Description

Technical Field

[0001] This invention relates to the field of battery pack transfer technology, and more particularly to a heavy-duty truck battery pack transfer application using a lifting forklift. Background Technology

[0002] As the global mining industry shifts towards green and low-carbon practices, pure electric heavy-duty trucks have become a significant industry trend. However, existing pure electric heavy-duty trucks typically have swappable battery packs. These top-mounted battery packs are enormous, exceeding 2 meters in height and weighing approximately 3000 kilograms. With the lifting point at the top, they require specialized machinery for hoisting and movement. Therefore, battery swapping for existing heavy-duty trucks requires specialized battery swapping stations. For locations where such stations cannot be built, but where trucks need battery swapping, the process is quite cumbersome. While forklifts are commonly used industrial handling vehicles, widely applied in loading, unloading, moving, and short-distance transportation, making this a viable option...

[0003] However, existing technologies still have the following drawbacks or problems: First, the forks of existing forklifts are usually fixed, and the fork structure is relatively simple. The two forks cannot move horizontally, causing the battery pack to be vertically lifted or lowered after the forklift inserts its forks into the lifting frame at the top of the battery pack. When the forklift then moves to transport the battery pack, the battery pack on the forks is prone to displacement due to shaking, making subsequent installation inconvenient and unsafe. Second, the forks of existing forklifts are located at the bottom of the forklift mast, resulting in a low lifting point. Since the battery pack is tall and located above the heavy truck, the lifting point requirement is very high, making it difficult for the forklift to lift the battery pack. Therefore, developing a device that can safely lift and transport battery packs without the need for specialized lifting machinery is one of the technical challenges that needs to be solved. Summary of the Invention

Multiple second proximity switches are fixedly installed on the outer wall of each fixing seat at equal intervals. A cable tray is fixedly installed on the upper surface of the front fork.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, through the design of the outer mast, clamping mechanism, first fork, and second fork, the forklift body moves the first fork and second fork directly above the battery pack. Then, the forklift body can drive the first fork and second fork downward through the outer mast until the hook moves to the inside of the battery pack lifting frame. The clamping mechanism is activated, which drives the first fork and second fork to move to both sides, so that the hook is inserted below the battery pack lifting frame. At this time, the forklift drives the first fork and second fork upward through the outer mast, so that the battery pack is separated from the bottom pallet, thereby completing the lifting of the battery pack. Moreover, the stability during lifting and transportation is strong, and the battery pack will not be displaced due to shaking, nor will it slip off.

[0016] 2. In this invention, the positions of the first fork and the second fork can be accurately observed through the first camera and the second camera. When the positions of the first fork and the second fork are offset, the outer mast is pushed to move. At this time, the outer mast drives the first fork and the second fork to move horizontally through the clamping mechanism, ensuring that the first fork and the second fork are directly above the battery pack lifting frame, without the need for the forklift body to move.

[0017] 3. In this invention, the deflection angle of the support frame can be detected by an electronic level, which can drive the support frame to swing. The support frame can drive the first fork and the second fork to swing through the lifting mechanism, the translation mechanism, the outer mast, and the clamping mechanism, thereby adjusting the tilt angle of the first fork and the second fork.

[0018] 4. In this invention, the front fork is set on the top of the support column, which improves the lifting point of the forklift and makes operation more convenient. In addition, through the design of multiple sets of second proximity switches, when the second proximity switch is close to the battery pack shell, the second proximity switch can realize signal feedback, which makes it convenient for the operator to accurately determine the position of the first fork, thereby facilitating the operator to accurately position the first fork.

[0019] 5. In this invention, through the design of the mounting base and rubber wheel, when the first fork moves downward, the rubber wheel can contact the H-shaped reinforcing member of the battery pack lifting frame first, which can prevent the hook from making hard contact with the battery pack shell when the first fork descends, thereby preventing damage to the battery pack. The rubber wheel can also protect the second proximity switch. Attached Figure Description

[0055] In the above technical solution, the cable tray is used to install and discharge the wires connected to the second proximity switch 21; through the design of multiple sets of second proximity switches 21, when the second proximity switch 21 is close to the battery pack shell, the second proximity switch 21 can realize signal feedback, which makes it convenient for the operator to accurately determine the position of the first fork 9, thereby making it convenient for the operator to accurately position the first fork 9.

[0056] It is worth mentioning that the forklift lifting device of this utility model is mainly used for lifting the battery pack of new energy heavy trucks, and is mainly used for replacing the battery pack of new energy heavy trucks, thereby realizing the rapid battery swapping of new energy heavy trucks. For details, please refer to patent announcement number CN223278961U. The specific structure of its battery pack can also be referred to patent application number 202620093603.9. It is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.

[0057] The specific usage and function of this embodiment are as follows: When the present invention is used, the lifting forklift moves to one side of the battery pack. In the initial state, the first fork 9 and the second fork 10 move to the top of the battery pack and are close to each other, ensuring that the first fork 9 and the second fork 10 can be smoothly extended into the inside of the lifting frame at the top of the battery pack. It is worth mentioning that the electronic level 14 can detect the deflection angle of the support frame 3, and start the first hydraulic cylinder 202. The first hydraulic cylinder 202 can drive the support frame 3 to swing through the second connecting seat 203. The support frame 3 can drive the first fork 9 and the second fork 10 to swing through the lifting mechanism 4, the translation mechanism 5, the outer mast 6, and the clamping mechanism 7, thereby adjusting the tilt angle of the first fork 9 and the second fork 10. The positions of the first fork 9 and the second fork 10 can be accurately observed through the first camera 15 and the second camera 17. When the positions of the first fork 9 and the second fork 10 are deviated, the third hydraulic cylinder 507 is activated. The third hydraulic cylinder 507 pushes the outer mast 6 to move. At this time, the outer mast 6 drives the first fork 9 and the second fork 10 to move horizontally through the clamping mechanism 7, ensuring that the first fork 9 and the second fork 10 are directly above the battery pack lifting frame, without the need for the forklift body 1 to move. Start the second hydraulic cylinder 401. The second hydraulic cylinder 401 drives the lifting frame 403 to move downward through the horizontal plate 402. The lifting frame 403 drives the outer mast 6 to move downward through the translation mechanism 5. The outer mast 6 drives the first fork 9 and the second fork 10 to move downward until the hook 903 moves to the inside of the battery pack lifting frame. Start the fourth hydraulic cylinder 701 and the fifth hydraulic cylinder 703. The fourth hydraulic cylinder 701 pushes the first moving block 702 to move, and the fifth hydraulic cylinder 703 pushes the second moving block 704 to move. The first moving block 702 and the second moving block 704 drive the first fork 9 and the second fork 10 to move to both sides through the upper slider 705 and the second mounting plate 706, so that the hook 903 is inserted under the battery pack lifting frame. Then, the second hydraulic cylinder 401 is activated. The second hydraulic cylinder 401 drives the lifting frame 403 to move upward through the horizontal plate 402. The lifting frame 403 drives the outer mast 6 to move upward through the translation mechanism 5. The outer mast 6 drives the first fork 9 and the second fork 10 to move upward, so that the battery pack is separated from the bottom pallet, thereby completing the hoisting of the battery pack. The forklift body 1 is then activated to complete the transfer of the battery pack.
