[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Embodiment: As Figures 1-5 shown, the present invention provides a technical solution, a device for quickly processing the slag scraping table at the edge of a hot-repaired steel ladle, including a base 1. A support platform 2 is fixedly connected to the top end of the base 1. Gantries 3 are symmetrically installed on one side of the support platform 2. A scraping plate 4 is arranged on one side of the gantry 3. And slag scraping teeth 5 are evenly arranged at the end of one side of the scraping plate 4. The slag scraping teeth 5 evenly arranged at the end of the scraping plate 4 form a serrated shape. The edge of the slag scraping teeth 5 contacts the edge of the steel ladle lifted by the overhead crane. It is convenient to make the slag scraping teeth 5 quickly scrape and process the too-high edge of the steel ladle through the contact between the slag scraping teeth 5 and the edge of the steel ladle, so as to realize the quick processing of the edge of the steel ladle;

[0029] The inner sides of the tops of the two gantries 3 are rotatably connected with a rotating seat 6. The rotating seat 6 is rotatably connected with the two gantries 3 through a movable rotating shaft 7 inside it. An end seat 8 for disassembly and assembly is fixedly connected to the end of the rotating seat 6. A limiting groove 9 is opened inside the end seat 8 for disassembly and assembly. The other end of the scraping plate 4 is limited and installed inside the end seat 8 for disassembly and assembly through a mounting seat 10. And a disassembly and assembly screw 11 is threadedly connected to the top of the end seat 8 for disassembly and assembly. The mounting seat 10 and the limiting groove 9 are tightly fitted and clamped. The disassembly and assembly screw 11 passes through the end seat 8 for disassembly and assembly and is screwed into the mounting seat 10 through threads, which is convenient for the tight clamping between the mounting seat 10 and the end seat 8 for disassembly and assembly. At the same time, it is convenient to limit the position between the mounting seat 10 and the end seat 8 for disassembly and assembly through the disassembly and assembly screw 11 to ensure the stability of the subsequent installation of the scraping plate 4;

[0030] On both sides of the rotating base 6, fitting grooves 12 are provided at positions outside the movable rotating shaft 7. A torsion spring 13 is embedded and connected inside the fitting groove 12. The torsion spring 13 is sleeved outside the movable rotating shaft 7. One end of the torsion spring 13 is fixedly connected to the inner wall of the fitting groove 12, and the other end is fixedly connected to the side of the gantry 3, which facilitates the connection of the torsion spring 13 and is convenient for driving the torsion spring 13 to deflect when the movable rotating base 7 rotates, so as to facilitate providing elastic support for the movable rotating base 7, enabling the scraping plate 4 to be in closer contact with the ladle lip during the treatment process, and at the same time avoiding excessive contact and scraping pressure between them from damaging the slag scraping teeth 5.

[0031] Equidistant leakage grooves 14 are provided at the top of the support platform 2, and anti-slip strips 15 are adhesively bonded to the top surface of the support platform 2 at positions on the sides of the leakage grooves 14. A transverse plate 16 is embedded and slidably connected inside the top of the support platform 2. A fitting groove 17 with the same spacing as the leakage grooves 14 is provided inside the transverse plate 16. A guide groove 18 is provided at one side end of the top of the support platform 2. A limit bolt 19 is connected to the side of the transverse plate 16 corresponding to the guide groove 18. The limit bolt 19 on the side of the transverse plate 16 slides inside the guide groove 18, and the length of the guide groove 18 is equal to the spacing between two adjacent leakage grooves 14 and fitting grooves 17, and the inner diameters of the leakage grooves 14 and the fitting grooves 17 are equal, which facilitates the sliding of the transverse plate 16 and is convenient for restricting its position. At the same time, by moving the position of the transverse plate 16, it is convenient to adjust the position of the fitting groove 17 inside it, so as to facilitate the blocking and contact closing of the leakage grooves 14, and thus facilitate the rapid collection of the broken pieces of the ladle lip scraped off.

[0032] A sliding groove 20 is provided inside the support platform 2 at the bottom position of the transverse plate 16. A collection box 21 is embedded and fitted and slidably connected inside the sliding groove 20.

[0033] The working principle and usage process of the present utility model: In the actual application process of this rapid treatment slag scraping platform device for hot repairing the ladle lip, first, the gantry 3 is installed on both sides of the support platform 2 so that the position of the gantry 3 corresponds to the ladle pouring area. The support platform 2 is stably supported by the base 1, and the anti-slip strips 15 at the top of the support platform 2 facilitate the placement of the ladle to be treated, and when the ladle is being treated, the ladle is connected to the overhead crane lifting device;

[0034] Then, the scraping plate 4 is clamped in the limiting groove 9 inside the disassembly and assembly end seat 8 through the mounting seat 10 at its end, and the position between the mounting seat 10 and the disassembly and assembly end seat 8 is fixed by the disassembly and assembly screws 11, realizing the rapid installation of the scraping plate 4 and the slag scraping teeth 5. Through the convenient disassembly and assembly connection between the mounting seat 10, the disassembly and assembly end seat 8, and the limiting groove 9, it is convenient for the rapid installation and convenient disassembly of the mounting seat 10 and the scraping plate 4 and the slag scraping teeth 5 at its end, and it is also convenient for the disassembly and replacement of the scraping plate 4 and the slag scraping teeth 5 for use, avoiding the situation where when the slag scraping teeth 5 are damaged, the excessive ladle lip at the edge of the ladle cannot be effectively treated;

[0035] During the specific treatment process, mainly utilize the intermittent time of ladle slag pouring. After the ladle slag pouring is completed, the crane operator commands the overhead crane to lift the ladle, so that contact is made between the edge of the ladle and the slag scraping teeth 5 at the end of the scraping plate 4. Then, by using the lifting force of the overhead crane, friction is generated between the slag scraping teeth 5 and the edge of the ladle. Through the friction between them, the excessively high ladle edge at the edge of the ladle is separated and detached from the ladle.

[0036] During the process of contact between the edge of the ladle and the slag scraping teeth 5, the scraping plate 4 is driven to rotate inside the gantry 3 through the rotating seat 6, the disassembly and installation end seat 8, and the mounting seat 10. In cooperation with the fitting groove 12 and the torsion spring 13, when the movable rotating seat 7 drives the scraping plate 4 to rotate, it is convenient to drive the torsion spring 13 to deflect. By using the torsional action of the torsion spring 13, elastic support is provided for the movable rotating seat 7 and the scraping plate 4, so that during the treatment process, the scraping plate 4 can be in closer contact with the edge of the ladle, and at the same time, damage to the slag scraping teeth 5 caused by excessive scraping pressure during the contact between them is avoided, improving the treatment effect of the excessively high ladle edge at the edge of the ladle.

[0037] By the above treatment method, the original method of hot repairing the ladle edge is changed. Utilize the intermittent time of slag pouring to handle the problem of excessively high ladle edge, save 5 - 7 minutes of the time for hot repairing the ladle edge, improve the fluency of the production process, and effectively shorten the connection time between the upper and lower processes, ensure the stable casting of the continuous casting process, and at the same time provide ladles for the converter efficiently and with high quality, reducing the turnover pressure of the ladles.

[0038] When dealing with the excessively high ladle edge, the alignment and misalignment between the leakage trough 14 and the fitting groove 17 are carried out by the movement of the cross plate 16. The guide groove 18 and the limit bolt 19 facilitate the limitation of the edge of the cross plate 16 when its position moves, so that the fitting groove 17 inside the cross plate 16 can be more accurately aligned and misaligned with the leakage trough 14, so as to facilitate the anti-blocking and contact closing of the top of the support platform 2, and facilitate the effective treatment of the fragments generated during the ladle edge treatment. In cooperation with the sliding groove 20 and the collection box 21, it is convenient to quickly collect the excessively high ladle edge fragments scraped during the slag scraping process, so as to facilitate the subsequent convenient cleaning of the ladle edge fragments and avoid the phenomenon of ladle edge slag scattering.

[0039] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
