platform 200 more compact. For example, the conveying assembly 220 can be configured as a chain conveyor assembly or a roller conveyor assembly.

[0066] Figure 5 This is a schematic diagram of a conveyor-type loading platform 200 provided in one embodiment of this application;

[0067] Reference Figure 5 As shown, the conveyor loading platform 200 also includes a shuttle track 230, which is located on the side of the conveyor assembly 220. The shuttle track 230 is used to support the shuttle to travel onto the conveyor loading platform 200 and to move up and down with the conveyor loading platform 200 to change layers.

[0068] In addition, the frame 210 is also equipped with a matching limiting wheel 211, which is positioned opposite to the gear 520, forming a space between them that allows only the loading guide rail 400 and the rack to pass through. Specifically, while the rack engages with the gear 520, the matching limiting wheel 211 abuts against the back side of the side of the loading guide rail 400 where the rack is located. It can be understood that because the matching limiting wheel 211 abuts against the back side of the rack, it ensures that the rack and gear 520 are stably engaged together, preventing them from disengaging due to the shaking of the conveyor-type loading platform 200.

[0069] Alternatively, for example, the frame 210 may be formed by sequentially connecting profiles.

[0070] In some examples, the end of the conveying assembly 220 is provided with a pallet positioning detection component. When the pallet moves along the conveying direction of the conveying assembly 220, the pallet positioning detection component can detect whether the pallet has reached the designated position and issue an indication signal. For example, the pallet positioning detection component can be a photoelectric switch.

[0071] Secondly, embodiments of this application also provide a warehousing system, including a heavy-duty pallet lift as described in any of the first aspects, the heavy-duty pallet lift being used to lift heavy goods. Since this warehousing system includes the heavy-duty pallet lift of any of the above-described technical solutions, it possesses all the beneficial effects of the heavy-duty pallet lift of any of the above-described technical solutions, which will not be elaborated further here.

[0072] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.

[0073] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solutions of the embodiments of this application should be included within the protection scope of the embodiments of this application.
