Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a layer-changing hoisting machine for a three-dimensional storage warehouse. Background Technology

[0002] With the rapid development of the modern logistics industry, automated warehouses (AS / RS) have been widely used as an efficient storage solution. AS / RS typically employs a combination of hoists and shuttle cars to achieve vertical transportation of goods between different levels. The hoists provide the lifting power, while the shuttle cars handle the horizontal storage and retrieval operations.

[0003] In existing technologies, hoists mainly consist of key components such as a frame structure, drive system, lifting pallet, and counterweight device. The frame, as the supporting structure of the hoist, is typically assembled from profiles such as channel steel, I-beams, T-beams, or angle steel using connectors. To ensure the smooth operation of the counterweight, a dedicated guide rail is required on the outside of the frame. This design means that the width of the counterweight cannot fully utilize the space between the two columns. When the hoist requires a large counterweight, it can only be achieved by increasing the height of the counterweight. This necessitates reserving sufficient space for the counterweight to move when the hoist pallet is at its highest or lowest position, resulting in the overall frame height far exceeding the actual lifting height required for the pallet. Utility Model Content

[0004] The purpose of this utility model is to provide a layer-changing hoist for a three-dimensional storage warehouse, so as to alleviate the technical problem in the prior art where the independently set guide rails in the hoist frame prevent the width of the counterweight from filling the distance between the two columns, resulting in a large overall frame space occupation.

[0005] The present invention provides a layer-changing lifting machine for a three-dimensional storage warehouse, comprising: a column assembly, a beam assembly, and a counterweight assembly; The column assembly includes an outer column and a middle column, and the beam assembly is used to connect the outer column and the middle column. The middle column is disposed between the two outer columns. The intermediate column has a first load-bearing surface, which faces outward and has multiple connecting holes. The first load-bearing surface is partially recessed to form a groove with the opening facing outwards, and the counterweight component is slidably connected to the groove.

[0006] In an optional implementation, There are two outer columns and two middle columns on the same side, with the two middle columns located between the two outer columns, and the grooves on the two outer columns facing away from the middle column located in the middle. The orientation of the grooves in the two intermediate pillars is perpendicular to the orientation of the grooves in the outer pillar.

[0007] In an optional implementation, The intermediate column has a second load-bearing surface, a third load-bearing surface, and an inclined load-bearing surface; The first load-bearing surface is connected to the second load-bearing surface at both ends, and the inclined load-bearing surface is connected to the ends of the two second load-bearing surfaces away from the first load-bearing surface. The third load-bearing surface is connected to the ends of the two inclined load-bearing surfaces away from the second load-bearing surface.

[0008] In an optional implementation, The first load-bearing surface is perpendicular to the second load-bearing surface, and the second load-bearing surface is parallel to the third load-bearing surface; The second load-bearing surface, the third load-bearing surface, and the inclined load-bearing surface are all provided with multiple connection holes.

[0009] In an optional implementation, The outer column and the middle column have the same structure. The two third load-bearing surfaces of the outer column have a spacing to form a mounting groove, which is used for the extension of the crossbeam assembly.

[0010] In an optional implementation, Each of the two third load-bearing surfaces has a guide surface connected to the end away from the inclined load-bearing surface. The guide surface is used to guide the beam assembly into the mounting groove.

[0011] In an optional implementation, The beam assembly includes a first connecting beam; Both ends of the first connecting beam extend into the mounting slots of the two outer columns, and both ends of the first connecting beam are connected to the third load-bearing surfaces of the two outer columns. The bottom surface of the first connecting beam is connected to the top surface of the intermediate column, and the vertical projection of the first connecting beam covers the vertical projection of the first load-bearing surface of the intermediate column.

[0012] In an optional implementation, The beam assembly also includes a second connecting beam; The second connecting beam is located below the first connecting beam, and both ends of the second connecting beam are connected to the third load-bearing surfaces of the two outer columns, respectively.

[0013] In an optional implementation, The counterweight assembly includes a counterweight frame and a counterweight plate body; One or more counterweight bodies are provided inside the counterweight frame, and the counterweight frame is slidably connected to the groove of the middle column.

[0014] In an optional implementation, The counterweight assembly also includes a ski boot; The counterweight frame is provided with sliding shoes on both sides, and the sliding shoes extend into the groove so that the counterweight frame is slidably connected to the groove.

[0015] The present invention provides a layer-changing hoist for a three-dimensional storage facility. It connects outer columns and a middle column via a crossbeam assembly. A connection hole is formed on the first load-bearing surface of the middle column for installing other structural components. A recessed section on the first load-bearing surface forms a groove for sliding connection with a counterweight assembly, replacing the traditional guide rail. This effectively saves space, allowing the maximum width of the counterweight assembly to match the distance between the two outer columns. Therefore, for the same counterweight weight, the height of the counterweight block is significantly reduced. Furthermore, the groove acts as a reinforcing rib of the column structure, effectively improving its strength. This alleviates the technical problem in existing hoist frames where independently installed guide rails prevent the counterweight block from filling the distance between the two columns, resulting in a large overall frame space requirement.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] like Figures 1-5 As shown, the layer-changing lifting machine for an automated storage system provided in this embodiment includes a column assembly 1, a beam assembly 2, and a counterweight assembly 3. The column assembly 1 consists of two outer columns 11 and at least one intermediate column 12, wherein the intermediate column 12 is disposed between the two outer columns 11, and the beam assembly 2 is used to connect the columns and stabilize the overall structure.

[0024] The outer column 11 and the middle column 12 are structurally identical, differing only in their placement and orientation. The identical structure of the outer column 11 and the middle column 12 facilitates standardized production and installation.

[0025] Since the outer column 11 and the middle column 12 are structurally identical, the following text will use the middle column 12 as an example to illustrate its specific structure. Each middle column 12 has a first load-bearing surface 111 facing outward, and multiple connecting holes are distributed on the first load-bearing surface 111, which can be used to fix other components.

[0026] The first load-bearing surface 111 is partially recessed inward to form a groove 1111 with the opening facing outward. This groove 1111 provides a sliding guide path for the counterweight assembly 3, enabling the counterweight assembly 3 to run smoothly in the vertical direction.

[0027] Preferably, there are two outer columns 11 and two middle columns 12 located on the same side. The two middle columns 12 are located between the two outer columns 11. The grooves 1111 on the two outer columns 11 are away from the middle column 12 located in the middle. The orientation of the grooves 1111 on the two middle columns 12 is perpendicular to the orientation of the grooves 1111 on the outer columns 11, so that the installation direction of the outer columns 11 is 90 degrees to the installation direction of the middle columns 12, thereby making the four columns formed by the outer columns 11 and the middle columns 12 evenly distributed.

[0028] The first load-bearing surface 111 of the central column 12 extends into two second load-bearing surfaces 112. The two second load-bearing surfaces 112 are each connected to one end of the inclined load-bearing surface 114. The other end of the inclined load-bearing surface 114 is connected to the third load-bearing surface 113, thus forming a multi-faceted cross-sectional structure.

[0029] The first load-bearing surface 111 is perpendicular to the second load-bearing surface 112, while the second load-bearing surface 112 is parallel to the third load-bearing surface 113. The second load-bearing surface 112, the third load-bearing surface 113, and the inclined load-bearing surface 114 are all provided with multiple connection holes to enhance the connection strength and flexibility with other structural components.

[0030] A certain distance is maintained between the two third load-bearing surfaces 113 on the outer column 11 to form an installation groove for accommodating the end insertion of the crossbeam assembly 2, and the crossbeam assembly 2 extending into the installation groove is fixedly connected to the third load-bearing surface 113 on the outer column 11.

[0031] To further improve assembly convenience, guide surfaces 115 are provided at the ends of the two third load-bearing surfaces 113 on the outer column 11 that are away from the inclined load-bearing surface 114. The guide surfaces 115 have an arc-shaped transition structure, which can guide the crossbeam assembly 2 to smoothly enter the installation slot during the installation process, reduce the difficulty of alignment, and improve assembly efficiency.

[0032] The crossbeam assembly 2 includes a first connecting crossbeam 21 and a second connecting crossbeam 22. The first connecting crossbeam 21 serves as the main load-bearing component, with both ends extending into the mounting grooves of the outer side columns 11 and securely connected to the third load-bearing surface 113 via bolts or other fastening methods. Simultaneously, the bottom surface of the first connecting crossbeam 21 connects to the top of the intermediate column 12, ensuring the stability of the overall structure. In the vertical projection direction, the first connecting crossbeam 21 covers the projection area of ​​the first load-bearing surface 111 of the intermediate column 12, thereby effectively transferring loads and enhancing torsional resistance.

[0033] The second connecting beam 22 is located below the first connecting beam 21. The two ends of the second connecting beam 22 are connected to the third load-bearing surface 113 of the outer columns 11 on both sides, forming a double-layer beam support system, which further enhances the rigidity and seismic resistance of the entire frame.

[0034] It should be noted that in the vertical projection direction, the projections of the second connecting beam 22 and the first connecting beam 21 in the vertical direction are staggered to avoid the second connecting beam 22 obstructing the lifting and lowering of the counterweight assembly 3. Furthermore, since there is a certain distance between the second connecting beam 22 and the outer column 11, the connection and fixation of the second connecting beam 22 and the third load-bearing surface 113 of the outer column 11 can be achieved through an L-shaped bracket.

[0035] The counterweight assembly 3 includes a counterweight frame 31, counterweight body 32, and sliding shoes 311. One or more counterweight bodies 32 can be flexibly arranged inside the counterweight frame 31 according to the required counterweight mass, achieving precise weight adjustment. Sliding shoes 311 are provided on both sides of the counterweight frame 31, and the sliding shoes 311 are embedded in the grooves 1111 of the central column 12, allowing the counterweight assembly 3 to slide back and forth vertically under the guidance of the grooves 1111. Since the grooves 1111 are directly integrated into the first load-bearing surface 111 of the central column 12, there is no need for additional independent guide rails, saving lateral space. This allows the maximum width of the counterweight frame 31 to be close to or even equal to the distance between the two outer columns 11, thereby significantly reducing the overall height of the counterweight block while maintaining the same counterweight mass, which is beneficial for shortening the height of the hoist frame.

[0036] In summary, by embedding the sliding guide structure of the counterweight assembly 3 into the groove 1111 of the intermediate column 12, the layer-changing hoist not only optimizes space utilization, but the groove 1111 itself acts as a reinforcing rib, enhancing the structural strength of the column and improving the bending and torsional resistance of the intermediate column 12. Furthermore, the installation direction of the intermediate column 12 is rotated 90 degrees relative to the outer columns 11, ensuring a uniform distribution of the four columns on the horizontal plane. This helps to evenly distribute the main loads, such as the pallet bearing capacity and counterweight gravity, to each column, avoiding localized stress concentration. The sliding shoe 311 is located on the side of the counterweight frame 31 closest to the intermediate column 12, further ensuring stability and alignment during operation. Ultimately, the machine has a compact structure, making it suitable for space-constrained industrial environments, effectively reducing the requirements for building space and improving the flexibility and utilization of warehouse layout.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
