Description

Technical Field

[0001] The utility model relates to the technical field of converter ball joint maintenance, in particular to a furnace body ball joint maintenance mechanism for a wide plate converter. Background Art

[0002] In the metallurgical industry, wide-plate converters are crucial equipment, primarily used for producing molten steel and casting large castings. Spherical joint supports support the furnace body, tightly connecting the furnace shell to the support ring, enabling the support ring to drive the furnace shell's rotation. Each converter is equipped with three spherical joint supports: two on the tapping side at a 30° angle to the trunnion centerline, and one on the charging side at a 90° angle to the trunnion centerline.

[0003] The traditional method for replacing spherical joint supports is to first remove the furnace body's refractory materials, then lift the entire furnace body before replacing the spherical joint supports. During actual spherical joint maintenance, removing the upper spherical joint degrades the support performance of the support ring on the outer wall of the furnace body. Furthermore, because the three spherical joints are not removed simultaneously, the center of gravity of the furnace body shifts relative to the support ring during this process, making subsequent adjustments very difficult and delaying the maintenance quality and duration.

[0004] To this end, the utility model proposes a furnace body ball joint maintenance mechanism for a wide plate converter. Utility Model Content

[0011] The utility model has at least the following beneficial effects:

[0012] 1. In the present invention, when disassembling a single ball joint, the slider corresponding to the ball joint is pulled out from the outside of the connecting block. During this process, both sides of the center of the furnace body lose equal weight, so that the two sets of sliders and ball joint components remaining above the furnace wall support ring are still in a state of center of gravity balance. By continuing to replace the ball joint in this way, the center of gravity can always be kept in a relatively balanced state during the maintenance of the ball joint, reducing the offset of the furnace body and making the maintenance work smoother and more efficient.

[0013] 2. In the present invention, when a single ball joint is disassembled, the center of gravity of the ball joint component relative to the corresponding position of the furnace body will be offset. At this time, the slider will be squeezed by the furnace body, which will increase, thereby squeezing multiple inclined plates at the bottom of the slider. The elastic force of spring 1 will disperse the pressure in this process to prevent the gravity offset generated at the moment the weight of the ball joint disappears from causing excessive squeezing of the support ring surface, while also reducing the center offset of the furnace wall.

[0022] See also Figure 1-6 The utility model provides a technical solution: a furnace body ball joint maintenance mechanism for a wide plate converter, comprising:

[0023] Example 1:

[0024] The furnace wall 1, the outer wall of the furnace wall 1 is provided with an eaves 2 and is fixedly connected to the eaves 2, the outer wall of the furnace wall 1 is also provided with a support ring 3, the furnace wall 1 and the inner wall of the support ring 3 are in contact with each other, the bottom of the support ring 3 is provided with a support 4, one side of the support 4 is fixedly connected to the furnace wall 1, the support 4 is used to support the support ring 3, a plurality of ball joint components 5 are provided between the eaves 2 and the support ring 3, the eaves 2 and the support ring 3 are connected to each other through the ball joint components 5, the above is the existing technology, so it will not be repeated.

[0025] In this scheme, multiple cylinders 6 are provided between the eaves 2 and the support ring 3. There are two cylinders 6, which are respectively located on the central axis of the ear shaft of the support ring 3. The bottom of the cylinder 6 is fixedly connected to the support ring 3, and the top is in contact with the eaves 2, which is used to lift or lower the eaves 2 and the furnace wall 1 during maintenance. Multiple connecting blocks 7 are provided under the eaves 2 and are fixedly connected to it by bolts. The outer wall of the connecting block 7 is provided with a slider 8, which is slidably connected to the connecting block 7. The dead weight of the slider 8 is equal to the dead weight of the ball joint component 5. There are three sliders 8 and the ball joint component 5. The line connecting the center points of the slider 8 and the ball joint component 5 is on the same plane as the central vertical plane of the furnace wall 1; the distribution position of the slider 8 on the support ring 3 corresponds one-to-one to the position of the ball joint component 5, so the distribution of gravity in each area of ​​the gravity eaves 2 and the furnace wall 1 is also in a balanced state, providing a favorable environment for subsequent maintenance work.

[0026] The outer wall of the bottom end of the slider 8 is provided with a fixed cylinder 9, and the slider 8 is slidably connected to the fixed cylinder 9. The bottom of the fixed cylinder 9 is in contact with the support ring 3. The distance from the bottom of the fixed cylinder 9 to the upper end of the slider 8 is equal to the distance from the bottom surface of the eaves 2 to the support ring 3, which makes the combined parts of the fixed cylinder 9 and the slider 8 cooperate with the two oil cylinders 6 to provide auxiliary support for the eaves 2 and enhance the stability of the ball joint component 5 during the maintenance process; the end of the connecting block 7 is provided with a fixed plate 12 and fixedly connected thereto, and a limiting column 13 is provided inside the fixing plate 12, and the limiting column 13 slides freely inside the fixing plate 12, and the outer wall of the limiting column 13 is provided with a slide cylinder 14 and is rotatably connected thereto, and the outer wall of the slide cylinder 14 is provided with a fixing plate 2 15 and It is slidably connected to it, one side of the fixed plate 2 15 is fixedly connected to the slider 8, and a spring 2 16 is provided on the outside of the slide 14. The two ends of the spring 2 16 are respectively fixedly connected to the end of the slide 14 and the fixed plate 2 15. The inclined portion 17 of the limiting column 13 is in contact with the edge of the through hole of the fixed plate 12; the limiting column 13 includes an inclined portion 17 and a curved portion 18. The interior of the fixed plate is provided with a magnet 19 and a magnet 2 20. The magnet 19 and the magnet 2 20 are both fixedly connected to the fixed plate 12. The curved portion 18 has a magnetic force that attracts the magnet 19, and the curved portion 18 has a magnetic force that attracts the magnet 2 20. The attractive magnetic force can make the rotation position of the limiting column 13 inside the fixed plate 12 more stable;

[0027] The sliding effect of the slider 8 outside the connecting block 7 can be limited or unlocked by rotating the direction of the inclined portion 17 of the limiting column 13. When the curved portion 18 and the magnet 2 20 are attracted to each other, the slider 8 will not be able to slide to the outside of the connecting block 7. The slider 8 will be in a limited state, so that the slider 8 strengthens the stability of the support of the eaves 2. When the slider 8 needs to be removed, the curved portion 18 can be rotated to the magnet 1 19 for adsorption. At this time, the slider 8 is slid again, and the inclined portion 17 will resist the edge of the through hole of the fixed plate 12. Under the elastic force of the spring 2 16, the limiting column 13 slides downward until the bottom of the fixed plate 12 contacts the end of the limiting column 13, so that the slider 8 can be smoothly pulled out of the connecting block 7.

[0028] A pressure detector 21 is provided on the outer wall of the fixed cylinder 9 and is fixedly connected to the same. The sensing part at the end of the pressure detector 21 is in contact with the furnace wall 1. When the furnace wall 1 shakes slightly due to unstable center of gravity during maintenance, the furnace wall 1 will resist the pressure detector 21, and then the pressure detector 21 will transmit the measured deviation data to the receiving system to monitor the deviation of the furnace wall 1 in real time so as to adjust the deviation in time.

[0029] During the maintenance process, when disassembling a single ball joint, the limit column 13 can be rotated to make the curved surface 18 and the magnet 19 attract each other, and the slider 8 corresponding to the ball joint is pulled out from the outside of the connecting block 7. During this process, both sides of the center of the furnace body lose equal weight, so that the two groups of sliders 8 and the ball joint component 5 remaining above the furnace wall 1 support ring 3 are still in a state of center of gravity balance. By continuing to replace the ball joint in this way, the center of gravity can be kept relatively balanced during the maintenance of the ball joint, reducing the offset of the furnace body and making the maintenance work smoother and more efficient.

[0030] According to the above embodiment, embodiment 2,

[0031] A plurality of inclined plates 10 are provided inside the fixed cylinder 9. The bottom of the inclined plates 10 is fixedly connected to the inner wall of the bottom of the fixed cylinder 9. The plurality of inclined plates 10 are symmetrically distributed around the center. A spring 11 is provided on the inner wall of the inclined plates 10. The two ends of the spring 11 are respectively fixedly connected to the bottom surface of the inclined plates 10 and the inner wall of the fixed cylinder 9. The inclined plates 10 themselves are elastic, and the top surface of the inclined plates 10 contacts the bottom of the slider 8.

[0032] When a single ball joint is disassembled, the center of gravity of the ball joint component 5 relative to the corresponding position of the furnace body will be offset. At this time, the slider 8 will be squeezed by the furnace body, which will increase, and then squeeze the multiple inclined pieces 10 at the bottom of the slider 8. The elastic force of spring 11 will disperse the pressure in this process to prevent the gravity offset caused by the weight of the ball joint from causing excessive squeezing on the surface of the support ring 3 at the moment when the weight of the ball joint disappears, and also reduce the center offset of the furnace wall 1.
