[0002] Currently, in the use of molten iron carts, there is a need to install electrically driven equipment on them. For example, in the metallurgical industry, the ladle covering technology for blast furnace molten iron transfer is gradually becoming a means of energy conservation and emission reduction for steel enterprises. Electrically driven equipment such as ladle covers is installed on dedicated molten iron carts. The molten iron carts are pulled by locomotives and do not contain their own power source, while equipment such as ladle covers needs to be electrically driven. Therefore, in order to ensure the normal operation of equipment such as ladle covers, it is necessary to supply power to the equipment such as ladle covers installed on the molten iron carts.

[0003] However, the manual connection of electricity for ladle capping has always been a major problem in the capping operation. With the improvement of automation, unmanned power supply is increasingly valued by steel mills. At present, unmanned power supply is mainly achieved by installing batteries on each molten iron car. However, this method has several drawbacks: firstly, the investment cost of batteries is too high; secondly, the batteries pose safety hazards in the high-temperature environment of the blast furnace operating area for a long time; and thirdly, the single-car fixed control mode is cumbersome and prone to misoperation.

[0004] To address this, an automatic power connection device for securely connecting molten iron cars is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a stable automatic power connection device for molten iron cars, which can solve the problems of the existing method of achieving unmanned power supply mainly by installing batteries on each molten iron car. However, this method has the following problems: firstly, the investment cost of batteries is too high; secondly, the batteries pose safety hazards in the high-temperature environment of the blast furnace operating area for a long time; and thirdly, the single-car fixed control mode is cumbersome and prone to misoperation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable molten iron car attachment automatic power connection device, comprising two mounting brackets, each mounting bracket having a fixed seat bolted to one side of its opposite side, and the two fixed seats being staggered, the bottom of the left fixed seat having a stationary contact, the top of the right fixed seat having a power connection component bolted to it, and the power connection component cooperating with the stationary contact, and both sides of the bottom of the left fixed seat having a connecting component movably arranged, and the connecting component cooperating with the power connection component;

[0007] The connecting assembly includes a card plate, a card slot is provided at the bottom of the front side of the card plate, and a card block is rotatably connected inside the card slot. The rear side of the card block is in close contact with the power connection assembly, and an electric cylinder is rotatably connected to the bottom inside the card block.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 The present invention provides the following technical solution:

[0026] An automatic power connection device for a sturdy molten iron car includes two mounting brackets 1. Each mounting bracket 1 has a fixed seat 2 bolted to one side of its opposite side, and the two fixed seats 2 are staggered. A stationary contact 3 is provided at the bottom of the left fixed seat 2, and a power connection component 4 is bolted to the top of the right fixed seat 2. The power connection component 4 works in conjunction with the stationary contact 3. Connecting components 5 are movably provided on both sides of the bottom of the left fixed seat 2, and the connecting components 5 work in conjunction with the power connection component 4.

[0027] The connecting component 5 includes a card plate 51. A card slot 52 is provided at the bottom of the front side of the card plate 51. A card block 53 is rotatably connected inside the card slot 52. The rear side of the card block 53 is in close contact with the power connection component 4. An electric cylinder 54 is rotatably connected to the bottom inside the card block 53. The other side of the electric cylinder 54 is rotatably connected to the inner wall of the card block 53.

[0028] In this embodiment: by setting the connecting component 5, when the power receiving component 4 contacts the stationary contact 3, it will enter the interior of the slot 52. At this time, the electric cylinder 54 pushes the card block 53 to rotate in the card plate 51, so that the card block 53 and the power receiving component 4 are in close contact, ensuring the connection stability during the power receiving process; and when separation is required, it can be quickly released, making it easy for the molten iron car to drive away.

[0029] Specifically, such as Figure 2 , Figure 3 As shown, the power connection assembly 4 includes a fixed cylinder 41, which is bolted to the top of the right fixed seat 2. A movable rod 42 is slidably arranged inside the fixed cylinder 41. A moving contact 43 is bolted to the top of the movable rod 42 and contacts the stationary contact 3.

[0030] Specifically, such as Figure 3 As shown, a synchronous plate 44 is sleeved on the surface of the movable rod 42, and guide telescopic rods 45 are bolted to both sides of the bottom of the synchronous plate 44. The bottom of the guide telescopic rods 45 is bolted to the right fixed seat 2.

[0031] Specifically, such as Figure 3 As shown, a return spring 46 is sleeved on the surface of the guide telescopic rod 45, and the return spring 46 is connected to the synchronous plate 44 and the right fixed seat 2 respectively.

[0032] In this embodiment: By setting the power connection component 4, in the initial state, the movable rod 42 is in a higher position under the support of the return spring 46 and the guide telescopic rod 45, and the moving contact 43 is separated from the stationary contact 3. When the molten iron car approaches and generates a squeezing effect, the movable rod 42 is forced to slide downward along the fixed cylinder 41, driving the moving contact 43 to descend and contact the stationary contact 3, thereby realizing the conduction of current, so that the power is transmitted from the stationary contact 3 to the electrical equipment of the subsequent molten iron car through the moving contact 43. When the molten iron car leaves, the return spring 46 restores its deformation and generates an upward elastic force, pushing the movable rod 42 to rise, and the moving contact 43 separates from the stationary contact 3, completing one power connection cycle.

[0033] Specifically, such as Figure 6 As shown, the top of the locking block 53 extends into the interior of the left fixed seat 2, and a connecting plate 6 is bolted between the opposite sides of the two locking blocks 53. The connecting plate 6 is slidably disposed inside the left fixed seat 2.

[0034] Specifically, such as Figure 6 As shown, hydraulic telescopic rods 7 are bolted to the side of the locking block 53 and the connecting plate 6 near the inner wall of the left fixed seat 2, and a positioning spring 8 is sleeved on the surface of the hydraulic telescopic rod 7. The side of the positioning spring 8 near the inner wall of the left fixed seat 2 is connected to it.

[0035] In this embodiment: by setting the connecting plate 6, the hydraulic telescopic rod 7 and the positioning spring 8, the positioning spring 8 and the hydraulic telescopic rod 7 can be used together to make the clamping plate 51 and the connecting plate 6 slightly displaced, so that the electrical connection component 4 can offset the offset during the operation of the molten iron car and ensure a stable and reliable electrical connection between adjacent molten iron cars.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, a pressing roller 9 is bolted to the front side of the left fixed base 2, and an inclined surface is provided on the rear side of the moving contact 43. The pressing roller 9 is used in conjunction with the inclined surface.

[0037] In this embodiment: by setting the extrusion roller 9 and the inclined plane in cooperation, the extrusion roller 9 and the inclined plane cleverly transform the horizontal movement of the molten iron car into the vertical movement of the moving contact 43, realizing the smooth and precise docking of the moving contact 43 and the stationary contact 3, and reducing the risk of damage to the electrical components from direct collision docking.

[0038] Working principle: During the molten iron car coupling process, the extrusion roller 9 first contacts the rear inclined surface of the moving contact 43. As the molten iron car continues to move, the extrusion roller 9 rolls along the inclined surface. Due to the inclined angle design of the inclined surface, a downward component force is generated on the moving contact 43 during the rolling process. This component force causes the movable rod 42 to slide downward in the fixed cylinder 41 against the elastic force of the return spring 46. As the movable rod 42 moves downward, the moving contact 43 gradually approaches the stationary contact 3 at the bottom of the left fixed seat 2, and finally the two make contact and connect to electricity. At this time, the synchronous plate 44 enters the slot 52 in the card plate 51, and then the electric cylinder 54 pushes the card block 53 to rotate in the card plate 51, so that the card block 53 makes close contact with the power connection component 4, ensuring the connection stability during the power connection process and realizing the automatic power connection work when the molten iron car is coupled.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
