Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically to a device for synchronously forking and handling aluminum ingot stacks. Background Technology

[0002] In the aluminum industry, molten aluminum, as the main raw material for producing stacked aluminum products, needs to be mixed with other metal elements before being poured into molds. The production process for stacked aluminum products is complex, consisting of multiple ground-based equipment on the production line. After production, the stacked aluminum products are bundled into specific quantities. Currently, the industry typically uses manual forklifts to transport the stacked aluminum products to designated locations for stacking. At a time, the forklift can only pick up one bundled stack at a time from the production line. Due to the limited transport distance, manual operation is the only option, making automation difficult, and resulting in low efficiency and poor safety.

[0003] Chinese utility model patent CN220077845U discloses an aluminum plate stacking and handling device, including a base, a Y-axis linear motor, an X-axis linear motor, a Z-axis linear motor, and a handling unit. The second handling mechanism of this utility model includes a second suction cup and a third suction cup that moves up and down relative to the second suction cup, making the height of the gripping mechanism adjustable, facilitating the gripping of irregular aluminum plates. A central gripping plate can assist in gripping the middle position of the aluminum plate. This device handles transport by gripping; however, stacking or bundling aluminum ingots into square stacks may damage their outer surface. Summary of the Invention

[0004] The purpose of this utility model is to provide a convenient and intelligent stacking and handling device that can transport bundled stacks of ...

[0005] The technical solution of this utility model is as follows: A device for synchronously forking and transporting aluminum ingot stacks includes a movable support, on which a rotating frame is provided. Several sets of independent lifting drive devices and guide lifting mechanisms are installed on the rotating frame. A set of rotating drive mechanisms is provided at the side end of the rotating frame. Forks are connected to the bottom of each set of guide lifting mechanisms. The lifting drive devices are used to drive the corresponding guide lifting mechanisms to perform lifting movements. The rotating drive mechanisms are used to drive the rotating frame to drive all guide lifting mechanisms to achieve rotational positioning at any angle.

[0006] Preferably, a slewing bearing is installed on the upper end face of the movable support, and the rotating frame is coaxially arranged above the slewing bearing and can rotate around its axis; three sets of lifting drive devices distributed in an isosceles triangle are provided on the upper end of the rotating frame.

[0007] Preferably, three sets of guide lifting mechanisms are arranged side by side along a straight line on the rotating frame, and the lifting drive device is distributed in an isosceles triangle around the three sets of guide lifting mechanisms. Each set of guide lifting mechanisms is connected to a lifting drive device.

[0008] Preferably, the lower end of the guide lifting mechanism is connected to the fork via a flexible connector, the guide lifting mechanism is a multi-stage telescopic sleeve structure, and the fork is a C-shaped fork body.

[0009] Preferably, each lifting drive device can independently drive the corresponding guide lifting mechanism, and can also achieve synchronous driving of the three sets of guide lifting mechanisms.

[0010] Preferably, the rotary drive mechanism drives the rotating frame to rotate, allowing the forks to be adjusted in any angular direction.

[0011] Preferably, the movable support is installed between the two beams of a double-beam trolley or gantry crane via pulleys and a guide rail structure.

[0012] Preferably, the device also integrates an automatic position detection, automatic speed regulation and automatic interlocking protection system, which can realize fully automatic intelligent operation.

[0013] The beneficial effects of this utility model are: 1. This utility model significantly improves handling efficiency and reduces the number of operations. Traditional manual forklifts can only pick up one stack at a time, resulting in numerous handling operations and low efficiency, which cannot meet the needs of continuous large-scale production. Several sets of guide lifting mechanisms and synchronous lifting drives forks arranged side by side on the rotating frame enable the device to pick up multiple aluminum ingots simultaneously in one operation, theoretically increasing the handling efficiency to up to n times the original, and greatly reducing the number of round trips.

[0014] 2. This utility model achieves multi-dimensional flexible positioning and alignment, adapting to complex site layouts. In workshops and storage yards, the stacking directions of piles may differ. Fixed-direction forklift devices require moving the entire machine body for alignment, which is inconvenient and involves complex path planning. This device integrates a slewing bearing and a rotary drive mechanism on a mobile support. This structure allows the rotating frame to drive all forks to achieve 360° arbitrary angle rotation and positioning. This enables the forks to be adjusted to the optimal forklift angle without moving the entire device body, greatly enhancing the equipment's adaptability to site layouts and achieving intelligent and flexible pick-and-place operations.

[0015] 3. This utility model ensures stability and accuracy during the lifting and lowering process, preventing cargo tipping. During lifting, swaying of the forks and cargo, and shifting of the center of gravity, can lead to inaccurate positioning, cargo slippage, and even structural damage. A multi-stage telescopic guide lifting mechanism is employed, ensuring rigidity and stability during lifting and effectively preventing lateral swaying of the forks. The "U"-shaped design of the forks ensures that the center of gravity of the lifted stack remains on the vertical centerline of the guide lifting mechanism, preventing tilting of the mechanism and cargo swaying due to center of gravity shift. The flexible connection at the base of the guide lifting mechanism and the rotating frame provides cushioning, preventing rigid deformation due to accidental lateral impacts and protecting the equipment.

[0016] 4. This invention enhances the functionality and adaptability of the equipment. Different operating conditions may require single-stack operation or adjustment of specific fork heights to accommodate uneven ground or stack shapes. Multiple independently driveable lifting drive devices are provided. This structure gives the equipment greater flexibility; operators can choose to operate one, two, or three sets simultaneously as needed. It can handle the special requirements of single-stack handling and also adapt to uneven handling surfaces by independently fine-tuning the height of each fork, thus enhancing the equipment's overall adaptability to various operating conditions.

Detailed Implementation

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. However, it should not be understood that the scope of the subject matter of the present utility model is limited to the following embodiments. Without departing from the above technical ideas of the present utility model, all modifications, substitutions, and changes made according to ordinary technical knowledge and conventional means in the art are included in the scope of the present utility model.

[0020] Referring to Figures 1-4 , the device for synchronously fork-lifting and transporting square stacks of aluminum ingots includes a moving frame 1. The moving frame 1 is of an H-shaped frame structure and is arranged between the double beams of a double-girder overhead crane or a gantry crane through a sliding connection. A slewing bearing 3 and a rotating frame 4 are successively installed on the moving frame 1. The rotating frame 4 can rotate around the axis of the slewing bearing 3. Three sets of lifting drive devices 5 with independent drive functions are provided on the rotating frame 4. A guiding lifting mechanism 6 and a fork 7 are provided below each set of lifting drive devices 5. The guiding lifting mechanism 6 and the fork 7 can be driven individually or synchronously. When it is necessary to transport the square stack 8, the guiding lifting mechanism 6 is lowered by the lifting drive device 5, and the direction of the fork 7 for fork-lifting the square stack (8) is adjusted at any angle by driving the rotating frame 4 to rotate through the rotation drive mechanism 2. This device can automatically control the actions of the whole device in multiple dimensions such as horizontal, vertical, height, and angle, so as to realize the functions of automatically hanging, unloading, and transporting square stacks 8 at any position and angle on the ground.

[0021] To facilitate compressing the overall external dimension of the rotation drive mechanism 2, the three sets of lifting drive devices 5 are arranged in a "pin" shape in the plane orientation. The lifting drive devices 5 can be selected to work individually, or any two combinations can be selected, or three can work synchronously, and can adjust the height and direction of the square stack transportation as required, and can fork up and put down the square stack placed on the ground.

[0022] To facilitate taking and placing the neatly arranged square stacks on the ground, the three sets of guiding lifting mechanisms 6 are arranged side by side in a straight line; the guiding lifting mechanism 6 adopts a sleeve telescopic structure to ensure that it remains rigid and does not freely sway during the movement process, and the height position adjustment is realized by being driven by the lifting drive device 5; the guiding lifting mechanism 6 and the rotating frame 4 are flexibly connected at the root, effectively avoiding the rigid deformation failure caused by accidental lateral impact.

[0023] The fork 7 is installed at the bottom of the guiding lifting mechanism 6 and moves up and down with the guiding lifting mechanism 6; the fork 7 is of a "C" structure to ensure that the center of gravity of the square stack carried below is on the vertical center line of the guiding lifting mechanism 6, avoiding the phenomenon of mechanism skew and side deviation caused by the center of gravity offset, and preventing the square stack above the fork from swaying during the start-stop operation.

[0024] This device can combine automatic control means such as automatic position detection, automatic speed regulation, and automatic interlock protection to realize the full-automatic and intelligent operation of the device.

[0025] This device is designed for handling and stacking products in bundles, including but not limited to, square stacks. It is a specialized device for moving square stacks of products to storage yards or transporting them by flatbed truck.

[0026] This utility model relates to the handling of stacked and bundled square stacks of aluminum ingots (square bars, flat ingots) within the aluminum industry's production processes. It enables the transport of bundled square stacks from workshops, warehouses, and storage yards to various production stations, automatically lifting and lowering them as needed, and interlocking with ground equipment at each station. This improves work efficiency while significantly reducing safety hazards and manual labor intensity.

[0027] A large aluminum plant produces 500,000 tons of molten aluminum annually, with 330 working days per year. This translates to a daily output of at least 1,500 tons of molten aluminum, corresponding to 1,500 tons of stacked aluminum products. Each stack weighs approximately 1.1 tons, resulting in 1,360 stacks produced daily. The stacks are manually moved from the production line to the ground using forklifts, with each forklift handling only one bundle at a time, requiring at least 1,360 stack handling operations per day. Transferring and unloading between workstations within the workshop are also done manually on-site. This labor-intensive process poses safety hazards, and forklift operators are highly susceptible to visual fatigue during continuous production, leading to accidents. To improve operational efficiency, reduce on-site manpower, and enhance system safety, the plant decided to mechanize and automate its stacking production process.

[0028] The device for synchronously forklifting and transporting three stacks of aluminum ingots (square bars and flat ingots) using this invention reduces the number of times the stacks are handled per day to only one-third of the number handled manually, while also saving on labor and energy costs associated with manual forklifts. This device can be combined with automatic position detection, automatic speed adjustment, and automatic interlocking protection to achieve fully automated and intelligent operation; enabling unmanned production, significantly improving production efficiency and enhancing system safety. The total investment for the system upgrade is only a few million yuan. Taking an aluminum plant with an annual production capacity of 500,000 tons of molten aluminum as an example, the number of handling operations performed by this device increases with production capacity, and decreases with decreasing production capacity.

[0029] This technology eliminates all the shortcomings of traditional methods. It can achieve automated transfer of square stacks of products with a relatively simple mechanism, and can also adjust the hanging height of the products as needed. All operation control functions are realized on the main body of the device for synchronously picking and transporting three stacks of aluminum ingots (square bars and flat ingots). It does not require a complicated system of machinery and structure, saves investment, has high efficiency, low failure rate, and strong safety. Moreover, the independent modular handling device can be added or removed as needed. If individual lifting mechanisms malfunction during the production process, they can be easily moved or removed for maintenance without affecting the system's production operation.

[0030] The above provides a detailed description of the device for synchronously forking and transporting aluminum ingot stacks provided by this utility model. Specific examples have been used to illustrate the structure and working principle of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
