Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] Reference Figures 1-3The utility model provides an embodiment: a kind of steel manufacturing is scraped with device, including support frame 1, the top of support frame 1 is provided with hydraulic rod 2, hydraulic rod 2 is a kind of execution element using hydraulic energy to carry out linear reciprocating motion, can be moved vertically by hydraulic rod 2 with entire drive box 3 and support plate 4, the movable end of hydraulic rod 2 is fixedly connected with drive box 3, motor is provided in drive box 3, and the output end of motor is connected with the top of support plate 4, can let support plate 4 rotate, the bottom of drive box 3 is provided with support plate 4, the bottom of support plate 4 has small scraper, small scraper is mainly scraped to the inside bottom of ladle, the upper portion of support frame 1 is fixedly connected with fixed ring 5, and fixed ring 5 is mainly supported with the effect of connecting sliding block 6, the inner wall of fixed ring 5 is slidably connected with sliding block 6, and the end of sliding block 6 away from fixed ring 5 is hinged with mounting plate 8 by hinged lever 7, and mounting plate 8 is mainly supported and connected with the effect of scraper 9, and the inner wall of mounting plate 8 is detachably installed with scraper 9, and the inner wall of ladle used in steel manufacturing can be scraped by scraper 9, the side wall of support plate 4 is fixedly connected with extrusion block 10, and extrusion block 10 is inclined, so that the inclined surface of extrusion block 10 extrudes knock plate 12 to move, the inner wall of support frame 1 is provided with placement table 15, and placement table 15 is mainly placed with the effect of ladle, to facilitate subsequent scraping treatment in ladle, the inner wall of support frame 1 is provided with knock mechanism, the side wall of scraper 9 is provided with dismounting assembly, and knock mechanism includes knock plate 12, and knock plate 12 is slidably connected on the inner wall of support frame 1, and knock plate 12 has protruding block and is steel material, with certain hardness, and will not be deformed for long time use, and the outside of knock plate 12 is elastically connected with support frame 1 by reset spring 11.

[0031] Refer to Figure 3 , and dismounting assembly includes connecting rod 13, and connecting rod 13 is fixedly connected on the side wall of scraper 9, and the surface of connecting rod 13 has texture, so that connecting rod 13 and fastening nut 14 are twisted and installed, and the outer wall of connecting rod 13 is threadedly connected with fastening nut 14, and connecting rod 13 is inserted in the inner wall of mounting plate 8.

[0032] Refer to Figures 1-3The outer side of the striking plate 12 is fixedly connected to one end of the return spring 11. The return spring 11 is initially compressed. When resetting, the spring force of the return spring 11 moves the striking plate 12 to the left. The other end of the return spring 11 is fixedly connected to the inner side wall of the support frame 1. The mounting plate 8 is slidably connected to the inner wall of the support plate 4. The support plate 4 has a slot, which allows the hinge rod 7 to move along the mounting plate 8. The outer wall of the pressing block 10 is in contact with the upper end of the striking plate 12. There are two sets of striking plates 12, which are symmetrically distributed on the inner side wall of the support frame 1. The end of the slider 6 away from the fixed ring 5 is hinged to one end of the hinge rod 7. Since the length of the hinge rod 7 is fixed, when the support plate 4 moves downward, the hinge rod 7 and the mounting plate 8 will separate from each other. When the support plate 4 moves upward, the hinge rod 7 and the mounting plate 8 will move closer together. The other end of the hinge rod 7 is hinged to the top of the mounting plate 8.

[0033] Working principle: When cleaning the inner wall of a steel ladle used in steel manufacturing, the ladle is transported to the placement platform 15 via an external device, positioning the entire area of ​​the striking plate 12 above the ladle. Then, the hydraulic rod 2 is activated, moving the drive box 3, support plate 4, and extrusion block 10 downwards, allowing the scraper 9 to enter the ladle. The hinge rod 7, carrying the mounting plate 8 and scraper 9, moves towards the inner wall of the ladle, bringing the scraper 9 into contact with the inner wall. Then, the motor in the drive box 3 drives the support plate 4, extrusion block 10, mounting plate 8, hinge rod 7, and slider 6 according to... Figure 2 Rotating clockwise, the scraper 9 scrapes away impurities from the ladle. As the support plate 4 rotates, the squeezing block 10 separates from the striking plate 12. Since the initial state of the return spring 11 is compressed, the squeezing block 10 does not contact the striking plate 12. The reverse elastic force of the return spring 11 causes the striking plate 12 to return and impact the outer wall of the ladle, causing the outer wall of the ladle to vibrate and transmit the vibration to the inner wall. Due to inertia, the steel slag and other impurities attached to the inner wall move relative to the inner wall of the ladle, thus loosening and falling off. As the entire support plate 4 rotates with the squeezing block 10, the squeezing block 10 continuously squeezes the striking plate 12, moving it to the right when it is not in contact with it and then moving it to the left to impact the ladle, thus improving the subsequent cleaning efficiency.

[0034] When the scraper 9 needs to be replaced, simply turn the fastening nut 14 to separate the fastening nut 14 from the connecting rod 13, and then remove the scraper 9 from the mounting plate 8. During installation, simply insert the scraper 9 and the connecting rod 13 into the mounting plate 8 at their initial installation positions, and finally turn the fastening nut 14 to install the entire scraper 9.

[0035] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
