[0033] refer to Figure 1-Figure 5 As shown, the embodiment of the present solution provides a slag removal robot system for an electric arc furnace, which includes: a mobile vehicle 20, a slag removal mechanism 10 and a power supply component 40;

[0034] The mobile vehicle 20 is movably arranged between a plurality of workstations, and a power supply assembly 30 is arranged on each of the plurality of workstations; the slag removal mechanism 10 is arranged on the mobile vehicle 20, and is used for performing slag removal operation on the ladle of the ore-fired furnace;

[0035] The power taking component 40 is disposed on the mobile vehicle and is electrically connected to the slag scraping mechanism 10 . The power taking component 40 can be selectively electrically connected to the power supply component 30 to provide power to the slag scraping mechanism 10 .

[0036] The slag removal mechanism 10 is a main device that can perform slag removal operations, and can remove bottom slag and floating slag in the iron ladle of the submerged arc furnace. The slag removal mechanism 10 is arranged on a mobile vehicle 20. Among them, the submerged arc furnace can be used to produce alloys such as cadmium iron, ferromanganese, ferrosilicon, silicon manganese, and silicon aluminum.

[0037] The moving vehicle 20 can move on the ground or a similar supporting surface, for example, between various workstations, to move the slag removal mechanism 10 to a target workstation, so that the slag removal mechanism 10 can perform slag removal operations at the target workstation.

[0038] In addition, the power supply component 30 is arranged at the work station, and the mobile vehicle 20 is provided with a power supply component 40 which is electrically connected to the slag scraping mechanism 10 and can cooperate with the power supply component 30. The movement of the mobile vehicle 20 allows the power supply component 40 and the power supply component 30 to be electrically connected to each other, so that the power supply component 30 can provide power to the slag scraping mechanism 10, allowing the slag scraping mechanism 10 to perform slag scraping operations at the work station.

[0039] It can be seen that carrying the slag scraping mechanism 10 by the mobile vehicle 20 can provide the slag scraping mechanism 10 with better mobility, allowing it to switch between various workstations, and the power supply component 30 can provide power to the slag scraping mechanism 10 to ensure its normal operation.

[0040] In this solution, the slag removal robot system of the ore-fired furnace can move between different workstations, which simplifies the operation process, has better flexibility, improves work efficiency, and avoids the safety hazards of using a crane to transfer the ladles.

[0041] In some embodiments, the mobile vehicle 20 moves along the first direction to drive the power extraction component 40 to move along the first direction, and the power extraction component 40 and the power supply component 30 are slidably engaged along the first direction. The mobile vehicle 20 moves along the first direction, and accordingly, the power extraction component 40 moves along the first direction relative to the power supply component 30. During the movement, the two remain slidably engaged to allow the power supply component 30 to provide power to the power extraction component 40. Since the power extraction component 40 can be slidably engaged with the power supply component 30, this also allows the mobile vehicle 20 to move within a certain range along the first direction at the corresponding workstation, thereby increasing the operating range of the slag removal mechanism 10. In particular, the first direction is a horizontal direction. By setting the mutual cooperation structure of the power supply component 30 and the power extraction component 40, the first direction can be perpendicular to the direction of the slag removal mechanism 10 toward the material to be processed, that is, the mobile vehicle 20 is allowed to move laterally relative to the material to be processed.

[0042] Among them, in some embodiments, the power supply assembly 30 includes a plurality of busbars 31 extending along a first direction, and the power collection assembly 40 includes a plurality of current collectors 41 corresponding to the plurality of busbars 31 one by one, and the current collectors 41 are engaged with the busbars 31 and can slide relative to the busbars 31 along the first direction. The current collector 41 can be in slidable contact with the busbar 31, that is, when the two are in contact with each other, the current collector 41 can move along the extension direction (first direction) of the busbar 31, thereby allowing the mobile vehicle 20 and the slag removal mechanism 10 to move in the first direction, thereby increasing the operating range. The current collector 41 can be a carbon brush, or a metal brush or a block conductor. A plurality of busbars 31 spaced apart in the vertical direction can be provided on the power supply assembly 30. In addition, the power supply assembly 30 includes a bracket 32 ​​for supporting the busbar 31, and the bracket 32 ​​is connected to the ground by chemical bolts.

[0043] In some embodiments, the power taking assembly 40 can move toward the power supply assembly 30 relative to the mobile vehicle 20 to engage with the power supply assembly 30, and the power taking assembly 40 moves away from the power supply assembly 30 relative to the mobile vehicle 20 to disengage from the power supply assembly 30. When the mobile vehicle 20 moves to the target station, the power taking assembly 40 can be moved relative to the mobile vehicle 20 so that the power taking assembly 40 moves to a position electrically connected to the power supply assembly 30, so as to allow the power supply assembly 30 to provide power to the power taking assembly 40 and the slag removal mechanism 10. The moving direction of the power taking assembly 40 relative to the mobile vehicle 20 can be a second direction perpendicular to the first direction, and the first direction and the second direction are both horizontal directions perpendicular to the vertical direction. The collector 41 has a certain size range in the vertical direction, allowing the collector 41 to have a certain relative position error in the vertical direction, ensuring that the collector 41 can contact the busbar 31 by moving along the second direction without substantially adjusting the position of the collector 41 in the vertical direction.

[0044] Among them, in some embodiments, each of the workstations is provided with a power supply component 30, and the adjacent power supply components 30 are arranged at intervals. A power supply component 30 is respectively provided on each workstation, and the power supply components 30 are relatively independent of each other and there is a certain interval between them. When the distance between the workstations is large, the extension length of the power supply component 30 can be reduced to reduce the cost. In other embodiments, when the distance between the workstations is small, only a single power supply component 30 can be provided, and a single power supply component 30 extends to each workstation. Of course, in some other embodiments, a plurality of workstations with similar distances can share a power supply component 30, while other workstations with a longer distance can be provided with independent power supply components 30 respectively.

The telescopic drive member 42 can be telescopic to drive the support frame 43 to move relative to the mobile vehicle 20, for example, to move along the second direction, so that it can move toward and away from the power supply assembly 30, so that the collector 41 contacts or disengages from the busbar 31. The telescopic drive member 42 can be an electric cylinder, an oil cylinder, a pneumatic cylinder, etc.

The base 44 is located on the mobile vehicle 20, and it provides a support foundation for the support frame 43 through the slide rail 45. The support frame 43 is arranged on the slide rail 45. Under the driving action of the telescopic drive member 42, the support frame 43 can move toward or away from the power supply assembly 30 on the slide rail 45. Among them, the telescopic drive member 42 is an electric cylinder, and the power supply line on the mobile vehicle 20 can provide power to the electric cylinder.
