Technical Field

[0001] The invention relates to the technical field of ladle turrets, in particular to a ladle turret with adjustable lifting positions. Background Art

[0002] The ladle turret is a device for carrying and supporting the ladles for pouring in the continuous casting process of the steel plant. It is set between the molten steel receiving span and the pouring span. The two ends of the slewing arm carry the ladles. The slewing arm on one side of the molten steel receiving span receives the ladles, rotates half a circle, stops above the tundish, and releases the molten steel for continuous casting. The empty ladles after pouring are rotated half a circle by the turret and then transported back to the molten steel receiving span. The ladle turret generally has complex structure, high working environment temperature of the main hydraulic cylinder, serious oil leakage, poor braking effect, reverse motion impact easily damages the transmission chain, equipment installation is difficult, and equipment investment cost is high. At present, the ladle The turret adopts a four-link lifting mechanism with many large structural parts. The structural parts are connected by pins, and the rotating pairs use a large number of spherical bearings, which increases the cost of the equipment. In addition, since the ladle turret is a molten steel transfer equipment between steelmaking and continuous casting, it is often arranged on the common axis of the steelmaking span and the casting span of the factory building. The equipment is in the blind spot of the overhead crane lifting and is not easy to install and maintain. The force on the ladle turret varies greatly. However, no matter what the circumstances, it is necessary to ensure that the ladle turret rotates smoothly and the positioning is accurate. The impact on the mechanical parts should be minimized as much as possible during starting and stopping. In order to reduce the fluctuation of the liquid level and the temperature drop in the tundish, the rotation time should be shortened.

[0019] The present invention provides a ladle turret with adjustable lifting position. It has the following beneficial effects:

[0020] 1. The ladle turret with adjustable lifting position has a sliding assembly that slides on the surface of the slide rail. The slide rail makes the sliding assembly move up and down more smoothly, driving the equipment to rotate the turntable through the engagement of the tooth surface. The height position of the molten steel tank is adjustable, and the rotation of the molten steel tank makes the continuous die-casting effect better.

[0021] 2. The ladle turret with adjustable lifting position has two external gears, which makes the thrust more reliable when the internal gear rotates and the internal gear is not easy to deflect. The rotation of the screw causes the lifting body to be driven to rotate near the internal thread groove.

[0023] 4. The ladle turret with adjustable lifting position has one end of a fixed rod fixedly connected to the driving wall, and the other end of the fixed rod limits the internal threaded barrel to prevent unstable rotation when the threaded rod drives the internal threaded barrel to rotate. The internal threaded barrel pushes the driving walls closer to each other, one end of the threaded rod extends through the opening of the disc body, the swinging wall is pushed by the driving wall, and the slider slides on the inner side of the slot. The pressure of the fixed rod makes the push of the internal threaded barrel more stable and reliable.

[0024] 5. The ladle turret with adjustable lifting position drives the walls to be moved closer to each other to lift and clamp the molten steel tank. The swing walls rotate in opposite directions, and the slider slides on the inner side of the slot. The hydraulic pressure in the hydraulic cylinder applies resistance to the rotation of the swing wall, so that the rotation of the swing wall can be supported. The surface of the rib plate is in direct contact with the surface of the slide rail. When the screw drives the lifting body to slide, the rib plate makes the hydraulic cylinder more stable when lifting, thereby reducing the impact on the molten steel inside the molten steel tank and avoiding the instability and shaking of the molten steel tank.

[0035] like Figure 1-Figure 3 As shown, the present invention provides a technical solution: a ladle turret with adjustable lifting position, comprising

[0036] A fixed platform 1, the surface of which is fixedly connected to a driving device 2, the top of which is rotatably connected to a rotating platform 3, the lower portion of the surface of the rotating platform 3 being engaged with the output end of the driving device 2;

[0037] The lifting mechanism 4 is fixedly connected to the middle position of the top of the rotating table 3. The rotating table 3 drives the ladle to rotate. The lifting mechanism 4 adjusts the lifting height of the ladle through the lifting characteristics of the thread. It includes a slide rail 41. The top of the slide rail 41 is fixedly connected to a rotating component 43. The output end of the rotating component 43 is fixedly connected to a screw rod 42. The surface of the screw rod 42 is connected to a sliding component 44 via a thread. The rotating component 43 drives the screw rod 42 to rotate, so that the sliding component 44 slides on the inner side of the slide rail 41 to adjust the lifting height of the ladle.

[0038] The bottom of the sliding assembly 44 is fixedly connected to the support platform 45, the bottom end of the screw rod 42 is rotatably connected to the top of the rotating platform 3, and the surface of the sliding assembly 44 is fixedly connected to the hydraulic cylinder 46;

[0039] The clamping mechanism 5 is used to clamp the ladle and is arranged on the surface of the slide rail 41 near the sliding assembly 44. Before the ladle is lifted, the clamping mechanism 5 is located below the ladle. The clamping mechanism 5 buffers the clamping force of the ladle through the scissors fork mechanism.

[0040] When in use, there are two molten steel tanks 6, and the clamping mechanism 5 clamps the surface of the molten steel tank 6. The rotating component 43 drives the screw rod 42 to rotate.

[0042] When in use, the connecting plate 431 supports the output device 432, and the output end of the output device 432 drives the external gear 433 to rotate. The surface of the external gear 433 rotates the internal gear 434 through tooth surface meshing, and the rotation of the internal gear 434 causes the screw rod 42 to rotate. There are two external gears 433, which makes the thrust more reliable when the internal gear 434 rotates, and the internal gear 434 is not easy to deflect. The rotation of the screw rod 42 causes the lifting body 441 to be driven to rotate and move near the internal thread groove 442. By controlling the rotation direction of the internal gear 434, the lifting body 441 can be controlled to move up or down. By using mechanical thread transmission, the device is more stable during operation, and the deceleration is fast and the load-bearing capacity is effectively improved.

[0043] like Figure 3 、 Figure 6As shown, the output end of the rotating assembly 43 is fixedly connected to a screw rod 42, and the surface of the screw rod 42 is connected to a sliding assembly 44 through a thread. The rotating assembly 43 drives the screw rod 42 to rotate, so that the sliding assembly 44 slides on the inner side of the slide rail 41 to adjust the lifting height of the ladle. The bottom of the sliding assembly 44 is fixedly connected to a support platform 45, and the bottom end of the screw rod 42 is rotatably connected to the top of the rotating table 3. The surface of the sliding assembly 44 is fixedly connected to a hydraulic cylinder 46. The clamping mechanism 5 includes a threaded rod 51, one end of the threaded rod 51 is fixedly connected to the output end of the sliding assembly 44, and the end of the threaded rod 51 away from the sliding assembly 44 is threadedly connected to a limiting assembly 52, the surface of the limiting assembly 52 is fixedly connected to a support rod 53, and the end of the support rod 53 away from the limiting assembly 52 is fixedly connected to a driving wall 54, and the inner side of the driving wall 54 is rotatably connected to a stabilizing assembly 56, and the surface of the driving wall 54 is fixedly connected to a clamping block 55, and the surface of the clamping block 55 is fixedly connected to the molten steel tank 6.

[0044] When in use, the surface of the molten steel tank 6 is fixedly connected to the lifting block. Before lifting the molten steel tank 6, the driving wall 54 is in the lower position of the device and close to the lifting block of the molten steel tank 6. The sliding component 44 drives the threaded rod 51 to rotate, and the limiting component 52 pushes the driving wall 54 to move close to the sliding component 44. The interior of the hydraulic cylinder 46 is hydraulically connected. When the driving walls 54 approach each other, the stabilizing component 56 is combined. The hydraulic pressure of the hydraulic cylinder 46 makes the stabilizing component 56 resisted and buffered when it is combined. The driving wall 54 smoothly drives the clamping block 55 to clamp the lifting block of the molten steel tank 6. Subsequently, the rotating component 43 drives the screw rod 42 to rotate, which solves the problem of how to stably clamp and position the molten steel tank 6.

[0045] like Figure 6 、 Figure 7 、 Figure 8 As shown, the limiting assembly 52 includes an internal threaded cylinder 521, the inner side surface of the internal threaded cylinder 521 is connected to the surface of the threaded rod 51 through a thread, the surface of the internal threaded cylinder 521 is fixedly connected to the fixing rod 522, the end of the fixing rod 522 away from the internal threaded cylinder 521 is fixedly connected to the disk body 523, an opening 524 is provided in the middle position of the surface of the disk body 523, the surface of the disk body 523 is fixedly connected to the surface of the support rod 53, the stabilizing assembly 56 includes a slot 561, the slot 561 is provided on the surface of the driving wall 54, the inner side surface of the driving wall 54 is rotatably connected to the swinging wall 562, the surface of the swinging wall 562 is fixedly connected to the slider 563, and the surface of the swinging wall 562 is rotatably connected to the rotating shaft 564.

[0046] When in use, there are two internal threaded barrels 521 and threaded rods 51, and the rotation directions of the threaded rods 51 are opposite, so that the two internal threaded barrels 521 move toward each other, one end of the fixed rod 522 is fixedly connected to the driving wall 54, and the other end of the fixed rod 522 limits the internal threaded barrel 521 to prevent the threaded rod 51 from driving the internal threaded barrel 521 to rotate unstably. The internal threaded barrel 521 pushes the driving walls 54 to approach each other, and one end of the threaded rod 51 extends through the opening 524 of the disc body 523. The swinging wall 562 is pushed by the driving wall 54, and the slider 563 slides on the inner side of the slot 561. The pressure of the fixed rod 522 makes the pushing of the internal threaded barrel 521 more stable and reliable.

[0048] When in use, the output end of the hydraulic cylinder 46 is fixedly connected to the surface of the swing wall 562, and the two swing walls 562 are rotationally connected through the rotating shaft 564. When the driving walls 54 are driven close to each other to lift and clamp the molten steel tank 6, the swing walls 562 rotate in opposite directions, and the slider 563 slides on the inner side of the slot 561. The hydraulic pressure in the hydraulic cylinder 46 applies resistance to the rotation of the swing wall 562, so that the rotation of the swing wall 562 can be supported. The surface of the rib 444 is in direct contact with the surface of the slide rail 41. When the screw rod 42 drives the lifting body 441 to slide, the rib 444 makes the hydraulic cylinder 46 more stable when lifting, thereby reducing the impact on the molten steel inside the molten steel tank 6 and avoiding instability and shaking of the molten steel tank 6.
