Description

Technical Field

[0001] This utility model belongs to the technical field of electric arc furnace smoke hoods, and in particular relates to a sliding rail lifting electric arc furnace smoke hood. Background Technology

[0002] Submerged arc furnaces are widely used in the metallurgical industry for the production of ferroalloys and chemical raw materials such as calcium carbide. The fume hood of a submerged arc furnace is a key component of the system, primarily used for flue gas collection, waste heat recovery, and environmental protection. During the production of ferroalloys, the volume of flue gas generated during the iron removal process is large, with numerous flames and high temperatures. Under prolonged high-temperature baking, the fume hood at the taphole is prone to thermal stress deformation and collapse, posing a serious safety hazard. Current submerged arc furnace fume hoods are typically assembled using separate cover plates. Because the fume hood is constantly exposed to the high-temperature environment of the furnace, the cover plate near the taphole needs to be replaced periodically. Traditional replacement methods involve welding lifting lugs to the cover plate to be replaced and then using a hand-operated hoist for movement and replacement. This method has disadvantages such as long replacement cycles, high labor intensity, and low work efficiency. Furthermore, the submerged arc furnace consists of multiple furnace holes, resulting in a huge workload for replacing the fume hood cover plates. Therefore, there is an urgent need for a submerged arc furnace fume hood that is easy to maintain, safe, and efficient. Utility Model Content

[0003] This utility model provides a hydraulic brake cylinder with electrode combination for a submerged arc furnace to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sliding rail lifting type electric arc furnace fume hood includes a fume hood body. A square groove adapted to a cover plate is opened in the middle of the fume hood body. Two parallel moving grooves are opened on both sides of the square groove on the top surface of the fume hood body. A support plate is slidably installed in the moving groove. An elongated groove is opened on the opposite side of the support plate. It also includes a connecting frame. Moving frames are fixed on both sides of the connecting frame and are slidably fitted in the elongated groove. A driving component for driving the connecting frame to slide along the elongated groove is provided on the top of the connecting frame. Two C-shaped rotating rods are connected to each of the left and right sides of the connecting frame. The other end of the C-shaped rotating rods is connected to a placement frame for fixing the cover plate.

[0006] Furthermore, two C-shaped rotating rods located on the rear side are fixedly equipped with sliding rods, and an L-shaped groove is opened on the lower side of the support plate for the sliding rods to slide in, with the sliding rods slidingly engaged in the L-shaped grooves.

[0007] Furthermore, the drive assembly includes a rack mounted on the top of the connecting frame and a motor mounted on the top of the support plate, with a gear meshing with the rack on the motor output shaft.

[0008] Furthermore, the C-shaped rotating rod includes a first rotating rod, a second rotating rod, and a third rotating rod. The two ends of the second rotating rod are respectively hinged to the first rotating rod and the third rotating rod. The other end of the first rotating rod is connected to the side of the connecting frame, and the other end of the third rotating rod is connected to the side of the placement frame. The sliding rod is fixedly disposed on the outer surface of the end of the third rotating rod connected to the placement frame.

[0009] Furthermore, each of the two side walls of the placement frame has two rectangular slots, and an L-shaped plate is rotatably installed in the rectangular slots. A C-shaped rod is movably inserted into the L-shaped plate, and a fixing block is installed at the end of the C-shaped rod. A first compression spring is fixedly provided on the side of the fixing block, and the other end of the first compression spring abuts against the vertical plate of the L-shaped plate.

[0010] Furthermore, the top of the horizontal plate of the L-shaped plate has a beveled angle structure.

[0011] Furthermore, a movable wheel is rotatably mounted inside the movable frame, making rolling contact with the inner wall of the long groove.

[0012] Furthermore, a sliding groove is provided on the rear side of the support plate, and an L-shaped locking block is provided in the sliding groove. A second compression spring is provided on the top of the horizontal plate of the L-shaped locking block, and the L-shaped locking block is elastically installed in the sliding groove by the second compression spring.

[0013] Furthermore, the movable slot has several slots inside, and the vertical block of the L-shaped card block engages with the slots.

[0014] Furthermore, the left and right sides of the support plate are rounded, and a protective cover is provided on the outside of the gear on the support plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model achieves rapid positioning and replacement of the cover plate through the slide rail lifting mechanism of the drive component, which improves replacement efficiency and reduces the labor intensity and safety risks of workers.

[0017] 2. Through the cooperation of the slide bar and the L-shaped groove, as the drive component moves the connecting block, the slide bar slides in the L-shaped groove to guide the C-shaped rotating rod to rotate relative to each other, thereby realizing the lifting and lowering of the placement frame.

[0018] 3. The drive assembly adopts a rack and pinion transmission method. The motor drives the gear to rotate, the gear drives the rack to move, and then drives the connecting frame to move horizontally along the long slot.

[0019] 4. The L-shaped plate, which is rotatably installed in the rectangular groove of the placement frame, forms a reliable cover plate fixing assembly through the movable C-shaped rod and the fixing block, and is supplemented by the first compression spring. The deflection of the L-shaped plate and the clamping of the fixing block can firmly lock the cover plate and prevent it from moving or falling off due to vibration or thermal stress during use.

[0020] 5. The top of the horizontal plate of the L-shaped plate adopts a beveled angle structure, which allows the L-shaped plate to better fit the side of the cover plate when it is deflected or subjected to force, providing more stable and reliable support, avoiding support failure caused by the cover plate shaking, and improving the stability of the cover plate installation.

[0021] 6. The moving frame is equipped with moving wheels that roll in contact with the inner wall of the long groove, which reduces the frictional resistance between the moving frame and the long groove, making the horizontal movement of the connecting frame smoother.

[0022] 7. An L-shaped locking block is provided in the sliding groove on the rear side of the support plate, and is elastically installed by the second compression spring, which facilitates flexible adjustment of the position of the support plate and reliable locking. The slot opened inside the moving groove cooperates with the vertical block of the L-shaped locking block. By inserting and engaging the L-shaped locking block in the slot, the support plate is firmly fixed in a specific position of the moving groove.

[0023] 8. The rounded corners on both sides of the support plate eliminate sharp edges and corners, preventing accidental scratches to operators when they come into contact with the support plate and improving the safety of the equipment during operation. The protective cover on the outside of the gears on the support plate effectively isolates external environmental factors such as dust and high-temperature fumes from damaging the motor and gears and other precision transmission components, thus extending the service life of the equipment.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-7 As shown, a sliding rail lifting type electric arc furnace fume hood includes a fume hood body 1. A square groove 101 adapted to a cover plate is formed in the middle of the fume hood body 1. Two parallel moving grooves 2 are formed on both sides of the square groove 101 on the top surface of the fume hood body 1. A support plate 3 is slidably installed in the moving grooves 2. An elongated groove 4 is formed on the opposite side of the support plate 3. A connecting frame 5 is also included. Moving frames 6 are fixed on both sides of the connecting frame 5 and slidably fitted within the elongated grooves 4. A driving component for driving the connecting frame 5 to slide along the elongated grooves 4 is provided at the top of the connecting frame 5. Two C-shaped rotating rods 8 are connected to each of the left and right sides of the connecting frame 5. The other end of each C-shaped rotating rod 8 is connected to a placement frame 901 for fixing the cover plate. Sliding rods 801 are fixedly installed on the two C-shaped rotating rods 8 located at the rear. An L-shaped groove 12 for sliding the sliding rods 801 is formed on the lower side of the support plate 3, and the sliding rods 801 slidably fit within the L-shaped groove 12.

[0034] The drive assembly includes a rack 701 mounted on the top of the connecting frame 5 and a motor 703 mounted on the top of the support plate 3. The output shaft of the motor 703 is equipped with a gear 704 that meshes with the rack 701. The motor 703 drives the rack 701 to move through the gear 704, thereby driving the connecting frame 5 to move along the long slot 4.

[0035] The C-shaped rotating rod 8 includes a first rotating rod 802, a second rotating rod 803, and a third rotating rod 804. The two ends of the second rotating rod 803 are hinged to the first rotating rod 802 and the third rotating rod 804, respectively. The other end of the first rotating rod 802 is connected to the side of the connecting frame 5, and the other end of the third rotating rod 804 is connected to the side of the placement frame 901. A sliding rod 801 is fixedly mounted on the outer surface of the end of the third rotating rod 804 connected to the placement frame 901. The structural design of the C-shaped rotating rod 8 allows the sliding rod 801 to slide in the L-shaped groove 12, and through hinged linkage, control the lifting and lowering of the placement frame 901, thereby realizing the up-and-down movement of the cover plate.

[0036] The placement frame 901 has two rectangular slots 902 on each of its two side walls. An L-shaped plate 903 is rotatably installed in the rectangular slot 902. A C-shaped rod 904 is movably inserted into the L-shaped plate 903. A fixing block 905 is installed at the end of the C-shaped rod 904. A first compression spring 906 is fixedly installed on the side of the fixing block 905. The other end of the first compression spring 906 abuts against the vertical plate of the L-shaped plate 903. The bottom of the fixing block 905 directly contacts the top of the cover plate, providing vertical limiting to prevent the cover plate from moving after being clamped.

[0037] The top of the L-shaped plate 903 has a beveled angle. This beveled angle allows the L-shaped plate 903 to better fit the side of the cover plate when it deflects, providing more stable support and preventing support failure due to unevenness or slight shaking of the cover plate surface. A moving wheel 601 is rotatably mounted inside the moving frame 6, making rolling contact with the inner wall of the long groove 4. Rolling friction replaces sliding friction, reducing the friction between the moving frame 6 and the long groove 4, making the movement of the connecting frame 5 smoother.

[0038] A sliding groove 10 is provided on the rear side of the support plate 3. An L-shaped locking block 11 is provided in the sliding groove 10. A second compression spring 1101 is provided on the top of the horizontal plate of the L-shaped locking block 11. The L-shaped locking block 11 is elastically installed in the sliding groove 10 by the second compression spring 1101. Several slots 201 are provided inside the moving groove 2. The vertical block of the L-shaped locking block 11 engages with the slot 201. By moving the vertical block of the L-shaped locking block 11 into the slots 201 on the inner wall of different moving grooves 2 and using the elastic action of the second compression spring 1101 to engage it, the support plate 3 can be fixed, thereby enabling the replacement of the cover plate at different positions on the upper side of the smoke hood body 1.

[0039] The support plate 3 has rounded corners on both sides. The rounded corner design eliminates sharp edges and corners, preventing accidental scratches to operators when they come into contact with the support plate 3, thus improving operational safety. A protective cover 301 is provided on the outside of the gear 704 on the support plate 3. The protective cover 301 can effectively shield key transmission components such as the motor 703 and gear 704, preventing the intrusion of external dust, high-temperature fumes or other debris, avoiding damage to these precision components, thereby extending the service life of the equipment and ensuring the stable operation of the transmission system.

[0040] When using this utility model, firstly, the cover plate to be replaced is placed inside the placement frame 901. Then, the cover plate's own weight causes the four L-shaped plates 903 to deflect downwards, so that the bottom of the horizontal plate of the L-shaped plate 903 moves to contact the bottom of the inner wall of the rectangular groove 902. At the same time, the top of the horizontal plate of the L-shaped plate 903 supports the cover plate. After the cover plate is fixed inside the placement frame 901, the C-shaped rod 904, through the rebound force of the first compression spring 906, drives the two fixed blocks 905 as a group to close in the middle at the same time. Then, the bottom of the fixed block 905 fixes the top of the cover plate, reducing the shaking of the cover plate due to heat and smoke. Next, the locking block 11 is moved upwards to compress the second compression spring 1101, so that the vertical block of the L-shaped locking block 11 moves out from inside the moving groove 2, releasing the fixed state between the support plate 3 and the moving groove 2. Then, the cover plates of different areas on the upper side of the smoke collection hood body 1 can be replaced. Next, the rotating shaft of motor 703 drives two gears 704 to rotate, causing two racks 701 to move. The connecting frame 5 drives the C-shaped rotating rod 8 and the placement frame 901 to move horizontally. At this time, the two sliding rods 801 slide inside the L-shaped groove 12. When the sliding rods 801 move to the inside of the vertical groove of the L-shaped groove 12, the C-shaped rotating rod 8 deflects, causing the placement frame 901 to move downward, thereby driving the cover plate inside it to move quickly to the top of the square groove 101 on the upper side of the smoke hood body 1, quickly replacing and fixing the cover plate, thereby reducing the workload of replacing the smoke hood cover plate and reducing the safety risks borne by the staff.

[0041] When the cover plate needs to be removed, the motor 703 rotates in reverse, causing the connecting frame 5 to move the placement frame 901 horizontally. The rotation of the C-shaped rotating rod 8 causes the placement frame 901 to rise. The operator applies a downward force to the two C-shaped rods 904, causing the two L-shaped plates 903 (as a group) to deflect upwards simultaneously, pushing the cover plate upwards to meet the smoke hood. This allows for quick separation of the cover plate from the smoke hood, enabling its disassembly and removal. This invention, through a motor-driven sliding rail lifting mechanism, achieves rapid cover plate replacement, significantly improving efficiency, reducing labor intensity and safety risks. It also features a simple structure and convenient maintenance. Furthermore, the optimized design of each component enhances the stability and safety of the entire device, providing a reliable guarantee for the production of the submerged arc furnace. Therefore, this device is practical.
