Description

Technical Field

[0001] This utility model relates to the field of electric furnace charging cart technology, and in particular to a rotatable charging cart for electric furnace charging. Background Technology

[0002] In industrial production such as metallurgy and chemical industry, electric furnace charging cars are an important auxiliary equipment. During electric furnace production, raw materials such as ore, scrap steel, and alloys need to be continuously added into the furnace. The charging car can load a large amount of material at once through its on-board hopper and quickly transport it to the electric furnace. Compared with manual handling or traditional transportation methods, it greatly shortens the charging time and improves the production pace.

[0003] When the feed inlets of equipment such as electric furnaces and reactors are distributed at different angles, or when multiple pieces of equipment in the workshop are arranged in a ring or irregular layout, a rotating feeding cart is used. By rotating the hopper or the whole cart 360°, the material can be directly aligned with the target position without moving the cart body. This avoids the inefficient operation of traditional fixed-direction feeding carts that require repeated repositioning, and is especially suitable for production scenarios with compact space or multiple pieces of equipment working together.

[0004] Considering that the size and shape of the hopper discharge opening of most feeding cart equipment are fixed, when facing a small-diameter feed inlet, the opening may be too large, causing material to tip over and spill, resulting in material waste; while for a large-diameter feed inlet, it is impossible to achieve fast and efficient filling, affecting the production progress. Therefore, a rotating feeding cart for electric furnace feeding is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotatable feeding cart for electric furnace charging, aiming to solve the problem that the size and shape of the hopper discharge opening of most existing feeding cart equipment are fixed, resulting in significant defects when adapting to the electric furnace inlet. With small-diameter inlets, an excessively large opening easily leads to material spillage and waste; while with large-diameter inlets, it is impossible to fill material quickly and efficiently, seriously affecting production progress.

[0032] 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.

[0033] Reference Figure 1 , Figures 3-4This utility model provides an embodiment of a rotatable charging cart for electric furnace charging, comprising a base 1. The base 1 serves as the basic support component of the entire charging cart, stably supporting the hopper 2 and other related components, providing a stable support platform for the operation of the entire charging cart, ensuring that the charging cart will not easily shake or tip over during operation. The hopper 2 is hinged to the top of the outer surface of the base 1, connecting the base 1 and the hopper 2 through a hinge, allowing the hopper 2 to rotate relative to the base 1. This rotatable connection design facilitates the adjustment of the angle of the hopper 2 to adapt to the electric furnace inlet at different positions and heights, improving the flexibility and convenience of charging. A guide plate 3 is hinged to the left side of the outer surface of the hopper 2, and the guide plate 3 can rotate around the hinge point. The rotation mechanism is used to adjust the flow direction during the feeding process according to actual needs, guiding the material accurately into the electric furnace, preventing material spillage, and improving feeding accuracy. A hinged rod 4 is hinged to the outer surface of the flow plate 3, and a traction frame 5 is hinged to the outer surface of the hinged rod 4. The hinged rod 4 is hinged to the flow plate 3 to transmit power. When the traction frame 5 moves, it drives the flow plate 3 to rotate through the hinged rod 4, thereby adjusting the angle of the flow plate 3 and controlling the flow direction and range of the material. The outer surface of the traction frame 5 is slidably connected to the bottom of the outer surface of the hopper 2, ensuring that the traction frame 5 can move smoothly laterally at the bottom of the outer surface of the hopper 2. This makes the movement of the traction frame 5 more smooth when driving the hinged rod 4 and the flow plate 3, preventing jamming.

[0034] Reference Figures 3-5 A threaded sleeve 9 is fixedly connected to the bottom of the outer surface of the traction frame 5. A threaded rod 10 is threadedly connected to the inner surface of the threaded sleeve 9. The threaded sleeve 9 is fixed on the traction frame 5 and works in conjunction with the threaded rod 10. By rotating the threaded rod 10, the rotational motion of the threaded rod 10 is converted into the linear motion of the traction frame 5 using the principle of thread transmission, thereby achieving precise control of the position of the traction frame 5. The outer surface of the threaded rod 10 is rotatably connected to the bottom of the inner surface of the hopper 2, allowing the threaded rod 10 to rotate freely within the hopper 2. At the same time, the stability of the threaded rod 10 during rotation is ensured, ensuring that it can reliably transmit power to the threaded sleeve 9 and the traction frame 5. An anti-accidental contact component 11 is provided on the right side of the outer surface of the threaded rod 10. The anti-accidental contact component 11 provides rotational power to the threaded rod 10 and prevents accidental operation.

[0035] Reference Figure 5The anti-accidental touch component 11 includes a turntable 111. The outer surface of the turntable 111 is fixedly connected to the right side of the outer surface of the threaded rod 10. Through the fixed connection between the turntable 111 and the threaded rod 10, the rotational power applied by the handle 112 can be transmitted to the threaded rod 10. The handle 112 is hinged to the right side of the inner surface of the turntable 111. The handle 112 is hinged to the turntable 111, which makes it convenient for the operator to drive the turntable 111 and the threaded rod 10 to rotate by shaking the handle 112, thereby adjusting the angle of the diversion plate 3. The hinged design allows the handle 112 to be retracted when not in use, reducing the space occupied and avoiding accidental operation caused by accidental touch.

[0036] Reference Figure 5 The anti-accidental touch component 11 also includes a limiting bolt 114. The outer surface of the limiting bolt 114 penetrates and is threadedly connected to the top of the inner surface of the turntable 111. The limiting bolt 114 is threadedly connected to the turntable 111 to fix the handle 112. When the handle 112 is adjusted to a suitable position, the handle 112 can be fixed by tightening the limiting bolt 114. A limiting hole 113 is opened at the top of the outer surface of the handle 112. The bottom of the outer surface of the limiting bolt 114 is inserted into the inner surface of the limiting hole 113. The limiting hole 113 and the limiting bolt 114 are used in conjunction. When the limiting bolt 114 is inserted into the limiting hole 113, it can effectively limit the rotation of the handle 112, ensure that the handle 112 remains fixed in the set position, and improve the reliability of the anti-accidental touch.

[0037] Reference Figure 1 , Figures 3-4 A sector plate 6 is fixedly connected to the left side of the outer surface of the hopper 2. The sector plate 6 is fixed to the left side of the hopper 2 to provide guidance and support for the rotation of the diversion plate 3. Its sector shape allows the diversion plate 3 to move along a specific trajectory during rotation, ensuring the stability and accuracy of the rotation of the diversion plate 3. It also helps to control the flow range of the material. The bottom end of the outer surface of the diversion plate 3 is slidably connected to the top end of the outer surface of the sector plate 6, so that the diversion plate 3 can slide smoothly along the surface of the sector plate 6 when rotating around the hinge point, further improving the smoothness and stability of the rotation of the diversion plate 3, and ensuring that the material can flow in the expected direction and range. A limit frame 8 is fixedly connected to the left side of the outer surface of the hopper 2. The top end of the outer surface of the traction frame 5 is slidably connected to the inner surface of the limit frame 8. The limit frame 8 is used to limit the movement range of the traction frame 5, prevent the traction frame 5 from deviating from the predetermined track during movement, ensure the movement accuracy of the traction frame 5, and thus ensure the accuracy of the angle adjustment of the diversion plate 3.

[0038] Reference Figure 2 , Figure 5A telescopic motor 7 is hinged to the right side of the outer surface of the base 1. The top of the outer surface of the telescopic motor 7 is hinged to the right side of the outer surface of the hopper 2. The telescopic motor 7 is hinged to the base 1 and can provide power for the rotation of the hopper 2. Through the telescopic movement of the telescopic motor 7, the hopper 2 is driven to rotate around the hinge point with the base 1, so as to adjust the angle of the hopper 2 to adapt to the position and height of the feed port of different electric furnaces. A limit member 115 is fixedly connected to the bottom of the outer surface of the turntable 111. The bottom of the outer surface of the handle 112 is in contact with the top of the outer surface of the limit member 115. The limit member 115 is fixed to the bottom of the turntable 111 and is used to limit the rotation angle of the handle 112. When the handle 112 rotates to a certain angle, the limit member 115 will contact the handle 112 to prevent the handle 112 from rotating excessively and protect the relevant components.

[0039] Reference Figures 1-2 Two sets of guide plates 3 are symmetrically arranged on the left side of the outer surface of the hopper 2. The two sets of symmetrically arranged guide plates 3 can more effectively control the flow direction and range of materials. By adjusting the angle of the two sets of guide plates 3 at the same time, the size and shape of the feeding port can be precisely adjusted to better adapt to the needs of different electric furnace feeding ports and improve the efficiency and accuracy of feeding. Two sets of telescopic motors 7 are symmetrically arranged on the right side of the outer surface of the hopper 2. The two sets of symmetrically arranged telescopic motors 7 can provide more stable and balanced power for the rotation of the hopper 2, ensuring that the hopper 2 is more stable during rotation and avoiding tilting or shaking, thus improving the accuracy and reliability of the angle adjustment of the hopper 2.

[0040] Working principle: When feeding electric furnaces with different feed inlet sizes, first unscrew the limiting bolt 114 to release the fixation of the handle 112. Then, flip the handle 112 outward and shake it to make it rotate the turntable 111, which in turn rotates the threaded rod 10. When the threaded rod 10 rotates, it will be connected to the threaded sleeve 9, which will cause the traction frame 5 to move laterally along the left side of the outer surface of the hopper 2. When the traction frame 5 moves laterally, it will simultaneously drive the two sets of hinged rods 4 to move, and simultaneously drive the two sets of diversion plates 3 to flip along the top of the fan-shaped plate 6 on the left side of the hopper 2, thereby adjusting the opening size of the feed inlet of the hopper 2 to adapt to the effect of different electric furnace feed inlets.
