The double-column structure enhances equipment stability and load-bearing capacity. The loading frame is slidably connected to the columns via multiple sets of lifting guide wheels, improving vertical stability and reducing the overturning force generated by bending moment when the forks extend. Simultaneously, the equipment is equipped with safety mechanisms such as anti-fall safety clamps and buffer devices, as well as a horizontal drive system, ensuring safe and stable operation.

Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a stacker crane equipped with a double-column loading platform and a battery pallet storage warehouse. Background Technology

[0002] Stacker cranes are key equipment in the automated production process of new energy batteries. Used in conjunction with charging / discharging cabinets, conveyor lines, and other equipment, they are rail-mounted lifting machines that can repeatedly move in a specific sequence within three-dimensional space (horizontal, vertical, and lateral extension / retraction) to automate battery handling. Because the main equipment they connect with in this process is the charging / discharging cabinet, which is an independent, multi-layered unit with a significant horizontal span between adjacent units.

[0003] Traditional single-station stacker cranes are insufficient to meet the efficiency requirements for battery tray storage and retrieval in the charging and discharging cabinet areas of the new energy industry. If a traditional left-right dual-station stacker crane is used, the horizontal span of the equipment is extremely large due to the influence of the layout of adjacent charging and discharging equipment, which not only affects the structural stability but also wastes space and processing costs.

[0007] A frame component, the frame component including two vertically arranged columns;

[0008] The cargo assembly includes two columns respectively disposed on both sides of the cargo assembly, and the cargo assembly includes two sets of telescopic forks disposed in the vertical direction;

[0009] A vertical drive assembly for driving the cargo assembly to move vertically along the column;

[0010] A horizontal drive component is used to drive the frame component and the cargo component to move in the horizontal direction.

[0011] In one embodiment, the cargo-carrying assembly further includes a cargo-carrying frame, and both sides of the cargo-carrying frame are provided with lifting guide wheel assemblies that cooperate with the columns; the lifting guide wheel assembly includes two lifting side guide wheels, which slide along both sides of the column thickness direction respectively.

[0018] In one embodiment, both ends of the ceiling track and the ground track are provided with buffer devices to buffer impacts from the frame assembly.

[0019] In one embodiment, both ends of the lower crossbeam are provided with cleaning brushes for cleaning the surface of the ground rail, and the angle between the cleaning brushes and the length direction of the ground rail is an acute angle.

[0048] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0049] Please see Figure 1-5 The present invention provides a stacker crane with a double-column loading platform, comprising a frame assembly 1, a loading assembly 2, a vertical drive assembly 3, and a horizontal drive assembly 4.

[0050] The frame component 1 includes two vertically arranged columns 11.

[0051] The two uprights 11 are respectively disposed on both sides of the cargo assembly 2, and the cargo assembly 2 includes two sets of telescopic forks 21 arranged in the vertical direction.

[0052] The vertical drive assembly 3 is used to drive the cargo assembly 2 to move vertically along the column 11;

[0053] The horizontal drive component 4 is used to drive the frame component 1 and the cargo component 2 to move in the horizontal direction.

[0054] In this embodiment, two sets of telescopic forks 21 are arranged vertically. These two sets of forks 21 can operate simultaneously, allowing for simultaneous storage and retrieval of goods on both upper and lower workstations, thus significantly improving the operational efficiency of the warehousing system. Of course, the two sets of telescopic forks 21 in this embodiment can also operate independently, or only one set of forks can operate independently, allowing for flexible adjustments based on work conditions. Furthermore, this embodiment uses double columns 11 to support the loading assembly 2, resulting in greater load capacity and higher stability compared to traditional left-right dual-workstation stacker crane structures.

[0055] In a further embodiment, such as Figure 5 As shown, the cargo loading assembly 2 also includes a cargo loading frame 22, and both sides of the cargo loading frame 22 are provided with lifting guide wheel groups 23 that cooperate with the column 11; the lifting guide wheel group 23 includes two lifting side guide wheels 231, and the two lifting side guide wheels 231 slide along both sides of the width direction of the column 11 respectively.

[0056] The cargo frame 22 is provided with two layers of mounting platforms 221, and the two sets of telescopic forks 21 are respectively installed in the two layers of mounting platforms 221.

[0057] In this embodiment, the cargo frame 22 serves as the main body of the cargo assembly 2 and is used to install other equipment related to the cargo assembly 2, such as telescopic forks 21 and lifting guide wheel assemblies 23. In this embodiment, in order to make the cargo assembly 2 move more stably along the column 11 in the vertical direction, lifting guide wheel assemblies 23 are provided on both sides of the cargo frame 22.

[0058] The lifting guide wheel assembly 23 includes two lifting side guide wheels 231, which are arranged in the thickness direction of the column 11. When the cargo frame 22 moves in the vertical direction, the two lifting side guide wheels 231 can roll along the column 11 to guide the cargo frame 22 and improve the stability of the cargo frame 22 during operation.

[0059] In a further embodiment, two sets of lifting guide wheel sets 23 are provided on both sides of the cargo frame 22, and the two sets of lifting guide wheel sets 23 are respectively located at the upper and lower ends of the cargo frame 22.

[0060] Two sets of lifting guide rollers 23 are provided on both sides of the cargo frame 22, and the two sets of lifting guide rollers 23 are respectively located at the upper and lower ends of the cargo frame 22, thereby further improving the stability of the cargo frame 22 when moving vertically along the column 11. In addition, since the two sets of telescopic forks 21 in this embodiment are arranged vertically, the overall height of the cargo frame 22 is higher than that of the prior art, resulting in a greater vertical height difference between the upper and lower sets of lifting guide rollers 23. Therefore, when the telescopic forks 21 extend outward, the bending moment arm of the lifting guide rollers 23 is smaller, thereby improving the stability of the overall structure and increasing the service life of the lifting guide rollers 231.

[0061] In a further embodiment, each set of lifting guide wheels 23 also includes an end face pulley 232, which directly abuts against the opposite end faces of the two columns 11, thereby further improving the stability of the cargo frame 22 in the vertical direction.

[0062] In a further embodiment, anti-fall safety clamps 5 are provided on both sides of the cargo frame 22, and slide rails 111 are provided on both columns 11. The two sets of anti-fall safety clamps 5 slide along the slide rails 111 on the two columns 11 respectively. The track in this embodiment is a T-shaped track.

[0063] In this embodiment, a fall arrestor 5 is installed, which is triggered by a speed limiter. The fall arrestor 5 and the speed limiter are mechanical safety components. Once the speed exceeds its mechanical property threshold, the fall arrestor 5 will be automatically triggered to clamp the T-shaped rail, thereby preventing the cargo component 2 from falling continuously and causing an accident, thus improving the overall structural safety.

[0064] In a further embodiment, such as Figure 3 and Figure 4 As shown, the horizontal drive assembly 4 includes a ground rail 41, a ceiling rail 42, and a wheel box 43; the ground rail 41 and the ceiling rail 42 are arranged in parallel.

[0065] The upper ends of the two columns 11 are fixedly connected to the upper crossbeam 12, and the upper crossbeam 12 is provided with an upper pulley 121 that cooperates with the ceiling track 42;

[0066] The lower ends of the two columns 11 are fixedly connected to the lower crossbeam 13. The lower crossbeam 13 is provided with a sliding wheel 131 that cooperates with the ground rail 41. The traveling wheel box 43 is fixedly installed on the lower crossbeam 13. The traveling wheel box 43 is provided with a traveling wheel 431 and a drive motor 432 that drives the traveling wheel 431 to roll along the ground rail 41.

[0067] In this embodiment, the upper ends of the two columns 11 are fixedly connected to the same upper crossbeam 12 by welding; the lower ends of the two columns 11 are fixedly connected to the same lower crossbeam 13 by welding, so that the two columns 11, the upper crossbeam 12 and the lower crossbeam 13 cooperate to form a solid frame component 1.

[0068] Several upper pulleys 121 that cooperate with the ceiling track 42 are provided on the upper crossbeam 12. The upper pulleys 121 are divided into two groups and located on both sides of the ceiling track 42 respectively. So when the frame assembly 1 moves horizontally along the ceiling track 42, the upper pulleys 121 can play a guiding role, making the frame assembly 1 move more stably in the horizontal direction.

[0069] Correspondingly, a number of sliding rollers 131 that cooperate with the ground rail 41 are provided on the lower crossbeam 13. The sliding rollers 131 are divided into two groups, and the two groups of sliding rollers 131 are located on both sides of the ground rail 41. Thus, when the frame assembly 1 moves horizontally along the ceiling rail 42, the sliding rollers 131 can play a guiding role, making the frame assembly 1 move more stably in the horizontal direction.

[0070] The drive motor 432 drives the traveling wheels 431 to rotate, enabling the traveling wheels 431 to roll along the ground rail 41, thereby realizing the horizontal movement of the frame assembly 1 and the cargo assembly 2. In conjunction with the pulleys 121 and 131, the entire frame assembly 1 moves more stably on the overhead rail 42 and the ground rail 41.

[0071] In a further embodiment, both ends of the ceiling track 42 and the ground track 41 are provided with buffer devices 6 to buffer impacts from the frame assembly 1.

[0072] The buffer device 6 in this embodiment is a polyurethane buffer, which can prevent the frame assembly 1 and the cargo assembly 2 from derailing.

[0073] In a further embodiment, both ends of the lower crossbeam 13 are provided with cleaning brushes 7 for cleaning the surface of the ground rail 41, and the angle between the cleaning brushes 7 and the length direction of the ground rail 41 is an acute angle.

[0074] The cleaning brush 7 can remove debris from the ground rail 41, ensuring the stable operation of the traveling wheel 431. At the same time, the cleaning brush 7 forms an acute angle with the ground rail 41 along its length, which allows debris to move along the inclined cleaning brush 7 as it moves along the ground rail 41, eventually falling off the ground rail 41, thus improving the cleaning effect of the cleaning brush 7.

[0075] In one embodiment, the vertical drive assembly 3 includes a vertical motor 31, and the output end of the vertical motor 31 is provided with a first drive wheel 32 and a second drive wheel 33;

[0076] A first drive rope 321 is wound around the first drive wheel 32; a first guide component is provided on the top of the drive assembly, and the first drive rope 321 is fixedly connected to the frame assembly 1 after passing around the first guide component;

[0077] A second drive rope 331 is wound around the second drive wheel 33; a second guide component is provided on the top of the drive assembly, and the second drive rope 331 is fixedly connected to the frame assembly 1 after passing around the second guide component;

[0078] The ends of the first drive rope 321 and the second drive rope 331 are respectively connected to the two sides of the frame assembly 1.

[0079] In this embodiment, a vertical motor 31 simultaneously drives the first drive wheel 32 and the second drive wheel 33. The simultaneous rotation of the first drive wheel 32 and the second drive wheel 33 allows for the simultaneous "winding in" and "unwinding out" of the first drive rope 321 and the second drive rope 331, thereby enabling the frame assembly 1 to rise and fall vertically. Furthermore, the first drive rope 321 and the second drive rope 331 are connected to both sides of the frame assembly 1, allowing them to act on both sides of the frame assembly 1 and maintain its stability.

[0080] In this embodiment, the vertical motor 31 is fixedly mounted on one of the columns 11. The first guide component includes a first guide wheel 34, which is located at the top of the same column 11 as the vertical motor 31. The first drive rope 321 passes around the first guide wheel 34 and is fixedly connected to the frame component 1.

[0081] The second guide assembly includes a second guide wheel 35 and a third guide wheel 36. The second guide wheel 35 is located on the top of one of the columns 11, and the third guide wheel 36 is located on the top of the other column 11. The second drive rope 331 passes around the second guide wheel 35 and the third guide wheel 36 and is fixedly connected to the frame assembly 1.

[0082] In another embodiment, such as Figure 6 As shown, this embodiment also provides a battery tray storage room, including: two rows of parallel charging cabinet groups 8, the charging cabinet group 8 including a plurality of charging cabinets 81, and a plurality of charging compartments 82 for charging battery trays are arranged vertically on the plurality of charging cabinets 81.

[0083] The stacker crane with a double-column loading platform is installed between the two rows of charging cabinet groups 8.

[0084] The height between adjacent charging compartments 82 on each of the charging cabinets 81 is the same as the height between the two sets of telescopic forks 21.

[0085] A battery conveyor line 9 is also provided on one side of the charging cabinet group 8. The battery conveyor line 9 has two layers and is used to temporarily store battery trays.

[0086] In this embodiment, a stacker crane equipped with a double-column loading platform is placed between two charging cabinet groups 8. Through the vertical drive component 3 and the horizontal drive component 4, the loading component 2 is controlled to move in the vertical and horizontal directions. At the same time, in conjunction with the movement of two sets of telescopic forks 21, the storage and retrieval operations of battery trays on the two charging compartments 82 can be performed simultaneously, which effectively improves the efficiency of battery tray storage and retrieval.

[0087] This invention features two sets of telescopic forks 21 arranged vertically, which can operate simultaneously, enabling simultaneous storage and retrieval of goods on both upper and lower workstations, thus significantly improving the operational efficiency of the warehousing system. In this embodiment, double columns 11 support the loading assembly 2, resulting in greater load capacity and higher stability compared to traditional stacker cranes with dual left and right workstations. The two sets of telescopic forks 21 are arranged vertically, leading to a higher overall loading frame 22 compared to existing technologies. This results in a greater vertical height difference between the upper and lower lifting guide wheel assemblies 23 on the loading frame 22, thus reducing the bending moment arm of the lifting guide wheel assembly 23 when the telescopic forks 21 extend outwards. This improves the overall structural stability and extends the service life of the lifting guide wheels 231.

[0088] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
