Description

Technical Field

[0001] This disclosure relates to the field of lifting devices for lithium battery packs, and more specifically, to a lifting device compatible with multiple lithium battery packs. Background Technology

[0002] At the finished product assembly line station for lithium-ion battery packs, technicians need to use lifting equipment to transport the finished packs from the production line to the finished product rack. The external dimensions of the various finished packs on the production line are not entirely the same. Furthermore, the lifting points for each finished pack also differ. In addition, the net height of the new energy production line is generally around 3.5 meters, resulting in limited space in the Z-axis direction when lifting finished packs. Existing lifting equipment has poor adaptability and can only meet the lifting and transfer needs of a single lithium-ion battery pack. Summary of the Invention

[0003] To overcome the problem that existing lifting tools have poor adaptability and can only meet the lifting and transportation needs of a single lithium battery pack, this utility model provides a lifting tool that is compatible with multiple lithium battery packs.

[0004] To achieve the above objectives, this disclosure provides a lifting device compatible with various lithium battery packs, comprising:

[0005] Two first crossbeams are spaced apart along a first direction;

[0006] Four longitudinal beams are spaced apart along the second direction and are respectively connected to the top of the two first transverse beams;

[0007] A connecting plate is installed at the bottom of the two middle longitudinal beams, and the top of the connecting plate is used to connect to the telescopic boom of the crane's rigid boom.

[0008] Four first linear modules are installed one-to-one with the four longitudinal beams;

[0009] Four second crossbeams, two of which are installed between two longitudinal beams in one group via two first straight modules at their ends, and the other two second crossbeams are installed between two longitudinal beams in another group via two first straight modules.

[0010] Four second linear modules are installed one-to-one with the four second crossbeams; and

[0011] Four hooks are provided, one for each of the four second linear modules. One end of each hook is connected to the slider of the second linear module, and the other end is used to insert into the mounting hole of the lithium battery pack.

[0012] Optionally, the lifting device further includes two first crossbeams, four first crossbeams are spaced apart along a second direction, and four longitudinal beams are respectively connected to the top of the four first crossbeams;

[0013] The connecting plate is installed on the two first crossbeams in the middle.

[0014] Optionally, the second crossbeam is an octagonal tube;

[0015] The hook is connected to the slider of the second linear module via a connector. The connector has a through hole, and a pin is inserted into the through hole and one of the multiple insertion holes of the octagonal tube.

[0016] Optionally, the pin is an indexing pin.

[0017] Optionally, a thrust bearing is installed on the connector, and the hook is connected to the connector via the thrust bearing.

[0018] Optionally, the lifting device further includes four speed-differential fall arresters, the top of which is attached to the fixed arm of the crane's rigid boom, and the bottom of which is attached to the two outer longitudinal beams respectively. The telescopic arm of the crane's rigid boom is slidably connected to the fixed arm.

[0019] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0020] The crane's rigid boom moves the connecting plate to directly above the lithium battery pack. Then, the telescopic boom extends, allowing the lifting device to move downwards. Next, the first and second linear modules move, enabling the hook to move in a three-dimensional coordinate system. This allows one end of the hook to insert into the mounting hole of the lithium battery pack, ensuring the hook can move according to changes in the outer dimensions of the lithium battery pack and the position of the lifting point. This ensures the lifting device is compatible with the lifting and transport of various lithium battery packs. Because it is installed at the bottom of the two intermediate longitudinal beams, the Z-axis movement space of the lifting device is relatively large. Attached Figure Description

[0023] The specific embodiments of this disclosure 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 this disclosure.

[0024] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing orientations of the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this disclosure are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0025] Please see Figure 1 This disclosure provides a lifting device compatible with various lithium battery packs 1. The lithium battery pack 1 has four mounting holes. The lithium battery pack 1 is rectangular and is based on existing technology, so it will not be described in detail here. The lifting device includes two first crossbeams 110, four longitudinal beams 200, a connecting plate 300, four first linear modules 410, four second crossbeams 120, four second linear modules 420, and four hooks 510. The two first crossbeams 110 are spaced apart along a first direction. The four longitudinal beams 200 are spaced apart along a second direction and are respectively connected to the top of the two first crossbeams 110. The first direction is perpendicular to the second direction. The connecting plate 300 is installed at the bottom of the two middle longitudinal beams 200, and the top of the connecting plate 300 is used to connect to the telescopic boom 2 of the crane's rigid boom. The four first linear modules 410 are installed one-to-one with the four longitudinal beams 200. Two second crossbeams 120 are installed at both ends between two longitudinal beams 200 in one group via two first linear modules 410. Two other second crossbeams 120 are installed between two longitudinal beams 200 in another group via two first linear modules 410. Four second linear modules 420 are installed correspondingly to four second crossbeams 120. Four hooks 510 are installed correspondingly to four second linear modules 420; one end of each hook 510 is connected to a slider of a second linear module 420, and the other end is inserted into a mounting hole of the lithium battery pack 1.

[0026] Understandably, the first crossbeam and longitudinal beam are first installed as a whole, and then installed with the second crossbeam. The crane's rigid boom moves the connecting plate 300 to directly above the lithium battery pack 1. Then, the telescopic boom 2 extends, allowing the lifting device to move downwards. Next, the first linear module 410 and the second linear module 420 move, allowing the hook 510 to move in a three-dimensional coordinate system. This allows one end of the hook 510 to be inserted into the hook hole of the lithium battery pack 1, ensuring that the hook 510 can move according to changes in the outer contour dimensions of the lithium battery pack 1 and the position of the lifting point, thus ensuring that the lifting device is compatible with the lifting and transportation of various lithium battery packs 1. Because it is installed at the bottom of the two intermediate longitudinal beams 200, the Z-axis movement space of the lifting device is relatively large.

[0027] In one implementation, please refer to Figure 1 The lifting device also includes two first crossbeams 110, and four first crossbeams 110 are spaced apart along the second direction. Four longitudinal beams 200 are respectively connected to the top of the four first crossbeams 110. A connecting plate 300 is installed on the two middle first crossbeams 110 to ensure that the connecting plate 300 can be stably connected to the first crossbeams 110, thereby ensuring that the crane can drive the lifting device to move stably.

[0028] In one implementation, please refer to Figure 1 The second crossbeam 120, the first crossbeam 110, and the longitudinal beam 200 are all octagonal tubes, connected to adjacent octagonal tubes by octagonal tube connecting accessories. The hook 510 is connected to the slider of the second linear module 420 via a connector 520. The connector 520 has a through hole, and a pin 600 is inserted into the through hole and one of the multiple insertion holes of the octagonal tube. The second crossbeam 120 adopts an octagonal tube design, which provides more stable support and stronger torsional resistance, ensuring the stability and safety of the entire lifting device during use. When one end of the hook 510 is inserted into the hook hole of the lithium battery pack 1, the pin 600 is inserted into the through hole and one of the multiple insertion holes to prevent the hook 510 from moving relative to the second linear module 420 during the transfer of the lithium battery pack 1, ensuring the stability of the lithium battery pack 1 during transfer.

[0029] In one implementation, please refer to Figure 1 The 600mm pin is an indexing pin. The indexing pin achieves precise positioning and adjustment of the workpiece or component through its telescopic movement.

[0030] In one implementation, please refer to Figure 1 A thrust bearing is installed on the connector 520, and the hook 510 is connected to the connector 520 through the thrust bearing, so that the hook 510 can be flexibly and conveniently inserted into the hanging hole of the lithium battery pack 1.

[0031] In one implementation, please refer to Figure 1The lifting device also includes four differential fall arresters 700. The top of each differential fall arrester 700 is attached to the fixed arm of the crane's rigid boom, and the bottom of each is attached to two outer longitudinal beams 200. The telescopic boom 2 of the crane's rigid boom is slidably connected to the fixed arm. Its function is that when the lifting device suddenly falls, the safety belt of the differential fall arrester 700 can immediately pull the lifting device to prevent it from continuing to fall; at the same time, the buffer of the differential fall arrester 700 can reduce the impact force of the fall. When the lifting device is raised and lowered with the crane, the safety belt of the differential fall arrester 700 can move with the lifting device. The differential fall arrester 700 is existing technology and will not be described in detail here.

[0032] In one implementation, please refer to Figure 1 A hook 510 storage attachment point is connected to the longitudinal beam 200. The hook 510 storage attachment point is used to hang unused hooks 510.

[0033] In one implementation, please refer to Figure 1 Several insulating anti-collision blocks are connected to the outer ends of the four first crossbeams 110. The insulating anti-collision blocks can prevent the main frame of the lifting device from rubbing against the lithium battery pack 1, and can also provide insulation in the event of rubbing.

[0034] In one implementation, please refer to Figure 1 Each of the two outermost first crossbeams 110 is connected to an insulated handle. The insulated handles provide grip for the operator and also offer some insulation. Each of the two outermost first crossbeams 110 is connected to a remote control holder. The remote control holder is used by the operator to easily place and retrieve the crane's remote control.

Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of this invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
