[0005] This application provides a lifting tool that can quickly switch between different lifting functions without changing equipment, thereby improving on-site operation efficiency and operational safety.

[0006] This application provides a lifting fixture for lifting CTP battery packs, the CTP battery packs including a frame and at least two layers of liquid cooling plates, and the lifting fixture includes:

[0007] The mounting bracket has a first mounting position and a second mounting position;

[0008] A lifting device assembly is provided on the mounting frame. The lifting device assembly includes a first lifting device and a second lifting device. The first lifting device is provided at a first mounting position and is used to lift the liquid cooling plate and stack the liquid cooling plate onto the frame.

[0009] The second lifting device is located at the second installation position and is used to lift the frame to move the CTP battery pack.

[0010] The beneficial effects of this application are: by setting up the lifting tooling and integrating the first and second lifting tools on the same mounting frame, the space occupied is reduced, which can better meet the assembly and movement of CTP battery packs, reduce the number of operation steps and time for operators. After the CTP battery pack is sealed, it also needs internal transportation and logistics storage, which allows operators to quickly switch the lifting tool functions without changing equipment or readjusting the installation position, thereby improving on-site operation efficiency, reducing the risk of operational errors, and improving the overall operation safety.

[0011] In some alternative implementations, there are multiple lifting assemblies located around the mounting frame.

[0012] It should be noted that multiple lifting assemblies are distributed around the mounting frame, which can distribute the load more evenly, reduce the stress on individual lifting assemblies, and improve the stability and durability of the overall structure. By arranging them around the frame, the lifting fixtures can better maintain balance during lifting and movement, reducing the risk of tilting or swaying and ensuring operational safety.

[0013] In some alternative embodiments, the first lifting device includes a first lifting ring, a first connecting strap, and a first hook. The first lifting ring is located at a first mounting position, the first hook engages with the liquid cooling plate, and the first connecting strap is used to movably connect the first lifting ring and the first hook.

[0014] It should be noted that the first lifting ring is located in the first installation position, which facilitates quick installation and disassembly of the lifting equipment, reduces preparation time, and improves work efficiency; the first hook engages with the liquid cooling plate, ensuring the stability and safety of the liquid cooling plate during the lifting process and preventing slippage or accidental disengagement; the first connecting strap is used to connect the first lifting ring and the first hook, providing a flexible connection method that allows it to adapt to different height and angle requirements during the lifting process, improving operational flexibility.

[0015] In some alternative embodiments, the first hook includes a first body and a hook assembly, the first body being movably disposed on a first connecting belt, and the hook assembly being disposed on the first body;

[0016] The hook is a bent part, and the hook extends toward the liquid cooling plate to engage with the liquid cooling plate.

[0017] It should be noted that the first body is movably located on the first connecting belt, which allows the hook to be flexibly adjusted within a certain range to adapt to liquid cooling plates of different sizes and positions, increasing operational flexibility; the hook is designed as a bending component, which can closely fit the edge of the liquid cooling plate or a specific structure to achieve a stable grip and prevent slippage during lifting.

[0018] In some alternative embodiments, the second lifting device includes a second lifting ring, a second connecting strap, and a second hook. The second lifting ring is located at a second mounting position, the second hook is engaged with the frame, and the second connecting strap is used to movably connect the second lifting ring and the second hook.

[0019] It should be noted that the second lifting device provides an efficient, safe, and flexible solution for lifting the frame. Combined with the first lifting device, the entire lifting fixture can effectively handle the lifting and moving needs of CTP battery packs.

[0020] In some alternative embodiments, the second hook includes a second body and a locking element, the second body being movably disposed on the second connecting belt, and the locking element being disposed on the second body to lock with the frame.

[0021] It should be noted that the design of the locking mechanism allows the second hook to be securely locked to the frame, ensuring the stability of the frame during lifting, reducing the risk of swaying and tilting, preventing accidental disengagement during lifting and movement, and enhancing operational safety.

[0022] In some alternative embodiments, the second hook further includes a positioning post disposed on the second body and extending into a positioning hole in the frame.

[0023] It should be noted that the positioning post design allows the second hook to precisely align with the positioning hole on the frame, ensuring the lifting device is locked in the correct position and improving operational accuracy. Furthermore, the positioning post extending into the positioning hole of the frame provides additional support and stability, reducing potential swaying and displacement during lifting.

[0024] In some alternative embodiments, the locking element includes a locking part and a rotating part, a mounting hole is provided on the second body, the locking part passes through the mounting hole, and the first end of the locking part extends into the locking hole of the frame;

[0025] The rotating part is rotatably located at the second end of the locking part and is configured to adjust the locking amount between the locking part and the locking hole by rotating the rotating part.

[0026] It should be noted that the rotating part is designed to allow operators to adjust the locking amount between the locking part and the locking holes in the frame by rotating it. This adjustability allows the spreader to adapt to frames of different thicknesses and materials, improving operational flexibility; in addition, by precisely adjusting the locking amount, the stability of the spreader during lifting is ensured, reducing the risk of accidental loosening or disengagement, and improving overall operational safety.

[0027] In some alternative embodiments, the mounting bracket includes a crossbeam, a first mounting beam, and a second mounting beam, wherein the length of the first mounting beam is greater than the length of the second mounting beam;

[0028] There are at least two first mounting beams and at least two second mounting beams, with at least two first mounting beams and at least two second mounting beams connected together, and a crossbeam installed between the two first mounting beams.

[0029] It should be noted that the combined design of the first and second mounting beams provides a robust frame structure. The length of the first mounting beam is greater than that of the second mounting beam to provide a larger support surface and better force distribution, thereby enhancing the overall structural stability.

[0030] In some alternative embodiments, the mounting bracket may further include a plurality of reinforcing plates disposed between adjacent first and second mounting beams.

[0031] It should be noted that the reinforcing plate is placed between the adjacent first and second mounting beams, providing additional support and reinforcement, which significantly improves the overall structural strength and durability of the mounting frame.

[0032] This application provides a lifting fixture for lifting CTP battery packs. The CTP battery pack includes a frame and at least two layers of liquid cooling plates. The lifting fixture includes: a mounting frame having a first mounting position and a second mounting position; a lifting assembly disposed on the mounting frame, the lifting assembly including a first lifting tool and a second lifting tool. The first lifting tool is disposed at the first mounting position and is used to lift the liquid cooling plates and stack the liquid cooling plates onto the frame; the second lifting tool is disposed at the second mounting position and is used to lift the frame to move the CTP battery pack.

[0033] By setting up lifting fixtures and integrating the first and second lifting fixtures on the same mounting frame, the space occupied is reduced, which can better meet the assembly and movement of CTP battery packs. This reduces the number of operation steps and time for operators. After the CTP battery packs are sealed, they also need to be transported and stored internally. This allows operators to quickly switch the function of the lifting fixtures without changing equipment or readjusting the installation position, thereby improving on-site operation efficiency, reducing the risk of operational errors, and improving the overall safety of operation.

[0063] Currently, the production process of CTP battery packs requires the use of two sets of lifting tools for assembly or handling, making the entire assembly process quite complex. Furthermore, the lifting tools are prone to detachment, which can easily lead to safety risks.

[0064] The lifting fixture proposed in this application, by setting up the lifting fixture and integrating the first and second lifting fixtures on the same mounting frame, reduces the space occupied and can better meet the assembly and movement of CTP battery packs. It reduces the number of operation steps and time for operators. After the CTP battery packs are sealed, they also need to be internally transported and stored in logistics. This allows operators to quickly switch the function of the lifting fixture without changing equipment or readjusting the installation position, thereby improving on-site operation efficiency, reducing the risk of operational errors, and improving the overall safety of operation.

[0065] The lifting tooling provided in this application will be described in detail below with reference to specific embodiments.

[0066] Figure 1 This is a schematic diagram of the assembly of the first lifting device and the CTP battery pack in the lifting fixture of this application embodiment. Figure 2 for Figure 1 A magnified view of a section at point I. Figure 3 for Figure 1 A magnified view of a section at point II.

Figure 5 This is a schematic diagram illustrating the assembly of the second lifting device and the CTP battery pack in the lifting fixture of this application embodiment. Figure 6 for Figure 5 A magnified view of section III in the middle.

[0067] like Figures 1 to 6 As shown in the embodiment of this application, a lifting fixture 100 is proposed for lifting a CTP battery pack 200. The CTP battery pack 200 includes a frame 211 and at least two layers of liquid cooling plates 220. The lifting fixture 100 includes:

[0068] Mounting bracket 130 has a first mounting position and a second mounting position;

[0069] The lifting assembly is provided on the mounting frame 130. The lifting assembly includes a first lifting device 110 and a second lifting device 120. The first lifting device 110 is provided at a first mounting position. The first lifting device 110 is used to lift the liquid cooling plate 220 and stack the liquid cooling plate 220 onto the frame 211.

[0070] The second lifting device 120 is located at the second installation position and is used to lift the frame 211 to move the CTP battery pack 200.

[0071] In this embodiment of the application, the CTP battery pack 200 includes at least two liquid cooling plates 220 and at least two battery modules 230. Each liquid cooling plate 220 corresponds to one battery module 230. All parts of the battery module 230 can be cooled evenly and quickly, which improves the heat dissipation performance of the battery module 230, extends the service life of the internal cells, and improves the range performance of the CTP battery pack 200.

[0072] In some embodiments, at least two liquid cooling plates 220 may include a first liquid cooling plate 221 and a second liquid cooling plate 222, wherein at least one of the first liquid cooling plate 221 and the second liquid cooling plate 222 is a profile liquid cooling plate 220.

[0073] It should be noted that the structural design of the profile liquid cooling plate 220 can provide additional mechanical strength and rigidity, enhance the structural stability of the entire CTP battery pack 200, and reduce deformation or damage caused by vibration or impact.

[0074] In some embodiments, at least two battery modules 230 may include a first battery module 231 and a second battery module 232, wherein the first battery module 231 is located on a first liquid cooling plate 221 and the second battery module 232 is located on a second liquid cooling plate 222.

[0075] In some embodiments, the CTP battery pack 200 further includes a housing 210, with a first liquid cooling plate 221 and a second liquid cooling plate 222 spaced apart vertically in the thickness direction of the housing 210, that is, the first liquid cooling plate 221 is located on top and the second liquid cooling plate 222 is located on the bottom.

[0076] In some embodiments, the housing 210 includes a frame 211 and a cover 212, the cover 212 covering the frame 211 to accommodate at least two liquid cooling plates 220 and at least two battery modules 230.

[0077] The frame 211 provides a stable foundation for mounting the first liquid cooling plate 221 and the second liquid cooling plate 222, the first battery module 231, and the second battery module 232. By fixing the first liquid cooling plate 221 and the second liquid cooling plate 222 to the frame 211, the structural stability of the entire CTP battery pack 200 can be improved, ensuring that the first liquid cooling plate 221 and the second liquid cooling plate 222 maintain good position and contact during operation.

[0078] In some embodiments, the lid 212 is C-shaped and adopts a semi-enclosed structure, eliminating the side borders, achieving a lightweight design while reducing costs and increasing efficiency.

[0079] It should be noted that the lifting fixture 100 provided in this application embodiment is used for lifting, assembling or transporting CTP battery pack 200. The first lifting fixture 110 is used to lift the liquid cooling plate 220 located on the upper layer, that is, to lift the first liquid cooling plate 221.

[0080] It should be noted that the entire lifting process of the lifting fixture 100 provided in this application embodiment is as follows: the second liquid cooling plate 222 is integrated with the frame 211 in advance on the production line, and then the second battery module 232 is placed on the second liquid cooling plate 222; next, the first battery module 231 on another production line is installed on the first liquid cooling plate 221, and the first liquid cooling plate 221 is lifted by the first lifting fixture 110, and then the first liquid cooling plate 221 and the first battery module 231 are both moved to the frame 211 by the first lifting fixture 110 and installed on the frame 211, and stacked on the second liquid cooling plate 222; finally, the box cover 212 is installed. After the box cover 212 is installed, it means that the entire CTP battery pack 200 has been installed. The frame 211 is then lifted by the second lifting fixture 120 to transport the entire CTP battery pack 200 to the next production line or to other places.

[0081] By setting up the above-mentioned lifting tool 100 and integrating the first lifting tool 110 and the second lifting tool 120 on the same mounting frame 130, the space occupied is reduced, which can better meet the assembly and movement of the CTP battery pack 200, and reduce the number of operation steps and time for operators. After the CTP battery pack 200 is sealed, it also needs to be internally transported and stored in logistics. This allows operators to quickly switch the lifting tool functions without changing equipment or readjusting the installation position, thereby improving on-site operation efficiency, reducing the risk of operational errors, and improving the overall safety of operation.

[0082] In some alternative implementations, there are multiple lifting assemblies located around the mounting frame 130.

[0083] It should be noted that multiple lifting assemblies are distributed around the mounting frame 130, which can distribute the load more evenly, reduce the stress on individual lifting assemblies, and improve the stability and durability of the overall structure. With the arrangement around the perimeter, the lifting fixture 100 can better maintain its balance during lifting and movement, reducing the risk of tilting or swaying and ensuring the safety of operation.

[0084] In some embodiments, the lifting device assembly consists of four sets, meaning that there are four first lifting devices 110 and four second lifting devices 120, all distributed around the mounting frame 130.

[0085] In some embodiments, there are four first mounting positions to match four first spreaders 110, and four second mounting positions to match four second spreaders 120.

[0086] like Figure 1 As shown, in some embodiments, the lifting device assembly further includes a first hook 140 and a second hook 150, both of which are disposed on the mounting bracket 130;

[0087] The first end of the first lifting device 110 is located at the first installation position, and the second end of the first lifting device 110 is hooked to the first hook 140 or the first liquid cooling plate 221.

[0088] The first end of the second lifting device 120 is located at the second installation position, and the second end of the second lifting device 120 is hooked to the second hook 150 or the frame 211.

[0089] It should be noted that when the first lifting device 110 is used, the second lifting device 120 is not used. That is, when the first lifting device 110 is lifting the first liquid cooling plate 221, the second end of the second lifting device 120 is hooked to the second hook 150 and does not participate in the lifting.

[0090] Correspondingly, when the second lifting device 120 is on the lifting frame 211, the second end of the first lifting device 110 is hooked to the first hook 140 and does not participate in the lifting.

[0091] Figure 7 This is a schematic diagram of the lifting tooling according to an embodiment of this application, as shown below. Figures 1 to 7 As shown, in some optional embodiments, the first lifting device 110 includes a first lifting ring 111, a first connecting strap 112 and a first hook 113. The first lifting ring 111 is located at a first mounting position, the first hook 113 is engaged with the liquid cooling plate 220, and the first connecting strap 112 is used to movably connect the first lifting ring 111 and the first hook 113.

[0092] It should be noted that the first lifting ring 111 is located in the first installation position, which facilitates quick installation and disassembly of the lifting equipment, reduces preparation time, and improves work efficiency; the first hook 113 is engaged with the liquid cooling plate 220, ensuring the stability and safety of the liquid cooling plate 220 during the lifting process and preventing slippage or accidental disengagement; the first connecting strap 112 is used to connect the first lifting ring 111 and the first hook 113, providing a flexible connection method, which allows it to adapt to different height and angle requirements during the lifting process and improves operational flexibility.

[0093] In some embodiments, the use of the first connecting strap 112 can provide shock absorption and cushioning effects to a certain extent, reducing the impact on the first liquid cooling plate 221 and protecting the integrity of the suspended object.

[0094] In some embodiments, the first lifting ring 111 is movably disposed in the first mounting position, and the first lifting ring 111 can be detachably installed in the first mounting position by means of bolts or fasteners.

[0095] Figure 8 for Figure 7 A magnified view of a section at point IV. Figure 9 for Figure 7 A magnified view of the middle V section. Figure 10 This is a cross-sectional view of the assembly of the first lifting device and the first liquid cooling plate in the lifting fixture of this application embodiment.

[0096] like Figures 1 to 10 As shown, in some optional embodiments, the first hook 113 includes a first body 1131 and a hook attachment 1132. The first body 1131 is movably disposed on the first connecting belt 112, and the hook attachment 1132 is disposed on the first body 1131.

[0097] The hook 1132 is a bent part, and the hook 1132 extends toward the liquid cooling plate 220 to engage with the liquid cooling plate 220.

[0098] It should be noted that the first body 1131 is movably mounted on the first connecting belt 112, allowing the hook to be flexibly adjusted within a certain range to adapt to liquid cooling plates 220 of different sizes and positions, thus increasing operational flexibility; the hook 1132 is designed as a bending part, which can closely fit the edge or specific structure of the liquid cooling plate 220 to achieve a stable grip and prevent slippage during lifting.

[0099] It should be noted that the design of the hook 1132 extending toward the liquid cooling plate 220 ensures that the hook 1132 always maintains contact and fixation with the liquid cooling plate 220 during the lifting process, thus enhancing the safety of operation.

[0100] In addition, the design of the bending component allows the hook to adapt to liquid-cooled plates 220 of different shapes and thicknesses, increasing the versatility of the lifting device.

[0101] In some embodiments, the height and length of the hook 1132 are designed according to the height of the lifting hole on the liquid cooling plate 220 so that it will not fall off during the lifting process.

[0102] In some embodiments, the first body 1131 may be an integral structural component or may be formed by combining multiple structural components.

[0103] In some embodiments, the hook 1132 is mounted on the first body 1131 by a pin.

[0104] Among them, the hook part 1132 is a bent part, which can be understood as the extension direction of part of the hook part 1132 is different from the extension direction of another part of the structure. The purpose of this design is to better hook and hold the first liquid cooling plate 221.

[0105] Figure 11 for Figure 7A magnified view of section VI in the middle. Figure 12 for Figure 7 A magnified view of a section at point VII. Figure 13 This is a schematic diagram of the structure of the second hook in the lifting tooling of this application embodiment.

[0106] like Figure 7 , Figures 11 to 13 As shown, in some optional embodiments, the second lifting device 120 includes a second lifting ring 121, a second connecting strap 122, and a second hook 123. The second lifting ring 121 is located in a second mounting position, the second hook 123 is engaged with the frame 211, and the second connecting strap 122 is used to movably connect the second lifting ring 121 and the second hook 123.

[0107] It should be noted that the second lifting device 120 provides an efficient, safe, and flexible solution for lifting the frame 211. Combined with the first lifting device 110, the entire lifting fixture 100 can effectively handle the lifting and movement needs of the CTP battery pack 200.

[0108] Understandably, the second connecting strap 122 is used to connect the second lifting ring 121 and the second hook 123, providing a flexible connection method that allows for adaptation to different height and angle requirements during lifting, thus improving operational flexibility. The second lifting ring 121 is located in the second installation position, facilitating quick installation and disassembly of the lifting equipment, reducing preparation time, and improving work efficiency.

[0109] In addition, the second hook 123 is engaged with the frame 211, ensuring the stability and safety of the frame 211 during the lifting process and preventing slippage or accidental disengagement.

[0110] In addition, by using the second connecting belt 122, the operator can more easily adjust the length and position of the second spreader 120, reducing the difficulty of operation and making it suitable for different operating environments.

[0111] In some alternative embodiments, the second hook 123 includes a second body 1231 and a locking element 1232. The second body 1231 is movably disposed on the second connecting belt 122, and the locking element 1232 is disposed on the second body 1231 to lock with the frame 211.

[0112] It should be noted that the design of the locking fastener 1232 enables the second hook 123 to be securely locked to the frame 211, ensuring the stability of the frame 211 during the lifting process, reducing the risk of swaying and tilting, preventing accidental disengagement during lifting and movement, and enhancing operational safety.

[0113] In some embodiments, the locking fastener 1232 is designed to allow operators to quickly connect or release the second hook 123 to the frame 211, simplifying the operation steps and improving work efficiency; the design of the locking fastener 1232 can adapt to frames 211 of different shapes and structures, increasing the versatility and applicability of the lifting device.

[0114] like Figure 3 , Figure 7 ,as well as Figures 11 to 13 As shown, in some optional embodiments, the second hook 123 further includes a positioning post 1233, which is disposed on the second body 1231 and extends into the positioning hole 2111 of the frame 211.

[0115] It should be noted that the design of the positioning post 1233 allows the second hook 123 to precisely align with the positioning hole 2111 on the frame 211, ensuring that the lifting device is locked in the correct position and improving operational precision. Furthermore, the positioning post 1233 extending into the positioning hole 2111 of the frame 211 provides additional support and stability, reducing potential swaying and displacement during lifting.

[0116] In other words, guided by the positioning column 1233, the operator can more easily align the hook with the frame 211, reducing alignment time and operational difficulty.

[0117] In addition, the presence of the positioning column 1233 effectively prevents the hook from rotating and sliding on the frame 211, ensuring the safety and stability of the hoisting process.

[0118] In some embodiments, there are two positioning posts 1233, which are located on both sides of the locking member 1232.

[0119] like Figure 3 , Figure 7 ,as well as Figures 11 to 13 As shown, in some optional embodiments, the locking member 1232 includes a locking part 12321 and a rotating part 12322. The second body 1231 has a mounting hole, the locking part 12321 passes through the mounting hole, and the first end of the locking part 12321 extends into the locking hole 2112 of the frame 211.

[0120] The rotating part 12322 is rotatably disposed at the second end of the locking part 12321 and is configured to adjust the locking amount between the locking part 12321 and the locking hole 2112 by rotating the rotating part 12322.

[0121] It should be noted that the design of the rotating part 12322 allows the operator to adjust the locking amount between the locking part 12321 and the locking hole 2112 of the frame 211 by rotating it. This adjustability allows the lifting device to adapt to frames 211 of different thicknesses and materials, improving operational flexibility; in addition, by precisely adjusting the locking amount, the stability of the lifting device during the lifting process is ensured, reducing the risk of accidental loosening or disengagement, and improving the overall operational safety.

[0122] Understandably, the locking part 12321 passes through the mounting hole and extends into the locking hole 2112 of the frame 211, providing a stable fixing point to ensure a secure connection between the lifting device and the frame 211 during lifting, preventing it from falling off. The design of the rotating part 12322 makes the locking and releasing process simpler, allowing operators to quickly adjust the locking, reducing preparation time and improving work efficiency.

[0123] It should be noted that, due to the adjustable locking amount, this design can adapt to frames 211 with different locking hole 2112 configurations, increasing the versatility of the lifting device.

[0124] In some embodiments, the locking part 12321 can be a bolt, and the rotating part 12322 facilitates the rotation of the bolt, which is then fixed so that it will not fall off during the lifting process.

[0125] like Figure 1 As shown, in some optional embodiments, the mounting bracket 130 includes a crossbeam 133, a first mounting beam 131 and a second mounting beam 132, wherein the length of the first mounting beam 131 is greater than the length of the second mounting beam 132.

[0126] There are at least two first mounting beams 131 and at least two second mounting beams 132. At least two first mounting beams 131 and at least two second mounting beams 132 are connected together, and a crossbeam 133 is installed between the two first mounting beams 131.

[0127] It should be noted that the combined design of the first mounting beam 131 and the second mounting beam 132 provides a stable frame structure 211. The length of the first mounting beam 131 is greater than the length of the second mounting beam 132 in order to provide a larger support surface and better force distribution, thereby enhancing the overall structural stability.

[0128] The crossbeam 133, installed between the two first mounting beams 131, provides additional support and load-bearing capacity, enabling the mounting frame 130 to withstand greater loads and making it suitable for heavy-duty lifting tasks. This multi-beam combination design is modular, facilitating transportation, assembly, and disassembly, and improving the flexibility and applicability of the equipment.

[0129] In addition, by combining mounting beams of different lengths, the mounting frame 130 can better adapt to different operating environments and spatial layouts, optimizing the space occupied by the equipment.

[0130] In some embodiments, the two front and rear second mounting beams 132 and the two left and right first mounting beams 131 are welded together to form the main load-bearing mounting frame 130 of the entire lifting device.

[0131] In some embodiments, both the first mounting beam 131 and the second mounting beam 132 are made of channel steel, and the crossbeam 133 is made of square tubing.

[0132] In some embodiments, the left and right ends of the crossbeam 133 are sealed with plugs to serve both aesthetic and safety purposes.

[0133] In some alternative embodiments, the mounting bracket 130 may also include a plurality of reinforcing plates 134 disposed between adjacent first mounting beams 131 and second mounting beams 132.

[0134] It should be noted that the reinforcing plate 134 is located between the adjacent first mounting beam 131 and second mounting beam 132, providing additional support and reinforcement, which significantly improves the overall structural strength and durability of the mounting frame 130.

[0135] In addition, the presence of the reinforcing plate 134 reduces the relative movement and deformation between the first mounting beam 131 and the second mounting beam 132, ensuring the stability of the mounting frame 130 during hoisting and reducing the risk of vibration and swaying.

[0136] In some embodiments, the number of reinforcing plates 134 is eight to improve the structural strength of the entire mounting frame 130. The upper and lower reinforcing plates 134 at the corners of the mounting frame 130 are welded to the mounting frame 130, which helps to improve the stress stability of the structure and provides a welding surface for the first hook 140 and the second hook 150.

[0137] Specifically, the first hook 140 is welded to the second mounting beam 132, and the corresponding position is above the lifting of the first lifting device 110. This can fix the first hook 113, so that the inactive second hook 123 will not affect or bump the surface of the workpiece and normal operation.

[0138] The lifting fixture provided in this application embodiment is used to lift CTP battery packs. The CTP battery pack includes a frame and at least two layers of liquid cooling plates. The lifting fixture includes: a mounting frame having a first mounting position and a second mounting position; a lifting assembly disposed on the mounting frame, the lifting assembly including a first lifting tool and a second lifting tool, the first lifting tool being disposed at the first mounting position and used to lift the liquid cooling plates and stack the liquid cooling plates onto the frame; and the second lifting tool being disposed at the second mounting position and used to lift the frame to move the CTP battery pack.

[0139] By setting up lifting fixtures and integrating the first and second lifting fixtures on the same mounting frame, the space occupied is reduced, which can better meet the assembly and movement of CTP battery packs. This reduces the number of operation steps and time for operators. After the CTP battery packs are sealed, they also need to be transported and stored internally. This allows operators to quickly switch the function of the lifting fixtures without changing equipment or readjusting the installation position, thereby improving on-site operation efficiency, reducing the risk of operational errors, and improving the overall safety of operation.
