During the molten iron dispatching operation, factors such as molten iron splashing and high-temperature radiation also pose a great safety hazard to the cross-carriage operator. The existing dispatching and transfer methods are relatively backward, and the operation efficiency of the cross-carriage is low. Utility Model Content

[0028] This intelligent transportation system has the following three scheduling modes:

[0029] Dispatching mode 1: On each line, only one capacitor-type molten iron cross-over vehicle is used to transfer molten iron, and the other capacitor-type molten iron cross-over vehicle is used as a standby.

The intelligent sensing system 7 can calibrate the titanium charging span lifting position and the converter charging span lifting position in the steelmaking workshop. Under normal working conditions, the vanadium charging span crane 4 is used to complete the molten iron ladle grabbing and emptying operations at the titanium charging span lifting position; when the titanium charging converter is under maintenance or an accident occurs, the capacitive molten iron span crane 2 directly enters the converter charging span lifting position and completes the molten iron ladle grabbing and emptying operations through the converter span crane 5.

[0033] Example

[0034] A capacitor cross-car vanadium titanium molten iron intelligent transportation system, such as Figure 1 As shown, it includes a swing chute iron receiving device 1, a capacitive molten iron crossing car 2, a molten iron transfer line 3, a vanadium extraction charging crossing car 4, a converter crossing car 5, a charging system 6, and an intelligent sensing system 7.

[0035] The capacitor molten iron transfer vehicle 2 receives the molten iron from the swing chute 1, and can be a single vehicle or a double vehicle linked together through the molten iron transfer line 3 to enter the vanadium charging span in the steelmaking plant. The vanadium charging span crane 4 lifts the full molten iron tank and puts the empty tank back to the capacitor molten iron transfer vehicle 2. When the vanadium extraction converter fails or cannot be put into use due to maintenance, the molten iron is transferred through the converter crane 5.

[0036] Two capacitor iron-carrying cars 2 are set on each line. Under normal circumstances of meeting the requirements of iron-carrying transportation, the following modes can be adopted for the dispatching between the cars: 1. Only one capacitor iron-carrying car swings back and forth to receive iron on each line, and the other car is on standby; the two cars switch in turn between different iron batches; 2. The capacitor iron-carrying car used for normal production will not switch with the iron batches, and the other capacitor iron-carrying car is always on standby; 3. Double-car linkage iron-carrying is adopted for molten iron transportation, the single transportation volume is large, and the dispatching time is relatively sufficient.

[0037] Figure 2It is a schematic diagram of a capacitor-type molten iron transfer vehicle. The molten iron transfer method is a capacitor-type molten iron transfer vehicle with a tank system. A capacitor pack 21 with a capacity that meets the travel requirements is set inside one end of the vehicle body, and it is equipped with an independent on-board capacitor air conditioner 22. An on-board electrical cabinet 26 and a hydraulic power station 27 for the tank cover are set inside one side of the vehicle body. The capacitor-type molten iron transfer vehicle adopts a single motor 23 and a reducer 24 with a balanced wheel set structure. The capacitor-type molten iron transfer vehicle 2 is designed with two independent motors 23 and reducers 24. After a power unit fails, it can continue to operate to meet the blast furnace molten iron transfer requirements. Since the capacitor charging time is much shorter than that of general battery-type power sources, the charging waiting time of the capacitor-type molten iron transfer vehicle is greatly shortened, thereby improving the utilization rate of the capacitor-type molten iron transfer vehicle, improving the molten iron transfer efficiency, and reducing the scheduling rhythm requirements.

[0038] The bottom of the capacitive iron molten cross-over vehicle is equipped with a FRID wireless radio frequency transmitter, and reading tags and mechanical limits are set at the node positions such as the deceleration position, parking position and limit position of the cross-over line. The capacitive iron molten cross-over vehicle completes deceleration, parking and other actions through the wireless tag recognition system. The capacitive iron molten cross-over vehicle is equipped with a set of laser rangefinders at the front and rear, and the reflector is arranged on the ground; the capacitive iron molten cross-over vehicle is also equipped with an on-board iron molten weighing system; the vehicle driving information, weighing information and other data are transmitted to the receiving end through wireless transmission and uploaded to the control center in real time.

[0039] Figure 2 In the figure, the on-board automatic charging terminal 28 connected to the on-board capacitor pack 21 is an electro-hydraulic push rod telescopic structure. After reaching the set automatic charging point and receiving the alignment signal, the on-board charging mechanism is stretched by the electro-hydraulic push rod to connect with the ground automatic charging terminal 29, and the ground automatic charging terminal 29 is connected to the ground power cabinet 210 through a cable. In order to ensure the safe distance between the vehicle body and the two sides, the extension width of the on-board electric charging mechanism needs to be shortened as much as possible.

[0040] Two sets of charging facilities are installed on each line. One set is installed in front of the cross-line car barrier under the platform of the blast furnace iron-making yard. In order not to affect the two vehicles entering the steelmaking workshop at the same time, the other set is installed at the second column entering the steelmaking plant. Each set of automatic charging facilities is equipped with a charging cabinet connected to an external power supply, and the charging cabinet is equipped with a manual charging head. Under normal working conditions, the capacitive molten iron cross-line car is connected to the automatic head for charging. In the event of an accident, manual charging is used.

[0041] Figure 3It is a schematic diagram of the intelligent sensing system for molten iron transportation. A sensing camera is set at each iron-out point to determine whether the iron-out process is completed. The sensing camera set before entering the steel-making workshop door is used to determine whether to agree to enter the steel-making workshop for hoisting. A moving tank warning light is set at the hoisting position to remind the surrounding personnel that the tank hoisting operation is in progress. The crossing laser radar 72 is used to determine whether there is an obstacle intruding into the line. Specifically, the iron-out side sensing camera 71 is used to detect and identify the iron-out process and whether the iron-out has started or ended. After the iron-out is completed and the release instruction is received, the capacitive molten iron crossing vehicle 2 drives out of the iron-out yard. If the crossing laser radar 72 detects that an obstacle has intruded into the line, it will issue a stop command signal to the moving capacitive molten iron crossing vehicle. Before arriving at the steel-making workshop door, the steel-making side sensing camera 73 identifies the capacitive molten iron crossing vehicle 2 that is about to enter the plant, and gives a signal whether it can enter according to the situation in the steel-making plant. At the tank hanging positions of the vanadium extraction span and the converter span, there are corresponding vanadium extraction span moving tank warning lights 74 and converter span moving tank warning lights 75 to warn and remind the tank hanging operation. All sensing signals interact with the control center through industrial WIFI76.

[0042] The utility model adopts a capacitive molten iron cross-carriage with an intelligent sensing system and a new wireless automatic charging system, which effectively solves the problems of low transportation efficiency of cross-carriages and poor working environment for operators, and has broad market application prospects.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
