Description

Technical Field

[0001] This utility model relates to the field of top-blown furnace technology, specifically to a machine vision-based gun adjustment system for top-blown furnaces. Background Technology

[0002] When the top-blown furnace is shut down, it is necessary to collect image information of the spray guns and the molten surface inside the furnace. In actual operation, this is often done manually or by using a telescopic endoscope. Manual observation poses a great safety hazard, while the telescopic endoscope, after being inserted from the top of the top-blown furnace, can only collect information of a local area directly below it and cannot be adjusted, which is a great limitation. Therefore, it is particularly important to design a machine vision-based gun adjustment system for top-blown furnaces to solve the above problems. Summary of the Invention

[0003] To solve the above problems, this utility model designs a top-blown furnace machine vision gun adjustment system. Through the combination of a movable structure, a horizontally adjustable mechanism, and an obliquely adjustable mechanism, the camera part of the high-temperature resistant endoscope can swing freely back and forth and left and right inside the furnace, which greatly improves the imaging range, makes the collected graphic information more complete, and increases its practicality.

[0004] To solve the above-mentioned technical problems, this utility model provides a machine vision gun adjustment system for a top-blown furnace, characterized in that it includes an XY-axis advance / retract mechanism mounting base, a high-temperature resistant endoscope device, a telescopic cylinder, a cylinder mounting base, and a high-temperature resistant endoscope device mounting base. The XY-axis advance / retract mechanism mounting base is connected to the top of the top-blown furnace via a movable structure. The high-temperature resistant endoscope device is mounted on the high-temperature resistant endoscope device mounting base, and the camera part of the high-temperature resistant endoscope device passes through the high-temperature resistant endoscope device mounting base and faces the insertion hole on the top of the top-blown furnace. The high-temperature resistant endoscope device mounting base is connected to the cylinder mounting base via the telescopic cylinder.

[0005] Furthermore, the movable structure includes a double-clamp base and a spherical universal valve. The spherical universal valve is installed on the top of the top-blown furnace via the double-clamp base. The XY-axis forward and backward mechanism mounting base is connected to the spherical universal valve and can swing with the spherical universal valve. A through hole is provided at the center of the spherical universal valve to facilitate the passage of a high-temperature resistant endoscope device. The through hole is directly opposite the insertion hole. Under the action of the telescopic cylinder, the camera part of the high-temperature resistant endoscope device passes through the through hole and the insertion hole in sequence and extends into the top-blown furnace.

[0006] Furthermore, the insertion hole is a frustum-shaped hole.

[0007] Furthermore, the high-temperature resistant endoscope device mounting base is connected to the XY-axis advance and retreat mechanism mounting base via a horizontally adjustable mechanism 6, and the XY-axis advance and retreat mechanism mounting base is connected to the top of the top-blown furnace via an obliquely adjustable mechanism 7. The telescopic cylinder is movably connected to the cylinder mounting base.

[0008] Furthermore, an image collection center module 10 is fixed on the cylinder mounting base, and the high-temperature resistant endoscope device is electrically connected to the image collection center module.

[0009] With the above structure, this utility model, through the combination of the movable structure, the horizontally adjustable mechanism and the obliquely adjustable mechanism, allows the camera part of the high-temperature resistant endoscope device to swing freely back and forth and left and right inside the furnace, greatly improving the imaging range and making the collected graphic information more complete; in addition, this design also has the advantages of simple structure, easy manufacturing and practical efficiency. Attached Figure Description

Detailed Implementation

[0013] like Figure 1 The illustrated top-blown furnace machine vision nozzle adjustment system includes an XY-axis forward / retractable mechanism mounting base 3, a high-temperature resistant endoscope device 4, a telescopic cylinder 5, a cylinder mounting base 8, and a high-temperature resistant endoscope device mounting base 9. The XY-axis forward / retractable mechanism mounting base is connected to the top of the top-blown furnace via a movable structure. The high-temperature resistant endoscope device 4 is mounted on the high-temperature resistant endoscope device mounting base, with its camera passing through the mounting base and facing an insertion hole at the top of the top-blown furnace. The high-temperature resistant endoscope device mounting base is connected to the cylinder mounting base via the telescopic cylinder. During operation, the telescopic cylinder is activated to extend the camera of the high-temperature resistant endoscope device into the top-blown furnace to acquire image information. Based on the acquired image information, an algorithm is used to determine the distance between the nozzle and the copper liquid surface. This design has the advantages of simple structure, ease of manufacture, and high efficiency.

[0014] like Figure 1The movable structure shown includes a double-clamp base 1 and a spherical universal valve 2. The spherical universal valve is mounted on the top of the top-blown furnace via the double-clamp base. The XY-axis forward / backward mechanism mounting base 3 is connected to the spherical universal valve and can swing with it. A through hole is provided at the center of the spherical universal valve to facilitate the passage of a high-temperature resistant endoscope device. The through hole is directly opposite the insertion hole. The camera part of the high-temperature resistant endoscope device passes through the through hole and the insertion hole in sequence under the action of the telescopic cylinder and extends into the top-blown furnace. The insertion hole is a frustum-shaped hole. The high-temperature resistant endoscope device mounting base is connected to the XY-axis forward / backward mechanism mounting base via a horizontally adjustable mechanism 6. The XY-axis forward / backward mechanism mounting base is connected to the top of the top-blown furnace via an obliquely adjustable mechanism 7. The telescopic cylinder is movably connected to the cylinder mounting base. This invention, through a movable structure combined with a horizontally adjustable mechanism and an obliquely adjustable mechanism, allows the camera unit of the high-temperature resistant endoscope to swing freely back and forth and left and right inside the furnace, greatly increasing the imaging range and making the collected graphic information more complete.

[0015] like Figure 1 The cylinder mounting base shown also has an image collection center module 10 fixed on it, and the high-temperature resistant endoscope device is electrically connected to the image collection center module; the high-temperature resistant endoscope device is also equipped with air cooling and water cooling devices.

[0016] The beneficial effects of the above-described structure in this utility model are as follows:

[0017] 1. When the air supply is stopped, the system can automatically identify the height of the spray gun from the molten liquid surface. After transmitting this data to the DCS system, it can guide the operator to perform the gun release operation.

[0018] 2. When the furnace is shut down, the condition of the spray guns inside the furnace, such as slag buildup, deformation, and wear, is clearly displayed, which makes it easier for operators to make judgments and replace the guns.

[0019] 3. The expanded camera range facilitates gun adjustment and shortens the time required for gun adjustment during downtime.

[0020] 4. Improve the accuracy of spray gun adjustment and avoid the experience error of estimating the height of the spray gun by human eye.

[0021] 5. Reduce the safety hazards posed by high-temperature molten metal to manual gun inspection.
