For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Example, refer to Figures 1-2 As an embodiment of this utility model, a lifting device for ton-bag cargo in forklift operation is proposed. It is used to be installed on the forklift boom 13 of the forklift and includes a positioning seat 1, a lifting arm 2, and a hanger 3. The positioning seat 1 is used to be installed on the forklift boom 13; the lifting arm 2 is set on the positioning seat 1 and located below the positioning seat 1. There are multiple lifting arms 2, and all the lifting arms 2 are arranged in the left and right direction; the hanger 3 is set on the lifting arm 2 and is used to hang ton-bag cargo.

[0035] In this embodiment, the positioning base 1 serves as a connector and load-bearing element, providing an installation foundation for the lifting arms 2 and the hangers 3. Multiple lifting arms 2 are arranged horizontally on the positioning base 1, allowing for the simultaneous lifting of multiple ton bags. This arrangement provides a more even distribution of force, making the entire lifting device more stable during lifting. The hangers 3 can be designed according to the characteristics of the ton bags; for example, they can be hooks, ropes, or other structures adapted to the ton bags. As long as they can firmly hold the ton bags, the position of the ton bags will remain relatively stable during lifting, reducing the risk of cargo slippage.

[0036] When it is necessary to lift ton-bag type goods, the bucket of the forklift is removed from the forklift boom 13, the positioning seat 1 is installed on the forklift boom 13, the operator drives the forklift to a suitable position, and by operating the forklift boom 13, the positioning seat 1, the lifting arm 2 and the hanger 3 are in the right position. Then the ton-bag is hung on the hanger 3, and the ton-bag can be lifted by operating the forklift boom 13 to move the ton-bag from one position to another. Then the ton-bag is separated from the hanger 3. The loading and unloading of multiple ton-bags can be completed at one time.

[0037] This invention, by using the hook 3 to hold the ton bag, avoids the problem of the bucket being unable to accommodate the goods or the goods slipping during scooping. It also reduces direct physical impact on the ton bag, lowers the possibility of damage, and better protects the integrity of the goods. Moreover, the connection and disassembly between the ton bag and the hook 3 are simple and convenient, which can improve production efficiency. This enables efficient, safe, and stable handling and loading / unloading of ton bag goods, better meeting usage requirements.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, each lifting arm 2 has multiple hangers 3, all of which are arranged vertically. When the height of the positioning base 1 remains constant, the multiple hangers 3 arranged vertically on each lifting arm 2 can adapt to the handling and loading / unloading needs of ton-sized goods of different heights, thus expanding the applicability of this lifting tool.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the lower end of the positioning seat 1 has a connecting sleeve 4, and the lifting arm 2 is threadedly connected to the connecting sleeve 4. The connecting sleeve 4 at the lower end of the positioning seat 1 provides the installation position and positioning reference for the lifting arm 2. The threaded connection allows the lifting arm 2 to be screwed into or out of the connecting sleeve 4 by rotation. The self-locking characteristic of the thread ensures the firmness and reliability of the connection, guaranteeing that it will not easily loosen or detach during the lifting process, even under large loads and vibrations, thus ensuring operational safety. Through the thread profile engagement, a large frictional force and axial tensile force are generated when tightening, stably fixing the lifting arm 2 to the positioning seat 1. This connection method allows the length of the lifting arm 2 extending out of the positioning seat 1 to be adjusted according to actual usage needs, thereby changing the working position and range of the lifting arm 2. This facilitates the adjustment of lifting parameters, improves the adjustability and versatility of the equipment, and reduces the possibility of needing to replace the equipment due to changes in the work environment.

[0040] Furthermore, the positioning seat 1 and the connecting sleeve 4 are integrally formed. Manufacturing the positioning seat 1 and the connecting sleeve 4 as a whole eliminates the connection interface between them, ensuring the structural strength and integrity of the components. In this way, when bearing the lifting load, the force will be continuously transmitted within the overall structure, making the structure more evenly stressed. This avoids stress concentration and potential weak points caused by the presence of connection parts, which can extend the service life of the equipment, reduce maintenance costs and downtime caused by connection component failures, improve the reliability and stability of the equipment, and enable it to maintain stable performance during long-term high-intensity lifting operations.

[0041] Furthermore, such as Figure 1 and Figure 2As shown, it also includes a positioning component 5 and a load-bearing nut 6. One end of the positioning component 5 is fitted around the outside of the lifting arm 2, and the hanger 3 is set at the other end of the positioning component 5. The load-bearing nut 6 is threadedly connected to the lifting arm 2, and the positioning component 5 overlaps with the load-bearing nut 6. The load-bearing nut 6 threadedly connected to the lifting arm 2 provides a platform for connection and load-bearing for the positioning component 5. The positioning component 5, fitted onto the lifting arm 2, provides a platform for connection and load-bearing for the hanger 3. The weight of the ton bag borne by the hanger 3 is transferred to the lifting arm 2 through the positioning component 5. By changing the vertical position of the load-bearing nut 6 on the lifting arm 2, the vertical positions of the positioning component 5 and the hanger 3 can be changed, better adapting to the handling and loading / unloading needs of ton bags of different heights. The structure is simple, the adjustment is convenient and quick, and it saves time and effort.

[0042] Furthermore, such as Figure 1 and Figure 2 As shown, it also includes a clamping nut 7, which is threadedly connected to the lifting arm 2; the positioning element 5 is clamped between the clamping nut 7 and the bearing nut 6. The clamping nut 7 and the bearing nut 6 work together to apply clamping force to the positioning element 5, firmly fixing the positioning element 5 to the lifting arm 2 from both above and below. This prevents the positioning element 5 from moving axially, further enhances the fixing effect of the positioning element 5, improves the accuracy and stability of the hanging part 3 position, reduces safety hazards caused by the loosening of the positioning element 5, and ensures the safety and stability of the ton bag during the lifting process.

[0043] Furthermore, such as Figure 3 As shown, it also includes a wear-resistant sleeve 8, which is fitted around the periphery of the lifting arm 2 and located inside the positioning component 5. The wear-resistant sleeve 8 is made of wear-resistant material, and its hardness and wear resistance are superior to those of the material of the positioning component 5. When the positioning component 5 moves relative to the lifting arm 2 or bears a load, it can reduce the direct friction between the two and extend the service life of the positioning component 5.

[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the lower end of the lifting arm 2 has an anti-detachment protrusion 9, and the bearing nut 6 is located above the anti-detachment protrusion 9. The anti-detachment protrusion 9 is located at the lower end of the lifting arm 2 and serves as a limit. When the bearing nut 6 tends to loosen downwards due to various reasons (such as vibration, uneven force, etc.), the anti-detachment protrusion 9 will prevent the bearing nut 6 from moving further downwards, preventing the bearing nut 6 from falling off the lifting arm 2, thereby avoiding loosening or failure of the hanger 3. This can improve the reliability and safety of the equipment, reduce the maintenance frequency of the equipment, and reduce downtime caused by failure.

[0045] Furthermore, such as Figure 1 and Figure 2As shown, it also includes a connector 10. The lower end of the connector 10 is connected to the positioning seat 1, and the upper end of the connector 10 has a connecting hole 11 for connecting to the loader boom 13. There are multiple connectors 10, and all connectors 10 are arranged in a left-right direction. The lower end of the connector 10 is connected to the positioning seat 1, and the connecting hole 11 at the upper end of the connector 10 can be connected to the loader boom 13 through bolts, nuts, pins, or other connectors, thereby stably installing the positioning seat 1 on the loader boom 13 and realizing the transmission of force. The arrangement of multiple connectors 10 distributes the force of the loader boom 13 to the positioning seat 1, making the connection more secure and stable.

[0046] Furthermore, such as Figure 4 and Figure 5 As shown, the bottom surface of the positioning seat 1 has a dovetail groove 12, which is arranged along the front-to-back direction. The connecting member 10 includes a horizontal plate 10-1 and a vertical plate 10-2. The horizontal plate 10-1 is located at the bottom of the positioning seat 1 and is inserted into the dovetail groove 12. The lower end of the vertical plate 10-2 is connected to the horizontal plate 10-1, and the connecting hole 11 is located on the vertical plate 10-2. The rear end face of the positioning seat 1 contacts the front side face of the vertical plate 10-2. The horizontal plate 10-1 and the positioning seat 1, and the vertical plate 10-2 and the positioning seat 1 can be locked together by bolts and nuts, or they can be welded together. There are at least three dovetail grooves 12, and all the dovetail grooves 12 are arranged along the left-to-right direction. The shape of the upper end of the horizontal plate 10-1 matches the shape of the dovetail groove 12. The insertion of the horizontal plate 10-1 into the dovetail groove 12 increases the connection area between the horizontal plate 10-1 and the positioning seat 1, making the connection between the two more secure and reliable.
