Description

Technical Field

[0001] This utility model relates to the field of refractory materials technology, and in particular to a rapid construction device for refractory materials used in steel ladles. Background Technology

[0002] A ladle is used in steel mills and foundries to receive molten steel and perform pouring operations before open-hearth furnaces, electric furnaces, or converters. Ladle metallurgy involves pouring molten steel from the steelmaking furnace into the ladle for further refining. This process removes impurities such as hydrogen, nitrogen, carbon, and sulfur from the molten steel, adjusts the temperature and composition of the steel, and reduces non-metallic inclusions. During the manufacturing of the ladle, a refractory coating is usually applied to the inner surface to further enhance its refractory properties.

[0003] A construction device for environmentally friendly refractory materials in refining steel ladles, with announcement number CN217594986U, has achieved a certain degree of automated spraying of refractory materials. However, in practical applications, its fixed movement of the spraying pipe makes it difficult to adapt to complex inner wall surfaces such as the cylindrical sidewalls and curved bottoms of the steel ladle. This results in spraying blind spots at high points on the sidewalls and at bottom corners, leading to uneven refractory material spraying with localized areas that are too thick or too thin. This not only wastes materials and increases costs but also requires manual secondary repairs, reducing construction efficiency and making it difficult to ensure the stable quality of the ladle lining. Therefore, there is an urgent need to improve the structure of the spraying pipe to make its movement more flexible, adapt to the complex structure of the steel ladle, and achieve efficient and high-quality construction. Utility Model Content

[0004] In view of the problems of fixed movement of the spray pipe in the existing refractory material construction device for steel ladles, which makes it difficult to conform to the complex inner curved surface of the steel ladle, resulting in blind spots, uneven material distribution, and low construction efficiency, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid construction device for refractory materials for steel ladles, comprising symmetrically arranged telescopic rods, with a mounting frame connected to the upper ends of the two telescopic rods. The top of the mounting frame is equipped with a dual-shaft motor, a material box, and a hydraulic pump. The material box contains a mixing assembly.

An adjustment plate is sleeved on the outer side of one end of the hollow shaft, and the adjustment plate is located on the inner side of the two support plates. A fixing component for limiting and supporting the spray pipe is provided between the two adjustment plates. A fixing cylinder is provided on the outer side of the support plate, and a push rod is provided inside the fixing cylinder. A baffle and a spring are sleeved on the outer side of the push rod inside the fixing cylinder, and the spring is located on the side closer to the support plate. One end of the push rod passes through the hollow shaft and is connected to a locking rod. A limiting groove adapted to the locking rod is opened at one end of the hollow shaft and the adjustment plate. Several locking slots are distributed in a semi-circular array on the inner sidewall of the support plate, and the locking slots are adapted to the locking rod. The end of the push rod away from the locking rod passes through the end of the fixing cylinder away from the support plate.

[0008] As a preferred embodiment, the angle adjustment mechanism further includes a reset cylinder, which is disposed above the turntable and is fixedly connected to the connecting plate. The reset cylinder is provided with a rod, and springs and stops are distributed and sleeved on the outside of the rod inside the reset cylinder. The turntable sidewall is symmetrically provided with several insertion holes that are adapted to the rod, and the upper end of the rod is connected to a handle outside the reset cylinder.

[0009] As a preferred embodiment, the fixing component includes a limiting frame symmetrically arranged on both sides of the spray pipe. Two limiting rings are sleeved on the outer side of one end of the spray pipe, and the limiting rings are located on both sides of the limiting frame. Sliding grooves are opened at corresponding positions on the side wall of the adjusting plate away from the turntable. A bidirectional screw is rotatably installed in the sliding groove, and a handle is connected to the upper end of the bidirectional screw above the adjusting plate.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. This utility model allows the pull handle to move the insertion rod out of the insertion hole, thereby rotating the turntable and adjusting the position of the adjustment plate. Then, by pressing and pushing the push rod, the locking rod is moved out of the corresponding limiting groove, which can drag the adjustment plate to rotate around the hollow shaft. This causes the adjustment plate to move the limiting frame, thereby moving the spraying pipe synchronously and changing its angle. This allows the angle of the spraying pipe to be adjusted as needed, thus solving the problems of difficulty in adapting to the complex inner wall curved surface of the steel ladle, resulting in blind spots in spraying, uneven material distribution, and low construction efficiency.

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1-4 As shown, a rapid construction device for refractory materials for steel ladles is provided, including symmetrically arranged telescopic rods 1. The upper ends of the two telescopic rods 1 are connected to a mounting frame 2. The top of the mounting frame 2 is equipped with a dual-shaft motor 3, a material box 4, and a hydraulic pump 5. The material box 4 contains a mixing assembly. The output end of the dual-shaft motor 3 is connected to a rotating pipe 7 below the mounting frame 2. A fixed box 6 is rotatably fitted onto the outside of the rotating pipe 7, and the fixed box 6 is fixedly connected to the mounting frame 2. The lower end of the rotating pipe 7 is connected to a connecting plate 8. Several spray pipes 9 are respectively provided on both sides of the connecting plate 8. The angle adjustment mechanism is connected to the connecting plate 8, thus constructing an overall structural framework that provides basic support for subsequent functions such as angle adjustment and material conveying. The angle adjustment mechanism includes a connector 10, and there are several connectors 10. Several connectors 10 are connected to the connecting plate 8, and one end of the connector 10 is threadedly connected to the spray pipe 9. A turntable 12 is rotatably sleeved on the outer wall of the connector 10. This provides a basic connecting component for the angle adjustment of the spray pipe 9. The threaded connection facilitates subsequent maintenance and replacement, and the rotatably sleeved turntable 12 creates conditions for angle adjustment.

[0027] In this example, the angle adjustment mechanism also includes a support plate 13, which is symmetrically arranged on one side of the turntable 12. A hollow shaft 15 is rotatably embedded in one side of the support plate 13, and an adjusting plate 14 is sleeved on the outer side of one end of the hollow shaft 15. The adjusting plate 14 is located on the inner side of the two support plates 13. A fixing assembly for limiting and supporting the spray pipe 9 is provided between the two adjusting plates 14. A fixing cylinder 16 is provided on the outer side of the support plate 13. A push rod 17 is provided inside the fixing cylinder 16. A baffle 18 and a spring 19 are sleeved on the outer side of the push rod 17 inside the fixing cylinder 16. The spring 19 is located near the support plate 13. One end of the push rod 17 passes through the hollow shaft 15 and is connected to the locking rod 20. The hollow shaft 15 and the adjusting plate 14 have a limiting groove 31 that matches the locking rod 20. The support plate 13 has several locking grooves arranged in a semi-circular array relative to the inner side wall, and the locking grooves match the locking rod 20. The end of the push rod 17 away from the locking rod 20 passes through the fixed cylinder 16 away from the support plate 13. Through the cooperation of the various components of the adjusting mechanism, the spray pipe 9 can be precisely adjusted at multiple angles, solving the problem of difficulty in adapting to the complex inner wall surface of the steel ladle.

[0028] In this example, the angle adjustment mechanism also includes a reset cylinder 21, which is located above the turntable 12 and is fixedly connected to the connecting plate 8. The reset cylinder 21 is provided with a rod 22, and springs 24 and stops 23 are distributed and sleeved on the outside of the rod 22 inside the reset cylinder 21. Several insertion holes adapted to the rod 22 are symmetrically opened on the side wall of the turntable 12. A handle is connected to the upper end of the rod 22 outside the reset cylinder 21. The angle adjustment mechanism is further improved so that the turntable 12 can be stably positioned after the angle is adjusted by rotation, ensuring the reliability of the angle adjustment of the spray pipe 9 and improving the spraying accuracy.

[0029] In this example, the fixing component includes a limiting frame 25, which is symmetrically arranged on both sides of the spray tube 9. Two limiting rings 27 are sleeved on the outer side of one end of the spray tube 9, and the limiting rings 27 are located on both sides of the limiting frame 25. The side wall of the adjusting plate 14 away from the turntable 12 is provided with corresponding grooves. A bidirectional screw 26 is rotatably installed in the groove, and a handle is connected to the upper end of the bidirectional screw 26 above the adjusting plate 14. The two ends of the limiting frame 25 are respectively sleeved on the outer side of the bidirectional screw 26 on both sides, and the limiting frame 25 is threadedly connected to the bidirectional screw 26. This achieves stable clamping and fixing of the spray tube 9, and at the same time, the spacing of the limiting frame 25 can be easily adjusted through the bidirectional screw 26, which facilitates the support, limiting and disassembly of the spray tube 9.

[0030] In this example, the turntable 12 is rotatably connected to the connector 10 via a bearing. The part of the spray tube 9 on one side of the connector 10 is a flexible hose, and the clamp 20 has an L-shaped structure. The bearing connection reduces rotational friction, the flexible hose design makes the angle adjustment of the spray tube 9 more flexible, and the L-shaped clamp 20 is easy to cooperate with the limiting groove 31 and the clamping groove to achieve angle locking.

[0031] Reference Figure 1 and Figure 5 As shown, in this example, the stirring assembly includes a rotating shaft 28, which is rotatably installed inside the material box 4. Several blades 30 are symmetrically arranged on the outer wall of the rotating shaft 28. The upper end of the rotating shaft 28 extends outside the material box 4. The upper end of the rotating shaft 28 is connected to the output end above the dual-shaft motor 3 through a sprocket transmission assembly 29. The stirring assembly is operated by using the power of the dual-shaft motor 3, which reduces the need for additional power devices, improves the overall structural compactness, and can prevent the material in the material box 4 from settling or clumping.

[0032] In this example, the blades 30 on both sides of the rotating shaft 28 are arranged in a circumferentially equidistant array, and the angle between the blades 30 and the rotating shaft 28 is an acute angle; optimizing the distribution and angle of the blades 30 enhances the mixing effect, avoids material sedimentation or agglomeration, and ensures the conveying and spraying effect.

[0033] In this example, drying components 11 are symmetrically arranged on the outer side of the connecting plate 8. The specific structure and working principle of the drying components 11 in this example can be referred to the corresponding part of the above-mentioned reference patent. The input end of the hydraulic pump 5 is connected to the material box 4 through the first conduit, and the output end of the hydraulic pump 5 is connected to the fixed box 6 through the second conduit. The drying components 11 accelerate the drying of the refractory material after spraying. The cooperation between the hydraulic pump 5 and the first and second conduits realizes the stable delivery of materials and improves the construction process.

[0034] During use, the angle of the spray tube 9 is adjusted as follows: Pull the handle outside the reset cylinder 21 to move the insertion rod 22 out of the insertion hole on the side wall of the turntable 12, overcoming the elastic force of the second spring 24. At this time, the turntable 12 can rotate freely. Adjust the adjustment plate 14 to the appropriate position. Then press the push rod 17 to move the locking rod 20 out of the limiting groove 31 on the hollow shaft 15 and the adjustment plate 14, overcoming the elastic force of the first spring 19. This causes the locking rod 20 to move out of the slot. Then drag the adjustment plate 14 to rotate around the hollow shaft 15. The adjustment plate 14 moves the limiting frame 25, which in turn moves the spray tube 9 synchronously, changing the angle of the spray tube 9. After the adjustment is completed, release the push rod 17. The locking rod 20 is locked into the corresponding slot under the action of the first spring 19. Release the handle, and the insertion rod 22 is inserted into the insertion hole of the turntable 12 under the action of the second spring 24, thus locking the angle.

[0035] Refractory material conveying and mixing: When the dual-shaft motor 3 starts, the upper output end drives the rotating shaft 28 to rotate through the sprocket transmission assembly 29. The blades 30 on the rotating shaft 28 rotate accordingly to stir the refractory material in the material box 4 to prevent the material from settling or clumping. At the same time, the lower output end of the dual-shaft motor 3 drives the rotating pipe 7 to rotate. The hydraulic pump 5 draws the uniformly stirred refractory material in the material box 4 into the first conduit, then pumps it into the fixed box 6 through the second conduit. The material enters the rotating pipe 7 through the feed port on the rotating pipe 7, and finally is distributed to each spraying pipe 9 by the connecting plate 8.

[0036] Spraying operation: The spray pipe 9, with its angle adjusted, sprays the refractory material onto the inner wall of the ladle. Since the spray pipe 9 is threadedly connected to the connector 10 and is clamped by the limit bracket 25, it can be easily disassembled and reassembled if the spray pipe 9 needs to be replaced or maintained.

[0037] Drying operation: The drying component 11 on the outside of the connecting plate 8 is activated to dry the sprayed refractory material, accelerate the drying process, improve construction efficiency, and ensure the construction quality of the steel ladle lining.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
