TECHNICAL FIELD

[0001] The present application relates to the technical field of molten iron transportation control of metallurgical railway, in particular to a molten iron transportation control method of self-propelled torpedo ladle. BACKGROUND

[0002] At present, the basic mode of molten iron transportation management of metallurgical enterprises is that locomotives pull torpedo ladles to run, the transportation dispatcher receives the information of full torpedo ladles of molten iron informed by the ironmaking personnel through command telephone, combines the real-time position of the locomotive on site, the information of the locomotive executing the operation instruction, the production process of the steelmaking, and the position information of the heavy torpedo ladle in the steelmaking area, and selects the most reasonable locomotive and the best destination through the picture dragging mode of the iron area production management system to issue the locomotive operation instruction.

[0003] After the locomotive on-board data transmission terminal receives the locomotive operation instruction, the locomotive driver confirms it on the locomotive on-board data transmission terminal, then operates the locomotive to perform the coupling with the torpedo ladle, sends the torpedo ladle to the destination required by the locomotive operation instruction through the self-selected route, and confirms the completion of the operation instruction on the locomotive on-board data transmission terminal after the operation task is completed.

[0004] The conventional way of molten iron transportation is that the locomotive driver operates the locomotive to complete the coupling with the torpedo ladle, and then sends the torpedo ladle to the destination specified by the locomotive operation instruction in the manner of pulling or pushing the torpedo ladle.

[0005] Therefore, the prior art has the following problems:

[0006] 1. The operation of the torpedo ladle needs the traction or pushing of the locomotive, and the torpedo ladle cannot run by itself.

[0007] 2. The locomotive operation instruction needs to be issued manually, and cannot be automatically issued. SUMMARY

[0008] In order to solve the above problems of the prior art, the present application provides a molten iron transportation control method of self-propelled torpedo ladle, which is based on the self-propelled torpedo ladle, combines the production information of steelmaking and blast furnace, and realizes the autonomous operation of the torpedo ladle through the automatic control of the production operation control module, thereby overturning the traditional molten iron transportation mode of locomotive pulling the torpedo ladle.

[0012] S3. When the self-propelled torpedo tank truck production operation control module receives the torpedo tank truck full information issued by the blast furnace production information system, according to the idle information of the steelmaking area parking position judged by the self-propelled torpedo tank truck production operation control module, an idle parking position is selected, the position is set as the end point of the full torpedo tank truck, the operation instruction is issued to control the self-propelled torpedo tank truck to run to the operation instruction end point according to the operation instruction end point, and the in-place information is fed back to complete the operation instruction;

[0013] S4. When the self-propelled torpedo tank truck production operation control module does not receive the self-propelled torpedo tank truck full information, and does not receive the heavy tank demand information of the tank station, according to the position information of the self-propelled torpedo tank truck in the steelmaking area parking position, the heavy torpedo tank truck in the area is controlled to orderly move forward to the idle parking position in front of the tank station along the railway line to the direction of the blast furnace, so as to give way to the running route of the heavy torpedo tank truck coming from the direction of the blast furnace.

[0014] In step S2, the corresponding control includes:

[0015] When the heavy tank demand information only contains the demand work station and does not contain the torpedo tank truck tank number, the self-propelled torpedo tank truck production operation control module sends the operation instruction to the self-propelled torpedo tank truck closest to the tank station according to the work station of the heavy tank demand information issued by the steelmaking production information system, combined with the position information of the self-propelled torpedo tank truck in the steelmaking area, controls the self-propelled torpedo tank truck to run to the specified work station, and feeds back the in-place information.

[0016] In step S2, the corresponding control further includes:

[0017] When the heavy tank demand information does not contain the demand work station and contains the torpedo tank truck tank number, the self-propelled torpedo tank truck production operation control module sends the operation instruction to the specified self-propelled torpedo tank truck according to the heavy tank demand information issued by the steelmaking production information system, combined with the work station idle information in the steelmaking tank station, controls the self-propelled torpedo tank truck to run to any idle work station, and feeds back the in-place information.

[0018] In step S2, the corresponding control further includes:

[0019] When the heavy tank demand information contains the demand work site and the torpedo tank truck tank number, the self-propelled torpedo tank truck production operation control module sends operation instructions to the specified self-propelled torpedo tank truck according to the demand work site and the torpedo tank truck tank number information issued by the steel production information system, controls the self-propelled torpedo tank truck to run to the specified work site autonomously, and feeds back the arrival information.

[0020] In step S2, the corresponding control further includes:

[0037] A molten iron transportation control method for a self-propelled torpedo ladle car of the present application is described further below. Figures 1-2 As shown in the figure, the self-propelled torpedo ladle car can adopt the following form, using green energy technology super capacitor as the power system to provide sufficient energy guarantee for the torpedo ladle car, installing permanent magnet synchronous motor and reduction box in the form of holding shaft on the running part of the self-propelled torpedo ladle car to provide traction for the torpedo ladle car, and under the support of the control system, braking system and other hardware and software, the torpedo ladle car can realize autonomous operation to overturn the traditional locomotive traction torpedo ladle car molten iron transportation mode.

[0038] The molten iron transportation control method of the self-propelled torpedo ladle car of the present application, on the basis of the use of the self-propelled torpedo ladle car, establishes a self-propelled torpedo ladle car production operation control module in combination with steelmaking, blast furnace and other production information, one of the functions is to automatically generate the operation instruction of the heavy self-propelled torpedo ladle car, which is as follows:

[0039] Scenario 1: No information is received that the self-propelled torpedo ladle car is full, and information is received that the heavy ladle is required at the ladle dumping station.

[0040] ​​​When the self-propelled torpedo ladle car production operation control module receives the heavy ladle demand information issued by the steelmaking production information system, the self-propelled torpedo ladle car production operation control module preliminarily identifies and judges the heavy ladle demand information, generates the operation instruction of the self-propelled torpedo ladle car in combination with the position information and state information of the self-propelled torpedo ladle car, and sends the operation instruction to the self-propelled torpedo ladle car:

[0041] As shown in Figure 3 , if the heavy ladle demand information only contains the demand workstations 43, 44, 45 and 46 and does not contain the torpedo ladle car number, the self-propelled torpedo ladle car production operation control module generates the operation instruction for the self-propelled torpedo ladle car closest to the heavy ladle station L1 and L2 (such as 2#) in combination with the position information of the self-propelled torpedo ladle car in the steelmaking area (i.e. the information of the parking position of the self-propelled torpedo ladle car in the steelmaking area) according to the heavy ladle demand information (such as the 46 workstation) issued by the steelmaking production information system, and sends the operation instruction to the self-propelled torpedo ladle car. The self-propelled torpedo ladle car autonomously runs to the end point of the operation instruction (such as the specified 46 workstation) under the unified command of the self-propelled torpedo ladle car production operation control module, feeds back the in-place information, completes the operation instruction, and the running route is shown by the dotted arrow in Figure 4 .

[0042] As shown in Figure 5 , if the heavy ladle demand information does not contain the demand workstations 43, 44, 45 and 46 and contains the torpedo ladle car number, the self-propelled torpedo ladle car production operation control module generates and sends the operation instruction to the specified self-propelled torpedo ladle car (such as 1#) according to the heavy ladle demand information issued by the steelmaking production information system in combination with the idle information of the workstations 43, 44, 45 and 46 in the steelmaking heavy ladle station. The self-propelled torpedo ladle car autonomously runs to any idle workstation under the unified command of the self-propelled torpedo ladle car production operation control module according to the end point of the operation instruction (i.e. any idle workstation), feeds back the in-place information, completes the operation instruction, and the running route is shown by the dotted arrow in Figure 6 .

[0043] As shown in Figure 7 , if the heavy ladle demand information contains the demand workstations 43, 44, 45 and 46 and the torpedo ladle car number, the self-propelled torpedo ladle car production operation control module generates and sends the operation instruction for the specified self-propelled torpedo ladle car to a specific workstation according to the demand workstation (such as the 44 workstation) and the torpedo ladle car number (such as 3#) information issued by the steelmaking production information system. The self-propelled torpedo ladle car autonomously runs to the specified workstation under the unified command of the self-propelled torpedo ladle car production operation control module according to the end point of the operation instruction (i.e. the specified workstation), feeds back the in-place information, completes the operation instruction, and the running route is shown by the dotted arrow in Figure 8 .

[0044] As Figure 9 shown, if the heavy tank demand information does not contain the demand work site points 43, 44, 45, 46, nor the torpedo tank car tank number, the self-propelled torpedo tank car production operation control module generates and issues operation instructions according to the idle information of the work site points 43, 44, 45, 46 in the tank dumping stations L1, L2 and the self-propelled torpedo tank car position information in the steelmaking area (i.e. the information of the parking position of the self-propelled torpedo tank car in the steelmaking area), and the self-propelled torpedo tank car runs to any idle work site according to the operation instruction end point under the unified command of the self-propelled torpedo tank car production operation control module, and feeds back the arrival information to complete the operation instruction. The running route is shown by the dashed arrow in Figure 10 .

[0045] Scenario 2: Receive the full information of the self-propelled torpedo tank car, and do not receive the heavy tank demand information of the tank dumping station.

[0046] As Figure 11 shown, if the self-propelled torpedo tank car production operation control module receives the full information of the torpedo tank car issued by the blast furnace production information system, the self-propelled torpedo tank car production operation control module selects an idle parking position according to the idle information of the parking position in the steelmaking area (such as positions 4-9) judged by the self-propelled torpedo tank car production operation control module, sets the position as the end point of the full torpedo tank car, and issues operation instructions to the torpedo tank car. The self-propelled torpedo tank car runs to the operation instruction end point according to the operation instruction end point under the unified command of the production operation control module, and feeds back the arrival information to complete the operation instruction.

[0047] Scenario 3: Do not receive the full information of the self-propelled torpedo tank car, and do not receive the heavy tank demand information of the tank dumping station.

[0048] As Figure 13As shown, if there are only six parking positions 4, 5, 6, 7, 8, 9 in the steelmaking area, when there are many heavy torpedo cars, the six parking positions will be full of torpedo cars, and the heavy torpedo cars (5 or 7) closest to the dumping stations L1, L2 enter the work stations 43, 44, 45, 46, at which time the blast furnace sends a torpedo car full information, and the self-propelled torpedo car production operation control module can only select 5 or 7 as the parking position of the torpedo car. At this time, since 6, 8, 9 in the direction from the blast furnace to the dumping station are occupied by heavy torpedo cars, the blast furnace full of molten iron torpedo cars cannot directly run to the positions 5 or 7, and need to run to the torpedo car turning point to be parked in the positions 5 or 7. This running route will occupy the section in front of the dumping stations L1, L2, seriously affecting the in-and-out car operation of the dumping stations L1, L2, resulting in reduced operation efficiency, operation safety and production rhythm of the area.

[0049] Therefore, in order to solve the parking conflict and affect the production operation when there are many heavy torpedo cars, the self-propelled torpedo car production operation control module will automatically issue an operation instruction to move the heavy torpedo cars on the positions 6, 8, 9 to the direction of the dumping stations L1, L2, and move to the positions 5, 7 before moving, to give way to the heavy torpedo cars coming from the blast furnace, so that the heavy torpedo cars coming from the blast furnace can be directly parked in the steelmaking area parking position without needing to turn at the turning point. The running route is shown by the dotted arrow in Figure 14

[0050] In summary, the molten iron transportation control method of the self-propelled torpedo car of the present application can fully use the production information of the blast furnace and steelmaking information system, replace the production organization mode of manual telephone communication of production information of the blast furnace and steelmaking, and manual dragging of issuing locomotive operation instruction of molten iron transportation scheduling, reduce the labor intensity of manual work, and improve the informatization level of molten iron transportation management.

[0051] However, those skilled in the art in the technical field should realize that the above embodiments are only used to illustrate the present application, and are not used as a limitation of the present application, and as long as the changes and modifications of the above described embodiments are within the spirit and principles of the present application, they will fall within the scope of the claims of the present application.​
