Description

Technical Field

[0001] This invention relates to the field of mechanical metallurgical equipment technology, specifically to a welding slag pot for long-distance transportation and dumping of smelting slag. Background Technology

[0002] In the metallurgical production process, after the smelting process is completed, the remaining molten steel or slag in the furnace needs to be discharged into a special slag pot. It is then transported to a designated tipping position by a ladle car or bridge crane. Operators manually hook the tipping hook onto the trunnions on both sides of the bottom of the slag pot, and then connect it to the gantry crane hook through the lifting chain. Subsequently, the crane slowly lifts the slag pot to achieve a controlled tipping, with the tipping angle usually being 90-120°, so as to safely discharge the high-temperature molten slag in the pot.

[0003] A search revealed a Chinese patent with patent number CN222631469U, which discloses an automatic tilting system for slag hoppers. By setting up a slag truck, a trolley, a tilting device, and a control mechanism, the slag truck transports the slag hopper to the trolley, the trolley transports the slag hopper to a designated location in the tilting device, and the tilting device automatically tilts the slag hopper. The entire slag dumping process can be completed automatically, reducing manual operation or achieving unmanned operation on site, and improving work efficiency.

[0004] However, in actual use, after the slag pot containing the molten slag is transported over a long distance, the surface of the slag pot loses heat, causing the molten slag to gradually cool and solidify from the outside to the inside. As a result, a scale layer is easily formed on the inner wall surface of the slag pot, which reduces the effective volume of the slag pot when it is used again. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a welding slag container for long-distance transportation and dumping of smelting slag. This effectively solves the problem in existing technologies where, after long-distance transportation, the surface of the slag container dissipates heat, causing the slag to gradually cool and solidify from the outside in. This results in the formation of a scale layer on the inner wall of the slag container, leading to a reduction in the effective volume of the slag container for subsequent use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a welding slag pot for long-distance transportation and dumping of smelting slag, comprising a support and a slag pot body. The support has a discharge groove on its surface, and a rotating groove at the inner end of the discharge groove. A cylinder for driving a movable seat is rotatably mounted on the inner wall of the support. The invention also includes: The tilting mechanism includes a movable seat that is slidably mounted on a bracket and connected to the output end of a cylinder. The movable seat has an installation groove on its surface for supporting the slag pot body. A driven rack that extends into the installation groove and restricts the rotation of the slag pot body shaft is slidably mounted inside the slag pot body. The striking mechanism includes a sliding rod that is slidably mounted on a support and can move toward the slag pot body. A turntable is provided below the sliding rod and is rotatably mounted inside the support. The surface of the turntable is eccentrically provided with protrusions for driving the sliding rod toward and away from the slag pot body.

[0007] Furthermore, the bottom of the movable seat is provided with a limiting shaft, and a snap-fit ​​block is provided at one end of the limiting shaft near the lead-out groove. A rotating shaft is rotatably installed inside the rotating groove, and a snap-fit ​​groove matching the snap-fit ​​block is opened on the surface of the rotating shaft near the limiting shaft.

[0008] Furthermore, the support surface is provided with a tilting groove, which is composed of a horizontal straight section and an arc-shaped section. The outlet groove is straight along the moving direction of the slag pot body. The tilting groove is located above the outlet groove, and the straight section of the tilting groove is parallel to the outlet groove.

[0009] Furthermore, the bottom of the movable seat is provided with a first support leg and a second support leg. The bottom of the first set of support legs is fixedly connected to the limiting shaft. The length of the first set of support legs is longer than the length of the second set of support legs. The second set of support legs is movably installed inside the flipping groove.

[0010] Furthermore, the inner wall of the bracket is provided with an active rack, and the movable seat is provided with a transmission gear that meshes with the active rack. The opposite side of the transmission gear is meshed with the driven rack. The movable seat is provided with a locking groove. The driven rack is slidably mounted on the movable seat and extends into the locking groove. The driven rack is parallel to the active rack. The movable seat is provided with a clearance groove on the side near the active rack. The clearance groove is used to prevent the movable seat from being restricted by the active rack when it moves.

[0011] Furthermore, the end of the sliding rod away from the protrusion is provided with a striking block for striking the outer wall of the slag pot body. The sliding rod has a T-shaped overall shape when viewed from above, and a limiting groove for the protrusion to slide is provided on the side of the sliding rod away from the striking block.

[0012] Furthermore, the support surface is provided with a guide groove for limiting the sliding rod, and the end of the rotating shaft away from the limiting shaft is provided with a driving gear. The driving gear is meshed with a driven gear, and the turntable is coaxially mounted with a connecting shaft. The driven gear and the connecting shaft are driven and connected by a bevel gear set.

[0013] Furthermore, the tilting mechanism and the striking mechanism are provided in two sets, and are symmetrically arranged with the vertical reference plane of the slag pot body as the symmetrical plane. The vertical reference plane is parallel to the vertical outer wall of the support.

[0014] Beneficial effects The technical solution provided by this invention, compared with known prior art: 1. Through the cooperation of the lead-out groove and the tilting groove, the moving seat remains stable during the translation stage. After entering the arc section of the tilting groove, it tilts and the rotation of the turntable is converted into the reciprocating linear striking action of the sliding rod through the cooperation of the turntable and the sliding rod, so as to realize the automatic removal of molten slag from the inner wall of the slag pot. Second, by adopting a meshing transmission structure of active rack, transmission gear and driven rack, the trunnion of the slag pot body is fixed in two stages. The movement of the moving seat enables the two sets of tilting mechanisms to clamp the trunnion from both sides at the same time, forming a two-way lock. This prevents the trunnion from loosening or misaligning due to insufficient fixation on one side when rotating, and ensures the stability of the slag pot body during transportation and tilting. Third, by using a combination of long and short support legs to form a rigid triangular frame, the center of gravity shifts during tipping, ensuring the overall stability of the slag container body during tipping, reducing the risk of tipping over, and thus further improving the stability of the slag container body during transportation and tipping.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] A welding slag container for long-distance transportation and dumping of smelting slag, see attached figure. Figures 1-10 The system includes a support 1 and a slag pot body 2. The support 1 has a discharge groove 101 on its surface and a rotating groove 103 at its inner end. A cylinder 5 for driving the movable seat 301 is rotatably mounted on the inner wall of the support 1. The system also includes: The tilting mechanism 3 includes a movable seat 301 that is slidably mounted on the bracket 1 and connected to the output end of the cylinder 5. The movable seat 301 has an installation groove 302 for supporting the slag pot body 2. A driven rack 306 that extends into the installation groove 302 and restricts the rotation of the shaft of the slag pot body 2 is slidably mounted inside the slag pot body 2. When the movable seat 301 rotates, 306 is released under the action of gravity and is limited and fixed. The slag pot body 2 is fixed through the limiting structure to ensure the stability of the slag pot body 2 during the tilting process. The striking mechanism 4 includes a sliding rod 408 that is slidably mounted on the support 1 and can move toward the slag pot body 2. A turntable 406 is provided below the sliding rod 408 and is rotatably mounted inside the support 1. The surface of the turntable 406 is eccentrically provided with protrusions 407 for driving the sliding rod 408 to approach and move away from the slag pot body 2. The rotation of the turntable 406 converts the circular motion into the reciprocating linear striking action of the sliding rod 408, thereby realizing the function of automatically removing the molten slag from the inner wall.

[0021] Furthermore, the bottom of the movable seat 301 is provided with a limiting shaft 307. The end of the limiting shaft 307 near the outlet groove 101 is provided with a snap-fit ​​block. The rotating shaft 308 is rotatably installed inside the rotating groove 103. The surface of the rotating shaft 308 near the limiting shaft 307 is provided with a snap-fit ​​groove that matches the snap-fit ​​block. When the movable seat 301 moves to the end of the outlet groove 101, the snap-fit ​​block of the limiting shaft 307 will be embedded in the snap-fit ​​groove of the rotating shaft 308, so that the two form a rigid connection, thereby converting the translational motion of the movable seat 301 into a rotational motion centered on the rotating shaft 308, ensuring the stability and accuracy of the slag pot body 2 when it is tilted.

[0022] Furthermore, a tilting groove 102 is provided on the surface of the support 1. The tilting groove 102 consists of a horizontal straight section and an arc section. The outlet groove 101 is straight along the moving direction of the slag pot body 2. The tilting groove 102 is located above the outlet groove 101, and the straight section of the tilting groove 102 is parallel to the outlet groove 101. The horizontal straight section of the tilting groove 102 extends parallel to the outlet groove 101 to ensure that the moving seat 301 remains stable during the translation phase. When the moving seat 301 moves to the end of the outlet groove 101, its second support foot just enters the arc section of the tilting groove 102, guiding the moving seat 301 to tilt smoothly around the rotation shaft 308. The double groove structure, through the cooperation of straight guidance and arc limiting, not only ensures the linear stability of the slag pot body 2 during transportation, but also realizes the precise control of the tilting action.

[0023] Furthermore, the bottom of the movable seat 301 is provided with a first support leg and a second support leg. The bottom of the first set of support legs is fixedly connected to the limiting shaft 307. The length of the first set of support legs is longer than that of the second set of support legs. The second set of support legs is movably installed inside the tilting groove 102. The first support leg serves as the main support arm during tilting, ensuring the stability of the arc motion trajectory centered on the rotation shaft 308. The second support leg is movably embedded in the tilting groove 102, providing auxiliary support when the movable seat 301 moves along the lead-out groove 101. After entering the arc section of the tilting groove 102, it works with the first support leg to form a double-point fixation, preventing the center of gravity from shifting during tilting. The combination of long and short support legs forms a triangular rigid frame, which significantly improves the overall stability of the slag pot body 2 during transportation, fixing and tilting.

[0024] Furthermore, the inner wall of the bracket 1 is provided with an active rack 105, and the movable seat 301 is provided with a transmission gear 305 that meshes with the active rack 105. The opposite side of the transmission gear 305 is meshed with the driven rack 306. The movable seat 301 has a locking groove 303 inside. The driven rack 306 is slidably mounted on the movable seat 301 and extends into the locking groove 303. The driven rack 306 is parallel to the active rack 105. The movable seat 301 has a relief groove 304 on the side near the active rack 105. The relief groove 304 is used to prevent the movable seat 301 from being restricted by the active rack 105 when it moves. The trunnion end of the slag pot body 2 is rectangular and fits perfectly with the mounting groove 302. The driven rack 306 has a certain thickness and the driven rack 306... The thickness of the rack 306 is the same as the height of the drive rack 303, and there is a certain height difference between the end of the driven rack 306 near the drive gear 305 and the end of the locking groove 303 that engages with it, so that the driven rack 306 can withstand the force generated when the slag pot body 2 is overturned. The clearance groove 304 is used to prevent the moving seat 301 from getting stuck during the sliding process. The drive gear 305 is rotatably mounted inside the moving seat 301 via a shaft. Specifically, when the drive gear 305 inside the moving seat 301 meshes with the drive rack 105, as the moving seat 301 moves forward, the drive gear 305 rotates through the meshing action with the drive rack 105, and through the meshing action with the driven rack 306, the driven rack 306 moves along the extension direction of the locking groove 303.

[0025] Furthermore, the end of the sliding rod 408 away from the protrusion 407 is provided with a striking block 410 for striking the outer wall of the slag pot body 2. The sliding rod 408 has a T-shaped overall shape when viewed from above, and a limiting groove 409 for the protrusion 407 to slide is provided on the side of the sliding rod 408 away from the striking block 410. 402 and 103 are rotatably installed inside 1. The striking block 410 is made of elastic material and has a buffer structure inside. Since the outer contour position of the slag pot body changes, the elastic material and the internal buffer structure can adaptively fine-tune the contact between the striking block 410 and the slag pot body 2, while avoiding the phenomenon of the protrusions 407 and 408 getting stuck, thereby maintaining effective striking.

[0026] Furthermore, the support 1 has a guide groove 104 on its surface for limiting the sliding rod 408. The end of the rotating shaft 308 away from the limiting shaft 307 is provided with a drive gear 402. The drive gear 402 is meshed with a driven gear 403. The turntable 406 is coaxially mounted with a connecting shaft 405. The driven gear 403 and the connecting shaft 405 are driven and connected by a bevel gear set 404. The guide groove 104 is used to constrain the movement trajectory of the sliding rod 408, ensuring that the sliding rod 408 moves back and forth along a preset path. At the same time, the drive gear 402 drives the driven gear 403 to rotate through meshing. The driven gear 403 drives the bevel gear set 404 to rotate. The power is then transmitted to the turntable 406 through the connecting shaft 405. Finally, the centrifugal protrusion 407 of the turntable 406 cooperates with the limiting groove 409 of the sliding rod 408 to realize the periodic striking of the outer wall of the slag pot body 2 by the striking block 410.

[0027] Furthermore, two sets of tilting mechanism 3 and striking mechanism 4 are provided, and are symmetrically arranged with the vertical reference plane of slag pot body 2 as the symmetrical plane. The vertical reference plane is parallel to the vertical outer wall of the support 1. The synchronous driving on both sides can evenly distribute the force on slag pot body 2 during tilting and striking, avoiding uneven loading or twisting caused by unilateral force application, and significantly improving stability. The symmetrical tilting mechanism can ensure that the center of gravity of slag pot is always controlled, preventing the risk of overturning. The two sets of driven racks 306 mesh with the driving rack 105 through the transmission gear 305, and clamp the slag pot trunnion from both sides simultaneously to form a two-way lock, preventing the trunnion from loosening or misaligning due to insufficient fixation on one side when rotating. The reciprocating motion of the two sets of side striking blocks 410 can cover a larger area of ​​the outer wall of slag pot body 2. The symmetrical vibration promotes the uniform peeling of molten slag on the inner wall and reduces residue. At the same time, the striking blocks 410 made of elastic material reduce the impact damage to the pot body.

[0028] Working principle: The slag pot body 2 is moved into the mounting slot 302 in the moving seat 301 by a bridge crane or mobile crane with special lifting equipment. This initially secures the trunnion of the slag pot body 2. Then, the moving seat 301 is pushed forward along the extension direction of the lead-out slot 101 by the cylinder 5. When the transmission gear 305 inside the moving seat 301 meshes with the driving rack 105, the transmission gear 305 rotates through meshing with the driving rack 105 as the moving seat 301 moves forward. It also rotates through meshing with the driven rack 306, causing 306 to move along the extension direction of the clamping groove 303. The extension direction of the clamping groove 303 is consistent with the forward direction of the moving seat 301, thus providing secondary securing of the trunnion of the slag pot body 2. At this point, the final fixing of the trunnion of the slag pot body 2 is completed, preventing misalignment due to instability during subsequent rotation of the slag pot body 2. When the limiting shaft 307 on the moving seat 301 moves to the end of the lead-out groove 101, the second support foot moves precisely to the inflection point between the horizontal section and the arc end of the flipping groove 102. Simultaneously, the snap-fit ​​block at the bottom of the limiting shaft 307 smoothly inserts into the snap-fit ​​groove on the surface of the rotating shaft 308, making the limiting shaft 307 and the rotating shaft 308 form a whole, preventing the limiting shaft 307 from slipping during rotation of the slag pot body 2, thereby improving the stability of the slag pot body 2 during rotation. With the continuous output of the cylinder 5, the slag pot body 2 moves in an arc with the axis of the rotating shaft 308 as the origin and the first support foot as the radius. The end of the rotating groove 102 represents the maximum rotation arc of the slag pot body 2. At this point, the opening end of the slag pot body 2 forms a negative angle with the horizontal plane, which is greater than -30°. This prevents the slag pot body 2 from rotating too much, causing molten slag to fall onto the support 1. During the rotation of the slag pot body 2, the rotating shaft 308 drives the driving gear 402 to rotate. The driving gear 402 drives the driven gear 403 to rotate through meshing. The transmission ratio between the driving gear 402 and the driven gear 403 is reasonably set to ensure that the driven gear 403 rotates for a long time, providing power for the striking mechanism 4. Specifically, the driven gear 403 drives the bevel gear set 404 to rotate. The bevel gear set 404 drives the turntable 406 to rotate through the connecting shaft 405. The turntable 406 rotates through the protrusion 407 and the limit. The interaction of the slots 409 causes the sliding rod 408 to reciprocate linearly along the striking block 104, thereby causing the striking block 410 at the end of the sliding rod 408 to reciprocately strike the outer wall of the slag pot body 2. The striking block 410 is made of elastic material, ensuring the continuous and smooth operation of the striking mechanism. This removes the molten slag and cooling material from the inner wall of the slag pot body 2, increasing the effective volume of the slag pot body 2 for the next use. After the slag pot body 2 stops rotating and the molten slag inside is completely discharged, the cylinder 5 pulls the moving seat 301 in the reverse direction. When the transmission gear 305 meshes with the driving rack 105 again, the transmission gear 305 rotates in the reverse direction, and through meshing, the driven rack 306 resets, releasing the fixation on the slag pot body 2.The slag pot body 2 is then removed again using a bridge crane or mobile crane for future use.
