Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting device. Background Technology

[0002] During the stacking and transfer of PACK battery modules in production, lifting fixtures are required. Since the battery modules are not protected, they are prone to collisions. The transfer process requires 2 to 3 people to complete, resulting in significant labor costs. Generally, one type of lifting fixture can only be used for one size of battery module, lacking versatility. Furthermore, different models of traditional lifting tools are needed to match the different module models on site. As the number of module models increases, the number of lifting tools also increases, further increasing production and management costs. Simultaneously, traditional lifting tools on site apply force to the upper part of the module, leaving the lower part vulnerable to safety hazards. Traditional lifting tools are no longer sufficient to meet the demands of the ever-increasing number of battery module models.

[0003] Chinese patent (authorization announcement number CN 211813043 U, authorization announcement date 2020.10.30) discloses a battery module hoisting device. Its technical solution involves setting up a hoisting component and a stop component that slide through a guide rod, allowing the distance between the two hoisting components to be adjustable to accommodate battery modules of different sizes. The battery module is then fixed by fixing holes in the hoisting structure combined with fixing rods that fasten to both ends. Clearly, this hoisting method, which uses fixing rods to fasten the upper ends of the battery module, suffers from insecure fixation and poses a safety hazard due to stress on the lower part of the battery module.

[0004] Therefore, how to provide a hoisting device that is compatible with multiple battery module models, reduces the labor and management costs of battery module hoisting, and improves production efficiency and safety is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention proposes a hoisting device, which aims to solve the technical problems of poor battery module fixation and low safety in the above-mentioned traditional battery module hoisting devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a hoisting device, including:

[0008] Hanger,

[0009] The pallet includes a base plate and a side plate assembly arranged perpendicular to the base plate; the lower end of the side plate assembly is fixed to one side of the base plate to form an L-shaped pallet structure; the upper end of the side plate assembly is hinged to the lower end of the hanger.

[0010] A pull strap, one end of which is connected to the upper part of the hanger and the other end of which is connected to the side end of the base plate away from the side plate assembly, to taut the base plate in the lifting state and make the top surface of the base plate horizontal or tilted to one side of the side plate assembly.

[0011] The lifting device of this utility model has a lifting frame connected to a hoisting device; the pallet serves as the main tooling, with its bottom plate's top surface being the placement surface for the battery modules. The L-shaped pallet structure is compatible with all battery module models within its size range. During hoisting, the battery modules are manually moved from the stacking station to the top surface of the bottom plate, with the sidewalls of the battery modules pressed against the inner wall of the side panel assembly. The lifting frame is then raised by the hoisting device, thereby lifting the pallet to transfer the battery modules to the unloading area. The tension straps, when stretched, stabilize the side of the bottom plate, ensuring the top surface of the bottom plate is horizontal or tilted towards the side panel assembly. This allows the battery modules to remain close to the inner wall of the side panel assembly during transport, preventing them from swaying or shifting. The tension straps also provide protection, preventing the battery modules from falling off the pallet. This utility model lifting device is easy to operate. The operation mode has been changed from the traditional two-person operation of carrying and installing battery modules, and one person responsible for transfer, to one person carrying and installing the module and transferring it at the same time, or two people carrying, installing, and transferring the module. This can reduce the labor intensity of workers, improve work efficiency, and reduce production costs. Moreover, it can complete the transfer of battery modules of various specifications and sizes, and has strong applicability. The pallet support force acts on the bottom of the battery module, which shifts the overall stress point of the battery module downward, increases safety, improves the safety factor of handling, and can ensure battery quality.

[0012] As a further improvement to the above technical solution, the hanger includes a top plate, a first vertical plate, a second vertical plate, and a lifting lug assembly; the lifting lug assembly is installed on the top plate surface; the upper ends of the first vertical plate and the second vertical plate are vertically fixed to opposite ends of the top plate; the side plate assembly is arranged along the opposite direction of the first vertical plate and the second vertical plate, and the upper ends of both sides of the side plate assembly in the length direction are hinged to the lower ends of the first vertical plate and the second vertical plate; one end of the pull strap is connected to the top plate.

[0013] The beneficial effects of the above technical solution are: the lifting lug assembly is used to connect the lifting device; the top plate serves as the main load-bearing plate for lifting, connecting one end of the pallet through upright plate one and upright plate two, and connecting the other end of the pallet through the pull strap, thereby improving the stability of lifting.

[0014] As a further improvement to the above technical solution, the lifting lug assembly includes multiple lifting lugs; the top plate includes a strip-shaped main lifting plate and a strip-shaped auxiliary lifting plate; one end of the strip-shaped auxiliary lifting plate is vertically fixed to the middle of the strip-shaped main lifting plate in the length direction to form a T-shaped top plate structure; the lifting lugs are installed on the upper surface of both the strip-shaped main lifting plate and the strip-shaped auxiliary lifting plate.

[0015] The upper ends of the first upright plate and the second upright plate are vertically fixed at both ends of the main strip hanging plate along its length; one end of the pull strap is detachably connected to the auxiliary strip hanging plate.

[0016] The beneficial effects of the above technical solution are as follows: the strip-shaped main hanging plate is used to bear the tension of the first and second vertical plates; the strip-shaped auxiliary hanging plate is used to bear the tension of the pull strap; lifting lugs are installed on the upper surface of both the strip-shaped main hanging plate and the strip-shaped auxiliary hanging plate, which can improve the uniformity of the lifting force. Removing one end of the pull strap facilitates the installation of the battery module, and the pull strap is reconnected after the battery module is installed in place, making the operation convenient.

[0017] As a further improvement to the above technical solution, the hanger also includes stiffening plates; the stiffening plates are arranged along the opposite direction of the first vertical plate and the second vertical plate and are located below the strip-shaped main hanger plate, and the two ends of the stiffening plates in the length direction are fixed to the upper parts of the first vertical plate and the second vertical plate respectively.

[0018] The beneficial effects of the above technical solution are: the stiffening plates can strengthen the structural rigidity of vertical plate one and vertical plate two, and further improve the stability of the hanger.

[0019] As a further improvement to the above technical solution, the side panel assembly includes side panel one, side panel two, and side panel three; side panel one is arranged along the opposite direction of upright panel one and upright panel two, and the surfaces of side panel two and side panel three are horizontally opposite each other and vertically fixed at both ends of the length direction of side panel one to jointly form a U-shaped enclosure structure; the lower ends of side panel one, side panel two, and side panel three are fixed to one side of the base plate; the upper ends of side panel two and side panel three are hinged to the lower ends of upright panel one and upright panel two respectively.

At this time, one end of the battery module is embedded in the U-shaped enclosure structure. The second and third side plates can act as a barrier to prevent the battery module from sliding off the base plate.

[0021] As a further improvement to the above technical solution, the other end of the pull strap is detachably connected to the side of the base plate away from the side plate assembly.

[0022] The beneficial effect of the above technical solution is that the other end of the pull strap can be detachably connected to the side end of the base plate, which makes it convenient for workers to move and place the battery module.

[0036] According to the embodiments of this utility model, such as Figures 1 to 2 As shown, a hoisting device includes:

[0037] Hanger 1,

[0038] Pallet 2 includes a base plate 21 and a side plate assembly 22 arranged vertically to the base plate 21; the lower end of the side plate assembly 22 is fixed to one side of the base plate 21 to form an L-shaped pallet structure; the upper end of the side plate assembly 22 is hinged to the lower end of the hanger 1.

[0039] The pull strap 3 is connected at one end to the upper part of the hanger 1 and at the other end to the side of the base plate 21 away from the side plate assembly 22, so as to straighten the base plate 21 in the lifting state and make the top surface of the base plate 21 horizontal or tilted to one side of the side plate assembly 22.

[0040] In this embodiment, the lifting device has a lifting frame 1 connected to a hoisting device. The pallet 2 serves as the main tooling, with its base plate 21 having a top surface for placing the battery module 5. The L-shaped pallet structure is compatible with all battery module models within the specified size. During hoisting, the battery module 5 is manually moved from the stacking station to the top surface of the base plate 21, with the sidewall of the battery module 5 resting against the inner wall of the side plate assembly 22. The lifting device then lifts the lifting frame 1 upwards, thereby lifting the pallet 2 to transfer the battery module 5 to the unloading area. The tension strap 3, when stretched, stabilizes the side of the base plate 21, ensuring the top surface of the base plate 21 is horizontal or tilted towards the side plate assembly 22. This prevents the sidewall of the battery module 5 from swaying or shifting during transport, as it rests against the inner wall of the side plate assembly 22. The tension strap 3 also provides protection, preventing the battery module 5 from falling off the pallet 2. This utility model lifting device is easy to operate. The operation mode has been changed from the traditional two-person operation of carrying and installing the battery module 5, and one person responsible for transfer, to one person carrying and installing the module and transferring it at the same time, or two people carrying, installing, and transferring the module. This can reduce the labor intensity of workers, improve work efficiency, and reduce production costs. Moreover, it can complete the transfer of battery modules 5 of various specifications and sizes, and has strong applicability. The supporting force of the tray 2 acts on the bottom of the battery module 5, so that the overall stress point of the battery module 5 is lowered, which increases safety and improves the safety factor of handling, thus ensuring battery quality.
