Description

Technical Field

[0001] This utility model relates to the field of ladle cover technology in the steelmaking industry, and in particular to a ladle cover structure that prevents it from falling off. Background Technology

[0002] The ladle cover, also known as the ladle insulation cover or ladle covering system, is a crucial structure in the steel smelting process. It is primarily used to cover the ladle containing molten steel, serving multiple functions including heat preservation, energy saving, and improving the working environment.

[0003] In the steel smelting process, the ladle needs to be tilted to empty slag. During this process, the ladle cover is prone to detaching from the top of the ladle, affecting not only the efficiency of steel mill production but also posing safety hazards. To address this technical problem, publicly available ladle cover technologies focus primarily on the clamping and limiting aspects of the connection components between the ladle cover and the ladle. They address less of the technical issues arising when the ladle is tilted, especially at angles exceeding 90°, and the ladle cover opens, causing the connection components to bear the entire weight of the cover and potentially damaging them, thus rendering the ladle cover technology unusable.

[0004] Furthermore, the disclosed ladle cover technology does not include a buffer component. If the ladle is tilted too quickly, the impact on the ladle cover will be too great, causing it to sway and shake due to inertia. This is not conducive to slag removal and increases the impact on the connecting components. Summary of the Invention

[0005] The main objective of this invention is to provide a structure for preventing the steel ladle cover from falling off, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model proposes an anti-fall-off steel ladle cover structure, comprising: Steel ladle cover body; A connecting component connects the ladle cover body to the ladle, allowing the ladle cover body to rotate relative to the ladle. A buffer assembly includes a mounting base, a movable block, an elastic element, a limiting element, and a first connecting element. The mounting base is mounted on a ladle and has a cavity extending through one end of the mounting base. The movable block is disposed within the cavity and is movable relative to the mounting base. The first connecting element connects the movable block to the ladle cover body. The elastic element is disposed at the end of the cavity opposite to the movable block and away from the first connecting element, and its two ends are respectively connected to the mounting base and the movable block. The limiting element is installed at the end of the cavity opposite to the movable block and away from the elastic element, and can abut against the movable block.

[0007] In an alternative embodiment, the first connector is a chain.

[0008] In an optional embodiment, the connecting assembly includes a first hinge seat, a second hinge seat, and a hinge shaft. The first hinge seat is mounted on the ladle and has a first hinge hole. The second hinge seat is mounted on the ladle cover body and has a second hinge hole. The hinge shaft is received within the first hinge hole and the second hinge hole.

[0009] In an optional embodiment, the top and bottom surfaces of the movable block are respectively connected to the first connecting member and the elastic member, and the four sides of the movable block abut against the mounting base so that the movable block can slide relative to the mounting base. The limiting member abuts against the top surface of the movable block.

[0010] In an alternative embodiment, the buffer assembly further includes a second connector made of thermally insulating material, and the mounting base is mounted on the ladle via the second connector.

[0011] In an optional embodiment, the buffer assembly further includes a third connector and a fourth connector. One end of the third connector is mounted on the steel ladle cover body, and the other end has a first connection hole. One end of the fourth connector is mounted on the movable block, and the other end has a second connection hole. The two ends of the first connector are respectively connected to the third connector and the fourth connector through the first connection hole and the second connection hole.

[0012] In an optional embodiment, an anti-fall-off steel ladle cover structure further includes another buffer component, and the two buffer components are symmetrically arranged with respect to the axis of the steel ladle cover body.

[0013] In an optional embodiment, an anti-fall-off ladle cover structure further includes two lifting lugs, which are installed at one end of the ladle cover body opposite to the ladle. Compared with the prior art, the present invention has the following technical effects: This utility model's anti-fall-off ladle cover structure employs a connecting component and a buffer component. These components work together to hold the ladle cover body in place when the ladle tilts and the cover body opens to pour slag, preventing the cover body from detaching from the ladle. The buffer component also cushions the ladle cover body during opening, preventing excessive impact from rapid tilting and causing the cover body to sway due to inertia, which would hinder slag pouring and increase impact on the connecting component, thus enhancing the safety of the anti-fall-off ladle cover structure.

[0014] When the ladle cover is opened to its limit position, the buffer component can also share part of the weight of the ladle cover with the connecting component, avoiding the connecting component bearing all the weight of the ladle cover and increasing the risk of damage to the connecting component, thus improving the safety of the anti-detachment ladle cover structure.

[0021] Reference Figures 1-4 This utility model proposes a steel ladle cover structure 100 that prevents it from falling off.

[0022] In this embodiment of the invention, the anti-fall-off ladle cover structure 100 includes a ladle cover body 1, a connecting component 2, and a buffer component 3. The connecting component 2 connects the ladle cover body 1 to the ladle 200, so that the ladle cover body 1 can rotate relative to the ladle 200.

[0023] Please refer to Figure 4 The buffer assembly 3 includes a mounting base 301, a movable block 302, an elastic element 303, a limiting element 304, and a first connecting element 305. The mounting base 301 is mounted on the ladle 200 and has a cavity 306 that passes through one end of the mounting base 301. The movable block 302 is located in the cavity 306 and can move relative to the mounting base 301. The first connecting element 305 connects the movable block 302 to the ladle cover body 1. The elastic element 303 is located at the end of the cavity 306 away from the movable block 302 and away from the first connecting element 305, and its two ends are connected to the mounting base 301 and the movable block 302 respectively. The limiting element 304 is installed at the end of the cavity 306 away from the movable block 302 and away from the elastic element 303, and can abut against the movable block 302. A spring can be used as the elastic element 303. That is, in the direction through which the mounting base 301 is penetrated, the movable block 302 is located between the elastic member 303 and the limiting member 304, and the first connecting member 305 is connected to the side of the movable block 302 opposite to the elastic member 303.

[0024] Please refer to Figure 2 and Figure 3Specifically, both the ladle cover body 1 and the ladle 200 have circular cross-sections. One end of the ladle cover body 1 covers one end of the ladle 200. The connecting assembly 2 includes a first hinge seat 201, a second hinge seat 202, and a hinge shaft 203. The first hinge seat 201 is mounted on the ladle 200, specifically on its side, and has a first hinge hole. The second hinge seat 202 is mounted on the ladle cover body 1, specifically on its side, and has a second hinge hole. The hinge shaft 203 is received within the first and second hinge holes. The first hinge seat 201 and the second hinge seat 202 are rotatably connected via the hinge shaft 203. Taking the ladle 200 as a reference body, the ladle cover body 1 can rotate relative to the ladle 200.

[0025] Please refer to Figure 4 The buffer assembly 3 also includes a second connector 307, which is made of heat-insulating material. The mounting base 301 is mounted on the ladle 200 via the second connector 307, reducing the impact of the high temperature of the ladle 200 on the mounting base 301. The second connector 307 can be made of foamed cement, ceramic fiber, or vacuum insulation board. The cavity 306 penetrates one end of the mounting base 301, with the penetrated end of the mounting base 301 facing the ladle cover body 1.

[0026] In order to make the connection and movement of the steel ladle cover body 1 and the movable block 302 smoother, an iron chain is used as the first connecting member 305. One end of the first connecting member 305 is connected to the steel ladle cover body 1, and the other end can pass through the through hole of the mounting base 301 into the cavity 306 and connect with the movable block 302.

[0027] The movable block 302 is rectangular in shape and has a top surface and a bottom surface opposite to each other, as well as four side surfaces. All four side surfaces are connected to the top surface and the ground surface, respectively. A first connecting member 305 and an elastic member 303 are connected to the top and bottom surfaces of the movable block 302. The four side surfaces of the movable block 302 abut against the mounting base 301, allowing the movable block 302 to slide relative to the mounting base 301. A limiting member 304 abuts against the top surface of the movable block 302. The abutment of the four side surfaces of the movable block 302 against the mounting base 301 allows for smoother movement of the movable block 302 within the cavity 306 relative to the mounting base 301.

[0028] The buffer assembly 3 also includes a third connector 308 and a fourth connector 309. One end of the third connector 308 is mounted on the steel ladle cover body 1, and the other end is provided with a first connection hole 310. One end of the fourth connector 309 is mounted on the movable block 302, and the other end is provided with a second connection hole 311. The two ends of the first connector 305 are respectively connected to the third connector 308 and the fourth connector 309 through the first connection hole 310 and the second connection hole 311.

[0029] In one embodiment of this utility model, the anti-fall-off steel ladle cover structure 100 further includes another buffer component 3, and the two buffer components 3 are symmetrically arranged with respect to the axis of the steel ladle cover body 1. The provision of two buffer components 3 enhances the buffering capacity of the steel ladle cover body 1 and distributes more of the weight of the steel ladle cover body 1 to the connecting component 2.

[0030] Please refer to Figure 1 In one embodiment of this utility model, the anti-falling ladle cover structure 100 further includes two lifting lugs 4, which are installed at one end of the ladle cover body 1 opposite to the ladle 200. The two lifting lugs 4 facilitate the installation or removal of the ladle cover body 1 from the ladle 200.

[0031] In this application, when the slag dumping process is carried out, the ladle 200 is tilted, and the ladle cover body 1 rotates relative to the ladle 200 with the connecting component 2 as the fulcrum, and opens from the ladle 200 to realize slag dumping. The connecting component 2 and the buffer component 3 are connected together to the ladle cover body 1 to prevent the ladle cover body 1 from falling off.

[0032] When the ladle cover body 1 is opened from the ladle 200, the ladle cover body 1 pulls the first connecting piece 305 and the movable block 302 together. The elastic element 303 holds the movable block 302, so that the ladle cover body 1 is buffered when it is opened, so as to avoid the ladle 200 tipping over too fast, the ladle cover body 1 being impacted too much, the ladle cover body 1 swaying due to inertia, which is not conducive to dumping slag and increases the impact on the connecting component 2.

[0033] When the ladle cover body 1 is opened to the limit position, the movable block 302 abuts against the limit block, and the first connector 305 pulls the ladle cover body 1, so as to share part of the weight of the ladle cover body 1 with the connecting component 2, thereby avoiding the connecting component 2 bearing all the weight of the ladle cover body 1 and increasing the risk of damage to the connecting component 2.

[0034] Once the slag removal is complete, the ladle 200 is uprighted, and the ladle cover body 1 rotates relative to the ladle 200 with the connecting component 2 as a fulcrum, then re-covers the ladle 200. Simultaneously, the elastic element 303 pulls the movable block 302 and the first connecting component 305 back to their original positions. When the ladle cover body 1 is completely placed on the ladle 200, the elastic element 303, the movable block 302, and the first connecting component 305 hold the ladle cover body 1 in place, enhancing its stability on the ladle 200.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
