[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] A steelmaking converter furnace body stabilizing buffer device according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0023] Example 1

[0024] See also Figures 1 to 3 The utility model provides an embodiment of a steel-making converter furnace body stabilizing buffer device, comprising a buffer device body 1, a stabilizing device body 2, and a steel-making furnace 3, wherein the stabilizing device body 2 is installed above the buffer device body 1, and the steel-making furnace 3 is installed inside the stabilizing device body 2;

[0025] The buffer device body 1 includes a base 4, a fixed frame 5, a shock absorbing spring 6, two support plates 8, a movable shaft 9, and a fixed block 10. The fixed frame 5 is fixedly connected to both sides of the top of the base 4, one end of the two support plates 8 is rotatably connected to one side of the fixed block 10 and the base 4, and the other ends of the two support plates 8 are rotatably connected to each other, and the two ends of the shock absorbing spring 6 are rotatably connected to one end of the two support plates 8;

[0026] The stabilizing device body 2 includes two limit rings 11 and a snap-fit ​​positioning assembly. The two limit rings 11 are fixedly connected to the two end surfaces of the fixed block 10 . The inner sides of the two limit rings 11 are provided with a snap-fit ​​positioning assembly, and the snap-fit ​​positioning assembly is arranged on the outer wall of the steelmaking furnace 3 .

[0027] like Figure 1 , Figure 2 As shown, the two guide bars 7 are fixedly connected to the fixed frames 5 on both sides respectively, and the fixed block 10 is slidably connected to the side wall of the fixed frame 5 through the guide bars 7 .

[0028] It should be noted that, by applying force to the fixed block 10 through the steelmaking furnace 3, the fixed block 10 rises and falls in the vertical direction under the limiting action of the two guide bars 7 and the fixed frames 5 on both sides, thereby avoiding the steelmaking furnace 3 from being offset when moving. The setting of the base 4 and the top fixed frame 5 can increase the stability of the overall structure.

[0029] like Figure 1 , Figure 2 As shown, the movable shaft 9 is fixedly installed on the side of the fixed block 10 , and the movable shaft 9 is installed at the overlap of the two support plates 8 , and the overlap of the two support plates 8 is rotatably connected through the movable shaft 9 .

[0030] It should be noted that, by applying force to the fixed block 10, the movable shaft 9 applies force to the upper support plate 8, thereby causing the overlapping part of the two support plates 8 to rotate around the movable shaft 9, thereby changing the angle of the two support plates 8, thereby achieving the purpose of reducing the shaking of the steelmaking furnace 3 when it descends.

[0031] like Figure 1 As shown, the shock absorbing spring 6 is fixedly mounted on one end of the two connecting blocks 17 , and the other ends of the two connecting blocks 17 are mounted on the end surfaces of the two supporting plates 8 through fixed shafts.

[0032] It should be noted that the two connecting blocks 17 are squeezed by the two supporting plates 8 to move the two connecting blocks 17 inward, thereby causing the two connecting blocks 17 to compress the compression damping spring 6, thereby achieving the purpose of providing a buffer for the steelmaking furnace 3.

[0033] like Figure 1 , Figure 3 As shown, the clamping positioning assembly includes two fixing rings 12, a threaded screw 13, a fixing pin 15, and a supporting spring 16. The two fixing rings 12 surround the outer wall of the steelmaking furnace 3, and the fixing pin 15 is fixedly installed on the two end surfaces of the two fixing rings 12.

[0034] Two fixing rings 12 surround the outer wall of the steelmaking furnace 3, and the fixing pin 15 is fixedly installed on the two end surfaces of the two fixing rings 12. Rotating the fixing pin 15 can make the inner walls of the two sections of the fixing rings 12 fit more closely with the outer wall of the steelmaking furnace 3, preventing the steelmaking furnace 3 from falling off during injection.

[0035] like Figure 3 As shown, the support spring 16 is supported on the butt-jointed end surfaces of the two fixing rings 12 , and the support spring 16 is sleeved on the outer wall of the fixing pin 15 .

[0036] It should be noted that, through the setting of the fixed pin 15 and the fixed ring 12, when in use, under the action of the limiting function of the fixed pin 15, the two fixed rings 12 can be brought close to each other, so that the fixed ring 12 squeezes the support spring 16. At this time, the support spring 16 produces a certain elasticity, so that the fixed ring 12 is in close contact with the fixed pin 15, thereby preventing the hidden danger of the fixed pin 15 falling off due to long-term use.

[0037] like Figure 3 As shown, the threaded hole on the side wall of the limiting ring 11 is matched with the threaded screw 13 and installed, and the other end of the threaded screw 13 is rotatably connected to the side wall of the fixing ring 12 .

[0038] It should be noted that, by the threaded screw 13 cooperating with the thread of the limiting ring 11 , the fixing ring 12 is caused to shrink inwards or expand outwards, thereby preventing the steelmaking furnace 3 from being unusable due to different specifications.

[0039] like Figure 3 As shown, one end of the threaded screw 13 is fixedly connected to a handle 14. By rotating the handle 14, the threaded screw 13 and the limiting ring 11 are threadedly matched. The fixing ring 12 can be pushed by the threaded screw 13, thereby facilitating the adjustment of the distance between the two fixing rings 12.

[0040] Working principle: First, connect the base 4 with the fixed frame 5. The impact force generated by the injection of the steelmaking furnace 3 will cause the steelmaking furnace 3 to descend. At this time, the fixed block 10 slides along the inner wall of the guide strip 7 to prevent the steelmaking furnace 3 from deflecting when it descends. The steelmaking furnace 3 is installed in the middle of the two-section fixed ring 12. Rotating the fixed pin 15 can make the inner wall of the two-section fixed ring 12 fit more closely with the outer wall of the steelmaking furnace 3. The fixed pin 15 rotates to push the fixed ring 12 to move inward. The fixed ring 12 squeezes the support spring 16. The support spring 16 has a certain elasticity, which can make the fixed ring 12 fit more closely with the steelmaking furnace 3. The handle 14 rotates to drive the threaded screw 13 The threaded screw 13 rotates and cooperates with the thread of the limit ring 11 to push the fixed ring 12, so that the fixed ring 12 moves inward or outward to prevent the steel-making furnace 3 from being unusable due to different specifications. The fixed block 10 moves downward synchronously under the force of the steel-making furnace 3, and the fixed block 10 squeezes the upper support plate 8 downward. At this time, the two support plates 8 rotate along the movable axis 9 to produce deformation, which can provide a certain buffer for the steel-making furnace 3. When the two support plates 8 are deformed under force, the shock-absorbing spring 6 will be squeezed through the connecting block 17. The shock-absorbing spring 6 will be squeezed. When the shock-absorbing spring 6 is squeezed, it will be compressed and provide a certain elastic force, so that the steel-making furnace 3 is more stable when it descends.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
