Description

Technical Field

[0001] The present invention relates to a self-propelled intelligent molten iron car, and in particular to a self-propelled intelligent molten iron car applied in the field of molten iron cars. Background Art

[0002] A molten iron car is a piece of equipment used by metallurgical enterprises to transport molten iron from blast furnaces to steel mills, iron casting machines or foundries for steelmaking. In order to avoid large heat loss in the molten iron due to the open design when transporting molten iron in ladles, which in turn affects the quality of the molten iron, a covered ladle method has achieved good results. However, when using a molten iron car with an insulation cover, the molten iron inside still shakes during transportation, which is not conducive to the stable transportation of the molten iron.

[0003] The specification of Chinese invention patent CN202211164040.0 discloses an automatic opening and closing device for the cover of a locomotive powered molten iron tank. This solution utilizes the movement of a rail locomotive in conjunction with the action of a sheet metal frame to open the tank covers in sequence, effectively reducing the problem of insufficient power caused by excessive power reduction of the rail locomotive due to simultaneous opening of the covers, thereby improving the practicality of the device. The automatic opening and closing of the tank cover can reduce the tediousness and danger of manual operation, improve the safety of the device, and at the same time improve the working efficiency of the device and reduce energy consumption. During emergency braking of the rail locomotive, the surging molten iron is drained through the liquid guide channel, consuming a large amount of kinetic energy and returning to the molten iron tank, reducing the situation in which the molten iron tank becomes unstable and overturns due to the surging molten iron. The structure with a high middle and low ends is used to reduce the adhesion of molten iron to the inside of the liquid guide channel, thereby avoiding the problem of the liquid guide channel being blocked.

[0004] When opening the insulation cover, the above-mentioned equipment uses the inertia of the molten iron car after it stops after driving to simplify the opening process. However, at this time, the molten iron inside the molten iron car is in a shaking and overflowing state. If the insulation cover is opened at this time, the high-temperature molten iron will overflow into the molten iron tank, which will not only easily cause scalding accidents, but also cause unnecessary waste of molten iron. Summary of the Invention

[0012] As a further improvement of the present application, the distance between the bottom end of the insulating isolation block and the bottom end of the longitudinal groove is greater than the height of the insulating isolation block itself.

[0013] As another improvement of the present application, the surface of the return spring is coated with an insulating thermal insulation coating and a wear-resistant coating located outside the insulating thermal insulation coating.

[0032] The following describes three implementation methods of the present application in detail with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-8 A self-propelled intelligent molten iron car is shown, comprising a frame 1, a molten iron ladle 2 is mounted on the top of the frame 1, an insulation cover 4 is movably connected to the top of the molten iron ladle 2, a bracket 3 symmetrically arranged about the molten iron ladle 2 is mounted on the top of the frame 1, a covering system 5 is mounted on the top of the bracket 3, an unpowered bogie 6 is mounted on one end of the bottom of the frame 1, a driven bogie 7 is mounted on the other end of the bottom of the frame 1, buffer blocks 8 are connected to both ends of the frame 1, a covering hydraulic station 9 is mounted on one end of the top of the frame 1, a power supply system 10 is mounted on the other end of the top of the frame 1, and an electrical control system 11, a communication system 12 and an environmental perception system 13 are mounted in front of the power supply system 10 in sequence.

[0035] Specifically, the environment perception system 13 senses the surrounding environment and uses algorithms to automatically warn or stop the vehicle if it encounters pedestrians or obstacles on the route.

[0036] The power supply source of the power supply system 10 is a built-in vehicle battery, an external vehicle battery or a connection to an external power grid, and the power supply option of the power supply system 10 can be freely selected from the three power supply sources;

[0037] The electrical control system 11 has a built-in wireless communication module, and the wireless communication module is configured to communicate with the communication modules of other frames 1 and with an external network controller using the communication system 12, so that the molten iron car can receive wireless signals to perform actions such as running and braking without manual operation, and run according to the established organization and scheduling procedures, with full intelligent and unmanned operation;

[0038] The driving bogie 7 is the driving source for the frame 1, driving the unpowered bogie 6 to perform corresponding driving operations, thereby driving the frame 1 to travel and transport molten iron;

[0039] The capping hydraulic station 9 cooperates with the high-temperature oil cylinder 53 in the capping system 5 to provide corresponding hydraulic expansion and contraction processing;

[0040] The buffer block 8 is an elastic structure, which provides buffering and anti-impact protection for the end of the frame 1 to prevent damage to the frame 1 caused by rigid contact;

[0041] When using the covering system 5 to provide automatic opening and closing processing for the insulation cover 4 to realize unmanned and intelligent operation, the contact between the insulation cover 4 and the molten iron inside the molten iron tank 2 can also be used to reversely act on the covering system 5, so as to prevent the covering system 5 from opening when the molten iron inside the molten iron tank 2 is in a shaking and agitated state, avoid the overflow of molten iron, and ensure the safety of the insulation cover 4 during the opening process.

[0042] The covering system 5 includes a main frame 52, one end of the main frame 52 is connected to the surface of the bracket 3 through a shaft, a high-temperature oil cylinder 53 electrically connected to the electrical control system 11 is installed on the top of the bracket 3 through a shaft, and the tail end of the high-temperature oil cylinder 53 is connected to the surface of the main frame 52 through a shaft, and a symmetrically arranged connecting frame 1 51 is installed on the surface of the main frame 52 through a shaft, and a connecting frame 2 54 is installed on the surface of the main frame 52, and the tail ends of the connecting frame 1 51 and the connecting frame 2 54 are both connected to the surface of the insulation cover 4.

[0043] Specifically, by extending and retracting the high-temperature oil cylinder 53, the main frame 52 is driven to change state, thereby driving the connecting frame 1 51 and the connecting frame 2 54 to move, thereby driving the insulation cover 4 to open or close, realizing corresponding automatic processing.

[0044] A circular groove is provided at the bottom of the thermal insulation cover 4, and an upper cover plate 41 and a lower cover plate 42 are inlaid and installed inside the circular groove. An arc-shaped overflow channel 43 is provided inside the lower cover plate 42, and both ends of the arc-shaped overflow channel 43 pass through the bottom of the lower cover plate 42. The thermal insulation cover 4 and the lower cover plate 42 are both made of thermal insulation materials, and the upper cover plate 41 is made of insulating material.

[0045] Specifically, the design of the arc-shaped overflow channel 43 can allow the swirling molten iron to move therein, thereby causing the loss of its kinetic potential energy, thereby alleviating the amplitude of the swaying and agitation;

[0046] At the same time, the design of the upper cover plate 41 and the lower cover plate 42 can greatly reduce the influence of the high temperature of the molten iron on the upper cover plate 4, thereby reducing the stability of the internal circuit after connection.

[0047] The upper cover plate 41 has a longitudinal groove 410 formed inside, and a transverse groove 411 formed on the sidewall of the longitudinal groove 410. A compression spring 46 is mounted on the inner wall of the transverse groove 411, and a metal sheet 47 is connected to the tail end of the compression spring 46. A return spring 48 is mounted on the top wall of the longitudinal groove 410, and an insulating spacer 49 is connected to the tail end of the insulating spacer 49. A sealing cable 45 is connected to the tail end of the sealing cable 45, which extends through the interior of the arc-shaped overflow channel 43 and is connected to a follower ball 44.

[0048] The initial state of the compression spring 46 is a compressed state, and the metal sheet 47 and the compression spring 46 are conductive. The metal sheet 47 is electrically connected to the electrical control system 11 .

[0049] Specifically, when the molten iron inside the molten iron tank 2 is shaken and agitated, the molten iron moves along the arc-shaped overflow channel 43, and then has an impact on the follower ball 44 inside, causing the follower ball 44 to move along the direction of the molten iron flow, and then has a pulling effect on the sealing rope 45, driving the insulating isolation block 49 to fall, so that the metal sheets 47 that were originally in a separated state can be smoothly fitted together to form a closed loop, and then an electrical signal is sent to the high-temperature oil cylinder 53 through the electrical control system 11. At this time, the high-temperature oil cylinder 53 will not start to open the insulation cover 4, thereby avoiding safety accidents caused by the overflow of the agitated molten iron after the insulation cover 4 is opened.

[0050] The distance between the bottom end of the insulating isolation block 49 and the bottom end of the longitudinal groove 410 is greater than the height of the insulating isolation block 49 itself.

[0051] Specifically, the height difference design ensures that the insulating isolation block 49 will not continue to be located in the middle of the metal sheet 47 after it falls, thereby ensuring that the two metal sheets 47 are smoothly squeezed and fitted together to close the circuit.

[0052] Second implementation method:

[0053] Figure 8-10 , wherein components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals. For simplicity, only the differences from the first embodiment are described below. This second embodiment differs from the first embodiment in that the surface of the return spring 48 is coated with an insulating and heat-insulating coating 482 and a wear-resistant coating 481 located outside the insulating and heat-insulating coating 482. The return spring 48 has a hollow cavity within it, and an inner core airbag layer 483 is disposed within the hollow cavity.

[0054] Specifically, in this embodiment, the overlapping pressing contact area of ​​the two metal sheets 47 does not need to reach 100%, but only needs to reach more than 90%;

[0055] After the insulating isolation block 49 falls, the return spring 48 is stretched synchronously. At this time, the return spring 48 is clamped between the two metal sheets 47. In order to prevent the rigid resistance of the return spring 48 from causing the pressed overlapping contact area of ​​the two metal sheets 47 to be less than 90%, a return spring with an inner core airbag layer 483 arranged inside is specially adopted. When pressed by the metal sheet 47, the inner core airbag layer 483 inside the return spring 48 in the pressed state is squeezed, and the gas is transferred to the upper unpressed inner core airbag layer 483, reducing the rigid resistance and resistance area of ​​the return spring 48 in the pressed state, ensuring that the overlapped pressed contact area of ​​the two metal sheets 47 can reach more than 90%, thereby achieving circuit closure.

[0056] During this process, the insulating and heat-isolating coating 482 and the wear-resistant coating 481 can be used to prevent the molten iron temperature from expanding the internal core airbag layer 483, ensuring that the internal core airbag layer 483 can be smoothly flattened and assisting the closing and pressing of the metal sheet 47.

[0057] The third implementation method:

[0058] Figure 11-13 , wherein the same or corresponding components as those in the first embodiment are designated by the corresponding reference numerals. For simplicity, only the differences from the first embodiment are described below. This third embodiment differs from the first embodiment in that: a spirally designed air column 484 is connected to the tail end of the return spring 48, and both the insulating spacer 49 and the air column 484 are made of thermally conductive silicone.

[0059] The elastic force of the return spring 48 is greater than the elastic force of the compression spring 46 , and the cross-sectional area of ​​the longitudinal groove 410 is greater than the cross-sectional area of ​​the insulating isolation block 49 .

[0060] Specifically, in this embodiment, both ends of the sealing cable 45 are made of heat-insulating material, the middle section is made of heat-conducting material, and the ratio of the length of the heat-insulating material to the length of the heat-conducting material is controlled at 1:9-2:8;

[0061] When the molten iron inside the molten iron ladle 2 is in a sloshing and agitated state, the heat-insulating material at the end of the sealing cable 45 near the insulating spacer 49 is sunk into the connection between the lower cover plate 41 and the upper cover plate 42, preventing the heat of the molten iron from adversely affecting the closed circuit formed by the metal sheet 47 and the pressing spring 46;

[0062] After the molten iron inside the molten iron tank 2 is in a stable state, the follower ball 44 loses its impact effect. At this time, the reset spring 48 drives the insulating isolation block 49 upward to press against the bottom of the metal sheet 47, driving the heat-conducting part of the sealing link 45 into the longitudinal groove 410. At this time, the heat of the molten iron inside the molten iron tank 2 is transferred to the longitudinal groove 410 in small quantities through the heat-conducting part, causing the air column 484 to expand, destroying the overlapping and pressing contact state between the metal sheets 47. Subsequently, under the elastic action of the reset spring 48, the insulating isolation block 49 is driven to deform and rise in the gap opened by the two metal sheets 47, and is re-isolated in the middle of the two metal sheets 47, completely interrupting the closed circuit, so that the high-temperature oil cylinder 53 can be smoothly opened to realize the cover opening operation.

[0063] In order to avoid heat accumulation in the longitudinal groove 410 in the upper cover plate 41, a heat sink is designed to penetrate the outside of the molten iron tank 2 and is connected to the upper cover plate 41. This can avoid heat accumulation in the longitudinal groove 410. In addition, since the heat transmitted through the sealing link 45 is limited and small, the heat dissipation has little impact on the heat inside the molten iron tank 2, and will not substantially damage the insulation effect of the insulation cover 4 and the lower cover plate 42 on the molten iron inside the molten iron tank 2.

[0064] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
