Description

Technical Field

[0001] The utility model relates to the field of hoisting, in particular to a hoisting tool. Background Art

[0002] The production process of lithium-ion batteries is mainly divided into battery cells (cells) and battery modules. The battery module production line requires the application of structural adhesive to the battery frame to enhance the battery's thermal conductivity and support. During this process, a lifting tool is required to transport the battery frame onto the production line. However, existing lifting tools mainly use electric hoists and slings for lifting. This leads to problems such as slow assembly and disassembly, low work efficiency, and complex operation. Therefore, providing an efficient and easy-to-use lifting tool has become the research direction of this utility model. Utility Model Content

[0003] The utility model aims to provide a lifting tool. The magnetic connection design adopted between the U-shaped buckle and the pin shaft not only significantly improves the stability and reliability of the connection between the two, but also greatly accelerates the efficiency of the disassembly operation and realizes the convenience of operation.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The utility model discloses a lifting tool, comprising a U-shaped buckle, wherein the two extending ends of the U-shaped buckle are respectively provided with corresponding through holes and countersunk holes; and further comprising a pin shaft, wherein the pin shaft passes through the through hole and is magnetically connected to a magnetic attraction block at the bottom of the countersunk hole.

[0006] A further solution includes a hanging ear connected to the U-shaped buckle.

[0007] A further solution: the U-shaped buckle and the hanging ear are hinged.

[0008] A further solution: the inner wall of the U-shaped buckle is provided with a first pad parallel to the pin shaft.

[0009] A further solution: the first spacer is made of bakelite.

[0010] A further solution: second pads are provided on the inner walls of the two extended ends of the U-shaped buckle.

[0011] A further solution: the second spacer is made of bakelite.

[0012] A further solution: a rope threading hole is provided at the top end of the pin shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This utility model uses a magnetic connection design between the U-shaped buckle and the pin, which not only improves the flexibility and fault tolerance during the installation process, but also greatly facilitates the inspection steps, allowing users to easily confirm whether the connection has reached a secure clamping state, and significantly enhances the safety of the hoisting process. During the hoisting process, this hoisting tool can ensure uniform force distribution, so that the hoisting level remains highly consistent; in addition, the tool itself is light and flexible, easy to operate, and can quickly complete the disassembly operation, further promoting the improvement of work efficiency. It is worth mentioning that by adding a bakelite pad inside the buckle body of the magnetic U-shaped buckle, the battery frame is effectively prevented from being accidentally scratched by the tool, further ensuring the safety and integrity of the battery module.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, a specific structure and operation, and therefore cannot be understood as a limitation on the present invention.

[0022] See also Figure 1-2In this embodiment, a lifting tool includes a U-shaped buckle 1, and the two extending ends of the U-shaped buckle 1 are respectively provided with corresponding through holes 11 and countersunk holes 12; and a pin 2. The opening of the U-shaped buckle 1 is used to place the object to be lifted (battery module outer frame 7), and the two extending ends of the U-shaped buckle 1 are parallel to each other and clamped on the upper and lower end faces of the battery module outer frame 7. The pin 2 passes through the through hole 11 and the mounting hole of the battery module outer frame 7 in sequence, and is magnetically connected to the magnetic block 3 built into the countersunk hole 12. The pin 2 is connected to the U-shaped buckle 1 by magnetic attraction, which not only improves the flexibility and fault tolerance during the installation process, but also greatly facilitates the inspection steps, allowing users to easily confirm whether the connection has reached a secure clamping state.

[0023] Furthermore, the lifting tool further comprises a lifting lug 4 connected to the U-shaped buckle 1, and the U-shaped buckle 1 is hinged to the lifting lug 4. During lifting, the lifting lug 4 can flexibly adjust its angle according to the pulling direction of the lifting rope 8.

[0024] Furthermore, the inner wall of the U-shaped buckle 1 is provided with a first spacer 5, parallel to the pin 2, and made of Bakelite. Second spacers 6, also made of Bakelite, are provided on the inner walls of the two extended ends of the U-shaped buckle 1. Bakelite has a moderate hardness and provides a good cushioning effect when in contact with the battery module outer frame 7, preventing scratches on the outer frame. Both the first spacer 5 and the second spacer 6 are screwed to the U-shaped buckle 1. Bakelite blocks of appropriate thickness can be selected based on the size of the battery module outer frame 7, providing high adaptability.

[0025] Furthermore, a rope hole 21 is provided at the top of the pin 2 to facilitate fastening the pin 2 to an anti-lost chain (not shown), thereby effectively preventing the pin 2 from accidentally falling off or being lost during use, thereby ensuring the safety and stability of the entire lifting tooling. The other end of the anti-lost rope is connected to the U-shaped buckle 1.

[0026] Please continue reading Figure 3-4 When using the present invention, first clamp the U-shaped buckle 1 onto the battery module outer frame 7, aligning the through hole 11 with the mounting hole of the battery module outer frame 7. Then insert the pin 2. After ensuring that the bottom of the pin 2 is firmly connected to the magnetic block 3, the installation of a single lifting fixture is complete. Next, follow the same steps to install four lifting fixtures on the battery module outer frame 7 in sequence, then connect the lifting rope 8 to the lifting lug 4 together, and then gather the other ends of all the lifting ropes and connect them together to the hook of the lifting device, and then lift.
