[0045] In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in combination with specific implementation methods. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme 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.

[0046] The operation of adding scrap steel to the converter by the overhead crane is an important part of steel production. The front and rear hooks of the overhead crane hang the front and rear lifting ears of the scrap steel bucket respectively. The overhead crane driver controls the front end of the scrap steel bucket to be higher than the rear end by raising and lowering the height of the two sets of hooks to ensure that the scrap steel in the scrap steel bucket will not fall to the ground in the air. When the overhead crane reaches the converter position, the overhead crane driver lifts the rear hook to make the rear end of the scrap steel bucket higher than the front end, and adds the scrap steel in the scrap steel bucket into the converter.

[0047] The existing overhead crane hoisting scrap steel bucket to add scrap steel to the converter is operated by the crane driver to control the front end of the scrap steel bucket to be higher than the rear end by raising and lowering the height of the front and rear sets of hooks, and then the moving trolley is aligned with the converter furnace mouth to complete the scrap steel adding operation. The existing overhead crane hoisting scrap steel bucket to add scrap steel to the converter is highly dependent on the crane driver's skill level and work responsibility. Once the crane driver makes an abnormal operation error or sudden illness, tens of tons of scrap steel may fall from a height of 20 to 30 meters, causing a major production safety accident.

[0048] In view of this, this application provides a steel bucket lifting control method, please refer to Figure 1 , Figure 1 This is a flow chart of the steel bucket lifting control method in the embodiment of the present application. The steel bucket lifting control method includes:

[0049] S101. In the process of lifting the steel bucket by the overhead crane, a first image of the steel bucket is collected.

[0050] S102: Determine the horizontality of the steel bucket according to the first image of the steel bucket.

[0051] S103. If the levelness of the steel bucket does not meet the preset levelness condition, adjust the steel bucket according to the difference between the levelness of the steel bucket and the preset levelness condition; wherein the front end of the steel bucket has a discharge port, and the preset levelness condition is that the front end of the steel bucket is higher than the rear end.

[0052] The steel bucket lifting control method provided in the embodiment of the present application collects images of the steel bucket in real time during the process of lifting the steel bucket by an overhead crane to monitor the horizontality of the steel bucket in real time. When the horizontality of the steel bucket does not meet the preset horizontality condition, the steel bucket is adjusted in real time, thereby ensuring safe operation during the process of lifting the steel bucket by the overhead crane to the converter for adding scrap steel, and preventing production safety accidents caused by overturning of the steel bucket due to misoperation, sudden illness, etc.

[0053] In some optional embodiments, such as Figure 2 As shown, the steel bucket lifting control method also includes:

[0054] S201. When the overhead crane lifts the steel bucket into position, a second image of the steel bucket is captured.

[0055] S202: Determine whether the steel bucket has moved into position according to the second image.

[0056] S203: If yes, control the steel bucket to unload.

[0057] The overhead crane does not have the function of judging whether the steel bucket has been lifted to a suitable position for unloading. It can only move to the door according to the set stroke and then stop. At this time, the second image of the steel bucket is used to determine that the steel bucket has reached a suitable position for unloading, preventing the steel bucket from unloading at the wrong position and avoiding accidents.

[0058] In some optional implementations, determining whether the steel bucket has moved into position according to the second image includes:

[0059] Determine whether a converter to be charged appears in the second image of the steel bucket;

[0060] If yes, determine whether the relative positions of the converter and the steel bucket meet the preset position conditions;

[0061] If so, make sure the steel bucket is moved into place.

[0062] The steel bucket is unloaded based on the prerequisite of image recognition to confirm that it is in place, and the lifting function is locked before the steel bucket is in place and unlocked after it is in place, to ensure safe operation during the process of the overhead crane lifting the scrap steel bucket to the converter to add scrap steel, and to prevent production safety accidents caused by the scrap steel bucket overturning due to misoperation, sudden illness, etc.

[0063] In some optional embodiments, such as Figure 3 As shown, control the unloading of the steel bucket, including:

[0064] The steel bucket is controlled to descend to a preset unloading position, which is located above the charging port of the converter and has a set height difference with the charging port of the converter.

[0065] The front end of the steel bucket is controlled to descend and approach the charging port of the converter so as to discharge the materials into the charging port of the converter through the discharging port.

[0066] In some optional implementations, determining the horizontality of the steel bucket according to the first image of the steel bucket includes:

[0067] According to the first image of the steel bucket, the height difference between the front end and the rear end of the steel bucket is determined.

[0068] Determine the levelness of the steel bucket based on the height difference between the front and rear ends of the steel bucket.

[0069] In the process of moving the steel bucket by the overhead crane, the steel bucket is lifted and moved by the overhead crane. If the levelness of the steel bucket does not meet the preset levelness condition, the steel material in the steel bucket may easily spill out from the discharge port. Based on the first image of the steel bucket, the height difference between the front and rear ends of the steel bucket is judged to accurately and quickly determine the levelness of the steel bucket.

[0070] The image acquisition unit 301 is used to acquire a first image of the steel bucket during the process of the steel bucket being lifted and moved by the overhead crane.

[0071] For example, a digital high-definition camera with a resolution of 1080p is installed 3 meters above the top of the crane driver's room. The camera faces the crane hook and is responsible for collecting real-time video images of the crane lifting the steel bucket.

[0072] The image analysis unit 302 is used to determine the levelness of the steel bucket according to the first image of the steel bucket. The image analysis unit 302 uses image processing software to analyze the levelness of the steel bucket.

[0073] The steel bucket control unit 303 is used to adjust the steel bucket according to the difference between the steel bucket and the preset level condition if the level of the steel bucket does not meet the preset level condition. The front end of the steel bucket has a discharge port, and the preset level condition is that the front end of the steel bucket is higher than the rear end.

[0074] Exemplarily, the image information of the steel bucket suspended by the overhead crane collected by the image acquisition unit 301 is identified and processed to determine the horizontality of the steel bucket lifted by the overhead crane, and is connected to the overhead crane hook lifting control interlocking module to lock the range of the lifting height difference between the two sets of hooks of the overhead crane, thereby locking the horizontality of the steel bucket in a safe state with the front high and the back low.

[0075] The overhead crane does not have the function of judging whether the steel bucket has been lifted to a suitable position for unloading. It can only move to the door according to the set stroke and then stop. At this time, the second image of the steel bucket is used to determine that the steel bucket has reached a suitable position for unloading, preventing the steel bucket from unloading at the wrong position and avoiding accidents.

[0076] In some optional implementations, the image acquisition unit 301 is further used to acquire a second image of the steel bucket when the overhead crane lifts the steel bucket into place;

[0077] The image analysis unit 302 is further used to determine whether the steel bucket has moved into position according to the second image;

[0078] The steel bucket control unit 303 is also used to control the steel bucket to unload if yes.

[0079] There is a cab on the overhead crane for the operator to control the operation of the overhead crane. The cab is on the side and rear of the steel bucket, and the camera is above the cab. The image analysis unit 302 of the overhead crane positioning system determines that the overhead crane has reached the position for adding scrap steel to the converter. When the overhead crane reaches the position for adding scrap steel to the converter, the lifting control interlocking device of the overhead crane hook releases the lifting locking function, and the overhead crane can normally lift the hook to complete the operation of adding scrap steel to the converter.

[0080] The system can ensure safe operation during the process of overhead crane lifting the steel bucket to the converter to add scrap steel, and prevent production safety accidents caused by overturning of the steel bucket due to personnel misoperation, sudden illness, etc.

[0081] In some optional embodiments, such as Figure 4 As shown, the image analysis unit 302 includes:

[0082] The first judging unit 401 is used to judge whether a converter to be charged appears in the second image of the steel bucket.

[0083] The second judgment unit 402 is used to judge whether the relative position of the converter and the steel bucket meets the preset position condition; if so, it is determined that the steel bucket is moved into position.

[0084] In a third aspect, a crane system is provided, such as Figure 5 As shown, the overhead crane system 500 includes: an overhead crane 501, a steel bucket 502, an image acquisition mechanism 503, a lifting mechanism 504, and a control mechanism 505;

[0085] The overhead travelling crane 501 is arranged on a preset track;

[0086] The steel bucket 502 is located below the overhead crane 501 and is connected to the overhead crane 501 through a lifting mechanism 504;

[0087] The image acquisition mechanism 503 is disposed on one side of the steel bucket 502, and is used to acquire a first image of the steel bucket 502 during the process of the overhead crane 501 lifting and moving the steel bucket 502;

[0088] The control mechanism 505 is electrically connected to the image acquisition mechanism 503 and the lifting mechanism 504, respectively, and is used for receiving the first image of the steel bucket 502 sent by the image acquisition mechanism 503, and determining the horizontality of the steel bucket 502 according to the first image of the steel bucket 502; if the horizontality of the steel bucket 502 does not meet the preset horizontality condition, then according to the difference between the horizontality of the steel bucket 502 and the preset horizontality condition, the lifting mechanism 504 is controlled to adjust the steel bucket 502; wherein, the front end of the steel bucket 502 has a discharge port, and the preset horizontality condition is that the front end of the steel bucket 502 is higher than the rear end.

[0089] In some optional embodiments, the lifting mechanism 504 includes a first lifting component and a second lifting component, one end of the first lifting component is connected to the overhead crane 501, and the other end is connected to the front end of the steel bucket 502; one end of the second lifting component is connected to the overhead crane 501, and the other end is connected to the rear end of the steel bucket 502; the controller is electrically connected to the first lifting component and the second lifting component, and is used to control the first lifting component to drive the front end of the steel bucket 502 to rise or fall, and is used to control the second lifting component to drive the rear end of the steel bucket 502 to rise or fall.

[0090] In some optional embodiments, the first lifting assembly includes a first motor, a first cable, and a first hook. The base of the first motor is fixedly connected to the overhead travelling crane 501, one end of the first cable is connected to the output shaft of the first motor, and the other end is connected to the first hook.

[0092] Exemplarily, a positioning detection device for the overhead crane 501 is installed along the track of the overhead crane 501 platform, which is responsible for collecting the running position of the overhead crane 501 for lifting scrap steel in real time and determining whether the overhead crane 501 has reached the workstation for adding scrap steel to the converter. According to the position information of the overhead crane 501 transmitted by the positioning module of the overhead crane 501, when the overhead crane 501 has not reached the workstation for adding scrap steel to the converter, the lifting height of the two sets of hooks of the overhead crane 501 is always locked in a state of high front and low back; when the overhead crane 501 reaches the workstation for adding scrap steel to the converter, the lifting control interlocking device of the hook of the overhead crane 501 releases the limiting locking function of the lifting height, and the driver of the overhead crane 501 can freely adjust the height difference between the two sets of hooks to complete the operation of adding scrap steel to the converter.

[0093] In summary, the steel bucket lifting control device 300 provided in the embodiment of the present application realizes accurate judgment of the horizontality of the steel bucket 502 lifted by the crane 501. The positioning technology of the crane 501 is adopted to realize the real-time acquisition of the running position of the crane 501. By connecting with the on-site crane 501 hook control system, the automatic switching of the locking and unlocking functions of the two sets of hooks of the crane 501 is realized. The risk of manual operation during the lifting process of the crane 501 is reduced, and the inherent safety level of the steelmaking production process is improved.
