Description

Technical Field

[0001] This utility model relates to the field of molten iron transfer technology, specifically to a molten iron transfer device used in the production of cast iron pots. Background Technology

[0002] In the production of iron pots, iron ore is melted in a smelting furnace to become pig iron. Molten iron is then collected in a molten iron ladle in front of the furnace and transported by a transfer device to the casting area for pouring. The transfer device typically consists of a molten iron ladle and a tractor. The molten iron ladle is used to hold the molten iron and must be resistant to high temperatures and corrosion. The tractor is used to pull the molten iron ladle and must have sufficient traction and stability.

[0003] Existing molten iron transfer equipment is prone to problems during transport. When metal slag or impurities fall from the ground and come into contact with the transfer device, the device will vibrate slightly, causing the molten iron inside the ladle to splash out through the top opening. Furthermore, since there is no restraint on the molten iron ladle, it may rotate on the transfer device or even tip over, making the transfer process very dangerous. Utility Model Content

[0004] The purpose of this invention is to provide a molten iron transfer device for the production of cast iron pots, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a molten iron transfer device for the production of cast iron pots, comprising a transfer car, two support frames fixedly connected to the top of the transfer car, a molten iron ladle rotatably connected to the top of the two support frames, two protective covers provided on the top of the molten iron ladle, and both sides of the two protective covers rotatably connected to the transfer car.

[0006] The top of the transfer vehicle is fixedly connected to two motors at both ends. The output ends of the two motors are fixedly connected to threaded rods. The outer walls of the two threaded rods are threaded with movable mechanisms. The top ends of the two movable mechanisms are rotatably connected to two protective covers respectively.

[0007] Preferably, the top of the transfer vehicle is provided with two limiting slide rails, and the two movable mechanisms include movable blocks. The middle part of the movable block is threadedly connected to the threaded rod, and the bottom of the movable block is provided with a limiting groove. The inner wall of the limiting groove is slidably connected to the limiting slide rail.

[0008] Preferably, two movable wheels are rotatably connected to both sides of the movable block, the bottom of the movable wheels is rotatably connected to the transfer vehicle, and a connecting rod is rotatably connected to the top of the movable block. The end of the connecting rod away from the movable block is rotatably connected to the protective cover.

[0009] Preferably, the protective cover includes a top cover body, with two plugging blocks fixedly connected to the bottom of the top cover body. The two plugging blocks of the top cover body are staggered from each other. An L-shaped pull member is fixedly connected to the top of the top cover body. The two sides of the L-shaped pull member are rotatably connected to the support frame. A fixing rod is fixedly connected to the top of the L-shaped pull member. The outer wall of the fixing rod is rotatably connected to the movable block.

[0010] Preferably, the molten iron ladle includes a molten iron ladle body, with rotating shafts fixedly connected to both sides of the molten iron ladle body. The bottom of both rotating shafts is rotatably connected to the molten iron ladle body, and a limit block is fixedly connected to the end of the rotating shaft away from the molten iron ladle body.

[0011] Preferably, the molten iron ladle body has a pouring opening on both sides of the top, and a pulling member is fixedly connected to both sides of the bottom of the molten iron ladle body.

[0012] Preferably, a fixing block is fixedly connected to the middle of the connecting rod, and a slot is provided on one side of the fixing block. When the bottom of the top cover body is in contact with the top of the molten iron ladle body, the bottom of the limiting block is inserted into the inner wall of the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a molten iron transfer device for cast iron pot production. It optimizes the existing molten iron transfer device structure by using two motors to drive a threaded rod to rotate and a movable block to move along a limiting slide rail. The movable block then drives a connecting rod to pull a fixed rod, which in turn drives an L-shaped puller to rotate the top cover body downwards on the support frame until the four plugging blocks are in contact with the bottom of the two pouring openings. This achieves rapid sealing of the top opening of the molten iron pot by the protective cover, preventing molten iron from splashing out. Simultaneously, the connecting rod drives the fixed block to move, causing the limiting block to insert into the slot, thus restricting the rotation of the limiting block and preventing the molten iron pot from rotating and tipping over during transportation, which could cause danger.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see the appendix Figure 1-4 This application provides the following technical solutions.

[0022] A molten iron transfer device for cast iron pot production includes a transfer car 1. Two support frames are fixedly connected to the top of the transfer car 1. A molten iron ladle 5 is rotatably connected to the top of the two support frames. Two protective covers 6 are provided on the top of the molten iron ladle 5, and both sides of the two protective covers 6 are rotatably connected to the transfer car 1. Two motors 2 are fixedly connected to both ends of the top of the transfer car 1. Threaded rods 3 are fixedly connected to the output ends of the two motors 2. Movable mechanisms 4 are threadedly connected to the outer walls of the two threaded rods 3. The top ends of the two movable mechanisms 4 are rotatably connected to the two protective covers 6 respectively. Two limiting slide rails 7 are provided on the top of the transfer car 1. The two movable mechanisms 4 include movable blocks 41. The middle part of the movable block 41 is threadedly connected to the threaded rod 3, and the bottom of the movable block 41 has an opening... There is a limiting groove 42, the inner wall of which is slidably connected to the limiting slide rail 7. Two movable wheels 43 are rotatably connected to both sides of the movable block 41. The bottom of the movable wheels 43 is rotatably connected to the transfer car 1. A connecting rod 44 is rotatably connected to the top of the movable block 41. The end of the connecting rod 44 away from the movable block 41 is rotatably connected to the protective cover 6. The protective cover 6 includes a top cover body 61. Two plugging blocks 64 are fixedly connected to the bottom of the top cover body 61. The plugging blocks 64 of the two top cover bodies 61 are staggered. An L-shaped pull member 62 is fixedly connected to the top of the top cover body 61. The two sides of the L-shaped pull member 62 are rotatably connected to the support frame. A fixing rod 63 is fixedly connected to the top of the L-shaped pull member 62. The outer wall of the fixing rod 63 is rotatably connected to the movable block 41.

[0023] It should be noted that when the molten iron ladle 5 is used to receive molten iron in front of the smelting furnace and then transported to the casting mold for pouring, the operator starts two motors 2 to drive two threaded rods 3 to rotate. The threaded rods 3 and the movable block 41 make threaded movements. Through the limiting slide rail 7 and the limiting groove 42, the movable block 41 moves linearly on the top of the transfer car 1 via the bottom movable wheel 43. The movable block 41 drives the top connecting rod 44 to rotate, pushing the fixed rod 63 to move. The fixed rod 63 drives the L-shaped pull member 62 to rotate on the support frame. The L-shaped pull member 62 drives the top cover body 61 to rotate downward until the top cover body 61 is in contact with the top of the molten iron ladle body 51. The four plugging blocks 64 are inserted into the pouring port 52 to quickly seal the top of the molten iron ladle 5, preventing the molten iron from vibrating due to pressure on objects or entering through the opening at the top of the molten iron ladle body 51 during transfer, which would cause the molten iron to splash out.

[0024] The molten iron ladle 5 includes a molten iron ladle body 51. Rotating shafts 54 are fixedly connected to both sides of the molten iron ladle body 51. The bottom of both rotating shafts 54 is rotatably connected to the molten iron ladle body 51. A limiting block 55 is fixedly connected to the end of the rotating shaft 54 ​​away from the molten iron ladle body 51. A pouring port 52 is opened on both sides of the top of the molten iron ladle body 51. Pulling members 53 are fixedly connected to both sides of the bottom of the molten iron ladle body 51. A fixing block 45 is fixedly connected to the middle of the connecting rod 44. A slot 46 is opened on one side of the fixing block 45. When the bottom of the top cover body 61 is in contact with the top of the molten iron ladle body 51, the bottom of the limiting block 55 is inserted into the inner wall of the slot 46.

[0025] It should be noted that when the connecting rod 44 moves, it pushes the fixing block 45 to move. The fixing block 45 causes the limiting block 55 to be inserted into the slot 46, which restricts the rotation of the rotating shaft 54 ​​and prevents the molten iron ladle 5 from rotating during transportation, causing it to tip over and resulting in a dangerous accident.

[0026] When molten iron is received in front of the smelting furnace using the molten iron ladle 5 and then transported to the casting mold for pouring, the operator starts two motors 2 to drive two threaded rods 3 to rotate. The threaded rods 3 make threaded movements with the movable block 41. Through the limiting slide rail 7 and the limiting groove 42, the movable block 41 moves linearly on the top of the transfer car 1 via the bottom movable wheel 43. The movable block 41 drives the top connecting rod 44 to rotate, pushing the fixed rod 63 to move. The fixed rod 63 drives the L-shaped pull member 62 to rotate on the support frame. The L-shaped pull member 62 drives the top cover body 6. 1. Rotate downwards until the top cover body 61 is in contact with the top of the molten iron ladle body 51. The four plugging blocks 64 are inserted into the pouring port 52 to quickly seal the top of the molten iron ladle 5. This prevents the molten iron from vibrating due to pressure on objects or entering through the opening at the top of the molten iron ladle body 51 during transfer, which could cause the molten iron to splash out. At the same time, when the connecting rod 44 moves, it will push the fixing block 45 to move. Through the fixing block 45, the limiting block 55 is inserted into the slot 46, which restricts the rotation of the rotating shaft 54 ​​and prevents the molten iron ladle 5 from rotating and tipping over during transfer, which could lead to a dangerous accident.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
