The accompanying drawings are only for the purpose of illustrating the preferred embodiments and are not to be considered as limiting the present invention. Moreover, the same reference symbols are used throughout the accompanying drawings to represent the same components. In the accompanying drawings:

[0030] Figure 2 The present invention provides a flowchart of an oxygen lance falling prevention method. DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the implementation mode of the present application will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0032] Figure 1 is a structural block diagram of an oxygen lance anti-falling system provided by an embodiment of the present invention, such as Figure 1 As shown, the system 100 includes an oxygen gun 1, a detection device 2, a braking device 3 and a controller 4, and the controller 4 is connected to the detection device 2 and the braking device 3 respectively.

[0033] The detection device 2 is used to detect the descending parameters of the oxygen lance 1 , and the braking device 3 is used to provide braking force for the oxygen lance 1 .

[0034] Controller 4 is used for:

[0035] The descent parameter of the oxygen lance 1 detected by the detection device 2 is obtained; if the descent parameter meets the preset condition, the braking device 3 is controlled to provide a braking force for the oxygen lance 1 to prevent the oxygen lance 1 from continuing to fall.

[0036] In this embodiment, when the oxygen lance 1 is working, the oxygen lance 1 will descend along the slideway into the converter, and when it reaches the oxygen opening point in the converter, it will spray oxygen into the converter. Under normal circumstances, the descent speed of the oxygen lance 1 is controllable, that is, it is in a normal descent state, but when an abnormal situation occurs, the oxygen lance 1 may be in an abnormal descent state.

[0037] Therefore, in this embodiment, the detection device 2 detects the descent parameters of the oxygen lance 1 in real time, and the descent parameters are used to reflect whether the descent state of the oxygen lance 1 is abnormal. If the controller 4 analyzes that the descent parameters meet the preset conditions, it means that the descent state of the oxygen lance 1 is abnormal and there is a risk of falling; if the controller 4 analyzes that the descent parameters do not meet the preset conditions, it means that the descent state of the oxygen lance 1 is normal and there is no risk of falling. If the oxygen lance 1 has a risk of falling, the controller 4 controls the brake device 3 to provide a braking force for the oxygen lance 1. The direction of the braking force is opposite to the descent direction of the oxygen lance 1. The braking force offsets the force that causes the abnormal descent of the oxygen lance 1, so that the oxygen lance 1 can stop falling. The brake device 3 prevents the oxygen lance 1 from falling, so that the oxygen lance 1 will not collide with other devices, which can reduce the impact on the oxygen lance 1 and related equipment when it falls, reduce the degree of damage to the oxygen lance 1 and related equipment, and extend the life of the equipment. The system can prevent the oxygen lance 1 from falling in advance, brake the oxygen lance 1 when there is a risk of falling, realize the automation and intelligence of the system, improve the response speed, and reduce human intervention and maintenance costs.

[0038] Optionally, the detection device 2 includes at least one of a camera and a sensor.

[0039] In this embodiment, the descent parameters of the oxygen lance 1 may be detected by using a camera alone, or by using a sensor alone, or by using a camera and a sensor simultaneously, so that the detection result is more accurate.

[0040] Optionally, the camera includes a camera head and an image processing module; the camera head is used to capture an image of the oxygen lance 1; and the image processing module is used to determine the descent parameters of the oxygen lance 1 according to the image.

[0041] In this embodiment, the image of the oxygen lance 1 can be collected in real time by a camera, and the image processing module can identify and analyze the descending state of the oxygen lance 1 in the image, thereby determining the descending parameters of the oxygen lance 1. For example, by comparing the oxygen lance positions in the image at the current moment and the image at the next moment, the descending speed and the descending acceleration of the oxygen lance can be calculated.

[0042] In this embodiment, the controller 4 is also used for:

[0043] Whether the tilt angle of the oxygen lance 1 is abnormal is identified based on the image; if the tilt angle is abnormal, an alarm is issued, so that the user can pay more attention to the state of the oxygen lance 1, so that countermeasures can be prepared in advance when the oxygen lance 1 is at risk of falling.

[0044] In this embodiment, the descending parameters of the oxygen lance 1 may also be directly collected by a sensor.

[0045] Optionally, the sensor includes at least one of a velocity sensor and an acceleration sensor.

[0046] In this embodiment, the descent speed of the oxygen lance 1 can be collected by a speed sensor, and the descent acceleration of the oxygen lance 1 can be collected by an acceleration sensor. When the descent state of the oxygen lance 1 is normal, the descent speed and the descent acceleration are both within the normal range, so the descent speed and the descent acceleration can be used as descent parameters.

[0047] In this embodiment, if the descent parameter only includes the descent speed, the controller 4 is further configured to:

[0048] If the descending speed is greater than a preset speed threshold, the braking device 3 is controlled to provide a braking force for the oxygen lance 1 .

[0049] In this embodiment, if the descent parameter only includes the descent acceleration, the controller 4 is further configured to:

[0050] If the descending acceleration is greater than a preset acceleration threshold, the braking device 3 is controlled to provide a braking force for the oxygen lance 1 .

[0051] Optionally, the descent parameters include descent speed and descent acceleration, and the controller 4 is further used for:

[0052] If the descending speed is greater than a preset speed threshold and the descending acceleration is greater than a preset acceleration threshold, the braking device 3 is controlled to provide a braking force for the oxygen lance 1 .

[0053] In this embodiment, for the sake of safety, when the descending speed is greater than the preset speed threshold and the descending acceleration is greater than the preset acceleration threshold, the brake device 3 is controlled to provide braking force for the oxygen lance 1 to prevent misjudgment and affect the normal operation of the converter.

[0054] In this embodiment, the controller 4 is also used for:

[0055] According to the descending parameter, the actual braking force of the braking device 3 is determined, and the braking force provided by the braking device 3 to the oxygen lance 1 is controlled to be the actual braking force.

[0056] It can be understood that the brake device 3 can provide braking forces of different sizes. If the descent parameter indicates that the oxygen lance 1 is abnormally descending very quickly, the brake device 3 can be controlled to provide a larger braking force to stop the oxygen lance 1 from falling more quickly; if the descent parameter indicates that the oxygen lance 1 is abnormally descending slightly faster, the brake device 3 can be controlled to provide a smaller braking force to stop the oxygen lance 1 from falling more smoothly.

[0057] In this embodiment, the controller 4 is also used for:

[0058] The actual braking force of the braking device 3 is determined according to the descending parameter and the load of the oxygen lance 1 .

[0059] When determining the actual braking force of the brake device 3, the load of the oxygen gun 1 must also be considered, because the greater the load, the greater the gravity will be, and the more serious the fall will be. Therefore, determining the actual braking force based on the descent parameters and the load can make the fall protection more stable.

[0060] Optionally, the braking device 3 includes at least one of an electromagnetic brake and a hydraulic buffer.

[0061] Among them, the electromagnetic brake is a mechanical part that uses electromagnetic effect to achieve braking, commonly known as brakes and gates. Its working principle is mainly based on electromagnetic induction and eddy current effect. When the excitation coil of the electromagnetic brake is connected to the rated voltage, an electromagnetic force will be generated. This electromagnetic force will attract the armature, causing the armature and the brake disc to disengage (release). At this time, the gear with the brake disc can enable the oxygen gun 1 to operate normally. When the excitation coil is powered off, the electromagnetic force disappears, the brake disc and the armature contact, causing the gear to gradually slow down, and the oxygen gun also slows down, and finally stops falling, thereby avoiding sudden mechanical shock. Electromagnetic braking can respond within milliseconds, ensuring timely intervention at the early stage of the fall and reducing the impact on the equipment.

[0062] The working principle of the hydraulic buffer is mainly to pressurize the hydraulic oil through the oil pump, and then convert the oil pressure into braking force. The braking force generated by the compression or flow of the liquid in the hydraulic buffer is used to absorb and disperse the downward impact force of the oxygen lance 1. When the oxygen lance 1 falls, the hydraulic buffer will push the buffer pad upward, and the buffer pad will contact the slide of the oxygen lance, generating an upward thrust on the oxygen lance, gradually increasing the thrust, so that the oxygen lance can be decelerated steadily until it stops falling. The thrust of the hydraulic buffer can be precisely controlled by adjusting the flow and pressure of the hydraulic oil, and the oxygen lance can be decelerated step by step by controlling the size of the thrust.

[0063] Among them, the cushion can use flexible materials to effectively absorb the impact force of the oxygen gun and disperse the energy through material deformation. This type of material has a high elastic modulus and excellent fatigue resistance, and can maintain its function for a long time without attenuation. The cushion can also use polymer cushioning materials, which can be used to protect the oxygen gun (such as polyurethane or rubber). When impacted, it can be quickly compressed and restored to its original state, effectively absorbing the impact force and reducing the transmission of the impact force.

[0064] In this embodiment, when the oxygen lance 1 is at risk of falling, the oxygen lance 1 can be braked by one of the electromagnetic brake and the hydraulic buffer, or the electromagnetic brake and the hydraulic buffer can be used together to brake the oxygen lance 1, so that the braking effect is better, the oxygen lance 1 can stop falling faster, and the damage can be minimized.

[0065] The system achieves lossless protection against the fall of the oxygen gun 1 through a multi-level protection design. It can further provide secondary buffering of hydraulic buffers and flexible materials after the primary buffering of the electromagnetic brake, decomposing the one-time impact into multiple stages, further reducing the damage to the equipment caused by a single impact, and ensuring that the oxygen gun 1 finally stops smoothly after multiple buffering. When the electromagnetic brake fails, the hydraulic buffer can work independently to ensure the reliability and safety of the system's anti-falling.

[0066] Based on the same inventive concept, an embodiment of the present invention also provides an oxygen lance falling prevention method. Figure 2 is a flow chart of an oxygen lance falling prevention method provided by an embodiment of the present invention, such as Figure 2 As shown, the method includes step S210 and step S220.

[0068] Step S220: If the descending parameter meets the preset condition, the braking device is controlled to provide braking force for the oxygen lance to prevent the oxygen lance from continuing to fall.

[0069] Optionally, the descent parameters include descent speed and descent acceleration, and step S220 includes:

[0070] If the descending speed is greater than a preset speed threshold and the descending acceleration is greater than a preset acceleration threshold, the braking device is controlled to provide a braking force for the oxygen lance.

[0071] Optionally, step S220 further includes:

[0072] According to the descending parameter, the actual braking force of the braking device is determined, and the braking force provided by the braking device to the oxygen gun is controlled to be the actual braking force.
