Description

Technical Field

[0001] This utility model relates to the field of electric furnace smelting technology, and in particular to a visualization device for an electric furnace EBT tapping locking mechanism. Background Technology

[0002] The EBT tapping locking mechanism is a locking device used in the electric arc furnace smelting process to control the tapping of molten steel. The function of this device is to ensure the sealing of the tapping port and the precise control of the molten steel flow, so as to avoid molten steel leakage, pollution and other possible safety hazards, thereby improving the safety and efficiency of the smelting process.

[0003] In the electric arc furnace steelmaking process, the locking mechanism driven by the EBT locking cylinder is responsible for controlling the opening and closing safety interlock of the EBT tray mechanism to ensure the smooth tapping of molten steel and the safe locking of the furnace bottom. However, since the locking cylinder is located in a sealed box, operators can only judge whether the cylinder has moved by the sound of its movement. This results in problems such as inaccurate monitoring, slow response, and difficulty in visually displaying the cylinder's movement status. These problems may lead to safety hazards in the production process and even cause serious accidents. At the same time, the operation is relatively complicated and inefficient when repairing or replacing the electric arc furnace. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a visualization device for the EBT tapping locking mechanism of an electric furnace.

[0005] This utility model is achieved using the following technical solution: a visual device for an electric arc furnace (EBT) tapping locking mechanism, comprising a housing, a baffle fixedly connected inside the housing, a rotating groove formed inside the baffle, and a graduated dial fixedly connected to the front of the housing, characterized in that it further comprises:

[0006] A locking visual mechanism includes a second rotating column rotatably connected inside the housing, a connecting block fixedly connected to the outside of the second rotating column, and a locking cylinder provided inside the housing.

[0007] The disassembly and assembly mechanism includes a connecting plate fixedly connected to the top of the connecting block, and an electric furnace is provided on the top of the connecting plate.

[0008] As a further improvement to the above solution, a first rotating column is fixedly connected inside the outer shell, a rotating plate is rotatably connected to the outside of the first rotating column, and a locking cylinder is fixedly connected to the left side of the rotating plate.

[0009] Through the above technical solution, the connection structure between the first rotating column, the rotating plate and the locking cylinder enhances the stability and reliability of the locking cylinder, avoids unstable movement of the connecting block and the electric furnace caused by cylinder shaking, thereby ensuring the accuracy and efficiency of the steel tapping process and helping to improve the overall production efficiency of electric furnace smelting.

[0010] As a further improvement to the above solution, a rotating block is fixedly connected to the left end of the locking cylinder, a pointing rod is fixedly connected to the outside of the second rotating column, and the rotating block is rotatably connected inside the connecting block.

[0011] Through the above technical solution, the rotational connection between the rotating block and the connecting block enables the movement of the locking cylinder to be effectively converted into the tilting movement of the electric furnace, ensuring the accurate execution of the steel tapping action. At the same time, the cooperation between the pointing rod and the dial allows the operator to understand the tilting angle of the electric furnace and the movement trajectory of the locking cylinder in real time, improving the accuracy and safety of the operation.

[0012] As a further improvement to the above solution, a fixing block is fixedly connected to the top of the connecting plate, and a servo motor is fixedly connected to the front of the connecting plate.

[0013] Through the above technical solution, the insert block can be easily detached from the mounting plate by means of the servo motor and threaded rod, which makes the disassembly and installation of the equipment more convenient. This design greatly improves the maintenance efficiency of the electric furnace equipment, reduces the downtime of the equipment, and helps to improve the reliability and service life of the electric furnace.

[0014] As a further improvement to the above solution, the output end of the servo motor is fixedly connected to a threaded rod, and a moving block is connected to the external thread of the threaded rod.

[0015] The above technical solution enables the moving block to slide smoothly. This design, through precise control of the insertion and removal of the plug, ensures that the fixing and disassembly of the electric furnace and other components is safer and more accurate, thereby optimizing the working stability of the equipment.

[0016] As a further improvement to the above solution, a plug block is fixedly connected to the top of the movable block, and an installation plate is fixedly connected to the bottom of the electric furnace.

[0017] Through the above technical solution, the sliding block and the working of the moving block enable the electric furnace to be installed and disassembled more smoothly, further enhancing the convenience and operability of assembly and disassembly.

[0018] As a further improvement to the above solution, two movable blocks are provided, and the two movable blocks are respectively threadedly connected to the outside of the threaded rod in different thread directions.

[0019] By using the above technical solution, two moving blocks are set up to move along different thread directions, which improves the accuracy and flexibility required for the disassembly and assembly of the equipment, ensures the synchronous and coordinated work of each part, and improves the operating efficiency.

[0020] As a further improvement to the above solution, the insert block is slidably connected inside the fixed block, and the mounting plate is sleeved on the outside of the fixed block.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention achieves visualized monitoring of the steel tapping process by retracting the locking cylinder during the tapping process. This retraction causes the connecting block to rotate around the second rotating column via a rotating block, tilting the electric furnace to pour out molten steel. Simultaneously, the guide rod on the outside of the second rotating column moves synchronously with the rotation, and the scale on the front of the outer shell provides a reference for observation. Operators can clearly understand the movement trajectory of the locking cylinder and the tilt angle of the electric furnace, thereby more accurately controlling the rhythm and force of the tapping, ensuring the accuracy and efficiency of the tapping process, and helping to improve the overall production efficiency of electric furnace smelting.

[0023] This invention utilizes a servo motor to drive a threaded rod to rotate clockwise, causing the insert block to detach from the mounting plate for easy removal. During installation, the electric furnace is placed over the fixed block, and the servo motor rotates counterclockwise, causing the threaded rod to rotate counterclockwise as well. This causes the moving block to slide outward from the fixed block, allowing the insert block to be inserted into the mounting plate for secure installation. This method facilitates the easy assembly and disassembly of the electric furnace. The process is simple, convenient, and quick, effectively improving equipment maintenance efficiency, reducing downtime, lowering maintenance costs and complexity, and enhancing equipment reliability and lifespan.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Example:

[0033] Please combine Figure 1-5 This embodiment of an electric arc furnace (EBT) tapping locking mechanism visualization device includes a housing 1, a baffle 11 fixedly connected inside the housing 1, a rotating groove 12 formed inside the baffle 11, and a scale 13 fixedly connected to the front of the housing 1. It also includes:

[0034] The locking visual mechanism 2 includes a second rotating column 205 rotatably connected inside the housing 1, a connecting block 206 fixedly connected to the outside of the second rotating column 205, and a locking cylinder 203 provided inside the housing 1.

[0035] The disassembly and assembly mechanism 3 includes a connecting plate 301 fixedly connected to the top of the connecting block 206, and an electric furnace 308 is provided on the top of the connecting plate 301.

[0036] The outer casing 1 is fixedly connected to a first rotating column 201, and the outer side of the first rotating column 201 is rotatably connected to a rotating plate 202. A locking cylinder 203 is fixedly connected to the left side of the rotating plate 202.

[0037] A rotating block 204 is fixedly connected to the left end of the locking cylinder 203, and a pointing rod 207 is fixedly connected to the outside of the second rotating column 205. The rotating block 204 is rotatably connected inside the connecting block 206.

[0038] A fixing block 302 is fixedly connected to the top of the connecting plate 301, and a servo motor 303 is fixedly connected to the front of the connecting plate 301.

[0039] The output end of the servo motor 303 is fixedly connected to a threaded rod 304, and the threaded rod 304 is externally threaded to a moving block 305.

[0040] The top of the movable block 305 is fixedly connected to the insert block 306, and the bottom of the electric furnace 308 is fixedly connected to the mounting plate 307.

[0041] There are two movable blocks 305, which are threadedly connected to the outside of the threaded rod 304 in different thread directions.

[0042] The insert block 306 is slidably connected inside the fixing block 302, and the mounting plate 307 is sleeved on the outside of the fixing block 302.

[0043] The implementation principle of the visualization device for the EBT tapping locking mechanism in this application embodiment is as follows: When it is necessary to tap the molten steel inside the electric furnace 308, the locking cylinder 203 is first activated. After receiving the command, the locking cylinder 203 begins to retract. Since the left end of the locking cylinder 203 is fixedly connected to the rotating block 204, and the rotating block 204 is rotatably connected inside the connecting block 206, while the connecting block 206 is fixedly connected outside the second rotating column 205, the retraction of the locking cylinder 203 will drive the connecting block 206 to rotate around the second rotating column 205 through the rotating block 204.

[0044] As the connecting block 206 rotates, the electric furnace 308 on top of it will also tilt, thereby pouring out the molten steel inside the electric furnace 308. During this process, the pointing rod 207 fixedly connected to the outside of the second rotating column 205 will rotate synchronously with the rotation of the second rotating column 205. Since the front of the outer shell 1 is fixedly connected to the scale 13, by observing the position change of the pointing rod 207 on the scale 13, the movement trajectory of the locking cylinder 203 and the tilt angle of the electric furnace 308 can be clearly understood, realizing the visual monitoring of the steel tapping process.

[0045] When the electric furnace 308 needs to be repaired or replaced, the servo motor 303 is started. The output end of the servo motor 303 is fixedly connected to the threaded rod 304. When the servo motor 303 drives the threaded rod 304 to rotate clockwise, the moving block 305 connected to the external thread of the threaded rod 304 will move into the interior of the fixed block 302 under the action of the thread.

[0046] The movement of the movable block 305 will cause the insert block 306 to move into the fixed block 302. At this time, the mounting plate 307 fixedly connected to the bottom of the electric furnace 308 is sleeved on the outside of the fixed block 302. As the insert block 306 moves, the insert block 306 will gradually detach from the mounting plate 307, thereby releasing the fixation of the electric furnace 308. When the insert block 306 is completely detached from the mounting plate 307, the electric furnace 308 can be easily pulled out of the device for subsequent maintenance or replacement work.

[0047] After repairing or replacing the electric furnace 308, installation is required. First, place the repaired or new electric furnace 308 over the fixed block 302, aligning the mounting plate 307 at the bottom of the electric furnace 308 with the fixed block 302. Then, start the servo motor 303 to rotate counterclockwise, causing the threaded rod 304 to rotate counterclockwise. During the counterclockwise rotation of the threaded rod 304, the moving block 305 will slide outward from the fixed block 302 under the action of the thread, and drive the insert block 306 to move outward from the fixed block 302. When the insert block 306 is inserted into the mounting plate 307, the mounting plate 307 is fixed, thus firmly installing the electric furnace 308 on the device.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
