[0026] Embodiment one:

[0027] As shown in Figs. 1-3 The present application provides a kind of for molten metal liquid's transfer bucket access device, comprising: transfer bucket 10, storage support and lifting assembly 20, transfer bucket 10 includes barrel part 11 and conical part 12, conical part 12 is set to the lower of barrel part 11, storage support is provided with the accommodating groove of open towards top, accommodating groove is suitable for accommodating conical part 12, lifting assembly 20 is movably connected with storage support, lifting assembly 20 can be selectively moved in horizontal direction towards transfer bucket 10 and is cooperated with transfer bucket 10, and lifting assembly 20 can be selectively moved in height direction towards or away from storage support, to drive transfer bucket 10 to rise or fall.

[0028] In some embodiments, the transfer bucket 10 is composed of two parts, that is, the transfer bucket 10 comprises a barrel part 11 and a conical part 12, wherein the conical part 12 is located below the barrel part 11 to help reduce the residual molten metal during the transfer process, and also facilitate the stacking of the transfer bucket 10, the storage support is a fixed structure, and the storage support is designed with an accommodating groove open towards the top, the shape and size of the accommodating groove match the conical part 12 of the transfer bucket 10, so that the transfer bucket 10 can be stably placed on the support, the lifting assembly 20 is connected with the storage support, and the lifting assembly 20 can move in the horizontal direction to approach or move away from the transfer bucket 10, in addition, the lifting assembly 20 can also move in the vertical direction to realize the lifting or lowering of the transfer bucket 10, thereby the lifting assembly 20 can be closely matched with the transfer bucket 10 to complete the access operation of the transfer bucket 10.

[0029] It can be understood that when the transfer bucket 10 needs to be accessed, the lifting assembly 20 will first move in the horizontal direction to the transfer bucket 10 until the lifting assembly 20 is in contact with the transfer bucket 10 and forms a stable connection, once the lifting assembly 20 is connected with the transfer bucket 10, the lifting or lowering of the transfer bucket 10 can be realized by controlling the vertical movement of the lifting assembly 20, the lifting operation is used to take out the transfer bucket 10 from the storage support, and the lowering operation is used to put the transfer bucket 10 back on the storage support. It is worth noting that the matching and separation of the lifting assembly 20 and the transfer bucket 10 is realized by specific mechanical structures (such as hooks, buckles, etc.), which ensures the safety and reliability during operation.

[0030] According to the transfer bucket access device for molten metal liquid of the utility model, a plurality of transfer buckets 10 can be stacked in the height direction, which reduces the area occupied by the storage of the transfer bucket 10, and more transfer buckets 10 can be stacked at the same height, which reduces the volume occupied by the storage of the transfer bucket 10, and through the specially designed lifting assembly 20 and the storage support, a plurality of transfer buckets 10 can be conveniently stacked and stored in the height direction, and the lifting assembly 20 can drive the transfer bucket 10 to move, thereby facilitating the storage of the transfer bucket 10, that is, the mechanized access mode significantly improves the operation efficiency of the transfer bucket 10, reduces the labor cost, and speeds up the production process.

[0031] Embodiment two:

[0032] In this embodiment, on the basis of embodiment one, the inside of the barrel part 11 is formed with a first accommodating groove of a roller in the height direction, the conical part 12 is provided with a second accommodating groove open towards the barrel part 11, the first accommodating groove and the second accommodating groove are communicated, and the conical part 12 of an adjacent transfer bucket 10 is accommodated in the first accommodating groove and the second accommodating groove of an adjacent other transfer bucket 10, so as to stack the adjacent two transfer buckets 10 in the height direction.

[0033] It can be understood that the first receiving groove inside the barrel part 11 is designed to accommodate the conical part 12 of another transfer barrel 10, which makes the conical part 12 of the upper transfer barrel 10 inserted into the barrel part 11 of the lower transfer barrel 10 when stacked, increasing the stability of the stack, and the second receiving groove of the conical part 12 is in communication with the first receiving groove, further strengthening the connection between the upper and lower transfer barrels 10, so that the projection of the two adjacent transfer barrels 10 in the horizontal direction overlaps to a higher degree, so that more transfer barrels 10 can be stacked at the same height.

[0034] Therefore, through this stacking design, more transfer barrels 10 can be stored in a limited space, thereby improving the space utilization rate of the warehouse or production site, and the double design of the first receiving groove and the second receiving groove ensures the stability of the transfer barrel 10 when stacked, reducing the risk of tipping due to external vibration or other factors. Of course, the stacking design allows the transfer barrels 10 to be arranged neatly, facilitating access operations, especially when using a mechanical arm or lifting assembly 20 for access, this design can significantly improve the convenience and efficiency of operation, at the same time, through the above setting, the mutual collision of the transfer barrels 10 during storage and handling can be reduced, and the risk of damage to the transfer barrels 10 is reduced.

[0035] In some embodiments, a stepped surface is formed between the conical part 12 and the barrel part 11, whereby when the two adjacent transfer barrels 10 are stacked on each other, the stepped surface of the upper transfer barrel 10 can abut against the top surface of the barrel part 11 of the lower transfer barrel 10, thereby making the two adjacent transfer barrels 10 stack more stably.

[0036] Embodiment three:

[0037] This embodiment is based on embodiment two, the outer peripheral wall of the barrel part 11 is provided with a fixing groove 111, and the lifting assembly 20 comprises a connecting plate 21 and a fixing rod 22, the connecting plate 21 is movably connected with the storage support, the connecting plate 21 has a first state and a second state, and the fixing rod 22 is connected with the connecting plate 21; wherein in the first state, the fixing rod 22 is accommodated in the fixing groove 111, and when the fixing rod 22 is accommodated in the fixing groove 111, the fixing rod 22 abuts against the inner wall of the fixing groove 111 in the height direction; in the second state, the fixing rod 22 is spaced from the fixing groove 111 in the horizontal direction.

[0038] In some embodiments, when the connecting plate 21 is in the first state, the fixed rod 22 is accommodated in the fixed groove 111 of the barrel part 11, at this time, the fixed rod 22 is in abutment with the inner wall of the fixed groove 111 in the height direction, that is, the fixed rod 22 cannot move up and down in the fixed groove 111 at this time, thereby ensuring the stability of the transfer barrel 10 during lifting or lowering; when the connecting plate 21 is in the second state, the fixed rod 22 is spaced apart from the fixed groove 111 in the horizontal direction, that is, the fixed rod 22 is disengaged from the fixed groove 111 at this time.

[0039] It can be understood that, in the first state, the fixed rod 22 is in abutment with the inner wall of the fixed groove 111, which ensures the stability of the transfer barrel 10 during lifting or lowering, reduces the safety risk caused by accidental movement, and in the second state, the fixed rod 22 is separated from the fixed groove 111, so that the access operation of the transfer barrel 10 can be safely performed, thereby avoiding the risk of jamming or damage of the fixed rod 22.

[0040] Through the state switching of the connecting plate 21, the accommodation and disengagement of the fixed rod 22 can be easily realized, and the access operation is simplified, that is, the operator only needs to control the state of the connecting plate 21 to complete the fixing and releasing of the transfer barrel 10, thereby improving the access work efficiency of the transfer barrel 10.

[0041] According to some embodiments of the present application, the lifting assembly 20 further comprises: a telescopic motor 23, the telescopic motor 23 is connected with the storage support, the telescopic motor 23 has a telescopic end that can be selectively moved towards or away from the accommodating groove, and the telescopic end is connected with the connecting plate 21.

[0042] It can be understood that the telescopic motor 23 is connected with the storage support, and the telescopic motor 23 can move the telescopic end towards or away from the accommodating groove when it is working, and since the telescopic end is connected with the connecting plate 21, the telescopic motor 23 can drive the connecting plate 21 to move towards or away from the transfer barrel 10 when it is working, thereby driving the fixed rod 22 to be accommodated in the fixed groove 111 or driving the fixed rod 22 to be disengaged from the fixed groove 111.

[0043] The telescopic motor 23 improves the automation degree of the transfer barrel access device, facilitates the access work efficiency of the transfer barrel 10, and reduces the work intensity of the operator in accessing the transfer barrel 10.

[0044] Embodiment four:

[0045] Based on the embodiment three, the lifting assembly 20 further comprises: a lifting motor 24, the lifting motor 24 has a lifting shaft that can be selectively moved in the height direction, the lifting motor 24 is connected with the connecting plate 21, and the lifting shaft is connected with the fixed rod 22.

[0046] In some embodiments, the lifting motor 24 is another important component of the lifting assembly 20, the lifting motor 24 is connected with the connecting plate 21, the lifting motor 24 is used to drive the fixed rod 22 to move in the height direction, the lifting motor 24 has a lifting shaft which can be selected to move in the height direction, and the lifting shaft is connected with the fixed rod 22. The lifting motor 24 drives the fixed rod 22 to lift or drop in the height direction through the up-down movement of the lifting shaft thereof. Since the lifting motor 24 is connected with the connecting plate 21 and the lifting shaft is connected with the fixed rod 22, when the lifting motor 24 works, the lifting shaft drives the fixed rod 22 to move up and down, thereby realizing the lifting or dropping of the transfer bucket 10.

[0047] Therefore, the introduction of the lifting motor 24 makes the movement of the transfer bucket 10 in the vertical direction more automatic, further reduces the manual intervention, improves the efficiency and safety of the transfer bucket 10 access operation, and the operator only needs to control the working state of the lifting motor 24 to realize the accurate lifting or dropping of the transfer bucket 10, which simplifies the operation steps. Moreover, the accurate control of the lifting motor 24 ensures the accurate movement position of the fixed rod 22 in the height direction, thereby ensuring the stability of the transfer bucket 10 during the lifting or dropping process. Of course, the lifting motor 24 has high repeatability and can perform the same action multiple times to ensure the consistency of each operation, thereby enhancing the reliability and stability of the transfer bucket access device. At the same time, the automatic vertical movement reduces the physical labor of the operator, especially in the case of frequent lifting or dropping of the transfer bucket 10, which can significantly reduce the burden of the operator.

[0048] According to some embodiments of the present application, the plurality of transfer buckets 10 are stacked in the height direction, the transfer bucket 10 matched with the accommodating groove is the first transfer bucket 10, and the transfer bucket 10 adjacent to the first transfer bucket 10 is the second transfer bucket 10; wherein the lifting shaft has a third state and a fourth state, in the third state, the fixed rod 22 is selectively accommodated in the fixed groove 111 of the second transfer bucket 10; in the fourth state, the fixed rod 22 drives the second transfer bucket 10 to separate from the first transfer bucket 10 in the height direction.

[0049] It can be understood that when the lifting shaft is in the third state and the fixed rod 22 is in the first state, the fixed rod 22 will enter the fixed groove 111 of the second transfer bucket 10, thereby ensuring the stability of the second transfer bucket 10 during the lifting or dropping process, so as to ensure that the second transfer bucket 10 will not slide or tilt during the lifting or dropping process. When the lifting shaft is in the fourth state, the fixed rod 22 drives the second transfer bucket 10 to lift and separate from the first transfer bucket 10, so that the first transfer bucket 10 can move independently. At this time, the operator can take out the first transfer bucket 10.

[0050] It is worth mentioning that after the operator takes out the first transfer bucket 10, the lifting shaft is lowered and the original second transfer bucket 10 is accommodated in the accommodating groove, at this time, the original second transfer bucket 10 is configured as a new first transfer bucket 10.

[0054] It can be understood that the limiting part can be movable in the height direction, here the limiting part can be driven by an electric or pneumatic device, when it is necessary to fix the plurality of transfer buckets 10, the limiting part is movable towards the storage support and contacts and exerts a certain pressure on the top transfer bucket 10, to ensure that all the transfer buckets 10 are firmly fixed on the storage support, when it is necessary to release the fixation, the limiting part is movable away from the storage support to release the pressure on the transfer buckets 10, so that the plurality of transfer buckets 10 can be freely moved.

[0055] Therefore, the introduction of the limiting assembly ensures the stability of the plurality of transfer buckets 10 when they are stacked and stored, prevents the plurality of transfer buckets 10 from toppling or sliding due to external vibration or other factors, ensures the safety of the plurality of transfer buckets 10 when they are stored, and ensures the stability of the transfer buckets 10 when they are stored, thereby reducing the safety accidents caused by the accidental movement of the plurality of transfer buckets 10.
