Description

Technical Field

[0001] This utility model relates to the field of steel metallurgical equipment, and in particular to a ladle cover structure that is not easily displaced. Background Technology

[0002] In iron and steel metallurgical production, the ladle is the core equipment for holding and transferring molten steel. The stability of the ladle cover directly affects the temperature control of molten steel, production safety and energy utilization efficiency. Molten steel needs to stay in the ladle for a long time throughout the entire process from converter tapping, refining to continuous casting. If the ladle cover shifts, it will lead to increased heat loss on the surface of the molten steel, which will not only increase the energy consumption of subsequent refining processes, but may also cause quality defects in the continuously cast billets due to fluctuations in the temperature of the molten steel.

[0003] During the ladle cover opening and closing process, when the insert teeth of the ladle cover opening and closing mechanism engage with the forked finger seat of the ladle cover, the lack of a precise and effective positioning mechanism can easily cause the insert teeth to shift when they are inserted into the forked finger seat. This results in the ladle cover not being able to be aligned smoothly and accurately during installation or disassembly, which in turn causes the ladle cover to shift when it is closed. To address this issue, a ladle cover structure that is less prone to shifting is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a steel ladle cover structure that is not easily shifted, aiming to improve the problem in the prior art that "the steel ladle cover is easy to shift due to the lack of a precise positioning mechanism when the insert teeth and the fork finger seat cooperate during the opening and closing operation".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel ladle cover structure that is not easily deviated, comprising a steel ladle cover, a positioning hook fixedly connected to the left side of the steel ladle cover, three sets of triangularly distributed interdigitated seats fixedly connected to the upper part of the steel ladle cover, each set of interdigitated seats having a pin inserted inside, and positioning components provided on the two sets of interdigitated seats on the right side, the positioning components including a guide plate sleeved outside the pin, a positioning block fixedly connected to the left surface of the guide plate, sliding plates fixedly connected to the left and right sides of the front surface of the positioning block, three sets of positioning rods vertically and evenly fixedly connected between the two sets of sliding plates on the front surface of the positioning block, a fixing frame passing through and slidably connected to the outer walls of the three sets of positioning rods, the fixing frame being fixedly connected to the steel ladle cover, and the fixing frame and the positioning block being elastically connected by springs respectively sleeved on the outer walls of the three sets of positioning rods, the outer wall of the steel ladle cover also having an anti-deviation component for limiting deviation.

[0006] As a further description of the above technical solution: The positioning block is designed to be triangular in shape.

[0007] As a further description of the above technical solution: The fixing frame is T-shaped, with its horizontal part fixedly connected to the steel ladle cover, and its vertical part having a guide hole for the positioning rod to pass through.

[0008] As a further description of the above technical solution: The positioning components are configured in two sets, and the two sets of positioning components are symmetrically arranged with the center line of the pin shaft as the axis of symmetry, and the guide plates of the two sets of positioning components are arranged opposite each other.

[0009] As a further description of the above technical solution: The anti-deviation component includes two sets of guide blocks, which are fixedly connected to the front and rear outer walls of the ladle cover and are symmetrically arranged along the center line of the ladle cover.

[0010] As a further description of the above technical solution: The opposing surfaces of the two sets of guide blocks are set as inclined surfaces, which gradually slope downwards and inwards.

[0011] As a further description of the above technical solution: The top of the inclined surface of the guide block is set as an arc-shaped surface between the top of the inclined surface and the bottom of the steel ladle cover.

[0012] As a further description of the above technical solution: The outer wall of the pin is fitted with a buffer sleeve, which is made of high-temperature resistant elastic material.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by means of the inclined contact between the positioning block and the insert tooth, and in conjunction with the elastic force of multiple sets of springs, when the insert tooth of the ladle capping mechanism is inserted, the two sets of guide plates form a clamping structure, which can automatically center the insert tooth and stably position it between the two sets of guide plates. This ensures that the insert tooth always remains in the accurate center position during the insertion process, improves the accuracy and stability of ladle cap closing during the capping operation, and ensures the smooth progress of production.

[0014] 2. In this utility model, two sets of symmetrical guide blocks contact the outer wall of the ladle opening through a downwardly inward inclined surface. The inclined surface positioning principle effectively further restricts the offset of the ladle cover. At the same time, the arc-shaped surface connection between the top of the inclined surface of the guide block and the bottom of the ladle cover can fit the outer wall of the ladle opening, further improving the accuracy of the cover and reducing offset.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a steel ladle cover structure that is not easily deviated, including a steel ladle cover 1. A hook 4 for positioning is fixedly connected to the left side of the steel ladle cover 1. Three sets of triangularly distributed interdigitated seats 6 are fixedly connected to the upper part of the steel ladle cover 1. The three sets of interdigitated seats 6 form an isosceles triangle stable structure. One set is located at the left end of the central axis of the steel ladle cover 1, and the other two sets are symmetrically distributed on both sides of the right end of the central axis. The overall structural stability is improved by the three-point positioning principle. The two ends of the pin shaft 5 are limited by the shaft retaining ring to prevent axial fall-off. In order to reduce the wear of the pin shaft 5 during repeated cap addition and removal operations, the pin shaft 5 is designed to be rotatable. A pin shaft 5 is inserted in each set of interdigitated seats 6. Positioning components 2 are provided on the two sets of interdigitated seats 6 on the right side. The positioning components 2 include a guide plate 24 sleeved on the outside of the pin shaft 5. The guide plate 24 is cut and formed from steel plate.

[0019] Furthermore, a positioning block 22 is fixedly connected to the left surface of the guide plate 24. Slide plates 23 are fixedly connected to both the left and right sides of the front surface of the positioning block 22. Three sets of positioning rods 25 are vertically and evenly fixedly connected to the front surface of the positioning block 22 between the two sets of slide plates 23. The outer walls of the three sets of positioning rods 25 are connected to a fixing frame 21 through which a fixed frame 21 is slidably connected. The lower horizontal part of the fixing frame 21 is fixedly connected to the ladle cover 1 by bolts. The fixing frame 21 is fixedly connected to the ladle cover 1. The fixing frame 21 and the positioning block 22 are elastically connected by springs 26 respectively sleeved on the outer walls of the three sets of positioning rods 25. The springs 26 are made of 50CrVA spring steel. The elastic force keeps the guide plate 24 close to the middle position. By pressing the triangular inclined surface of the positioning block 22 with the tooth-inserting mechanism and cooperating with the multiple sets of springs 26, the tooth-inserting can be stably positioned between the two sets of guide plates 24, thereby preventing the tooth-inserting from shifting and causing the ladle cover to shift, thus achieving a good positioning effect.

[0020] Furthermore, the positioning block 22 is triangular in shape, and the fixing frame 21 is T-shaped. Its horizontal part is fixedly connected to the ladle cover 1, and its vertical part has a guide hole for the positioning rod 25 to pass through. The cooperation between the guide hole and the positioning rod 25 ensures that the positioning rod 25 can only slide along the axial direction. The positioning components 2 are set in two groups, and the two groups of positioning components 2 are symmetrically arranged with the center line of the pin 5 as the axis of symmetry. The guide plates 24 of the two groups of positioning components 2 are arranged opposite to each other, and the two groups of guide plates 24 are arranged opposite to each other to form a clamp-type positioning structure. When the cover opening mechanism is inserted, the two groups of positioning blocks 22 automatically center under the action of the spring 26 to reduce the error between the ladle and the cover. The outer wall of the ladle cover 1 is also provided with an anti-offset component 3 for limiting the offset.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The anti-deviation component 3 includes two sets of guide blocks 31, which are fixedly connected to the front and rear outer walls of the ladle cover 1 and are symmetrically arranged along the center line of the ladle cover 1. The opposite surfaces of the two sets of guide blocks 31 are set as inclined surfaces, which gradually slope downwards and inwards. When the ladle cover 1 is closed, the inclined surfaces contact the outer wall of the ladle opening, and the inclined surfaces position and limit the deviation. The top of the inclined surface of the guide block 31 and the bottom end of the ladle cover 1 are set as an arc surface. The arc surface fits against the outer wall of the ladle opening to increase the accuracy of the closing and reduce the deviation. The outer wall of the pin 5 is fitted with a buffer sleeve 32, which is made of high temperature resistant elastic material. The buffer sleeve 32 absorbs vibration energy through elastic deformation, reduces rigid impact, and further suppresses the deviation.

[0022] Working principle: During use, when the cap-opening mechanism inserts its pins, it presses against the inclined surfaces of the triangular positioning blocks 22 connected to the two sets of guide plates 24 on the right side. This causes the positioning blocks 22 to move outward, pressing against multiple sets of springs 26. The elastic force of the multiple sets of springs 26 keeps the guide plates 24 close to the center. Under the combined action of the pin's pressing force and the spring force of the springs 26, the pins can be stably positioned between the two sets of guide plates 24. The two sets of guide plates 24 form a clamp-type positioning structure, and the two sets of positioning blocks 22 are positioned by the springs 26. Automatic centering under action effectively prevents the ladle cover from shifting due to tooth misalignment. When the ladle cover 1 is closed, the inclined surface of the guide block 31 contacts the outer wall of the ladle edge. The inclined surface positions and limits the ladle cover from shifting. At the same time, the top of the inclined surface of the guide block 31 and the bottom of the ladle cover 1 are set as an arc surface. The arc surface fits the outer wall of the ladle edge to increase the accuracy of closing. In addition, the buffer sleeve 32 made of high temperature resistant elastic material is sleeved on the outer wall of the pin 5. It can absorb vibration energy through elastic deformation, reduce rigid impact, and further prevent the ladle cover from shifting.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
