DETAILED DESCRIPTION

[0048] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0049] like Figure 1 and Figure 2As shown, according to the first aspect of an embodiment of the present disclosure, a bucket sampling device 100 is proposed, comprising: a bracket assembly 110, used to be set on a working platform 400', and the working platform 400' is located on one side of the ladle 100'; a support rod 120, hinged to the bracket assembly 110; a bucket lifting assembly 130, arranged on the support rod 120; a first driving assembly 140, arranged on the bracket assembly 110, used to drive the support rod 120 to rotate between a first angular position and a second angular position, when the support rod 120 is located at the first angular position, the extension direction of the support rod 120 intersects with the opening 101' of the ladle 100', and when the support rod 120 is located at the second angular position, the extension direction of the support rod 120 intersects with the working platform 400'; a second driving assembly 150, arranged on the bracket assembly 110, used to drive the bucket lifting assembly 130 to move along the extension direction of the support rod 120.

[0050] The bucket sampling device 100 provided in the embodiment of the present disclosure includes a support assembly 110, a support rod 120, a bucket assembly 130, a first drive assembly 140 and a second drive assembly 150; wherein the support rod 120, the first drive assembly 140 and the second drive assembly 150 are all arranged on the support assembly 110, and the support rod 120 is hinged to the support assembly 110 and can rotate relative to the support assembly 110, the bucket assembly 130 is arranged on the support rod 120 and can move along the extension direction of the support rod 120, and the first drive assembly 140 and the second drive assembly 150 are respectively used to drive the support rod 120 and the bucket assembly 130 to move; in actual application, the support assembly 110 can be arranged on the working platform 400' so that the bucket sampling device 100 is adjacent to the ladle 100 on one side of the working platform 400' ', the first drive assembly 140 can drive the support rod 120 to rotate between the first angular position and the second angular position, so that the extension direction of the support rod 120 is switched between the posture of intersecting the opening 101' of the ladle 100' and intersecting the working platform 400'; when the support rod 120 is located at the first angular position, the bucket lifting assembly 130 can be driven by the second drive assembly 150, so as to approach or move away from the opening 101' of the ladle 100', so that the bucket lifting assembly 130 can enter the interior of the ladle 100' and collect molten steel samples, or take the molten steel samples out of the ladle 100'; when the support rod 120 is located at the second angular position, the bucket lifting assembly 130 can be near the working platform 400', so as to facilitate the operator to collect the molten steel samples in the bucket lifting assembly 130 and perform maintenance and replacement of the bucket lifting assembly 130. Based on this, the bucket sampling device 100 provided in the embodiment of the present disclosure can reduce the workload of operators during sampling, reduce the risks of operators during the sampling process, improve the safety and execution efficiency of sampling operations, and help reduce production costs. The movement of the bucket lifting assembly 130 can be completed under the drive of the second drive assembly 150, which is conducive to more precise control of the movement of the bucket lifting assembly 130, thereby ensuring the sampling quality and improving the accuracy of molten steel analysis.

[0051] It can be understood that the aforementioned first angle position and second angle position refer to the angular position of the support rod 120 relative to the bracket assembly 110. In actual applications, the specific angle values ​​corresponding to the first angle position and the second angle position can be set in combination with actual needs, so that when the support rod 120 is in the first angle position, its extension direction intersects with the opening 101' of the ladle 100', and when it is in the second angle position, its extension direction intersects with the working platform 400'. No excessive restrictions are made here.

[0052] It is understandable that if Figure 1As shown, the aforementioned working platform 400 ′ may be a working platform 400 ′ adjacent to the vacuum chamber 200 ′ in a production site.

[0053] Taking the aforementioned working platform 400' as an example, when it is a working platform 400' adjacent to the vacuum chamber 200', in actual application, the support assembly 110 can be set on the top wall of the working platform 400'. After the ladle 100' enters the station, it can be opened to the processing position and lifted to the height for processing molten steel, so that the immersion tube 300' of the vacuum chamber 200' is immersed in the molten steel to a certain depth, thereby starting to smelt the molten steel. During the smelting process, if bucket sampling is required, the first drive assembly 140 can be controlled to operate so that the support rod 120 is located at the aforementioned first angle position, so that the bucket lifting assembly 130 can move closer to or farther away from the opening 101' of the ladle 100' during the movement along the extension direction of the support rod 120; accordingly, the second drive assembly 150 can be controlled to operate so that the bucket lifting assembly 130 extends into the ladle 100' through the opening 101' of the ladle 100' and collects molten steel samples at a certain depth below the top slag 103'; after a certain period of sample collection, the bucket lifting assembly 130 can be driven to withdraw from the ladle 100' by the second drive assembly 150, and the first drive assembly 140 can be used to drive the support rod 120 to rotate from the first angle position to the second angle position, so that the bucket lifting assembly 130 is located above the working platform 400', which is convenient for the operator to collect samples.

[0054] like Figure 1 As shown, in some examples, the first driving assembly 140 includes: a telescopic cylinder, which is disposed on the support assembly 110 , and the output end of the telescopic cylinder is hinged to the support rod 120 .

[0055] In this technical solution, the first drive assembly 140 may include a telescopic cylinder arranged on the bracket assembly 110, and the output end of the telescopic cylinder is hinged to the support rod 120, so that the telescopic cylinder, the support rod 120 and the bracket assembly 110 can form a connecting rod mechanism. Accordingly, the support rod 120 can be rotated between the first angle position and the second angle position by adjusting the length of the telescopic cylinder. Therefore, on the one hand, the first drive assembly 140 can use the telescopic cylinder to provide power for the rotation of the support rod 120, thereby improving the ease of use of the bucket sampling device 100; on the other hand, it can also reduce the structural complexity of the first drive assembly 140 and the motion mechanism of the bucket sampling device 100, thereby reducing the manufacturing cost and repair and maintenance cost of the bucket sampling device 100.

[0056] Exemplarily, the aforementioned telescopic cylinder may be a telescopic air cylinder.

[0057] like Figure 1 and Figure 2As shown, in some examples, the second driving assembly 150 includes: a reduction motor 151, which is arranged on the bracket assembly 110; a first sprocket 152, which is rotatably arranged on the support rod 120, and the output shaft of the reduction motor 151 is connected to the first sprocket 152; a second sprocket 153, which is rotatably arranged on the support rod 120, and the second sprocket 153 is spaced apart from the first sprocket 152 along the extension direction of the support rod 120; a chain 154, which is connected between the first sprocket 152 and the second sprocket 153, and the bucket lifting assembly 130 is arranged on the chain 154.

[0058] In this technical solution, the second drive assembly 150 may include the aforementioned reduction motor 151, the first sprocket 152, the second sprocket 153 and the chain 154. Based on the aforementioned arrangement, the second drive assembly 150 may utilize the reduction motor 151 to drive the bucket lifting assembly 130 to move by chain transmission, which is beneficial to improving the movement stability of the bucket lifting assembly 130 and facilitating the control of the movement speed of the bucket lifting assembly 130, thereby helping to improve the sampling quality and provide a guarantee for the accuracy of molten steel analysis.

[0059] It can be understood that the aforementioned reduction motor 151 may include a motor body and a reducer connected to each other, wherein the output shaft of the reducer is connected to the first sprocket 152 .

[0060] It is understandable that, based on the above configuration, part of the chain 154 may extend along the extension direction of the support rod 120 , and the bucket lifting assembly 130 may be disposed on the part of the chain 154 extending along the extension direction of the support rod 120 .

[0061] It can be understood that in actual applications, while the first drive assembly 140 includes the aforementioned telescopic cylinder, the second drive assembly 150 can be set to include the aforementioned reduction motor 151, the first sprocket 152, the second sprocket 153 and the chain 154, so as to further reduce the movement mechanism of the bucket sampling device 100, improve the structural compactness of the bucket sampling device 100, and reduce the manufacturing cost and repair and maintenance cost of the bucket sampling device 100.

[0062] like Figure 1 As shown, in some examples, the bucket lifting assembly 130 includes: a fixing portion 131 connected to the second driving assembly 150 ; a connecting rod 132 disposed on the fixing portion 131 ; and a bucket body 133 disposed on the connecting rod 132 .

[0063] In this technical solution, the bucket lifting assembly 130 may include the aforementioned fixing portion 131, a connecting rod 132 and a barrel body 133, wherein the barrel body 133 may be used to accommodate a molten steel sample. Based on the aforementioned arrangement, the bucket lifting assembly 130 may utilize the fixing portion 131 to connect the second driving assembly 150 and structurally fix and support the connecting rod 132 and the barrel body 133. When the second driving assembly 150 is running, the fixing portion 131 may generate a displacement along the extension direction of the support rod 120, and drive the connecting rod 132 and the barrel body 133 to move synchronously, so that the barrel body 133 can extend into or out of the ladle 100'. The connecting rod 132 may extend the distance between the barrel body 133 and the fixing portion 131, which is beneficial to shortening the travel range requirement of the fixing portion 131.

[0064] Exemplarily, the fixing portion 131 and the connecting rod 132 may be in a detachable connection relationship.

[0065] like Figure 1 As shown, in some feasible examples, the bucket sampling device 100 also includes a control component 160, which is electrically connected to the first drive component 140 and the second drive component 150, and is used to control the operation of the first drive component 140 and the second drive component 150; illustratively, the control component 160 may include a start button, a processing module and a storage module, wherein a control program may be set in the storage module, and the processing module is used to execute the aforementioned control program. When the start button is triggered, the start button may send instruction information to the processing module so that the processing module executes the aforementioned control program, thereby controlling the operation of the first drive component 140 and the second drive component 150. It can be understood that the aforementioned control program can be set in combination with actual needs, and no excessive restrictions are made here.

[0066] like Figure 3 As shown, according to the second aspect of the embodiment of the present disclosure, a control method of a bucket sampling device is proposed, which is used for the bucket sampling device 100 proposed in any one of the first aspects above, and the control method includes:

[0067] Step S301: In response to the sampling instruction, the first driving assembly 140 is controlled to operate until the support rod 120 is located at the first angle position; it can be understood that when the bucket sampling device 100 receives the sampling instruction, the first driving assembly 140 can be controlled to operate, and accordingly, the first driving assembly 140 can drive the support rod 120 to rotate relative to the bracket assembly 110. When the support rod 120 rotates to the first angle position, the first driving assembly 140 can be controlled to close so that the support rod 120 remains at the first angle position, so that the bucket lifting assembly 130 is convenient to move closer to or farther from the opening 101' of the ladle 100' in the process of moving along the extension direction of the support rod 120, so that the bucket lifting assembly 130 can collect the molten steel sample. The aforementioned sampling instruction can be issued by the operator or automatically generated according to the process of molten steel smelting. The specific generation method of the sampling instruction is not limited here.

[0068] Step S302: When the support rod 120 rotates to the first angular position, the second drive assembly 150 is controlled to operate until the bucket lifting assembly 130 is inserted into the ladle 100' at a preset depth position; it can be understood that when the support rod 120 rotates to the first angular position, the extension direction of the support rod 120 intersects with the opening 101' of the ladle 100', which is suitable for the bucket lifting assembly 130 to approach or move away from the opening 101' of the ladle 100' by moving along the extension direction of the support rod 120, so that the second drive assembly 150 can be controlled to operate, so that the second drive assembly 150 drives the bucket lifting assembly 130 to move in the direction of inserting into the ladle 100'. When the bucket lifting assembly 130 is inserted into the ladle 100' at the preset depth position, the second drive assembly 150 can be controlled to close, so that the bucket lifting assembly 130 remains at the aforementioned preset depth position and the molten steel sample is collected. The preset depth position is lower than the molten steel level position 102' in the ladle 100', so as to ensure that the bucket assembly 130 is immersed in the molten steel.

[0069] Step S303: When the sampling time reaches the preset time, the second drive assembly 150 is controlled to operate until the bucket lifting assembly 130 exits the ladle 100'. The sampling time is the duration that the bucket lifting assembly 130 is located at the preset depth position. It can be understood that by controlling the bucket lifting assembly 130 to maintain the preset depth position for the preset time, the molten steel in the ladle 100' can be filled with relatively sufficient time for the bucket lifting assembly 130 to lift the bucket. Accordingly, when the sampling time reaches the preset time, the second drive assembly 150 can be controlled to operate, so that the second drive assembly 150 drives the bucket lifting assembly 130 to move in the direction of exiting the ladle 100'. When the bucket lifting assembly 130 exits the ladle 100', the second drive assembly 150 can be controlled to be closed, so as to stabilize the bucket lifting assembly 130 and the molten steel sample collected therein, and reduce the risk of sample overflow. The aforementioned preset duration can be set specifically based on actual conditions. For example, the aforementioned preset duration can be greater than or equal to 20s, for example, it can be 30s, 40s, 50s, etc. The specific value of the aforementioned preset duration is not limited here.

[0070] Step S304: When the bucket lifting assembly 130 exits the ladle 100', the first driving assembly 140 is controlled to operate until the support rod 120 is located at the second angle position. It is understandable that when the bucket lifting assembly 130 exits the ladle 100', it can be convenient to follow the support rod 120 to rotate to return to the working platform 400'. Accordingly, the first driving assembly 140 can be controlled to operate until the support rod 120 is located at the second angle position, so that the bucket lifting assembly 130 is located in the vicinity of the working platform 400', which is convenient for the operator to collect the sample in the bucket lifting assembly 130, and it is also convenient for the operator to maintain and replace the bucket lifting assembly 130 to prepare for the next sampling operation.

[0071] In summary, the control method of the bucket sampling device provided in the embodiment of the present disclosure can be used to control the bucket sampling device 100 as proposed in any one of the first aspects above, thereby improving the ease of use and the level of automation of the bucket sampling device 100, which is beneficial to improving the operating stability and sampling quality of the bucket sampling device 100, can reduce the workload of operators during sampling, reduce the risks of operators during the sampling process, improve the safety and execution efficiency of sampling operations, and help reduce production costs.

[0072] In some examples, the aforementioned step S302 includes:

[0073] When the support rod 120 rotates to the first angle position, the second driving assembly 150 is controlled to operate so that the second driving assembly 150 drives the bucket lifting assembly 130 to move at a first preset speed;

[0074] When the bucket lifting assembly 130 is located at a preset depth, the second driving assembly 150 is controlled to be closed.

[0075] Specifically, in the process of controlling the operation of the second driving assembly 150 until the bucket lifting assembly 130 is inserted into the preset depth position in the ladle 100', the moving speed of the bucket lifting assembly 130 can be constrained, so that the bucket lifting assembly 130 moves at a first preset moving speed, thereby improving the movement stability of the bucket lifting assembly 130 in the process of extending into the ladle 100', which is beneficial to improving the sampling uniformity of the bucket lifting assembly 130, reducing the risk of a large amount of top slag 103' being mixed into the molten steel sample, improving the sampling quality of the bucket lifting sampling device 100, and providing a guarantee for the accuracy of molten steel analysis.

[0076] Exemplarily, the first preset speed may be greater than or equal to 150 mm / s and less than or equal to 250 mm / s. For example, the first preset speed may be 180 mm / s, 200 mm / s, or 230 mm / s, etc.

[0077] In some examples, the aforementioned step S303 includes:

[0078] When the sampling time reaches the preset time, the second driving assembly 150 is controlled to operate so that the second driving assembly 150 drives the bucket lifting assembly 130 to move at a second preset speed;

[0079] When the bucket lifting assembly 130 exits the ladle 100 ′, the second driving assembly 150 is controlled to be closed.

[0080] Specifically, when controlling the operation of the second driving assembly 150 until the bucket lifting assembly 130 exits the ladle 100', the moving speed of the bucket lifting assembly 130 can be constrained so that the bucket lifting assembly 130 moves at a second preset moving speed, thereby improving the movement stability of the bucket lifting assembly 130 during the process of exiting the ladle 100', which is beneficial to improving the sampling uniformity of the bucket lifting assembly 130, reducing the risk of a large amount of top slag 103' being mixed into the molten steel sample, improving the sampling quality of the bucket lifting sampling device 100, and providing a guarantee for the accuracy of molten steel analysis.

[0081] For example, the second preset speed may be greater than or equal to 150 mm / s and less than or equal to 250 mm / s. For example, the first preset speed may be 180 mm / s, 200 mm / s or 230 mm / s, etc.

[0082] It can be understood that the aforementioned first preset speed and the aforementioned second preset speed can be the same and both are greater than or equal to 150 mm / s and less than or equal to 250 mm / s, for example, both are 180 mm / s, 200 mm / s or 230 mm / s.

[0083] In some examples, the difference between the molten steel level position 102 ′ in the ladle 100 ′ and the preset depth position is greater than or equal to 200 mm and less than or equal to 400 mm.

[0084] Specifically, the preset depth position can be 200 to 400 mm lower than the molten steel level position 102' in the ladle 100'. Therefore, by controlling the bucket lifting assembly 130 to collect samples at the preset depth position, the sampling uniformity of the bucket lifting assembly 130 can be ensured, the sampling quality of the bucket lifting sampling device 100 can be improved, and the accuracy of molten steel analysis can be guaranteed.

[0085] For example, the difference between the molten steel level position 102' in the ladle 100' and the preset depth position may be 250 mm, 300 mm, 350 mm, or the like.

[0086] In some feasible examples, the difference between the molten steel level position 102 ′ in the ladle 100 ′ and the preset depth position is positively correlated with the thickness of the top slag 103 ′ in the ladle 100 ′.

[0087] Specifically, by setting the difference between the molten steel surface position 102' in the ladle 100' and the preset depth position, which is positively correlated with the thickness of the top slag 103' in the ladle 100', when the thickness of the top slag 103' in the ladle 100' is relatively thick, the bucket lifting assembly 130 can be used to collect samples in a deeper area of ​​the molten steel, which is beneficial to reducing the risk of a large amount of impurities being mixed into the sample and ensuring the sampling quality. Correspondingly, when the thickness of the top slag 103' in the ladle 100' is relatively thin, the bucket lifting assembly 130 can be used to collect samples in a shallower area of ​​the molten steel, which is beneficial to saving the time spent by the bucket lifting assembly 130 in entering or exiting the ladle 100' and improving the sampling efficiency.
