Description

Technical Field

[0001] The utility model relates to the technical field of hot metal transportation systems, and particularly relates to a hot metal transportation system with a supercapacitor power supply. Background Art

[0002] The one-pot hot metal transportation process is a new process at the ironmaking-steelmaking interface, which has multiple functions such as BF hot metal receiving, transportation, buffer storage, hot metal pretreatment, converter hot metal charging, rapid container turnover, and hot metal heat preservation. Due to its characteristics of small ladle tipping operation volume, short process flow, compact equipment layout, less dust pollution, and small hot metal temperature drop, it has gradually replaced the traditional torpedo car for ladle tipping operation production process, and has significant economic, environmental and social benefits.

[0003] The one-pot hot metal transportation process is a rigid one-pot transportation system based on a wide-gauge hot metal transport vehicle. After receiving hot metal from under the BF, the hot metal is directly transported to the steelmaking workshop by the hot metal transport vehicle through the hot metal transportation line. Among them, the hot metal transport vehicle is the core equipment of the one-pot transportation system. In the prior art, the power supply of the hot metal transport vehicle mainly relies on cable reel power supply or trolley wire power supply. The problem with cable power supply is that the cable is easily burned by high-temperature hot metal, and the cable is dragged during the reciprocating movement of the vehicle, and its service life is only 4-6 months. And the cost of the cable is relatively high, so the use cost of the cable power supply scheme is relatively high. The trolley wire power supply structure needs to be set at a certain height from the ground, which will cause obstacles to the surrounding personnel and vehicle traffic, and is prone to collision with the crane hook, thus having an adverse impact on the overall production efficiency.

[0004] It can be known from the above background art that the power supply methods adopted by the current hot metal transport vehicles for the one-pot hot metal transportation process have the problems of high use cost and easy influence on the overall production efficiency. Content of the Utility Model

[0005] In view of this, the utility model aims to propose a hot metal transportation system with a supercapacitor power supply, which solves the defects of high use cost and easy influence on the overall production efficiency existing in the power supply method of the hot metal transport vehicle in the background art.

[0006] To achieve the above object, the technical solution of the utility model is realized as follows:

[0007] A hot metal transportation system with a supercapacitor power supply of the utility model includes

[0008] A transportation track, one end of which is connected to the BF ironmaking work area and the other end is connected to the converter steelmaking work area;

[0009] A transportation vehicle group, which includes

[0010] a transport vehicle, the transport vehicle being arranged on the transport track,

[0011] a power supply vehicle, the power supply vehicle being arranged on the transport track,

[0012] A connector, one end of which is connected to the carrier vehicle, and the other end of which is connected to the power supply vehicle.

[0013] By adopting the above technical scheme, the transport track in the present application is a passage vertically connected between the ironmaking workshop and the steelmaking workshop, which plays a role of limiting and bearing the transport vehicle group. The transport vehicle group includes a power supply vehicle and a carrier vehicle. The carrier vehicle plays a bearing role for the molten iron ladle. The power supply vehicle plays a driving and pulling role for the carrier vehicle. The connector plays the role of connecting the carrier vehicle and the power supply vehicle. The split design of the power supply vehicle and the carrier vehicle allows the power supply vehicle to be separated from the carrier vehicle during the iron receiving process of the carrier vehicle and run alone to the charging position for charging, which significantly improves the overall transportation efficiency of the present application. At the same time, compared with the cable power supply and busbar power supply methods in the prior art, the traction drive method of the power supply vehicle is safe and flexible, has a long service life, can meet the requirements of harsh working conditions, ensures the continuity of the transportation process, and achieves the invention purpose of reducing the use cost and improving production efficiency.

[0014] Furthermore, the power supply vehicle comprises:

[0015] A vehicle body, the vehicle body being arranged on the transport track;

[0016] A supercapacitor, wherein the supercapacitor is arranged on the vehicle body;

[0017] A drive motor, wherein a power output shaft of the drive motor is connected to the rotating shaft of the vehicle body and is electrically connected to the supercapacitor.

[0018] By adopting the above technical solution, the car body supports and limits the other parts of the power supply car structure and can move along the transport track. The supercapacitor installed on the car body acts as an energy storage container. Using supercapacitors as energy storage containers can significantly shorten the charging time, and has high reliability and strong environmental adaptability.

[0019] Furthermore, the power supply vehicle also includes a brake, which is arranged at the bottom of the vehicle body.

[0020] By adopting the above technical solution, the brake arranged at the bottom of the vehicle body can realize the braking function, so that the vehicle body can be accurately stopped at the specified position. At the same time, the vehicle body speed can be linearly controlled to reduce the impact and shaking of the vehicle body and avoid the occurrence of molten iron spilling accidents.

[0021] Further, it further includes a power supply device which is arranged on one side of the transportation track and used to charge the transportation vehicle group.

[0022] By adopting the above technical solution, the power supply device can charge the power vehicle in the transportation vehicle group. The structure that the power supply device is arranged on one side of the transportation track enables the power vehicle to start charging when it moves to the designated position on the transportation track, further improving the charging efficiency and the overall automation level of this application.

[0023] Further, a plurality of power supply devices are provided, and the plurality of power supply devices are equidistantly distributed along the length direction of the transportation track.

[0024] By adopting the above technical solution, the structural design of equidistantly arranging a plurality of power supply devices enables this application to charge a plurality of power vehicles simultaneously, further improving the efficiency of the charging process.

[0025] Further, it further includes a power supply room which is arranged on one side of the transportation track near one end of the converter steelmaking work area and is electrically connected to the power supply device.

[0026] By adopting the above technical solution, the power supply room can supply power to the power supply device, and can cooperate with the power supply device to realize functions such as communication with the hot metal transport vehicle, uploading charging information, issuing charging or power-off instructions to the power supply device, and confirming the connection status between the hot metal transport vehicle and the power supply device.

[0027] Further, the connector includes:

[0028] A coupler, both ends of which are respectively arranged on the carrier vehicle and the power vehicle;

[0029] A control mechanism;

[0030] The control mechanism includes

[0031] A lifting member, the lifting end of which is connected to the connecting pin of the coupler and is used to change the connection state of the coupler,

[0032] A position sensor which is arranged on the connecting pin of the coupler and is used to detect the connection state of the coupler.

[0033] By adopting the above technical solution, the coupler with both ends respectively arranged on the carrier vehicle and the power vehicle realizes the functions of electrical transmission and torque transmission. On the one hand, it can enable the carrier vehicle to move along the transportation track with the power vehicle, and on the other hand, it can realize electrical connection. The lifting member in the control mechanism is an actuating element and can drive the connecting pin of the coupler to move up and down, thereby changing the connection state of the coupler. The position sensor in the control mechanism can detect the position information of the connecting pin of the coupler and convert it into an electrical signal as the basis for controlling the lifting member to perform actions.

[0034] Further, the control mechanism is electrically connected to the super capacitor.

[0035] By adopting the above technical solution, the structural design that the control mechanism is electrically connected to the super capacitor enables the control mechanism to read the power state of the super capacitor, thereby controlling the separation of the coupler and enabling the power vehicle to separate from the carrier vehicle and drive independently to the power supply device for charging.

[0036] Further, the control mechanism further includes a speed sensor, and the speed sensor is used to detect the instantaneous speed and acceleration of the power vehicle.

[0037] By adopting the above technical solution, the speed sensor in the control mechanism can detect the instantaneous speed and acceleration of the power vehicle and the carrier vehicle, so as to cooperate with the brake to control the speed of the carrier vehicle within a reasonable range, and while ensuring the production efficiency as much as possible, the accident of molten iron splashing out can be avoided.
