In the process of adjusting the position of the oxygen lance 7, the oxygen lance 7 is moved to the upper side of the oxygen lance hole 8 through the displacement mechanism, then the oxygen lance 7 is lowered, at the moment, the pushing mechanism drives the adjusting circular ring 4 to horizontally move, the oxygen lance 7 passes through the adjusting circular ring 4, the adjusting circular ring 4 limits the oxygen lance 7, and then the oxygen lance hole 8 can be well aligned when the oxygen lance 7 is lowered to the oxygen lance hole 8, the whole process does not need manual operation, the adjusting speed is high, and the adjusting precision is high.
In an alternative embodiment, the pushing mechanism comprises a hydraulic cylinder 2, the hydraulic cylinder 2 is arranged on the adjusting platform 1, and a hydraulic push rod 3 of the hydraulic cylinder 2 is connected with the adjusting ring 4.
It should be noted that the hydraulic pushrods 3 of the hydraulic cylinders 2 extend horizontally and are connected to the adjusting ring 4.

In an alternative embodiment, the diameter of the adjustment ring 4 is larger than the muzzle diameter of the oxygen lance 7.
For example, the muzzle diameter of lance 7 is 27.3 cm and the diameter of adjustment ring 4 is 35 cm, so that lance 7 easily passes through adjustment ring 4.
In an alternative embodiment, the inside of the adjusting ring 4 is provided with a high temperature resistant rubber layer.
The inner lining of the adjusting ring 4 wraps high-temperature-resistant rubber, so that the oxygen lance 7 can be prevented from being scratched and abraded when the oxygen lance 7 passes through the adjusting ring 4.
In an alternative embodiment, the automatic adjusting device of the converter oxygen lance further comprises a laser range finder platform 5, a laser range finder 6 and a controller; the laser range finder platform 5 is arranged on the adjustment platform 1, the height of the laser range finder platform 5 is higher than that of the adjustment platform 1, the laser range finder 6 is arranged on the laser range finder platform 5, the laser range finder 6 faces the oxygen lance 7, and the laser range finder 6, the pushing mechanism and the displacement mechanism are all electrically connected with the controller.

When the laser range finder 6 detects that the actual data exist in 20 cm to 60 cm, the oxygen lance 7 is lowered to the position of the adjusting platform 1, the controller sends out an oxygen lance 7 lowering stop instruction, and at the moment, the controller starts the hydraulic cylinder 2 to adjust the position of the oxygen lance 7 according to the feedback data, and the adjusting range is within 2 cm. If the oxygen lance 7 is lifted, the data of the laser range finder 6 is displayed at infinity, and the program is set so that the oxygen lance 7 is not below, and adjustment is not needed. In order to ensure that the laser range finder 6 can accurately measure the position of the oxygen lance 7, a rectangular reflector 9 is welded near the laser range finder 6 on the oxygen lance 7, the laser spot of the laser range finder 6 is aligned to the center position of the reflector 9, the length of the reflector 9 is 10 cm, the width of the reflector 9 is 5 cm, and the reflector 9 can accurately reflect laser signals when the oxygen lance 7 swings back and forth so as to prevent inaccurate signal feedback and inaccurate signal feedback of the laser range finder 6 when the oxygen lance 7 swings back and forth; the height difference between the laser rangefinder 6 and the hydraulic cylinder 2 is 50 cm.
The controller controls the displacement mechanism to operate, drives the displacement mechanism to drive the oxygen lance 7 to descend, and when the laser range finder 6 detects the oxygen lance 7, the controller controls the pushing mechanism to move the adjusting ring 4 in place, so that the oxygen lance 7 can pass through the adjusting ring 4 until the oxygen lance 7 stretches into the oxygen lance hole 8.
In an alternative embodiment, the laser rangefinder 6 sends an alarm signal to the controller upon detecting that the distance from the lance 7 exceeds a preset distance.
When the laser detection detects that the distance between the laser detection device and the surface of the oxygen lance 7 is 25 cm, the oxygen lance 7 has no deviation and can accurately descend into the oxygen lance hole 8; when the preset distance is 37 cm and the laser detection detects that the distance between the laser detection device and the surface of the oxygen lance 7 exceeds 37 cm, the oxygen lance 7 is large in descending deviation, and at the moment, the controller controls the displacement mechanism to stop descending of the oxygen lance 7 so as to prevent the oxygen lance 7 from crashing the adjusting ring 4.
When the laser range finder 6 detects that the distance between the laser range finder 6 and the surface of the oxygen lance 7 is greater than or less than 25 cm, actual data measured by the laser range finder 6 is required to be fed back to the controller, a step proportional valve is recognized and started through program recognition, the hydraulic push rod 3 of the hydraulic cylinder 2 stretches out or contracts, and the oxygen lance 7 is driven to be adjusted through the adjusting ring 4 until the laser range finder 6 detects that the distance between the laser range finder 6 and the surface of the oxygen lance 7 is 25 cm; the hydraulic push rod 3 is normally arranged at the middle position of the hydraulic cylinder 2, so that the position of the oxygen lance 7 can be conveniently adjusted back and forth by the hydraulic push rod 3.
In an alternative embodiment, the displacement mechanism comprises a traversing carriage, the oxygen lance 7 is arranged on the traversing carriage, and the traversing carriage is used for driving the oxygen lance 7 to horizontally move.
The oxygen lance 7 is transversely moved from a waiting position to a descending position by the transverse moving trolley, a limiting device is arranged at the descending position of the transverse moving trolley to play a role in commanding the transverse moving trolley to stop, and the transverse moving trolley stops descending the oxygen lance 7 at the position until the oxygen lance 7 descends to the oxygen lance hole 8. Because of equipment factors such as sideslip dolly band-type brake, the sideslip dolly sometimes can cross the decline position and park, causes oxygen rifle 7 to go out of range. The laser range finder 6 transmits feedback data to the controller, and the controller commands the oxygen lance 7 to move back again in a slow traversing way, so that the oxygen lance 7 moves until the distance between the surface of the oxygen lance 7 and the laser range finder 6 is 25 cm.
In other embodiments, the traversing carriage may be replaced with other traversing drive mechanisms.
In an alternative embodiment, the displacement mechanism further comprises a lifting trolley 13, a lifting guide frame 11, a steel wire rope, a pulley 12 and a driving piece; the lifting guide frame 11 is fixed on the transverse moving trolley, the lifting trolley 13 is in sliding fit with the lifting guide frame 11, the oxygen lance 7 is connected with the lifting trolley 13, the steel wire rope is wound on the pulley 12 and is connected with the lifting trolley 13, the driving piece is arranged on the lifting guide frame 11 and is in transmission connection with the pulley 12.
It should be noted that the driving member may be a driving motor, and when the oxygen lance 7 needs to be driven to descend, the driving member drives the pulley 12 to rotate, the steel wire rope descends, the lifting trolley 13 descends along with the steel wire rope, and the oxygen lance 7 descends along with the lifting trolley 13. The oxygen lance 7 is arranged on a clamping seat of the lifting trolley 13 and is fixed by an oxygen lance fixing bolt 10, and the oxygen lance 7 cannot shake or rotate automatically.
In an alternative embodiment, a guide rail is vertically arranged on the lifting guide frame 11, and the lifting trolley 13 is in sliding fit with the guide rail.
According to the theory of object kinematics, the swing amplitude of an object is related to the weight and the length of the object, and the larger the weight is, the longer the length is, and the smaller the swing amplitude is. According to this principle, the swing amplitude of the oxygen lance 7 is very small in the actual forward, backward, leftward and rightward directions in the slow descending process at the speed of 4 m/min, and the swing amplitude of the oxygen lance 7 is smaller than 3 cm in the actual measurement, so that the descending speed of the oxygen lance 7 is set to be 4 m/min, and the lifting trolley 13 descends along the guide rails at the two sides, so that the wire rope can be prevented from being wound automatically and the swing amplitude can be limited.
In the process that the lifting trolley 13 drives the oxygen lance 7 to descend, the lifting trolley 13 is in sliding fit with the guide rail, so that the stability of the oxygen lance 7 in the lifting process can be improved.
In summary, the embodiment of the invention provides an automatic adjusting device for a converter oxygen lance, in the process of adjusting the position of the oxygen lance 7, the oxygen lance 7 is moved to the upper side of the oxygen lance hole 8 by the transverse trolley, then the oxygen lance 7 is lowered by the lifting trolley 13, at the moment, the hydraulic cylinder 2 drives the adjusting ring 4 to horizontally move, so that the oxygen lance 7 passes through the adjusting ring 4, the adjusting ring 4 limits the oxygen lance 7, and further, the oxygen lance hole 8 can be well aligned when the oxygen lance 7 is lowered to the oxygen lance hole 8, the whole process does not need manual operation, the safety risk and the labor intensity of personnel can be effectively reduced, the adjusting speed is high, and the adjusting precision is high.
