Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0029] like Figures 1 to 4 As shown, in this embodiment, the oil drum handling device includes: a base frame 10, a lifting structure 20 and a clamping structure 30. A plurality of walking wheels 11 are arranged at the bottom of the base frame 10. The lifting structure 20 is movably arranged on the base frame 10. The clamping structure 30 is arranged on the lifting structure 20, and the clamping structure 30 includes a plurality of clamping claws 31 and a first transmission structure 32. The first transmission structure 32 is driven and cooperated with the plurality of clamping claws 31, and the plurality of clamping claws 31 have a clamping state and an open state. Among them, when the lifting structure 20 moves up, it drives the first transmission structure 32 to move up, and when the first transmission structure 32 moves up, it can drive the plurality of clamping claws 31 to switch from the open state to the clamping state.

[0030] According to the technical solution of this embodiment, a plurality of running wheels 11 are arranged at the bottom of the base frame 10, a lifting structure 20 is arranged on the base frame 10, a clamping structure 30 is arranged on the lifting structure 20, and the clamping structure 30 includes a plurality of clamping claws 31 and a first transmission structure 32. When the lifting structure 20 moves upward, it can drive the first transmission structure 32 to move upward, and when the first transmission structure 32 moves upward, it can drive the clamping claws 31 to switch from an open state to a clamping state. Through the above arrangement, when carrying an oil barrel, the oil barrel carrying device is moved to the oil barrel, the lifting structure 20 is moved downward, so that the clamping structure 30 is clamped on the oil barrel, and then the lifting structure 20 is driven to move upward. When the lifting structure 20 moves upward, the plurality of clamping claws 31 are driven to switch from an open state to a clamping state through the first transmission structure 32, thereby clamping the oil barrel and lifting the oil barrel. At this time, there is a certain distance between the bottom surface of the oil barrel and the ground, and the oil barrel carrying device can be pushed under the action of the running wheel 11, thereby carrying the oil barrel. This not only makes the operation simpler, but also has a higher efficiency in carrying. Therefore, the technical solution of this embodiment effectively solves the problem of low efficiency of manual handling of oil drums in the related art.

[0031] Specifically, through this design, the oil barrel handling device can automatically adapt to oil barrels of different heights, improve handling efficiency, and is particularly suitable for scenes where oil barrels need to be frequently handled, such as warehouses and factories. This automatic height adjustment function can significantly reduce the physical labor of operators. At the same time, due to the adjustment of the clamping structure 30, the stability of the oil barrel during the handling process is significantly improved, effectively preventing the oil barrel from tipping over or sliding during the handling process, greatly reducing the safety hazards during the handling process, especially in a small space with oil barrels of different heights, the superiority of this design is more obvious.

[0032] like Figure 4 , Figure 6 as well as Figure 7 As shown, in this embodiment, the clamping structure 30 also includes a mounting frame 33, and the first transmission structure 32 is movably arranged in the mounting frame 33, and each clamping jaw 31 is hingedly connected to the mounting frame 33 and cooperates with the first transmission structure 32 in transmission. This structure enables the clamping jaw 31 to flexibly clamp and open under the drive of the first transmission structure 32, ensuring the stability and safety of the oil barrel during the transportation process, and is suitable for transportation environments where the shapes and sizes of the oil barrels are slightly different. When the size or shape of the oil barrel changes slightly, the clamping jaw 31 can automatically adapt to the shape of the oil barrel according to the adjustment of the first transmission structure 32. Through this design, the oil barrel handling device can seamlessly connect various oil barrels, improve the versatility and efficiency of handling, and reduce the frequency of replacing the handling equipment due to changes in the size of the oil barrel.

[0033] like Figure 4 , Figure 6 as well as Figure 7As shown, in this embodiment, the first transmission structure 32 includes a plurality of gears 321 and a transmission block 322, a plurality of tooth grooves 3221 are arranged on the side wall of the transmission block 322, a plurality of gears 321 are arranged corresponding to a plurality of clamping jaws 31, each gear 321 is fixedly arranged at the end of the corresponding clamping jaw 31, the gear 321 is rotatably arranged on the mounting frame 33, and the tooth grooves 3221 are arranged in meshing with the gears 321. The coordinated use of the gears 321 and the tooth grooves 3221 not only improves the transmission efficiency, but also ensures the accuracy and reliability of the action of the clamping jaw 31, and is suitable for the handling of oil drums on industrial production lines that require high-precision operations.

[0034] In practical applications, this precise transmission design can ensure that the oil drums are accurately clamped and placed, avoiding the position deviation of the oil drums caused by transmission errors, and improving the automation level and efficiency of the production line.

[0035] like Figure 4 , Figure 6 as well as Figure 7 As shown, in this embodiment, the mounting frame 33 includes a bottom plate portion 331, a top plate portion 332 and a plurality of connecting blocks 333, wherein the plurality of connecting blocks 333 are arranged at intervals between the bottom plate portion 331 and the top plate portion 332, and each gear 321 is rotatably connected between two adjacent connecting blocks 333. This structural design makes the entire clamping structure 30 more stable, capable of withstanding the impact and vibration during the transportation of the oil drum, and is suitable for scenes with complex road conditions and bumpy transportation.

[0036] In complex handling environments, this stable design can effectively resist various unstable factors during the handling process, such as uneven ground, excessive handling speed, etc., ensuring that the oil drums will not be displaced or damaged due to external forces during the handling process, thereby improving the safety of handling and the integrity rate of the oil drums.

[0037] like Figure 4 , Figure 6 as well as Figure 7 As shown, in this embodiment, there is a distance a between the bottom plate portion 331 and the top plate portion 332, and the height of the transmission block 322 is a distance b, wherein the distance a and the distance b satisfy: 1.2≤a / b≤1.6. By precisely controlling the proportional relationship between the transmission block 322 and the mounting frame 33, the motion trajectory of the clamp 31 can be optimized to ensure efficient and stable clamping of the oil drum in a limited space, which is suitable for internal handling in warehouses with limited space. This design can ensure that the motion trajectory of the clamp 31 is more optimized, and the oil drum can be clamped and carried quickly and accurately even in narrow passages, reducing the risk of collision during handling, and is suitable for internal handling of oil drums in various types of warehouses.

[0038] Specifically, in this embodiment, the ratio between the distance a and the distance b is 1.3.

[0039] It should be noted that, at the beginning, the transmission block 322 can be abutted against the bottom plate portion 331 under the action of gravity. At this time, the clamping claw 31 is in an open state under the action of the gear 321 and the tooth groove 3221. When the lifting member 22 is raised, the lifting frame 21 can pull the transmission block 322 to separate the transmission block 322 from the bottom plate portion 331, and when the transmission block 322 is raised, the gear 321 cooperates with the tooth groove 3221, thereby causing the clamping claw 31 to swing and be in a clamping state. At this time, as the lifting frame 21 moves upward, the clamping force of the clamping claw 31 gradually increases, thereby preventing the clamping claw 31 from being separated from the oil drum.

[0040] like Figure 4 , Figure 6 as well as Figure 7 As shown, in this embodiment, a relief notch 3321 is provided on the top plate 332, and the clamping structure 30 further includes a connecting ring 34, which passes through the relief notch 3321 and is connected to the transmission block 322. The design of the relief notch 3321 and the connecting ring 34 ensures that the clamping structure 30 will not be hindered during the lifting process, and can smoothly clamp and release the oil drum, which is suitable for logistics centers that need to frequently carry oil drums up and down.

[0041] In logistics centers, the handling height and frequency of oil drums are often high. The design of the avoidance gap 3321 and the connecting ring 34 ensures barrier-free lifting of the clamping structure 30, improves the continuity and efficiency of the handling process, and reduces handling interruptions caused by lifting obstacles.

[0042] like Figures 1 to 5 As shown, in this embodiment, the base frame 10 includes a bottom frame 12 and a vertical frame 13 connected to the bottom frame 12, and the lifting structure 20 is arranged on the vertical frame 13. The combined design of the bottom frame 12 and the vertical frame 13 not only provides sufficient supporting force, but also ensures the mobility of the entire device, which is suitable for the scene where the oil drum needs to be moved and transported between different working areas.

[0043] Specifically, in the complex environment of a factory or warehouse, this design can ensure that the oil drum handling device maintains good mobility while carrying heavy objects, and can flexibly move around even in narrow aisles or complex layouts, thereby improving the flexibility and efficiency of handling and reducing handling time. It is suitable for large factories or warehouses that need to frequently transport oil drums between multiple work areas, ensuring the continuity and efficiency of the production or logistics process.

[0044] like Figures 1 to 5As shown, in this embodiment, the lifting structure 20 includes a lifting frame 21, a lifting member 22 and a second transmission structure 23. The second transmission structure 23 is connected between the lifting frame 21 and the base frame 10. The lifting member 22 drives and cooperates with the second transmission structure 23. The lifting member 22 can push the second transmission structure 23 to move up and down to drive the lifting frame 21 to move up and down. This design makes the movement of the lifting structure 20 more stable, can accurately control the lifting height of the oil drum, and is suitable for an automated production line that needs to accurately control the position of the oil drum.

[0045] Specifically, on automated production lines, the lifting height and position of oil drums often need to be very precise. This design can ensure that the oil drums are accurately placed in designated positions, thereby improving the automation level and production efficiency of the production line and reducing production line downtime caused by oil drum position errors. It is suitable for various automated production lines that require high-precision operations, such as automobile manufacturing, chemical production, etc., ensuring efficient and stable operation of the production line.

[0046] like Figures 1 to 5 As shown, in this embodiment, the second transmission structure 23 includes a transmission chain 231 and a sprocket 232. The first end of the transmission chain 231 is connected to the base frame 10, the second end of the transmission chain 231 is connected to the lifting frame 21, and the sprocket 232 is rotatably arranged on the lifting member 22. The sprocket 232 drives and cooperates with the transmission chain 231. When the lifting member 22 is raised, the sprocket 232 can rise and drive the transmission chain 231 to reduce the distance between the first end of the transmission chain 231 and the second end of the transmission chain 231. The coordinated use of the transmission chain 231 and the sprocket 232 not only improves the stability and efficiency of the transmission, but also can adapt to various loads, and is suitable for scenes where oil drums of different weights need to be carried.

[0047] In practical applications, this design can ensure that the oil drum handling device maintains stable performance when handling oil drums of different weights, reducing transmission failures caused by load changes. It is suitable for various industrial scenarios that require handling oil drums from light to heavy, such as chemical raw material warehouses, refineries, etc., ensuring the efficiency and stability of the handling process, reducing maintenance costs, and increasing the service life of the equipment.

[0048] like Figures 1 to 5As shown, in this embodiment, the oil drum handling device also includes a guide structure 40, and the guide structure 40 includes a guide groove 41 and a guide wheel 42, one of the guide groove 41 and the guide wheel 42 is arranged on the lifting frame 21, and the other of the guide groove 41 and the guide wheel 42 is arranged on the stand 13. The addition of the guide structure 40 ensures the linearity and stability of the lifting frame 21 during the up and down movement, prevents the deviation during the handling process, and is suitable for scenes requiring long-distance linear handling of oil drums. When the oil drums are transported in a long-distance linear manner, the guide structure can ensure the vertical movement of the lifting frame, prevent the handling deviation caused by the lateral force, improve the handling accuracy, and reduce the energy loss during the handling process. It is suitable for scenes requiring long-distance and high-precision handling of oil drums.

[0049] The oil drum handling device of this embodiment drives the clamping structure 30 to move up and down through the lifting structure 20, and uses the first transmission structure 32 to realize the automatic switching of the clamping and opening states of the clamping claw 31, which greatly improves the efficiency and safety of handling the oil drum. In practical applications, this device can significantly reduce manual operations, reduce potential risks in the handling process, and improve the level of automation in the handling process. It is suitable for oil drum handling operations in various industrial environments and has broad application prospects and significant economic benefits. In addition, the device also has the characteristics of modular design, and can be customized according to different working environments and needs, such as adding remote control functions, etc., which further broadens its scope of application and meets the needs of modern industry for efficient, safe, and intelligent handling equipment.

[0052] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
