[0028] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments.

[0029] An embodiment of the present application provides a piercing robot for opening the eyes of a submerged arc furnace. The schematic structural diagram of the piercing robot is as Figure 1 shown and includes: a traveling mechanism 1, a piercing mechanism 2, and a power-on mechanism 3; the traveling mechanism 1 travels on a circular track on the outer periphery of the submerged arc furnace. The traveling mechanism 1 includes a mounting frame 11 and traveling legs 12. The two traveling legs 12 are respectively connected to both ends of the mounting frame 11 and are used to cooperate with the circular track for traveling; the piercing mechanism 2 includes a track beam 21, a piercing component 22, and a multi-axis motion structure 23. The track beam 21 is arranged at the bottom of the mounting frame 11 and is located between the two traveling legs 12; the piercing component 22 is movably connected to the track beam 21, and the multi-axis motion structure 23 is arranged between the track beam 21 and the piercing component 22 and is used to drive the piercing component 22 to move so as to align with the furnace eye of the submerged arc furnace; the power-on mechanism 3 is arranged on the traveling mechanism 1 and is electrically connected to the piercing component 22. The power-on mechanism 3 can selectively contact the power supply copper bar of the submerged arc furnace and is used to supply power to the piercing component 22.

[0030] As Figure 1As shown in the figure, the burn-through robot according to the embodiment of the present application is used for the eye-opening operation of industrial silicon or calcium carbide submerged arc furnaces. However, the embodiment of the present application does not limit the type of submerged arc furnace for specific applications. The traveling mechanism 1 includes a mounting frame 11 and traveling legs 12. The mounting frame 11 is a frame structure, and the length direction of the mounting frame 11 is generally consistent with the extending direction of the annular track. The two traveling legs 12 are respectively located at both ends of the mounting frame 11, and each traveling leg 12 is in rolling cooperation with the two guide rails of the annular track to drive the burn-through mechanism 2 to travel along the annular track. The burn-through mechanism 2 is integrally arranged at the central position of the bottom of the mounting frame 11. Among them, the track beam 21 is fixedly arranged on the mounting frame 11, and the track beam 21 is located between the two traveling legs 12. The extending direction of the track beam 21 intersects with the length direction of the mounting frame 11. The burn-through component 22 is located below the track beam 21 and can move relative to the track beam 21, such as forward, backward, pitching and slewing actions, so that the burn-through component 22 can be aligned with the furnace eye of the submerged arc furnace to perform the eye-opening operation on the furnace eye. The multi-axis motion structure 23 is arranged between the track beam 21 and the burn-through component 22 and is used to drive the burn-through component 22 to perform multi-axis motion, so that the burn-through component 22 can be aligned with the furnace eye of the submerged arc furnace, thereby completing the eye-opening operation of the burn-through component 22 on the submerged arc furnace. The power-on mechanism 3 is arranged on one side of the traveling mechanism 1. The power-on mechanism 3 is electrically connected to the burn-through component 22. When the eye-opening operation needs to be performed, the power-on mechanism 3 can contact the power supply copper busbar around the submerged arc furnace to supply power to the burn-through component 22; when the eye-opening operation is completed, the power-on mechanism 3 is separated from the power supply copper busbar to stop supplying power to the burn-through component 22. At this time, the traveling mechanism 1 can drive the burn-through component 22 to move, thereby improving the safety of the eye-opening operation.

[0031] In the embodiment of the present application, the traveling mechanism travels along the annular track of the submerged arc furnace to carry the burn-through component and move left and right on the annular track, so that the burn-through component can move to the position of the furnace eye; the multi-axis motion structure is arranged between the track beam and the burn-through component to drive the burn-through component to perform actions such as forward, backward, pitching and slewing, so that the burn-through component can move flexibly to align with the furnace eye and perform the eye-opening operation, thereby realizing that the embodiment of the present application replaces manual eye-opening operation, which can not only greatly reduce the labor intensity and safety risks of the operators, thus avoiding affecting the physical health of the operators, but also greatly improve the working efficiency and automation level of the eye-opening operation.

[0032] In an embodiment of the present application, as Figure 1 and Figure 2As shown, the multi-axis motion structure 23 includes a moving vehicle 24 and a first driving component 25. The moving vehicle 24 is slidably arranged at the bottom of the track beam 21 and can move along the axial direction of the track beam 21. The burner component 22 is suspended at the bottom of the moving vehicle 24. The first driving component 25 is arranged on the track beam 21 and is connected to the moving vehicle 24 for driving the moving vehicle 24 to move. Specifically, a plurality of sliding wheels are arranged on the top of the moving vehicle 24. The track beam 21 is, for example, of I-beam steel structure. The moving vehicle 24 is in rolling cooperation with the top surface of the bottom plate of the track beam 21 through the plurality of sliding wheels, that is, the moving vehicle 24 is slidably arranged at the bottom of the track beam 21. Further, a plurality of guiding wheels are also arranged on both sides of the moving vehicle 24. The plurality of guiding wheels are respectively in rolling cooperation with both side surfaces of the bottom plate so that the moving vehicle 24 moves along the axial direction of the track beam 21. The burner component 22 is arranged at the bottom of the moving vehicle 24. The moving vehicle 24 can drive the burner component 22 to move back and forth so that the carbon rod of the burner component 22 moves to the furnace eye of the submerged arc furnace. The first driving component 25 is arranged on the track beam 21 and is connected to the moving vehicle 24 to drive the moving vehicle 24 to move back and forth relative to the track beam 21. With the above design, the embodiment of the present application can realize the back-and-forth movement of the burner component 22 through a relatively simple structure, thereby greatly reducing the application and maintenance costs of the present application.

[0033] In an embodiment of the present application, as Figure 1 and Figure 2As shown in the figure, the first driving assembly 25 includes a driver 251, a transmission wheel 252 and a flexible transmission member 253. The driver 251 and the transmission wheel 252 are respectively arranged at both ends of the track beam 21. The flexible transmission member 253 is arranged around the output end of the driver 251 and the outer periphery of the transmission wheel 252, and both ends of the flexible transmission member 253 are respectively connected to both ends of the moving vehicle 24. Specifically, the driver 251 can be implemented by a motor. The driver 251 is arranged at the rear end of the track beam 21, and a driving wheel is also arranged at the rear end of the track beam 21. The driver 251 is in transmission connection with the driving wheel, and the driving wheel is specifically a sprocket. The transmission wheel 252 is implemented by a sprocket. The transmission wheel 252 is arranged on one side of the front end of the track beam 21, and the transmission wheel 252 is arranged on the same side as the driving wheel. The flexible transmission member 253 is a chain. The flexible transmission member 253 is wound around the outer peripheries of the transmission wheel 252 and the driving wheel. Both ends of the flexible transmission member 253 are respectively connected to the front and rear ends of the moving vehicle 24. The driver 251 drives the moving vehicle 24 to move back and forth through the flexible transmission member 253. With the above design, not only can the transmission stability and transmission efficiency of the embodiment of the present application be effectively improved, but also the failure rate can be greatly reduced and the service life can be extended. It should be noted that the embodiment of the present application does not limit the specific implementation manner of the first driving assembly 25. For example, the driver 251 can be a hydraulic motor, and the flexible transmission member 253 can be implemented by a high-temperature resistant belt. Or the driver 251 can use a telescopic cylinder to directly drive the moving vehicle 24 to move back and forth. Therefore, the embodiment of the present application is not limited thereto, and those skilled in the art can adjust the settings according to the actual situation.

[0034] In an embodiment of the present application, as Figure 1 and Figure 2 shown, the multi-axis motion structure 23 further includes a slewing assembly 26. Part of the slewing assembly 26 is fixedly connected to the moving vehicle 24, and part of the slewing assembly 26 is hinged to the piercing torch assembly 22. The piercing torch assembly 22 can slewing and pitch relative to the moving vehicle 24. Specifically, the slewing assembly 26 is, for example, a slewing bearing. The inner ring of the slewing assembly 26 is fixed to the bottom of the moving vehicle 24, and a lifting lug is arranged at the bottom of the outer ring of the slewing assembly 26. The piercing torch assembly 22 is hinged through the lifting lug, so that the piercing torch assembly 22 can slewing relative to the moving vehicle 24, and the piercing torch assembly 22 can pitch relative to the moving vehicle 24. Since the piercing torch assembly 22 can slewing and pitch relative to the moving vehicle 24, the movement of the piercing torch assembly 22 is more flexible, and the structure is relatively simple, thereby reducing the maintenance and application costs, and improving the economic benefits of the embodiment of the present application. It should be noted that the embodiment of the present application does not limit the specific implementation manner of the slewing assembly 26, and those skilled in the art can adjust the settings according to the actual situation.

[0035] In an embodiment of the present application, as Figure 1 andFigure 2 As shown, the multi-axis motion structure 23 further includes a second driving component 27 and a third driving component 28. A tail beam 241 is provided at the rear end of the mobile vehicle 24. The second driving component 27 is connected to the tail beam 241 and is connected to the tail end of the piercing torch assembly 22 through the third driving component 28. The second driving component 27 and the third driving component 28 cooperate to drive the piercing torch assembly 22 to perform rotary and pitching actions.

[0036] As Figure 1 and Figure 2 shown, a tail beam 241 is provided at the rear end of the mobile vehicle 24. The tail beam 241 is generally flush with the tail end of the piercing torch assembly 22, but the present application does not limit the specific length of the tail beam 241. The second driving component 27 is provided on the tail beam 241 and is used to drive the rotary action of the piercing torch assembly 22. The third driving component 28 is provided on the piercing torch assembly 22 and is connected to the second driving component 27 and is used to drive the pitching action of the piercing torch assembly 22. However, the embodiments of the present application are not limited thereto. For example, the second driving component 27 and the third driving component 28 can be provided separately, that is, both are provided between the tail beam 241 and the piercing torch assembly 22, and the above functions can also be achieved. Further, the second driving component 27 and the third driving component 28 can be implemented by electric push rods, telescopic oil cylinders or cylinders, which not only makes the structure of the embodiments of the present application simple and reliable, but also can effectively reduce the application and maintenance costs. With the above design, the embodiments of the present application can realize the automatic control of the actions of the piercing torch assembly 22, thereby effectively improving the automation and intelligent level of the embodiments of the present application.

[0037] In an embodiment of the present application, as Figure 2As shown, both the second drive assembly 27 and the third drive assembly 28 are lead screw structures. The axial direction of the second drive assembly 27 is orthogonally arranged with the axial direction of the tail beam 241. The third drive assembly 28 is arranged on the piercer assembly 22, and the screw of the third drive assembly 28 is connected to the nut of the second drive assembly 27. Specifically, both the second drive assembly 27 and the third drive assembly 28 are lead screw structures. The second drive assembly 27 is arranged at the bottom of the tail beam 241, and the axial direction of the lead screw intersects with the axial direction of the tail beam 241. The third drive assembly 28 is connected to the tail end of the piercer assembly 22 through a support, and the lead screw of the third drive assembly 28 is connected to the second drive assembly 27, for example, connected to the nut of the second drive assembly 27. In practical applications, when the second drive assembly 27 starts, it can drive the third drive assembly 28 to move, thereby driving the piercer assembly 22 to perform a rotary motion. When the third drive assembly starts, it can drive itself to move relative to the second drive assembly 27, thereby driving the piercer assembly 22 to perform a pitching motion. With the above design, not only is the structure of the embodiment of the present application relatively simple, but also the movement amplitude of the piercer assembly 22 can be accurately controlled. Further, since both the second drive assembly 27 and the third drive assembly 28 are arranged at the tail end of the piercer assembly 22, both are far from the heat source, thereby greatly extending the service life and reducing the failure rate.

[0038] In an embodiment of the present application, as Figure 2 shown, the multi-axis motion structure 23 further includes a quick-release component. The quick-release component is arranged between the second drive assembly 27 and the third drive assembly 28, and / or the quick-release component is arranged between the third drive assembly 28 and the piercer assembly 22. Specifically, the quick-release component can be a threaded fastening component or a connecting pin component. The quick-release component is arranged between the second drive assembly 27 and the third drive assembly 28, enabling the two to be quickly disassembled and separated, so as to realize the manual operation of the piercer assembly 22, thereby improving the flexibility of the embodiment of the present application. Optionally, the quick-release component is arranged between the third drive assembly 28 and the piercer assembly 22, enabling the separation of the third drive assembly 28 and the piercer assembly 22, so as to realize the manual operation of the piercer assembly 22, which not only improves the flexibility of the embodiment of the present application, but also makes the manual operation more convenient. Therefore, the embodiment of the present application does not limit the setting position of the quick-release component. For example, the quick-release component is arranged between the second drive assembly 27, the third drive assembly 28 and the piercer assembly 22. Therefore, the embodiment of the present application is not limited thereto, and those skilled in the art can adjust the setting according to the actual situation.

[0039] In an embodiment of the present application, as Figure 2As shown, the first drive assembly 25 includes an electromagnetic clutch 254, which is used to selectively disconnect the power transmission between the first drive assembly 25 and the mobile vehicle 24. Optionally, the tail end of the burner assembly 22 is also provided with a holding member 221, and the holding member 221 is connected to the tail end of the burner assembly 22 by a quick release structure, which is used to control the movement of the burner assembly 22 under the action of an external force. Specifically, the first drive assembly 25 also includes an electromagnetic clutch 254, which is arranged on the outside of the drive wheel and is connected to the driver 251 in a transmission connection. The electromagnetic clutch 254 can selectively disconnect the power transmission between the driver 251 and the drive wheel to disconnect the power transmission between the first drive assembly 25 and the mobile vehicle 24, thereby further improving the convenience and portability of manual operation. Further, in the embodiment of the present application, when the power is off, the electromagnetic clutch 254 can be automatically disconnected, which is convenient for manual operation of the burner assembly 22, thereby further improving the convenience of operation. The holding piece 221 is designed as a handle that is easy to operate manually, so that the operator can hold it easily. The bottom of the holding piece 221 can be retractably inserted into the tail end of the burner assembly 22, and can be detachably arranged with the tail end of the burner assembly 22. A positioning pin and a positioning hole can be arranged between the two, so that the holding piece 221 can be adjusted and disassembled, thereby greatly improving the convenience of operation to prevent the effect of mechanical interference.

[0040] In one embodiment of the present application, Figure 3 As shown, two walking wheels 13 are provided at the bottom ends of the two walking legs 12, and the two walking wheels 13 are used to roll with the two guide rails of the circular track respectively; guide wheels 14 are provided on the two walking legs 12, and the two guide wheels 14 are arranged diagonally, and are used to roll with the outer side surfaces of the two guide rails. Specifically, the two walking legs 12 both adopt the same frame structure, and are installed at the bottom of the mounting frame 11 in a symmetrical and mirrored manner, thereby reducing the application and manufacturing costs. The two walking legs 12 are connected to the mounting frame 11 by bolts, and an adjustment block is provided between the two. By providing different numbers of adjustment blocks, the height of the mounting frame 11 can be adjusted to adapt to burner assemblies 22 of different heights, thereby improving the applicability and scope of application of the embodiments of the present application. A guide wheel 14 is provided on one side of the walking leg 12. The guide wheel 14 is provided in the direction of travel of the walking wheel 13 through a support rod and is located on one side of the direction of travel. Since the two walking legs 12 are symmetrical and mirror-imaged, the two guide wheels 14 can not only guide the front-to-back direction of the walking mechanism 1, but also guide the left-to-right direction of the walking mechanism 1, that is, the two guide wheels 14 are arranged diagonally and roll with the outer side surfaces of the two guide rails of the circular track. With the above design, due to the design of the guide wheel 14, not only can the walking mechanism 1 be effectively guided to prevent the walking mechanism 1 from leaving the circular track, but also the application and manufacturing costs can be greatly reduced.

[0041] In an embodiment of the present application, as Figure 3 shown, the traveling mechanism 1 further includes a fourth driving component 15, and the fourth driving component 15 is disposed on the traveling leg 12 and is in transmission connection with any one of the traveling wheels 13. Specifically, the fourth driving component 15 is disposed on any one of the traveling legs 12 and is drivingly connected to any one of the traveling wheels 13 on the traveling leg 12. The fourth driving component 15 adopts a driving component such as an electric motor or a hydraulic motor. With the above design, since the fourth driving component 15 is only in transmission connection with a certain traveling wheel 13, the control logic of the embodiment of the present application is simple, and there is no need to consider the synchronous driving between the traveling wheels 13, thereby improving the traveling stability and reducing the control difficulty. Optionally, an insulating backing plate may be provided between the traveling leg 12 and the traveling wheel 13 to prevent the leakage of electricity from the burner assembly 22 and cause on-site safety risks, thereby improving the safety of the entire application.

[0042] In an embodiment of the present application, as Figure 4 shown, the power-on mechanism 3 includes a mounting plate 31, a fifth driving component 32 and a power-on copper bar 33. The mounting plate 31 is disposed on one side of the traveling mechanism 1; the fifth driving component 32 is disposed on the mounting plate 31 and is connected to the power-on copper bar 33 for driving the power-on copper bar 33 to move up and down to selectively contact or separate from the power supply copper bar. Specifically, the power-on mechanism 3 is integrally disposed on the left or right side of the traveling mechanism 1, but the embodiment of the present application is not limited thereto, and those skilled in the art can adjust the setting according to the actual situation. The power-on mechanism 3 includes a mounting plate 31, a fifth driving component 32 and a power-on copper bar 33. The mounting plate 31 is disposed on the left side of the frame structure and extends in the vertical direction. The fifth driving component 32 is located on one side of the mounting plate 31, and the telescopic rod of the fifth driving component 32 passes through the mounting plate 31 and is connected to the power-on copper bar 33. The fifth driving component 32 drives the power-on copper bar 33 to move up and down through the telescopic action, so that the power-on mechanism 3 selectively contacts or separates from the power supply copper bar, thereby realizing the power supply or power-off of the burner assembly 22. With the above design, the structure of the embodiment of the present application is simple and easy to use, thereby further reducing the failure rate and extending the service life.

[0043] In an embodiment of the present application, as Figure 4As shown, the power-on mechanism 3 further includes a detector 34. The detector 34 is arranged on the mounting plate 31 and is used to detect whether the power-on copper bar 33 is separated from the power supply copper bar. Specifically, the fifth driving component 32 adopts a lead screw structure for example. The top end of the lead screw of the fifth driving component 32 is connected to the bottom of the power-on copper bar 33, and the detector 34 is arranged at a certain distance at the bottom end thereof. The detector 34 specifically adopts a travel switch. When the lead screw descends to a certain position, that is, when the power-on copper bar 33 is completely separated from the power supply copper bar, the bottom end of the lead screw touches the detector 34. At this time, the traveling mechanism 1 can travel. The specific implementation method can adopt a linkage method or be realized by a controller.
