[0002] When using scrap steelmaking, the materials added to the steelmaking furnace are complex, including materials with large weight and volume. Currently, the materials are added to the steelmaking furnace through a packing trolley. After entering the furnace mouth through the packing trolley, the materials fall downwards and may collide with the inner wall of the steelmaking furnace, causing damage to the inner wall of the crucibles inside the steelmaking furnace. This is especially true when using graphite crucibles for steelmaking, where the graphite crucibles are more easily damaged. Utility Model Content

[0017] Please see Figures 1-3 This utility model provides the following technical solution: a steelmaking furnace charging device, including a C-shaped suspension support 1, with two vertically spaced binding support rods 11 fixedly connected to the inner wall of the C-shaped suspension support 1, at least two suspension steel wires 12 bound to the binding support rods 11, a vertical adjustment rope 2 fixedly connected to the top of the C-shaped suspension support 1, a screw thread sleeve 3 provided above the vertical adjustment rope 2, a drive screw 31 threadedly connected to the inner wall of the screw thread sleeve 3, a guide ring 32 fixedly connected to the bottom end of the screw thread sleeve 3, the vertical adjustment rope 2 passing through the guide ring 32, and support plates 4 rotatably connected to both ends of the drive screw 31.
[0018] In this implementation plan: When filling heavy materials, workers tie the suspension wire 12 to the heavy materials, wrapping it multiple times to improve stability. Then, the other end of the suspension wire 12 is wrapped multiple times to the outer wall of the two binding support rods 11. The electric winding roller 21 then winds up the vertical adjusting rope 2, lifting the C-shaped suspension support 1 upwards. This, in turn, lifts the heavy materials via the suspension wire 12. Subsequently, the drive motor 33 drives the drive screw 31 to rotate, causing the screw thread sleeve 3 to move laterally along the drive screw 31, thus lifting the heavy materials. As the material moves to the top of the steelmaking furnace's packing inlet, the electric winding roller 21 simultaneously winds up the vertical adjusting rope 2 to maintain the C-shaped suspension support 1 at a suitable height. Then, the electric winding roller 21 gradually releases the vertical adjusting rope 2, and the heavy object slowly falls under gravity until it touches the bottom and contacts the steelmaking furnace. During this process, the suspension wire 12 extends into the molten steel in the furnace and melts after a certain time. Subsequently, the vertical adjusting rope 2 and the screw thread sleeve 3 drive the C-shaped suspension support 1 to reset. The diameter of the suspension wire 12 is selected to be two to three millimeters. The device, measuring 1 meter, can remain unmelted for a sufficient time in molten steel at 1600 degrees Celsius and possesses sufficient strength to suspend and support heavy materials. After the heavy material is filled, if the suspension wire 12 has not yet melted, workers use wire cutters to cut it. The height of the U-shaped suspension support 1 is adjusted using the vertical adjustment rope 2, and the horizontal position of the U-shaped suspension support 1 is adjusted using the threaded sleeve 3 and the drive screw 31. Combined with the binding and suspension of the heavy material using the suspension wire 12, the device can extend into the molten steel inside the steelmaking furnace. The filling of heavy materials is more stable, so as to avoid the heavy materials falling into the steelmaking furnace during filling, thus avoiding damage to the inner wall of the steelmaking furnace crucible and preventing molten steel from splashing. When cutting the suspension wire 12, the gap between the two binding support rods 11 is used to cut the suspension wire 12, so that the remaining part of the suspension wire 12 can be removed from the binding support rods 11. The gap between the two binding support rods 11 can give way to the hydraulic clamp, so that the wire cutters can be inserted into the space to clamp the suspension wire 12.
[0019] The outer wall of the upper binding support rod 11 is fixedly connected with several spaced-apart barrier rings 13, and the suspension steel wire 12 corresponds to the position of the spaced-apart barrier rings 13. By setting the spaced-apart barrier rings 13, the suspension steel wire 12 can be limited. When the suspension steel wire 12 is tied and wrapped, it is wrapped according to the position of the spaced-apart barrier rings 13 to prevent the suspension steel wire 12 from getting close to each other when it is suspended and contracted by the heavy object, so that personnel can cut the single strand of suspension steel wire 12.
[0020] One end of the vertical adjustment rope 2 is fixedly connected to an electric winding roller 21, which is fixedly connected to the top of one of the support plates 4. The electric winding roller 21 can be used to wind and adjust the vertical adjustment rope 2, and the support plate 4 supports the electric winding roller 21.
[0021] One end of the drive screw 31 is fixedly connected to a drive motor 33, which is fixedly connected to the top of another support plate 4; the drive motor 33 can drive the drive screw 31 to rotate.
[0022] A connecting plate 41 is fixedly connected to the top of the support plate 4; the connecting plate 41 is installed on the support frame or the inner wall of the building top to support the support plate 4.
[0023] A connecting bearing 42 is fixedly connected to the side wall of the support plate 4. The connecting bearing 42 is sleeved on the outer wall of the drive screw 31. A lubricating sleeve 43 is fixedly connected to the side wall of the support plate 4 corresponding to the electric take-up roller 21. The lubricating sleeve 43 is sleeved on the outer wall of the vertical adjustment rope 2. The connecting bearing 42 and the lubricating sleeve 43 play a lubricating role.
[0024] One of the connecting plates 41 is fixedly connected to a controller 5 at its bottom end. The controller 5 is signal-connected to the electric take-up roller 21 and the drive motor 33. The controller 5 can control the opening and closing of the electric take-up roller 21 and the drive motor 33 to adjust the position of the C-shaped suspension support 1.
[0025] The working principle and usage process of this utility model are as follows: Workers tie the suspension wire 12 to the heavy material, securing it with multiple turns to improve stability. Then, the other end of the suspension wire 12 is tied with multiple turns to the outer wall of the two binding support rods 11. Subsequently, the electric winding roller 21 winds up the vertical adjusting rope 2, lifting the C-shaped suspension support 1 upwards. This, in turn, lifts the heavy material via the suspension wire 12. Then, the drive motor 33 drives the drive screw 31 to rotate, causing the screw thread sleeve 3 to move laterally along the drive screw 31, thus lifting the heavy material. As the material moves to the top of the steelmaking furnace filling inlet, the electric winding roller 21 simultaneously winds up the vertical adjustment rope 2 to keep the U-shaped suspension support 1 at a suitable height. Then, the electric winding roller 21 gradually releases the vertical adjustment rope 2, and the heavy object slowly falls under gravity until the heavy material touches the bottom and contacts the steelmaking furnace. During this process, the suspension wire 12 extends into the molten steel in the steelmaking furnace and is melted after a certain period of time. If the suspension wire 12 is not melted after the heavy material filling is completed, the workers use wire cutters to cut the suspension wire 12.
