Technical Field
[0001] This utility model relates to the field of bottom-blown furnace technology, and in particular to the connection component between the steel wire rope for furnace body hoisting and the furnace body. Background Technology
[0002] A bottom-blown furnace is a furnace that uses gas injected into the bottom of the furnace to contact the material inside, thus achieving the purpose of smelting and melting. Depending on the type and purpose of the injected gas, bottom-blown furnaces can be divided into several types, such as oxygen bottom-blown furnaces and gas-fired bottom-blown furnaces. Among them, oxygen bottom-blown furnaces are particularly widely used in steelmaking.
[0003] For example, publication number CN209957873U discloses a novel oxygen-enriched bottom-blown furnace, belonging to the field of non-ferrous metal smelting. Its purpose is to address the problem in existing oxygen-enriched bottom-blown furnaces where the oxygen lance arrangement causes molten metal to accumulate and churn within the molten pool, eroding the furnace walls and reducing the furnace's lifespan. The furnace body includes several oxygen lances arranged at a zero-degree angle at its bottom. This invention can extend the service life of the oxygen-enriched bottom-blown furnace.
[0004] This patent can extend the service life of bottom-blown furnaces. However, existing bottom-blown furnaces are directly tied to wire ropes when hoisted, which can cause the furnace to fall off during hoisting, posing a significant safety hazard.
[0005] Therefore, we propose a new type of connection assembly between the steel wire rope used for furnace body hoisting and the furnace body. Utility Model Content

[0008] Preferably, the limiting frame is L-shaped, and the motor is electrically connected to an external power source via a control switch. The L-shape can achieve the effect of preventing the wire rope from slipping off.
[0009] Preferably, the first gear is matched with the second gear in position and size, and the first gear and the second gear are connected in meshing connection, which can drive the bidirectional screw to rotate.
[0010] Preferably, the bidirectional screw is connected with the moving block through the threaded hole, and the bidirectional screw rotates to adjust the position of the two groups of moving blocks through the threaded connection.
[0011] Preferably, the bottom blowing furnace is provided with the protection limiting assembly on both sides, the protection limiting assembly comprises a limiting block, four groups of springs are connected in the limiting block, and the limiting block can limit the moving block.
[0012] Preferably, the front surface of the four groups of springs is connected with a push plate, four guide rods are connected to the four corners of the side close to the limiting block of the push plate, and the impact force between the moving block and the limiting block can be reduced through the springs.
[0013] Preferably, a guide hole is formed in the surface of the limiting block close to the impact block, and the guide hole and the guide rod can guide.
[0014] Compared with the prior art, the utility model has the advantages and positive effects that,
[0015] 1、 in the utility model, when hoisting, the two groups of limiting frames can be moved to both sides at the same time through the motor, then the steel wire rope is passed through the bottom of the limiting frame, and then the limiting frame is moved to the inside through the operation of the motor, so that the limiting of the steel wire rope is realized, the situation that the steel wire rope is easy to fall off during hoisting is prevented, and the safety hazard during hoisting is avoided.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Please see Figures 1-4 This utility model provides a technical solution: a connection assembly between the steel wire rope for hoisting the furnace body and the furnace body, including a bottom-blown furnace 1, an anti-fall-off assembly 2 connected to the top of the bottom-blown furnace 1, the anti-fall-off assembly 2 including a fixing box 201, a bidirectional screw 202 inserted into the inside of the fixing box 201, a motor 204 connected to the top of the fixing box 201, a second gear 205 connected to the output end of the motor 204, a first gear 203 connected to the surface of the bidirectional screw 202 near the second gear 205, and moving blocks 206 connected to both sides of the bidirectional screw 202, with threaded holes 207 opened inside the moving blocks 206, and limit frames 208 connected to the surfaces of both sets of moving blocks 206.
[0025] like Figure 2 As shown, the limit frame 208 is L-shaped, and the motor 204 is electrically connected to an external power source through a control switch. The L-shape can achieve the effect of preventing the wire rope from slipping off.
[0026] like Figure 2 As shown, the position and size of the first gear 203 match the position and size of the second gear 205. The first gear 203 and the second gear 205 form a meshing connection, which can drive the bidirectional screw 202 to rotate.
[0027] like Figure 1 and Figure 2As shown, the bidirectional screw 202 is connected to the moving block 206 through the threaded hole 207. When the bidirectional screw 202 rotates, it will adjust the position of the two sets of moving blocks 206 through the threaded connection.
[0028] like Figure 4 As shown, protective limiting components 3 are connected to both sides of the bottom blowing furnace 1. The protective limiting components 3 include limiting blocks 301. Four sets of springs 302 are connected inside the limiting blocks 301. The limiting blocks 301 can limit the movement of the moving block 206.
[0029] like Figure 1 and Figure 4 As shown, the front surfaces of the four sets of springs 302 are connected to push plates 303. Guide rods 305 are connected to the four corners of the push plate 303 near the limit block 301. The impact force between the moving block 206 and the limit block 301 can be reduced by the springs 302.
[0030] like Figure 1 and Figure 4 As shown, the limiting block 301 has a guide hole 306 on its surface near the collision block 304. The guide hole 306 and the guide rod 305 can play a guiding role.
[0031] The usage and working principle of this device are as follows: When hoisting the bottom-blown furnace 1, two sets of wire ropes can be passed through the bottom of the two sets of limit frames 208 respectively. Then, the forward rotation function of the motor 204 can be started, so that the motor 204 can drive the first gear 203 to rotate forward through the output end, and mesh with the second gear 205 in the forward direction. In this way, the second gear 205 drives the bidirectional screw 202 to rotate forward. At the same time, the bidirectional screw 202 will also rotate forward through the threaded hole 207 and the moving block 206, thereby causing the two sets of moving blocks 206 to move inward at the same time, realizing the limitation of the wire ropes. Then, the bottom-blown furnace 1 can be hoisted by the wire ropes and the hoisting equipment. After being installed at the designated location, the reverse rotation function of the motor 204 can be activated to drive the second gear 205 to reverse, thereby meshing with the first gear 203 in the opposite direction. This causes both sets of moving blocks 206 to move to both sides simultaneously, and drives the limiting frame 208 to move as well, so that the wire rope can be taken out from the bottom of the limiting frame 208. In this way, the wire rope can be limited during hoisting, preventing it from falling off easily and avoiding safety hazards during hoisting. When the moving block 206 moves and collides with the collision block 304, the collision block 304 will push the push plate 303 to squeeze the spring 302, which plays a role in shock absorption, reducing the impact force during collision and improving the service life of the limiting block 301.
[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
