[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] Refer to the following Figures 1 to 3 A charging device for a vacuum melting furnace according to some embodiments of the present invention is described.

[0026] like Figure 1 As shown, the vacuum melting furnace charging device provided according to an embodiment of the present invention includes a turret device 10, a trolley device 20 and a silo device 30 arranged in sequence along a first direction, the turret device 10 includes a first bracket 11 for hanging a barrel 12; the trolley device 20 includes a trolley base 21, a moving mechanism 22, and a second bracket 23, the moving mechanism 22 is arranged on the trolley base 21 and connected to the second bracket 23, and is used to drive the second bracket 23 to reciprocate along the first direction and reciprocate along the second direction relative to the trolley base 21, and the second bracket 23 can rotate relative to the trolley base 21; the silo device 30 includes a silo body 31 and a hoisting assembly 32 arranged in the silo body 31; wherein the movement of the moving mechanism 22 can enable the second bracket 23 to hang the barrel 12 on the first bracket 11 on the second bracket 23, and move the barrel 12 into the silo body 31, and the hoisting assembly 32 is used to drive the barrel 12 located in the silo body 31 to approach or move away from a specified position. Thus, automatic feeding and automatic fetching and feeding of the material barrel 12 are realized during the vacuum smelting process, which reduces the labor intensity of workers and improves the feeding efficiency.

[0027] Specifically, during the feeding process, the second bracket 23 is first adjusted so that the second bracket 23 is located at the lowest point along the second direction, and then the motion mechanism 22 drives the second bracket 23 to move along the first direction. When the second bracket 23 moves to the side of the turret device 10, the motion mechanism 22 drives the second bracket 23 to rise to the highest point along the second direction. During the rising process, the second bracket 23 can support the barrel 12, so that the barrel is separated from the first bracket 11 and suspended on the second bracket 23. Then, the motion mechanism 22 drives the second bracket 23 to drive the barrel 12 to return to the middle position along the first direction, and then rotates the second bracket 23 so that the barrel 12 rotates to the side of the silo device 30. The motion mechanism 22 continues to drive the second bracket 23 to move along the first direction, and the barrel 12 filled with materials is sent into the silo device 30. The lifting assembly 32 is used to drive the barrel 12 to rise, so that the barrel 12 is separated from the second bracket 23, so as to add materials to the smelting chamber. After the feeding process is completed, the motion mechanism 22 drives the second bracket 23 to return to the middle position along the first direction.

[0028] Furthermore, by the same logic, during the process of taking the barrel 12, the motion mechanism 22 drives the second bracket 23 to move to the silo device 30 along the first direction, and the hoisting assembly 32 controls the barrel 12 to descend, so that the barrel 12 falls on the second bracket 23. Then, the motion mechanism 22 drives the second bracket 23 to move to the middle position along the first direction, and rotates the second bracket 23 so that the barrel 12 rotates to the side of the turret device 10. At this time, the motion mechanism 22 can be controlled to move so that the second bracket 23 is located at the highest point along the second direction. Then, the motion mechanism 22 continues to drive the second bracket 23 to move to the turret device 10 along the first direction, and the motion mechanism 22 drives the second bracket 23 to descend along the second direction, so that the empty barrel 12 falls on the first bracket 11. After the process of taking the barrel 12 is completed, the motion mechanism 22 drives the second bracket 23 to return to the middle position along the first direction.

[0029] Among them, the horizontal direction along the distribution order of the turret device 10, the trolley device 20 and the silo device 30 is set as the first direction, and the lifting direction of the moving mechanism 22 is set as the second direction; the lifting assembly 32 can drive the barrel 12 in the silo body 31 to rise and fall, so as to approach or move away from the specified position, that is, approach or move away from the smelting chamber, so as to automatically add materials to the smelting chamber or take and deliver the barrel 12.

[0030] like Figure 2As shown, the motion mechanism 22 includes a feeding trolley 221, a first driving part 222 and a lifting mechanism 223. The feeding trolley 221 is arranged on the trolley base 21, and the feeding trolley 221 is used to drive the second bracket 23 to move along the first direction. A sleeve 224 is arranged on the top of the feeding trolley 221, and the second bracket 23 is inserted into the sleeve 224. The second bracket 23 is rotatable relative to the sleeve 224, and is used to rotate the barrel 12 to a desired position by rotating the second bracket 23. Specifically, a support rod is arranged at the bottom of the second bracket 23, and the support rod is inserted into the sleeve 224 in a direction perpendicular to the ground, so that the second bracket 23 can rotate with the support rod as the axis. The worker manually adjusts the barrel 12 so that it is located on one side of the turret device 10 or one side of the silo device 30.

[0031] like Figure 2 As shown, the first driving part 222 is arranged on the trolley base 21, and the trolley base 21 is provided with a guide rail 225 along the first direction. The first driving part 222 is connected to the feeding trolley 221, and is used to drive the feeding trolley 221 to move along the guide rail 225, thereby driving the second bracket 23 to move along the first direction, so that the second bracket 23 drives the barrel 12 to move horizontally.

[0032] The lifting mechanism 223 is arranged on the feeding trolley 221, and includes a support portion 226 inserted in the sleeve 224 and connected to the second bracket 23. The lifting mechanism 223 is used to drive the second bracket 23 to move relative to the sleeve 224 along the second direction, so that the second bracket 23 can drive the bucket 12 to rise and fall, so that the second bracket 23 can take and feed the bucket 12. Specifically, the support portion 226 rises and drives the second bracket 23 to rise along the second direction, and the second bracket 23 supports the bucket 12 to separate from the first bracket 11 and hangs the bucket 12 on the second bracket 23; similarly, the support portion 226 descends and drives the second bracket 23 to descend along the second direction. When the height of the second bracket 23 is lower than that of the first bracket 11, the bucket 12 separates from the second bracket 23 and falls on the first bracket 11. Preferably, the lifting mechanism 223 uses a spiral lift.

[0033] like Figure 2 As shown, the trolley device 20 also includes a first limit assembly 24, which is used to limit the rotation of the second bracket 23 relative to the sleeve 224, thereby locking the second bracket 23 in the rotation direction, so that during the process of adding or taking the material barrel 12, the material barrel 12 is located in a suitable position and the second bracket 23 can be prevented from rotating.

[0034] like Figure 2As shown, in some possible embodiments, the first limit assembly 24 includes a first limit member 241 and a locking cylinder 242, the first limit member 241 is arranged on the sleeve 224, and the first limit member 241 is provided with a limit hole 245, which is used to cooperate with the locking cylinder 242 to achieve the locking function. It is understandable that the number and distribution of the first limit members 241 can be set as needed. Preferably, the two first limit members 241 are respectively arranged on both sides of the top of the sleeve 224 along the first direction, so that when the first limit assembly 24 is locked, the barrel 12 can be located on one side of the turret device 10 or one side of the silo device 30, and two limit holes 245 can also be set on opposite sides of the same limit member, so that when the first limit assembly 24 is locked, the barrel 12 can be located on one side of the turret device 10 or one side of the silo device 30.

[0035] The locking cylinder 242 is disposed on the second bracket 23, and the locking cylinder 242 includes a cylinder body 243 and a piston rod 244. The piston rod 244 can be extended or retracted to be located in the limiting hole 245 or to be separated from the limiting hole 245, so as to realize the locking and unlocking of the second bracket 23 in the rotation direction. It can be understood that the installation positions of the first limiting member 241 and the locking cylinder 242 are not limited here, and the locking cylinder 242 can also be disposed on the sleeve 224, and the first limiting member 241 can be disposed on the second bracket 23. Preferably, the first limiting member 241 is an annular limiting member, and at least one limiting hole 245 is disposed on the first limiting member 241.

[0036] Specifically, during the locking process, the second bracket 23 rotates so that the barrel 12 is located on one side of the silo device 30 or one side of the turret device 10, and the piston rod 244 extends from the cylinder body 243 and passes through the limiting hole 245 to achieve locking of the second bracket 23 in the rotation direction; during the unlocking process, the piston rod 244 retracts from the cylinder body 243 and disengages from the limiting hole 245 to achieve unlocking of the second bracket 23 in the rotation direction.

[0037] like Figure 1 As shown, the turret device 10 also includes a turret base 13 and a second driving unit 14. The second driving unit 14 is disposed on the turret base 13 and connected to the first bracket 11, and is used to drive the first bracket 11 to rotate relative to the turret base 13, so as to automatically rotate the barrel 12 to a desired position. Specifically, a slewing bearing is disposed above the turret base 13, and the slewing bearing is connected to the second driving unit 14. The first bracket 11 is connected above the slewing bearing, so that the second driving unit 14 can drive the first bracket 11 to rotate through the slewing bearing, thereby driving the barrel 12 to rotate to one side of the trolley device 20.

[0038] like Figure 1 and Figure 3As shown, a plurality of support structures 15 are arranged on the circumferential side of the first bracket 11, and the barrel 12 can be suspended on the support structure 15, so that the first bracket 11 can simultaneously suspend a plurality of barrels 12, realizing multiple continuous feeding during the vacuum smelting process. Compared with the existing feeding mechanism which is manual single barrel feeding, the labor intensity of the workers is reduced and the feeding efficiency is improved. It can be understood that the specific number of the support structures 15 is not limited here, and can be three, four, five or other numbers that meet the needs. Preferably, four support structures 15 are arranged on the top of the first bracket 11 along the circumferential direction, and the adjacent support structures 15 are distributed at 90 degrees.

[0039] like Figure 3 As shown, any support structure 15 includes two support plates 151 arranged in parallel, one end of the support plate 151 is connected to the top of the first bracket 11, and is used to suspend the barrel 12 located in the turret device 10, and a through slot 152 is formed between the other ends of the two support plates 151, so that the second bracket 23 can take and deliver the barrel 12. Among them, the second bracket 23 includes a support arm 231 for supporting the barrel 12, and the end of the support arm 231 is suitable for passing through the through slot 152 along the second direction, so that when the second bracket 23 takes and delivers the barrel 12 to the first bracket 11, the support arm 231 can be raised and lowered along the through slot 152, thereby improving the accuracy of sending out or receiving the barrel 12 and avoiding the barrel 12 from falling off.

[0040] Specifically, during the process of taking the material barrel 12, the second bracket 23 is adjusted to be at the lowest point in the second direction, and the second bracket 23 approaches the first bracket 11 along the first direction, so that the end of the support arm 231 is located directly below the through groove 152, and then the second bracket 23 rises along the second direction, lifts the material barrel 12 located on the first bracket 11 and hangs it on the support arm 231, and then the second bracket 23 moves along the first direction away from the turret device 10, and moves the material barrel 12 to the trolley device 20, thereby realizing the operation of taking the material barrel 12 from the turret device 10 to the trolley device 20. During the feeding process of the barrel 12, the second bracket 23 is adjusted to be at the highest point in the second direction, and the second bracket 23 approaches the first bracket 11 along the first direction, so that the end of the support arm 231 is located directly above the through slot 152, and then the second bracket 23 descends along the second direction, and the barrel 12 suspended on the support arm 231 is placed on the first bracket 11, and then the second bracket 23 moves along the first direction away from the turret device 10, thereby realizing the feeding operation of the barrel 12 from the trolley device 20 to the turret device 10.

[0041] like Figure 1As shown, the turret device 10 further includes a first limit switch 16. The first limit switch 16 is disposed on the turret base 13 and is connected to the second driving part 14 for controlling the rotation position of the first support 11. The first limit switch 16 is set to trigger a signal when the first support 11 rotates to a first preset position. Specifically, when the first support 11 drives the material bucket 12 to rotate to one side of the trolley device 20, it reaches the first preset position, and the first limit switch 16 operates to make the second driving part 14 stop working, and the first support 11 stops rotating. Specifically, the first preset position is the position where the first support 11 is located when the material bucket 12 required for feeding rotates to one side of the trolley device 20.

[0042] As Figure 1 shown, the silo device 30 further includes a silo door 33, a vacuum valve 34 and a discharge port 35. The silo door 33 is disposed on one side of the silo body 31 and can be opened and closed relative to the silo body 31 for the material bucket 12 to enter and exit. When the silo door 33 is closed, the silo body 31 is sealed, and the automatic opening, closing and locking of the silo door 33 are realized by the drive of a cylinder. The vacuum valve 34 is disposed on the silo body 31 for maintaining a vacuum atmosphere in the silo body 31 during the feeding process, so as to realize maintaining the vacuum atmosphere in the melting chamber when continuously adding materials. The discharge port 35 is disposed at the bottom of the silo body 31 for connecting to the melting chamber, so that the material bucket 12 can enter the melting chamber through the discharge port 35.

[0043] Specifically, during the feeding process, the inside of the silo body 31 is in an atmospheric state. The silo door 33 is opened, the material bucket 12 suspended on the second support 23 is hung on the lifting assembly 32, the silo door 33 is closed, and the vacuum valve 34 is used to evacuate the silo body 31. After the evacuation is completed, the vacuum valve 34 is closed, a protective gas with the same pressure as that in the melting chamber is filled into the silo body 31, then the vacuum valve 34 is opened again, the lifting assembly 32 is used to drive the material bucket 12 to descend, the discharge port 35 is opened, and the material in the material bucket 12 is added to the crucible in the melting chamber through the discharge port 35. Finally, the lifting assembly 32 drives the material bucket 12 to rise and return to the silo body 31, the discharge port 35 and the vacuum valve 34 are closed, and the feeding process is completed.

[0044] During the process of taking the material bucket 12, first, the discharge port 35 is closed, air is introduced into the silo body 31, and after the inside of the silo body 31 returns to the atmospheric state, the silo door 33 is opened. The feeding trolley 221 moves along the first direction to the position of the silo device 30, and the lifting assembly 32 is used to adjust the height of the material bucket 12 along the second direction so that the material bucket 12 falls on the second support 23, and the material bucket 12 is moved out of the silo device 30 by the feeding trolley 221.

[0045] As Figure 1As shown, the hoisting assembly 32 includes a pulley mechanism 321 and a sling 322 wound around the pulley mechanism 321, which is used to drive the barrel 12 in the silo device 30 to move along the second direction to achieve automatic feeding, wherein a reducer is used to drive the pulley mechanism 321 to drive the sling 322 to move up and down. The barrel 12 located in the silo body 31 is suitable for connecting with the sling 322. Preferably, the sling 322 is made of a metal chain that can bear the weight of the barrel 12. The free end of the sling 322 is provided with a hook for hanging the barrel 12.

[0046] Specifically, the pulley mechanism 321 includes a driving wheel and an idler wheel. The driving wheel is connected to the reducer through a connecting shaft. The fixed end of the sling 322 is wrapped around the driving wheel, and the free end is wrapped around the idler wheel to suspend the bucket 12 to achieve the lifting height of the bucket 12 along the second direction.

[0047] like Figure 1 As shown, the silo device 30 further includes a second limit switch 36, which is disposed inside the silo body 31 and connected to the hoisting assembly 32, and is used to control the lifting height of the hoisting assembly 32. The second limit switch 36 is configured to trigger a signal when the sling 322 reaches a second preset position. Specifically, when the hoisting assembly 32 drives the barrel 12 to rise to the silo door 33 or descend to the smelting chamber, the second preset position is reached, and the second limit switch 36 operates to stop the hoisting assembly 32, and the barrel 12 stops rising or descending.
